This survey outlines various models used to analyze the impact of taxation on the firm's leverage decision. The models incorporate: i) differential taxation of household from a progressive tax system; ii) loss offsetting under the corporate tax; iii) managerial incentive to avoid moral hazard;...

This paper seeks to distinguish between principles upon which testing of statistical hypotheses may be based and the practical methods which these principles generate. Seber's (1964) conclusion, that the Wald, Lagrange Multiplier and Likelihood Ratio Principles all lead to the same test...

It is argued that the general formulation of point-optimal tests, as summarized in King (1988): i) makes use of a benchmark which is excessively stringent; ii) fails to integrate the method with traditional testing methods; iii) uses data to form a specific null hypothesis; iv) offers no...

The geometry of least squares is exploited to develop an exact test of the Hausman (1978) type of a linear hypothesis. This leads to necessary and sufficient conditions for the equivalence of Hausman and classical tests. The geometrical theory is then extended to the general problem of...

This paper distinguishes between the principles upon which testing statistical hypotheses may be based and the practical methods these principles generate. Seber's (1964) conclusion that the Wald, Lagrange Multiplier and Likelihood Ratio Principles all yield the same test statistic for linear...

This paper considers the relations between the classical identifiability test statistic and corresponding significance tests of the coefficients of endogenous variables of one equation of a linear interdependent system in the context of Generalized Classical Linear (GCL) estimation. Known...

This paper is concerned with the problem of testing one form of covariance structure against another in a normal linear regression. All point-optimal tests recently proposed by King and his associates can be interpreted as special cases of the Cox test for non-nested hypotheses. This provides a...
