This paper investigates an economy in which there are short-term wage contracts that are re-negotiated under certain conditions. The paper determines the optimal frequency of wage re-negotiation and shows that it depends positively on measures of aggregate variability and Phillips curve slope. The role of optimal wage re-negotiation is to mitigate the output effects of various shocks. In the context of an open economy, it is shown that the desirable exchange rate regime in an economy with optimal wage re-negotiation depends on the stochastic structure of the economy. 相似文献

The satisfaction of basic human needs in developing countries follows a nonlinear curve relative to per capita income, asymptotically approaching a limiting level. Within this general relationship, some countries are more ‘efficient’ than others in improving basic needs at lower per capita income levels. Infant mortality rates in 116 countries, from 1950 to 1980, are analyzed to identify factors affecting a country's efficiency in reaching infant mortality targets relative to its Gross Domestic Product per capita. The determinants of efficiency include export structure, internal distribution, late development and access to education. Implications for development policy are discussed. 相似文献

Food Insecurity and Hunger in the Kindergarten Classroom: Its Effect on Learning and Growth 总被引:1,自引:0,他引:1
This study investigates the correlation between food insecurity, educational achievement, and health among kindergarten children in the United States. Data from the Early Childhood Longitudinal Study—Kindergarten Cohort are used to analyze educational achievement and physical growth of kindergartners faced with food insecurity. The results demonstrate that children begin to experience the effects of food insecurity even at the most marginal level of household food deprivation. Children in households with any signs of food insecurity score lower and learn less during the school year. 相似文献

We study whether the sealing of a defendant’s judicial records during a patent lawsuit filing correlates with the defendant’s level of competition and disclosure. Courts permit sealing of judicial records when competitive damage outweighs the public interest in access to documents and records. We find that defendants with sealed judicial records have higher research and development (R&D), lower industry sales concentration, and more references to competition in their annual reports than defendants without sealed judicial records. We observe faster mean reversion of return on net operating assets when courts seal defendant records. The results suggest that sealing relates to archival measures of competition. Finally, consistent with proprietary costs restraining disclosure, we find that defendants with sealed judicial records are less likely to issue management forecasts, file 8-Ks less frequently, and have longer and less readable 10-Ks. 相似文献

There is ample justification for the consensus view that the Horizontal Merger Guidelines have proven one of antitrust law??s great successes in the grounding of antitrust doctrine within economic learning. The foundation of the Guidelines?? success has been its widespread adoption by federal courts, which have embraced its rigorous underlying economic logic and analytical approach to merger analysis under the Clayton Act. While some have suggested that the Guidelines?? most recent iteration might jeopardize this record of judicial adoption by downplaying the role of market definition and updating its unilateral effects analysis, we believe that these updates are generally beneficial and include long-overdue shifts away from antiquated structural presumptions in favor of analyzing competitive effects directly where possible. However, this article explores a different reason to be concerned that the 2010 Guidelines may not enjoy widespread judicial adoption: the 2010 Guidelines asymmetrically update economic insights underlying merger analysis. While the 2010 Guidelines?? updated economic thinking on market definition and unilateral effects will likely render the prima facie burden facing plaintiffs easier to satisfy in merger analysis moving forward, and thus have significant practical impact, the Guidelines do not correspondingly update efficiencies analysis, leaving it largely as it first appeared 13 years earlier. We discuss two well-qualified candidates for ??economic updates?? of efficiencies analysis under the Guidelines: (1) out-of-market efficiencies and (2) fixed-cost savings. We conclude with some thoughts about the implications of the asymmetric updates for judicial adoption of the 2010 Guidelines. 相似文献

Technical trading rules for nonlinear dynamics of stock returns: evidence from the G-7 stock markets
Kwang-il Choe Joshua Krausz Kiseok Nam 《Review of Quantitative Finance and Accounting》2011,36(3):323-353
This paper explores a possible link between an asymmetric dynamic process of stock returns and profitable technical trading rules. Using the G-7 stock market indexes, we show that the dynamic process of daily index returns is better characterized by nonlinearity arising from an asymmetric reverting property. The asymmetric reverting property of stock returns is exploitable in generating profitable buy and sells signals for technical trading strategies. The bootstrap analysis shows that not all nonlinearities generate profitable buy and sell signals, but rather only the nonlinearities generating a consistent asymmetrical pattern of return dynamics can be exploitable for the profitability of the trading rules. The significant positive (negative) returns from buy (sell) signals are a consequence of trading rules that exploit the asymmetric nonlinear dynamics of the stock returns that revolve around positive (negative) unconditional mean returns under prior positive (negative) return patterns. Our results corroborate the arguments for the usefulness of technical trading strategies in stock market investments. 相似文献
