Pressure sores have plagued the nursing profession for many years as a major health care problem in terms of a patient's suffering and financial cost. Pressure sores are increasingly common in hospitalized patients in the United States with a 63% increase from 1993 to 2003. The nurse leader is accountable for the occurrence of pressure sores, a nurse-sensitive indicator, by a scorecard which is benchmarked against other facilities. The nurse leader must take a systematic approach in the prevention of pressure sores, with the strategy being consistent and motivating to the staff in order to improve patient outcome. The chief nursing officer, the unit manager, and the bedside nurse must all collaborate to prevent tissue injury in patients at risk for developing pressure sores and to promote wound healing in patients with existing breakdown. 相似文献

In labour markets with collective wage bargaining higher progressivity of the labour income tax creates a trade-off. On the one hand, wages are lowered and unemployment decreases, on the other hand, the individual labour supply decision is distorted at the hours-of-work margin. The optimal level of tax progressivity within this trade-off is determined using a numerical general equilibrium model with imperfect competition on the goods market, collective wage bargaining and a labour-supply module calibrated to empirically plausible elasticity values. The model is calibrated to macroeconomic and institutional parameters of both the OECD average and a number of individual OECD countries. In most cases the optimal degree of tax progressivity is below the actual level. A decomposition approach shows that the optimal level is increased by high unemployment and by the general tax level. 相似文献

This article examines the long-run money demand function for 11 OECD countries from 1983Q1 to 2006Q4 using panel data. The distinction between common factors and idiosyncratic components using principal component analysis allows for the detection of cross-member cointegration and the determination as to whether national or international sources are responsible for the non-stationarity of money and its determinants. Indeed, the finding that the common factors are I(1) while the idiosyncratic components are I(0) indicates that cross-member cointegration may exist and non-stationarity in the variables is primarily driven by common international trends. Furthermore, it is found that the impact of income on money demand is positive, whereas it is negative for the interest rate, exchange rate and stock prices. Except for the income elasticity of money demand, all estimated long-run coefficients are larger for the common factors of the variables than for the variables themselves. This article provides evidence that the exchange rate is an important determinant of money demand, whereas the results for the stock prices are ambiguous. Finally, the results of a panel-based error-correction model suggest that several domestic money stocks converge to a common international equilibrium relationship between the common factors. 相似文献

This article reports results from two experiments that investigate possible incidence of discrimination against people with foreign backgrounds in Sweden. In the first experiment, participants played the trust game and the dictator game with co-players of different ethnic affiliation. The family name of the players was exposed to their co-players. Results for the trust game showed no significant discrimination against co-players with foreign backgrounds. On the other hand, the results for the dictator game showed a statistically significant discriminatory behaviour by men against co-players with non-European backgrounds. The discriminatory behaviour was solely a male phenomenon. In the second experiment, the dictator game was replicated to check the stability of the results in the first experiment. The second experiment also examined whether people with foreign backgrounds discriminate against other people with foreign backgrounds; that is, the purpose was to discover whether discrimination is systematic. The observations in the second experiment underlined the results found in the first experiment: foreign co-players are discriminated against by Swedish players. However, we did not find that people with foreign backgrounds discriminated against other people with foreign backgrounds. 相似文献

Against the background of the current (economic) research which concentrates particularly on individual and structural factors, this paper examines if and to what extent social norms (in terms of attitudes towards gender roles and work commitment) can make a complementary statement in explaining women’s employment status and number of working hours. The impact is presumed to be enhanced through norms shared by people belonging to the same households, peer groups, and by residents of the same region. The analysis relies on a rich German dataset and employs a probit model with sample selection. The results highlight, among other things, the importance of the ‘relevant others’ (particularly partners living in the same household and peers sharing similar social and work characteristics, but not necessarily geographical proximity) in explaining women’s employment status. 相似文献

