This paper proposes a model in which retail prices are sticky even though firms can always change their prices at zero cost. Instead of imposing a "menu cost", we assume that more precise decisions are more costly. In equilibrium, firms optimally make some errors in price-setting, thus...

A dynamic, stochastic optimizing macromodel with predetermined money wages and labour market monopoly power is used to examine the effect on current macroeconomic variables of a temporary increase in variability of the future money supply. As a benchmark, we show that under perfect wage-price...

A dynamic stochastic model of a small open monetary economy with infinitely-lived optimizing households is constructed. There are temporary nominal rigidities in the labour market, while in goods and asset markets prices are flexible. Optimizing behaviour in the foreign country is also modelled....

A vast empirical literature has documented delayed and persistent effects of monetary policy shocks on output. We show that this finding results from the aggregation of output impulse responses that differ sharply depending on the timing of the shock: When the monetary policy shock takes place...

It has been widely argued that inflation persistence since WWII has been widespread and durable and that it can only be accounted for by models with a high degree of nominal rigidity. We examine UK post-war data where after confirming previous studies’ findings of varying persistence due to...

We look for a theoretical justification of nominal wage contracts in household diversification of risk. We assume it is more costly for households than for firms to use financial markets for this purpose. In a calibrated general equilibrium model we find from stochastic simulation that if both...

This paper studies optimal monetary policy from the timeless perspective in a general model of state-dependent pricing. Firms are modeled as monopolistic competitors subject to idiosyncratic menu cost shocks. We find that, under certain conditions, a policy of zero inflation is optimal both in...

We present a new partial equilibrium theory of price adjustment, based on consumer loss aversion. In line with prospect theory, the consumers' perceived utility losses from price increases are weighted more heavily than the perceived utility gains from price decreases of equal magnitude. Price...

How do frictions in price setting influence monetary non-neutrality? We revisit this classic question in a quantitative menu cost model with multi-product firms that face idiosyncratic shocks with unsynchronized stochastic volatility. The model matches the unconditional distribution of price...

This article is related to the large recent literature on Phillips curves in sticky- price equilibrium models. It differs in allowing for the degree of price stickiness to be determined endogenously. A closed-form solution for short-term inflation is derived from the dynamic stochastic general...
