This study takes a qualitative, point‐in‐time look at 26 females’ decision‐making processes toward trading off the risks of mercury and the health benefits of a seafood diet. The data revealed five different decision‐making processes, with 17 of the 26 participants indicating their fish consumption patterns did not change. Of the nine who changed their fish consumption in some way, six specifically reduced the amount of tuna they ate. Similarly, participants who were most at risk—women of childbearing age and those with young children—expressed fish consumption changes more frequently than others, especially in the amount of tuna they consumed.  相似文献

This study examines associations between measures of stock exchange disclosure and market development at 50 of the member stock exchanges of the World Federation of Exchanges. We focus on stock exchange disclosure systems (rather than actual company disclosures) because this approach links stock exchange policy with desired outcomes related to market development (such as liquidity, trading activity, and market size relative to gross domestic product). We find strong support for the hypothesis that the strength of the disclosure system (disclosure rules, monitoring, and enforcement) is positively associated with market development, after controlling for legal system, legal protection of investors, market size, and several other potentially relevant explanatory variables.  相似文献

The purpose of this research was to investigate the disinfectant action of a heavy-duty biological detergent at low and recommended washing temperatures. The effectiveness of the process was measured in terms of the removal, transfer and destruction of bacteria from infected test pieces. The results indicate that reducing the washing temperature decreases the degree of disinfection and increases the cross-infection of any articles washed in the same load. Evidence is also obtained that shows that the presence of detergent is more important than the washing temperature for disinfectant action.  相似文献

We develop a model with heterogeneity in skills to study the effect of tax progressivity on economic growth. The probability of becoming skilled depends positively on expenses on teacher time. We consider growth resulting from an externality due to skilled workers and from their employment in research and development. We show changes in the progressivity of taxes can have growth effects even when changes in flat rate taxes have none. The response is stronger with externality‐driven growth. Progressive taxation, often suggested to reduce inequality, can increase the long‐run skill premium and decrease the upward mobility of the poor.  相似文献

This paper examines the relation between cognitive perceptions of management and firm valuation. We develop a composite measure of investor perception using 30‐second content‐filtered video clips of initial public offering (IPO) roadshow presentations. We show that this measure, designed to capture viewers’ overall perceptions of a CEO, is positively associated with pricing at all stages of the IPO (proposed price, offer price, and end of first day of trading). The result is robust to controls for traditional determinants of firm value. We also show that firms with highly perceived management are more likely to be matched to high‐quality underwriters. In further exploratory analyses, we find the impact is greater for firms with more uncertain language in their written S‐1. Taken together, our results provide evidence that investors’ instinctive perceptions of management are incorporated into their assessments of firm value.  相似文献

A field experiment was conducted on a stratified sample of 354 recyclers and nonrecyclers to test the effects of coupon incentives on consumers' intentions and behavior in recycling aluminum. Results indicate that modest coupon incentives positively influenced recyclers' behavior, but did not influence nonrecyclers. Over the range of incentives tested, evidence suggests that increased recycling frequency is directly related to the coupon value. Implications for incorporating coupon promotional programs into the development of energy conservation policy, and areas for future research are discussed.  相似文献
