It has been found that the t-statistic for testing the null of no relationship between two independent variables diverges asymptotically under a wide variety of nonstationary data generating processes. This paper introduces a simple method which guarantees convergence of this t-statistic to a...

Model specification and selection are recurring themes in econometric analysis. Both topics become considerably more complicated in the case of large-dimensional data sets where the set of specification possibilities can become quite large. In the context of linear regression models, penalised...

This paper deals with instability in regression coefficients. We propose a Bayesian regression model with time-varying coefficients (TVC) that allows to jointly estimate the degree of instability and the time-path of the coefficients. Thanks to the computational tractability of the model and to...

We examine the performance of asymptotic inference as well as bootstrap tests for the Alphabeta and Kobus-Mi±o´s family of inequality indices for ordered response data. We use Monte Carlo experiments to compare the empirical size and statistical power of asymptotic inference and the...

Este estudio presenta evidencia empírica sobre los determinantes de la adopción de certificaciones internacionales de calidad (ISO) y sus efectos sobre el desempeño de las empresas argentinas en los años 2006 y 2010. Los resultados indican que las firmas exportadoras, extranjeras y de mayor...

This paper studies the influence of interregional inequality within countries on internal con-flicts. Regional inequalities are measured by the population-weighted coefficient of variation of regional GDP per capita. As the main innovation, I use a panel data set of country-level re- gional...

The determinants of risk attitude in couples are explored using data from the German Socio-Economic Panel over the period 2004 to 2009. The focus of the analysis is the repeated responses to the survey question about general willingness to take risk. Responses to this question are provided on a...

This paper investigates Turkey?s sectoral trade flows to the EU based on panel data from the period 1988 to 2002. Turkey?s sixteen most important export sectors are analysed. Emphasis is placed on the role of price competition, EU protection, and transport costs in the export trade between...

In this study, MERCOSUR\'s past exports to the EU under the protectionist environment of the period between 1988 and 1996 are examined and an attempt is made to determine MERCOSUR\'s exports\' growth potential in a liberalised EU market. A sectoral study is considered indispensable since tariff...
