An Analysis of the Effects of Public Investment on Labor Demand through the Channel of Economic Growth with a Focus on Socio-Professional Categories and Gender

: The paper aims to analyze the impact of public investments generated by implementing the Emerging Senegal Plan (ESP) on economic growth and gender inequalities observed in the labor market in Senegal. A dynamic computable general equilibrium modeling was carried out for this purpose using a social accounting matrix (SAM) based on an extensive segmentation of the labor market according to gender and socio-professional category. The results prove that the investments made in priority market sectors led, overall, to a good trajectory of economic growth. Moreover, job creation followed the expansion of sectors of the economy, which increased their demand for labor because of the capital increase. In conclusion, there is a strong demand for qualiﬁed women (senior executives and middle executives). We recommend considering positive discrimination in favor of women by implementing public employment programs and the importance of recovery sectors affected by the pandemic.


Introduction
Since its independence in 1960, the Senegalese economy has always experienced erratic growth. It has known five significant phases of development: (1) The period 1960-1983 was marked by irregular growth.
(2) 1983-1994 is a period that corresponds to the exclusive recourse to internal adjustment, characterized by an investment deficit and a loss of growth and competitiveness. (3) The post-devaluation decade (1995)(1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005) was marked by the pursuit of reforms and the acceleration of growth. (4) The period 2005-2013 was characterized by a slowdown in economic growth. (5) The period after 2013 was characterized by an improvement and stability of growth.
Senegal has many advantages, including strong democratic stability likely to attract foreign direct investments (FDI), a geographical location allowing privileged access to European and American markets, significant diversification of its economic tissue; however, the country's economic performance is often fragile compared to the overall trend of sub-Saharan African countries (Chetboun 2015).
The Senegalese economy is confronted with structural problems that fundamentally influence its growth model: the inefficiency of public spending, difficulties in the energy sector, an unfavorable business climate, and insufficient and unproductive private investment. In this regard, the country has often relied on public investment to drive growth.
Since February 2014, public decision makers have implemented a new economic development strategy, the Emerging Senegal Plan (ESP), the medium-and long-term economic policy benchmark. Senegal's ambition through the ESP is to promote economic growth with The same trend can be observed in terms of the employment rate. Even if the employment rate of men is much higher than that for women, there was a slight increase in the rate of men from 53.6% in 2006 to 57.3% in 2018, while that of women markedly increased from 25.5% to 32.3% between 2006 and 2018 (see Figure 2). From the point of view of the unemployment rate, it should be noted that they developed differently. The unemployment rate for men rose from 7.7% in 2006 to 18% in 2013 and then gradually decreased to 7.4% in 2018 (ANSD 2013). On the other hand, the unemployment rate for women has seen an evolution sawtooth, although there has been a slight increase over the last three years, reaching 26% in 2018 (see Figure 3). The same trend can be observed in terms of the employment rate. Even if the employment rate of men is much higher than that for women, there was a slight increase in the rate of men from 53.6% in 2006 to 57.3% in 2018, while that of women markedly increased from 25.5% to 32.3% between 2006 and 2018 (see Figure 2). consider implementing public policies in the consolidation of the economic growth process and the fight against inequalities between men and women.

Brief Presentation of the Senegalese Labor Market According to Gender Disparities
Notable gender disparities characterize the Senegalese labor market due to men's and women's relatively different job opportunities (Sall 2018). These disparities are reflected in the analysis of activity rates, employment rates, and unemployment rates. From 2006 to 2018, the activity rate of men was significantly higher than that of women. The activity rate of men increased slightly from 66.6% to almost 70%, while that of women increased significantly from 36.9% to 50.6% (see Figure 1). The same trend can be observed in terms of the employment rate. Even if the employment rate of men is much higher than that for women, there was a slight increase in the rate of men from 53.6% in 2006 to 57.3% in 2018, while that of women markedly increased from 25.5% to 32.3% between 2006 and 2018 (see Figure 2). From the point of view of the unemployment rate, it should be noted that they developed differently. The unemployment rate for men rose from 7.7% in 2006 to 18% in 2013 and then gradually decreased to 7.4% in 2018 (ANSD 2013). On the other hand, the unemployment rate for women has seen an evolution sawtooth, although there has been a slight increase over the last three years, reaching 26% in 2018 (see Figure 3).

