In this paper, we examine some important aspects related to safeguarding environmental quality. Beginning by defining the identity of the agents considered, we conceptually describe how whilethey have different identities, they can be simultaneously influenced by three distinct elements: self...

When the coefficients of a Tobit model are estimated by maximum likelihood their covariance matrix is typically, even if not necessarily, associated with the algorithm employed to maximize the likelihood. Covariance estimators used in practice are derived by: (1) the Hessian (observed...

This paper describes a methodology to calculate a spatial cost of living index using Colombian data for 2006 that takes into consideration the microeconomic behavior of households. Using the Almost Ideal Demand System and recovering the expenditure functions for the 23 main Colombian cities, the...

Survival prediction from a large number of covariates is a current focus of statistical and medical research. In this paper, we study a methodology known as the compound covariate prediction performed under univariate Cox proportional hazard models. We demonstrate via simulations and real data...

The aim of this article is to build a spatial housing price index for the Chilean communes (the commune political body similar to a municipality or county). The first step is to recover hedonic prices of three housing attributes by estimating a mixed index model (Bowden, 1992) using a...

Improved household accessibility to credit is identified as a significant determinant of intra-household re-allocation of labour resources with important implications for productivity, income, and poverty status. However, credit accessibility could also have wider impacts on poverty if it leads...

This paper uses a novel dataset collected by the first author from peri-urban areas of Ho Chi Minh City, Vietnam in 2008 to examine how the poor use their loans, and factors affecting their credit participation and credit constraints. The paper finds the presence of many commercial banks in the...

Interaction terms are often misinterpreted in the empirical economics literature by assuming that the coefficient of interest represents unconditional marginal changes. I present the correct way to estimate conditional marginal changes in a series of non-linear models including (ordered)...

We establish a `map' for describing a wide class of Limited Dependent Variables models much used in the econometric literature. The classification system, or language, is an extension of Amemiya's typology for tobit models and is intended to facilitate communication among researchers. The class...

This paper presents an estimation of the impacts of microcredit on labor and human capital following a quasi-experiment specifically designed to control for endogeneity and selection bias in the context of urban Mexico. We find important indirect trickle-down effects of credit through labor...
