A new method of empirically computing the macroeconomic returns to public investment is proposed. Pereira's (2000) technique is modified, and a measure which accounts for both public and private investment costs is suggested. An empirical application to US data shows that differences between...

We review the main budgetary measures not accepted by the Portuguese Constitutional Court in the Budget Laws of 2012, 2013 and 2014. Considering the feedback effect of the fiscal impulse, the impact on the budget balance is -0.42% and of -0.34% of GDP respectively for 2013 and for 2014; in both...

The EU 2020 Climate and Energy Package, in force since June 2009, commits the European Union to reduce its overall greenhouse gas (GHG) emissions to at least 20% below their 1990 levels by 2020, pursuing the ambition to make Europe a low-carbon and energy-efficient economy over the next decade....

In a cross section of OECD countries, we replace the macroeconomic production function by a production possibility frontier, total factor productivity being the composite effect of efficiency scores and possibility frontier changes. We consider, for the periods 1970, 1980, 1990 and 2000 one...

This paper performs a long-run time series analysis of the behaviour of the income velocity of money in Portugal 1891-1998, and assesses the importance of both macroeconomic and institutional factors in shaping its path. We look for particularities of the Portuguese case in the international...

Using annual data from 17 developed economies, we evaluate the macroeconomic effects of public and private investment through a five-variable vector autoregression. From impulse response functions, we assess the extent of crowding-in or crowding-out of both components of investment. We also...

The impact of human and public capital on growth is a major issue in economic theory and in policy evaluation. Using a cointegrated VAR, we estimate a Cobb-Douglas production function for Portugal with public and human capital. Return rates are then computed with and without dynamic feedbacks....

Endogenous, ideas-led, growth theory and agent based modelling with neighbourhood effects literature are crossed. In an economic overlapping generations framework, it is shown how social interactions and neighbourhood effects are of vital importance in the endogenous determination of the long...
