The aim of this note is to present a root-N consistent estimator for the regression coefficients in a fixed-effects panel data sample selection model that has one selection equation and two regression equations. Other than the condition that the error terms satisfy a control function type of...

This paper explores the secular decline in the employment share in agriculture as a result of productivity growth in the agricultural sector. I study an equation that states that employment share in agriculture is determined by the subsistence constraint and productivity in agriculture. Given...

This paper uses the multivariate unobserved components model with phase shifts to analyse the interaction of interest rates, output, asset prices and credit in the US. We find close linkages amongst cyclical fluctuations in the variables.

Using a unique data set from the Bank of Canada, this paper presents the frequency domain analysis of a causal relationship between the Canada/US dollar exchange rate movements and currency order flows. The evidence shows that the existence as well as the direction of causality depends on the...

New estimates of an aggregate long-term production function for the post-war U.S. economy are reported. The results indicate that this long-term aggregate production function exhibits a slight but statistically significant increasing returns to scale. Since virtually all econometric growth...

This note elaborates on a potential misinterpretation of the convergence speeds that are associated with the beta-convergence effect. Practitioners and certain researchers often commit the common error of using the results from the logarithmic measure of the income gap to interpret the speed of...

We suggest to use car sale prices from internet advertisements for measuring economic inequality between and within German regions. Our estimates of regional income levels and Gini indices based on advertisements are highly positively correlated with the official figures.
