Entrepreneurship in the Shadows: Wealth Constraints and Government Policy

I develop a dynamic model of forward-looking entrepreneurs, who decide whether to operate in the formal economy or informal economy and choose how much to invest in their businesses, taking government policy as given. The government has access to two policy tools: taxes on formal business activity and enforcement (or policing) discouraging informality. The main focus of the paper is on transitional dynamics under different initial wealth levels. Whether an initially small business will be trapped in the informal economy and remain small forever or grow quickly and become a large formal business depends on tax and enforcement policies. High tax rates accompanied by loose enforcement – which is mostly the case in less-developed countries (LDCs) – induce tax avoidance, discourage investment in formal businesses, and drive the entrepreneurial activity toward the informal sector even though the initial wealth level is high. Lowering taxes on formal activity joined with strict enforcement can help reducing the magnitude of poverty traps in LDCs

The use of natural experiments in migration research

Estimating the causal effect of immigration on the labor market outcomes of native workers has been a major concern in the literature. Because immigrants decide whether and where to migrate, immigrant populations generally consist of individuals with characteristics that differ from those of a randomly selected sample. One solution is to focus on events such as civil wars and natural catastrophes that generate rapid and unexpected flows of refugees into a country unrelated to their personal characteristics, location, and employment preferences. These “natural experiments” yield estimates that find small negative effects on native workers’ employment but not on wages

Informal versus Formal Search: Which Yields a Better Pay?

Estimates on the effect of job contact method – i.e., informal versus formal search – on wage offers vary considerably across studies, with some of them finding a positive correlation between getting help from informal connections and obtaining high-paying jobs, while others finding a negative one. In this paper, I theoretically investigate the sources of discrepancies in these empirical results. Using a formal job search framework, I derive an equilibrium wage distribution which reveals that the informal search yields for some groups higher and for some others lower wages than formal search. The key result is the existence of nonmonotonicities in wage offers. Two potential sources of these nonmonotonicities exist: (i) peer effects and (ii) unobserved worker heterogeneity in terms of the inherent cost of maintaining connections within a productive informal network. The model predicts that a greater degree of unobserved heterogeneity tilts the estimates toward producing a positive correlation between informal search and higher wages, whereas stronger peer influences tend to yield a negative correlation. This conclusion informs the empirical research in the sense that identification of the true correlation between job contact methods and wage offers requires a careful assessment of the unobserved heterogeneity and peer influences in the relevant sample

Social Interactions in Job Satisfaction

The literature documents that job satisfaction is positively correlated with worker performance and productivity. We examine whether aggregate job satisfaction in a certain labor market environment can have an impact on individual-level job satisfaction. If the answer is yes, then policies targeted to increase job satisfaction can increase productivity not only directly, but through spillover externalities too. We seek an answer to this question using two different data sets from the United Kingdom characterizing two different labor market environments: Workplace Employment Relations Survey (WERS) at the workplace level (i.e., narrowly defined worker groups) and British Household Panel Survey (BHPS) at the local labor market level (i.e., larger worker groups defined in industry x region cells). Implementing an original empirical strategy to identify spillover effects, we find that one standard deviation increase in aggregate job satisfaction leads to a 0.42 standard deviation increase in individual-level job satisfaction at the workplace level and 0.15 standard deviation increase in individual-level job satisfaction at the local labor market level. These social interactions effects are sizable and should not be ignored in assessing the effectiveness of the policies designed to improve job satisfaction

Do Vocational High School Graduates Have Better Employment Outcomes than General High School Graduates?

This paper estimates the causal effect of vocational high school (VHS) education on employment likeli-hood relative to general high school (GHS) education in Turkey using census data. To address non-random selection into high school types, we collect construction dates of the VHSs at the town-level and use VHS availability in the town by age 13 as an instrumental variable. The first-stage estimates suggest that the availability of VHS does not affect the overall high school graduation rates, but gener-ates a substitution from GHS to VHS. The OLS estimates yield the result that the individuals with a VHS degree are around 5 percentage points more likely to be employed compared to those with a GHS de-gree. When we use the availability of VHS as an instrumental variable, we still find positive and statisti-cally significant effect of VHS degree on employment likelihood relative to GHS degree. However, once we include town-specific socio-economic variables to control for education, employment, and business activity levels in the town, the IV estimates get much smaller and become statistically insignificant. We conclude that although the VHS construction generates a substitution from GHS to VHS education, this substitution is not transformed into increased employment rates in a statistically significant way. We also argue that location-specific controls improve the reliability of the school construction/proximity instruments

The impact of the 2008 crisis on top labor incomes in Turkey: A nonparametric analysis

This paper presents a nonparametric analysis of the impact of the 2008 crisis on earnings distribution in Turkey. Using micro-level data from the Household Labor Force Survey (2004-2011), I show that the crisis has operated most visibly above the upper quartile of the earnings distribution. I present three main findings: (1) the share of the top decile -- especially the top percentile -- has increased significantly right after the crisis, (2) the top quartile (i.e., the right tail) of labor incomes in Turkey resembles, on average, a Pareto distribution with a corresponding Gini coefficient of around 0.23, and (3) following the crisis, the earnings differentials have widened above the top quartile and wildly deviated from the Pareto form. I document that the changes observed right after the crisis have mostly been temporary; that is, a normalization process has operated in the aftermath of the crisis. I argue that the health of the domestic banking system might be an important determinant of the effect of large scale financial crises on top labor incomes. A sound banking system can generate income polarization in a country, when global crises lead to asymmetric income reallocations across sectors

Day-of-the-Week Effects in Subjective Well-Being: Does Selectivity Matter?

Individuals tend to self-report higher well-being levels on certain days of the weeks than they do on the remaining days, controlling for observables. Using the 2008 release of the British Household Panel Survey, we test whether this empirical observation suffers from selection bias. In other words, we examine if subjective well-being is correlated with unobserved characteristics that lead the individuals to take the interview on specific days of the week. We focus on two distinct well-being measures: job satisfaction and happiness. We provide convincing evidence for both of these measures that the interviews are not randomly distributed across the days of the week. In other words, individuals with certain unobserved characteristics tend to take the interviews selectively. We conclude that a considerable part of the day-of-the-week patterns can be explained by a standard "non-random sorting on unobservables" argument rather than "mood fluctuations." This means that the day-of-the-week estimates reported in the literature are likely to be biased and should be treated cautiously
