We study the effects of optimized monetary policy in a semi-structural, estimated small open economy in situations where the policymaker has either complete or less than complete confidence in the model being free from misspecification errors. We use the robust control techniques developed by...

We consider optimal policy when private sector expectations are formed through adaptive learning. Earlier research has found that adaptive learning is consistent with empirical evidence on private sector expectations. In this paper, we consider the (admittedly) extreme case of sophisticated...

Czech Republic, Hungary and Poland will have to join the European and Monetary Union. Surprisingly, there is very little work on the welfare consequences of the loss of monetary policy flexibility for these countries. This paper fills this void by providing a framework to evaluate quantitatively...

We employ a new decision-theoretic approach to dealing with Knightian uncertainty based on Simon's bounded rationality. The basic tool of this approach is a quantitative answer to the question: For a specified policy, among a set of policies, how much can our assumptions regarding e.g. model and...

We evaluate the second order solution of a general equilibrium model for a small open economy in the line of the "new open economy macroeconomics". We use this framework to explain some recent regularities observed in economies in which central banks move from using a money aggregate as the...

Sudden and protracted oil-price increases are generally accompanied by economic contractions and high inflation. How should monetary policy react to oil-price shocks in order to minimize such adverse macroeconomic effects? We build a DSGE model characterized by two oil-importing countries and...

Centralized exchange has a worst-case size-complexity many orders of magnitude lower than decentralized monetary exchange for the same number of agents and goods. A more rapid approach to competitive equilibrium may therefore be possible through centralized exchange. An additional benefit of...

We examine optimal and other monetary policies in a linear-quadratic setup with relatively general forms of model uncertainty. The forms of uncertainty our framework encompasses include: simple i.i.d. model deviations; serially correlated model deviations; estimable regime-switching models; more...

n this paper we develop the Generalize Taylor Economy (GTE) in which there are many sectors with overlapping contracts of different lengths. We are able to show that even in economies with the same average contract length, monetary shocks will be more persistent when there are longer contracts....

We study monetary and fiscal policy games in a dynamic sticky priceeconomy where monetary policy sets nominal interest rates and fiscal policy provides public goods financed with distortionary labor taxes. We compare the Ramsey outcome to non-cooperative policy regimes where one or both...
