The Effect of Business Legal Form on the Perception of COVID-19-Related Disruptions by Households Running a Business

: Recent studies uncover the lack of symmetry in COVID-19-related economic shock distri-butions among households. Thus, questions arise about the appropriateness of diverse risk-coping mechanisms by households. We add to this strand of research by focusing on households running a business. In particular, we analyze the role of basic legal aspects of running a business by individuals, speciﬁcally a legal form of business activity in shaping COVID-19-related business risk perception. We posit that the different legal forms allow for different risk-coping mechanisms. We incorporate analysis of variance (ANOVA) on data obtained via a survey distributed among households running a business in Poland, a country where the pandemic threatens poverty-reducing growth. We conﬁrm that between the groups of households running a business in various legal forms, there are statistically signiﬁcant differences regarding the impact of COVID-19. Thus, we conclude that the choice of business legal form affects vulnerability to COVID-19-related interruptions among households running a business.


Introduction
The COVID-19 outbreak has led to human tragedies, lockdowns and substantial disruptions to economic activities around the world. In this term the pandemic has generated a complex exogenous economic shock that has severely affected households. Personal financial damage is highly asymmetric which raises questions on how to design relief and recovery measures by policymakers and how to support household resilience in case of pandemic longevity. Household finance anchored studies provide in-depth insights into how severely COVID-19 impacts households' spending, income, wealth, investment and poverty (Hanspal et al. 2020a;Baker et al. 2020;Martin et al. 2020;Chronopoulos et al. 2020). There are also studies that aim to answer the question on which groups of households were more or less vulnerable to the pandemic shock. Barrafrem et al. (2020) show that contextual factors and personal aspects shape the financial vulnerability of households during the turbulent and stressful times of the pandemic. Other studies show that the current crisis is predominantly affecting low-income households, labor-dependent households, females and the unemployed (Brewer and Gardiner 2020;Schneider et al. 2020;Albacete et al. 2021;Kansiime et al. 2021). There is also important evidence that the level of vulnerability is unevenly distributed across countries (Midões and Seré 2021). A broad conclusion that can be derived from this emerging literature is that different individuals and households have been exposed to the COVID-19 driven crisis in different ways and to varying degrees, confirming the lack of symmetry in shock distribution and the change in inequality structures that the shock has introduced. However, in the extant literature, household heterogeneity has not been fully accounted for and further studies are needed to effects on diverse business legal forms. In this regard, our focus on the role of the legal form on the business activity undertaken by individuals can bring about a new understanding of the patterns of households' exposition to  In a methodical context, this study presents survey results. The survey was conducted in January-February 2021 on a random sample of Polish businesses, owned by households. In the period that we ran the survey, Poland was affected by the hit of the second wave of the pandemic. Thus, the surveyed household businesses were aware of the COVID-19 disruptions. They managed to familiarize themselves with these disruptions and they increased their awareness of direct and indirect impacts. We designed a questionnaire based on the previous COVID-19 survey-based barometers (Deloitte 2020;PwC 2020), aiming to capture the most important impacts that COVID-19 had on firms, including impacts on: costs, production and sales, liquidity, financing, overall threat and elasticity to react.
This study is organized as follows. In Section 2 we provide a description of business legal forms in Poland, the mechanisms of coping with the risk that a household may adopt and the related hypothesis. In Section 3 we present our research design, sample and method. In Section 4 we present our results which we discuss then in Section 5.

Business Legal Form as a Factor of Vulnerability
In the economics and management literature there is a separate strand that is focused on constraints and opportunities relating to small ventures' resilience and their growth in a turbulent environment. In this literature, scholars adopt three general perspectives on the types of factors that can determine such resilience: 1.
Our study focuses on an under researched problem of the role of a legal form, which relates to two types of above-mentioned factors: organizational (financing resources and their management) and institutional ones (law). We focus on three types of legal forms which are used to set up a venture by individuals in Poland: sole proprietorship (hereafter SP), general partnership (hereafter GP) and limited liability companies (hereafter LLC). Individuals setting up a business consider all three types of business legal forms, and they can relatively easily switch from one form to another, including LLCs.
