Using a unique dataset of art auctions on eBay, we conduct an empirical analysis of the value of a seller's online reputation. Several aspects distinguish our work from most existing research. We analyze a heterogeneous panel data consisting of a large number of observations over a large period...

In this paper, we analyze a generalization of the evolutionary model of Kandori, Mailath, & Rob (1993) where the population is partitioned into groups and evolution takes place "in parallel" at the following two levels: (i) within groups, at the lower level; among groups, at the higher one....

This chapter discusses various methods that have been used to estimate structural models of search and survival models. Most of the focus is on using available data, usually on unemployment spell lengths and accepted wage o¤ers, to estimate the parameters of speci…c search models. In...

This paper investigates identification in structural search models that allow for the presence of measurement errors in wages. I show that the partial equilibrium search model with measurement error is not fully identified in general. I also specify sufficient conditions for identification of...

Credit card portfolios represent a significant component of the balance sheets of the largest US banks. The charge‐off rate in this asset class increased drastically during the Great Recession. The recent economic downturn offers a unique opportunity to analyze the performance of credit risk...

The Great Recession offers a unique opportunity to analyze the performance of credit risk models under conditions of economic stress. We focus on the performance of models of credit risk applied to risk-segmented credit card portfolios. Specifically, we focus on models of default and loss and...

In this paper we undertake an empirical study of advertising in an online auctions market, or, more precisely, advertising on eBay. The type of advertising that we consider works as follows: at the time of listing the item on eBay, sellers are offered the option of incurring an extra fee in...
