Individual's decisions regarding their retirement savings have usually been theoretically approached under the hypothesis that the Social Security System works as a substitute to other savings mechanisms. This document presents empirical evidence of the determinants and patterns of savings for...

Economic literature has focused on both causes and effects of trade union membership; however, most of the studies about trade unions in Colombia have been focused on its effects over wages and inequality. On this document we present an estimation of the structural determinants of trade union...

The 2002 Labor Reform was Ahmed to two specific purposes: implementation of social protection measures and labor law flexibilization. On this document we analyze some of the effects of the Reform, with specific emphasis on the potential changes on labor contract modalities, working hours and...

We use annual data on capital's share and relative factor prices from 35 US industries from 1960 to 2005 to test the induced innovation hypothesis. We derive, from a productionfunction framework, testable implications for the effect of contemporaneous and lagged factor price ratios on capital's...

In general, empirical studies on economics rely on the assumption of constant capital share of income both at the aggregate level and at the sector level. However, there is no empirical evidence supporting the constancy of capital share at the sector level. In this paper, using Colombian data,...

This paper uses Colombian household survey data collected over the period 1984-2005 to estimate Gini coeficients along with their corresponding standard errors. We find a statistically signicant increase in wage income inequality following the adoption of the liberalisation measures of the early...
