We develop a novel framework to analyze the structural implications of the marriage market for house-hold consumption patterns. We start by de…ning a revealed preference characterization of e¢ cient householdconsumption when the marriage is stable. In particular, stability means that the...

This paper introduces rank-based tests for the cointegrating rank in an Error CorrectionModel with i.i.d. elliptical innovations. The tests are asymptotically distribution-free,and their validity does not depend on the actual distribution of the innovations. Thisresult holds despite the fact...

We consider testing about the slope parameter ß when Y - X ß is assumed to be an exchangeable process conditionally on X. This framework encompasses the semi-parametric linear regression model. We show that the usual Fisher’s procedure have non trivial exact rejection bound under the null...

La pregunta básica de investigación detrás de este trabajo es cómo difiere la valoración económica de un bien ambiental considerando beneficiarios circundantes(quienes viven cerca del bien en cuestión) y no circundantes (quienes habitando el país donde se encuentra el bien, viven en...

Las decisiones de otorgamiento de crédito son cruciales en la administración de riesgos. Las instituciones financieras han desarrollado y usado modelos de credit scoring para estandarizar y automatizar las decisiones de crédito, sin embargo, no es común encontrar metodologías para...

The present paper proposes a strategy for estimating panel data models in the presence of sample selection and endogeneity arising from endogenous explanatory variables and unobserved heterogeneity. We propose three alternative tests for selection bias and estimation strategies to correct for...

Using parametric and non-parametric estimation techniques, we analyze the sustainability of the recently growing current account imbalances in the Euro Area and test whether the introduction of the European Monetary Union has aggravated these imbalances. For these purposes two alternative...

This paper analyzes estimators based on the instrumental variable quantile regression (IVQR) model (Chernozhukov and Hansen, 2004, 2005, 2006) under the local quantile treatment effects (LQTE) framework (Abadie et al., 2002). I show that the quantile treatment effect (QTE) estimators in the IVQR...

The leverage effect refers to the generally negative correlation between an asset return and its changes of volatility. A natural estimate consists in using the empirical correlation between the daily returns and the changes of daily volatility estimated from high frequency data. The puzzle lies...

Recently regime-switching models have become the standard tool for modeling electricity prices. These models capture the main properties of electricity spot prices well but estimation of the model parameters requires computer intensive methods. Moreover, the distribution of the price spikes must...