The simplest form of business is the SP form, which is based on the single ownership of a firm. SPs can be easily founded by an individual and the owner (sole or single trader) is fully liable for debts and their liability is unlimited. This responsibility also extends to the spouse (excluding their personal property). The important feature of SPs concerning resources management is that private (also family) resources can be at any moment employed in a business venture and that business-related assets can be easily and immediately used for private purposes. There is no minimum initial capital that needs to be provided to set up a business. However, it is difficult to raise large amounts of capital as a sole trader. Thus, SPs may face financing constraints to a much bigger extent than other business legal forms. This capital gap may hamper their ability to survive in times of crisis.
Like in the case of an SP form, a GP form does not have a legal personality. This means that a GP form is not subject to the regulations concerning legal persons. It can be founded by individuals, as well as legal entities, who become partners. Rights acquired under the name of a GP and contracted liabilities become the rights and obligations of the partners of the company, who are jointly and severally liable for them. All the partners are responsible for all debts and obligations of a GP-not only with the company's property, but also with the personal property. In Poland a GP is perceived as a less risky form of business than an SP, because the partnership's liabilities are firstly repaid from its assets (Winnicka-Popczyk 2014). Any enforcement from the assets of a partner is viable if enforcement from the assets of the partnership proves ineffective (this solution is called subsidiary liability of a partner). However, in fact this does not protect a partner from being sued before the enforcement of the partnership's assets has proved to be unsuccessful. Thus, although the business risk may be spread proportionally to the equity holdings of partners, the perception of a GP as less risky than an SP may stem from partners sharing responsibility rather than from a lower probability of exposing personal wealth to the enforcement According to the Polish law regulations, there are no minimum requirements for the initial capital. However, the amount of capital that can be raised by a GP depends on the joint value of partners' personal assets, thus GPs face smaller capital constraints than the sole proprietorships (SPs).
An LLC in Poland can be launched by individuals as well as by the legal persons. The risk is limited only to the partners' contribution (no liability with personal assets), thus partners may fully control their risk exposure. In order to establish the LLC, a minimal initial capital of PLN 5000 is required (around EUR 230). Such a requirement for a very low initial capital should not be perceived as a barrier to set up an LLC by individuals. The limited liability of partners as well as higher financial transparency makes it easier to obtain external funding. For this reason, incorporated firms grow faster than unincorporated firms (SP or GP) (Harhoff et al. (1998)).

Risk Coping Mechanisms Influencing Households' Perceptions of Risk
Household vulnerability to shocks, and consequently their risk perception, depends on the configuration of risk-coping mechanisms adopted by a household. Well-recognized risk-coping mechanisms used by households include savings, borrowing, formal insurance, network referral, social protection system, or diverse mechanisms for sharing risks (Lee et al. 2010;Munshi 2003;Smith and Frankenberger 2018;Hallegatte 2014). In this section we focus on two types of mechanisms: the risk sharing and risk-limiting. The reason behind this is that different types of business legal forms used by households to set up a firm allow for different levels of risk sharing and risk limiting.
Informal risk sharing by households means that losses of each member of a particular group are allocated within the group based on social ties rather than contractual agreements. In general, two types of such risk-sharing are distinguished in the literature. First is intrahousehold (or within-household), which refers to joint decision-making by the single household members facing risk. Second is the inter-household risk-sharing, where larger communities of households take part in risk-sharing and that acts as a supplement to self-insurance via precautionary savings. It is well evidenced that intra-household risk sharing is commonly practiced and leads to the desired outcomes, e.g., lower vulnerability of households to sudden unemployment, income losses and cyclicality (Haan and Victoria 2017;Mankart and Oikonomou 2017;Wang 2019). Intra-household risk-sharing seems to be an obvious solution in face of a turbulent environment due to close ties among household-members, smooth communication and goal sharing.
