The nature of energy and material resources in an endogenous growththeory framework isclarified. This involves three modifications of the conventionaltheory. Firstly, multiple feedbackmechanisms or “growth engines” are identified. Secondly, a productionfunction distinguishesbetween resource...

Research on the presence of consumer racial discrimination in the baseball labor and memorabilia markets has produced contradictory empirical results. While studies of baseball salaries-find no evidence of discrimination, Nardinelli and Simon (1990) and Andersen and La Croix (1991) use data from...

Associated with every popular nonlinear estimation method is at least one "artificial" linear regression. We define an artificial regression in terms of three conditions that it must satisfy. Then we show how artificial regressions can be useful for numerical optimization, testing hypotheses,...

The paper aims to use the Granger causality to deduce the structure of recursive model. Manipulating data from five sectors of Moroccan economy we form causal chain between endogenous variables to build a recursive system. The findings exhibit two group, the first one consists of agriculture,...

In this note we propose a general testing procedure for parametric models based on Bartlett Identities. A well-know example is the Information Matrix test, which is based on the Bartlett Identity of order 1. The Identities are shown to induce a sequence of testable restrictions on the data...
