This article has formally identified distinct historical inflation regimes in Canada since 1961 in order to facilitate an investigation of the impact of regime changes on the wage-price dynamics in the economy. Both in and out-of-sample evidence suggest that wage growth exerts an influence on inflation only during a high-inflation regime but inflation exerts a more systematic and quantitatively stronger influence on wage growth regardless of the prevailing inflation regime. Overall, the results do not support either the ‘cost-push’ view of inflation or the ‘new view’ that claims that increased globalization during the 1990s has reduced the feedback from wage growth to inflation by weakening the bargaining power of workers. 相似文献

As the US population ages, more older adults will face transportation and mobility challenges. This study examines the characteristics and contributing circumstances of nonfatal older adult pedestrian injuries. Data were obtained from the National Electronic Injury Surveillance System-All Injury Programme (NEISS-AIP) for the years 2001 through 2006. Cases included persons aged 65 years and older who were nonfatally injured on a public roadway. The results indicated that on average, an estimated 52,482 older adults were treated in emergency departments each year for nonfatal pedestrian injuries. Falling and being hit by a motor vehicle were the leading mechanisms of injury, resulting in 77.5% and 15.0% of older adult pedestrian injuries, respectively. More than 9000 older pedestrian fall-related injuries each year involved a kerb. It is concluded that the growth in the older adult population could add to the overall burden of these nonfatal pedestrian injuries. Making transportation and mobility improvements, including environmental modifications, is important for preventing these injuries. 相似文献

Individual performance is a building block of organizational success. Not surprisingly, virtually all organizations have in place some type of performance management system. Yet, managers and employees are equally skeptical that performance management adds value; usually, it is seen as a waste of time and resources. We argue that the potential benefits of performance management are not realized because most systems focus exclusively on narrow and evaluative aspects such as performance appraisal. Herein, we offer a broader view of performance management, including discussion of how it differs from performance appraisal. We highlight specific and important benefits of performance management for employees, managers, and organizations. We also describe research-based conclusions regarding how performance management systems should be designed and implemented to realize these benefits. We hope our article will demonstrate that well-constructed performance management systems should not be hated, but rather embraced. 相似文献

An analysis of wheat yield series from ten localities in Victoria was undertaken to investigate for independence of observations and to test for normality of the distributions. The conclusion was reached that Victorian wheat yield series are composed of random observations and form frequency distributions which display slight negative skewness. The situation may be different for other crops or for wheat in other areas. 相似文献

We examine differences in information content between order submission sizes and trade sizes by U.S. equity traders. Increasing (decreasing) order submission (trade) size is reflective of information. The result suggests that better-informed traders want to trade in a large size, but that they engage in stealth trading practices or break larger orders into smaller sizes in order to conceal information. While prior studies tend to narrowly focus on trade executions at the market-centre level, our findings indicate that order submission size varies significantly from trade size and that both sizes are informative about future prices, albeit in an inverse manner. 相似文献

A bstract . This paper is an analysis of the demand for thoroughbred racetrack wagers, examining evidence that would support the existence of two types of bettors: the risk-averse informed bettor versus the uninformed bettor. Looking at 12 major racetracks over the fall of 2002, we undertake an empirical examination of the determinants of bettors' preferences for particular wagers on specific races. The goal is to try to determine what individual aspects of a race (conditions, surface, participants, etc.) will encourage increased wagering dollars. With the advent of simulcasting, the competition for the wagering dollar is fierce, as the bettor can choose from more than 100 races daily, each race offering numerous betting options. We find for most wagers that higher quality participants, larger and more competitive fields, and turf races increase betting volume while higher pari-mutuel takeout, poor track conditions, and other races run concurrently reduce volume. However, more competitive fields reduce betting volume in the show and trifecta pools. Optimal field size is determined to be between 10 and 12 betting interests. Overall, we find support for the existence of a significant share of risk-averse informed bettors. 相似文献