Inter-household risk sharing refers to the ability of households to protect their consumption by relying on friends and the extended family, through community-level networks, and thereby to share the risk of volatile income and spending with others. It simply means that negative shocks can be covered by transfers and gifts from family and friends. Although inter-household risk sharing may appear to be a less viable solution than an intra-household risk sharing, its underlying mechanisms are solid and include extended family ties, altruism, social norms and reciprocity within broader social networks (Agarwal and Horowitz 2002;Bourlès et al. 2021;Fafchamps 2011). In addition, the evidence on interhousehold risk sharing is vast. In an empirical study of the rural Philippines, Fafchamps and Lund (2003) find that inter-household risk sharing takes place through networks of relatives and friends. De Weerdt and Dercon (2006) find that in Tanzania shocks to non-food consumption are smoothed via social-networks risk sharing. Gertler and Gruber (2002) observe that in Indonesia informal insurance helps finance the expenditure needs of individuals who suffer negative health shock. For Nigeria it is evidenced that, where savings are rare, households with informal financial access (inter-household risk sharing), which Risks 2022, 10, 82 5 of 17 experience unexpected negative income shock see consumption fall by 15% less than those without access (Carlson et al. 2015). One broad conclusion is that social networks of family and friends provide noticeable protection to individuals in an uncertain environment.
Since pooling and diversifying risk is a central function of the financial system, it is not surprising that many studies find that informal risk sharing is especially important in contexts where financial markets and insurance markets are under-developed (Fafchamps and Lund 2003;Yang and Choi 2007;Jack and Suri 2014). This effect is explained as informal risk-sharing mechanisms acting as a substitute or complementary mechanisms to formal ones (Krueger 1999;Tchamyou 2019). In this vein, Asdrubali et al. (2020) present an interesting finding that during the financial crisis in Italy, inter-household risk sharing could also be observed. Thus, not only the level of financial system development, but also the cyclicality of the financial system can determine the extent to which the households rely on informal risk-sharing mechanisms. The evidence provided by Asdrubali et al. (2020) is momentous because since the beginning of the pandemic credit markets have tightened and it is potentially more difficult for households to access new credit now than before the pandemic (Armantier et al. 2020;Horvath et al. 2021). In addition, in Poland the negative effect of COVID-19 on the banking sector resulted in the lower availability of bank loans (Łasak 2020). The tightening of credit supply and the flight-to-safety response of banks may exacerbate the role of risk-sharing among households during the pandemic. This includes households running a business.
Different types of risk sharing options are available for different business legal forms. Intra-household risk sharing is certainly practiced by SPs. Sole traders' family members' (e.g., spouses', children's, parents') property can be easily employed in the business activities as an informal source of financing and it can substitute credit from the constrained financial system and act as an elastic cushion against the increase of operating costs. However, it has a limited effect concerning households" property size. In GPs and LLCs, business owners can also use their family members' wealth inter-household risk sharing, but a co-owned business is acknowledged as a channel of inter-household risk sharing. In the GPs, any use of the personal wealth of partners for business purposes is very elastic. In LLCs, partners can reach out their personal wealth and raise additional equity to support businesses in trouble. It is claimed that since partners pool resources together to create a business, their households share business risk (Fafchamps 2011). Consequently, the wealth of several households can be used to absorb negative shocks. In this case business risks are pooled among partners and their households which results in the overall reduction of each partner's risk exposure (Attanasio et al. 2012).
