It is well known that movements in lending rates are asymmetric; they rise quickly and sharply, but fall slowly and gradually. Not known is the fact that the asymmetry is stronger the less developed a country's financial system is. This new fact is here documented and explained in a model with an...

Official development assistance is a key source of external finance in many developing countries. A striking feature of these aid flows is their positive correlation with the business cycle of recipient countries. This pattern is puzzling in that it reinforces recipients' already strong and...

In this paper, I explore how optimal aggregate dynamics can be shaped by the presence of moral hazard in unemployment insurance. I also analyze the optimal provision of unemployment insurance and the implications for the amount of cross-sectional heterogeneity. The economy that I consider embeds...

This paper develops a model of banking frictions and banking risk, the importance of which is highlighted by the recent Global Financial Crisis (GFC). As a sort of systemic risk, changes in banking risk lead to fluctuations in aggregate economic activity. We propose a model-based approach to...

Systemic risk builds up during booms in an economy featuring asymmetric information in asset markets, where investors' hidden effort choices endogenously determine asset quality distribution. Higher asset prices during booms induce more investors to sell their assets, which lowers their...

Asymmetric information is crucial for understanding the disruption of the supply of credit. This paper studies a dynamic economy featuring asymmetric information and resulting adverse selection in credit markets. Entrepreneurs seek loans from banks for projects, but asymmetric information about...

I consider a real business cycle model in which agents have private information about an idiosyncratic shock to their value of leisure. I consider the mechanism design problem for this economy and describe a computational method to solve it. This is an important contribution of the paper since...

This paper studies the effect of inter-entrepreneurial productivity variation on investment under asymmetric information and signalling in the credit market. When productivity is not sufficiently dispersed, safe-type entrepreneurs face borrowing constraints and might under- or over-invest...

We assess how survey expectations impact production and pricing decisions on the basis of a large panel of German firms. We identify the causal effect of expectations by matching firms with the same fundamentals but different views about the future. The probability to raise (lower) production is...
