Changes in the Panamanian wage structure: a quantile regression analysis

Los cambios en la estructura salarial de un país es un área importante de investigación. Sin embargo, la evidencia empírica sobre la evolución de salarios en los países en desarrollo aún es escasa. En este artículo, intentamos contribuir a esta brecha al estudiar la evolución de la estructura salarial en Panamá para el período 1982-1997. Modelamos la distribución (condicional) de los salarios usando la técnica de regresión por cuantiles y aplicamos este modelo para estudiar la distribución del salario de los hombres y su evolución en Panamá durante las últimas dos décadas. Encontramos que la estructura salarial permaneció relativamente estable en el período considerado.The changes in the wage structure of a country are an important area of research. However, the empirical evidence about the evolution of wages in developing countries is still quite scant. In this paper we contribute to fill this gap by studying the evolution of the wage structure in Panama for the period 1982-1997. We model the (conditional) distribution of wages by means of the quantile regression technique and apply this model to study the male wage distribution and its evolution during the last two decades in Panama. Overall, we find that the wage structure remained fairly stable over the period studied.Instituto de Investigaciones Económica

Randomization Inference in the Regression Discontinuity Design: An Application to Party Advantages in the U.S. Senate ∗

In the Regression Discontinuity (RD) design, units are assigned a treatment based on whether their value of an observed covariate is above or below a fixed cutoff. Under the assumption that the distribution of potential confounders changes continuously around the cutoff, the discontinuous jump in the probability of treatment assignment can be used to identify the treatment effect. Although a recent strand of the RD literature advocates interpreting this design as a local randomized experiment, the standard approach to estimation and inference is based solely on continuity assumptions that do not justify this interpretation. In this article, we provide precise conditions in a randomization-inference context under which this interpretation is directly justified, and develop exact finite-sample inference procedures based on them. Our randomization-inference framework is motivated by the observation that only a few observations might be available close enough to the threshold where local randomization is plausible, and hence standard large-sample procedures may be suspect. Our proposed methodology is intended as a complement and a robustness check to standar
