This paper formulates a stylized New Keynesian model in which each individual firm can select the frequency of its price adjustments, and we demonstrate that the endogeneity of the contract structure has a dramatic impact on the magnitude of the aggregate effects of steady-state inflation. We start by analyzing the exact nonlinear properties of a benchmark economy with exogenous contract durati...

I characterize time consistent equilibrium in an economy with price rigidity and an optimizing monetary authority operating under discretion. Firms have the option to increase their frequency of price change, at a cost, in response to higher inflation. Previous studies, which assume a constant degree of price rigidity across inflation regimes, find two time consistent equilibria — one with low ...

This paper uses a structurally estimated macroeconometric model, denoted the MC model, to evaluate inflation targeting in the United States. Various interest rate rules are tried with differing weights on inflation and output, and various optimal control problems are solved using differing weights on inflation and output targets. Price-level targeting is also considered. The results show that 1...

The most important economic measures are monetary. They have many different names, are derived in different theories and employ different formulas; yet, they all attempt to do basically the same thing: to separate a change in nominal value into a ‘real part’ due to the changes in quantities and an inflation due to the changes in prices. Examples are: real national product and its components, th...

entral banks differ in their specific inflation objectives and conduct of policy. However, they typically confront the common problem of identifying which price changes are permanent and which are transitory. Because of the lagged effects of monetary policy, mistaking the nature of price changes can be extremely costly. For example, the failure to detect the onset of inflationary pressures may ...

The central banks of New Zealand, Canada, and the United Kingdom have recently decided to make price stability the overriding goal of monetary policy. Similar proposals in the United States have received a lukewarm reception. Although some opponents have argued that moderate inflation is beneficial, many concede its effect on economic welfare is detrimental.1 Instead, they argue that a price st...

Optimal Price Indices for Targeting Inflation under Incomplete Markets In models with complete markets, targeting core inflation enables monetary policy to maximize welfare by replicating the flexible price equilibrium. In this paper, we develop a twosector two-good closed economy new Keynesian model to study the optimal choice of price index in markets with financial frictions. Financial frict...

inflation has always been an economic problem and different solutions have been proposed to control it. although it is said that “higher output lowers inflation rate” but it is true when other factors are constant. this study searches the answer to the following question: “what is the effect of inflation rate and output in a case that inflation rate and output growth has a volatility trend?” to...
