Patterned remittances enhance women's health-related autonomy

The consequences for women “left behind” by virtue of temporary male migration are mixed. On the one hand, concomitant changes in fertility, participation in the labor force, and social norms are often associated with increased independence for women. On the other hand, women left behind can be vulnerable to increased dependency on members of their husbands' family or face limited access to social institutions. These shifts in women's capacity for decision making can have important implications for their health and well-being. Focusing on the state of Kerala in southern India, we examine the conditions under which the remittances that migrants send home have an impact on the health of women left behind. Specifically, we assess the extent to which the timing of remittance sending can support women's autonomy and improve their ability to make autonomous healthcare decisions. We use evidence from migrant households in Kerala, a region deeply engrained in the world labor migration system for more than five decades. Analysis is conducted with data from the 2016 wave of the Kerala Migration Survey (KMS), a representative household survey, and paired with in-depth qualitative interviews with women in Kerala whose husbands and other family members have migrated to the Gulf. We show that the positive effect of remittances on women's autonomy manifests primarily through the timing of remittance receipt, not the amount of money remitted. Regular remittances are associated with higher levels of autonomy than remittances received at irregular intervals, net of amount remitted. This finding challenges the usual emphasis on remittance volume as the driving factor of social and behavioral change in sending communities. Analytical efforts should be refocused on the social-interactional component of remittance sending and how these interactions can impact women's health and autonomy.


Introduction
This article considers the conditions under which temporary migration of a primarily male workforce is beneficial to women's autonomy, a crucial determinant of women's health. Temporary male migration in search of work is a characteristic feature of many developing countries. The consequences for women left behind are known to be mixed (Desai & Banerji, 2008;Gulati, 1983). On the one hand, male migration can indirectly lead to greater independence for women left behind through a host of economic and social changes "remitted" back to sending communities, and remitted wages can directly support higher quality of life overall (Adger, Kelly, Winkels, Huy, & Locke, 2002;Yabiku, Agadjanian, & Sevoyan, 2010). On the other, women left behind can be vulnerable to the challenges that come with an absent male head of household, such as dependence on their in-laws or difficulty accessing loans (Datta & Mishra, 2011;Leno€ el, 2017). Remittances can also be unreliable sources of income, leaving families in situations of financial precarity (Lu, 2012;Wells, Lyn, Mclaughlin, & Díaz Mendiburo, 2014).
The changes that accompany temporary male migration can have implications for the health and well-being of women left behind-for instance, on the degree to which they experience stress or access nutrition. In this article, we focus on the implications for women's autonomy in making decisions about and seeking their own healthcare-factors known to be associated with objective health outcomes (Bloom, Wypij, and Das Gupta, 2001;Kawachi, Kennedy, & Prothrow-Stith, 1999).
To assess how women's health might be affected, we link research on the impact of remittances with research on women's autonomy, assessing the conditions under which remittances improve women's ability to make autonomous healthcare decisions. Drawing on extant definitions, we consider autonomy to comprise the extent to which women are involved in making decisions about their own health and healthcare and the extent to which they are free to move about and enact those decisions. We focus on migrant remittance sending, proposing that it will bolster the autonomy of women left behind only under certain conditions-and that these conditions are about when remittances are sent rather than how much money is remitted.
This study examines households that are part of a robust migration flow between the Indian state of Kerala and the countries in the Gulf Cooperation Council (GCC). Rapid development and high demand for employment mean that the GCC states receive some of the largest flows of temporary labor migration in the world. In many of these countries, foreign-born workers constitute a majority of the population: approximately 88% in the United Arab Emirates, 75% in Qatar, and 74% in Kuwait (Connor, 2016). The majority of these foreign-born temporary workers are men from India, Bangladesh, and Pakistan, with one-or two-year visas, and the vast majority send remittances to their home communities. With its long history of Gulf migration, Kerala provides an ideal site for a study of migrant households; although given Kerala's exceptionally low fertility rate and high levels of literacy, caution should be exercised when extending these generalizations to other migrant-sending regions (Susuman, Lougue, & Battala, 2016).

Women's autonomy and women's health
Autonomy involves both actual capacities to plan and act independently and subjective perceptions thereof. Researchers have chosen to focus on various aspects of autonomy but have generally agreed that it includes some "capacity to manipulate one's personal environment through control over resources and information, including freedom of movement, in order to make decisions about one's own concerns or about close family members" (Bloom et al., 2001;Mistry, Galal, & Lu, 2009). That is, the capacity to make decisions requires both making plans and accessing resources with which to carry out those plans. We utilize these interrelated but separable components of autonomy in this study. They are especially important when it comes to health. Seeking healthcare and planning for one's health requires an orientation toward the long-term future. It also requires that women can physically carry out their plans, which may include visits to far-off clinics and significant changes in health behavior.
