I employ a large set of scanner price data collected in retail stores and document that (i) although the average magnitude of price changes is large, a substantial number of price changes are small in absolute value; (ii) the distribution of non-zero price changes has fat tails; and (iii) stores...

If firm pricing is state, rather than time-dependent, firms are more likely to change prices whenever aggregate and idiosyncratic shocks reinforce each other and trigger desired price changes in the same direction. The distribution of idiosyncratic shocks across adjusting firms therefore varies...

Here I describe the dynamical model of a “pure” inflationary process and give a model-based definition of the inflation.

Modern monetary policy analysis is built around the concept of an interest rate rule that responds to both inflation and output. This paper evaluates the quantitative implications of having a policy rule target different definitions of the output gap in a New Keynesian model with endogenous...

This paper studies the co-movements of unemployment and labor productivity growth for the U.S. economy. Measures of co-movements in the frequency domain indicate that co-movements between variables differ strongly according to the frequency. First, long-term and business cycle co-movements are...

Presented here is the mathematical model with one commodity describing the dynamics of the inflationary process. This model is also applied to research how the hypothesis of rational expectations could affect the commodity's demand and production after increasing the amount of money on the market.

(This abstract and the paper are in Turkish.) Ekonomik krizler; herhangi bir mal, hizmet, uretim faktoru veya doviz piyasasindaki fiyat ve/veya miktarlarda, kabul edilebilir bir degisme sinirinin otesinde gerceklesen siddetli dalgalanmalar olarak tanimlanabilir. Soz konusu krizlerin ortaya...

This paper considers a sticky price model with a cash-in-advance constraint where agents forecast inflation rates with the help of econometric models. Agents use least squares learning to estimate two competing models of which one is consistent with rational expectations once learning is...

This work is focused on identifying a circular pull production control system (PPCS) and make emphasis on the presence of a stability attribute. It is an introductory paper to an extended study of macroeconomic financial stability in a physically open but systemic closed system. Previous work...

The New-Keynesian Phillips curve plays a central role in modern macroeconomic theory. A vast empirical literature has estimated this structural relationship over various postwar full-samples. While it is well know that in a New-Keynesian model a weak central bank response to inflation generates...
