The estimated parameters of output distance functions frequently violate the monotonicity, quasi-convexity and convexity constraints implied by economic theory, leading to estimated elasticities and shadow prices that are incorrectly signed, and ultimately to perverse conclusions concerning the...

Este trabajo presenta un modelo de frontera estocástica con parámetros aleatorios en el componente de ineficiencia aplicado al sector bancario. Este modelo permite capturar la influencia de las exposiciones de riesgo sobre la eficiencia bancaria y distingue estos efectos entre bancos con...

One of the most enduring problems in cross-section or panel data models is heterogeneity among individual observations. Different approaches have been proposed to deal with this issue, but threshold regression models offer intuitively appealing econometric methods to account for heterogeneity....

The findings of recent studies on adjustment processes suggest that regional labour markets in the EU and the US differ significantly. Low wage flexibility and limited labour mobility in European countries involve persistent unemployment differentials across regions. However, the spatial...

The inclusion of spatial correlation of house price in hedonic pricing model may produce better marginal implicit price estimate(s) of the environmental variable(s) of interest. Most applications where a spatial econometric model is applied to the estimation of a hedonic property value model...

This paper investigates non-linearity in spatial processes models and allows for a gradual regime-switching structure in the form of a smooth transition autoregressive process. Until now, applications of the smooth transition autoregressive (STAR) model have been largely confined to the time...

My dissertation consists of four papers embedded within the Economic Geography field. The first paper analyzes economic growth and convergence from a time series perspective focusing on regional labor markets. The second paper uses microdata to evaluate what is termed conditional sigma...

This dissertation examines the effects of commodity market liberalization on the farmer's price. Chapter two of this dissertation presents a theoretical model of commodity market liberalization which aims to analyze the impact of market liberalization on the farmer's price. This monopsony-type...

Spatial econometrics is a subfield of econometrics that deals with the treatment of spatialinteractions in regression models for cross sectional and panel data.Chapter 1: This is the first paper that highlights the role of spatial interactions, in thecontext of bankruptcy laws, in the...

Theories of economic growth have long recognized that the majority of growth resultsfrom endogenous changes in technology that emerge from the profit motivateddevelopment of new knowledge. However, recent theorizing has suggested that thecreation of knowledge in and of itself does not directly...
