This study examined the life experiences of adults and their effect on perceptions of leisure. Data for this study came from A Study of Leisure during Adulthood (ASOLDA), a 10-year study of the values, attitudes, and perceived freedom in leisure of 84 adults. Individual growth curve modeling was used to explore patterns and change within leisure domains for the sample. Life structure predicted adults’ perceived freedom in leisure while life events were predictive of adults’ leisure attitudes. Data from interviews were used to supplement the survey data to provide a better understanding of the predictors of leisure perceptions in this study.  相似文献

Earnings non‐synchronicity reflects the extent to which firm‐specific factors determine a firm's earnings. Prior research suggests that high earnings non‐synchronicity impedes corporate outsiders' ability to process information. This study examines the impact of earnings non‐synchronicity on managers' decisions to provide earnings forecasts. We propose that high earnings non‐synchronicity motivates managers to issue earnings forecasts to reduce information asymmetry between managers and investors and to preempt costly information acquisition by outsiders. Consistently, we find a positive relation between earnings non‐synchronicity and managers' propensity to issue earnings forecasts, particularly long‐horizon forecasts. This positive relation is weaker when earnings are easier to predict based on the firm's earnings history and is stronger when the firm has higher institutional ownership and greater analyst following. We also find that the market's reaction to management forecasts increases with earnings non‐synchronicity. Overall, the evidence suggests that managers voluntarily provide earnings forecasts to alleviate the adverse consequences of earnings non‐synchronicity. These findings provide a more complete picture about the impact of earnings non‐synchronicity on a firm's information environment, and highlight the effect of the nature of information asymmetry on voluntary disclosures.  相似文献

Do immigrants undermine culture in a way that destroys productivity in destination countries? Some scholars have argued that because immigrants come from countries with dysfunctional social capital—norms and institutions—they will import it and pollute the social capital in destination countries. One potential channel through which this could occur is corruption. We examine stocks and flows of immigrants over a 20‐year time period to see if corruption increased in destination countries. We generally find that immigration is not associated with increases in corruption. Additionally, we find that immigration tends to decrease corruption in destination countries with low levels of corruption or high levels of economic freedom.  相似文献

Muhammad Ali, who ruled Egypt between 1805 and 1849, intervened in Egyptian markets in an attempt to foster industrialization, especially between 1812 and 1840. Like a modern marketing board, the state purchased agricultural commodities (cotton and wheat) at low prices and sold them on world markets at much higher prices, a policy equivalent to an export tax. Ali also replaced tax farming with his own land taxes. The revenues so derived were used in part to finance manufacturing investment and to build irrigation canals. In addition, Ali supplied flax and cotton at those cheap purchase prices to domestic textile manufacturing, thus subsidizing the industry. He also used non‐tariff barriers to exclude foreign competition from domestic markets. Were Ali's state‐led policies successful in fostering industry? The answer is no easier to extract from this phase of Egyptian history than from that of other poor countries at that time. This is because Egypt faced the same terms of trade boom typical of most poor commodity exporters, which was causing de‐industrialization everywhere else in the poor periphery. Ali picked a very difficult time to pursue his agenda, but we show that his policies were successful.  相似文献

We analyse the degree of polarisation in the international distribution of CO2 emissions per capita in the European Union. It is analytically relevant to examine the degree of instability inherent to a distribution and, in the analysed case, the likelihood that the distribution and its evolution will increase or decrease the chances of reaching an agreement on climate policy. Two approaches were used to measure polarisation: the endogenous approach, in which countries are grouped according to their similarity in terms of emissions, and the exogenous approach, in which countries are grouped geographically. Our findings indicate a clear decrease in polarisation since the mid-1990s, which can essentially be explained by the fact that the different groups have converged (i.e. antagonism among the CO2 emitters has decreased) as the contribution of energy intensity to between-group differences has decreased. This lower degree of polarisation in CO2 distribution suggests a situation more conducive to the possibility of reaching EU-wide agreements on the mitigation of CO2 emissions.  相似文献

The article presents a review of current theoretical and empirical approaches to sex work, followed by the presentation of an original theoretical framework (Della Giusta et al., 2006), which is tested with an econometric model of the characteristics of demand for sex services by a sample of clients of street sex workers in the US. We present findings in relation to stigma and the relationship between paid and unpaid sex that corroborate our model's hypotheses and are in line with findings from other empirical studies. Furthermore, we identify in our sample two diametrically opposite profiles: one for clients whom we label ‘experimenters’, and one for more experienced ones that we name ‘regulars’, we also estimate attitudes toward risk, and draw implications in terms of both policy and future theoretical and empirical research.  相似文献

We describe the regulatory regime under which international trucking operated in Western Europe until the mid-1980s, the deregulatory process that followed, and the effect of this deregulation. We find that deregulation had a large positive effect on the growth of international trucking. We also find that shippers shifted toward more outsourcing of their trucking needs, but this occurred to an even greater extent in local and national road transport. We conclude that other factors beside the deregulation of international trucking affected the organization of the industry at the time. Finally, despite concerns voiced by member countries, we find no evidence that deregulation disproportionately favored carriers of countries that were initially more (or less) involved in international trucking, nor that it has favored low-wage countries.   相似文献

Along with the explosive growth of the phenomenon Online Social Networks (OSN), identifying influential users in OSN has received a great deal of attention in recent years. However, the development of practical approaches for identifying them is still in its infancy. By means of a structured literature review, the authors analyze and synthesize the publications particularly from two perspectives. From a research perspective, they find that existing approaches mostly build on users’ connectivity and activity but hardly consider further characteristics of influential users. Moreover, they outline two major research streams. It becomes apparent that most marketing-oriented articles draw on real-world data of OSN, while more technology-oriented papers rather have a theoretical approach and mostly evaluate their artifacts by means of formal proofs. The authors find that a stronger collaboration between the scientific Business and Information Systems Engineering (BISE) and Marketing communities could be mutually beneficial. With respect to a practitioner’s perspective, they compile advice on the practical application of approaches for the identification of influential users. It is hoped that the results can stimulate and guide future research.  相似文献

Compliance with food safety recommendations was assessed among 357 university undergraduates, 112 males (31%) and 245 females (69%), in the context of the health belief model. Concerning meats, 87% of the students complied with purchasing, 75% with storage, and 42% with preparation recommendations often/always. Compliance was high with recommended purchasing (96%) and storage (99%) practices for raw eggs, but only 55% of students prepared eggs safely. Overall, the health belief model was a poor predictor of compliance with food‐safety recommendations. Findings suggest that college students would benefit from interventions focusing on the causes of microbial food contamination and those that assist them in overcoming perceived barriers to adopting safe food‐handling practices. Also, validated instruments are needed to help family and consumer sciences educators identify college students who are noncompliant with food‐safety recommendations.  相似文献

In this paper we consider the problem of hedging an arithmetic Asian option with discrete monitoring in an exponential Lévy model by deriving backward recursive integrals for the price sensitivities of the option. The procedure is applied to the analysis of the performance of the delta and delta–gamma hedges in an incomplete market; particular attention is paid to the hedging error and the impact of model error on the quality of the chosen hedging strategy. The numerical analysis shows the impact of jump risk on the hedging error of the option position, and the importance of including traded options in the hedging portfolio for the reduction of this risk.  相似文献
