We study a consumer non-sequential search oligopoly model with search cost heterogeneity. We first prove that an equilibrium in mixed strategies always exists. We then examine the nonparametric identification and estimation of the costs of search. We find that the sequence of points on the...

In this paper, a method for estimating monotone, convex and log-concave densities is proposed. The estimation procedure consists of an unconstrained kernel estimator which is modi?ed in a second step with respect to the desired shape constraint by using monotone rearrangements. It is shown that...

We introduce a kernel-based estimator of the density function and regression function for data that have been grouped into family totals. We allow for a common intra-family component but require that observations from different families be in dependent. We establish consistency and asymptotic...

We consider nonparametric identification and estimation in a nonseparable model where a continuous regressor of interest is a known, deterministic, but kinked function of an observed assignment variable. This design arises in many institutional settings where a policy variable (such as weekly...

The analysis of auctions is an active area of research for both theoretical and empirical economists. This paper provides an overview of the literature relevant to the econometrics of auctions from a structural approach perspective. The structural approach is a framework to analyze auction data...

This article aims to estimate the informational rents earned by winning bidders in oil and gas exploration and production auctions in Brazil. We estimate the distributions of bids and bidders' private valuations using a nonparametric structural model and assuming independence and asymmetry...

We propose a consistent test for a linear functional form against a nonparametric alternative in a fixed effects panel data model. We show that the test has a limiting standard normal distribution under the null hypothesis, and show that the test is a consistent test. We also establish the...

Given the key role of the taxable income elasticity in designing an optimal tax system there are many studies attempting to estimate this elasticity. A problem with most of these studies is that strong functional form assumptions are used and that heterogeneity in preferences is not allowed for....
