What are the macroeconomic consequences of changing aggregate lending standards in residential mortgage markets, as measured by loan-to-value (LTV) ratios? In a structural VAR, GDP and business investment increase following an expansionary LTV shock. Residential investment, by contrast, falls, a...

Does time-varying business volatility affect the price setting of firms and thus the transmission of monetary policy into the real economy? To address this question, we estimate from the firm-level micro data of the German IFO Business Climate Survey the impact of idiosyncratic volatility on the...

In recent years, the learnability of rational expectations equilibria (REE) and determinacy of economic structures have rightfully joined the usual performance criteria among the sought-after goals of policy design. Some contributions to the literature, including Bullard and Mitra (2001) and...

Expected exchange rate changes are determined by interest rate differentials across countries and risk premia, while unexpected changes are driven by innovations to macroeconomic variables, which are amplified by time-varying market prices of risk. In a model where short rates respond to the...

We study markets where innovators can sell ideas to entrepreneurs, who may be better at implementing them. These markets are decentralized, with random matching and bargaining. Entrepreneurs hold liquid assets lest potentially profitable opportunities may be lost. We extend existing models of...

This paper studies the long run effects of monetary policy in a micro-founded model with trading frictions and endogenous market segmentation. Agents must pay a fixed cost to participate in a centralized liquidity market. By endogenizing the participation decision, this model endogenizes the...

We study how the use of judgement or add-factors in macroeconomic forecasting may disturb the set of equilibrium outcomes when agents learn using recursive methods. We isolate conditions under which "exuberance equilibria" exist in standard macroeconomic environments. These equilibria may...