Women's autonomy is important in its own right and is crucially linked to women's health and health-related behavior. In the United States, research shows that higher levels of autonomy for women are correlated with lower levels of maternal and child mortality and lower levels of depression (Chen, 2005;Kawachi et al., 1999). Elsewhere, greater autonomy and freedom of movement for women were also associated with higher rates of obtaining prenatal and antenatal care (Ghose et al., 2017;Mistry et al., 2009;Woldemicael & Tenkorang, 2010), as well as lower levels of unmet need for contraception and higher awareness of contraceptive options (Allendorf, 2010). This can be true even when decision-making power is not explicitly related to health: research using the Nigerian Demographic and Health Survey demonstrated a significant and positive relationship between women's household decision-making and use of modern contraceptives (OlaOlorun & Hindin, 2014). Although research in developing countries has largely focused on women's reproductive health, a few studies have discussed the link between women's autonomy and health outcomes in other areas, such as cancer screening and treatment (Osamor & Grady, 2016).
The link between healthcare and autonomy can be observed across different operationalizations of autonomy, whether focused on decision making, freedom of movement, or women's subjective status (Bloom et al., 2001;Kawachi et al., 1999;Mistry et al., 2009). A host of studies from several different contexts demonstrate that variation in the degree to which women have autonomy is associated with differences in health outcomes. Thus, the dynamics that impact women's autonomy will also have implications for women's health.

Temporary male migration and Women's autonomy
Remittances from temporary workers to home communities are often significant sources of additional income for migrant families, allowing for greater financial prosperity and household purchasing power (Nziramasanga & Yoder, 2013;Zachariah & Rajan, 2015). This impacts both short-term consumption and longer-term investments: for instance, remittances can be invested in children's education, and having a migrant in the household is in many cases associated with increased educational attainment for migrant children (Antman, 2012;Zachariah, Mathew, and Irudaya Rajan 2001a,b). Remittances also contribute to regional economic growth as a whole, potentially reducing wealth inequalities as migration becomes more ubiquitous in the community, even though it may increase income inequality at the onset (Mckenzie & Rapoport, 2007;Odozi, Awoyemi, & Omonona, 2010;Stark, Taylor, & Yitzhaki, 1986). Temporary migration additionally serves to relieve unemployment in sending countries, thereby raising wages for those who remain behind (Taylor, 1999).
Although research into women's autonomy has focused on structural effects of migration, such as a husband's absence or residence with inlaws, it has paid little attention to remittance sending. There is evidence of the link between male migration and increased autonomy for women left behind both as a direct result of male absence and an indirect result of migration's effects on social structure and family formation. Yet research in the same vein suggests that there are situations in which male migration can have negative implications for the autonomy of women left behind.
One pathway for male migration to change sending communities is through its impact on fertility. Absent spouses can disrupt planned fertility, and greater wealth or encounters with new norms can change household strategies for childbearing (Bertoli & Marchetta, 2015;Billari, Philipov & Testa, 2009). High out-migration areas in developing countries often see decreased birth rates over time, leading researchers to posit that temporary migration precipitates a second demographic transition in developing countries (Bertoli & Marchetta, 2015;Lindstrom & Saucedo, 2002). Male migration can also prompt changes in women's participation in the labor force. Women may do less unpaid household work and more work outside of the home (Khan & Valatheeswaran, 2016), although this too is dependent on the presence of social constraints and the availability of outside employment opportunities for women (Durand & Massey, 2004). Provided that the work is done outside of the household and comes with wage earnings, women's employment correlates with an increase in their autonomy (Anderson & Eswaran, 2009).
Researchers have proposed that gains to women's autonomy reflect the "social remittances" migrants bring from receiving countries in the form of changed behavior (Levitt, 2001). For instance, receiving country fertility norms might influence migrants' childbearing preferences or change their attitude towards contraception, with effects on their independence from family life (Liew, 2007). Gains in women's autonomy may also reflect shifting household structure: for instance, when the absence of men requires women in migrant households to take on greater roles in decision making in areas such as household purchases and investments, healthcare, and children's education (K C Zachariah, Mathew, & Rajan, 2001a, 2001b. In the same vein, women may have increased mobility outside of the house by necessity. This dynamic may account for research that finds a direct effect of male migration on improving women's autonomy outside of its impacts on fertility and women's employment (Yabiku et al., 2010).
