Path dependent option prices are employed to derive implied standard deviations of the underlying security price process without recourse to numerical procedures. We empirically illustrate our methodology by inferring the volatility of gold prices. 相似文献

True Spreads and Equilibrium Prices 总被引:1,自引:0,他引:1
Stocks and other financial assets are traded at prices that lie on a fixed grid determined by the minimum tick size. Observed prices and quoted spreads do not correspond to the equilibrium prices and true spreads that would exist in a market with no minimum tick size. Using Monte Carlo Markov Chain methods, this paper estimates the equilibrium prices and true spreads. For large stocks, most of the quoted spread is attributable to the rounding of prices and the adverse selection component is small. The true spread and the adverse selection component are greater for mid-sized stocks. 相似文献

Turner Broadcasting illustrates how organizational mechanisms can be adapted to prevent a majority owner from imposing costs on minority shareholders through inept management or opportunistic behavior. These mechanisms involve issuing preferred stock with unusual features, concentrating its ownership among a small group of investors, allowing the new preferred shareholders to elect several directors, and requiring supramajority approval of major management decisions by a reconstituted board of directors. The alienability of the preferred stock is restricted to help insure that its ownership stays concentrated and in the hands of those with the specific knowledge and incentives to be effective monitors. 相似文献

Clifford E. Reid 《The Review of Black Political Economy》1990,18(4):5-12
A longitudinal data base is used to estimate racial wage differentials for young nonfarm rural workers for 1968, 1973, and
1978. The empirical results indicate the existence of large wage differentials between young white and young black nonfarm
rural workers of both sexes. The results also indicate that the wage differential for young men has increased over time while
the differential for young women has decreased slightly over time. 相似文献

Rosen's implicit markets approach is used to model and estimate the cost of improving the state of repair of rental housing in existing structures. Particular attention is devoted to potential errors in the measurement of state of repair and to the inconsistent estimates of supply and demand parameters implied by Rosen's original econometric technique. Cost estimates imply that improvements in low-income housing could be provided much less expensively in existing housing than by either public new construction or the Section 8 existing housing program. 相似文献
