The promise of biotechnology has been tantalizingly just beyond reach for a number of years. Biotechnology is often touted as a means of increasing agricultural production, improving sustainability, and offering more nutritious food to the public. Promises of increased yield — more food for a...

The Supreme Court has held that Article II’s vesting of executive power in the President, who must “take Care that the Laws be faithfully executed,” provides the President with the power to remove most principal executive officers at will. The Court has also held that Humphrey’s Executor...

In 1987 the federal government permitted states to raise the speed limit on their rural interstate roads, but not on their urban interstate roads, from 55 mph to 65 mph for the first time in over a decade. Since the states that adopted the higher speed limit must have valued the travel hours...

This paper analyzes how gasoline tax rates are related to the time workers in the United States spend commuting by private car, public transport, or with other physical modes of transport. Our identification strategy relies on both between-state differences and time variations in gasoline taxes....

Traffic fatalities are the leading cause of mortality in the United States despite being preventable. While several policies have been introduced to improve traffic safety and their effects have been well documented, the role of transitory health shocks or situational factors at explaining...

Preferences for transport activities are often considered only in terms of time and money. Whilst congestion in automobile traffic increases costs by raising trip durations, the same is less obvious in public transport (PT), especially rail-based. This has lead many economic analyses to conclude...

We test how a reduction in travel cost affects the rate and direction of scientific research. Using a fine-grained, scientist-level dataset within chemistry (1991-2012), we find that after Southwest Airlines enters a new route, scientific collaboration increases by 50%, an effect that is...

Drinking-and-driving remains a leading cause of preventable mortality and morbidity in the United States, yet reliable estimates of its prevalence and the increased risk it imposes on other road users remain elusive. The tendency of respondents to under-report illicit and socially stigmatized...

The value of time determines relative prices of goods and services, investments, productivity, economic growth, and measurements of income inequality. Economists in the 1960s began to focus on the value of non-work time, pioneering a deep literature exploring the optimal allocation and value of...
