In this paper we develop a multiple equilibria one-sector R&D-based growth model, in which the key aspects are the assumption of complementarities between capital goods in the production function and the assumption of costly investment in capital. This second assumption is new to the R&D-based...

We propose a theoretical growth model with which to frame analytically the Quadruple Helix Innovation Theory (QHIT). The aim is to emphasise the investment in innovation transmission mechanisms in terms of economic growth and productivity gains, in one-high-technology sector, by stressing the...

We examine the behaviour of the skill premium in a two-country general equilibrium growth model assuming (i) technological-knowledge diffusion; (ii) internal costly investment in both physical capital and R&D; and (iii) complementarities between intermediate goods in production. We find that...

This paper builds on the ongoing discussion on regulation and marketisation of higher education. It aims at investigating the higher education market (des)equilibrium. Teixeira, Rosa and Amaral (2004) have analysed the presence/absence of market mechanisms in the Portuguese higher education...

This paper investigates the link between fiscal policy shocks and movements in asset markets using a Fully Simultaneous System approach in a Bayesian framework. Building on the works of Blanchard and Perotti (2002), Leeper and Zha (2003), and Sims and Zha (1999, 2006), the empirical evidence for...

A large body of empirical literature has suggested that oil price shocks have an important effect on economic activity. But in most of the literature the analysis is exclusively done in the time domain. However, interesting relations exist at different frequencies. We use (cross) wavelet...

Although the literature on the political economy of public finance is already quite extensive, most articles analyse the behaviour of central governments. Furthermore, studies about the Portuguese economy are scarce. The present article contributes for a better understanding of these phenomena...

Economic agents simultaneously operate at different horizons. Many economic processes are the result of the actions of several agents with different term objectives. Therefore, economic time-series is a combination of components operating on different frequencies. Several questions about the...

This paper offers additional insights on the interactions between economics and politics in Portugal. We use an unexplored data set consisting of monthly polls on vote intentions for the main political parties in Portugal, since 1986. Results indicate that: (1) socialist governments had less...

In Portugal, as in most other European Union (EU) countries, the challenge of Economic and Monetary Union (EMU) has worked as a mechanism for economic stabilisation. However, the political consensus on the participation in EMU did not develop with respect to the need for implementing structural...
