Several countries have adopted legally separated share markets (LSSM), where local firms market separate claims to the same dividend flow to domestic and foreign investors who cannot arbitrage across LSSM. We designed a laboratory experiment to test whether the inside information in one LSSM is reflected in the prices of both markets. We find that insider information does transfer across markets. The extent of this transfer depends upon whether the location of insiders is publicly known, how close prices in the informed market get to the full information equilibrium, and how much the price variance is in this market. We also observe insiders' behavior and performance under different market conditions. Efforts by insiders to manipulate the market increase when their location is unknown to the public. On average such efforts pay off to the whole group of insiders but not to the initiator of these manipulative transactions.  相似文献

In power struggles, the strong might be expected to grow ever stronger and the weak weaker still. But in actuality, poorer or smaller combatants often end up improving their position relative to richer or larger ones. This is the paradox of power. The explanation is that initially poorer contenders are rationally motivated to fight harder, to invest relatively more in conflictual activity. Only when the decisiveness of conflict is sufficiently high does the richer side gain relatively in terms of achieved income. Among other things, the paradox of power explains political redistributions of income from the rich to the poor.  相似文献

Seasonal variability is an important source of risk faced by farmers and, regardless of an individual's attitude to risk, there are options to tactically adjust production strategies as the outcomes of risk become known. The objective of this article is to measure the economic benefits of alternative approaches to managing weeds, one of the most serious production problems in Australian cropping systems. A bioeconomic model that combines weed biology, crop growth and economics is developed to value the effects of seasonal variability and the role of tactical responses and sequential decision making in determining an optimal integrated weed management strategy. This shows that there are substantial differences in the measured long‐term benefits from deterministic and stochastic simulations. It is concluded that, for research evaluation of technologies that involve complex biological and dynamic systems, ignoring the impacts of seasonal variability, responses to risk and sequential decision making can lead to an incorrect estimate of the economic benefits of a technology. In this case study of optimal weed management strategies in Australia, the size of the error is high.  相似文献

African agricultural production is modeled as a sequential decision process, with men's labor first allotted to clearing, then women's labor allotted to harvesting. A switching regression is then used to measure the constraints due to clearing labor capacity and harvesting labor capacity. The import of men's clearing labor depends on the valuation of shadow wages. Output appears to be more frequently constrained by husband's clearing labor, and in this situation male labor appears under‐utilized. However, output is also significantly constrained by female harvest labor, although the findings imply that female labor is over‐utilized at this stage.  相似文献

We examine the usefulness and credibility of analyst recommendations by focusing on their behavior surrounding tender offer announcements. For our 1998–2001 sample, we find analysts did not identify takeover targets through their recommendations nor did they distinguish between wealth‐increasing and wealth‐decreasing tender offers. We find some evidence of conflicts of interest in analyst recommendations, but it is confined to the 1999–2000 dot‐com period. However, the long‐run performance following recommendations suggests that these conflicts have little ultimate cost to investors.  相似文献

Synopsis Neuroeconomics rightly has been claimed to be a natural extension of bioeconomics. One of the things bioeconomics investigates is what behavioral dispositions and what behavioral patterns evolutionary processes have produced. Neuroeconomics extends this to the study of evolved mechanisms that are at work in decision-making at the neural level of the brain. The paper argues that in another respect neuroeconomics and bioeconomics are discontinuous, however. Bioeconomics maintains that the applicability of standard economic theory’s constrained maximization framework is not confined to human behavior. The constrained maximization framework is believed to be suitable to describe behavior throughout the animal kingdom. By contrast, despite some minor internal disagreements all neuroeconomists seem to agree that human behavior is predicted poorly by standard economic theory in several social and economic situations. Neuroscience is believed to hold out the hope of an advanced understanding of when and why this is the case.   相似文献

Two‐part pricing, price‐discrimination, rent creation and extraction, principal–agent theory, and public choice perspectives on public bureaucracies are used to interpret a vendor‐license marketing arrangement and controversy arising out of the 1996 Olympic Games in Atlanta, GA. Containing features predicted by principal–agency theory, Atlanta's arrangement with its marketing agent was a response to the behavior of public bureaucracies and a low cost method of converting visitors' consumer surplus to rent, which could be extracted by the marketing agent and then by Atlanta. Atlanta's incentive to enforce vendor property rights was influenced by the nature of the game between Atlanta and prospective vendors. Copyright © 2001 John Wiley & Sons, Ltd.  相似文献

This research extends the binomial option-pricing model of Cox, Ross, and Rubinstein (1979) and Rendleman and Barter (1979) to the case where the up and down percentage changes of stock prices are stochastic. Assuming stochastic parameters in the discrete-time binomial option pricing is analogous to assuming stochastic volatility in the continuous-time option pricing. By assuming that the up and down parameters are independent random variables following beta distributions, we are able to derive a closed-form solution to this stochastic discrete-time option pricing. We also derive an upper and a lower bounds of the option price.  相似文献

This paper examines the negative market impact that resulted from the insurance regulators’ potential reclassification of 140 hybrid capital securities in spring and summer 2006. It illustrates how financial contagion can spring from a regulatory policy change that lacks transparency. We investigate the impact of the uncertainty surrounding the regulators’ true classification criteria by measuring the effect of the reclassification announcements on hybrid new issue volume, cumulative average abnormal returns, bid‐ask spreads, and yield spreads. The financial contagion adversely affected the entire hybrid capital securities market for six months. The effect was most pronounced among those hybrids that were eventually reclassified as common equity equivalents. It was greater for Yankee Tier 1 hybrids, which had been more popular with insurance firm investors prior to the reclassifications, than among non‐Tier 1 hybrids.  相似文献
