study data on the sovereign bond exposures of a large set of European banks during the 2010-11 sovereign debt crisis. They use these exposures to estimate the potential spillovers that could occur during bank deleveraging precipitated by sovereign downgrades or defaults, and they document a correlation between their estimates of bank vulnerability and the equity drawdowns experienced by European banks in 2010 and 2011. They further find that size caps, or forced mergers among the most exposed banks, do not reduce systemic risk very much. On the other hand, modest equity injections, if distributed appropriately between the most systemic banks, can cut the vulnerability of the banking sector to deleveraging by more than half.

analyze data from the Panel Study of Income Dynamics on family background and county of residence in early childhood, and on later adult health and economic outcomes. They find that access to the U.S. Food Stamp Program, which was rolled out across U.S. counties at various times between 1961 and 1975, was correlated with outcome measures decades later. They conclude that access to food stamps in childhood leads to a significant reduction in the incidence of obesity, high blood pressure, and diabetes. Women whose families received food stamps are also more economically self sufficient as adults than women of similar background whose families did not receive them.

study the diffusion over time and space of 20 major technologies in a sample of 161 countries over the last 140 years. They are specifically interested in the presence of cross-country correlations in the adoption of technology. They find that technology diffuses more slowly to locations that are farther away from leaders in the adoption of technology, especially when the countries in question are rich, and when the distance between them is measured along the south-north dimension. The researchers conclude that geography plays a significant role in determining technology diffusion across countries.

analyze data on broad-based merit aid scholarship programs introduced in 15 U.S. states along with census data on all 24-to-32 year olds in the United States from 1990 to 2010. They find that eligibility for merit aid programs slightly increases the propensity of state natives to live in-state, and that it raises in-state enrollment in public colleges among those in their late twenties. However, the effects of merit aid are small, which suggests that most of the spending on these programs is received by individuals who do not change their educational or migration behavior.

The Golden Quadrilateral (GQ) highway project upgraded the quality and width of 5,846 km of roads in India and sought to improve the connection of four major cities: Delhi, Mumbai, Chennai, and Kolkata. Ejaz Ghani
, Arti Goswami
, and Bill Kerr
find that manufacturing firms located 0-10 km from GQ experienced increases in plant productivity, which was not the case for plants located 10-50 km from the road. They also show that the GQ project led to a stronger sorting of land-intensive industries from nodal districts to non-nodal districts located on the GQ network, and that it helped to spread economic activity to moderate-density districts and intermediate cities.

Over the past 25 years the structure of wages in West Germany has become more unequal. David Card
, Jörg Heining
, and Patrick Kline
ask whether this change is attributable to greater variation in the "portable" person-specific component of wages, or to greater variation in the wage component that is associated with the firm for which a particular employee works. Their data reveal that both components have contributed to growing inequality: the gap between consistently high- and low-wage workers has grown, but the gap between good and bad jobs has also grown.

finds that the employment-to-population ratio among those aged 16-64 declined from 74 percent in 2000 to less than 72 percent in 2007, an historic reversal from its upward trend over the prior 30 years. The decline was greater among younger and less educated men and women, and was especially pronounced among unmarried and childless women. Moffitt finds that about half of the change for men can be explained by declining wage rates and changes in non-labor income and family structure, but the decline among women is more difficult to explain.

Proposition 209 banned the use of racial preferences in admissions at California's public colleges and was followed by a 4.4 percent increase in minorities' graduation rates. Peter Arcidiacono
, Esteban Aucejo
, Patrick Coate
, and Joseph Hotz
find that Proposition 209 was associated with better matches between students and campuses, which explain about 20 percent of the overall graduation rate increase. They estimate that changes in the selectivity of enrolled students explain between 34 and 50 percent of the increase, while schools doing more to help retain students and see them graduate can explain between 30 and 46 percent.

The property tax is the least popular tax in the United States and the only major tax whose revenues have declined as a share of income, perhaps because it is so salient. Marika Cabral
and Caroline Hoxby
show that in areas in which the property tax is less salient -- because a larger proportion of property owners are having taxes paid from escrow accounts, rather than being directly involved in the process of writing checks -- property taxes are higher, but property tax revolts are less likely to occur.

combine linguistic maps on the spatial distribution of groups within countries with satellite images of light density at night to construct estimates of inequality in well-being (and/or public goods provision) across ethnic lines for a large number of countries. They find that ethnic inequality is weakly correlated with the standard measures of income inequality and is strongly negatively correlated with per capita GDP across countries. When they analyze within-country, across-district variation in 17 Sub-Saharan countries, along with household survey data, they find that those from the same ethnic group report worse living conditions, lower levels of formal education, and inadequate access to basic public goods when they reside in districts characterized with a higher degree of ethnic group inequality.
