This paper explores the capacity for environmental fiscal reform to reduce CO2 emissions, stimulate economic performance, and promote fiscal sustainability. Simulation results suggest that reforms based on CO2 taxation stimulate GDP when tax revenues are used to promote private or public...

This paper examines the economic and budgetary impacts of fuel prices using a dynamic general equilibrium model of the Portuguese economy which highlights the mechanisms of endogenous growth and includes a detailed modeling of the public sector. The fuel price scenarios are based on forecasts by...

The objective of this paper is to identify the effects of railroad infrastructure investment on aggregate and regional economic performance in Portugal. At the aggregate level, we show that railroad investment crowds in private investment and employment and have strong effects on output. At the...

This paper presents an inter-temporal model of individual savings behavior with intra-marriage financial distributions and uncertainty about marriage and divorce. Spouses paying these distributions experience diseconomies of marriage; the spouses who receive them benefit from economies of...

We use a dynamic general equilibrium model to quantify the likely long-term impact of a fiscal devaluation on the Portuguese economy. In a context of exogenous growth, and imposing an unchanged budget deficit to GDP ratio in the year the policy is enacted, we find that a tax swap worth 1 percent...

We estimate the long-term impact of changes in social security and social protection spending on economic performance in the USA. We estimate a VAR model relating GDP, unemployment rates, saving rates, and social spending. Our results suggest that social spending has significant distortionary...

In this paper we describe the model structure, data, and implementation procedures for the Dynamic General Equilibrium model of the Portuguese Economy, DGEP for short. Previous versions of this model have been used to evaluate the impact of tax policy and social security reform in Portugal. More...

We estimate the long-term impact of social security and social protection spending in a set of twelve EU countries. We estimate country-specific VARs relating GDP, unemployment, savings, and social spending. We find that social spending has a negative effect in most countries while the effects...

Computable general equilibrium (CGE) and bottom-up models each have unique strengths and weakness in evaluating energy and climate policies. This paper describes the development of an integrated technological, economic modelling platform (HYBTEP), built through the soft-link between the bottomup...

This document presents a description and discussion of the implementation of a soft link between a CGE Model for Portugal and the TIMES_PT energy systems model. It outlines in great detail four alterations to the model structure and GAMS code to accommodate the transfer of information from the...
