Economists wish to use data on matches to learn about the structural primitives that govern sorting. I show how to use equilibrium data on who matches with whom for semiparametric estimation of match production functions in many-to-many, two-sided matching games with transferable utility....

Can directed technical change be used to combat climate change? We construct new firm-level panel data on auto industry innovation distinguishing between "dirty" (internal combustion engine) and "clean" (e.g. electric and hybrid) patents across 80 countries over several decades. We show that...

We document a strong correlation in the brand of automobile chosen by parents and their adult children, using data from the Panel Study of Income Dynamics. This correlation could represent transmission of brand preferences across generations, or it could result from correlation in family...

This paper analyzes "attribute-based regulations," in which regulatory compliance depends upon some secondary attribute that is not the intended target of the regulation. For example, in many countries fuel-economy standards mandate that vehicles have a certain fuel economy, but heavier or...

Projection bias is the tendency to overpredict the degree to which one's future tastes will resemble one's current tastes. We test for evidence of projection bias in two of the largest and most important consumer markets - the car and housing markets. Using data for more than forty million...

New car fleet fuel economy, weight and engine power have changed drastically since 1980. These changes represent both movements along and shifts in the "fuel economy/weight/engine power production possibilities frontier". This paper estimates the technological progress that has occurred since...

There is convincing evidence that the Internet has lowered the prices paid by some consumers in established industries, for example, term life insurance and car retailing. However, current research does not reveal much about how using the Internet lowers prices. This paper answers this question...

The number of different car and light truck models produced in North America has increased enormously over the last decades. The data suggests that producing this increased variety of vehicles is associated with a productivity penalty. We show that manufacturers can adopt complementary...

Are location-specific factors--such as the education and attitude of the local workforce, supplier networks, institutional infrastructure, and local "culture"--important for understanding persistent heterogeneities among firms? We address this question in the context of the automobile industry....

We analyze optimal policy when consumers of energy-using durables undervalue energy costs relative to their private optima. First, there is an Internality Dividend from Externality Taxes: aside from reducing externalities, they also offset distortions from underinvestment in energy efficiency....