Literature Review
The first models of economic growth (Domar 1946;Harrod 1939) explained economic growth solely by the volume of investments. These models subsequently paved the way for modern growth models, as Solow (1956) introduced the concept of technical progress as a long-term exogenous growth factor and established the famous concept of convergence economic.
The hypothesis of technical progress and its exogenous aspect have been overturned by the contents of endogenous growth models, which consider that technical progress is not exogenous but somewhat produced (Burlea-Schiopoiu et al. 2017). Moreover, real economic growth is endogenous because it results from economic choice, optimizing agents, cumulative factor investments, including human capital, technology, physical capital, and public capital (Darreau 2003).
The advent of endogenous economic growth theories has accelerated the conceptual evolution of the growth process through the endogenization of technical progress through experience (Arrow 1962;Burlea-Schiopoiu 2009), research and development (Romer 1986), and education (Lucas 1988).
The theory that most attracts our attention concerning our research is Barro (1991), who insists on the link between public capital and economic growth. Indeed, according to this theory, public investment is one of the main determinants of economic growth. By emphasizing the features of public capital, Barro's theory highlights the imperfections of the market, which, beyond the existence of monopoly situations, are mainly linked to the problems of the appropriation of innovation. Public investments in infrastructure, education, and basic research are essential for sustainable economic growth (Goumrhar 2017).
In this context, it is up to the State to create institutional structures that support the profitability of private investments and subsidize activities that are insufficiently profitable for economic agents and yet essential to society. Public investment is considered a means of leading the economy towards economic growth with an improvement in the productive capacity and productivity of the different sectors of the economy (Costa-I-Font and Rodriguez-Oreggia 2005).
From the point of view of women's participation in the labor market, it must be mentioned that economists discuss this problem at length. For example, Akyuz and Dogan (2017) consider that both the level of development and the educational level are the most relevant variables to analyze the participation of women in the labor market. For most studies, the link between economic growth and women's activity rate is explained by a curve in the shape of a normal U (Tam 2011; Gaddis and Klasen 2014; Lechman and Kauer

From the point of view of women's participation in the labor market, it must be mentioned that economists discuss this problem at length. For example, Akyuz and Dogan (2017) consider that both the level of development and the educational level are the most relevant variables to analyze the participation of women in the labor market. For most studies, the link between economic growth and women's activity rate is explained by a curve in the shape of a normal U (Tam 2011;Gaddis and Klasen 2014;Lechman and Kauer 2015;Verme 2015;Azuh et al. 2017).
Using mostly MEGCs, these authors attempted to provide indications to justify the trajectory of the curve by referring to the theory of Boserup (1970). According to this theory, men's preferential access to education and new technologies can deprive women of jobs during the first years of economic growth. However, as economic growth improves, women have access to education and technology that later promote an increase in the female employment rate. Likewise, the authors have provided other explanations for the trajectory of the U-curve (Mammen and Christina 2000;Lincove 2008;Cavalcanti and Tavares 2011), which point out that at the very beginning with an agrarian economy, women were very present in the labor market. Then, they withdrew at the earliest stages of economic growth with the surge of the blue-collar sector and finally returned when the white-collar sector grew.
However, according to other authors, the women participation rate experiences an opposite trajectory. Thus, it increases at the start of economic growth to a maximum before decreasing (U-shaped curve inverted). For these authors, the participation of women in the labor market increases from the early stages of economic growth before decreasing from a ceiling (Tansel 2002;Fatima and Sultana 2009). These results reflect those of Casale and Posel (2005), who demonstrated a positive relationship between variables during the booms of the decade after apartheid in South Africa. Akyuz and Dogan (2017), drawing inspiration from the work of Kuznets (1955) and using the approach of the autoregressive distributed lag (ARDL) model of analysis, were able to prove that economic growth first increases the participation rate of women to a maximum level and finally, the trend is reversed.
Alongside these contradictory results, Lahoti and Swaminathan (2013) have shown, using a dynamic panel model, that there was no significant relationship between economic growth and the participation rate of women in working life in India during the period 1983-2010. Their results reveal that economic growth, by itself, is not sufficient to increase women's economic activity because the dynamics of growth are rather important. Gaddis and Klasen (2014) followed the Lahoti and Swaminathan (2013) approach with a sectoral one. They analyzed the effect of structural changes on the participation rate of women in the labor market using sectoral growth rates in developing countries. Using a dynamic panel model, they found that sectors such as agriculture, industry, mining, and services affect the employment rate of women differently. Their results show that structural changes have a weak effect on the participation rate of the female workforce. They concluded that the assumption of a U-shaped female participation rate in the development process is not too relevant for most developing countries. Moreover, it should be emphasized that the nature of this relationship also depends on cultural, religious, and/or behavioral specificities, which may vary from one country to another (Nassar 2003;Fernández 2013). By way of illustration, women in Muslim countries often do not have access to employment due to their religious constraints, and, in this case, a U-shaped relationship hypothesis with solid foundations might not be valid in these countries (Wolch and Dear 2014).
Finally, it should be emphasized that the most outstanding contemporary challenge for humanity is to promote economic and social policies capable not only of assuring inclusive growth but of controlling the dynamics of the labor market and of combating poverty by considering the inequalities that are observed there from all points of view (Azuh et al. 2017). Indeed, the labor market plays a significant role in implementing a virtuous circle between economic growth, poverty, and the reduction in inequalities. Therefore, the proper functioning of the labor market is a fundamental determinant of well-being and egalitarian development. Mansour and Tremblay (2018) put forward the need to propose a set of public policies (parental leave, childcare services, the flexibility of working hours) to consolidate economic growth and support women on the job market.

