Resumen
We study the effect of UI benefits in a typical developing country where the informal sector is sizeable and persistent. In a partial equilibrium environment we characterize the stationary equilibrium of an economy where policyholders may be employed in the formal sector, short-run unemployed receiving UI benefits and 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, their labor supply in the informal sector and leisure time. 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. The overall effect is ambiguous and depends on the relative strength of these two effects. Additionally, we show that an increase in UI benefits increases the efforts of long-run unemployed workers. Using data from Brazil to calibrate the parameters of the model we provide a simple simulation exercise which suggests that the income effect pointed out is not necessarily of second-order importance in comparison with moral hazard strength: An increase in UI benefits may increase unemployed workers efforts to secure a job in the formal sector, instead of increasing informal-sector work. This result softens the widespread opinion that the presence of dual labor markets is an obstacle to providing UI in developing countries.
Resumen
Estudiamos los efectos del seguro de desempleo en un típico país en desarrollo, donde el sector informal es sustancial y persistente. Caracterizamos el equilibrio estacionario de un modelo de equilibrio parcial donde los agentes pueden estar empleados en el sector formal, desempleados de corto plazo recibiendo seguro de desempleo o desempleados de largo plazo sin seguro de desempleo. Realizamos ejercicios de estática comparativa para determinar el efecto de aumentar el seguro de desempleo sobre el esfuerzo de los agentes para conseguir un empleo formal, la oferta de trabajo en el sector informal y el tiempo de ocio. Nuestro modelo sugiere que un aumento en los beneficios del seguro de desempleo genera dos efectos encontrados sobre los desempleados de corto plazo. Primero, dado que los esfuerzos por buscar un empleo formal no se pueden monitorear se generan comportamientos de riesgo moral que disminuyen el esfuerzo. Segundo, hay un efecto ingreso que reduce el costo marginal de buscar un empleo formal que aumenta el esfuerzo. El efecto total es ambiguo y depende...
