This paper introduces the concept of homogeneous non-causality in heterogeneous panels. This concept is used to examine a panel of data for evidence of a causal relationship between GDP and carbon emissions. The technique is compared to the standard test for homogeneous non-causality in...

We consider the empirical relevance of two opposing hypotheses on the causality between income and democracy: The Democratic Transition claims that rising incomes cause a transition to democracy, whereas the Critical Junctures hypothesis denies this causal relation. Our empirical strategy is...

In recent years, a lot of rules concerning government expenditures as well as tax revenues were changed in Germany. Government expenditures in relation to GDP were reduced, income tax rates were lowered and the budget deficit declined. The structure of government expenditures changed in favor of...

This paper argues that there is a nonzero inflation-unemployment tradeoff in the long-run due to frictional growth, a phenomenon that encapsulates the interplay of nominal staggering and money growth. The existence of a downward-sloping long-run Phillips curve suggests the development of a...

Recent studies found evidence for nominal wage rigidity during periods of relatively high nominal GDP growth. It has been argued, however, that in an environment with low nominal GDP growth, when nominal wage cuts become customary, workers' opposition to nominal cuts would erode and, hence,...

This paper analyzes China's economic performance in the last 25 years and discusses its prospect for growth in the future. China has enjoyed high annual GDP growth rates of about ten percent in the last 25 years. Exports and investment were the two driving forces of the growth process. FDI plays...

The paper examines empirically the proposition that aid to poor countries is detrimental for external competitiveness, giving rise to Dutch disease type effects. At the aggregate level, aid is found to have a positive effect on growth of labour productivity. A sectoral decomposition shows that...

In this paper we adopt both a nonparametric and a semi-parametric IV estimator to show that the relationship between inflation and output growth is non-linear and that there exists a threshold level below which inflation has no effects on growth.

Comparing the emigration rates of countries at different stages of economic development, an inverse u-shape emerges. Although merely based on cross-sectional evidence, the "migration hump" is often treated as a causal relationship. Since the peak is located at rather high per capita incomes of...

Over the past 30 years (1990-2019), African economies have experienced remarkable improvements in real macroeconomic conditions, characterized by higher and more stable real per-capita growth rates, and lower and more stable inflation, which deserves to be called a ”Great African...