Although risk-sharing mechanisms noticeably protect households, there can be cases where mechanisms other than risk-sharing are more viable solutions. Adopting risk-sharing mechanisms by the business owners requires decisions on allocation of resources among their household members. Using private wealth as a business risk absorbing cushion reduces the amount of wealth that can be used for other purposes and by household members other than the business owners. In Becker's (1965) famous extension of the neoclassical model of the household, all members of the household are assumed to jointly maximize some household level welfare function. In this model various types of time (good A) and consumption (good B) combine into a single household objective function with a single overall budget constraint. In this case the household is maximizing a single utility function and so it behaves in ways that are empirically indistinguishable from the behavior of a single utility maximizing individual (Thomas 1990;Chiappori and Lewbel 2015). Translating this famous model into the context of business risk management by households, one would say that households derive utility from their ability to absorb business risk shocks (intra-household risk sharing) and this substitutes for the utility a household can derive from using wealth for other purposes (e.g., consumption). Thus, each household would have a different acceptable level of within household risk-sharing depending on a particular substitution margin. The important thing is, diminishing marginal rates of substitution results in households being less and less willing to give up consumption in Risks 2022, 10, 82 6 of 17 order to absorb rising business risk. Knowing their rates of substitutions, households would put a limit on their wealth exposure to business risk at a level that maximizes their utility from wealth used for both purposes of business risk absorption and consumption. Limiting risk as a risk-coping mechanism may thus be a valuable option for households. In practice, setting a limit on a business risk exposure is possible for LLCs where partners are held responsible for their business liabilities up to the amount of their capital invested in a company. This amount is freely decided on by each partner and can be perfectly adjusted to the level where individual utility of wealth is maximized. Formal risk limiting is impossible for SPs and GPs.
It should be stressed that in the literature there are many doubts around Becker's model. The reason is that the internal logic of such a model obscures the significance of the intra-household dynamic (collective choices) and heterogeneity in preferences among household members (Evans 1991;Alderman et al. 1995). Since risk-taking is a collective choice, groups (household members) are required to reach a consensus on a single collective action (Davis et al. 1992). Consensus comes at a cost (Zhang et al. 2019) and it cannot be constantly renegotiated concerning household budgetary constraints. In addition, once a consensus is reached, the household members having heterogeneous preferences may use it as a reference point for their individual choices. Considering that the reference-dependent preferences are strongly evidenced as predictors of an individual's behavior (Crawford and Meng 2011;Abeler et al. 2011), a consensus on the within-household risk-sharing limit is an important element of heterogeneous household members' decision taking. Such consensus can be expressed as an amount of equity provided from private wealth to the LLC, further constituting a risk limit that remains unchanged until households decide to reduce or increase their exposure to business risk. Such solutions are unavailable for the households running a business as SPs or GPs. Thus, despite arguments against Becker's model, the risk-limiting should be perceived as an important risk-coping mechanism for households.
Business legal forms differ with respect to risk-sharing and risk-limiting possibilities. SPs allow for inter-house risk sharing. GPs and LLCs allow for inter-and intra-house risk sharing. LLCs above all allow for risk limiting. The three risk-coping mechanisms may provide different levels of protection for households running a business in Poland in times of COVID-19. Thus, we hypothesize that: Hypothesis 1 (H1). Sole traders (SPs), general partnerships (GPs) and limited liability companies (LLCs) differ in their perception of the severity of COVID-19-related interruptions.

Survey Design
The first cases of the COVID-19 infections were officially confirmed in Poland on the 4 March 2020, and shortly after the first lockdown was announced. This has led to the worsening of the macroeconomic conditions in Poland, as well as to the deterioration of the financial results of Polish enterprises. The survey was run when many household firms had already been closed for over a year and were able to operate on a regular basis only within short periods. From the macroeconomic perspective, the negative impact of COVID-19 on the Polish economy is manifested for instance by the decrease in GDP (4.6%) or reduced rate of investments (10.6%) (Ministerstwo Rozwoju 2020; data for the first quarter of 2020, in comparison to the third quarter of 2019).
Inspired by the COVID-19 barometer surveys (Deloitte 2020; PwC 2020), our survey consists of several sections, where the central issues were the COVID-19 disruptions. The surveys also addressed the size of the businesses and their age.
