This paper developes a small open economy model in which domestic resource shocks play a vital role in driving the dynamics of the major macroeconomic aggregates. Households rent capital and labour to rms and have access to an international bond market. The model is calibrated to recent Icelandic data and simulated under two alternative exchange rate regimes: oating rates, and monetary union me...

This paper evaluates quantitatively the effect of real money balances in a New Keynesian framework. Money in our model facilitates transactions and is introduced through a transactions cost technology. This technology acts like a distortionary consumption tax which varies endogenously with the nominal interest rate. In this setup the resultant Phillips curve becomes a function of the nominal in...

We examine optimal and other monetary policies in a linear-quadratic setup with a relatively general form of model uncertainty, so-called Markov jump-linear-quadratic systems extended to include forward-looking variables and unobservable “modes.” The form of model uncertainty our framework encompasses includes: simple i.i.d. model deviations; serially correlated model deviations; estimable regi...

Previous literature on statistical properties of interbank loans has reported various power-laws, particularly for the degree distribution (i.e. the distribution of credit links between institutions). In this paper, we revisit data for the Italian interbank network based on overnight loans recorded on the e-MID trading platform during the period 1999-2010 using both daily and quarterly aggregat...

This paper explores a reason why retailers pay such large merchant fees to credit card issuers. Credit cards as media of exchange are introduced to a New Monetarist model in which exchange occurs in alternating centralized and decentralized markets. Sellers who exert high (low) effort produce a good with a high (low) probability of being high quality. The quality of the good is revealed only af...

How much should we expect monetary integration to reduce differences among participating economies? Using data for the 50 U.S. states over 1929–1999, the paper finds that large differences across states persist in both business-cycle variability and correlations of state income with the U.S. as a whole. It is also shown that about a third of a state’s business-cycle volatility is explained by i...

This paper adopts a New Keynesian approach to analyze the relationship between nominal interest rates and prices. In this new framework, both a positive relation between interest rates and price levels (i.e., a positive Gibson effect) and a negative relation between interest rates and subsequent price changes (i.e., a negative Fama-Fisher effect) arise when money is supplied inelastically and p...

The purpose of the paper is to survey and discuss in‡ation targeting in the context of monetary policy rules. The paper provides a general conceptual discussion of monetary policy rules, attempts to clarify the essential characteristics of in‡ation targeting, compares in‡ation targeting to other monetary policy rules, and draws some conclusions for the monetary policy of the European System of ...

We examine optimal and other monetary policies in a linear-quadratic setup with a relatively general form of model uncertainty, so-called Markov jump-linear-quadratic systems extended to include forward-looking variables and unobservable “modes.” The form of model uncertainty our framework encompasses includes: simple i.i.d. model deviations; serially correlated model deviations; estimable regi...

We study what features an economic environment might possess, such that it would be Pareto efficient for the exchange of goods in that environment to be conducted on spot markets where those goods trade for money. We prove a conjecture that is essentially due to Bewley [1980, 1983]. The gist is that monetary spot trading is nearly efficient ex ante in an environment where very patient agents ca...
