Essays on Informal Labor Markets


Book Description

The dissertation deals with the analysis of informality in developing countries considering both the worker's and the firm's perspective. Within a context of a strong presence of this phenomenon in the majority of South and Central America countries, the main goal of this research is to explore the factors that may influence the prevalence and the consequences of informality in this region. The analysis focuses in two dimensions of the informal labor market: the firms and the workforce, divided in three main topics. The initial point of analysis intends to provide evidence of the presence of informal firms and its differences between the South and Central America countries. Therefore, we evaluate which are the cross-national factors that account for the prevalence of informality and we try to identify the reason influencing the decision to run a business in the borderlines of the formal or informal sector in this region. It is worth mentioning that with these objectives in mind, this study is the first analysis using firm-level data covering a wide sample of South and Central America countries. In this sense, we found three main results on firms' informality. Firstly, it sheds light on the association between informality and the characteristics of firms. In this sense, small firms, less productive firms, older firms, one proprietor firms, less technological firms and manufacturing firms are more likely to operate informally. As second result, it reveals that entrepreneurs face obstacles in their operations, such as the presence of informal competitors, financial and tax administration obstacles, which positively influence informality. Thirdly, it analyses the effect of cross-country determinants of the likelihood of being informal firm. These factors are associated with the average GDP growth and the governance performance of the country. While the previous analysis addresses informality as a challenge issue to deal with in developing countries, the next two analyses focus their attention in Ecuador. The next tòpic explains the determinants of the job placement process in the Ecuadorian formal and informal labor market. In this regard, it seeks to answer weather being part of an informal job is a worker's voluntary decision, or it is because there are restrictions on the number of job placements in the formal sector. In order to consider both workers' preferences and employers' hiring decisions, we apply a bivariate binomial probit model with partial observability since we can only observe the joint decision of both actors of the market. The study supports the presence of a restriction in the number of formal jobs in the economy and therefore existence of both, voluntary and involuntary informal employment. Nonetheless, these results lead directly to a next question, explicitly, how are the dynamics of the formal and informal sectors and which paterns affected the transitions within the labor sectors. Therefore, the next topic provides an overview of the dynamics of the formal and informal sectors and some specific patterns of the transitions within the labor sectors. We specify a transition matrix and a multinomial logit model to identify the movements across the sectors and the effect of each worker's characteristics on the probability of moving to a given a sector. The transition matrix results suggest an important dynamics not only in and out of the labor market but also across the sectors; and as well that individuals are searching for job opportunities in both formal and informal sectors.






















Essays on Labor Markets in Developing Countries


Book Description

My dissertation consists of three chapters. The first chapter examines social networks in labor markets. While existing theories such as models of screening and peer effects imply that social networks improve job match quality, these theories do not well explain the stylized fact, which we call negative selection---workers and employers with lower socio-economic status use social networks more frequently. By proposing an equilibrium search model, we show that social networks create mismatched jobs in the context where negative selection occurs. Our model sheds light on a neglected aspect of social networks: they help to match, but not necessarily with good-match partners. In the presence of search frictions, workers and firms can be tempted by bad-match encounters through social networks. This temptation is stronger for less productive, poorer workers and firms because costly formal channels are less rewarding for them. Using linked employer-employee data in Bangladesh, we find that matching through social networks rather than formal channels results in mismatches. This chapter demonstrates that while social networks compensate for search frictions in formal labor markets by matching more workers and jobs, their match quality is low. The second chapter evaluates the effects of social security benefits on labor supply. The benefits can reduce labor supply through two channels: current benefits and expectations over future benefits. I develop a framework to jointly estimate both channels and apply it to the South African pension program, which lowered the male eligible age in 2008 to 2010. I find the anticipatory effect of future benefits to be considerable: it accounts for nearly 60 percent of the labor force contraction caused by the lowering of the eligible age. Moreover, the framework identifies binding liquidity constraints faced by nearly-age-eligible people. The third chapter examines spillover effects of the South African Old-Age Pension Program on employment choices of recipients' children. By exploiting quasi-experimental variations in eligibility, the empirical results show that prime-age children leave the labor force if their fathers receive pension benefits. I find suggestive evidence that they leave the labor force to receive education and training. I also find suggestive evidence that the benefits allow prime-age individuals to look for jobs for longer duration. These findings imply that the program does not discourage work but help prime-age individuals move to more productive jobs.




Three Empirical Essays on Education and Informality in the Labor Market of a Developing Country


Book Description

1) Informality and Overeducation in the Labor Market of a Developing Country This chapter explores the connection between labor market segmentation in two sectors, a modern protected formal sector and a traditional- unprotected-informal sector, and overeducation in a developing country. Informality is thought to have negative consequences, primarily through poorer working conditions, lack of social security, as well as low levels of productivity throughout the economy. This chapter considers an aspect that has not been previously addressed, namely the fact that informality might also affect the way workers match their actual education with that required performing their job. Using micro-data from Colombia the relationship between overeducation and informality is tested. Empirical results suggest that, once the endogeneity of employment choice has been accounted for, formal male workers are less likely to be overeducated. Interestingly, the propensity of being overeducated among women does not seem to be closely related to the sector choice. 2) Double Penalty in Returns to Education: Informality and Educational Mismatch in the Colombian Labor Market This chapter examines the returns to education taking into consideration the existence of educational mismatches in the formal and informal employment of a developing country. Results show that the returns of surplus, required and deficit years of schooling are different in the two sectors. Moreover, they suggest that these returns vary along the wage distribution, and that the pattern of variation differs for formal and informal workers. In particular, informal workers face not only lower returns to their education, but suffer a second penalty associated with educational mismatches that puts them at a greater disadvantage compare to their formal counterparts. 3) Wage Gaps Across Colombian Regions: The Role of Education and Informality This chapter analyzes the role of education and informality on regional wage differentials. The hypothesis that is put under examination is that apart from the difference in the endowments of human capital across regions, regional heterogeneity in the incidence of informality may be another important source of regional wage inequality. The results for Colombian regions confirm marked differences in wage distributions between regions and that they differ in the endowment of human capital and more importantly in the incidence of informality. Regional heterogeneity in returns to education is especially intense in the upper part of the wage distribution. While heterogeneity in the informal pay penalty throughout the territory is more relevant in the lower part of the wage distribution.