Yet temporary male migration can have negative effects on women's autonomy. In areas where women are expected to be accompanied by male companions in public, absent husbands and sons mean greater restrictions on where women can go. Research in Kerala and in rural Pakistan shows that when migrant remittances lead to greater household wealth, reduced need for women's participation in paid labor may decrease opportunities for women to have independent income (Khan & Valatheeswaran, 2016;Rafique Wassan, Hussain, Shah, & Amin, 2017). In Kerala, in rural Pakistan, and in Bangladesh, the enhanced status of male migrants has allowed men to exercise greater power of choice in marriage and divorce, with negative effects on women (Rahman, 2009;Rafique Wassan et al., 2017). The effects of male migration on the marriage market can extend beyond migrant spouses: in the Matlab region of Bangladesh, researchers find that a brothers' migration often led parents to exercise more control over a sister's marriage, prioritizing proximity in order to ensure care for themselves in their older age (Protik & Kuhn, 2006). Additionally, when marriage is patrilocal, women with absent husbands may be forced to cede to their in-laws' control over crucial decisions about health and healthcare.
Temporary migration aids family survival through remittances only when remittances are sufficient. Initially, migration can entail amassing significant debt to pay migration recruitment fees, as well as periods of uncertainty when wages are not regular or not as high as expected. Families can be left in situations of financial precarity. Women in migrant households are often left to manage relationships with creditors involved in sending the migrant abroad, in addition to other demands on household finances (Rahman and Fee, 2009). Families of temporary migrants are often uncertain about how much migrants earn and how much and when remittances will be sent (Seshan & Zubrickas, 2015). When remittances falter, families are left without outside resources and without the capacity to plan for the future. They may have to rely more heavily on in-laws or other community members (Wells et al., 2014).
In sum, studies on sending communities focus on the financial impact of remittances. These studies fall short of identifying the ways in which remittances have social impacts, although one study indicated minor protective effects of long-term remittance receiving on the psychological health of left-behind family members (Lu, 2012). Meanwhile, studies of women's autonomy tend to focus on other structural or social factors. Yet remittance sending itself is a social process, inscribing relationships between remitters and recipients and positioning both within a broader network of relationships (Carling, 2014).
Remittances also have a temporal component: they are sent at certain times and with certain frequencies. Variations in the amount remitted matter for a household's overall capacity for consumption, but variations in the timing of remittance crucially affect how well a household is able to plan for future consumption. Decisions about health and healthcare involve long-term planning and are more effective when one has stable expectations for the future. Thus, remittance timing, with respect to both pattern and frequency, may be especially salient for healthcare decisionmaking autonomy. Here, we bridge disparate literatures by focusing on how and under what conditions monetary remittances impact the health of women left behind through its impact on their autonomy. We posit that monetary remittances can impact the autonomy and health of women "left behind" such that those in households receiving more frequent and regular remittances will report higher levels of autonomy than those receiving remittances at irregular intervals.

Migration from Kerala
This analysis uses data from the state of Kerala, in southern India. India is one of the world's top remittance-receiving countries and Kerala is one of the largest emigrant-sending states in the country. In 2011, Kerala sent over two million workers abroad and received 31% of its net state domestic product from remittances. Migration has been a central driver of economic growth in Kerala since the mid-1900s, contributing to significant declines in poverty and unemployment across the state. Temporary migration has been increasing from Kerala to the GCC since the Kerala Migration Survey (KMS) began in 1998. Data collected during the first wave revealed that 1,400,000 individuals had emigrated and sent Rs 130 billion prior to 1998; the 2014 wave of the study found that 2,400,000 individuals had emigrated and sent Rs 710 billion back to Kerala between 1998(K C Zachariah & Rajan, 2015. Kerala is located geographically in Panel A of Fig. 1, and the historical pattern of out-migration from Kerala is reported in Panel B. As the largest sending district in Kerala, Malappuram offers an ideal site for understanding the impact of global migration from a sending country's perspective. The district's substantial migrant population has been instrumental in shaping Kerala's labor market and economic growth-it accounted for 18.8% of all emigrants from and approximately 20.0% of all remittances to Kerala in 2014 (Rajan, 2014). In practical terms, Malappuram is ideal because of the saturation of transnational households (K C Zachariah & Rajan, 2015). Many of the developmental gains in women's health and autonomy likely result from social changes already in place following past migration cycles. At 1.58, Kerala's total fertility rate is well below replacement level; female literacy is 92% (compared with a national average of 65%); contraceptive awareness is high; and infant mortality rates are the lowest in the country (Alukal, George, & Raveendran, 2018;Susuman et al., 2016). In these areas, any diffusion of normative change as a result of migration has already occurred; thus, we can rule out normative variation as a factor impacting women's autonomy today. The history and ubiquity of male migration and its effects also make Kerala a conservative study site, as differences in women's autonomy are far less likely to be due to variations in exposure to international migration, allowing us to identify more immediate determinants thereof. We focus here on women's reported participation in decision making and their freedom of movement, particularly relating to healthcare. In addition to having implications for women's objective health and well-being, these measures offer insight into women's subjective sense of changes in their own autonomy.

