Marriage Institutions and Sibling Competition

Using data from Bangladesh, India, Nepal, and Pakistan, Tom Vogl examines one of the effects of arranged marriage: the rivalry that it cultivates among sisters. In countries where arranged marriages are common, parents typically want to marry off their oldest daughter first. Because girls in these countries leave school when they marry and thus face limited earnings opportunities when they reach adulthood, the number of sisters one has, and whether they are older or younger, has consequences for a woman's well-being over her life time. Vogl finds that having younger sisters is correlated with a girl leaving school earlier, leading to lower literacy, and to being matched to a husband with less education and a less-skilled occupation. He finds that these cross-sister pressures on marriage age are common throughout the developing world, although their effect on schooling costs varies by country.

The Value of Bosses

Edward Lazear, Kathryn Shaw, and Christopher Stanton analyze measures of daily productivity for over 23,000 workers, matched to nearly 2,000 bosses (supervisors) over the five years from June 2006 through May 2010. The workers' productivity is measured by computer for a single "technology-based service" job -- such jobs include retail sales clerk, movie theater concession stand employee, in-house IT specialist, airline gate agent, call center worker, technical repair worker, or other jobs in which an employee is logged into a computer while working. The researchers find that bosses vary in quality, in terms of their effect on workers' productivity: replacing a boss who is in the lower 10 percent of quality with one who is in the upper 10 percent of quality increases a team’s total output by about the same amount as adding one worker to a nine member team. The results imply that the average boss is about 1.75 times as productive as the average worker.

Do Patent Pools Encourage Innovation?

Patent pools allow competing firms to combine their patents for the same technology as if they are a single firm. Ryan Lampe and Petra Moser analyze over 75,000 patent applications across 20 industries between 1921 and 1948, encompassing the period when New Deal regulations made it easier for firms to pool their patents. They find a 16 percent decline in patenting in response to the creation of a patent pool, which occurred in fields where competing firms were combining patents for substitute technologies.

Is U.S. Economic Growth Over?

Robert Gordon asks whether it is reasonable to assume that economic growth will continue, especially for the United States, at a pace similar to that of the past 250 years, which encompassed the Industrial Revolution, various advances in transportation, and the rise of the computer and related inventions. He concludes that even if innovation were to continue at the rate of the two decades before 2007, six "headwinds" -- demography, education, inequality, globalization, energy/environment, and the overhang of consumer and government debt -- would reduce long-term growth to half or less of its 1860-2007 annual rate of 1.9 percent. His estimates suggest that for all but the top one percent of the income distribution, future growth in consumption per capita could fall below 0.5 percent per year for decades to come.

Local Ethnic Communities Provide Channels of Influence

By analyzing customs and port authority data on the international shipments of all U.S. publicly-traded firms over the past 17 years, Lauren Cohen, Umit Gurun, and Christopher Malloy find a causal link between local networks of ethnic residents and a firm's trade links. For example, a firm in a largely Indian area of New Jersey is more likely to trade with India. They also find that firms that exploit such networks experience stronger future sales growth and profitability, and their risk-adjusted stock returns outperform other importers and exporters by 5 to 7 percent per year. They conclude that immigrants play a surprisingly large economic role as conduits of information for firms in their new countries.

Evidence from the Home Affordable Modification Program

The 2009 Home Affordable Modification Program (HAMP), which was one of the federal government's responses to the foreclosure crisis, provided financial incentives to mortgage servicers to renegotiate mortgage loans. Sumit Agarwal, Gene Amromin, Itzhak Ben-David, Souphala Chomsisengphet, Tomasz Piskorski, and Amit Seru estimate that the HAMP program will reach only about one-third of its targeted households. The reason for this shortfall is that a few large servicers have been renegotiating mortgages at half the rate of other mortgage lenders, possibly because of limited organizational capacity. Experience with this program suggests that it is not possible for the government to quickly influence firm behavior with financial incentives.

Medicaid Eligibility and Teenage Mortality

Several early expansions of Medicaid extended eligibility for this publicly provided health insurance only to children born after September 30, 1983. If their family incomes were at or just below the poverty line, children had nearly five more years of Medicaid eligibility if they were born just after the cutoff date than if they were born just before it. Bruce Meyer and Laura Wherry find that these program expansions had a particularly large effect on Medicaid eligibility for black children, and that these expansions were associated with a a 13-18 percent decrease in the mortality rate of black teens born after September 30, 1983.

An Analysis of the Fed's Term Auction Facility

From December 2007 to March 2010, the U.S. Federal Reserve System used the Term Auction Facility (TAF) to inject funds into the banking system. Effi Benmelech finds that foreign banks accounted for 58 percent of the TAF lending, with a total amount of $2.2 trillion as compared to $1.6 trillion for U.S. banks. Most of the banks and financial institutions that pledged asset-backed securities as collateral were foreign – primarily European – banks. These European banks were more likely to bid for TAF money because they were more severely affected by the financial crisis, given the mismatch between their assets and liabilities: the data suggest that foreign banks had to borrow from the Federal Reserve Bank to meet their dollar-denominated liabilities.

Grading Government Efficiency

As one way of measuring government efficiency in various nations, Alberto Chong, Rafael La Porta, Florencio Lopez-de-Silanes, and Andrei Shleifer mailed letters to non-existent business addresses in 159 countries (10 per country). All of the countries are signatories of the International Postal Convention, which requires that undeliverable letters be returned to sender. The researchers found that about 60 percent of the letters were returned to the return address in the United States, but that there were large differences across nations in the percentage returned. For example, all of the letters that were mailed to Canada, Norway, and Germany were returned, while none of the letters sent to Tajikistan, Cambodia, and Russia were returned. They conclude that this “return rate” provides a simple measure of one aspect of government efficiency, and that it is influenced both by technology and management quality.

Optimism in Budget Forecasts

Jeff Frankel and Jesse Schreger find that government budget forecasts tend to be overly optimistic, especially among the Eurozone countries. Particularly during booms, and when they have large contemporaneous budget deficits, governments’ real GDP forecasts are similarly over-optimistic. Eurozone members often exceed the 3 percent cap on budget deficits, but almost never forecast that they will do so in the future. National fiscal rules help to counteract the wishful thinking that seems to come with euro membership, because when governments violate the 3 percent cap, these rules apparently constrain them from making unrealistic forecasts. The existence of an independent fiscal institution producing budget forecasts at the national level reduces the over-optimism bias of forecasts made when the countries are in violation of the 3 percent cap.
