This paper argues that inequality can be both good and bad for growth, depending on what inequality and whose growth. Unequal societies may be holding back one segment of the population while helping another. Similarly, high levels of income inequality may be due to a variety of different...

Abstract We use a simple growth model with public capital to examine the evolution of the US macroeconomy and to discuss the implications of the public infrastructure decline for the productivity slowdown over the last four decades. The main difference of the model to other papers in the related...

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...

Distinguishing between traffic generated exclusively from the expansion of the road network (induced demand) and that resulting from other demand factors is of crucial importance to properly designed transport policies. This paper analyzes and quantifies the induced demand for road transport for...

In a Barro-type economy with exogenous consumption aspirations, raising income taxes favors growth even in the presence of lump-sum taxes. Such a policy is compatible with the behavior of private consumption, income taxes and growth rates observed in actual economies.

The main purpose of this paper is to assess efficiency of the Brazilian electricity generation mix proposed in the 2020 Decennial Plan for Energy Expansion (DPEE 2020). It evaluates estimated costs, risks and CO2 emissions following the mean–variance portfolio theory. The efficiency frontier...

Following the goal of improving on-road fuel efficiency, the Spanish Government engaged in an active policy called the dieselization between 1998 and 2006, which was intended primarily for light duty vehicle (mostly passenger cars and SUV’s). However, the effect of the dieselization on...
