This study examines the effects of changing legal and economic pressure on a large manufacturing firm in the 1980s and shows that the firm was able to pursue two potentially contradictory goals: equal employment opportunity compliance and product market competitiveness. The firm's institutionalized affirmative action commitment and diverse local labor market shaped innovations in production and employment practices in a way that encouraged meeting both goals rather than trading off one for the other. 相似文献

Under deregulation, public policies regarding consumer rights and product warranties have shifted. This paper reviews the rationale for lemon laws, state legislation intended to help consumers resolve new car performance, and repair problems. It then compares consumers’ redress under these laws to redress under other remedies. Experience with Vermont's legislation, one of the most aggressive lemon laws, is reviewed and analyzed in detail as the basis for formulating public policy recommendations in this area. 相似文献

This paper develops an equilibrium model in which informational asymmetries about the qualities of products offered for sale are resolved through a mechanism which combines the signalling and costly screening approaches. The model is developed in the context of a capital market setting in which bondholders produce costly information about a firm's a priori imperfectly known earnings distribution and use this information in specifying a bond valuation schedule to the firm. Given this schedule, the firm's optimal choices of debt-equity ratio and debt maturity structure subsequently signal to prospective shareholders the relevant parameters of the firm's earnings distribution. 相似文献

Trading halts increase, rather than reduce, both volume and volatility. Volume (volatility) in the first full trading day after a trading halt is 230 percent (50 to 115 percent) higher than following “pseudohalts”: nonhalt control periods matched on time of day, duration, and absolute net-of-market returns. These results are robust over different halt types and news categories. Higher posthalt volume is observed into the third day while higher posthalt volatility decays within hours. The extent of media coverage is a partial determinant of volume and volatility following both halts and pseudohalts, but a separate halt effect remains after controlling for the media effect. 相似文献

We study majority voting over a bidimensional policy space when the voters’ type space is either uni‐ or bidimensional. We study two voting procedures widely used in the literature. The Stackelberg (ST) procedure assumes that votes are taken one dimension at a time according to an exogenously specified sequence. The Kramer–Shepsle (KS) procedure also assumes that votes are taken separately on each dimension, but not in a sequential way. A vector of policies is a Kramer–Shepsle equilibrium if each component coincides with the majority choice on this dimension given the other components of the vector. We study the existence and uniqueness of the ST and KS equilibria, and we compare them, looking for example at the impact of the ordering of votes for ST and identifying circumstances under which ST and KS equilibria coincide. In the process, we state explicitly the assumptions on the utility function that are needed for these equilibria to be well‐behaved. We especially stress the importance of single‐crossing conditions, and we identify two variants of these assumptions: a marginal version that is imposed on all policy dimensions separately, and a joint version whose definition involves both policy dimensions. 相似文献

Effects of social activity and aging on variables related to individual motivations, community membership, and consumer behavior were tested for 287 late middle-age and 343 elderly respondents living in three rural communities. Those actively involved were more satisfied with aspects of the community than their less active counterparts, and they expressed stronger intentions to shop with local retailers (inshopping). Klderly respondents were more satisfied with their community, and had higher inshopping levels than the late middle-age respondents. Findings suggest an “embeddedness” of market place activity in the social networks of the rural communities. The number and purchasing power of older persons offer opportunities to rural businesses who are alert to the concerns and unmet needs of these consumers. 相似文献

为了掌握福鼎市桐江溪卤乙酸(HAAs)的含量、时空分布规律及其来源,对水体中HAAs化合物进行取样调查。根据桐江溪水文情势及沿岸特点设置10个取样点,于2017年12月及2018年7月按照涨潮、退潮情况分别对水样进行采集,检测HAAs分布情况,同时将卤乙酸(HAAs)与水质特性、涨退潮进行了相关性分析。研究发现,HAAs是普遍存在于桐江溪中的污染物质。其中,一氯乙酸(MCAA)、二氯乙酸(DCAA)、三氯乙酸(TCAA)、一溴乙酸(MBAA)、二溴乙酸(DBAA)等5种卤乙酸(HAA_5)质量浓度为0.44~3.39μg/L;一氯乙酸(MCAA)、二氯乙酸(DCAA)、三氯乙酸(TCAA)、一溴乙酸(MBAA)、二溴乙酸(DBAA)、三溴乙酸(TBAA)、一溴一氯乙酸(BCAA)、一溴二氯乙酸(BDCAA)、二溴一氯乙酸(CBDAA)等9种卤乙酸(HAA_9)质量浓度为0.83~56.15μg/L。桐江溪中HAAs主要为DCAA,TCAA,TBAA 3种,其中DCAA为制药厂及医院排水导致,主要分布在下游;TCAA主要来源于河段上游的农业生产活动;TBAA为上游沸石矿尾矿库受雨水冲刷而流入的Br~-所生成,主要分布于河流中下段。相关性分析结果表明,温度与HAA_5,HAA_9质量浓度呈现正相关,pH值与HAA_5,HAA_9质量浓度呈现负相关;TCAA质量浓度于相同季节不同潮汐及不同季节相同潮汐时均呈现上游高于下游的现象,其他HAAs均不因涨潮、退潮的差异造成质量浓度分布的变化。掌握桐江溪HAAs的含量、时空分布规律及来源,探讨其与水质的相关性,对于净水工艺选择、水厂出水HAAs含量的溯源分析、水体环境风险评估以及研究水生生物体内HAAs的累积效应等有重要意义。 相似文献

The purpose of this study was to explore older consumers' problems and behaviour. Data were collected by interviewing. Responses of 150 older Wisconsin residents were analysed using chi square to determine significant differences in consumer problems and behaviour related to the demographic variables: age, sex, place of residence, marital status and education. The distribution of responses was most frequently influenced by marital status. The demographic variables of age, sex and place of residence were also found to influence the response distribution, although less frequently than marital status; there were no significant differences in responses by education. Based on the findings, recommendations are made for consumer education programmes designed specifically for older persons. 相似文献
