On the Welfare Effects of Credit Arrangements

Staff Working Paper 2012-43 Jonathan Chiu, Mei Dong, Enchuan Shao
This paper studies the welfare effects of different credit arrangements and how these effects depend on the trading mechanism and inflation. In a competitive market, a deviation from the Friedman rule is always sub-optimal. Moreover, credit arrangements can be welfare-reducing, because increased consumption by credit users will drive up the price level so that money users have to reduce consumption when facing a binding liquidity restraint.

Money and Price Posting under Private Information

Staff Working Paper 2011-22 Mei Dong, Janet Hua Jiang
We study price posting with undirected search in a search-theoretic monetary model with divisible money and divisible goods. Ex ante homogeneous buyers experience match specific preference shocks in bilateral trades. The shocks follow a continuous distribution and the realization of the shocks is private information.

Money and Costly Credit

Staff Working Paper 2011-7 Mei Dong
I study an economy in which money and credit coexist as means of payment and the settlement of credit requires money. The model extends recent developments in microfounded monetary theory to address the choice of payment methods and the effects of inflation. Whether a buyer uses money or credit depends on the fixed cost of credit and the inflation rate.

Inflation and Unemployment in Competitive Search Equilibrium

Staff Working Paper 2010-15 Mei Dong
Using a monetary search model, Rocheteau, Rupert and Wright (2007) show that the relationship between inflation and unemployment can be positive or negative depending on the primitives of the model. The key features are indivisible labor, nonseparable preferences and bargaining.
