Research methods

This paper applies revealed preference theory to the nonparametric statistical analysis of consumer demand.

Moment conditions are derived for dynamic linear panel data models with linear individual specific effects in the mean and multiplicative individual effects in the conditional ARCH type variance function.

Quadratic Engel curves, welfare measurement and consumer demand

The authors propose a method to test for liquidity constraints which relies on using the within period marginal rate of substitution condition as a benchmark to evaluate the intertemporal Euler equation.

Both direct utility function and Frisch cost function representations of demand system rank are derived.

The Hicks-Leontief composite commodity theorem permits aggregation of sets of goods that have identical price movements into composite groups of goods, each of which can be treated like a single good for demand analysis.

The generalized method of moments (GMM) estimation technique is discussed for count data models with endogenous regressors.

This note gives a theorem concerning choice of covariate distribution.

In this paper we consider estimation of the autoregressive error components model.

This paper develops a new separability concept - latent separability.

We use two-and three-period overlapping-generations (OLG) models to show that entries and exits (births and deaths) produce a relationship between aggregate consumption growth and the interest rate that is fundamentally different from the individual Euler equation for consumption.
