This paper extends a recent martingale representation result of [N-S] for a Levy process to filtrations generated by a rather large class of semimartingales. As in [N-S], we assume the underlying processes have moments of all orders, but here we allow angle brackets to be stochastic. Following...

This paper presents quite recent (2003) review of the Portuguese pension system with a particular focus on the public pension provision organised by the state. First part briefly explains the origins of the system. Chapter two focuses on the structure of the pension system, with a general...

The purpose of this article is to propose a typology of the economic behaviour of French industrial companies in 1993 based on a sample of more than 7,000 companies participating in the Balance Sheet Data Centre of the Banque de France. The objective is therefore to explain how productivity and...

The theory of asset pricing, which takes its roots in the Arrow-Debreu model (Theory of value [1959, chap. 7]), the Black and Sholes formula (1973) and Cox and Ross (1976 a and b), has been formalized in a general framework by Harrison and Kreps (1979), Harrison and Pliska (1979) and Kreps...

Risk-neutral valuation is used widely in derivatives pricing. It is shown in this paper, however, that the naïve approach of simply setting the growth rate of the underlying security to risk-free interest rate, which happens to work for a geometric Brownian motion (GBM) process, fails to work...

This paper develops a model in which managers can signal their firms' true values by using either a dividend or a stock repurchase or both. The authors explain a number of sylized facts about these cash- disbursement mechanisms, particularly those concerning the relative magnitudes of stock...

The RFIs operating in Maharashtra have not only shown slower growth in their loan advances and other operational indicators during the period between 1991 and 2000 but also poor performance thereafter. The credit cooperatives in particular have shown significantly high NPAs in Maharashtra. In...

This study examines the forecastability of ASEAN-5 stock market returns using linear and non-linear time series models. Time series models with GARCH errors are also considered. Based on formal econometrics tests, this study shows that the behaviour of these returns do not follow random walk...

This paper tests the hypothesis that irrational market misvaluation affects firms' takeover behavior. We employ two contemporaneous proxies for market misvaluation, pre-takeover book/price ratios and pre-takeover ratios of residual income model value to price. Misvaluation of bidders and targets...

A constraint that consumption cannot fall over time (or can fall only at a limited rate) can arise directly from preferences or indirectly from internal production considerations. For example, much of a university's budget includes expenditures that must be maintained because of implicit and...
