In this article we compare bivariate and multivariate models for homogamy of social origin and education to test whether bivariate models of homogamy lead to biased results. We use data on Hungarian couples married between 1930 and 1979 and loglinear models of scaled association. The results indicate some differences between bivariate and multivariate analyses. At each point of time bivariate models overestimate homogamy, both with respect to education and social origin. However, results on trends in time do not differ much between the two analyses. The exception is the period 1940–1959, in which bivariate analysis showed decreasing educational homogamy, and multivariate analysis showed an increasing trend. The latter finding can be explained by declining homogamy of social origin, as well as the weaker reproduction and cross-effects in this period.  相似文献

Open-bank assistance (OBA), provided to troubled banking institutions by the FDIC to prevent their failure, has been criticized extensively on grounds that closed-bank transactions, especially early closed bank transactions, are less expensive to the FDIC. This article analyzes a case in which OBA makes public policy sense, under conditions in which uncertainty is introduced into the valuation of a bank's nonperforming assets. Under such uncertainty, the FDIC may play a role by providing to the acquiror of the troubled institution essentially costless (to the FDIC) standby insurance on the ultimate workout values of the nonperforming assets. If properly structured, such an OBA transaction would meet critics' objections by minimizing FDIC cost and creating incentives for the early recapilization of troubled banks.  相似文献

Previous studies document a significant positive price reaction at the proposal of a buyout offer. In this study the author examines the influence of investment banking relationships on target firms associated with buyout offers. The results support the hypothesis that knowledge of an impending buyout manifests itself before a buyout’s public announcement. The evidence supports the hypothesis that investment bankers use different strategies before a buyout.  相似文献

Under fairly general conditions, the article derives the equilibrium price schedule determined by the bids and offers in an open limit order book. The analysis shows: (1) the order book has a small-trade positive bid-ask spread, and limit orders profit from small trades; (2) the electronic exchange provides as much liquidity as possible in extreme situations; (3) the limit order book does not invite competition from third market dealers, while other trading institutions do; (4) If an entering exchange earns nonnegative trading profits, the consolidated price schedule matches the limit order book price schedule.  相似文献

The Behavioral Perspective Model of purchase and consumption (BPM) portrays the rate at which consumer behaviors take place as a function of the relative openness of the setting in which they occur and the informational and hedonic reinforcement available in or promised by the setting. Each of eight combinations of contingencies based on these explanatory variables is uniquely related to a specific mode of observed consumer behavior. By providing an environmental perspective on consumer behavior, the model makes a critical contribution to the development of contemporary consumer research that frequently decontextualizes its subject matter. It also presents an innovative conceptualization of the nature of marketing strategies.  相似文献

The price movements of certain assets can be modeled by stochastic processes that combine continuous diffusion with discrete jumps. This paper compares values of options on assets with no jumps, jumps of fixed size, and jumps drawn from a lognormal distribution. It is shown that not only the magnitude but also the direction of the mispricing of the Black-Scholes model relative to jump models can vary with the distribution family of the jump component. This paper also discusses a methodology for the numerical valuation, via a backward induction algorithm, of American options on a jump-diffusion asset whose early exercise may be profitable. These cannot, in general, be accurately priced using analytic models. The procedure has the further advantage of being easily adaptable to nonanalytic, empirical distributions of period returns and to nonstationarity in the underlying diffusion process.  相似文献

The article considers six standard arguments in favour of an unfettered free market: (1) the freedom to consume; (2) the freedom of the seller; (3) the freedom of the producer; (4) freedom from government interference; (5) lower costs; (6) promotion of democracy. It demonstrates that each of these arguments turns out to be incoherent on closer examination. The ground of this incoherence it is shown, is the market doctrine's systematic omission of non-business costs and benefits from its analysis, a methodological blindness which can only be overcome by a wider-lensed comprehension of economic value.  相似文献
