In this paper alternative approaches for testing the unit root hypothesis in panel data are considered. First, a robust version of the Dickey-Fuller t-statistic under contemporaneous correlated errors is suggested. Second, the GLS t-statistic is considered, which is based on the t-statistic of...

Studies on growth performance and catch-up and convergence of countries require and make extensive use of internationally and temporally comparable data on real gross domestic product (GDP) expressed in a common currency unit. The International Comparison Program (ICP), a project supported by...

We propose a novel estimator for the stochastic discount factor (SDF) in a panel-data context. Under general conditions it depends exclusively on appropriate averages of asset returns, and its computation is a direct exercise, as long as one has enough observations to our asymptotic results. We...

We investigate the relationship between exports and productivity in the Turkish apparel and motor vehicle and parts industries from 1990-1996, using two different models for plant-level panel data. In the first model, we examine the effect of past export status on current productivity both with...

In this paper we analyse contributions to a public good within an inter-generational framework where at the end of each session one generation of subjects leave advice for the succeeding generation via free form messages. Such advice can be private (advice left by one player in generation is...

Empirical studies of economic growth across countries are abundant and rich in conclusions, some of them widely accepted. This is not the case, however, with the empirics of business cycles. Particularly, there exists little evidence explaining why some countries take more time than others...

The non-negativity constraint on nominal interest rates may have been a major factor behind a putative structural break in the effectiveness of monetary policy. To check for the existence of such a break without making prior assumptions about timing, and to enable comparison between pre- and...

A method of principal components is employed to investigate nonlinear dynamic factor structure using a large panel data. The evidence suggests the possibility of nonlinearity in the U.S. while it excludes the class of nonlinearity that can generate endogenous fluctuation or chaos
