The US spends more than 4 trillion dollars per year on health care, largely conducted by private providers and reimbursed by insurers. A major concern in this system is overbilling, waste and fraud by providers, who face incentives to misreport on their claims in order to receive higher...

Using only 34 published tables, we reconstruct five variables (census block, sex, age, race, and ethnicity) in the confidential 2010 Census person records. Using the 38-bin age variable tabulated at the census block level, at most 20.1% of reconstructed records can differ from their confidential...

We use variation in exposure to victimization of 1,537 households of eastern Congo for each year of 1990-2013 to examine the formation of preferences to participate in armed groups. In this context, most armed groups are Congolese militia, whose objective is fighting foreign armed groups. We...

Violent conflicts, particularly at election times in Africa, are a common cause of instability and economic disruption. This paper studies how firms react to electoral violence using the case of Kenyan flower exporters during the 2008 post-election violence as an example. The violence induced a...

The Cultural Revolution deprived Chinese students of the opportunity to receive higher education for 10 years when colleges and universities were closed from 1966-1976. We examine the human capital cost of this loss of education on subsequent innovation by firms, and ask if it impacted firms...

Can efforts to eradicate inequality in wealth and education eliminate intergenerational persistence of socioeconomic status? The Chinese Communist Revolution in the 1950s and Cultural Revolution from 1966 to 1976 aimed to do exactly that. Using newly digitized archival records and contemporary...

There were substantial fluctuations in the numbers of American overseas travelers, especially before World War II. These fluctuations in travel around the robust, long term upward trend are the focus of this paper. We first identify those fluctuations in the raw data and then try to explain the...

The French Revolution of 1789 had a momentous impact on neighboring countries. The French Revolutionary armies during the 1790s and later under Napoleon invaded and controlled large parts of Europe. Together with invasion came various radical institutional changes. French invasion removed the...

There is a paucity of facts about the effects of the recent military "Surge" on conditions in Iraq and whether it is paving the way for a stable Iraq. Selective, anecdotal and incomplete analyses abound. Policy makers and defense planners must decide which measures of success or failure are most...

Assassinations are a persistent feature of the political landscape. Using a new data set of assassination attempts on all world leaders from 1875 to 2004, we exploit inherent randomness in the success or failure of assassination attempts to identify assassination's effects. We find that, on...
