The paper analyzes asset pricing implications of commonly used performance fees linking the compensation of fund managers to the return of the managed portfolio relative to that of a benchmark portfolio. Symmetric(fulcrum) performance fees distort the allocation of managed portfolios in a way...

Value at Risk (VaR) has emerged in recent years as a standard tool to measure and control the risk of trading portfolios.Yet,existing theoretical analyses of the optimal behavior of a trader subject to VaR limits have produced a negative view of VaR as a risk-control tool. In particular,VaR...

This paper constructs a representative agent supporting the equilibrium allocation in ¡°event-tree¡± economies with time-additive preferences and possibly incomplete securities markets. If the equilibrium allocation is Pareto optimal, this construction gives the usual linear welfare...

This paper presents a general method for valuing fixed rate bonds and options written on them. In the first part, of a theoretical nature, we present valuation formulae, derived within the framework of the Cox, Ingersoll and Ross (CIR) model, both for bonds and for European options written on...

This paper, which follows up the analyses of an earlier study published in December 1988, starts by updating the description of the regulatory framework for Italian stock options (premium contracts), with reference both to the regulations issued by the Consob (the Italian SEC) and the changes in...

This paper tests the Cox, Ingersoll and Ross model using the prices of Italian Treasury bonds in the secondary market. The model is estimated daily for the period 30 December 1983 to 13 March 1989. The resulting term structures of interest rates are compared with those obtained using...

The Italian Treasury's puttable bonds (Certificati del Tesoro con opzione di rimborso anticipato - CTOs) are the first example in Italy of retractable/extendible bonds, which have been used on the Canadian market for some time and recently been adopted on the Euromarket. In this paper the...

This paper examines optimal consumption and investment choices and the cost of hedging contingent claims in the presence of margin requirements or, more generally, of nonlinear wealth dynamics and constraints on the portfolio policies. Existence of optimal policies is established using...