The data were collected by the university research agency that supervised the design of the survey and organized the pilot testing of the questionnaire. The survey was distributed online, among 5005 randomly selected household businesses located in Poland. In total, 627 completed surveys were received, but 89 were excluded from the analysis (large firms, with employment over 250 persons). Based on this, we obtained a satisfactory response rate of 12.53%.
In the survey design, we have focused on the selected COVID-19 impacts, guided by the existing COVID-19 monitoring surveys. However, the channels of interruptions that we monitored are also relatively obvious, if we consider the operating activity of any type of the business. The first set of questions addressed the interruptions that were direct in nature. We addressed: limited availability of workers (a natural consequence of the growing number of infections and imposed quarantines) and additional costs (due to the implementation of the required safety measures, e.g., disinfection or the measures of workers' protection).
Then, we considered issues that refer to financial performance and are induced by the inability to operate due to the lockdown. These covered: disruptions in supply chains and ability to continue production and sales. In our survey we also asked the respondents whether they noted the worsening of financial liquidity or faced some restrictions in the availability of funding. We also included one general question on the perception of the threat of survival (see Table 1). For each disruptive factor considered in the survey design, the respondents were asked to answer the question "Did the COVID-19 pandemic result in difficulties in the following aspects of the firm's performance?". We used a seven-point Likert scale, ranging from 1 (strongly disagree) to 7 (strongly agree).

Sample Composition: Businesses Characteristics
In Table 2 we provide the sample characteristics-the businesses ownership structure, size and age. Sole proprietorships (SPs) composed 36% of our sample. General partnerships (GPs) comprised 14% of our sample. Limited liability companies (LLCs) accounted for 50% of our sample. Thus, the sample was rather imbalanced if we consider the percentage of firms where the risk is shared among household members (SPs-36%) and businesses where risk-sharing is limited (GPs and LLCs-64%). However, the sample was fully balanced if we consider firms with unlimited legal liability and the related full owner's financial responsibility (SPs and GPs-50%) and those where this responsibility is isolated (LLCs-50%). Thus, the sample is balanced with respect to the share of risk sharing and risk limiting businesses. The sample structure does not reflect the structure of businesses operating in Poland regarding business legal form. In Poland 78% of businesses are SPs, 8% are GPs and 12% are LLCs (GUS 2021b). However, this is not relevant for the results, as we aim to understand differences between the types of business forms, not to make any conclusions regarding the whole population of businesses operating in Poland. In this context, balance between groups exhibiting differences is more important and this balance has been achieved. Our sample was relatively balanced if we consider the size of the surveyed businesses. In total, 39% of our sample were small firms (10-49 employees), 34% were micro firms (up to nine employees) and 27% were medium firms (50-249 employees). The sample was also relatively balanced if the age of the surveyed firms is considered. As for firms in their infancy, we classified 16% of respondents. The young firms composed 25% of our sample, whereas the intermediate firms comprised35%. The mature firms (that have operated for more than 21 years) composed 24% of the respondents.

Method
Our research hypothesis states that the businesses that operate in various legal forms differ in their perceptions of the COVID-19 disruptions. Accordingly, in the empirical analysis we apply the non-parametric ANOVA to verify the statistical significance of the differences in COVID-19 perceptions between the groups (Armstrong and Hilton 2011). In other words, in our empirical study the groups are the businesses of the defined legal form (which we interpret in the context of risk-sharing or risk-limiting among the households that run a business). We employed the non-parametric ANOVA (Kruskal-Wallis test and the related pair-wise comparisons), as the variables obtained in the survey are not normally distributed (see Appendix A, Table A1) and thus cannot be subject to parametric analysis (Armstrong and Hilton 2011;Van Hecke 2012). To support the conclusions we draw, we also performed the analysis of contingencies (Chi-squared test in Appendix A Table A2 and the related contingency ratios). We also refer to descriptive statistics (Appendix A, Table A3), to better highlight the observed differences between the businesses of the legal form of our interests.