Computable General Equilibrium Model and Data
A dynamic computable general equilibrium model (CGEM)was built to simulate the impact of the ESP on the growth and evolution of the demand for labor according to gender. One of the specificities of this model is the integration of the channels through which public investments affect the total factor productivity of the different branches, proving the complementarity between private and public investments, the accumulation of capital, and the demand for labor. In the past, several general equilibrium models have been developed and applied in Senegal to analyze a wide range of policies (Boccanfuso et al. 2007;Cabral 2009Cabral , 2012Cabral , 2013. The choice of methodology is justified because general equilibrium modeling provides a more satisfactory answer than partial equilibrium analyzes by giving an overview of the channels through which the implementation of a policy passes (Suwa 1991). Thus, it makes it possible to analyze the impact of economic policies on the economy's structure in all its compartments concerning the interactions between sectors and between different economic agents.
As we previously mentioned, the basic model structure used was that of PEP-T, and we added an extensive segmentation of the labor market marked by the introduction of a wage curve and the modeling of foreign trade, which considers the existence of finite export demand. The model is dynamic recursive, which means that it is solved as a sequence of static equilibria connected over time through the accumulation of capital and the increase in labor and behavioral equations. One of the advantages of a dynamic model specification is the possibility of generating a medium-and long-term path, and structural changes can be analyzed over time. The model is for a small economy, for which world prices are given.

Parameters of the Functional Forms of the Model
The specification of the functions of production, household consumption, and import and export demands requires some parameters. The most important parameters are the following: the income elasticity of demand for products, the Frisch parameter, the elasticity of substitution between capital and labor, the elasticity of substitution between imported and local products, the elasticity of transformation between foreign and local sales, and the elasticity of foreign demand. In the absence of long series, these parameters were not estimated on data from Senegal. They were taken over from the literature and empirical studies in other developing economies (Annabi et al. 2006). All other model parameters were calibrated using SAM data to ensure consistency of base year data. The elasticity of complementarity between public and sectoral capital is taken from Cabral et al. (2017).

Accounting Framework of the Model: Social Accounting Matrix (SAM) of Senegal
The National Agency builds the initial matrix for Statistics and Demography based on the following tables: input-output table, the table of financial operations of the State, and the table of the balance of payments.
We disaggregated this matrix using the 2011 (ANSD 2011) statistics adjusted using the statistics from 2017 and 2018 (ANSD 2017;DPEE 2018). This matrix has been disaggregated as broadly as possible given the specificity of the research, and it includes 27 business sectors and 48 products. The labor factor was first segmented into ten socio-professional categories, as follows: • Senior executives and engineers (CSI); • Middle managers and supervisors (CMAM); • Employees and skilled workers (EOQ); • Employees and semi-skilled workers (EOSQ); • Employers; • The maneuvers; • Self-employed workers (own account); • Family helpers; • Paid or unpaid apprentices; • The others, which include the undeclared and the unclassifiable.
Therefore, each category of employees is also segmented according to gender (men and women). In total, the only labor factor is now found to be split into 20 sub-segments. Indeed, this segmentation makes it possible to highlight the heterogeneity of the labor market according to socio-professional category and gender to respond appropriately to the specificity of our problem. The capital factor is also split into two modalities: private capital and public capital. This segmentation procedure makes it possible to simulate the impact of a variation in public investments in a sector on employment according to gender and socio-professional category. Regarding agents, we have the classics: households, firms, government, and the rest of the world. To consider their heterogeneity, households are also dissociated into fifteen sub-segments according to income quartiles and living area (five quartiles for Dakar, five quartiles for other urban centers, and five quartiles for the rural area). The abbreviations correspond to the 27 sectors of activity found in the Senegalese economy (see Appendix A).

