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 paper analyzes the effects of several policy instruments to mitigate financial bubbles generated in the banking sector. We augment a New Keynesian macroeconomic framework by endogenizing boundedly-rational expectations on asset values of loan portfolios and allow for interbank trading. We...

This paper explores the impact of credit market on the entrepreneurs and demand for credit in a credit constrained economy and the resultant impact on the capital flows. In standard trade models the capital flows across countries are explained as a result of the rate of return differentials due...

We compare integration of economic, matching and networking markets. There can be losers from integration in all three cases, but their relative numbers depend on the type of market. There can be many losers from integration of pure exchange economies. There are relatively few losers from...

This paper uses loan application-level data from a peer-to-peer lending platform to study the risk-taking channel of monetary policy. By employing a direct ex-ante measure of risk-taking and estimating the simultaneous equations of loan approval and loan amount, we are the first to provide...

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...

Flexible repayment schedules allow borrowers to invest in profitable yet risky projects, but practitioners fear they erode repayment morale. We study repayment choices in rigid and flexible loan contracts that allow discretion in repayment timing. To separate strategic repayment choices from...

We explore the intertwined dynamics of asset prices and the macroeconomy in a Behavioural model of Credit Cycles (BCC) characterized by a credit friction à la Kiyotaki and Moore and heterogeneous expectations cum heuristic switching à la Brock and Hommes. This behavioural approach allows to...

In many countries entrepreneurship is promoted through tax reductions for small businesses and by various government support schemes. We analyze the effects of such policies to subsidize small businesses in a setting where both the risk-return characteristics of the selected innovation project...

We integrate a market microstructure model with an exchange competition model with entry in which exchanges supply technological services that enhance market participation, and have market power. We find that technological services can be strategic substitutes or complements in platform...