Study design
This study employs both semi-structured interviews and survey data to examine the social process of receiving remittances as a determinant of women's health in Kerala. Ethnographic research and semi-structured interviews conducted in Malappuram, Kerala, between 2016 and 2017 are the qualitative foundation of our analysis. Our fieldwork included interviews with 40 women from diverse caste and religious backgrounds sampled from each of the six subdistricts within Malappuram, with an eye toward population size and religious composition. We interviewed women about a wide range of topics, including their family lives, social and political participation, and hopes for the future, seeking to examine how male migration to the GCC shapes the lived experiences of women who do not migrate themselves but are still significantly impacted by the process. Interviews were recorded, transcribed, and coded after anonymization, and are stored in a secure location. We pair these narratives with statistical analysis, using data from the 2016 wave of the Kerala Migration Survey (KMS), a representative longitudinal household survey conducted in Kerala. The survey has been described in detail elsewhere (See Kunniparampil Curien Zachariah & Rajan, 2015). The 2016 KMS dataset includes a gender module that focuses on the women left behind after family members migrate for economic opportunities. The 2016 dataset includes information on 55,276 individuals in 13,199 households, including 2834 married women aged 15-49 years who were individually interviewed for the gender module. We excluded participants who are missing data for the outcome (change in mobility to healthcare centers, n ¼ 93) or for any covariates (husband's residence, n ¼ 26; women's employment status, n ¼ 12; and whether or not they are receiving remittances directly, n ¼ 66). Most of the women excluded were missing data for multiple variables. In total, we removed 85 participants, and our final sample size is 2749. From this, we used a sample of 689 women who were in migrant households that received remittances.

Measures of autonomy
Using data from the Kerala migration survey, we measure two dimensions of change in autonomy: change in participation in healthcare decision making and change in freedom of movement to seek healthcare, as reported by the married female respondents. Respondents were asked, "Has your participation in this decision [related to your own healthcare] increased, decreased, or not changed in the last 5 years?" Respondents were also asked "Do you think your freedom of movement in this respect [to visit a health clinic/hospital] has changed in the last five years?" Again, response options were: increased, decreased, and unchanged. We compare those who reported increased autonomy with those who reported decreased or unchanged autonomy.
In addition to changes in healthcare autonomy, current autonomy levels were measured by assessing self-reported participation in decision making and freedom of movement related to their own healthcare. Women were asked, "Who makes this decision [related to your healthcare]?" Very few women reported not participating in this decision at all. To capture the split between those who felt fully autonomous in the decision and those who considered the decision jointly with others, we categorized the responses as follows: making decisions alone; making decisions with others (if she reported making decisions with her husband or family elders, or that everyone in the household makes the decision); or not being involved in decisions at all (if she said husband alone or family elders alone make decisions). Women were also asked about their current freedom of mobility: "Can you go by yourself [to a health clinic/hospital]?" Response options included: yes; no, you need an escort; no, you are not allowed to go; and other. This is the first analysis that uses these measures of decision making and mobility in the KMS. However, similar measures have been used in analyses of women's autonomy; for instance, in a 2008 study using the India Human Development Survey (Desai & Banerji, 2008) and in analyses of the 1996 Matlab Health and Socio Economic Survey (Anderson & Eswaran, 2009). Both surveys include a corpus of questions about the extent to which women are involved in decisions and where they are able to move around on their own. Although the degree to which women report involvement in their decision making and freedom of movement represent tangible dimensions of autonomy, questions about whether women feel these dimensions have changed reflect their perceptions about their autonomy. Jointly, these measures capture a full picture of lived experiences for women in migrant households.

