The Economics of Debt Collection: Enforcement of Consumer Credit Contracts
Creditors often outsource the task of obtaining repayment from defaulting borrowers to third-party debt collectors. We argue that by hiring third-party debt collectors, creditors can avoid competing in terms of their debt collection practices. This explanation fits several empirical facts about third-party debt collection and is consistent with the evidence that third-party debt collectors use harsher debt collection practices than original creditors. Our model shows that the impact of third-party debt collectors on consumer welfare depends on the riskiness of the pool of borrowers and ...

Antitrust issues in payment card networks: can they do that? should we let them?
Although people still use cash to pay for goods and services, the trend is toward payment cards. In the U.S., payment card networks coordinate the activities of thousands of financial institutions, millions of retail locations, and several hundred million consumers. This coordination may 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. In "Antitrust Issues in Payment Card Networks: Can They Do That? Should We Let Them?" Bob Hunt describes the ...

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 ...

IDENTITY THEFT AS A TEACHABLE MOMENT
SUPERCEDES 14-28. This paper examines how a negative shock to the security of personal finances due to severe identity theft changes consumer credit behavior. Using a unique data set of linked consumer credit data and alerts indicating identity theft, we show that the immediate effects of fraud on consumers are typically negative, small, and transitory. After those immediate effects fade, identity theft victims experience persistent, positive changes in credit characteristics, including improved risk scores (indicating lower default risk). We argue that these changes are consistent with ...

The Agglomeration of American Research and Development Labs
We employ a unique data set to examine the spatial clustering of about 1,700 private research and development (R&D) labs in California and across the Northeast corridor of the United States. Using these data, which contain the R&D labs? complete addresses, we are able to more precisely locate innovative activity than with patent data, which only contain zip codes for inventors? residential addresses. We avoid the problems of scale and borders associated with using fixed spatial boundaries, such as zip codes, by developing a new point pattern procedure. Our multiscale core-cluster approach ...

Patent reform: a mixed blessing for the U.S. economy?
The 1980s represented a period of dramatic change in the design and enforcement of U.S. intellectual property law. Many of these changes were adopted in the hopes of stimulating private research and development and improving the technological competitiveness of American industries. This article examines the effects of an especially important aspect of these changes: many more inventions qualify for patent protection than before. While it seems logical that making patents easier to obtain will encourage more inventive activity, economic analysis reveals this is not always true, and it is less ...

Patentability, industry structure, and innovation.
To qualify for a patent, an invention must be new, useful, and nonobvious. This paper presents a model of sequential innovation in which industry structure is endogenous and a standard of patentability determines the proportion of all inventions that qualify for protection. There is a unique patentability standard, or inventive step, that maximizes the rate of innovation by maximizing the number of firms engaged in R&D. Surprisingly, this standard is more stringent for industries disposed to innovate rapidly. If a single standard is applied to heterogeneous industries, it will encourage ...

Innovation in financial services and payments
Rapid innovation is changing the array of financial services and payment options available to customers. To examine the driving forces behind the surge of innovation and the adoption of new technology, the Payment Cards Center and the Research Department of the Federal Reserve Bank of Philadelphia hosted a conference on ?Innovation in Financial Services and Payments? on May 16-17 of this year. ; This document provides a summary of the presentations and discussions during the two day conference event.

Dynamic Pricing of Credit Cards and the Effects of Regulation
We construct a two-period model of revolving credit with asymmetric information and adverse selection.In the second period, lenders exploit an informational advantage with respect to their own customers. Those rents stimulate competition for customers in the first period. The informational advantage the current lender enjoys relative to its competitors determines interest rates, credit supply, and switching behavior. We evaluate the consequences of limiting the repricing of existing balances as implemented by recent legislation. Such restrictions increase deadweight losses and reduce ex ante ...

Financial Consequences of Severe Identity Theft in the U.S.
We examine how a negative shock from severe identity theft affects consumer credit market behavior in the United States. We show that the immediate effects of severe identity theft on credit files are typically negative, small, and transitory. After those immediate effects fade, identity theft victims experience persistent increases in credit scores and declines in reported delinquencies, with a significant proportion of affected consumers transitioning from subprime-to-prime credit scores. Those consumers take advantage of their improved creditworthiness to obtain additional credit, ...
