Theoretically, if firms face a regulatory per-customer quantity limit, they should have an incentive to discriminatively charge high-demand customers higher prices and make them just willing to buy a quantity equal to the limit. In the U.S. residential mortgage industry, mortgages with...

Many successful franchise chains directly own a positive fraction of stores --- a structure referred to as plural form. We propose that this ownership structure is chosen as a commitment not to expropriate franchisees. The theoretical model is based on an empirical analysis of contract and...

In this paper, we examine new Internet ecosystem strategies through comprehensive OECD PATSTAT patent data analyses focusing on mobile operating system software firms. We also describe current patent disputes between mobile hardware firms and mobile operating system software firms in the US and...

This paper examines the relationship between business dynamics and employment effects in 320 U.S. Metropolitan Statistical Areas (MSA). Much of the theoretical work on industry dynamics focuses on the role of noisy selection and incomplete information on entry and survival. We extend this...

We document that, after remaining almost constant for almost 30 years, real labor productivity at U.S. restaurants surged over 15% during the COVID pandemic. This surge has persisted even as many conditions have returned to pre-pandemic levels. Using mobile phone data tracking visits and...

This paper evaluates the recent literature claiming that the US economy has generally become less competitive causing the US economy to perform poorly and that lax antitrust policy is one important reason for the decline in economic performance. Although there certainly are empirical facts...

We present evidence that the negative effect of the China shock on US manufacturing employment is lower for industries that use services inputs more intensively. Different potential mechanisms for this finding are analyzed. This reveals significant heterogeneity across different types of...

This study uses survey data and Instrumental Variables (IV) methods to assess whether in the US, the prices of credit cards (annual percentage rates, APRs) reflect the short and long-term risks of cardholders (measured as unpaid credit card debt in the previous year, outstanding debt and FICO...

We develop a stylized model that allows us to estimate a value-added measure for nursing homes ("SNFs") which accounts for patient selection both into and out of a SNF. We use the model, together with detailed data on the physical and mental health of about 6 million Medicare SNF patients...
