In a payment card association such as Visa, each time a consumer pays by card, the bank of the merchant (acquirer) pays an interchange fee (IF) to the bank of the cardholder (issuer) to carry out the transaction. This paper studies the determinants of socially and privately optimal IFs in a card...

Structural vector-autoregressive models are potentially very useful tools for guiding both macro- and microeconomic policy. In this paper, we present a recently developed method for exploiting non-Gaussianity in the data for estimating such models, with the aim of capturing the causal structure...

Tiny changes in the American monetary policy can have dramatic effects on the rest of the world because of dollar's double role of national and international currency. This is the Triffin dilemma. The paper shows how it works through three examples: price of commodities, dollarization, and the...

We study how the optimal degree of conservatism relates to decision-making procedures in a Monetary Policy Committee (MPC). In our framework, central bank conservatism is required to attenuate the volatility of monetary decisions generated by the presence of uncertainty about the committee...

In many markets, consumers need to sign advance contracts with upfront fees and usage-based payments. Yet they may value consumptions inconsistently over time. They tend to overconsume temptation goods (e.g., credit cards), but underconsume aversion goods (e.g., gym visits), relative to initial...

This paper proposes a tractable New Keynesian (NK) economy with endogenous adjustment in product quality that nests the canonical framework. Endogenous quality choice reduces the slope of the traditional NK Phillips curve and ampliffes the economy's response to productivity shocks. This leads to...
