We consider nonparametric identification in models of differentiated products markets, using only market level observables. On the demand side we consider a nonparametric random utility model nesting random coefficients discrete choice models widely used in applied work. We allow for...

We propose a simple nonparametric mixtures estimator for recovering the joint distribution of parameter heterogeneity in economic models, such as the random coefficients logit. The estimator is based on linear regression subject to linear inequality constraints, and is robust, easy to program...

Agents in two-sided matching games vary in characteristics that are unobservable in typical data on matching markets. We investigate the identification of the distribution of these unobserved characteristics using data on who matches with whom. The distribution of match-specific unobservables...

We present new identification results for nonparametric models of differentiated products markets, using only market level observables. We specify a nonparametric random utility discrete choice model of demand allowing rich preference heterogeneity, product/market unobservables, and endogenous...

Almost all recent US firm commitment IPOs between $20 million and $80 million in proceeds have been charged an underwriting spread of exactly 7%, while in the early 1980s only 25% of IPOs faced such clustering at exactly 7% [Chen and Ritter (2000)]. Such clustering, or specifically, the apparent...

We investigate the effects of forward looking behavior in technology adoption. The setup is an overlapping generation model where agents choose between two alternative networks taking in consideration both the installed base and the expected base. The latter element is the distinctive feature of...

Employee stock options differ substantially from traded options. Most expire within 90 days of the termination of employment, and are forfeited if the employee leaves before vesting. The major accounting standards boards are in agreement that options should be expensed, but companies have...

This paper presents a new data set of individual residential property transactions in England. The main novelty of the data is the record of all listing price changes and all offers made between initial listing and sale agreement. We establish a number of stylized facts pertaining to the...

Empirical studies of price competition typically analyze the direct effects of market structure, cost, and local demand on prices; this approach has been applied widely to studies of bank deposit rates. However, the theory of the banking firm suggests that substitutability between sources of...

This paper presents and investigates a new data set of individual residential property transactions in England. The main novelty of the data is the record of all listing price changes and all offers made on a property, as well as all the visits by potential buyers for a subset of the properties....
