Specialization and the volume of trade: do the data obey the laws?
The core subjects of trade theory are the pattern and volume of trade: which goods are traded by which countries, and how much of those goods are traded. The first part of this paper discusses evidence on comparative advantage, with an emphasis on carefully connecting theoretical models with data analyses. The second part of the paper considers the theoretical foundations of the gravity model and reviews the small number of studies that have tried to test, rather than simply use, the implications of gravity. Both parts of the paper yield the same conclusion: we are still in the very early ...

Is Wall Street the Only Street in New York City?
Has Wall Street—the term for the securities industry that symbolizes New York City’s role as a global financial center—become less of a specialty for the city? In this post, we show that while the securities industry continues to play an outsized role in the New York City economy, the city’s job base has become somewhat more diversified since 1990. Diversification can be beneficial, as it makes a local economy less vulnerable to adverse shocks to its key industry. A recent example appears in a post by Bram and Orr showing that with Wall Street in a bit of a slump, nonfinancial ...

Distant Lending, Specialization, and Access to Credit
Small business lending has historically been very local, but distances between small businesses and their lenders have steadily increased over the last forty years. This paper investigates a new lending strategy made possible by distant small business lending: industry specialization. Using data on all Small Business Administration 7(a) loans from 2001-2017, we document a substantial increase in remote, specialized small business lenders, i.e., lenders that originate many distant loans and concentrate these loans within a small number of industries. These lenders target low-risk industries ...

Diversification and Specialization Across Urban Areas
Los Angeles is famous for the entertainment industry, San Jose for technology companies, and New York for the financial firms surrounding Wall Street. While each of these urban areas has a unique identity related to a particular sector of the economy, each is also, in fact, very diverse in its industrial composition. Urban areas differ in the extent to which they have a diverse set of industries or, conversely, the degree to which they are very specialized in a particular industry. Richmond Fed analysis supports previous research findings on the extent to which diversification or ...

The Expansion of Varieties in the New Age of Advertising
The last decades have seen large improvements in digital advertising technology that allowed firms to better target specific consumer tastes. This research studies the relationship among digital advertising, the rise of varieties, and economic welfare. We develop a model of advertising and varieties where firms choose the intensity of digital ads directed at specific consumers as well as traditional ads that are undirected. The calibrated model shows that improvements in digital advertising have driven the rise in varieties over time. Empirical evidence is presented using detailed micro data ...
