The t-test of an individual coefficient is used widely in models of qualitative choice. However, it is well known that the t-test can yield misleading results when the sample size is small. This paper provides some experimental evidence on the finite sample properties of the t-test in models...

This paper reviews the literature on Bartlett and Bartlett-type corrections. It focuses on the corrections to the likelihood ratio, score and Wald test statistics. Three different Bartlett-type corrections which are equivalent to order 1/n, n being the sample size, are compared through...

In this paper, we examine the robust Wald test statistic for SUR systems with adding up restrictions where the same explanatory variables are present in all equations and where heteroskedasticity and/or autocorrelation of unknown forms may be present. For this case, the coefficients are usually...

It is now well known that standard asymptotic inference techniques for instrumental variable estimation perform very poorly in the presence of weak instruments. Specifically, standard asymptotic techniques give spuriously small standard errors, leading investigators to accept apparently tight...

In this paper, we propose a fix to the size distortions of tests for structural parameters in the simultaneous equations model by computing critical value functions based on the conditional distribution of test statistics. The conditional tests can then be used to construct informative...

In this study, we introduce statistics for testing neglected nonlinearity using the extreme leaning machines introduced by Huang, Zhu, and Siew (2006, Neurocomputing) and call them ELMNN tests. The ELMNN tests are very convenient and can be widely applied because they are obtained as byproducts...

Foreign direct investments are generally considered as one of the factors with positive influence on the economic development of countries in which this investments flow. In evaluating the impact of foreign direct investment on development, however, a key question is whether foreign direct...

Research was conducted to find out the effects of exchange rate variability, terms of trade, competitiveness and gross domestic product on the dominant export crop of Ethiopia, coffee. This study employs annual time series data (1992–2010) and uses the autoregressive distributive lag...

This article uses the model proposed by Chiappori, Levitt, and Groseclose to test for mixed-strategy Nash equilibria in a game between a kicker and a goalkeeper in the situation of a penalty kick in soccer. The main contribution of this article is to develop an alternative testing methodology on...

This paper shows that a test for heteroskedasticity within the context of classical linear regression can be based on the difference between Wald statistics in heteroskedasticity-robust and nonrobust forms. The test is asymptotically distributed under the null hypothesis of homoskedasticity as...
