We investigate how owners of durable goods respond to a once-for-all unanticipated shock in a housing market that was in a stationary state prior to, and after the shock. We determine the circumstances under which the landlord will: 1) abandon his building immediately; 2) run down his building...

The first note treats the transition from a barter economy to a monetary one from the viewpoint of the theory of clubs. The second note demonstrates the possibility that in general equilibrium the use of a less costly means of exchange man not be beneficial to every agent. The third note shows...

This paper develops an extremely general procedure for performing a wide variety of model specification tests by running artificial linear regressions. Inference may then be based either on a Lagrange Multiplier statistic from the procedure, or on conventional asymptotic t or F tests based on...

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,...

Artificial linear regressions often provide a convenient way to calculate test statistics and estimate covariance matrices. This paper discusses one family of these regressions, called "double-length" because the number of observations in the artificial regression is twice the actual number of...
