Comparing variations in labor costs for two vs. one full-time nurse manager

Labor costs for two versus one full-time nurse manager were compared. Results revealed reductions in nursing costs per patient day. These results suggest that innovative models may hold promise as organizations struggle to retain nurses and decrease costs.     

Gender Effects of Social Security Reform in Chile

In 1981 Chile replaced a mature government-run social securitysystem that operated on a pay-as-you-go basis with a privatelymanaged system based on individual retirement accounts. Thenew system is more fiscally sustainable because pension benefitsare defined by contributions. The minimum pension guaranteedto beneficiaries with at least 20 years is funded from generaltaxes, preserving the tight matching between contributions andbenefits. The new system also eliminates several cross-subsidies.Men and women with less than secondary education gain underthe new system, but single women with more education lose. Comparisonof the old and the new systems reveals a complex set of factorsthat cause gender effects given constant behavior or changebehavior across genders.

现代化的生产活动中,技术更新占据着非常重要的地位,利用最新设备和技术去更新现有的陈旧设备和技术是工矿企业不断提高生产效率的必经途径;但是,对于只是短期使用或者本身将面临重大革新的设备和技术,在引进时就需要在租赁与购买之间做出决策.在这个过程中最难以解决的一个问题就是:如何准确地比较租赁成本与购买成本,以及选择其中成本较少、收益较大的方案.利用技术经济学中的设备经济理论,并将其与企业实际情况相结合,就可以提供一种很好的解决方法.     

Block Share Purchases and Corporate Performance

This paper investigates the causes and consequences of activist block share purchases in the 1980s. We find that activist investors were most likely to purchase large blocks of shares in highly diversified firms with poor profitability. Activists were not less likely to purchase blocks in firms with shark repellents and employee stock ownership plans. Activist block purchases were followed by increases in asset divestitures, decreases in mergers and acquisitions, and abnormal share price appreciation. Industry-adjusted operating profitability also rose. This evidence supports the view that the market for partial corporate control plays an important role in limiting agency costs in U.S. corporations.     

Best–Worst Scaling Approach to Predict Customer Choice for 3PL Services

This study describes a simple, theoretically based methodology to analyze the nature of customer demand for third‐party logistics provider service components. The method overcomes limitations in prior studies and enables us to examine the relative importance of product and service attributes as they pertain to the choice of third‐party logistics providers. Two distinct types of customers populate our data: those professing operational attributes and those seeking relational attributes. The theoretical and practical implications are that improved supply chain models can be developed when separate demand structures are taken into account.     

Market Orientation in the Transition Economies of Central Europe:: Tests of the Narver and Slater Market Orientation Scales

The Narver and Slater (Narver, J.C., and Slater, S.F.: The Effect of Marketing Orientation on Business Profitability. Journal of Marketing 54 (1990): 20–35.) market orientation scale is tested in the context of the transition economies of central Europe and found to be both valid and reliable. Relationships between market orientation and both marketing strategy and performance broadly follow predictions from the Western literature indicating that the adoption of a market orientation is equally applicable in transition as in Western economies. A number of different approaches, however, are evident in the transition economies suggesting that other business orientations may coexist with a market orientation creating a richer and more complex set or organizational drivers.     

Escalating penalties for repeat offenders: a note on the role of information

The severity of the sanction for a given offense is often determined by the offense history of the offender. We establish that this policy can be welfare-maximizing if individuals are imperfectly informed about the magnitude of the sanction. Imperfect information distorts individuals’ perception of the expected sanction of the first offense. Once detected, individuals learn about the sanction applicable to their act, making this argument less relevant for consecutive offenses.      

A reduced form framework for modeling volatility of speculative prices based on realized variation measures

Building on realized variance and bipower variation measures constructed from high-frequency financial prices, we propose a simple reduced form framework for effectively incorporating intraday data into the modeling of daily return volatility. We decompose the total daily return variability into the continuous sample path variance, the variation arising from discontinuous jumps that occur during the trading day, as well as the overnight return variance. Our empirical results, based on long samples of high-frequency equity and bond futures returns, suggest that the dynamic dependencies in the daily continuous sample path variability are well described by an approximate long-memory HAR–GARCH model, while the overnight returns may be modeled by an augmented GARCH type structure. The dynamic dependencies in the non-parametrically identified significant jumps appear to be well described by the combination of an ACH model for the time-varying jump intensities coupled with a relatively simple log-linear structure for the jump sizes. Finally, we discuss how the resulting reduced form model structure for each of the three components may be used in the construction of out-of-sample forecasts for the total return volatility.
