Market is in many respects distinct from barter. This distinction needs to be emphasized, because the conventional theory treats market and barter erroneously as the same. Barter is essentially bilateral in nature. It requires the reciprocity of supply and demand. The supplier has to demand the good that the demander of his goods offers and vice versa. Further, when both—the supplier and the de...

there are various causes for inflation in macroeconomics. one of the important channels of experiencing inflation is through the international economy caused by external shocks. in this context, the impact of exchange rate volatilities on domestic prices known as exchange rate pass-through (erpt) plays a vital role. the present paper deals with the impact of exchange rate pass-through on inflat...

Using Japanese scanner data of transaction prices and sales for more than 1,600 commodity groups from 1988 to 2008, we find a statistically significant negative correlation between the frequency of price changes and the degree of market concentration. We also find that structural factors of a distribution channel are significantly correlated with rigidity in retail prices. Decomposing the frequ...

The purpose of this paper is study the effect of monetary policy on asset prices. We study the properties of a monetary model in which a real asset is valued for its rate of return and for its liquidity. We show that money is essential if and only if real assets are scarce, in the precise sense that their supply is not sufficient to satisfy the demand for liquidity. Our model generates a clear ...

This paper has two related goals: (i) construct a model where money and credit coexist; (ii) pursue in this setting a theory of endogenous sticky prices that can be taken to the data. Search frictions generate price dispersion, and lead to monetary equilibria where profit-maximizing sellers set nominal prices they sometimes keep fixed when aggregate conditions change. Buyers can use cash or cre...

It is a well documented empirical fact that …rm level investment is lumpy rather than smooth. In the present paper we …nd that the aggregate consequences of lumpy investment in general equilibrium are quantitatively important. Earlier results stressing the irrelevance of lumpy investment in general equilibrium are therefore an artefact of assuming perfect competition combined with fully ‡exible...

abstract export of nonoil goods in economic activities is so important and its effect on economic and comparative growth is undeniable. so, emphasize on agricultural sector and development of export in this sector prepares good conditions, for iran, to be present at international markets relying its advantages. the study tries to recognize necessary policies to enhance agricultural export poten...

When the zero lower bound on nominal interest rates binds, monetary policy cannot provide appropriate stimulus. We show that in the standard New Keynesian model, tax policy can deliver such stimulus at no cost and in a time-consistent manner. There is no need to use ine¢ cient policies such as wasteful public spending or future commitments to in‡ate. We conclude that in the New Keynesian model,...

This paper studies U.S. in‡ation adjustment speed to aggregate technology shocks and to monetary policy shocks in a medium size Bayesian VAR model. According to the model estimated on the 1959-2007 sample, in‡ation adjusts much faster to aggregate technology shocks than to monetary policy shocks. These results are robust to di¤erent identi…cation assumptions and measures of aggregate prices. Ho...

In the past decade changes in oil prices have played a significant role in shaping inflation dynamics in the US and in the euro area, largely through their direct effect on liquid fuels prices. This has revived the controversy on whether fuels consumer prices respond more promptly to positive than to negative oil price shocks. This paper provides fresh evidence on the link between liquid fuels ...
