Assortative Matching and the Education Gap

This paper attempts to explain the decrease and reversal of the education gap between males and females. Given a continuum of agents, the education decisions are modelled as an assignment game with endogenous types. In the first stage agents choose their education level and in the second they participate in the labor and marriage markets. Competition among potential matches ensures that the efficient education levels can always be sustained in equilibrium, but there may be inefficient equilibria. Combining asymmetries intrinsic to the modelled markets the model reproduces the observed education gap.Assortative matching, efficiency, gender, education. Classification JEL:

A Proposal to Improve Our Understanding of Entrepreneurship Using the Panel Study of Income Dynamics

This paper aims to evidence how relatively marginal changes in the Panel Study of Income Dynamics survey, particularly on the measurement of returns to entrepreneurship - both financial and human capital - can yield sizeable benefits for research and policy on entrepreneurship. Accurate measurement of returns to all the resources invested in entrepreneurial endeavors is not only essential to understand the motivations and barriers to start a business, but can ultimately provide the basis to improve the effectiveness of programs and policies to foster entrepreneurial activity in the economy.In fact, recent studies question the importance of pecuniary benefits in the decision to become an entrepreneur. However, these are based on measures of total earnings and sample aggregate returns. Thus, adequate individual data on business income and its components has an enormous value for both research and policy design altogether.entrepreneurship, returns to entrepreneurship, survey, PSID

The Persistent Gender Earnings Gap in Colombia, 1994-2006

This paper surveys gender earnings gaps in Colombia from 1994 to 2006, using matching comparisons to examine the extent to which individuals with similar human capital characteristics earn different wages. Three sub-periods are considered: 1994-1998; 2000-2001; and 2002- 2006, corresponding to the economic cycle of the Colombian economy. The gaps dropped from the first to the second period but remained almost unchanged between the second and the third. The gender earnings gap remains largely unexplained after controlling for different combinations of socio-demographics and job-related characteristics, reaching between 13 and 23 percent of average female earnings. That gap is lower at the middle of the wage distributions than the extremes, possibly due to a gender-equalizing effect of the minimum wage. Moreover, the gap is more pronounced for low-productivity workers and those who need flexibility to participate in labor markets. This suggests that policy interventions in the form of labor market regulations may have little impact on reducing gender earnings gaps.gender, ethnicity, wage gaps, Latin America, Colombia, matching

Business Ownership and Self-Employment in Developing Economies: The Colombian Case

We characterize entrepreneurship in developing economies through a case study for Colombia. We document self-employment and business ownership since the 1980s; while the relative size of these groups within the labor force is stable across time, they differ significantly in important observable dimensions such as education and business sector. We then study the motivations to become an entrepreneur. First, we analyze the transition into and out of potential forms of entrepreneurship by measuring the flows across occupations, and study the determinants of entry and exit into and out of self-employment and business ownership; there is surprisingly little transition between self-employment and business ownership. Second, we focus on the financial motivations by measuring the differences in earnings of self-employment and businessownership relative to salaried work, at the mean and along the distribution. There is a substantial earnings premium to become a business owner, but it is not financially attractive to become self-employed. The results of this paper suggest that while business ownership is what the literature associates with entrepreneurship, self-employment is basically a subsistence activity.Entrepreneurship, self-employment, business ownership, transition prob-ability, earnings premium

Adjusting the Labor Supply to Mitigate Violent Shocks: Evidence from Rural Colombia

This paper studies the use of labor markets to mitigate the impact of violent shocks on households in rural areas in Colombia. It examines changes in the labor supply from on-farm to off-farm labor as a means of coping with the violent shock and the ensuing redistribution of time within households. It identifies the heterogeneous response by gender. Because the incidence of violent shocks is not exogenous, the analysis uses instrumental variables that capture several dimensions of the cost of exercising terror. As a response to the violent shocks, households decrease the time spent on on-farm work and increase their supply of labor to off-farm activities (non-agricultural ones). Men carry the bulk of the adjustment in the use of time inasmuch as they supply the most hours to off-farm non-agricultural work and formal labor markets. Labor markets do not fully absorb the additional labor supply. Women in particular are unable to find jobs in formal labor markets and men have increased time dedicated to leisure and household chores. Additional off-farm supply does not fully cover the decrease in consumption. The results suggest that in rural Colombia, labor markets are a limited alternative for coping with violent shocks. Thus, policies in conflict-affected countries should go beyond short-term relief and aim at preventing labor markets from collapsing and at supporting the recovery of agricultural production.Conflict, labor markets, developing economies, instrumental variables

El efecto de la maternidad sobre los salarios femeninos

El presente trabajo analiza el efecto del número y de la estructura de edades de los hijos sobre los salarios de las mujeres en Colombia. Las madres ganan en promedio 17.6% menos que las no madres. Como no todas las mujeres participan en el mercado laboral,existen potenciales problemas de selección que son corregidos. Los resultados empíricos confirman la existencia de una penalización salarial sustancial por maternidad. Se estima que luego de controlar por variables observables y sesgo de selección, aún persiste una brecha salarial de 9.4% entre madres y no madres; la brecha salarial es más alta cuando los hijos tienen menos de 5 años de edad, 18.4%. Este diferencial salarial se debe en parte a que las madres son empleadas con mayor probabilidad en trabajos de peor calidad que las no madres, donde no se contribuye a salud ni a pensión, y a que ser madre está relacionado con mayores responsabilidades domésticas al interior del hogar.maternidad, brecha salarial, sesgo de selección, Colombia

Unemployment Insurance in the Presence of an Informal Sector

We study the effect of UI bene?ts in a typical developing country where the informal sector is sizeable and persistent. In a partial equilibrium environment, ruling out the macroeconomic consequences of UI benefits, we characterize the stationary equilibrium of an economy where policyholders may be employed in the formal sector, short-run unemployed receiving UI benefits or long-run unemployed without UI benefits. We perform comparative static exercises to understand how UI benefits affect unemployed workers'effort to secure a formal job and their labor supply in the informal sector. Our model reveals that an increase in UI benefits generates two opposing effects for the short-run unemployed. First, since search efforts cannot be monitored it generates moral hazard behaviours that lower effort. Second, it generates an income effect as it reduces the marginal cost of searching for a formal job and increases effort. Even though in general it is ambiguous which effect dominates, we show that for short durations UI benefits increase unemployed worker's effort to secure a formal-sector job and decreases informal-sector work