Justification of the Simulations
The simulation consists of analyzing the consequences of an increase in public investment in priority sectors, following the implementation of the first phase of the ESP (see Table 1. The choice of priority sectors emanates from public decision makers, and only market sectors were considered in the modeling. Implementing the first phase of the ESP resulted in a relative increase in public investment in the so-called priority sectors. The simulation consisted of varying the volume of public investment allocated to the group of priority sectors of the first phase of the ESP as follows: • Agriculture and agro-industry (in this sub-sector, the only increases in public investment are those noted in agriculture in the strict sense, and, consequently, the shock will only affect this sector); • Fishing-aquaculture; • Civil engineering roads-highways and ports-airports; • Digital economy (the telecommunications sector has been used here as a proxy). From 2014, the ESP resulted in an average increase in sectoral public investment between the sub-periods 2010-2013 and 2014-2016, as is presented in the following table (Table 1).
The model makes it possible to assess the effects of an increase in public investment allocated to sectors of activity on demand for labor and, therefore, the supply of jobs.

Results of Simulations and Discussions
After an analysis of the macroeconomic and sectoral impact of the shock linked to the increase in public investments in the so-called priority sectors, we analyzed the impact on the volume of jobs demanded by the sectors of the economy according to socio-professional category and gender, aware that in an EGC model, all variables interact and are determined simultaneously. In a dynamic model, the economy grows, even in the absence of a shock.

Global Impact on Production
The increase in public investment in the priority sectors of the ESP encouraged an increase in GDP and allowed an improvement in the growth rate of 1.28 to 3.02 percentage points between 2015 and 2018 (e.g., an average increase of 1.79 percentage points per year-see Figure 4).

Sector Impact on the Added Value on Production
Increased public investment is assumed to have relatively more impact in priority sectors with relatively higher public capital intensity. Consequently, the increase in public investments in priority sectors translated into an increase in their added value. The most significant increases were recorded in the mining and extract industries and other nonfood "autindna" industries. The other priority sectors (agriculture, fishing-aquaculture, civil engineering: road-highway, port-airport, digital economy: telecom) observed an increase in added value, but to a lesser extent ( Figure 5). Following a considerable increase in the flow of public investments, the return on public capital fell for the entire period, unlike that on private capital. We consider that the injection of public capital into priority sectors enabled them to develop and attract more private capital, and a spillover effect on public capital appeared ( Figure 6).

Note: CSI = senior executive and engineer; CMAM = middle manager and supervisor; EOQ = employee and skilled worker; EOSQ = employee and semi-skilled worker; Man = maneuver; Ind = independent; AF = family helpers; App = apprentice.

Impact on the Labor Market
We used the classification of the different socio-professional categories resulting from the Senegal documents (ANSD 2017), and to facilitate their analysis after the simulation process, we grouped the 20 segments of the labor market into four categories:  The highly qualified: Senior managers and engineers (CSI)/ middle managers and supervisors (CMAM);  Medium-skilled: Employees and skilled workers (EOQ)/ employees and semi-skilled workers (EOSQ);  The low-skilled: Employers/laborers/self-employed workers (own account);  The unqualified: Family helpers/paid or unpaid apprentices/others, which includes the undeclared and unclassifiable.
Our results prove that the increase in public investment caused an expansion of priority sectors but also of other sectors of the economy and, in turn, promoted a substantial increase in demand for the workforce (all segments included) except for self-employed men (Ind_H), who experienced a significant decrease in demand, and male family helpers who are practically observing the status quo ( Figure 6).

