Loyalty programs often feature multiple rewards with different requirements; for instance, an airline offering a free domestic ticket for 10 K miles, and an international ticket for 20 K miles. This research focuses on the role of multi-level rewards as a segmentation and price discrimination mechanism: Multi-level rewards can increase firm profits when buyers differ in purchase frequency and/or time discount factor. We propose that a program with two rewards can be designed in such a way that (i) it is more profitable than a one-reward program, and (ii) buyers self-select. Light users prefer to receive the smaller reward two times over receiving the larger reward one time, even though the smaller reward is less than half of the larger reward. We show that the smaller reward helps the firm enlarge its base in the light user segment. We also compare multi-level programs with quantity discounts.  相似文献

A three-stage Delphi study was conducted with experts and professionals working in the fields of disability and hospitality in order to identify some basic principles with respect to employment of people with disabilities (PWD). The potential effects of employing PWD on safety, cost, efficiency, service quality and management were investigated. Potentials and limitations of people with different types and degrees of disabilities with regard to jobs in the hospitality industry were also questioned. A notable guiding principle emanating from this study is that hiring of employees should be based on merit, suitability and capability of the candidate, regardless of the presence or degree of disability. Another important outcome is that the job or task appointed to PWD should not deteriorate the disability. A common guideline expressed by the participants was that jobs which critically require a certain sense or ability are not suitable for PWD who do not possess this sense or ability even with the aid of technology or by other means. However, apart from such extreme and obvious cases, experts mostly agree that PWD can fulfill any task in the hospitality industry as long as their professional knowledge and skills fit those tasks.  相似文献

This paper address the extent of capital mobility and foreign debt sustainability in Turkey over the 1962–2003 period by examining the relationship between saving and investment, and imports and exports, respectively. The empirical investment is based on cointegration, error correction models, and threshold and momentum threshold autoregressive models. Our findings are consistent with the existence of capital mobility and the ‘Strong’ form of foreign debt sustainability.  相似文献

During the socialist era, economists in the Balkan countries rarely published their work in the West due to political restrictions, methodological differences with the West, and inadequacy in Western languages. After the collapse of socialism, political barriers were lifted, a Western style of education in economics was adopted, and English began to be taught widely as the common language in the academic realm. The aim of this study is to discuss the impact of these policies on the publication performance of economists in the former socialist countries of the Balkans region. The results reveal that the number of international publications increased gradually over the post-socialist period and fast-reforming countries performed better than the slow movers.  相似文献

In the economic growth literature, the contribution of tourism to economic development has attracted great attention due to its significant roles as a source of foreign exchange earnings, creation of employment opportunities and an important source of public revenues in many countries. In this paper, we aim to analyse the empirical relationship between economic growth and tourism by employing different econometric techniques. First, we employed the Bound test approach developed by Pesaran, Shin, and Smith (2001, Bounds testing approaches to the analysis of level relationships. Journal of Applied Econometrics, 16(3), 289–326) in order to investigate the co-integration relationship between economic growth and tourism. Second, we used the Granger causality analysis for the 1998–2011 period and found evidence of a long-run uni-directional causality running from tourism to economic growth, but not vice versa. Our findings show that the Turkish case supports the tourism-led growth hypothesis (TLGH). Third, the autoregressive-distributed lag approach was employed in order to investigate the long-term and short-term static relationship between tourism and economic growth. The results show that tourism has a positive effect on gross domestic product and economic growth both in the long-term and short-term. Finally, the effect of tourism on economic growth was also investigated dynamically by employing the Kalman filter method. The findings of this method support the TLGH for Turkey.  相似文献