Results
In Figure 1 we present the mean values of the analyzed COVID-19 interruptions by the type of the legal form of the business. As can be seen in Figure 1, in the case of interruptions related to costs, liquidity, bank loans and overall threat of survival, the surveyed SPs assigned visibly higher rates than the remaining types of businesses (LLCs or GPs). This observation is confirmed by the analysis of the contingencies, as the Chi-squared test and the related contingency ratios (Phi, Cramer's V or contingency ratio) are statistically significant in each case (Table 3).

In Figure 1 we present the mean values of the analyzed COVID-19 interruptions by the type of the legal form of the business.

This observation is confirmed by the analysis of the contingencies, as the Chi-squared test and the related contingency ratios (Phi, Cramer's V or contingency ratio) are statistically significant in each case (Table 3).  The results of non-parametric ANOVA indicate an interesting pattern. We find evidence that the businesses operating in particular legal forms differed in their perceptions of the COVID-19 interruptions. These differences were statistically significant in the case of the increase in operating costs, ability to continue sales, worsening of financial liquidity, access to bank loans and the overall threat for the businesses' survival. All these variables are directly linked to businesses' financial performance or capital constraints. There are no statistically significant differences for the disruptions in the limited accessibility of workers, continuity of production or the problems to maintain supply chains. This suggests that these interruptive mechanisms have equally influenced households' firms, regardless of their legal form that approximates risk coping mechanisms adopted by their owners.
In Table 4 we also present the pair-wise comparisons (an element of Kruskal-Wallis test) for these COVID-19 interruptions that we found statistically significant. In other   The results of non-parametric ANOVA indicate an interesting pattern.

In Table 4 we also present the pair-wise comparisons (an element of Kruskal-Wallis test) for these COVID-19 interruptions that we found statistically significant. In other words, we compare which particular legal forms of businesses differ with statistical significance. Data provided in Table 4 clearly indicate that in the case of four channels of interruptions there are significant differences between SPs and other types of business legal forms (GPs and LLCs). Only for the differences in the perceptions of continuity of sales, SPs did not differ at statistically significant level from GPs. The study of the mean ranks of the Kruskal-Wallis test, provided in Table 5, indicates that in each case SPs were perceived as the given type of COVID-19 factor which was more interruptive, in comparison to LLCs or GPs. This confirms the initial observation of mean values of assigned ranks, presented in Figure 1.  We also observed that the mean ranks of the Kruskal-Wallis test for GPs are lower than for SPs, but higher than for LLCs. This means that GPs perceived these interruptions as more problematic than LLCs. However, these differences are not statistically significant, as indicated by the pair-wise comparisons presented in Table 4.

Discussion
The results of non-parametric ANOVA focused on businesses' perception of diverse types COVID-19-related interruptions, allowed us to set up an interesting discussion platform. Our hypothesis stated that COVID-19 interruptions are perceived in different ways by SPs, GPs, and LLCs. This hypothesis finds some support if we consider particular channels of interruptions. SPs, GPs and LLCs differed statistically significantly if we consider their perceptions of the severity of interruptions caused by an increase in costs, continuity of sales, worsening of financial liquidity, accessibility of bank loans and the overall threat to their survival. In the in case of interruptions related to the limited accessibility of workers, ability to continue production and supply chain problems, there were no statistically significant differences between businesses operating in different legal forms. This pattern is very interesting. It indicates that the set of risks for which business legal form seem to be irrelevant and includes risks which need to be managed with physical risk control tools, rather financial risk control tools. In fact, access to financial resources can help manage workers' availability, possibility to continue production and supply chain disruptions only to a limited extent, especially in terms of COVID-19 specific risks. Paying higher wages will not help to safeguard employees when they need or want to protect their health. Acquiring additional means of production will not allow businesses to continue technological processes when technological lines need to be disinfected often or when workers are absent. Paying higher prices for suppliers will not maintain supply continuity when suppliers cannot operate due to lack of workers or locking down their factories.