Our results prove that the increase in public investment caused an expansion of priority sectors but also of other sectors of the economy and, in turn, promoted a substantial increase in demand for the workforce (all segments included) except for self-employed men (Ind_H), who experienced a significant decrease in demand, and male family helpers who are practically observing the status quo ( Figure 6). This drop in the demand for work by self-employed men could be linked to a shift in demand towards other segments of the male workforce, particularly the skilled and medium-skilled segments. The sectors of the growing Senegalese economy prefer to free up self-employed men to fall back on other segments of more qualified workers. The same interpretation could be applied to male family helpers (AF_H), for whom the demand has stagnated, given that the economy already has a good stock of employees for this segment and that the demand for male labor is more oriented towards other socio-professional categories.
The results also prove, concerning the highly qualified segment, that women senior managers (CSI_F) are in greater demand than their male counterparts, and the same trend is observed for middle managers even if the difference is more negligible for this segment. From the point of view of the medium-skilled (skilled, semi-skilled employees and workers), the reverse can be observed with men, who are more in demand. As for the low-skilled (laborers), men are slightly more in demand than women are.
From the point of view of the unskilled employees, the results are a bit more mixed. While women caregivers are in greater demand than their men are counterparts, it is different for apprentices and other work segments (the undeclared and unclassifiable), where men are in greater demand than women are.
The analysis of work demand allows us to diagnose the evolution of wages, and we observed that the increase in labor demand led to an increase in wages for all work segments from 2015 to 2018. One exception was self-employed men, for whom wages logically fell over the entire period due to a drop in their employment request ( Table 2). The wages fell for many segments in 2015, which is linked to a delayed effect of the increase in labor demands on wages. Based on the results of our simulations, we noted a positive relationship between public investment and economic growth. Indeed, before implementing the ESP, Senegal had experienced very sober economic activity, given the low level of public investment. In this sense, the ESP has enabled an increase in public investment, which has resulted in a revival of economic activity and massive job creation.
This result confirms the theory of endogenous growth (Barro 1991;Goumrhar 2017) by emphasizing the existence of a positive correlation between public investment and economic growth. Senegal has made a lot of public investments in education, research, development, and infrastructure, among others, which has helped improve economic growth.
Public capital plays a driving role in economic activity in Senegal. In this sense, a significant increase in public investment, especially in infrastructure, makes it possible to attract private investors (local and foreign) and thus promote the recovery of the sectors concerned (Burlea-Schiopoiu et al. 2021). The results of our simulations show a complementarity and training effect between public and private investments (local and foreign).
From the point of view of foreign direct investment (FDI), it must be said that Senegal is one of the most attractive countries in the West African sub-region due to its socio-economic stability as well as the many advantages that the Senegalese economy has had since the implementation of the ESP. The latest UNCTAD report (2021) mentions that Senegal is among the few economies that will increase FDI flows in 2020. They are estimated at USD 1.5 billion due to mining, industry, energy, etc. Asada (2020) emphasized that FDI plays a remarkable role in the socio-economic development of countries, especially developing ones, and he pointed out that if most Asian countries have successfully integrated into the world economy, it is partly due to FDI.
In terms of the labor market, the results of our simulations show that the ESP has generally led to an increase in demand for labor. Indeed, the ESP has made it possible to improve the country's governance, strengthen resilience to external shocks and place the country on an inclusive and sustainable growth path, creating jobs for both men and women. These results agree with Casale and Posel's (2005) results from South Africa, with those of Fatima and Sultana (2009) from Pakistan, and with those of Akyuz and Dogan (2017) from Turkey. Our results are also not far from those of Asada (2020), who focused on foreign direct investments through the ARDL method and concluded that Vietnam developed its strategy to enhance the positive and constructive relationship between FDI, trade, and labor productivity. Asada (2020, p. 2) mentions that "The driving forces of the structural transformation include capital accumulation and technology transfer through FDI as well as the reallocation of labor from sectors with lower labor productivity to sectors with higher labor productivity, notably export-oriented manufacturing sector." From a gender perspective, it is generally observed that female labor is in greater demand for the highly skilled segment than male labor, while for the medium-skilled and low-skilled segments, men are more in demand than women are. This result is mainly linked to the low presence of highly qualified female labor in the Senegalese labor market, and female workforce scarcity means that it is in high demand in this market compared to the masculine workforce.
Notorious gender disparities still characterize Senegal regarding skill and productivity levels and a difference in human capital endowment between men and women. Inequalities are observed from college, where the trend shows that up to 78.9% of men reach the eighth year of higher education, while it is 21.1% for women. In addition, girls are poorly represented in the science and technology series (39.8%) compared to 60.2% for boys. Individuals with vocational training are 63.4% male compared to 36.6% female (ANSD 2017).
For the other labor market segments (the medium-skilled, the low-skilled, and the unskilled), it is generally noted that men are more in demand than women. This result is mainly related to the structure of the Senegalese labor market on the one hand and the choice of priority sectors of the ESP on the other. Thus, it is noted that the segments of the medium-skilled, low-skilled, and unskilled require physical capacity and a workforce that is generally more favorable to the male workforce.
The literature proves that starting from an expanding agrarian economy, the "bluecollar" sector (industry, mining, construction, etc.) is generally more favorable to male labor, while "white-collar workers" (service, banking, education, health, etc.) are more supportive of the female workforce (Lincove 2008;Cavalcanti and Tavares 2011). In this sense, given that the priority sectors of the ESP are predominantly in the sphere of 'bluecollar workers,' this is followed by the creation of more good jobs for men. Thus, to promote gender equality in the labor market, women's labor-intensive sectors ('white-collar' sectors) should be preferred. Antonopoulos and Kijong (2011), through a micro-simulation model applied to the Social Accounting Matrices of South Africa and the United States, demonstrated that investing in social services (for older people, people with chronic illnesses, preschool children, etc.) has a significant impact on job creation, especially for the female workforce. They concluded that investing in social services contributes to gender equality in the labor market and promotes income growth and inclusive development.
Our findings agree with those of Kim et al. (2019) that proved based on a macro-micro simulation model targets on social sectors that are intensive in female labor, and that it is possible to promote job creation more favorable to women to fight against gender disparities in the labor market and to achieve inclusive economic growth. Kim et al. (2019Kim et al. ( , p. 1213 underlined that "the economic policy makers that alleviating female labor supply restrictions can aggravate unemployment even further in the face of a general lack of jobs, low growth or jobless growth at best".

