This paper develops a model for demand-system estimations, whose coefficients are own-price Marshallian elasticities and elasticities of substitution between goods. The model satisfies the homogeneity, symmetry and, eventually, adding-up restrictions implied by consumer theory, and is primarily...

The literature on graphical models and the literature on identification pursue similar goals, but do not use entirely each other's results, because represent them in different languages. To ease the communication between these fields, I translate the most important theorems on identification of...

We consider the method of moments estimation of a structural equation in a panel dynamic simultaneous equations model under different sample size combinations of cross-sectional dimension, N, and time series dimension, T. Two types of linear transformation to remove the individual-specific...

H. Theil has made important contributions to the analysis of simultaneous-equations models. This paper gives an exposition of some closely related recent developments in microeconometrics, with a focus on efforts to develop robust methods for dynamic policy evaluation. We set the stage with a...

Existing estimation methods for multi-factor CES functions require limiting assumptions about the nature of technical change. We demonstrate how a system of equations and a fixed elasticity in the nested process can provide identification for more flexible specifications and for small data...

This paper studies simultaneous equations models for two or more discrete outcomes. These models may be incoherent, delivering no values of the outcomes at certain values of the latent variables and covariates, and they may be incomplete, delivering more than one value of the outcomes at certain...

New nonparametric methods that identify and estimate counterfactuals for individuals, when each is characterized by a vector of unobserved characteristics, are developed and applied to estimate systems of individual consumer demand and welfare measures. The unobserved characteristics are allowed...

We show that a manager who has to pick a variety at a store without being able to choose the price of products on the horizontally differentiated market with positive fixed costs of offering each product will always under-provide variety. Using the information on sales and availability of vodka...

This paper is a survey of the Italian bottled water industry that with quantitative approach relates the consumes or operative volumes of mineral water market based on the middle trend of temperatures, the consumed income per-capita and the trend of the population. We present the weight-OLS...
