Competitors’ Reactions to Big Tech Acquisitions: Evidence from Mobile Apps

Since 2010, Google, Apple, Facebook, Amazon, and Microsoft (GAFAM) have acquired more than 400 companies. Competition authorities did not scrutinize most of these transactions and blocked none.

We empirically study the competitive effects ...

The Hidden Homeownership Welfare State: An International Long-Term Perspective on the Tax Treatment of Homeowners

Welfare is traditionally understood through social security decommodifying labor markets or social investment policies. In the domain of housing, however, welfare for homeowners is largely hidden in the tax codes’ fiscal exemptions. Based on a content analysis of legislation, this paper introduces a novel yearly database of 37 countries between 1910 and 2020 to uncover the “hidden welfare state” of ...

Impact of Mexico's Energy Reform on Consumer Welfare

We study the impact of Mexico's energy reform on the welfare of electricity, liquified petroleum gas, and gasoline consumers between 2010 and 2018. We utilize micro-level data to estimate income and price elasticities. Comparative statics are used to determine subsidy and price influences on consumer surplus. A counterfactual is used to simulate the industry's behavior under non-reform parameters. ...

We investigate patterns in common ownership networks between firms that are active in the U.S. pharmaceutical industry for the period 2004–2014. Our main findings are that “brand firms”—that is, firms that have research and development capabilities and launch new drugs—exhibit relatively dense common ownership networks with each other that further increase significantly in density over time, whereas ...

Lender-Specific Mortgage Supply Shocks and Macroeconomic Performance in the United States

This paper provides evidence for the propagation of idiosyncratic mortgage supply shocks to the macroeconomy. Based on micro-level data from the Home Mortgage Disclosure Act for the 1990-2016 period, our results suggest that lender-specific mortgage supply shocks affect aggregate mortgage, house price, and employment dynamics at the regional level. The larger the idiosyncratic shocks to newly issued ...
