Selected AbstractsOPTIONS AND EFFICIENCY IN MULTIDATE SECURITY MARKETSMATHEMATICAL FINANCE, Issue 4 2005Alexandre M. Baptista This paper extends the work of Ross (1976; Q. J. Econ. (90)1, 75,89) to multidate security markets. First, we show that if a primitive security separates states at the terminal date, then there exist multiperiod European options on that security generating dynamically complete markets. Second, we show that if a primitive security conditionally separates states at the terminal date, then there exist multiperiod European options on that security generating generically dynamically complete markets provided that certain conditions hold. Third, we show that there are economies for which the minimum number of multiperiod European options on a primitive security generating generically dynamically complete markets is relatively large. Finally, we show that in these economies, a relatively small number of multiperiod European options on possibly different portfolio strategies of primitive securities generates generically dynamically complete markets. [source] Creating Securities Markets in Developing Countries: A New Approach for the Age of Automated TradingINTERNATIONAL FINANCE, Issue 2 2001Benn Steil The past decade has been one of enormous change in the securities trading industry. Automation of trading systems, led by the continental European exchanges and US ,electronic communications networks' (ECNs), has resulted in significant declines in trading costs, massive increases in turnover, internationalization of trading and settlement system operations, and major reforms in exchange governance. Yet the policy advice given to developing country governments looking to create or expand securitized finance in their markets has been largely unaffected by these developments. This is unfortunate, as developing countries now have the opportunity to leapfrog the evolving infrastructure of the mature markets and to define the global efficient frontier in trading technology, exchange governance, investor access and market structure regulation. This paper analyses the technological and economic forces driving change in the securities trading industry, and examines the implications for developing markets. [source] Generic Existence and Robust Nonexistence of Numéraires in Finite Dimensional Securities MarketsMATHEMATICAL FINANCE, Issue 4 2000Bruno Girotto A numéraire is a portfolio that, if prices and dividends are denominated in its units, admits an equivalent martingale measure that transforms all gains processes into martingales. We first supply a necessary and sufficient condition for the generic existence of numéraires in a finite dimensional setting. We then characterize the arbitrage-free prices and dividends for which the absence of numéraires survives any small perturbation preserving no arbitrage. Finally, we identify the cases when any small, but otherwise arbitrary, perturbation of prices and dividends preserves either the existence of numéraires, or their nonexistence under no arbitrage. [source] "You Can Enter but You Cannot Leave,": U.S. Securities Markets and Foreign FirmsTHE JOURNAL OF FINANCE, Issue 5 2008ANDRÁS MAROSI ABSTRACT Although a number of prior papers have argued the benefits to foreign firms of cross-listing their shares in the U.S., the number of foreign firms exiting U.S. capital markets has been increasing. This has occurred despite the difficulties foreign firms face in deregistering from the Securities and Exchange Commission (SEC). This paper examines the reasons underlying this trend. One of our main findings is that the passage of the Sarbanes-Oxley Act has reduced the net benefits of a U.S. listing and registration, particularly for smaller foreign firms with lower trading volume and stronger insider control. [source] International Portfolio Investment: Theory, Evidence, and Institutional FrameworkFINANCIAL MARKETS, INSTITUTIONS & INSTRUMENTS, Issue 3 2001Söhnke M. Bartram At first sight, the idea of investing internationally seems exciting and full of promise because of the many benefits of international portfolio investment. By investing in foreign securities, investors can participate in the growth of other countries, hedge their consumption basket against exchange rate risk, realize diversification effects and take advantage of market segmentation on a global scale. Even though these advantages might appear attractive, the risks of and constraints for international portfolio investment must not be overlooked. In an international context, financial investments are not only subject to currency risk and political risk, but there are many institutional constraints and barriers, significant among them a host of tax issues. These constraints, while being reduced by technology and policy, support the case for internationally segmented securities markets, with concomitant benefits for those who manage to overcome the barriers in an effective manner. [source] Setting the rules: private power, political underpinnings, and legitimacy in global monetary and financial governanceINTERNATIONAL AFFAIRS, Issue 3 2008GEOFFREY R. D. UNDERHILL The role of private market agents in