Mark-up cyclical behaviour is relevant in determining the size of government spending multiplier on output. While theoretical literature priviliged the counteryclical hypothesis, empirical evidence is far from being conclusive. Based on seminal Rotemberg and Saloner (1986) contribution, we build...

We derive necessary and suffcient conditions for simple monetary policy rules that guarantee equilibrium determinacy in the New Keynesian monetary model. Our modeling framework is derived from a fully specified optimization model that is still amenable to analytical characterisation. The...

The lack of convergence of growth rates among the world economies is probably one of the most debated topics in the last few years in theoretical and empirical research. In this period we have observed a strong resurgence of the debate about long-run growth, starting from the initial...

In this paper I consider a General Equilibrium framework to evaluate the role and the importance of the interactions between Monetary and Fiscal policies in the sense outlined by Leeper (1991) and the Fiscal Theory of the Price Level, in the determination of nominal and real term structure. The...

In this paper I jointly derive the stochastic process of the price level, the inflation rate, thenominal and real term structures, as function of monetary, fiscal and technological parameters within a general equilibrium framework. The novelty of the present approach is given by the possibility...

I compare four basic monetary policy rules belonging to the interest-rate pegging rules class in two different analystical frameworks representing the way through which nominal rigidities are designed. A first model consider the Calvo-Woodford mechanism of price adjustment, as has become...

In this paper I search for an optimal configurations of parameters for variants of the Taylor rule by using an Accurate Second-Order Welfare based method within a fully microfounded Dynamic Stochastic model, with price rigidities, without capital accu- mulation. Money is inserted via a...

The operational performance of a set of simple monetary pol- icy rules à la Taylor in a model with capital accumulation and nominal and real rigidities is discussed with a special emphasis on the volatility of output, nominal rate and in.ation rate. Within an enriched modelling framework it is...

On-line content delivery and vertical alliances between conduit and content providers are nowadays crucial issues in digital markets. In this paper, we discuss and compare a push and a pull model for on-line content delivery in the case of non-zero marginal cost for network transits because of...

The present paper compares the performance in terms of second order accurate welfare of opportunistic non-linear Taylor rules and with respect to traditional linear Taylor rules. The macroeconomic model representing the benchmark for the analysis includes capital accumulation (with quadratic...