Conclusions and Policy Implications
The result of our research is the dynamic computable general equilibrium model used to assess the impact of the increase in public investment resulting from the implementation of the ESP on growth and employment. Given the specific nature of the research, an extensive segmentation of the labor market was carried out to highlight the heterogeneities of the labor factor according to gender and socio-professional categories. The simulations focused on the variation in the level of public investment devoted to priority sectors during phase one of the ESP implementation during the period 2014-2018.
The results of our research prove that the substantial investments drained by the implementation of the ESP have put the Senegalese economy on a dynamic trajectory of economic growth. As a result, job creation followed the expansion of economic sectors and increased demand for labor due to a capital increase. However, this demand has evolved differently depending on the socio-professional categories and gender.
Regarding the highly skilled segment, women are in greater demand than men, except this mostly accounts for self-employed and caregiver workers. The implementation of the ESP influenced the labor market, generating a strong demand for qualified women (senior and middle managers), independent women and family helpers. The other effect of ESP implementation consists of an increased demand for men (especially medium-skilled, skilled, semi-skilled, low-skilled and unskilled).
The demand for qualified women is very high on the labor market, but they are available in very limited numbers, unlike their male counterparts. Self-employed women are in greater demand than men. One source of this divergent demand (women-men) is the preponderance of the women-associated trades on the Senegalese labor market, while the men are required for productive jobs.
From the point of view of the implications of economic policies, it could be argued that the practice of positive discrimination in favor of women with the implementation of public employment programs considering the gender dimension and the recovery of intensive sectors in traditional female labor (social sectors, education, daycare, hotel industry, tourism, catering, etc.) would make it possible to improve the employment rate of women in the short term.
The practice of positive discrimination in the favor of women with the implementation of public employment programs considers the gender dimension and the recovery of sectors accessible to women (e.g., hotels, tourism). Thus, in the short term, it would make it possible to improve the employment rate of women. In the medium to long term, by promoting women's education, retaining girls in schools, and encouraging them to take more interest in training, modern jobs based on science and technology would be relevant to facilitate skilled female employment.
In the medium to long term, the pursuit of raising the level of the human capital of women by promoting the education and retention of girls in school and by encouraging them to take more interest in training and modern jobs focused on science and technology would help facilitate their access to the skilled segment to find decent employment.
Moreover, it is essential to mention that if the computable general equilibrium models are powerful instruments for simulating the expected effects of a shock, the results can only be apprehended based on the assumptions which underline them. Indeed, when sterilizing all the other shocks to isolate the only effects attributable to the simulated shock, the impact assessment should only be interpreted through the prism of a comparison between a usual scenario without shock (business as usual) and the scenarios relating to the ESP.
Another limitation of this research is inherent to the accounting base used (ANSD 2011(ANSD , 2013(ANSD , 2017DPEE 2018), which we found to be a little old, mainly due to the unavailability of a newer base.
This research offers many perspectives, particularly the possibility of integrating women's domestic work (unpaid work) into the analysis and seeing the influence of this on-demand for women's labor at the labor market-paid employment level.
