This paper explores sample size requirements for the estimation of SUR models by (two-stage) feasible generalized least squares, maximum likelihood and Bayesian methods. It is found that the sample size requirements presented in standard treatments of SUR models are incomplete and potentially...

It is now widely believed that Foreign Direct Investment (FDI) affects positively the productivity of individual enterprises in the host economy and this is a main argument in favour of FDI. Although China is the largest recipient of FDI after the USA, there has been little empirical research as...

Using examples drawn from two important papers in the recent literature on weak instruments, we demonstrate how observed experimental outcomes can be pro- foundly inuenced by the dierent conceptual frameworks underlying two exper- imental designs commonly employed when simulating simultaneous...

Poskitt and Skeels (2005) provide a new approximation to the sampling distribution of the IV estimator in a simultaneous equations model, the approximation is appropriate when the concentration parameter associated with the reduced form model is small. We present approximations to the sampling...

focus on the ability of the instrument set to predict a single endogenous regressor, even if there is more than one endogenous regressor in the equation of interest. We propose new measures of instrument relevance in the presence of multiple endogenous regressors, taking both univariate and...

This study examines the link between the health indicators and the environmental variables for a cross-section of countries widely dispersed in the economic development spectrum. While the environment and income are seen to have an inverted U-shaped relationship (Environmental Kuznets Curve...

It is common practice to examine empirical models in which one of the regressors is constructed as the weighted average or sum of a set of series that includes the dependent variable. Examples include models relating money and wealth, consumption and income and regional and national...

In recent years there has been considerable growth in ‘Fair Trade’ markets for several commodities, but most notably for coffee. We argue that coffee is grown under conditions that might well subject growers to the market power of intermediaries. Using an approach designed to evaluate the...

This paper discusses two ways to amend the optimal lending contract under asymmetric information studied in Clementi and Hopenhayn (2006) to change its long-run implications so that firm growth and exit driven by borrowing constraints exist in the long run. One way assumes that the entrepreneur...

This paper investigates the relationship between firm longevity and rat races in an environment where long-lived firms are operated by overlapping generations of short-lived players. We first present a complete information model in which workers in the young generation are offered employment...
