Theory suggests that insurance policies should not cover purely cosmetic procedures. This paper attempts to explain empirical
variation in coverage of a purely cosmetic procedure. Health maintenance organizations (HMOs) are modeled in a Cournot competition
with two decisions—the number of policies and the limits placed on medical care utilization. Comparative statics for an individual
market suggest, first, that restrictiveness is positively associated with the number of HMOs. Second, restrictiveness is positively
associated with the predisposition to demand managed care products. Third, each effect is strengthened by increasing the other
parameter. Restriction of tattoo ablation, a purely cosmetic procedure, is examined empirically. The first and second predictions
are supported at low levels of predisposition and numbers of HMOs, while the third prediction is not supported.
The data were obtained under a grant from the Office of Technology Assessment (HMO Laser Procedure Coverage) and a University
of Michigan Rackham Pre-Doctoral Fellowship (InterStudy and County Business Patterns). 相似文献

This study examines to what extent prices diverge across China and how long it takes prices to converge following idiosyncratic shocks. We consider monthly data using disaggregated goods prices from 36 cities in China. Following [Imbs, J., Mumtaz, H., Ravn, M., and Rey, H., 2005. PPP strikes back: aggregation and the real exchange rate. Quarterly Journal of Economics 120, 1–44.], we use two estimation methods: a fixed effect method when considering goods individually and a mean group estimation specification for a panel including all goods simultaneously. The mean group method also accounts for dynamic heterogeneity across goods. Impulse response functions are obtained to calculate half-lives. With both methods, we find half-lives of only a few months or less, supporting the conjecture that convergence rates within a country are faster than rates estimated in an international context. However, the half-life reported here is still shorter than that for other studies using disaggregated intracountry data. Perhaps a lower degree of specialization and market differentiation in developing countries creates a greater potential for price convergence. 相似文献

The precautionary principle is an emerging norm of international environmental policy affirmed in many treaties and laws. The principle, congruent to the ideal of sustainable development, is a controversial future-focused planning and regulatory mechanism which mandates that to protect against threats of serious and irreversible damage, precaution should be exercised even before harm can be scientifically demonstrated. The intent of this paper is to provide a literature review of the precautionary principle, examine the fundamental concepts underlying the principle and present an introductory discussion regarding its applicability to the tourism industry. Time and again numerous direct and indirect impacts are produced by the tourism industry, yet the potential for integrating precaution into tourism planning has not been examined. The authors consider the critical elements of the principle (uncertainty, risk, costbenefit analysis and science) in relation to the tourism industry, and provide examples of reference to the principle in the policy documents of non-governmental tourism organisations. An adapted framework is proposed for incorporating the precautionary principle into better tourism-industry decision-making. The precautionary principle is predicated as a viable tourism development tool and planning mechanism that safeguards environmental and human health by anticipating and controlling for future impacts of tourism. 相似文献

Empirical evidence suggests that inflation determination is not purely forward-looking, but models of price setting have struggled to rationalize this finding without directly assuming backward-looking pricing rules for firms. This paper shows that intrinsic inflation persistence can be explained with no deviation from optimizing, forward-looking behaviour if prices that have remained fixed for longer are more likely to be changed than those set recently. A relationship between the probability of price adjustment and the duration of a price spell is shown to imply a simple “hybrid” Phillips curve including lagged and expected inflation, which is estimated using macroeconomic data. 相似文献

In this paper, we explore how a large organization, operating in a mature, asset-intensive industry, used the social system of a key supply chain to generate significant improvement in operating performance (e.g., inventory turnover ratio improved from 0.8 to 3.2 in 5?years). A case study approach was used to study a steel rail supply chain involving an Australian railway company as the focal company. This supply chain consisted of two other companies: a steel manufacturer and a bulk transporter. Multiple forms of data were collected and analyzed, including models and process maps of the supply chain, published and internal documents, Enterprise Resource Planning system reports, and in-depth interviews of 31 key personnel involved in the supply chain. We found that the organizations had invested heavily in formal systems, such as governance processes and information technology systems. However, it was the informal mechanisms across and within the social system which made the greatest contribution to the resulting improvements. This suggests that organizations may be able to achieve significant operating performance outcomes at far lower cost and in shorter time frames by working through the existing social systems instead of focusing excessively on formal governance and IT systems. 相似文献

The valorisation of cross-cultural understanding and promotion of an ethic of global citizenship are at the forefront of the recent development and proliferation of international ‘gap year’ travel programs and policies. Governments and industry alike promote gap year travel uncritically as a guaranteed pathway to the development of inclusive ideologies associated with global citizenship. In this paper we examine how the neoliberalist context in which gap year travel programs have proliferated does little to promote tolerance. We then consider the recent growth of ‘volunteer tourism’ as an alternative gap year youth travel experience and explore how the implied resistance to self-serving neoliberalist values that it engenders can become coopted by neoliberalism. 相似文献

Whereas new product development (NPD) speed and product innovativeness are two critical strategic determinants of firm performance, previous studies show inconclusive findings about their effects. Drawing on institutional and contingency perspectives, this study elucidates value appropriation issues in NPD and examines how the effects of NPD speed and technological radicalness are contingent on institutional frameworks and market conditions. Results from 244 high-tech companies in China show that dysfunctional competition enhances the effect of NPD speed, but legal inadequacy hinders the impact of technological radicalness on firm performance. Market growth strengthens the performance effect of NPD speed but restrains the effect of technological radicalness. In addition, technological radicalness demonstrates stronger effects on firm performance when demand uncertainty is high. 相似文献

Today's multichannel, multimedia retail marketing environment presents a number of brand management challenges. From a micro perspective, marketers must manage each individual channel and communication option to maximize their direct sales and brand equity effects, as well as any indirect brand equity effects from being associated with a particular channel or communication option. From a macro perspective, marketers must design and implement channel and communication options such that sales and brand equity effects are synergistic. Concepts, frameworks, and future research directions are put forth to address these different challenges. 相似文献

This paper introduces a form of boundedly-rational inflation expectations in the New Keynesian Phillips curve. The representative agent is assumed to behave as an econometrician, employing a time series model for inflation that allows for both permanent and temporary shocks. The near-unity coefficient on expected inflation in the Phillips curve causes the agent's perception of a unit root in inflation to become close to self-fulfilling. In a “consistent expectations equilibrium,” the value of the Kalman gain parameter in the agent's forecast rule is pinned down using the observed autocorrelation of inflation changes. The forecast errors observed by the agent are close to white noise, making it difficult for the agent to detect a misspecification of the forecast rule. I show that this simple model of inflation expectations can generate time-varying persistence and volatility that is broadly similar to that observed in long-run U.S. data. Model-based values for expected inflation track well with movements in survey-based measures of U.S. expected inflation. In numerical simulations, the model can generate pronounced low-frequency swings in the level of inflation that are driven solely by expectational feedback, not by changes in monetary policy. 相似文献

The relationship between job satisfaction levels and the remuneration of non-owner managers employed by a sample of 97 UK small and medium sized enterprises (SMEs) is investigated. The main empirical findings are that relative remuneration levels appear to be largely explained by differences in human capital and job/firm characteristics and that job satisfaction is positively related to deviations from these estimated comparison-income levels. Moreover, the equity theory expectation that individuals with the least prospect of redressing payment inequities will have the greatest incentives to respond to payment inequities by congitive adjustment is also supported. The results indicate that job satisfaction levels for individuals expecting to remain in their current post are not significantly affected by current payment inequities. For those managers who expect to move firms, the amount of payment inequity has a significantly positive effect upon their job satisfaction. 相似文献
