China is virtually unique globally in that transactions prices of vacant land are observed regularly there. When Yongheng Deng
, Joe Gyourko
, and Jing Wu
construct land price indexes for 35 major Chinese cities, they find that average land values have skyrocketed in many markets, not just those near the coast, over the last nine years. Their estimates show double-digit compound average annual growth in real, constant-quality land values, with the period 2009-10 seeing even larger price increases. The amount of land coming to market for sale also has been increasing sharply in recent years.

, Fabian Lange
, and Matthew Notowidigdo
conducted an experiment in which fictitious resumes, which differed only in whether a job applicant was unemployed and for how long, were sent to real job postings in 100 U.S. cities. They found that the likelihood of receiving a callback for an interview decreased significantly with the length of a fictitious worker's unemployment spell, especially during the first eight months. That effect -- called duration dependence -- is stronger when the labor market is tighter. These results suggest that employers use the length of an unemployment spell as a signal of productivity, but that signal is less informative in weak labor markets.

Using data from the 1972-1993 Annual Survey of Manufactures, researchers Michael Greenstone
, John List
, and Chad Syverson
estimate the effects of air quality regulations on the total factor productivity (TFP) of manufacturing plants. They find that stricter air quality regulations are associated with a decline in TFP of roughly 2.6 percent: ozone regulations have particularly large negative effects on productivity, but carbon monoxide regulations appear to increase measured TFP, especially among refineries. After correcting for other influences -- including price increases, output declines, and sample selection of plants that survived over the entire period -- they estimate a 4.8 percent decline in TFP for polluting plants in regulated areas. In economic terms, this corresponds to an annual cost of roughly $21 billion, or nearly 9 percent of manufacturing sector profits in this period.

The processes required to develop and produce natural gas from shale rock use a great deal of water and require underground, high-pressure, chemical injections. The risks associated with leasing one’s land to gas-exploration-and-production companies are especially important for those who depend on groundwater as a source of drinking water. Using data on property sales from 2004 to 2009 in an area with shale gas wells -- Washington County, Pennsylvania -- Lucija Muehlenbachs
, Elisheba Spiller
, and Christopher Timmins
find that house prices are positively affected by the drilling of a shale gas well unless the property depends on groundwater. Such properties are negatively affected: by itself, groundwater risk reduces property values by up to 24 percent.

, Stephen Dimmock
, and Scott Weisbenner
find that donations to higher education - especially capital donations designated for university endowment or buildings - are positively and significantly correlated with the average income and house values in the university's home state. They also find that donations increase when a university suffers a large negative shock to its endowment relative to its operating budget.

The Great Recession brought high rates of unemployment that have been slow to recede. When Edward Lazear
and James Spletzer
analyze labor market data, they find that the increased rates of unemployment in recent years cannot be explained by structural changes, industrial or demographic shifts, or a mismatch of skills with job vacancies. Instead, their findings suggest that unemployment is being caused by cyclical factors that are simply more pronounced during the current recession than in prior recessions.

examine whether green building procurement policies which apply only to municipal buildings accelerate the use of green building practices by private-sector developers. The researchers find that the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) standard for sustainable building practices diffuses nearly twice as quickly among private-sector developers in municipalities that adopt government-oriented green building procurement policies as in a matched control sample of cities of similar size, demographics, and environmental preferences. In addition, they find more LEED adoption among "neighbor cities" - those bordering the city that adopted a green building policy. They suggest that government purchasing policies may break deadlocks that emerge when coordinated investments are required to adopt a common standard, and that this in turn may stimulate the private-sector market for the goods and services targeted by government green procurement policies.

identify 70 credit booms -- episodes in which credit to the private sector rises significantly above its long-run trend -- that occurred in 61 emerging and industrial countries between 1960 and 2010. They find that in the upswing phase, credit booms are associated with periods of economic expansion, rising equity and house prices, real currency appreciation, and widening external deficits. Credit booms also tend to be synchronized internationally. They are similar in duration and magnitude in the industrial and the emerging economies, and often follow surges in capital inflows, gains in total factor productivity, and financial reforms. Credit booms are often followed by banking or currency crises, and they are far more common with managed than with flexible exchange rates.

Using data on violent incidents in the Philippines between 2001 and 2008, Eli Berman
, Joseph Felter
, Ethan Kapstein
, and Erin Troland
find a positive relationship between local economic activity and insurgent violence. This finding appears to support the "predation theory" of insurgent violence, in which a higher level of economic activity offers greater opportunities for insurgents to extract rents. This result does not support several other theories that try to explain insurgent violence, notably those that highlight the opportunity cost of individual participation in an insurgency, which rises with the level of economic activity, and those that posit that greater economic activity generates support for the established government.

Firms advertise in order to stimulate demand for their products, so you would expect them to aggressively promote their high-profit-margin products. A rise in profit margins should expand advertising by a lot, and advertising should be highly counter-cyclical. However, Robert Hall
finds that from 1950-2010 advertising was somewhat pro-cyclical: that is, the ratio of advertising spending to private GDP falls when the economy contracts. While wages decline in recessions and the labor share of income falls, the observed behavior of advertising refutes the hypothesis that these changes are associated with a rise in profit margins. Hall concludes that there must be another factor that lowers the wage without raising profit margins, perhaps a rise in a product-market friction with the same effect as an increase in sales taxes.
