Path dependency in physician decisions

Lawrence Jin, Rui Tang, Han Ye, Junjian Yi, and Songfa Zhong

We examine path dependency in physician decisions in an emergency department setting, and find that physicians’ treatment decisions for the current and previous patients are positively correlated. We show that the positive autocorrelation is higher when the current patient is of greater medical uncertainty or more similar to the previous patient in terms of observed characteristics and when the physician is less experienced or more fatigued.

Exploiting Growth Opportunities: The Role of Internal Labor Markets

Giacinta Cestone, Chiara Fumagalli, Francis Kramarz, and Giovanni Pica

We explore how business groups use internal labor markets (ILMs) in response to changing economic conditions. We show that following the exit of a large industry competitor, group-affiliated firms expand and gain market share by increasing their reliance on the ILM to ensure swift hiring, especially of technical managers and skilled blue collar workers.

Evaluating the accuracy of counterfactuals: Heterogeneous survival expectations in a life cycle model

Jochem de Bresser

This paper shows that individual-level heterogeneity in survival expectations derived from subjective survey information improves the out-of-sample predictions of a dynamic model of retirement and saving. We consider three approaches to modelling survival: life tables, average subjective expectations and individual-specific estimates based on reported survival probabilities.

Market Power in Coal Shipping and Implications for U.S. Climate Policy

Louis Preonas

Economists have widely endorsed pricing CO2 emissions to internalize climate change-related externalities. Doing so would significantly affect coal, the most carbon-intensive energy source. However, U.S. coal markets exhibit an additional distortion: the railroads that transport coal to power plants can exert market power. This paper estimates how coal-by-rail markups respond to changes in coal demand. I identify markups in a major intermediate goods market using both reduced-form and structural methods.

Minimum Wage Employment Effects and Labor Market Concentration

José Azar, Emiliano Huet-Vaughn, Ioana Marinescu, Bledi Taska, and Till von Wachter

This paper shows that more highly concentrated labor markets experience more positive employment effects of the minimum wage. In the most concentrated labor markets, employment rises following a minimum wage increase. The paper establishes its main findings studying the effects of local minimum wage increases on a key low-wage retail sector, and using data on labor market concentration that covers the entirety of the United States with fine spatial variation at the occupation level.

Discrimination in Hiring: Evidence from Retail Sales

Alan M. Benson, Simon Board, and Moritz Meyer-ter-vehn

We propose a simple model of racial bias in hiring that encompasses three major theories: taste-based discrimination, screening discrimination, and complementary production. We derive a test that can distinguish these theories based on the mean and variance of workers’ productivity under managers of different pairs of races. We apply this test to study discrimination at a major U.S. retailer using data from 48,755 newly-hired commission-based salespeople.

``Many networks naturally form as people come together to form subgraphs, e.g. as coauthors of a paper, or other teams. This is the basis for a new, computationally tractable method of estimating network formation."
