Our research uses data from multiple archival sources to examine substitution among armored (tank-intensive), infantry (troop-intensive), and airborne (also troop-intensive) military units, as well as mid-war reorganizations of each type, to estimate the marginal cost of reducing U.S. fatalities...

This paper investigates the long-run effects of climate change on conflict by examining cooling from 1400-1900 CE, a period that includes most of the Little Ice Age. We construct a geo-referenced and digitized database of conflicts in Europe, North Africa, and the Near East from 1400-1900, which...

Survey data is used to estimate the impact of physical attractiveness rated by the interviewer as well as by the respondent on employment probability and labor income of men and women. In addition to mean linear and non-linear effects on earnings, simultaneous quantile regressions are applied to...

We apply an innovative technique to allow for differential effects of physical appearance and self-confidence across the wage distribution, as traditional methods can confound opposing effects at either end of the wage distribution. Comparing the effects of beauty and confidence measures in two...

We measure the impact of individuals' looks on their life satisfaction or happiness. Using five data sets from the U.S., Canada, the U.K., and Germany, we construct beauty measures in different ways that allow putting a lower bound on the true effects of beauty on happiness. Personal beauty...

Armed conflicts, natural disasters and infrastructure projects continue to force millions into migration. This is especially true for developing countries. After World War II, about 8 million ethnic Germans experienced a similar situation when forced to leave their homelands and settle within...

How do health crises affect election results? We combine a panel of election results from 1893 1933 with spatial heterogeneity in excess mortality due to the 1918 Influenza to assess the pandemic's effect on voting behavior across German constituencies. Applying a dynamic...

Observations on munition workers are organized to examine the relationship between their output each week, their working hours and days each week, and their working hours and days in adjacent weeks. The hypothesis is that workers need to recover from work and a long working week results in...

Can counter-propaganda by a foreign democratic country help to overthrow an authoritarian military regime? And if so, what are the mechanisms through which this happens? We analyze these questions in the context of the Nazi-fascist occupation of Italy during WWII. We study the effect of BBC...

This paper addresses the question to which extent the complementarity between educationand training can be attributed to differences in observable characteristics, i.e. to individual,job and firm specific characteristics. The novelty of this paper is to analyze previouslyunconsidered...
