Abstract

Resumen Publicamos anuncios de trabajo reales para observar la elección de personas buscando empleo en el mercado laboral Bogotano en su entorno natural. Disenamos un experimento de campo que se llevó a cabo en tres etapas. Primero, los aplicantes llenan su información básica para aplicar al puesto de trabajo y realizan una prueba previa al empleo para medir su productividad ex ante. Segundo, aleatorizamos a todos los aplicantes en diferentes tratamientos, variando el número de horas trabajadas a la semana y el grado de flexibilidad en el horario de trabajo. Finalmente, realizamos ofertas de trabajo reales a un subconjunto de aplicantes dentro de los que estaban interesados en continuar en el proceso de selección. Nuestro estudio es innovador porque tiene una medida ex ante de productividad que permite distinguir entre la productividad inducida por la selección (sorting) y la inducida por la motivación (u otras características ex post). Los resultados muestran que no se puede aumentar la productividad ex post al ofrecer contratos flexibles porque las personas más productivas no se seleccionan; es decir no hay evidencia de sorting. Sin embargo, encontramos que los contratos flexibles atraen más a mujeres con personas dependientes dentro del hogar. ***** Abstract We placed real job advertisements to observe labor market participants’ choices in their natural environment. We used a three stage experimental method. Following a standard job post, applicants had to fill in their credentials and to perform a pre-employment test to measure their ex ante productivity. We then randomized all participants into different treatments varying the flexibility in working hours and the total hours worked, and finally, made real job offers. Our study is innovative in that it has an ex ante measure of productivity that allows distinguishing between the enhanced productivity induced by sorting and the one induced by motivation (or other ex post features). We find that productivity cannot be raised by announcing flexible contracts because more productive individuals do not sort. We do find that flexible contracts attract more women with dependents.
