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...

Foreign Direct Investment has become an important source of long-term capital inflows for less developed countries in the last two decades. As documented in previous literature, FDI flows may increase permanently domestic output and represent an important source of technological spillovers for...

Three basic mechanisms are behind the statistical relationship between fertility decisions and labor force participation decisions. 1) Causal direct effect: the time spent in child-care reduces the labor market effort leading to a temporary drop in post-birth labor force participation. 2) Causal...

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 t is...

In this paper we investigate whether local governments react on the welfare benefit levels in neighboring jurisdictions when setting their own benefit levels. We solve the simultaneity problem arising from the welfare game by utilizing a policy intervention; more specifically, we use a centrally...

This paper provides a framework that aims at distinguishing the technological economies of vertical integration from the vertical economies resulting from market imperfections. To illustrate our analyze, we use consistent panel data econometric methods to estimate cost functions on a sample of...

The September 11, 2001 terrorist attack to the twin towers and ensuing heightened national security measures worldwide, but particularly in the United States, are modeled to be equivalent to a thickening of trade barriers in international trade. By estimating a gravity model with a stochastic...

This paper proposes a regression model for analysis of panel count data with the presence of excess zeros relative to a negative binomial distribution, in which the frequency distribution of counts changes according to an underlying two-state Markov chain. Features of the proposed model and...

The pervasive role of information and communications technology (ICT) in the new economy is well documented. There is now considerable agreement among scholars regarding the ICT contribution to national productivity growth. On the other hand, the production spillover and network externality...

In this paper, we investigate the role of the components of demographic change on economic development. Population growth has both positive and negative effects on income growth. Kelley and Schmidt (1995) states that high birth rates are costly in terms of growth but this effect can be offset by...
