In this paper we present an application for a multiobjective optimization problem. The objective functions of the primal problem are the risk and the expected pain associated to a portfolio vector. Then, we present a Lagrangian dual problem for it. In order to formulate this problem, we...

The present paper considers an Italian dataset with an annual frequency from 1861 to 2000. It implements Granger non-causality tests between energy consumption and output contrasting methods allowing for structural change with those imposing parameter stability throughout the sample. Though some...

To model intraday stock price movements we propose a class of marked doubly stochastic Poisson processes, whose intensity process can be interpreted in terms of the effect of information release on market activity. Assuming a partial information setting in which market agents are restricted to...

In a multivariate setting, we document that renewable energy generation has a positive impact on economic growth at the regional level in Italy. We do so by adopting panel data unit-root and cointegration tests as well as Granger non-causality tests relying on the system GMM estimator. Our...

This paper evaluates the effect of two policy changes on the efficiency of Italian regional governments in the provision of health care services: first a change in the electoral system; second a process of fiscal decentralisation. The electoral system was changed in 1995 and replaced a pure...

Within the framework of dynamic panel data models with mean stationarity, one additional moment condition may remarkably increase the efficiency of the system GMM estimator. This additional condition is essentially a condition of “homoskesdasticity” of the individual effects; it is...

We investigate the link between inflation, growth and unemployment nesting a model of fair wages into one of endogenous growth of learning by doing and assuming that firms protect wages' purchasing power against inflation in exchange of worker's effort. Unemployment decreases with higher...

Consider the most simple problem in microeconomics, a maximization problem with an additive separable utility function over bundles of two goods which provide equal sat- isfaction to an agent. Although simple, this framework allows for a very wide range of applications, from the Arrow-Debreu...

The Great Recession seems to be a natural experiment for macroeconomics showing the inadequacy of the predominant theoretical framework — the New Neoclassical Synthesis — grounded on the DSGE model. In this paper, we present a critical discussion of the theoretical, empirical and...

We test the hypotheses of industry return rates either gravitating around or converging towards a common value in Taiwan and New Zealand. We adopt various econometric approaches. The results are then nested in a meta-analytic framework together with those of the past literature. Various kinds of...
