We analyze optimal policy in a simple small open economy model with price setting frictions. In particular, we study the optimal response of the nominal exchange rate following a terms of trade shock. We depart from the New Keynesian literature in that we explicitly model interna-tionally traded...

In contrast to the past, many emerging countries faced the global financial crisis of 2008-2009 with more solid financial positions and the required credibility and capacity to conduct countercyclical policies. This allowed them to better cope with the global downturn and thus behave more...

In this article, we analyze the implications of price-setting restrictions for the conduct of cyclical fiscal and monetary policy. We consider standard monetary economies that differ in the price-setting restrictions imposed on the firms. We show that, independently of the degree or type of...

We study economies where government currency and electronic money, drawn from interest bearing deposits in private financial intermediary institutions, are full substitutes. We analyze the impact of competition on policy outcomes under different assumptions regarding: the objectives of the...

The Phillips curve refers to a negative (or inverse) relationship between unemployment and inflation in an economy—when unemployment is high, inflation tends to be low, and vice versa. This inflation-unemployment link has been observed in many countries during many times, most famously by...

We show that regulatory changes that occurred in the banking sector in the early eighties, which considerably weakened Regulation Q, can explain the apparent instability of money demand during the same period. We evaluate the effects of the regulatory changes using a model that goes beyond...

Consumption-based asset pricing models with time-separable preferences can generate realistic amounts of stock price volatility if one allows for small deviations from rational expectations. We consider rational investors who entertain subjective prior beliefs about price behavior that are not...

Most economic models used by central banks prior to the recent financial crisis omitted two fundamental elements: financial markets and liquidity measures. Those models therefore failed to foresee the crisis or understand the policy reaction that followed. In contrast to more orthodox models, we...

This paper makes two straightforward points that we argue are central to understanding the literature and debate surrounding the stability of the Phillips curve. First, the endogeneity of monetary policy implies that aggregate data are largely uninformative as to the existence of a stable...

We study a model with heterogeneous producers that face collateral and cash-in-advance constraints. These two frictions give rise to a nontrivial financial market in a monetary economy. A tightening of the collateral constraint results in a recession generated by a credit crunch. The model can...
