Since its first inception in the debate on the relationship between environment and growth in 1992, the Environmental Kuznets Curve has been subject of continuous and intense scrutiny. The literature can be roughly divided in two historical phases. Initially, after the seminal contributions,...

This paper examines two possible sources of interaction between private and public capital in an endogenous growth model with productive public investment, which is used as an input both in the production of final output and in the production of new public capital. On the one hand ,public...

Accurate forecasts of incoming calls are crucial to optimal staffing decisions in call centers. This paper evaluates a wide range of models and forecast combination techniques by means of statistical and economic criteria. Relative to the previous literature, this paper is novel in several...

In this paper, we study some IFS Markov operators on set-valued measures (multimeasures). For this, we consider countable additivity with respect to the Minkowski sum of compact and convex sets and countable additivity with respect to (the Hausdorff closure of) unions of compact sets. After...

The standard electricity industry reform paradigm in several EU countries since the 1990s includes privatization, unbundling, liberalization. While the implementation and design of reforms widely differs across the EU, the European Commission insists on a rather unified approach, aiming at the...

In the past two decades privatisation and liberalisation of network industries providing services of general economic interest (SGEI), have been particularly significant in the European Union. Wide variations around a common policy trend can, however, be observed across countries and sectors. We...

This paper analyzes how population and product market competition may interact with each other in affecting the pace of productivity growth. We find that the impact of a change in population (size/growth) and in the degree of market concentration on economic growth varies depending on the...

In this paper we are interested in the direct and inverse problems for the following class of random fixed point equations $T(w,x(w))=x(w)$ where $T:\Omega\times X\to X$ is a given operator, $\Omega$ is a probability space and $X$ is a complete metric space. The inverse problem is solved by...

The present paper provides an overview of the main types of surveys carried out for customer satisfaction analyses. In order to carry out these surveys it is possible to plan a census or select a sample. The higher the accuracy of the survey, the more reliable the results of the analysis. For...

This paper studies the effects of product market integration on wage-bargaining institutions. It first shows evidence of a negative correlation between the level of wage bargaining and proxy measures of integration, such as the degree of openness and import penetration, for a macro-panel of 17...
