Multinational corporations are among the most innovative firms – and they account for the majority of the investment in innovation made around the world. Yet compared with the fragmentation of multinationals’ production across countries, investment in innovation by these firms is typically concentrated in one ‘headquarters’ country. The potential geographical mismatch between where knowledge is […]
We focus on research that concerns antitrust policy, economic regulation, and market design. Questions of interest include the following:
How should we regulate horizontal and/or vertical mergers? Is there a trade-off between short run market power and longer run investment incentives?
How should we respond to departures from the competitive ideal in markets; with imperfect information, that are highly concentrated, that are natural monopolies, or that generate externalities resulting from knowledge producing activities?
How should centralized markets (like health insurance exchanges, kidney exchanges, and school choice mechanisms) be organized?
What is the optimal design of auctions to procure services for the government, such as highway construction contracts, or to sell government assets, such as spectrum or mineral rights?
How can policy makers detect and deter collusion?
How should patent policy be designed?
Health care markets have become increasingly concentrated through mergers and acquisitions. Proponents of this consolidation cite several potential benefits, including lower costs due to economies of scale and better patient outcomes through coordinated care. Greater concentration may also result in higher prices or lower quality, however. In a recent paper, funded in part by a […]
Measuring the extent to which firms pass changes in their performance through to worker earnings is challenging. Our work uses US patent allowance decisions as “natural experiments” that lift a company’s labor productivity. We find robust evidence that variability in firm performance is an important causal determinant of worker pay in our sample of small […]
Suppose you happen to meet a very high earner. How does she typically make her money? Is she likely a human capitalist, in that she makes most of her income from her labor or other human capital? Or is she likely a financial capitalist, in that she makes most of her income from her portfolio […]
Throughout the world, the poor purchase less insurance (Rampini and Viswanathan 2016), and insurance markets are especially thin in the developing world. This could reflect supply-side problems: insurance is a complicated and highly regulated product, reliant on effective financial and legal institutions. Yet surprisingly, the binding constraint is often on the demand side. Across many […]
Every day, people make numerous decisions and judgments. Although these decisions differ in many dimensions – including the degree of deliberation, the number of people involved, and the stakes or consequences – many are sequential in nature. Research in a wide range of contexts has documented potential biases that can arise with such sequential decision-making, […]
Our study explores the importance of these two factors – technological innovation and regulatory arbitrage – in the New York City taxi market. Our study is part of an emerging body of research in economics that explores the implications of technological change in the transport sector. Another notable study that complements ours is by Nick […]
In 2019, Oregon and California became the first states to pass statewide rent control. Lawmakers in other states, including Colorado and Illinois, are considering repealing laws that limit cities’ abilities to pass or expand rent control. Rent control is already extremely popular around the San Francisco Bay Area: nine cities already impose rent control regulations, […]
So-called ‘vertical’ mergers between producers of TV channels and distributors of those channels are regular – and sometimes highly contested – events, both in the United States and elsewhere in the world. The attention that such mergers have attracted is partly due to the industry’s overwhelming reach and size: over 80% of the approximately 120 […]
Arthur Laffer, who was recently awarded the Presidential Medal of Freedom, is famous for sketching an inverted U-shaped diagram of the supposed trade-off between tax rates and tax revenues. The Laffer curve helps to characterize how firms as well as consumers respond to tax changes, and this research uses it to evaluate whether commodity taxes are an effective tool for financing government expenditure. Applying the idea to taxation of distilled spirits in Pennsylvania, where retail sales only take place through a state-run monopoly, the study shows how firms with market power change their pricing when taxes are cut and what that implies for state tax revenues.
