Does higher income cause democracy? Accounting for the dynamic nature and high persistence of income and democracy, we find a statistically significant positive relation between income and democracy for a postwar period sample of up to 150 countries. Our results are robust across different...

This paper considers a generalized panel data model of polychotomous and/or sequential switching which can also accommodate the dependence between unobserved effects and covariates in the model. We showcase our model using an empirical illustration in which we estimate scope economies for the...

Pesaran and Yamagata (Pesaran, M.H., Yamagata, T., Testing slope homogeneity in large panels, Journal of Econometrics 142, 50–93, 2008) propose a test for slope homogeneity in large panels, which has become very popular in the literature. However, the test cannot deal with the practically...

In this paper, we test the Prebish–Singer (PS) hypothesis, which states that real commodity prices decline in the long run, using two recent powerful panel data stationarity tests accounting for cross-sectional dependence and a structural break. We find that the hypothesis cannot be rejected...

We examine whether subjective information routinely collected in general surveys can be used to construct a single measure of underlying match quality which helps test matching models and predict labour market outcomes of workers.

Ng (2008) shows how the cross-sectional variance of the observed panel data can be used to construct a simple test for the proportion of non-stationary units. However, in the case with incidental trends the test is distorted. The present note shows how the distortions can be substantially...

The purpose of this paper is to test the hypothesis first documented by Romer (1993), that inflation is lower in more open economies. According to this hypothesis, central banks have a smaller incentive to engineer surprise inflations in economies that are more open because the Phillips curve is...

This paper develops a simple test à la Pesaran (2007) for the null hypothesis of stationarity in heterogeneous panel data with cross-sectional dependence in the form of a common factor in the disturbance. We also allow for serial correlation.

We examine the effects of hurricane shocks on key migration variables in US coastal counties. Results show that hurricane strikes increase the outward migration rate and that these migrants were somewhat wealthier, but that there was no impact on inward migration.

In an influential paper, Acemoglu et al. (2008) find that the positive correlation between income per capita and the level of democracy across countries vanishes once country-specific effects are accounted for. In this paper, we find evidence of a non-linear effect from income to democracy even...
