In this paper we consider several time-varying volatility and/or heavy-tailed models to explain the dynamics of return time series and to fit the volatility smile for exchange-traded options where the underlying is the main �Borsa Italiana� stock index. Given observed prices for the...

Most of the important models in finance rest on the assumption that randomness is explained through a normal random variable because, in general, the use of alternative models is obstructed by the difficulty of calibrating and simulating them. In this paper, we empirically study models for...

The European Emissions Trading Scheme (ETS) is a cap and trade system to curb CO2 emissions. It has caused both direct costs (CO2 allowances) and indirect costs (higher electricity prices) to energy-intensive industries. Moreover, as there is no global CO2 agreement, the ETS could distort the...

The paper investigates the organization of the Italian water sector in the light of the reforms of public utilities. The aim is to examine the degree of implementation of the water sector reform (the so-called Galli Law of 1994) and assess the performance of operators through a study of their...

The real estate sector is of particular interest from a central bank's perspective; due to its size, it directly and indirectly affects economic developments, financial stability and the monetary policy stance.

This paper studies the determinants of Chinese households� saving. Domestic saving in China is the highest in the world in terms of GDP and it is mirrored in a large and persistent current account surplus. First, we show that notwithstanding the rising contribution of government and firms...

In this paper I estimate the impact of changes in real and financial wealth � proxied by house and stock market prices � on private consumption for a panel of sixteen emerging economies in Asia and Central and Eastern Europe. Using recent econometric techniques for heterogeneous...

The relationship between the demographic structure and the saving rate of a society is the reflection of the aggregation of the behaviour of heterogeneous households, differing from one another in the type of living arrangements and in the characteristics of their members. In order to contribute...

This paper analyzes the determinants of Italian households� participation in the debt market, considering both demand and supply effects and using the Bank of Italy�s Survey of Household Income and Wealth. The probability of debt is positively influenced by age (until 35 years), which...

This paper proposes a test for the cost-based explanation of non-participation, by estimating a lower bound to the forgone gains of incomplete portfolios; these are in turn a lower bound to the costs that could rationalize non-participation in financial markets: high bounds would imply...
