We take to the data an RBC model with two salient features. First, we allow government consumption to directly affect the marginal utility of consumption. Second, we allow public capital to affect the productivity of private factors. On the one hand, private and government consumption are...

This article is focused on fiscal stimulus and exit strategies in a small euro area economy. The analysis is based on a New-Keynesian general equilibrium model with non-Ricardian features introduced in Almeida, Castro and Félix (2010). We define a benchmark fiscal stimulus and, conditional on...

Using PESSOA, a medium-scale DSGE model for a small euro-area economy, we evaluate how scal adjustments impact short- and medium-term debt dynamics and output for alternative policy options, and budgetary and economic conditions. Fiscal djustments may increase the public debt-to-GDP ratio in the...

This paper develops a new measure of quarterly discretionary tax shocks for Portugal that result from changes in legislation, following the narrative approach. It covers the years from 1996 to 2012 and was based on a comprehensive analysis of tax policy measures taken in the course of this...

We investigate the reaction of output to government spending shocks at the zero lower bound (ZLB) on the nominal interest rate when government and private consumption are non-separable in preferences. In particular, substitutability between private and government consumption significantly...

This article presents a detailed description of PESSOA - Portuguese Economy Structural Small Open Analytical model. PESSOA is a dynamic general equilibrium model that can be applied to any small economy integrated in a monetary union. The main theoretical reference behind its structure is...

In this paper, we analyze the implications of price setting restrictions for the conduct of cyclical fiscal and monetary policy. We consider an environment with monopolistic competitive firms, a shopping time technology, prices set one period in advance, and government expenditures that must be...

We study environments with sticky prices, wages or portfolios where it is feasible and optimal to use monetary policy to replicate the allocation under full flexibility. In these environments the optimal policy does not depend on the scope of the frictions. In this sense, the strength of the...

What instruments of monetary policy must be used in order to implement a unique equilibrium? This paper revisits the issues addressed by Sargent and Wallace (1975) on the multiplicity of equilibria when policy isconducted with interest rate rules. We show that the appropriate interestrate...

We consider standard cash-in-advance monetary models and show that there are interest rate or money supply rules such that equilibria are unique. The existence of these single instrument rules depends on whether the economy has an infinite horizon or an arbitrarily large but finite horizon.
