This study examines the spatial distribution of Muslim societies shedding light on its geographic origins. The empirical analysis conducted across countries, virtual countries, and ethnicities establishes that geographic inequality and proximity to pre-Islamic trade routes are fundamental...

The lowest level of government in sub-Saharan Africa is often a cadre of chiefs who raise taxes, control the judicial system and allocate the most important scarce resource - land. Chiefs, empowered by colonial indirect rule, are often accused of using their power despotically and inhibiting...

The Great Depression of the 1930s and the Great Credit Crisis of the 2000s had similar causes but elicited strikingly different policy responses. It may still be too early to assess the effectiveness of current policy responses, but it is possible to analyze monetary and fiscal policies in the...

The housing boom that preceded the Great Recession was due to an increase in credit supply driven by looser lending constraints in the mortgage market. This view on the fundamental drivers of the boom is consistent with four empirical observations: the unprecedented rise in home prices and...

What are the stylized facts that characterize the dynamics of credit booms and the associated fluctuations in macro-economic aggregates? This paper answers this question by applying a method proposed in our earlier work for measuring and identifying credit booms to data for 61 emerging and...

We show that firms’ idiosyncratic volatility obeys a strong factor structure and that shocks to the common factor in idiosyncratic volatility (CIV) are priced. Stocks in the lowest CIV-beta quintile earn average returns 5.4% per year higher than those in the highest quintile. The CIV factor...

We present a DSGE model where firms optimally choose among alternative instruments of external finance. The model is used to explain the evolving composition of corporate debt during the financial crisis of 2008-09, namely the observed shift from bank finance to bond finance, at a time when the...

The ability of corporations to raise external equity finance varies with macroeconomic conditions, suggesting that the cost of equity issuance is time-varying. Using cross sectional data on U.S. publicly traded firms, we construct an empirical proxy of an aggregate shock to the cost of equity...

Why are financial crises associated with a sustained rise in unemployment? We develop a tractable model with frictions in both credit and labor markets to study the aggregate and micro-level implications of a credit crunch--i.e., a tightening of collateral constraints. When we simulate a credit...

Is there a link between loose monetary conditions, credit growth, house price booms, and financial instability? This paper analyzes the role of interest rates and credit in driving house price booms and busts with data spanning 140 years of modern economic history in the advanced economies. We...
