LOCALIZED KNOWLEDGE SPILLOVERS: EVIDENCE FROM THE AGGLOMERATION OF AMERICAN R&D LABS AND PATENT DATA
Supercedes 15-03 We employ a unique data set to examine the spatial clustering of private R&D labs. Instead of using fixed spatial boundaries, we develop a new procedure for identifying the location and size of specific R&D clusters. Thus, we are better able to identify the spatial locations of clusters at various scales, such as a half mile, 1 mile, 5 miles, and more. Assigning patents and citations to these clusters, we capture the geographic extent of knowledge spillovers within them. Our tests show that the localization of knowledge spillovers, as measured via patent citations, is ...

Consumer use of fraud alerts and credit freezes: an empirical analysis
Fraud alerts ? initial fraud alerts, extended fraud alerts, and credit freezes ? help protect consumers from the consequences of identity theft. At the same time, they may impose costs on lenders, credit bureaus, and, in some instances, consumers. We analyze a unique data set of anonymized credit bureau files to understand how consumers use these alerts. We document the frequency and persistence of fraud alerts and credit freezes. Using the experience of the data breach at the South Carolina Department of Revenue, we show that consumers who file initial fraud alerts or credit freezes likely ...

An empirical look at software patents
U.S. legal changes have made it easier to obtain patents on inventions that use software. Software patents have grown rapidly and now comprise 15 percent of all patents. They are acquired primarily by large manufacturing firms in industries known for strategic patenting; only 5 percent belong to software publishers. The very large increase in software patent propensity over time is not adequately explained by changes in R&D investments, employment of computer programmers, or productivity growth. The residual increase in patent propensity is consistent with a sizeable rise in the cost ...

Localized Knowledge Spillovers: Evidence from the Spatial Clustering of R&D Labs and Patent Citations
Patent citations are a commonly used indicator of knowledge spillovers among inventors, while clusters of research and development labs are locations in which knowledge spillovers are particularly likely to occur. In this paper, we assign patents and citations to newly defined clusters of American R&D labs to capture the geographic extent of knowledge spillovers. Our tests show that the localization of knowledge spillovers, as measured via patent citations, is strongest at small spatial scales and diminishes rapidly with distance. On average, patents within a cluster are about three to six ...

Consumers’ use of prepaid cards: a transaction-based analysis
The Payment Cards Center of the Federal Reserve Bank of Philadelphia and the Center for Financial Services Innovation conducted this research project using transaction-level data provided by Meta Payment Systems in an effort to develop a better understanding of how consumers use prepaid cards by examining their transaction behavior and the issuer revenue and cardholder costs generated by those transactions.

The agglomeration of R&D labs
This paper has been superseded by WP 15-03.<p>The authors document the spatial concentration of more than 1,000 research and development (R&D) labs located in the Northeast corridor of the U.S. using point pattern methods. These methods allow systematic examination of clustering at different spatial scales. In particular, Monte Carlo tests based on Ripley's (1976) K-functions are used to identify clusters of labs ? at varying spatial scales ? that represent statistically significant departures from random locations reflecting the underlying distribution of economic activity (employment). ...

An introduction to the economics of payment card networks
Open payment card networks typically coordinate the activities of thousands of financial institutions that issue cards, millions of retail locations that accept them, and several hundred million consumers that use them. This coordination can include the collective setting of certain prices and other controversial network rules. Such practices have recently come under the scrutiny of antitrust authorities in the U.S. and abroad. This paper provides a brief overview of the economics of the payment card industry, explaining some of the differences from the textbook model of competitive markets. ...

Urban density and the rate of invention
Economists, beginning with Alfred Marshall, have studied the significance of cities in the production and exploitation of information externalities that, today, we call knowledge spillovers. This paper presents robust evidence of those effects. We show that patent intensity?the per capita invention rate?is positively related to the density of employment in the highly urbanized portion of MAs. All else equal, a city with twice the employment density (jobs per square mile) of another city will exhibit a patent intensity (patents per capita) that is 20 percent higher. Patent intensity is ...

Business method patents and U.S. financial services
A decade after the State Street decision, more than 1,000 business method patents are granted each year. Yet only one in ten are obtained by a financial institution. Most business method patents are also software patents. ; Have these patents increased innovation in financial services? To address this question the author constructs new indicators of R&D intensity based on the occupational composition of financial industries. The financial sector appears more research intensive than official statistics would suggest but less than the private economy taken as a whole. There is considerable ...

Whither consumer credit counseling?
Bob Hunt outlines the history of credit counseling in the U.S. He also observes that, despite its long track record, the credit counseling industry is not without controversy. For example, in recent years, concerns about conflicts of interest and the emergence of a new type of credit counseling agency have triggered significant legislative and regulatory activity. Hunt notes that there is evidence that credit counseling organizations are effective in helping some consumers. However, he points out that the lack of formal research in this area makes it difficult to interpret information and a ...
