Di erentiated Products Demand Systems from a Combination of Micro and Macro Data : Autos Again 1

چکیده
In this paper, we exploit new sources of data to estimate a detailed product-level demand system for new passenger vehicles. We use three data sources: on products, on the U.S. population of households and on the match between households and product choices. We show that the householdchoice data solves some, but not all, of the traditional problems in estimating di erentiated products demand systems. Our empirical results provide rich detail on the patterns of product substitution in the industry.

Di erentiated Products Demand Systems from a Combination ofMicro and Macro Data : The New Car Market 1
In this paper, we exploit new sources of cross-sectional data to estimate a detailed product-level demand system for new passenger vehicles. We use four data sources: on the characteristics of products, on the attributes of the U.S. population of households, on the match between the rst and second vehicle choices of the household, and on the match between households attributes and rst choice ve...
متن کاملDifferentiated Products Demand Systems from a Combination of Micro and Macro Data: The New Car Market
In this paper, we consider how rich sources of information on consumer choice can help to identify demand parameters in a widely-used class of differentiated products demand models. Most importantly, we show how to use “second-choice” data on automotive purchases to obtain good estimates of substitution patterns in the automobile industry. We use our estimates to make out-of-sample predictions ...
متن کاملDifferentiated Products Demand Systems from a Combination of Micro and Macro Data
In this paper we provide an algorithm for estimating characteristic based demand models from alternative data sources, and apply it to new data on the market for passenger vehicles. We find that, provided care is taken in constructing the demand system and rich enough data are available, the characteristic based model can both rationalize existing results and provide realistic out of sample pre...
متن کاملA Unied Approach to Estimating Demand and Welfare⇤
The measurement of price changes, economic welfare, and demand parameters is currently based on three disjoint approaches: macroeconomic models derived from time-invariant utility functions, microeconomic estimation based on time-varying utility (demand) systems, and actual price and real output data constructed using formulas that di�er from either approach. The inconsistencies are so deep tha...
متن کاملGravity-Compensated Robust Control for Micro-Macro Space Manipulators During a Rest to Rest Maneuver
Many space applications require robotic manipulators which have large workspace and are capable of precise motion. Micro-macro manipulators are considered as the best solution to this demand. Such systems consist of a long flexible arm and a short rigid arm. Kinematic redundancy and presence of unactuated flexible degrees of freedom, makes it difficult to control micro-macro manipulators. This ...
