Gravity as both fact and theory is one of the great success stories of recent research on international trade, and has featured prominently in the policy debate over Brexit. We first review the facts, noting the overwhelming evidence that trade tends to fall with distance. We then introduce some...

This study finds that even small unexpected supply shocks propagate downstream through production networks and are amplified by firms with short-term financial constraints. The unexpected 2011 increase in the tax on imports purchased with foreign-sourced trade credit is examined using data...

We postulate a nonlinear DSGE model with a financial sector and heterogeneous households. In our model, the interaction between the supply of bonds by the financial sector and the precautionary demand for bonds by households produces significant endogenous aggregate risk. This risk induces an...

Are entrepreneurs liquidity constraint? Using quasi-random housing wealth variation resulting from communist era decisions, we argue yes, as we find that wealthier East Germans are more likely to become self-employed after reunification. In the literature, no such strong relationship was found...

We estimate the effects of monetary policy on price-setting behavior in administrative micro data underlying the German producer price index. We find a strong degree of monetary non-neutrality. After expansionary monetary policy, the mass of additional price adjustments is economically small and...

Peer-to-business lending refers to online platforms facilitating loans from individuals to small and medium-sized enterprises (SMEs). We conjecture that easy-to-understand risk ratings conveyed by the platform play a pronounced role in influencing the borrowing success of SMEs and that more...

Various forms of social learning and network effects are at work on crowdfunding platforms, giving rise to informational and payoff externalities. We use novel entrepreneur-backer data to study how these externalities shape funding dynamics, within and across projects. We find that backers...

We suggest an explanation for the existence of “mission drift”, the tendency for Microfinance Institutions (MFIs) to lend money to wealthier borrowers rather than to the very poor. We focus on the relationship between MFIs and external funding institutions. We assume that both the MFIs and...
