We develop a new form of the information matrix test for a wide variety of statistical models, and present full details for the special case of univariate nonlinear regression models. Chesher (1984) showed that the implicit alternative of the information matrix test is a model with random...

The cluster robust variance estimator (CRVE) relies on the number of clusters being large. A shorthand "rule of 42'' has emerged, but we show that unbalanced clusters invalidate it. Monte Carlo evidence suggests that rejection frequencies are higher for datasets with 50 clusters proportional to...

Confidence intervals based on cluster-robust covariance matrices can be constructed in many ways. In addition to conventional intervals obtained by inverting Wald (t) tests, the paper studies intervals obtained by inverting LM tests, studentized bootstrap intervals based on the wild cluster...

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...

The local power of test statistics is analyzed by extending the notion of Pitman sequences to sequences of data-generating processes (DGPs) that approach the null hypothesis without necessarily satisfying the alternative hypothesis. Under quite general conditions, the three classical test...

It is often argued that the dependent variable in money demand functions is really the price level, the money stock itself being exogenous. A recent approach which stresses the theme is the "buffer stock" hypothesis, in which money supply shocks explicitly appear in the demand for money...

This paper investigates the costs of residential height restrictions, using a numerically solvable general equilibrium model based on residential location theory. Time and money costs of travel are treated separately. Household demand recreational land and structure and actual construction cost...

This paper proves the existence of general equilibrium in a large class of models which include taxes and similar distortions. A wide range of taxes are compatible with the existence of general equilibrium. These include taxes on income, consumption, and production which may discriminate among...

The widely used Cochrane-Orcutt and Hildreth-Lu procedures for estimating the parameters of a linear regression model with first-order serial correlation typically ignore the first observation. An alternative maximum likelihood procedure is recommended in this paper. This procedure is preferable...
