The presence of different prices in different databases for the same securities can impair the comparability of research efforts and seriously damage the management decisions based upon such research. In this study we compare the six major sources of corporate Credit Default Swap prices: GFI,...

This paper presents a theory of liquidity where we explicitly model the liquidity of the security as a choice variable, which enables the manager raising the funds to screen for 'deep pocket' investors, i.e. these that have a low likelihood of a liquidity shock. By choosing the degree of...

Financial institutions have both investors and customers. Investors, such as those who invest in stocks and bonds or private/public-sector guarantors of institutions, expect an appropriate risk-adjusted return in exchange for the financing and risk-bearing that they provide. Customers of a...

From 1986 through 1997 the entry-level market for American gastroenterologists was organized by a centralized clearinghouse. Before, and since, it has been conducted via a decentralized market in which appointment dates have unraveled to well over a year before the start of employment. The...

Work schedules play an important role in utilizing labor in organizations. In this study of emergency department physicians in shift work, schedules induce two distortions: First, physicians "slack off" by accepting fewer patients near end of shift (EOS). Second, physicians distort patient care,...

This paper develops a framework for estimating preferences in two-sided matching markets with non-transferable utility using only data on observed matches. Unlike single-agent choices, matches depend on the preferences of other agents in the market. I use pairwise stability together with a...
