We study the effect of physician incentives in an HMO network. Physician incentives are controversial because they may induce doctors to make treatment decisions that differ from those they would chose in the absence of incentives. We set out a theoretical framework for assessing the degree to...

This paper examines the role that work incentives play in the determination of work hours. Following previous research by Lang (1989), we use a conventional efficiency wage model to analyze how firms respond to worker preferences regarding wage-hours packages. We find that when workers are...

Economists generally agree that the immediate and direct effect of a binding minimum wage law is to move firms backward along the demand curve for low skill workers. However, this prediction of worker displacement depends critically on a model of firm behavior that abstracts from problems of...

This paper presents an incentive-based dual labor market model. Three implications of the model are emphasized. First, in equilibrium, there is an excess supply of workers to primary jobs. Second, when demand is uncertain, firms may choose a mix of primary and contingent workers to perform the...

We analyze the role of search frictions in the market for commercial health insurance. Frictions increase the cost of insurance by enabling insurers to set price above marginal cost, and by creating incentives for inefficiently high levels of marketing. Frictions also lead to price dispersion...

Many goods and services can be readily provided through a series of unconnected transactions, but in health care close coordination over time and within care episodes improves both health outcomes and efficiency. Close coordination is problematic in the US health care system because the...

We study the economics of employment relationships through theoretical and empirical analysis of an unusual set of firms, large law firms. Our point of departure is the "property rights" approach that emphasizes the centrality of ownership's legal rights to control important, non-human assets of...

This paper incorporates the sociological concept of group norms' into an economic analysis of pay systems. We use a behavioral microeconomic model and a unique survey of medical groups to examine the theoretical and empirical relationship between group norms and incentive pay. Our findings...

Recently developed effort regulation models argue that labor markets are segmented because of differences in the technology of supervision across firms. primary jobs pay above market clearing wages because these jobs are difficult to monitor. Secondary jobs, in contrast, pose no monitoring...

How does team structure affect productivity? We address this question with an application to healthcare by examining the teams that primary care physicians (PCPs) assemble when they refer patients to specialists. Our theoretical model analyzes how PCPs trade off costly coordination against...
