Segmentation is a core strategy in modern marketing, and age-specific segmentation based on the age of the consumers is very common in practice. Age-specific segmentation enables the change of the segments composition during time and can be studied only by means of dynamic advertising models....

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...

One of the most important drawbacks of the existing literature on convergence is that it largely ignores the effect of aggregate fluctuations on the evolution of income disparities. To the extent that regional income disparities follow a distinct cyclical pattern in the short-run, moving either...

Simple models of competition for the market with endogenous entry show that, contrary to the Arrow view, an endogenous entry threat in a market induces the average firm to invest less in R&D and the incumbent leader to invest more. We test these predictions based on a unique dataset and survey...

The analysis of synchronization among regional or national business cycles has recently been attracting a growing interest within the economic literature. Far less attention has instead been devoted to a closely related issue: given a certain level of synchronization, some economies might be...

The Federal Reserve System or the Fed is one of the most prestigious institutions in the world.Founded by the Federal Reserve Act in 1913, the Fed has the responsibility of setting the monetary policy of the U.S. The Fed's actions affect the money supply in the U.S. market which has a direct...

We investigate in this paper the skirmishes that the US dollar and the euro had from 2007 to 2011 and, in particular, the two distinct sharp falls that the single currency had in 2008 and 2010. We basically consider how impulses coming from domestic money markets impact on the USD/EUR exchange...
