As an aid to interpreting the results of height-by-age studies this paper investigates the relationship between average height and per capita income. The relationships among income, nutrition, medical care, and height at the individual level suggest that average height is nonlinearly related to...

We explore the impact of rising incomes at the top of the distribution on spatial sorting patterns within large U.S. cities. We develop and quantify a spatial model of a city with heterogeneous agents and non-homothetic preferences for neighborhoods with endogenous amenity quality. As the rich...

We construct and calibrate a model of the world economy in which countries' opportunities to develop depend on their trade with advanced economies. Trade opportunities in turn depend on the relative population of the advanced and developing world. As developing countries become advanced, they...

It is widely hypothesized that incomes in wealthy countries are insulated from environmental conditions because individuals have the resources needed to adapt to their environment. We test this idea in the wealthiest economy in human history. Using within-county variation in weather, we estimate...

The paper first assesses regional and ethnic group differences in social trust and memberships in both Canada and the United States. The ethnic categories people choose to describe themselves are as important as regional differences, but much less important than education, in explaining...

The American Recovery and Reinvestment Act (ARRA) was the US government's fiscal response to the Great Recession. An important component of ARRA's $796 billion proposed budget was $318 billion in fiscal assistance to state and local governments. We examine the historical experience of federal...

State business climate indexes capture state policies that might affect economic growth. State rankings in these indexes vary wildly, raising questions about what the indexes measure and which policies are important for growth. Indexes focused on productivity do not predict economic growth,...

We examine the golden age of U.S. innovation by undertaking a major data collection exercise linking historical U.S. patents to state and county-level aggregates and matching inventors to Federal Censuses between 1880 and 1940. We identify a causal relationship between patented inventions and...