Remittances
To examine the effects of remittances from individuals outside of Kerala to women left behind, we use data from the migration module of the KMS household survey. In a remittance schedule, respondents were asked whether or not they received remittances in the form of money, goods, or gifts from persons residing abroad or within India in the past 12 months. If they responded yes, they were asked to list the individuals who sent and received each remittance, the frequency with which the remittance was received, and the amount received. They were offered six options to describe the remittance frequency: every month, every three months, every six months, every twelve months, no fixed pattern, and other. Data from other waves of the KMS household survey have been used to assess the impact of receiving remittances at all, as well as the impact of the amount received (Valatheeswaran & Imran Khan, 2018;K C Zachariah & Rajan, 2015). However, this is the first analysis that utilizes frequency measures from the remittance schedule and that uses remittance data from the 2016 wave of the KMS.
Households can list multiple remittances in the remittance schedule; this analysis focuses on the family's primary remittance: the remittance they list first. Thus, those who list a remittance received every month in the first line could receive remittances more frequently overall if there are multiple remitters. Among households included in the gender module, only 50 listed multiple remittances received, and there is a drop off in amount received after the first remittance listed.
We first assess the effect of a migrant household receiving any remittance, using a dichotomous variable allowing comparison between those in households receiving any amount of remittance with those in households that received nothing.
To examine the effects of remittance timing, we conduct two analyses: the first concerns pattern, comparing those who receive at least one patterned remittance (reflecting some sort of regularity) with those who receive remittances in no discernible pattern; the second concerns frequency, comparing those who receive remittances at different frequencies (every month, every three months, and every six months to one year).
To assess the impact of remittance regularity, we group all women who reported receiving their primary remittance in any fixed pattern-either every month, every three months, every six months, or every year-as receiving patterned remittances and compare them with those who reported no fixed pattern in receiving their remittances. To compare the impact of differences in remittance frequency, we include variables specifying how often the women receive remittances. Since the number of women who reported remittances every six months and every year were relatively small, we group those who received their primary remittance either every six months or every year into the category of "rare" remittances, comparing them with those who receive remittances every month and those who do so every three months.

Statistical analysis
We fit multivariate logistic regression models to analyze the relationships between remittance regularity and frequency and women's healthcare decision-making outcomes, as well as to analyze the relationships between remittance regularity and frequency and women's healthcare-related freedom of movement. For the regression analyses, we created dichotomous variables to represent women's healthcarerelated autonomy: increased and decreased/unchanged participation in decision making, and increased and decreased/unchanged freedom of movement. The same model was tested with alternative specifications-with different frequencies of remittances-to determine the interval that has the greatest impact on women's autonomy.
We control for household income, total amount of remittances received, respondent's age, respondent's employment status, husband's residence, and in-law residence, which are factors known to be related to women's autonomy. Self-reported household income and amount of remittances were collected in rupees and divided by 1000 for interpretability. We calculated annual household income by multiplying amount of income received in the month prior to the interview by 12. This figure included salaries, pensions, rental income, and business income and did not include remittances and other money received from outside Kerala. KMS staff calculated total remittances received in the past 12 months by summing the amount of remittances households received from various individuals. Respondents reported details on their economic activity, from which we categorized their employment status into four classes: not working, participating in unpaid labor, looking for work, and employed. Husband's residence was measured by responses to the question, "Does your husband currently reside in the household?" Lastly, we use household rosters with information on a respondent's relationship to the head of household to construct a dichotomous variable for whether or not the respondent resides with her in-laws. We categorize women as residing with their in-laws if the roster indicates that they are a daughter-in-law or sister-in-law in their household or if they are listed as wives in a household that also contains a parent. Table 1 in Results shows descriptive statistics for these covariates.
We fit additional multivariate logistic regression models to explore the effects of receiving remittances directly rather than through another household member. There are two possible ways to identify these women: the first is that respondents in the gender module who indicated they are receiving remittances are asked "Is the money being sent to you directly?"; the second is to match a respondents' identification number to the identification numbers listed in the remittance schedule under the recipient column. In the first set of models, we add a dichotomous indicator of their answer to whether money was sent to them directly as an additional control. In the second set, we restrict the sample to women who responded "yes" to that question. In the third, we restrict the sample to women whose participant identification number from the gender module matched a participant identification number that was reported as a remittance recipient in the remittance schedule. Like the regression models described above, the first model in each of these two sets estimates the association between remittance frequency and regularity on participation in decision making, and the second model in each set estimates the association between remittance frequency and regularity on freedom of movement to health centers. We again control for household income, total amount of remittances received, respondent's age, respondent's employment status, husband's residence, and in-law residence. Finally, our last set of regression models also estimate the association between remittance timing on health-related decision-making and movement, but instead of using the dataset with missing observations removed, these models use the full sample of women who completed the KMS gender module (n ¼ 2834).

