The correlation across US states in house price growth increased steadily between 1976 and 2000. This paper shows that the contemporaneous geographic integration of the US banking market, via the emergence of large banks, was a primary driver of this phenomenon. To this end, we first...

The authors study a dynamical model of interconnected firms which allows for certain market imperfections and frictions, restricted here to be myopic price forecasts and slow adjustment of production. Whereas the standard rational equilibrium is still formally a stationary solution of the...

When a bank experiences an adverse shock to its equity capital, one way to return to target leverage is to sell assets. The price impact of the fire sale may impact other institutions with common exposures, resulting in contagion. We propose a simple framework that accounts for this effect. This...

We investigate whether the geographic dispersion of a firm affects corporate decision making. Our findings suggest that social factors work alongside informational considerations to make geography important to corporate decisions. We show that (i) geographically dispersed firms are less employee...

[fre] Ce papier examine les différents thèmes en management du risque qui se trouvent mis au devant de la scène par la crise des « subprimes ». Les institutions financières doivent réfléchir aux améliorations de leur gouvernance du risque non seulement dans ses aspects techniques, mais...

This paper documents a steady increase in the average correlation of house price growth across US states over the 1976-2006 period and shows that this phenomenon can be explained in large part by the geographic integration of the banking market over this period. We theoretically derive an...

We model the link between inequality, lack of political commitment, and ex-cessive risk taking. If politicians cannot commit to a long-term tax schedule, increasing returns to tax avoidance induce the middle class to take on non rewarded ?nancial risk despite risk aversion. Electoral pressure...