We quantify the magnitude of market segmentation in US consumer market and explore the underlying factors behind this segmentation, using a quarterly panel of retail prices for 45 products in 48 US cities from 1985 to 2009. The extent of market segmentation is estimated using city‐pair price differences within the framework of both linear autoregressive (AR) and nonlinear threshold autoregressive (TAR) models. We find that the magnitude of market segmentation varies from one product to another, but even more across city pairs in each product. Contrary to a widespread perception, market segmentation within the US is not necessarily larger for non‐tradable services compared to tradable goods. We identify potential drivers of market segmentation by relating the cross‐city and cross‐product variations of market segmentation to location‐specific and product‐specific characteristics—distance, relative city sizes, differences in wage and rent, type of product and proximity to marketplace. Distance, which captures more than transport costs, turns out to be the most salient factor even after controlling for a range of other potential factors. The effect of distance, however, varies substantially across products, with perishable products and locally produced products showing larger distance effect on market segmentation. We find that the magnitude of market segmentation has been somewhat stable during the sample period, but intercity price differences have become more sensitive to distance over time in many products under study. 相似文献

We investigate the link between fiscal policy shocks and asset markets. Our results show that spending shocks have: a positive and persistent effect on GDP in the U.S. and in the U.K., while for Germany and Italy, such impact is temporary; a positive and persistent effect on housing prices; a negative effect on stock prices; and mixed effects on the price level. A VAR counter-factual exercise suggests that fiscal shocks play a minor role in the asset markets of the U.S. and Germany, and substantially increase the variability of housing and stock prices in the U.K., while government revenue shocks have increased volatility in Italy. 相似文献

This paper analyses the relationship between politics and performativity of economics in the emergence of markets for biodiversity offsets. While the role of economics in constructing markets has been demonstrated by sociology and social studies of science, it has also become apparent that politics plays an important role in the material outcome of economic experiments. Two case studies of the creation of markets for biodiversity offsets are analysed, in the United States and England. The findings suggest that the creation of both markets is rooted in the language, concepts and models of economics. Politics, on the other hand, functions as a mediator of the material expression of those models. Through this mediation effect, similar economic models are performed differently, resulting in a variety of markets. This suggests that the material outcomes of processes of market creation are not defined at the outset, but can be influenced by political processes. 相似文献

Management of university–industry research collaboration (hereafter UIC) is the key to its success. In this respect, government can play an essential role in UIC. A public subsidy for research and development (hereafter R&D) is not only an important financial support for UIC but may also serve as a useful means of promoting trust among UIC members, resulting in higher innovation performance. However, few empirical studies have investigated the role a public R&D subsidy plays in promoting trust in UIC. To this end, by using original survey data, this study examines empirically whether a public R&D subsidy for UIC contributes to trust formation and, thus, to higher innovation performance based on trust. Our findings suggest that a public R&D subsidy promotes trust formation, which then increases the innovation performance of UIC participants, partially mediating the more direct effects of R&D subsidy on innovation performance. 相似文献

This paper estimates, using a large panel data set from rural Bangladesh, the effects of health shocks on household consumption and how access to microcredit affects households’ response to such shocks. Households appear to be fairly well insured against health shocks. Our results suggest that households sell livestock in response to health shocks and short term insurance is therefore attained at a significant long term cost. However microcredit has a significant mitigating effect. Households that have access to microcredit do not need to sell livestock in order to insure consumption. Microcredit organizations and microcredit therefore have an insurance role to play, an aspect that has not been analyzed previously. 相似文献

China's economic reforms have brought rapid growth in rural off-farm employment, raising questions about the assumption that rural China is labor surplus and has poorly functioning factor markets. We investigate this by testing for separability between household labor demand and supply using panel data. We find that separability is rejected overall, indicating that factor markets remain underdeveloped. Nonseparability, however, is associated with labor surplus in some areas and labor shortage in others. Moreover, separability holds where substantial employment opportunities exist in the wider township, suggesting that such employment promotes competitive allocation within villages as well as the inter-village movement of resources. 相似文献

