Due to wealth effects, the price of a security may vary with the realization of an underlying risk factor even when the security's dividend is independent of that factor. This paper highlights a crucial component of these effects hitherto ignored by the literature: changes in wealth do not alter...

Currently, financial economics is unable to predict changes in asset prices with respect to changes in the underlying risk factors, even when an asset's dividend is independent of a given factor. This paper takes steps towards addressing this issue by highlighting a crucial component of wealth...

The purpose of this paper is to present an exercise where we identify optimal income tax rules according to various social welfare criteria, keeping fixed the total net tax revenue. Empirical applications of optimal taxation theory have typically adopted analytical expressions for the optimal...

We present JAS 2, a new Java platform which aims at providing a unique simulation tool for discrete-event simulations, including agent-based and dynamic microsimulation models. JAS 2 is not released as a self-contained stand-alone application for model development. With the aim to develop...

Forecasting based on random intercepts models requires imputation of the individual permanent effects to the simulated individuals. When these individuals enter the simulation with a history of past outcomes this involves sampling from conditional distributions, which might be unfeasible. I...

We provide a general characterization of diffusion processes, allowing to analyze both risk-sharing and contagion at the same time. We show that interdependencies are beneficial when the economic environment is favorable, and detrimental when the economic environment deteriorates. The risk of...

Most Oecd Countries are experiencing a rapid population ageing. Italy adds to this picture a very low labour market participation of the elders, so that most projections of the impact of ageing on the labour market are rather pessimistic. However, there are other long run modifications currently...

In a single-commodity, pure-exchange, representative-agent economy with many Lucas' trees whose dividends are geometric Brownian motions, I study the comparative statics of the prices of these assets with respect to the current Brownian realization. As is well-known, due to wealth effects, a...
