We use a Hotelling-type model of two hospitals, one for-profit (FP) and the other not-for-profit (NFP) using quality to compete for patients. In an equilibrium that constrains the NFP to zero profits, the NFP share of the market decreases as fixed costs or patient’s marginal utility of quality increase, or as transportation and marginal quality costs decrease, conditions that make quality a more effective tool for attracting patients, improving the ability of the FP to compete for market share. We show that an NFP hospital cannot take the entire market without significant fundraising ability. The market shares predicted by our model are consistent with what is presently observed in Europe and the US. 相似文献

The risk of leakage poses a grave threat to natural gas pipeline safety. The high compressibility of gases combined with unsteady boundary conditions makes detecting leaks in pipelines a challenging endeavor. To date, in the literature, only a limited number of studies have focused on leak detection and diagnostics in gas mixture pipelines. The present study provides a system for detecting, locating, and estimating the size of small gas leaks from a compressible and dynamic natural gas flow in pipelines with improved accuracy. As a case study, a long natural gas pipeline of 80 km is simulated with leak sizes of 0%, 2%, and 5%. The safety system is developed using mass flow rate, temperature, and pressure measurements. Six classes for faulty cases and one class for no fault case were considered for the study. A shallow neural network classifier (SNNC) is trained to identify a specific fault class. The SNNC is based on a two-layered network with 20 and 7 neurons. An input vector of 15 variables is provided to the system, and the output is one of the seven possible classes. Leakage as low as 2% at various locations are correctly diagnosed with more than 99% correct classification rate. 相似文献
This study examines the clash between diversity policies as designed in the West and the challenges in implementing these in the Middle East and North Africa region. We contribute to the role of context in diversity management by studying how HR managers deal with diversity policies when the Western approach and the local context are perceived as being incompatible. Twenty HR/diversity managers working for multinational companies in nine different countries in the Middle East and North Africa region were interviewed. The findings show that a manager's understanding of the interrelated nature of multilevel factors of the local context influences the strategies adopted. Three strategies to deal with the perceived clash are identified: forcing a Western approach upon the local country, a reframing strategy where existing policies are reformulated to fit the Western requirements, and a sensitive approach in which the local context is considered. The study suggests that multinationa.l companies have to adapt diversity policies to local multilevel factors of the country in which they operate. 相似文献
Bangladesh is the 8th largest remittance recipient country in the world and one of the heavily dependent (11 % of GDP) countries of remittances. Despite its importance in policy making in developing countries like Bangladesh, there is absence of any study regarding the effect of remittances on the level of investment. In an attempt to fill the gap, we examine the cointegrating property and stability of the relationship among these variables using the ARDL bounds testing approach combined with CUSUM and CUSUMSQ tests. Our findings show that both remittances and trade openness positively and significantly influence the level of investment in Bangladesh, meaning that contrary to most conclusions found in the literature, migrant remittances in developing countries are not entirely spent in basic consumption needs. We also find that foreign aid has very little and insignificant impact on investment. Finally, we find long-run unidirectional causal relationship running from remittances to investment indicating that favorable policies to increase the flow of remittance will promote investment in Bangladesh. 相似文献
This study assesses the impact of the Great Recession (2008–2014) on the process of integration of the Eurozone labour markets. Through an agglomerative hierarchical cluster analysis using several European labour market harmonized indicators, we find that the crisis led to a greater integration, and to a polarization within the area. In the aftermath of crisis, two groups of countries clearly emerged, consisting Austria, Belgium, Finland, France, Germany, Italy, Luxembourg and Netherlands in the core while Greece, Ireland, Portugal and Spain in the periphery. 相似文献
This paper aims to examine short- and long-run asymmetries in the impacts of disaggregated oil price shocks on economic policy uncertainty, stock market uncertainty, treasury rates, and investor (bullish and bearish) sentiment in the US. To this end, we use a nonlinear auto-regressive distributed lag cointegration approach, which allows us to capture both positive and negative disaggregated oil shocks. We find that oil demand shocks are the main drivers of both measures of uncertainty, while oil supply shocks affect treasury rates. However, both oil demand shocks and oil supply shocks affect investor sentiment, with certain differences in the effects of positive and negative shocks. The overall effects of both oil demand and supply shocks—whether positive or negative—are stronger in the long-run than in the short-run. Additionally, we apply rolling causality and reveal evidence of a rather homogenous causal flow from disaggregated oil shocks to the variables studied, particularly around global stress periods. Our findings have implications for asset pricing and portfolio risk management and suggest policy formulations that differentiate between disaggregated positive and negative oil price shocks.