Worker perceptions of job-related health risk are a little-studied dimension of heterogeneity in the labour market. According
to information from the European Working Conditions Survey (EWCS), one out of three European workers considers that her health
and safety is at risk because of work. Not surprisingly, risk perceptions are influenced by objective risk factors such as
hazardous working conditions, onerous job characteristics and by the probability to be affected by occupational accidents
and illnesses. This paper explores also the role played by personal characteristics and household structure for the explanation
of risk perceptions. After controlling for job characteristics, workplace hazards, job satisfaction and health outcomes, I
find that risk perceptions are strongly correlated with gender, age, and household structure. Lone parents as well as older
and more experienced workers have a higher propensity than other categories to consider their health at risk because of work.
The same seems to hold true for better educated workers, especially for those who have completed tertiary education. Further
results suggest that the relationship between household structure and risk perception is stable across gender. 相似文献

This study explores the relationship between the operating performance and corporate governance of bank holding companies (BHCs) in the U.S. The modified data envelopment analysis (DEA) is utilized to integrate the five rating indicators of CAMEL (Capital Adequacy, Asset Quality, Management, Earnings, and Liquidity) so as to estimate the BHCs' performance. This study also employs the modified tiered DEA to categorize 68 BHCs into three Tiers. Additionally, the truncated-regression is employed to discuss whether or not the corporate governance would affect the performance of BHCs. The empirical results present the trade-off relationship with CAMEL indicators in the Tier1—Efficient BHCs. Moreover, it has been found that there are negative impacts on BHC's performance from board size, outside directors, the average age of directors and CEO/Chairman duality, while there are positive impacts from the number of committee and Big-4 auditors. The results further prove that corporate governance is important for the operating performance of BHCs. 相似文献

Forecasting volatility is fundamental to forecasting parametric models of value-at-risk. The exponentially weighted moving average (EWMA) volatility model is the recommended model for forecasting volatility by the Riskmetrics group. For monthly data, the lambda parameter of the EWMA model is recommended to be set to 0.97. In this study, we empirically investigate if this is the optimal value of lambda in terms of forecasting volatility. Employing monthly realized volatility as the benchmark for testing the value of lambda, it is found that a value of lambda of 0.97 is far from optimal. The tests are robust to a variety of test statistics. It is further found that the optimal value of lambda is time varying and should be based upon recent historical data. The article offers a practical method to increase the reliability and accuracy of value-at-risk forecasts that can be easily implemented within an Excel spreadsheet. 相似文献

We test the Granger causal relations between speculation and returns in Chinese commodity markets using quantile regression method. We find that speculation Granger causes returns in rebar, bean pulp and rapeseed oil markets. At lower quantiles, estimates are negative; but estimates are positive at upper quantiles. This indicates that larger speculation results in larger return volatility. 相似文献

Regular payments or contributions to states’ exchequer funds are mandated for state level public sector enterprises (SLPEs) in most states in India. However, in the absence of a regular mechanism to ensure timely payments, the contributions are abysmally poor. In most SLPEs, the situation is driven by the presence of soft budget constraints and strong financial support from the state governments. The current study analyses the effect of political factors on the contribution that SLPEs make to the state governments’ exchequer funds. Using different econometric methods, the study finds that SLPEs located in assembly constituencies that are politically aligned with the state government, make frequent and larger contributions to the exchequer funds. Surprisingly, the subsidies provided to the SLPEs by state governments are not driven by political alignment between the state government and the constituency where the enterprise is located. In fact, subsidies compensate for the contributions to the extent that there is no effect of political alignment on net contributions (contributions–subsidies) by SLPEs to state governments. Finally, political alignment has a strong influence on the relative share of contributions made by SLPEs to state governments vis-à-vis the centre. These results are robust across different model specifications. 相似文献

At least in its early stages, health care reform is not likely to signal the end of concerns about retiree health benefits. Employers may want to explore prefunding as a practical approach to the problem. 相似文献
