Parimutuel principles are widely used as an alternative to fixed odds gambling in which a bookmaker acts as a dealer by quoting fixed rates of return on specified wagers. A parimutuel game is conducted as a call auction in which odds are allowed to fluctuate during the betting period until the betting period is closed or the auction ‘called’. The prices or odds of wagers are set based upon the relative amounts wagered on each risky outcome. In financial microstructure terms, trading under parimutuel principles is characterised by (1) call auction, non‐continuous trading; (2) riskless funding of claim payouts using the amounts paid for all of the claims during the auction; (3) special equilibrium pricing conditions requiring the relative prices of contingent claims equal the relative aggregate amounts wagered on such claims; (4) endogenous determination of unique state prices; and (5) higher efficiency. Recently, a number of large investment banks have adopted a parimutuel mechanism for offering contingent claims on various economic indices, such as the US Nonfarm payroll report and Eurozone Harmonised inflation. Our paper shows how the market microstructure incorporating parimutuel principles for contingent claims which allows for notional transactions, limit orders, and bundling of claims across states is constructed. We prove the existence of a unique price equilibrium for such a market and suggest an algorithm for computing the equilibrium. We also suggest that for a broad class of contingent claims, that the parimutuel microstructure recently deployed offers many advantages over the dominant dealer and exchange continuous time mechanisms. 相似文献

While researchers have extensively documented the equity response to product recalls and subsequent shareholder losses, less attention in the literature has been given to examining the damaging recall attributes. Using 1973–1998 automotive safety recall data, this study identifies the kinds of recalls that cause significant shareholder losses. After constructing an equally-weighted automotive market index to control for industry effects and adjusting the abnormal returns to account for the degree of surprise in the recall announcement, the study estimates both percentage and real dollar abnormal returns. We find that the indirect costs of automotive recalls are likely larger than the direct costs. 相似文献

We develop a unified sequence of models to examine the determinants of price, output, profitability and concentration for different kinds of oligopolistic market. We relate various magnitudes of significance to judges of welfare and to policy makers, such as consumer surplus, profit, or added benefits of employment or trade surplus, to observable magnitudes such as the size and concentration of the market. It emerges that various appropriately formulated Herfindahl indices are useful in several of these relations. We attempt to present results in a way that is useful for empirical investigations and pay particular attention to applications in trade and development. 相似文献

This paper examines the background to, and options for, privatization of state-owned enterprises in the agricultural sector in developing countries. It identifies areas of the sector where privatization is feasible and those likely to remain under government control. It is concluded that, while there is some scope for privatization, it is unlikely to be as extensive as in other sectors since much of the production is already in private hands, there is limited capacity to pay for services and the capability of the private sector is currently low. 相似文献
