Double Generalized Spatial Econometric Models

The authors offer a unified method extending traditional spatial dependence with normally distributed error terms to a new class of spatial models based on the biparametric exponential family of distributions. Joint modeling of the mean and variance (or precision) parameters is proposed in this family of distributions, including spatial correlation. The proposed models are applied for analyzing Colombian land concentration, assuming that the variable of interest follows normal, gamma, and beta distributions. In all cases, the models were fitted using Bayesian methodology with the Markov Chain Monte Carlo (MCMC) algorithm for sampling from joint posterior distribution of the model parameters.     

The Gender Wage Gap and Poverty in Colombia

Abstract. Using 19 years of cross‐section wage data, we look at the trend of the ratio of male to female wages in Colombia. First, we observe a long‐term trend towards an increase in the gender wage gap that may be related to new labor regulations giving more protection to women and thereby raising the cost of female employment for firms. Second, we measure the impact on poverty of the increasing gap by producing estimates of the income distribution for the subsequent years had the wage gap remained at the low level it used to be in the early 1990s. As mainly low‐skilled women suffered from the increase in the wage gap, we find that the phenomenon contributed to an overall increase in poverty during the decade.     

Assessing international organizations’ support to social enterprise

This article takes stock of a sample of interventions and programmes across different countries and regions supported by international organizations to foster the development of social enterprise. The primary objective of the article is to generate a compilation of such interventions and draw some lessons about their potential contribution to the growth and sustainability of the sector. The results indicate that international organizations’ support to social enterprise has focused primarily on the provision of financial resources, notably loans and grants. While programmes remain largely unassessed, the few available rigorous evaluations show that social enterprise has the potential to be a cost‐effective mechanism to deliver basic social services to the poor. The article proposes a set of policy recommendations directed primarily to international organizations and the public administration to improve and enhance their support to the sector.

The Impact on Inequality of Raising the Minimum Wage: Gap‐narrowing and Reranking Effects

Raising the minimum wage may reduce inequality by increasing the wages of low‐skill workers, but it may also increase inequality due to negative impacts on employment that produce wage losses. Using previous estimates of the elasticities of wages and employment to changes in the minimum wage in Colombia and Brazil, we show that the net impact on inequality of increasing the minimum wage may depend on the distributional weights used for inequality measurement. The results are obtained by decomposing the Gini index into reranking and gap‐narrowing effects. Inequality‐increasing reranking effects, which are associated with job losses, may dominate inequality‐decreasing gap‐narrowing effects, which are associated with wage gains, when high weights are placed on workers with low earnings. For standard distributional weights, however, the likely net impact is a reduction in wage inequality.
