The risks associated with current and prospective costs of different energy technologies are crucial in assessing the efficiency of the energy mix. However, energy policy typically relies on the evolution of average costs, neglecting the covariances in the costs of the different energy...

In this paper we analyze the role of changes in the fuel mix on emissions reduction and the diversification of risks associated to rising prices of energy. To this purpose we evaluate the average cost and the cost volatility of alternative fuel combinations in the road transport sector by means...

Modelling the accumulation rule evolving public investment is an issue of utmost interest among economists and politicians. The present paper extends the Barro (1990) model of productive government expenditure by considering a time-adapted rule for the public investment/output ratio. The rule...

Using family income from the Panel Study of Income Dynamics (PSID), we apply Quantile Regression to estimate the Intergenerational Income Elasticity (IGE) by percentiles in the U.S. from 1980 to 2010. For the whole period, the IGE shows a Ushape across the income distribution, with maximum...

While debt-financed productive public investment raises a country’s debt ratios in the short run, it can also generate higher growth, revenues, and exports, leading over time to lower debt ratios. This paper develops a framework to assess whether countries meet the conditions for realizing the...

Individual income is determined by free-will actions related to the level of effort exerted and by opportunities determined by aspects beyond the individual's control, such as family background, race, place of birth or health endowments. Taking human capital as the main engine of development, we...

In this paper we analyze the role of changes in the fuel mix on emissions reduction and the diversification of risks associated to rising prices of energy. To this purpose we evaluate the average cost and the cost volatility of alternative fuel combinations in the road transport sector by means...

Theoretical and empirical studies exploring the effects of income inequality upon growth reach a disappointing inconclusive result. This paper postulates that one reason for this ambiguity is that income inequality is actually a composite measure of inequality of opportunity and inequality of...

This paper studies the change in Energy Intensity (<i>EI</i>) of the main economic activities in the EU15 countries, which represents approximately 45% of their final energy consumption. The purpose is, first, to measure the different patterns between the countries by establishing differentiated...