Findings from the KMS survey
Healthcare autonomy levels (as recorded in 2016) are displayed in Table 1. More than 60% of women reported jointly making decisions about their own healthcare with others in the family, more than 35% reported making healthcare decisions on their own, and less than 2% reported not participating at all in decisions regarding their own healthcare. Although 70% of women reported being able to go to a clinic alone, many reported restrictions on their freedom of movement; 28% of respondents needed an escort to visit a health clinic or hospital. Table 1 also displays data on changes in healthcare autonomy between 2011 and 2016. When it came to decision making, 28.3% of women reported increased participation and 71.7% reported decreased or unchanged participation. Likewise, 29.5% of women reported increased freedom of movement and more than 70% reported decreased or unchanged freedom of movement. Figs. 2 and 3 display the relative odds of increased participation in healthcare decision making and increased freedom of movement as estimated by each regression model. Tables 2 and 3 present these regression models in greater detail. Our findings suggest that women who received patterned remittances reported increased autonomy compared with women who received remittances at irregular intervals, net of the amount received. Our findings also suggest that the highest odds of increased autonomy are among women who received monthly remittances, compared with women who received remittances at other frequencies. By contrast, merely receiving remittances is not significantly associated with increased autonomy.
After adjusting for household income, amount of remittances, age, employment status, whether or not the respondent's husband resides in the household, and whether or not the respondent lives with her in-laws, we found that the odds of increased participation in decision making among women who received at least one remittance compared with women who did not receive any remittances was not statistically significant (odds ratio [OR], 0.39; 95% confidence interval [CI], 0.10-1.52). Conversely, the associations between participation in decision making and timing of remittances (receipt of patterned remittances  Receiving remittances on any pattern is associated with increased freedom of movement to healthcare centers. Panel B: Those who receive remittances every month rather than every three, six, or twelve months are more likely to report increased freedom of movement to healthcare centers. and receipt of monthly remittances) were highly statistically significant. The odds of increased decision-making among women who received at least one patterned remittance were 2.94 (95% CI: 1.75, 5.16) times that of women who received remittances in no fixed pattern. The relative odds of increased participation were slightly higher among women who received remittances every month (OR, 3.11; 95% CI, 1.84, 5.51) than women who did not receive primary remittances in a fixed pattern.
The adjusted OR (aOR) of increased participation in decision making among women who received at least one remittance every month compared with women who received remittances at irregular intervals was 3.11 (95% CI, 1.84, 5.51); the aOR among women who received at least one remittance every three months was 1.91 (95% CI, 0.86, 4.26); and the adjusted odds ratio among women who received at least one rare remittance in a fixed pattern was 2.22 (95% CI, 0.75, 6.21). Fig. 3 displays the relative odds of increased freedom of movement to healthcare centers.
Similar to the relationship between remittance timing and decision making, we found that women who reported patterned remittances also reported increased freedom of movement to healthcare facilities. The strength of this association between remittance timing and autonomy increases as remittance payments are distributed more frequently. More specifically, we found that the more frequent the pattern of remittances, the higher the odds of increased mobility to healthcare facilities.
Notably, we also found that the relationship between remittance timing and self-reported freedom of movement is stronger than the relationship between remittance timing and participation in decision making.
After controlling for potential confounders, the association between merely receiving remittances and change in freedom of movement among women was not statistically significant (OR,0.89;95% CI,0.23,4.32). However, the odds of increased freedom of movement among women who received patterned remittances, remittances every month, and remittances every three months were 3.49 (95% CI, 2.02, 6.41), 3.74 (95% CI, 2.12, 7.01), and 3.55 (95% CI; 1.62, 8.03), respectively, compared with women who received irregular remittances; these associations were all statistically significant. Notably, after controlling for confounders such as amount of remittances received, the higher odds of increased freedom of movement among women who received patterned remittances compared with women who did not receive remittances in a fixed pattern suggest that timing of remittances drives the relationship between remittances and women's autonomy related to their own healthcare.
Our results are confirmed in additional regression models that are adjusted for receiving remittances directly or are restricted to women who receive remittances directly (presented in Supplemental Tables 1-6), as well as regression models that use the full KMS sample (presented in Supplemental Tables 7 and 8). When we examine only the sample of direct remittance recipients and add direct access as a control, the effects of remittance timing remain strong.
experience a higher sense of autonomy than those who do not. It also underscores the importance of considering the particular parties involved in remittance sending: not only who sends them but also who receives them. Our qualitative interviews reveal stark differences in women's access to remittances that are sent home on their behalf and the consequent affect on their autonomy. One woman who did not receive remittances directly told us that: Almost all of the money he sends home is used up for running the household. The money doesn't come to me-it comes into the bank account of his younger brother, who along with my mother-in-law uses it to meet household expenses. I have virtually no role when it comes to using the money my husband earns in the Gulf.
