In this paper we propose a new similarity index, which can be used to compare model-based clustering solutions. We define also an adjusted-for-chance version, although we advise that, whenever feasible, bootstrap replications should be preferred to chance-corrected similarity indices. We...

This study investigates whether fiscal policy is able to affect the trend of employment rate, triggering hysteresis independently from GDP behavior. I attempt to shed a light on this issue analyzing a Panel of 17 OECD countries, covering the period 1980-2009 with annual data. The effects of...

Benoît Mandelbrot, the father of Fractal Geometry, developed a multifractal model for describing price changes. Despite the commonly used models, such as the Brownian motion, the Mutifractal Model of Asset Return (MMAR) takes into account scale-consistency, long-range dependence and heavy...

This paper examines the association between lifetime income and old age mortality risk, referred to as the income–mortality gradient, in Italy during the 1980s and 1990s. We find that the shape of the income–mortality gradient is characterized by two discontinuities (knots) for males and one...

We analyze the evolution of the price of paintings in the XVII century Amsterdam art market to test a hypothesis of endogenous entry: higher probability should attract more entry of painters, which in turn should lead to artistic innovations and more intense competition. We build a price index...

We evaluate European financial options under continuous cumulative prospect theory. Within this framework, it is possible to model investors’ attitude toward risk, which may be one of the possible causes of mispricing. We focus on probability risk attitudes and consider alternative probability...

As a consequence of recent market conditions an increasing number of investors are realizing the importance of controlling tail risk to reduce drawdowns thus increasing possibilities of achieving long-term objectives. Recently, so called volatility control strategies and volatility target...

We study monopolistic competition under indirect additivity of preferences. This is dual to the Dixit-Stiglitz model, where direct additivity is assumed, with the CES case as the only common ground. Other examples include (perceived) demand functions that are exponential or linear. Our...

We provide a unified approach to imperfect (monopolistic, Bertrand and Cournot) competition equilibria with demand functions derived from symmetric preferences over a large but finite number of goods. The equilibrium markups depend on the Morishima Elasticity of Substitution/Complementarity...

Electric vehicles are usually perceived by policy makers and the general public as an attractive means to reduce greenhouse gas emissions. In this paper we provide a rigorous assessment of the emissions resulting from the diffusion of electric vehicles. We make use of EMOB, a comprehensive model...
