Higher-order robustness

The higher–order robustness for M–estimators is introduced and defined. The conditions needed to ensure higher stability of the asymptotic bias are provided by refining the Von Mises bias expansion. Admissible M–estimators featuring second–order robustness are thus introduced. Then, a saddle-point argument is applied in order to approximate the finite sample distribution of second–...

Options pricing with realized volatility

We develop a discrete-time stochastic volatility option pricing model, which exploits the information contained in high-frequency data. The Realized Volatility (RV) is used as a proxy of the unobservable log-returns volatility. We model its dynamics by a simple but effective (pseudo) long memory process, the Heterogeneous Auto-Regressive Gamma with Leverage (HARGL) process. Both the...

A fully parametric approach to minimum power-divergence estimation

We approach parameter estimation based on power-divergence using Havrda-Charvat generalized entropy. Unlike other robust estimators relying on divergence measures, the procedure is fully parametric and avoids complications related to bandwidth selection. Hence, it allows for the treatment of multivariate distributions. The parameter estimator is indexed by a single constant q,...

Some Thoughts about Referendums, Representative Democracy and Separation of Powers

Referendums have experienced some sort of a comeback. Citizen involvement in political decisions is seen increasingly as a healthy add-on in democratic polities. While earlier writers on democratic theory often saw a danger in increased participation of citizens, more recently several authors suggest that this participation should be fostered. I argue in this paper that both sides in...

Mergers and Acquisitions Comparative Economic Analysis of Laws: France vs. USA

From the economic point of view, common law is more efficient than civil law. Is this recent statement published in an economic report valid for mergers and acquisitions (M&A)? The main objective of this paper is to compare the legal performance of M&A in France and in the United States. The purpose is to quantify the impact of both legal systems on the long-term performance...

The impact of existing states on the building of kant's political philosophy: the case of the American polity

In this paper I ask the following question: of all the historical or the existing types of political regimes, which one would have had Kant's preference, which one would have counted for him as a model ? I guess he would have answered that it was the American polity which inspired him more than any other in history past and present. In the present contribution I'll try to...