The woman above saw no benefits with respect to increased capacity for decision making or freedom of movement. Another woman who did not receive remittances directly said that: I had responsibilities in the family like cooking, cleaning, and helping father in cattle rearing (collecting grass, cleaning cattle shed) and also had to pay attention to my children's education. If I want to go outside for some matters, my mother-in-law would come with me or father-or brothers-in-law. I had not gone outside alone while my husband was away from me …. Father-in-law received the money/remittances and he used them to give me my needs.
In contrast, women who received funds directly experienced significant gains in autonomy of movement and over substantive decisions, especially if remittances were sent on a regular basis. One woman told us that: My husband sent money to his elder brother. He gave it to mother and she kept it. But now he is sending money to my account. It is for the last five years. I ask help/advice from his brothers and my family, when a serious matter I face. I asked their help when we were building the house and his brother used to come with me to banks. Now I go to the bank and take money from my account. Last year onwards, he was sending Rs 15,000 [approximately 210 USD] a month. Rs 5000 is the school fee of my daughter.
Remittance regularity is a central element in the narratives of women who were able to use their husbands' absence to increase, rather than decrease, their levels of autonomy over crucial decisions and to plan for the future, with respect to their children's education, their health-related decisions, or the construction of a new home, as in the case below: My husband sends home around Rs 20,000 [approximately 280 USD] per month, and he sends it into my bank account. I use some of the money to help meet the household expenses, and the rest goes into asset creation. We are planning to build a small house of our own here. We have already constructed the base for the house, and now we have a plan to go ahead and begin the actual construction of the structure.
In another woman's description of how she and her husband plan to use their remittances, we see how they try to deal with irregularity by Table 3 Logistic regression models estimating associations between remittance frequency and increased reported freedom of movement to health centers: Kerala migration Survey, 2016. Odds ratios (95% CI). Signif. codes: 0 '***' 0.001 '**' 0.01 '*' 0.05 '.' 0.1 ' ' 1.
seeking other sources of income: My husband sends the remittances into his own back account here in Kerala. However, I operate the account on his behalf, using presigned cheques to withdraw the cash necessary to run the household. The remittances are erratic in nature-we don't get them every month. Household expenses usually come to around Rs 3,000 [approximately 42 USD] every month, which we mete out these remittances. If there is any need for more money here, my husband borrows money from someone else and sends it so that we face no hardship.
These reflections on household management and future planning demonstrate that remittance timing has salience in the eyes of women in migrant households. The frequency with which husbands send money home is a salient part of their family's calculations and is meaningfully related to well-being for the women we interviewed.

Discussion
Our analysis suggests that migrant remittance sending can impact sending communities not only by boosting household wealth and economic development but also through its effects on the health autonomy of those left behind. Specifically, we find that remittance timing-rather than amount-drives the relationship between remittances and women's autonomy over their own healthcare. Using data from the KMS 2016 household survey, we examine the effects of remitting pattern and remittance amount, looking at both regularity (whether migrants remit on a fixed pattern or not) and frequency (how often they remit). The evidence shows that women left behind in migrant households were more likely to report an increase in their participation in healthcare decision making and an increase in their freedom of movement to seek healthcare when the household received remittances in a regular and frequent pattern. For an indicator of personal autonomy, we looked to women's responses to questions about their participation in decision making and their freedom of movement in health-related matters. In both cases, women were asked if their participation or freedom increased, decreased, or remained unchanged in the last five years.
Our models predict the impact of remittance timing-both pattern and frequency-on indicators of autonomy, controlling for household income, total amount of remittances received, respondent's age, respondent's employment status, husband's residence, and in-laws' residence. That the regularity of remittance sending is significantly associated with reports of increased participation in decision making and increased freedom of movement suggests to us that the study of economic transactions must look beyond questions of amount. Moreover, regularity matters, but not on just any time scale-even though annual and semi-annual remittances would constitute a "regular" remittance, they did not have the same positive associations with increases in autonomy as did more frequent remittances.
In contrast to expectations derived from the literature, living with inlaws did not emerge as a significant determinant of autonomy in our sample; although there is a slight negative association between living with one's in-laws and reporting increased autonomy, this association was not statistically significant. Women's employment is positively associated with increased autonomy, suggesting that there is sufficient social and economic opportunity for women in Kerala to be employed outside of the household. Yet the effect of employment outside of the home was not as strong as that of receiving regular and frequent remittances.
