To model the evolution of strategic intelligence, player types are drawn from a hierarchy of "smartness" analogous to the levels of iterated rationalizability. Nonrationalizable strategies die out, but when higher levels of smartness incur maintenance costs, being right is always as good as being smart. Moreover, if a manifest way to play emerges, then dumb players never die out, while smarter players with positive maintenance costs vanish. These results call to question the standard game-theoretic assumption of super-intelligent players. Journal of Economic Literature Classification Numbers: B40, C70, C72, C73.  相似文献

A central objective of port privatization and/or deregulation policies is stimulating greater efficiency by engendering a more competitive market and commercial approach to management. Korea provides a prime example of a nation that is implementing such policies. Also, its ports play a pivotal role in world shipping, particularly in the ever-burgeoning container market. The success of these policies in increasing the productive efficiency of Korean container terminals is assessed. The UK container terminal sector provides a useful benchmark for comparison since privatization and deregulation have formed an integral part of UK port reforms for nearly 20 years and the effect on efficiency, having had time to mature, will be much easier to gauge. The stochastic frontier model is justified as the chosen methodology for estimating productive efficiency levels and is applied to cross-sectional data under a variety of distributional assumptions. A panel data model is also estimated. Results are consistent and suggest (1) The degree of private sector involvement in sample container terminals is positively related to productive efficiency and (2) Improved productive efficiency has followed the implementation of privatization and deregulation policies within the Korean sector. Even though not categorical, these conclusions are important because the market for container throughput is internationally competitive and if policies which promote competition between Korean container terminals lead to greater productive efficiency, this will inevitably make the sector as a whole more competitive internationally.  相似文献

Canadian men in the top earnings ventile live eight years (11%) longer than do men in the bottom ventile. For women, the difference is 3.6 years. This earnings–longevity gradient has shifted uniformly across earnings groups through time, in stark contrast to in the US. We demonstrate that the widely used period measurement method can differ from cohort measures. For middle‐aged men, we find a recent slowdown of mortality improvements, echoing the situation in the US. With comparable data, the Canadian earnings–longevity gradient is half the US gradient; but one quarter of this gap may result from Canada–US earnings differences.  相似文献

Objective: To provide an estimate of the annual number of super-refractory status epilepticus (SRSE) cases in the US and to evaluate utilization of hospital resources by these patients.

Methods: The Premier Hospital Database was utilized to estimate the number of SRSE cases based on hospital discharges during 2012. Discharges were classified as SRSE cases based on an algorithm using seizure-related International Classification of Diseases-9 (ICD-9) codes, Intensive Care Unit (ICU) length of stay (LOS), and treatment protocols (e.g. benzodiazepines, anti-epileptic drugs (AEDs), and ventilator use). Secondary analyses were conducted using more restrictive algorithms for SRSE.

Results: A total of 6,325 hospital discharges were classified as SRSE cases from a total of 5,300,000 hospital discharges. Applying a weighting based on hospital characteristics and 2012?US demographics, this projected to an estimated 41,156 cases of SRSE in the US during 2012, an estimated incidence rate of ~13/100,000 annually for SRSE in the US. Secondary analyses using stricter SRSE algorithms resulted in estimated incidence rates of ~11/100,000 and 8/100,000 annually. The mean LOS for SRSE hospitalizations was 16.5 days (median =11; interquartile range [IQR]?=?6–20), and the mean ICU LOS was 9.3 days (median =6; IQR =3–12). The mean cost of an SRSE hospitalization was $51,247 (median = $33,294; 95% CI = $49,634–$52,861).

Limitations: The analysis uses ICD-9 diagnostic codes and claims information, and there are inherent limitations in any methodology based on treatment protocol, which created challenges in distinguishing with complete accuracy between SRSE, RSE, and SE on the basis of care patterns in the database.

Conclusion: SRSE is associated with high mortality and morbidity, which place a high burden on healthcare resources. Projections based upon the findings of this study suggest an estimated 25,821–41,959 cases of SRSE may occur in the US each year, but more in-depth studies are required.  相似文献

Considerable effort has been exercised in estimating mean returns to education while carefully considering biases arising from unmeasured ability and measurement error. Recent work has investigated whether there are variations from the “mean” return to education across the population with mixed results. We use an instrumental variables estimator for quantile regression on a sample of twins to estimate an entire family of returns to education at different quantiles of the conditional distribution of wages while addressing simultaneity and measurement error biases. We test whether there is individual heterogeneity in returns to education and find that: more able individuals obtain more schooling perhaps due to lower marginal costs and/or higher marginal benefits of schooling and that higher ability individuals (those further to the right in the conditional distribution of wages) have higher returns to schooling consistent with a non-trivial interaction between schooling and unobserved abilities in the generation of earnings. The estimated returns are never lower than 9 percent and can be as high as 13 percent at the top of the conditional distribution of wages but they vary significantly only along the lower to middle quantiles. Our findings may have meaningful implications for the design of educational policies.  相似文献

Does the presence of corporate headquarters in a city affect the incomes of local charities? To address this question we combine data on the head office locations of publicly traded U.S. firms with information on the receipts of local charitable organizations. Cities like Houston, San Jose, and San Francisco gained significant numbers of corporate headquarters over the past two decades, while cities like Chicago and Los Angeles lost. Our analysis suggests that attracting or retaining the headquarters of a publicly traded firm yields approximately $3–10 million per year in contributions to local non-profits. Likewise, each $1000 increase in the market value of the firms headquartered in a city yields $0.60–1.60 to local non-profits. Most of the increase in charitable contributions is attributable to an effect on the number of highly-compensated individuals in a city, rather than through direct donations by the corporations themselves. The increased private sector donations from the presence of corporate headquarters do not seem to crowd out government grants to local charities.  相似文献

A mail survey was conducted to empirically investigate contributions to charity as a method of stimulating responses to a mail survey. The research design included a control group and four experimental groups with the following treatments: a prepayment of $1.00 enclosed with the questionnaire (immediate personal reward), $1.00 promised upon return of the questionnaire with the respondent identified (delayed personal reward, no anonymity), $1.00 promised upon return of the questionnaire with no identification of the respondent (delayed personal reward, anonymity), and the promise of $1.00 contribution to a respondent-selected charity (delayed non-personal reward). The $1.00 prepayment yielded a statistically significant higher response rate than the $1.00 promised to charity or $1.00 promised upon return of the questionnaire. This study generally supports existing empirical foudnations of equity theory. An immediate personal reward yields a higher response rate than a delayed personal or non-personal reward.  相似文献

The key contribution of this paper is to critically analyse advances made since the introduction of hospitality as a higher education subject, to capture contemporary thinking, and to support the recognition of the intellectual benefits for hospitality management theory and practices of a curriculum informed from a social science-based studies perspective. The benefits of this inter-relationship are demonstrated through the inclusion of an illustration informed by historical means of enquiry, which applies hermeneutical analysis and interpretation of St. Benedict's Rule (c. 530 A.D.). This serves to tangibly demonstrate the academic rigour, value, and educational gains achievable through a symbiotic relationship between hospitality studies and hospitality management.  相似文献
