In this paper we adapt the model of MacLeod (2007) to provide one way to formally implement some of Williamson's ideas regarding the effect of transactions costs upon employment relationship. We then explore the empirical implications of this model with a data set that measures job...

Background: Concerns have been raised about physician ownership of onsite advanced imaging equipment as allowed under Stark laws by the in-office ancillary service exception (IOASE). Methods: A web-based survey of orthopedic practices in the United States was used to assign a first date of...

We introduce a computationally tractable dynamic equilibrium model of the automobile market where new and used cars of multiple types (e.g. makes/models) are traded by heterogeneous consumers. Prices and quantities are determined endogenously to equate supply and demand for all car types and...

High transaction costs and thin participation plague water quality trading and prevent markets from delivering expected efficiency gains. Point sources generate a single pollutant, while nonpoint sources generate multiple, complementary pollutants. We develop a dynamic search model of...

We apply agency theory to the payroll records of a copper mine that paid a production bonus to teams of workers. As with most incentive pay used by firms, the bonus was simpler in form than the optimal contract that balances incentives, insurance, and free-riding. We explore whether transactions...

We document widespread violations of stochastic dominance in the one-month S&P 500 index options market over the period 1986-2002. These violations imply that a trader can improve her expected utility by engaging in a zero-net-cost trade. We allow the market to be incomplete and also imperfect...

This paper discusses the literature on the enforcement of incomplete contracts. It compares legal enforcement to enforcement via relationships and reputations. A number of mechanisms, such as the repeat purchase mechanism (Klein and Leffler (1981)) and efficiency wages (Shapiro and Stiglitz...

We study the interaction between monetary and fiscal policies in a Ramsey-Sidrauski model augmented with environmental capital. Equilibrium solutions are studied through the "Green Golden Rule". Despite the non-separability of money in utility and intertemporally nonseparable preferences, money...

The behaviour of limit order quotes and trading activity are studied using a unique and rich database that includes the identity of market participants from a fully automated derivatives market. The analysis is performed using transactions records for three aggregated trader types and three...

This paper investigates the impact of annual report readability on the corporate bond market. My findings indicate that in the US corporate bond market, firms with less readable annual reports tend to have higher credit spreads, higher credit spread volatilities, higher transaction costs, higher...