This pattern invites us to consider how remittance sending is as much a social interaction as an economic transaction. To entrust someone with your earnings suggests confidence in their plans and alignment of financial goals. In these ways, it is a subjective indicator of confidence in the independent decision making of the remittance recipients.
Moreover, a key component of autonomy is having the resources with which to enact one's plans. As our interviews demonstrate, remittances are often used to enact long-term plans, such as building a house, buying new land, or funding a child's education. Seeking healthcare is similarly a form of long-term planning. The decisions women make about preventative treatments, contraceptive use, or prenatal care involve intentions for their future. Part of planning for the future is having additional income at hand-but even more crucial is having the reasonable expectation that income will continue to arrive. Remittances that are regular and frequent impart and affirm expectations for future income. Women who receive remittances regularly and frequently have a firmer material foundation from which they can assert autonomy over decision making in the short and long terms. Interview data from Kerala suggest that this is particularly salient for women left behind who receive remittances directly rather than through a family member. Indeed, supplementary analysis of our survey data shows that the effects of pattern on increased autonomy are even stronger for women who receive remittances directly rather than through a family member (See Tables S1-S6), but finding these effects also among women who receive remittances indirectly indicates the high degree to which timing matters. With respect to their healthcare, the association between greater autonomy and better health outcomes for women is clear. When women have the capacity to plan and make choices about their own health, they and their children are healthier. Those concerned about women's health in the developing world should consider the dynamics of migration and remittance pattern. Because remittance patterns and frequencies are shaped by institutions in destination countries, changes that facilitate frequent remittances, net of overall volume, can make a difference for women's autonomy and health by making planning possible.
There are some limitations to this study. First, restricting our analysis to those in the gender module who are in remittance-receiving households notably reduces our sample size. In Models 4 and 5, applied to those receiving remittances every three or more months, the sample sizes are especially small, and the results of those models should be treated with caution. Limiting analysis to women who receive remittances directly further shrinks the sample. More power could be gained with a study that explicitly oversampled women who receive migrant remittances.
Second, although Kerala is in many ways an ideal study site, we should be cautious when extending these findings to other migrantsending communities. Kerala is particular for its density of migrant households and overall high levels of economic development and literacy. Research in other contexts has shown notable differences in the effects and uses of migrant remittances, even between urban and rural areas. Further, because measures of autonomy and empowerment are context specific, changes in healthcare decision making and freedom of movement to healthcare centers are not always an appropriate measure for health-related autonomy (Malhotra, Schuler, & Boender, 2002).
The KMS data also do not allow us to determine the time point at which migrants began sending remittances, relative to the changes in autonomy women reported. The question asks for changes women have experienced "within the past five years." Given that short-term contracts are likely between one and three years long, we can hazard that these changes are occurring on the same time scale as a single trip if there is presently a migrant sending remittances to the household. Yet we are unable to determine a causal relationship from a statistical standpoint.
Although the KMS does include information about migrants in the household, there is no way to determine the stability of migrants' employment during their time abroad. Thus, our analysis does not account for the possibility that unstable employment underlies the association between irregular remittances and lower autonomy for women left behind. However, the structure of migration to GCC countries requires all migrants to have full-time employment in the destination country. Even in cases where this is violated or employment falls through, there is little reason to believe a migrant's unstable employment should have a direct impact on a woman's healthcare autonomy, net of its effects on the regularity of remittances.
One could also argue for a reverse causality-that women who feel they are more autonomous are better able to elicit frequent and regular remittances from migrants. However, among women who reported increased, decreased, or unchanged autonomy, the proportion of those who had high levels of autonomy versus those with low levels of autonomy are almost identical. Additionally, there is no reason why the ability to elicit more regular remittances should be related to healthcare autonomy in particular.
Despite these limitations, our study shows that remittance timing matters, regardless of volume. This challenges the usual emphasis on remittance volume as the driving factor of social and behavioral change in sending community households. It asks us to refocus our analytical efforts on a better understanding of the social-interactional component of remittance sending and how these interactions can shift a woman's place within the social structures of the home. Just as crucially, the importance of remittance timing suggests that policy makers interested in the well-being of migrant families would do well to renew efforts to facilitate timely and reliable remittance transfers while migrants are abroad. Lastly, it invites us to expand our thinking about how male migration affects women left behind, beyond the conventional sorting into "economic" and "social" remittances, to how the structure of migrant-family interactions can impact sending communities in important ways.