On the other hand, a set of risks for which business form appears to be important in shaping business sensitivity to COVID-19, includes risks for which financial buffering is an efficient way of control. Increase in operating costs, as well as disruption of sales, both reduce gross margins and may push a business into illiquidity, unless access to financing allows it to withstand lower or even negative gross margins. Interruptions related to payment of receivables and liquidity, can also be smoothed by financial buffering.
Alternative sources of financing (reserves of funds, recapitalization by owners, loans provided by owners or family and friends) are a primary substitute for limited bank loan availability during economic crises. Finally, the overall threat of survival is related to the ability to raise and maintain capital. In other words, we find that some risks are perceived as similar for household businesses, regardless of their legal form. At the same time, some risks are perceived as more or less severe, depending on the legal form of the household business. Thus, these findings show that risk-sharing and risk-limiting mechanisms are relevant in managing only those risks that can be easily financially buffered. For other types of risks related to COVID-19, other mechanisms of risk management might be necessary. This requires further research focused on other properties of households running businesses.
The mean ranks of the Kruskal-Wallis test show that channels of interruptions have an unequal impact on businesses operating in different legal forms. Our results revealed that partnerships perceive the majority of these disruptions as less severe than sole proprietorships (which strongly supports our hypothesis). It means that risk-sharing is an efficient mechanism for managing a set of COVID-19-related risks by households running a business. This finding has important theoretical and practical implications. Theoretical implications are primarily related to whether and how social ties and close networking complement the financial market. Our results confirm that risk-sharing between households efficiently reduces business perception of risks related to exogenous shock accompanied by a tightening of credit supply. Thus, our results are in line with studies pointing to the important role of informal risk-sharing mechanisms acting as complementary mechanisms to financial services (Fafchamps and Lund 2003;Yang and Choi 2007;Jack and Suri 2014;Asdrubali et al. 2020). The theoretical implication of this finding is related to the capacity of social networks to reduce inefficiencies in the financial market. One clue for a more detailed understanding of our results can be that small businesses are perceived by banks as riskier and more informational opaque (asymmetry of information issue) (Dierkes et al. 2013). This asymmetry has been exacerbated in times of the COVID-19 pandemic and is perceived as a primary reason for "flight to safety" by banks (Corbet et al. 2020;Krukowski and DeTienne 2021;. Lin et al. (2009) report that stronger social ties, where social and economic relations intertwine with each other, alleviate the information asymmetry between borrowers and lenders. Following these notions, our results support that informal risk financing mechanisms and the related better access to financing by businesses which operate within strong social networks may do so by outpacing formal-ones, while resolving the asymmetry of information during COVID-19. This effect should be examined in-depth with further qualitative studies. Our results are also in line with a broader stream of research that suggests that social ties and social networks are increasingly becoming the basis of business processes (Burchardi and Hassan 2013;Carter et al. 2007;Neumeyer and Santos 2018;Dost et al. 2019).
Our results also revealed that LLCs perceive the majority of these disruptions as less severe than GPs and SPs (which provides strong support for our hypothesis). This suggests that risk-limiting is a mechanism that allows one to efficiently lower concerns over COVID-19-related interruptions. This finding has an important practical implication. Many households setting up a business have chosen SP or GP as their legal form due to the simplicity of management and the lack of capital requirements for running the business in these legal forms. Our results argue that these households should be better informed about the value of risk-limiting available under LLCs and educated about the cases where the risk-limiting options outweigh the benefits of simplicity and lack of capital requirements.
