Homotheticity induces a dramatic statistical bias in the estimates of the intratemporal and intertemporal substitutions. I find potent support in favor of nonhomotheticity in aggregate consumption data, with nondurable goods being necessities and durable goods luxuries. I obtain the...

In a Yaari-Blanchard overlapping generations endowment economy, and drawing on the equivalence between Radner (R) and Arrow-Debreu (AD) equi- libria, we prove that equilibrium AD prices have an explicit representation as a double integral equation. This allows for an analytic characterization of...

A general equilibrium model, that incorporates endogenous production and local housing markets, is developed in order to explain the price relationship among human capital, housing, and stocks, and to uncover the role of housing in asset pricing. Housing serves as an asset as well as a durable...

The Japanese economy experienced a substantial increase and a subsequent crash in land and stock prices in the 1980s and 90s. I use a neoclassical growth model to determine how much of these asset price movements can be accounted for by the observed changes in fundamentals of the Japanese...

This paper shows that unregulated decentralized equilibrium is viable under increasing returns technologies in an overlapping generations model of production with cash-in-advance constraints. We also demonstrate that the model exhibits both the Tobin effect and the reverse Tobin effect.

Ken Arrow (1998) asks, “What has economics to say about racial discrimination?” He replies – entirely correctly – that racial “segregation within an industry – that is, firms with either all black or all white labor forces” – may be explained by economic theory, but “the...

We study the problem of finding necessary and sufficient conditions that guarantee global uniqueness of equilibria in a pure exchange economy. We show that for every economy to have a unique equilibrium it is necessary and sufficient that (i) there are no critical economies and (ii) a compact...

Canonical analysis of the classical general equilibrium model demonstrates the existence of an open and dense subset of standard economies that possess fully-revealing rational expectations equilibria. This paper shows that the analogous result is not true in urban economies under appropriate...
