Policymakers often use the output gap, a noisy signal of economic activity, as a guide for setting monetary policy. Noise in the data argues for policy caution. At the same time, the zero bound on nominal interest rates constrains the central bank's ability to stimulate the economy during...

This paper investigates the efficiency of household investment decisions in a unique dataset containing the disaggregated wealth and income of the entire population of Sweden. The analysis focuses on two main sources of inefficiency in the financial portfolio: underdiversification of risky...

I compare nominal GDP level targeting to flexible inflation targeting in a small New Keynesian model subject to the zero lower bound on nominal policy rates. First, I study the performance of optimal discretionary policies. I find that, for a standard calibration, inflation targeting under...

We develop an equilibrium model for origination fees charged by mortgage bro- kers and show how the equilibrium fee distribution depends on borrowers' valua- tion for their loans and their information about fees. We use non-crossing quantile regressions and data from a large subprime lender to...

A standard, no-recourse mortgage contract does not adjust when the value of the underlying collateral falls. Consequently, shocks that lower house prices may trigger one of the necessary conditions for default: negative equity. A common alternative contract attempts to prevent default by...

A string of theoretical papers shows that the non-exclusivity of credit contracts generates important negative contractual externalities. Employing a unique dataset, we identify how these externalities affect the supply of credit. Using internal information on a creditor’s willingness to lend,...

Does the Church Tower Principle, i.e. geographical proximity between borrowing firm and lending bank, matter in credit risk management? If so, the bank might expose itself to a greater risk by lending to distant firms and should therefore respond by rationing them harder. In this paper we...

We propose to incorporate cross-sectional heterogeneity into structural VARs. Heterogeneity provides an additional dimension along which one can identify structural shocks and perform hypothesis tests. We provide an application to bank runs, based on microeconomic deposit market data. We impose...

In this paper we empirically study interactions between real activity and the financial stance. Using aggregate data we examine a number of candidate measures of the financial stance of the economy. We find strong evidence for substantial spillover effects on aggregate activity from our...

The new Basel II regulation contains a number of new regulatory features. Most importantly, internal ratings will be given a central role in the evaluation of the riskiness of bank loans. Another novelty is that retail credit and loans to small and medium-sized enterprises will receive a special...
