We ask why, in many circumstances and many environments, decision-makers choose to act on a time-regular basis (e.g. adjust every six weeks) or on a stateregular basis (e.g. set prices ending in a 9), even though such an approach appears suboptimal. The paper attributes regular behaviour to...

The study on price stickiness examined nominal rigidities in the euro area and their importance for the functioning of markets. The study examined nominal rigidities in the euro area and their importance for the functioning of markets. It analysed the price setting behaviour of firms at the...

The paper studies the effect of inflation on price behaviour using price data from Canadian daily newspapers. We test the Sheshinski and Weiss (1977) monopoly price adjustment model on a sample of monopolistic as well as oligopolistic newspapers, in contrast to earlier studies that used data...

We analyze the effect of inflation on the average output of monopolistic firms facing a small fixed cost of changing nominal prices. Using Taylor expansions, we derive a general closed-form solution for the slope of the long-run Phillips curve. This very simple, unifying formula allows us to...

Discussion of: Lumpy Price Adjustments: A Microeconometric Analysis by Emmanuel Dhyne, Catherine Fuss, Hashem Pesaran and Patrick Sevestre, National Bank of Belgium International Conference on \"Price and Wage Rigidities in an Open Economy\", Brussels, October 12, 2006.

I analyse the optimal rate of inflation when prices are costly to change. As the costs of price adjustment are the main friction in the model, effects of inflation stem from the accounting role of money. Inflation increases relative price variability and reduces the average product of labour....

We analyze the behaviour of prices using a large disaggregated data set for Poland during transition from a planned to a market economy. The size of price changes and the frequency of adjustment both fall as the inflation rate declines. Price setters follow a mixture of state- and...
