Household surveys are often plagued by item non-response on economic variables of interest like income, savings or the amount of wealth. Manski (1989, 1994, 1995) shows how, in the presence of such non-response, bounds on conditional quantiles of the variable of interest can be derived, allowing...

This paper shows which statistical techniques can be used to validate simulation models, depending on which real-life data are available. Concerning this availability, three situations are distinguished (i) no data, (ii) only output data, and (iii) both input and output data. In case (i) - no...

We analyze the joint convergence of sequences of discounted stock prices and the Radon-Nicodym derivatives of the minimal martingale measure when interest rates are stochastic. Therefrom we deduce the convergence of option values in either complete or incomplete markets. We particularize the...

In this paper, we estimate a reliable fundamental value of the S&P index, standing for a long run target value in Error-Correcting Modelling of the dynamics of the subsequnet returns. The present Value Model suggests two fundamentals: the dividends and a discount rate factor, specified as a...

We study the effect of riskiness on optimal portfolio. As discussed by Levy (1992), the main drawback of the standard model witg ine decision variable and one risky asset developed over the last twenty-five years, following the contributions of Rothschild and Stiglitz (1970,1971) and Hadar and...
