This paper examines the issue of fraud on the Internet and discusses three areas with significant potential for misleading and fraudulent practices, namely: securities sales and trading; electronic commerce; and the rapid growth of Internet companies. The first section of the paper discusses securities fraud on the Internet. Activities that violate US securities laws are being conducted through...

We examine network effects as an impediment to optimal financial contracting. In devising the terms of their transaction, the parties may prefer to conform to a market standard rather than matching their own contracting needs. To study this possibility, we investigate choice of contract law provisions in European debt securities. In order to disentangle network effects from the effects of subst...

Cross-border equity and long-term debt securities portfolio investment networks are analysed from 2002 to 2012, covering the 2008 global financial crisis. They serve as network-proxies for measuring the robustness of the global financial system and the interdependence of financial markets, respectively. Two early-warning indicators for financial crises are identified: First, the algebraic conne...

We argue that reluctance to invest in drug treatments to fight the AIDS epidemics in developing countries is largely motivated by severe losses occurring from the future albeit uncertain appearance of a curative vaccine. We design a set of securities generating full insurance coverage against such losses, while achieving full risk-sharing with vaccine development agencies. In a General Equilibr...

In this paper, we consider a model of valuing callable financial securities when the underlying asset price dynamic is modeled by a regime switching process. The callable securities enable both an issuer and an investor to exercise their rights to call. We show that such a model can be formulated as a coupled stochastic game for the optimal stopping problem with two sopping boundaries. We provi...

Recent years have seen the introduction of a new class of derivative securities based on "exotic underlyings" such as natural catastrophes and weather. This paper analyzes the pros and cons of these new securities as assets for institutional investors. It is argued that the underlyings on which these derivatives trade have very low correlations with other factors that move the investment market...

The business environment is full of uncertainty. Allocating the wealth among various asset classes may lower the risk of overall portfolio and increase the potential for more benefit over the long term. In this paper, we propose a mixed singlestage R&D projects and multi-stage securities portfolio selection model. Specifically, we present a bi-objective mixed-integer stochastic programming mode...

A quantum financial approach to finite games of strategy is addressed, with an extension of Nash’s theorem to the quantum financial setting, allowing for an entanglement of games of strategy with two-period financial allocation problems that are expressed in terms of: the consumption plans’ optimization problem in pure exchange economies and the finite-state securities market optimization probl...

We consider the problem of tracking a benchmark target portfolio of financial securities in particular the S&P 500. Linear integer programming models are developed that seeks to track a target portfolio using a strict subset of securities from the benchmark portfolio. The models represent a clustering approach to select securities and also include additional constraints that aim to control risk...

On April 8-9, 1999, more than sixty securities lawyers, regulators, and academics participated in a roundtable discussion in Washington, D.C., on what should be the future content of the U.S. securities laws. The full participant list (excluding, however, SEC personnel) appears in the Appendix of this report. The conference’s co-conveners were Mr. Edward F. Greene of Cleary, Gottlieb, Steen & H...