global monetary and financial governance has increased as globalization has proceeded. This shift in both markets and patterns of governance has often been encouraged by states themselves in pursuit of liberalization policies. Much of the literature views these developments in a positive light, yet there are other aspects of these developments that also merit attention. This article supports its central propositions with two cases of emerging global financial governance processes: the Basel II capital adequacy standards for international banking supervision and the International Organization of Securities Commissions-based transnational regulatory processes underpinning the functioning of cross-border securities markets. Based on the case findings, the article argues first that private sector self-regulation and/or public-private partnership in governance processes can leave public authorities vulnerable to dependence on the information and expertise provided by private agents in a fast-moving market environment. Policy in the vital domain of financial regulation has been increasingly aligned to private sector preferences to a degree that should raise fears of bureaucratic capture. Second, the article contends that the overall outcome in terms of global financial system efficiency and stability has been mixed, bringing a range of important benefits but also instability and crisis for many societies to a degree that has led to challenges to global governance itself. The case material indicates that the input, output and accountability phases of legitimacy in global monetary and financial governance are highly problematic, and much of the problem relates to the way in which private market agents are integrated into the decision-making process. Third, the article posits that a better consideration of these three ,phases' of legitimacy and their interrelationships is likely to enhance the political underpinnings and legitimacy of global financial and monetary order. [source] Private Enforcement of Corporate Law: An Empirical Comparison of the United Kingdom and the United StatesJOURNAL OF EMPIRICAL LEGAL STUDIES, Issue 4 2009John Armour It is often assumed that strong securities markets require good legal protection of minority shareholders. This implies both "good" law,principally, corporate and securities law,and enforcement, yet there has been little empirical analysis of enforcement. We study private enforcement of corporate law in two common-law jurisdictions with highly developed stock markets, the United Kingdom and the United States, examining how often directors of publicly traded companies are sued, and the nature and outcomes of those suits. We find, based a comprehensive search for filings over 2004,2006, that lawsuits against directors of public companies alleging breach of duty are nearly nonexistent in the United Kingdom. The United States is more litigious, but we still find, based on a nationwide search of court decisions between 2000,2007, that only a small percentage of public companies face a lawsuit against directors alleging a breach of duty that is sufficiently contentious to result in a reported judicial opinion, and a substantial fraction of these cases are dismissed. We examine possible substitutes in the United Kingdom for formal private enforcement of corporate law and find some evidence of substitutes, especially for takeover litigation. Nonetheless, our results suggest that formal private enforcement of corporate law is less central to strong securities markets than might be anticipated. [source] SOME REMARKS ON ARBITRAGE AND PREFERENCES IN SECURITIES MARKET MODELSMATHEMATICAL FINANCE, Issue 3 2004Marco Frittelli We introduce the notion of a market-free-lunch that depends on the preferences of all agents participating in the market. In semimartingale models of securities markets, we characterize no arbitrage (NA) and no-free-lunch-with-vanishing-risk (NFLVR) in terms of the market-free-lunch and show that the difference between NA and NFLVR consists in the selection of the class of monotone, respectively monotone and continuous, utility functions that determines the absence of the market-free-lunch. We also provide a direct proof of the equivalence between the absence of a market-free-lunch, with respect to monotone concave preferences, and the existence of an equivalent (local/sigma) martingale measure. [source] No Arbitrage in Discrete Time Under Portfolio ConstraintsMATHEMATICAL FINANCE, Issue 3 2001Laurence Carassus In frictionless securities markets, the characterization of the no-arbitrage condition by the existence of equivalent martingale measures in discrete time is known as the fundamental theorem of asset pricing. In the presence of convex constraints on the trading strategies, we extend this theorem under a closedness condition and a nondegeneracy assumption. We then provide connections with the superreplication problem solved in Föllmer and Kramkov (1997). [source] Impact of the QFII Scheme on Investment-Cash Flow Sensitivity,ASIA-PACIFIC JOURNAL OF FINANCIAL STUDIES, Issue 3 2009Jung-Hua Hung Abstract Taiwan is an important emerging economy which has adopted a progressive