Another important theoretical implication of our study stems from revealing that different types of risk management mechanisms are of different importance for reducing business risk perception in front of diverse threats. In the case of disruptions related to costs, liquidity, bank loans availability and overall threat of survival, risk sharing helps to reduce respondents' concerns, while risk limiting does not. We also found that risk-limiting is a valuable option for venturesome households in the case of managing risks related to continuity of sales (partial support for the hypothesis). This conclusion is driven by the observation that LLCs perceived their anxieties about continuity of sales as significantly lower than both SPs and GPs. This could be driven by the long-term effects of interruptions on continuity of sales. For a business, it takes more time and effort to rebuild one's market position compared to finding additional sources of financing in order to protect against illiquidity, increase of costs and tightening of bank loan supply (and thus market risk is considered as strategic risk, as pointed by (Rowland et al. 2019)). In fact, market risk is perceived as posing a greater threat to small and medium size businesses, in comparison to financial risk (Kozubíková et al. 2015). Thus, putting a cap on this type of risk seems to be a desirable option for households owning a business venture. This suggests that risk limiting is better suited to manage the long-term risk of survival, while risk sharing is better suited to manage the short-term risk of survival.
Our results have important policy and managerial implications. Policy implications are related to supporting business networking, which requires consistent funding, as well as legal, technical and informational support. Managerial implications comprise implications for business owners and for banks. We show that business owners may tangibly benefit from entering into partnerships with other businesspeople, by strengthening their resilience in times of major disruptions. We also show that in the case of strategic market risk, the possibility to limit the risk brings significant value to businesses. The implication for banks is that for bank managers, a viable option could be to account for a type of business legal form in the process of evaluation of a firm's credibility (as we observed that the business legal form determines the level of vulnerability to exogenous shocks).
Our study has several limitations. First of all, as this is based on survey results, it could result in a subjective bias. Further research on the vulnerability to COVID-19 shock of the businesses run by the households may shed some light on the results provided in this study. The second limitation stems from the timeline of the study. The survey was conducted January-February, 2021 while in the following year the situation evolved. The economy, which had already been weakened by the earlier waves of COVID-19, had to deal with the next stages of the turmoil in the markets. At the same time, a number of solutions supporting business processes in pandemic conditions were implemented. This could be influential on their perception of risk. Thus, by repeating the survey, the problem could be understood more comprehensively. Another limitation is the set of COVID-19 disruptions considered in this study. It has limited the abilities to study households' riskperception comprehensively, as only some specific risks have been considered (the business perspective). Thus, further inquiries should be placed to study the effect of business legal form on the perception of other types of risks (e.g., natural catastrophes) by households running a business.

Conclusions
Fear of the future is amongst the most important reasons why entrepreneurs do not engage in business (Cacciotti et al. 2016). This study was designed to report how the choice of business legal form affects perceptions of COVID-19-related interruptions among households running a business. This work adds primarily to the literature on household risk coping mechanisms, by revising the perceptions of COVID-19 disruptions among households running their own business in forms which vary with respect to available risk coping mechanisms. Based on the survey results on small-and medium-sized businesses operating in Poland, we provide strong evidence that COVID-19 was perceived as more disruptive by sole proprietorships than by partnerships, including general partnerships and limited liability companies. There were no significant differences between general partnerships and limited liability companies in their perception of the majority of interruptions related to COVID-19 except from interruptions related to continuity of sales. Partnerships allow for intra-household risk sharing, while only limited liability companies allow for risk limiting. Thus, our results support that intra-household risk-sharing mechanisms (as a way to cope with a shock) appear to be more important in safeguarding households running businesses in times of pandemic, than formal mechanisms of reducing the liability Risks 2022, 10, 82 13 of 17 of individuals running a business. We conclude that strengthening social and business ties between entrepreneurs can efficiently mitigate the perception of the number of risks related to exogenous shock. We also showed that in the case of strategic market risk, the possibility to limit the risk brings significant value to the household businesses. Effective risk management by household businesses is critical for their ability to survive, as well as to generate income for households. This mechanism contributes to the development of a business itself, and at the same time to its social and market environment. In this respect, our study has a number of important practical and theoretical implications. Data Availability Statement: Data available on request due to privacy restrictions.
