We analyze the effects of market microstructure noise on the Fourier estimator of multivariate volatilities. We prove that the estimator is consistent in the case of asynchronous data and robust in the presence of microstructure noise. This result is obtained through an analytical computation of...

Any economic activity calls for the exercise of moral judgement. There are some economic activities that actively promote collective benefit as a primary or secondary aim, and there are others that aim to increase the value of a firm. Investment decisions always have collective impact, but...

The paper argues that the shape of the long-run size distribution of business firms is basically determined by the availability of organisational capabilities, and that its changes over time (the "direction" of change) depend on the way in which (exogenous) "environmental" conditions affect...

This paper investigates the effect of real assets as collateral on the economy. I show how credit rationing is mitigated by the exsistence of bad firms whether it is linked to the value of distressed assets. Indeed, when loans are collateralized and firms are credit constrained, the amount...

The Tobacco CMO (Common Market Organization) is involved in a intense debate between the European tobacco industry and those who are against to a crop whose transformed product is dangerous to the health. European institutions have shown a strong interest in this complex issue introducing two...

We show that the use of pooled and panel data in estimating convergence across countries (or other territorial areas) may involve some pitfalls since this type of data cannot properly distinguish between actual convergence and the possibility of decreasing growth rates over time within each...

In this work, we analyse different numerical methods for the approximation of the Black-Scholes equation for the European option pricing. Such an equation presents two main sources of difficulties with regards to its discretization…We explore the effects of both characteristics in terms of...