strategy to open up its securities markets, mainly through the QFII (Qualified Foreign Institutional Investor) scheme. This paper examines Taiwan's QFII experience so as to determine whether the implementation of such a policy has helped reduce corporate investment-cash flow sensitivity. Empirical results suggest that the launching of the QFII program as an interim institutionalization strategy to attract foreign capital into Taiwan's securities markets has been successful in relaxing corporations' investment-cash flow sensitivity. [source] Capital Markets Regulation: How Can Accounting Research Contribute?AUSTRALIAN ACCOUNTING REVIEW, Issue 4 2009Stephen Taylor In examining the possible contribution that accounting research can play in ensuring effective and efficient regulation of securities markets, two principal opportunities stand out. First, the role of research in informing debate about proposed regulatory intervention (ex ante contribution to regulatory debate). Second, the ability of research to inform analysis as to the effectiveness of previously implemented regulatory changes (ex post contribution to regulatory debate). In the ex ante case, there is a natural tension between the way in which regulatory initiatives often arise quickly and the inevitable passage of time required to fully appreciate the degree to which underlying problems have been correctly characterised and can be framed in a manner suitable for addressing via rigorous analytical and empirical research. It is also impossible to empirically assess the effect of regulatory intervention that has not yet occurred. Finally, if data are simply not available, then research is limited to analytical analysis and prediction. In the ex post case, there is often a natural reluctance to subject regulatory intervention to mandatory analysis, and even when a statutory requirement exists for such analysis and review, the time horizon is often far too short for meaningful analysis. In both the ex ante and ex post cases, what is unavoidable is that regulation can only be legitimately informed by research that is sufficiently rigorous so as to have robust conclusions. Assessing research on these dimensions means that transparency is required so as to allow researchers to engage in meaningful debate about the validity of the conclusions. This inevitably means that research needs to be a partnership between regulatory agencies and academia, and that when research is used to justify regulatory interventions it must be publicly available and subject to robust debate. [source] Neural Network Earnings per Share Forecasting Models: A Comparative Analysis of Alternative MethodsDECISION SCIENCES, Issue 2 2004Wei Zhang ABSTRACT In this paper, we present a comparative analysis of the forecasting accuracy of univariate and multivariate linear models that incorporate fundamental accounting variables (i.e., inventory, accounts receivable, and so on) with the forecast accuracy of neural network models. Unique to this study is the focus of our comparison on the multivariate models to examine whether the neural network models incorporating the fundamental accounting variables can generate more accurate forecasts of future earnings than the models assuming a linear combination of these same variables. We investigate four types of models: univariate-linear, multivariate-linear, univariate-neural network, and multivariate-neural network using a sample of 283 firms spanning 41 industries. This study shows that the application of the neural network approach incorporating fundamental accounting variables results in forecasts that are more accurate than linear forecasting models. The results also reveal limitations of the forecasting capacity of investors in the security market when compared to neural network models.

[source] Long-term information, short-lived securitiesTHE JOURNAL OF FUTURES MARKETS, Issue 5 2006Dan Bernhardt The authors explore strategic trade in short-lived securities by agents who have private information that is potentially long-term, but do not know how long their information will remain private. Trading short-lived securities is profitable only if enough of the private information becomes public prior to contract expiration; otherwise the security will worthlessly expire. How this results in trading behavior fundamentally different from that observed in standard models of informed trading in equity is highlighted. Specifically, it is shown that informed speculators are more reluctant to trade shorter-term securities too far in advance of when their information will necessarily be made public, and that existing positions in a shorter-term security make future purchases more attractive. Because informed speculators prefer longer-term securities, this can make trading shorter-term contracts more attractive for liquidity traders. The conditions are characterized under which liquidity traders choose to incur extra costs to roll over short-term positions rather than trade in distant contracts, providing an explanation for why most longer-term derivative security markets have little liquidity and large bid-ask spreads. © 2006 Wiley Periodicals, Inc.
