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...

This study employs state-level panel data to examine the effect of income inequality on crime in the United States. Using panel cointegration techniques, we find a significant negative effect of inequality on crime.

This paper investigates the quasi-maximum likelihood (QML) estimation of spatial panel data models where spatial weights matrices can be time varying. We show that QML estimate is consistent and asymptotically normal. We also derive the asymptotic distribution of average impact coefficients...

We obtain an LM test for the random effects probit model. In the natural parameterization of the model the necessary derivatives are identically zero under the null hypothesis. After a reparameterization, the feasible LM test is based on generalized residuals.

Unit specific effects are often used to estimate non-spatial efficiency. We extend such estimators to the case where there is spatial autoregressive dependence and introduce the concept of spillover efficiency. Intuitively, we present an approach to benchmark how successful units are at...

Based on a large international panel of surveyed GDP forecasts I analyze the frequency of forecast revisions and the factors that influence the likelihood of forecast revisions. I find that each month on average 40%–50% of forecasters revise their forecasts. In addition, I find that the...

This paper empirically tests for convergence in consumer price indices across 17 major cities in US over the 1918–2008 period. By using the novel OLS estimator introduced by Bao, Y., Dhongde, S., 2009. Testing convergence in income distribution. Oxford Bulletin of Economics and Statistics 71,...
