This paper presents a new multivariate test for the detection of unit roots. Use is made of the possible correlations between the disturbances of different series, and constrained and unconstrained SURE estimators are employed. The corresponding asymptotic distributions are obtained and a table...

This paper investigates whether financial intermediary development influences macroeconomic technical efficiency on a sample of 47 countries, both developed and developing, over 1980-1995. We do so by applying Battese and Coelli (1995)’s method at the aggregate level. It is found that...

In 1996 free choice of health insurers has been introduced in the German social health insurance scheme. Competition between insurers was supposed to increase efficiency. A crucial precondition for effective competition among health insurers is that consumers search for lower-priced health...

A panel data set for six Central and Eastern European countries (the Czech Republic, Hungary, Poland, Romania, Slovakia and Slovenia) is used to estimate the monetary exchange rate model with panel cointegration methods, including the Pooled Mean Group estimator, the Fully Modified Least Square...

Using a novel data set from post-communist countries in the 1990s, this paper examines linkages between political constraints, economic reforms and growth. A dynamic panel analysis suggests public support for reform is negatively associated with income inequality and unemployment. Both the ex...

This paper analyzes the interaction of financial frictions and non- convex adjustment costs. With non-convex adjustment costs firms infrequently carry out discrete investment projects. Therefore, financial variables may influence investment in two ways. Theoretically, they can alter the...

This paper complements previous studies on the effects of health on wages by addressing the problems of unobserved heterogeneity, sample selection, and endogeneity in one comprehensive framework. Using data from the German Socio-Economic Panel (GSOEP) we find the health variable to suffer from...

While the causal relationship between migration and trade has not been studied thoroughly, estimation results of gravity model approach suggest that important aspects determining trade volumes can be missed if additional factors, including migration, are not considered. The current paper aims at...