Ongoing regulatory reforms have led to several novel spectrum sharing models under the general umbrella of dynamic spectrum sharing. The private commons model introduced by FCC in 2004 allows spectrum licensees to provide secondary access to spectrum on an opportunistic basis while retaining ownership. Since wireless communication systems are typically overprovisioned in order to deliver service-level guarantees to (primary) users under short-term load variations, this model bears significant potential by facilitating utilization of temporal and spatial surplus of capacity through serving secondary users at possibly different service levels. A potential barrier to adoption of the private commons model is the uncertainty about secondary price–demand relationship which is difficult to predict in an emerging market: A selected price for secondary access may be profitable for some values of secondary demand but not for others, leading to a profound uncertainty about ultimate benefit of spectrum sharing. This paper aims to eliminate such an uncertainty by devising concrete guidelines and methods for profitability. The paper establishes that the price of secondary spectrum access can be chosen to guarantee profitability for any value of secondary demand: It is shown that for both the coordinated and uncoordinated commons regimes a profitable price should exceed a threshold value, which can be calculated. Hence profitability of private commons is insensitive to the demand function. This observation has two complementary interpretations: From a business perspective it provides a constructive approach to profitability; and from a regulatory perspective it provides reassurance that private commons is a healthy model. The paper also leverages the insensitivity property and outlines a technique to further enhance revenue via iterative spectrum offerings.  相似文献

The aim of this study was to examine the relationship between burn-out and psychological resiliency levels of special education teachers based on some demographic variables. 70 special education teachers working at 7 special education schools affiliated to North Cyprus Ministry of Education Primary Education Management Office and 21 schools which has special education mainstreaming room participated in this research. The Maslach Burn-Out Scale was used in this study to determine burn-out levels of special education teachers while the Psychological Resiliency Scale for Adults was used to determine their psychological resiliency levels. The study revealed a negative relationship between family cohesion (a sub-dimension of psychological resiliency) and emotional burn-out and desensitization (the sub-dimensions of burn-out), and it found no significant difference for gender in terms of both variables. The emotional burn-out score (a sub-dimension of burn-out scale) differed significantly based on the daily working hours of teachers. There is however a significant difference between “structural style” scores (the sub-dimension of psychological resiliency) based on educational status, as well as between desensitization scores of special education teachers and age.

ABSTRACT

Economists’ solution to the tragedy of the commons relies on well-defined property rights and competitive market mechanism for limiting individuals’ self-serving, short-sighted actions that result in a dramatic depletion of the common resources. However, this solution implicates a serious threat in terms of sustainability. Recently, deterioration of genetic diversity reached alarming levels, mainly attributed to escalating economic pressure that obliges farmers to shift from local breeds towards more profitable and more productive industrial breeds. This study empirically examines the efficiency of the free market mechanism as a solution to the tragedy of the commons through a unique natural experiment in which a huge demand shock arises regarding sheep. Results robustly show that the free market mechanism can cope with even a very challenging demand shock through the adjustment of prices without any shortage of the commodity. However, this finding does not guarantee that such an outcome is sustainable over the very long term. Analysis of the growth rate of the local sheep breeds population and cross-breed sheep population shows that the trend is overwhelmingly in favour of cross-breeds, thus supporting concerns for a free market mechanism, intrinsically driving the extinction of local sheep breeds, an invaluable genetic resource.  相似文献

This paper defines competitiveness as the ability of a country to increase its share of domestic and export markets, especially when they have a comparative advantage in a product and can produce at a lower opportunity cost. This paper briefly covers the theoretical information on this topic and provides empirical evidence of how domestic resource cost (DRC) can determine international competitiveness. A country is said to have a comparative advantage in the production of tradable goods if that country's production is efficient; if not, then it has a comparative disadvantage. The concept of comparative advantage has two meanings: The first definition states that efficiency of production is compared to two or more trading nations, and when the nations with the lowest opportunity costs are relatively more efficient, they have a comparative advantage. The other meaning of comparative advantage refers to the efficiency of different kinds of production within the domestic economy, which are compared in terms of earnings or savings of a unit of foreign exchange. Turkey seems to have a comparative advantage in plant products that do not exhibit economies of scale and are relatively labour-intensive, i.e. fruits and vegetables eliminating border and non-tariff barriers to trade in agriculture would allow both sides to exploit their comparative advantages better.  相似文献
