There is widespread concern about differences in the quality of state-run and private schooling. The concerns are especially severe in the numerous developing countries where much of the population has left state-provided schooling for private schooling, including many private schools not...

A convergence approach is utilized to examine deviations from the law of one price. Sample data are menu prices for eight identical products sold by international restaurant franchises in Mexico and the United States. The results suggest mean reverting behaviour in real exchange rate movements...

In this note it is shown that the expectation of the usual MLE estimator of the mean-reversion parameter in linear diffusion models does not exist. However, the moment does exist conditionally on the estimator of the autoregressive parameter in the discretized model being positive

This paper demonstrates the potential problem in using existing economics journal rankings to evaluate the research productivity of scholars by constructing a new ranking of economics journals and articles. Based on 2142 econometrics sample articles published from 2000 to 2005, our ranking...

We derive some new results on the expectation of quadratic forms in normal and nonnormal variables. Using a nonstochastic operator, we show that the expectation of the product of an arbitrary number of quadratic forms in noncentral normal variables follows a recurrence formula. This formula...

Overall journal rankings, which are generated with sample articles in different research fields, are commonly used to measure the research productivity of academic economists. In this article, we investigate a growing concern in the profession that the use of the overall journal rankings to...

The paper examines the relationship between economic growth, tax policy, and distribution of capital and labor ownership in a one-sector political-economy model of endogenous growth with productive government spending financed by a proportional tax on capital income. The analysis shows that...

Econometricians have recently been interested in estimating and testing the mean reversion parameter (κ) in linear diffusion models. It has been documented that the maximum likelihood estimator (MLE) of κ tends to over estimate the true value. Its asymptotic distribution, on the other...

The generalized method of moments (GMM) estimator is often used to test for convergence in income distribution in a dynamic panel set-up. We argue that though consistent, the GMM estimator utilizes the sample observations inefficiently. We propose a simple ordinary least squares (OLS) estimator...
