This research challenges previous findings regarding the robustness of the African growth dummy by expanding the list of variables to include those suggested by Easterly and Levine (1998) and Sachs and Warner (1997b). Using the Bayesian Averaging of Classical Estimates approach, this paper...

An explicit finite difference scheme for the numerical solution of the diffusion equation on a rectangular region, subject to a non-local boundary condition in the form of a double integral which simulates the specificaion of mass in a curved region is developed. The scheme, is based on the...

Linear regression analysis is important in many fields. In the analysis of simulation results, a regression (meta)model can be applied, even when common pseudorandom numbers are used. To test the validity of the specified regression model, Rao (1959) generalized the F statistic for lack of fit,...

A product often requires inspection on more than one characteristic. The traditional method determines inspection specifications for each characteristic independently. This practice ignores the interactions among characteristics in determining the disposition of an item, and prohibits tradeoffs...

This paper discusses the best way to formulate and estimate a dynamic econometric model when interest focuses mainly upon its long-run properties. Using results derived for the more general context of transformed regression models, it is shown how point estimates and the standard errors of...

In a recent paper, Plosser, Schwert and White (1982) proposed a general test for model misspecification based on a comparison of estimates of the model in levels and first-differences. We demonstrate that this test is equivalent to a certain F test for omitted variables. The latter test has...
