The sharing behavior among users and the rewarding strategy of firms are modeled. The optimal sharing bonus is worked out and the impact of social relationships among customers is discussed. The results show that the higher the bonus,the more efforts the inductor is willing to make to persuade the inductee into buying. In addition,the firms should take the social relationship into consideration when setting the optimal sharing bonus. If the social relationship is weak,there is no need to adopt the SRP. Otherwise,there are two ways to reward the inductors. Also,the stronger the social relationship,the fewer the sharing bonuses that should be offered to the inductors,and the higher the expected profits. As a result,it is reasonable for the firms to implement SRPs on the social media where users are familiar with each other.展开更多

According to Abraham Maslow, within every person is a hierarchy of five needs: physiological needs, safety needs, social needs, esteem needs, and self-actualization needs Organizations must be able to identify what employees desire to secure optimum performance and to meet the needs of both employees and employers. This research focuses on the generational gap and the significance of intrinsic and extrinsic rewards in the workforce. The purpose and objective of this research are to test the significance of monetary versus non-monetary rewards among the different generations in the organization. A self-designed questionnaire distributed to a multi-generational group of employees of selected organizations was used to collect the analyzed data. Sixty-five (65%) responses were obtained. Secondary data were used to elucidate the needs in this area of study. Because the workforce is predicted to become more diverse in terms of age, organizations will be unlikely to implement one set of rewards for the multiple generations. This is due to the differing expectations and requirements among the generations. However, the results indicate no significant difference in monetary versus non-monetary rewards among the different generations in the workforce.展开更多

What is the impact of competition on incentives to invest, and on capacities to invest? What is the role of the rate of penetration and technical progress? This paper highlights the fact that investment incentives are positively related to potential for technical progress. Investment incentives also depend on market structure, competition intensity, and penetration rate, but not monotonically. This paper consists of a theoretical part which, under assumptions of full market coverage and market share symmetry, shows that for each national market, there is a target level of investment which companies strive to achieve but had not exceeded, and an empirical part that confirms the findings of the theoretical part and explains the differences with the theoretical part by relaxing the assumptions of full coverage and market share symmetry. This target level on the one hand depends on the potential for technical progress and on the other hand, depends on the rate of penetration. From a social perspective, this target level is the best amount that companies are encouraged to invest. Non-achievement of the target level entails underinvestment and a decrease in consumer surplus and welfare and may slow down technical progress. A data set covering 30 countries over a period of eight years is used to empirically prove the existence of a change in investment behavior depending on whether or not the target level is achieved. A low margin per user may hamper achievement of the target level. As a result, maximum consumer surplus and welfare occur under imperfect competition but not under perfect competition.展开更多

Till now there is no academic consensus on which electricity market design provides the least distorting investment incentives. Alternative approaches that have been adopted around the world for ensuring the appropriate level of investment in electric generation capacity are discussed, and much attention is devoted on the evaluation of capacity payment systems. The finding is that on one hand, capacity payment systems have good effect on reducing spot market price volatility and increasing the volume of generating capacity at the costs of relatively high total electricity prices; on the other hand, however, they are not robust against either the abuse of market power in the energy market or being manipulated.展开更多

In the face of this there is a concomitant need to improve and repair transportation infrastructure. Construction frequently requires a reduction in capacity during construction activity; consequently road users as well as adjacent businesses must endure the delays and inconveniences associated with transportation construction. Recognizing the problems that construction can produce, state highway agencies (SHAs) have continually sought ways to minimize the negative impact from their construction operations. Incentive contracting has played an important role in this effort to improve project performance. The Florida Department of Transportation (FDOT) is one of the leading SHAs using such innovative contracting methods as Incentive/Disincentive (I/D), A+B (cost plus time bidding) combined with I/D, No Excuse Bonus, and Liquidated Savings. This paper analyzes the traffic impact on incentive project time performance using highway construction projects recently completed in Florida. Project data obtained from FDOT were evaluated using time performance indices. A survey of traffic impact on project work types was performed in Florida in order to evaluate the relationship between construction project types and road traffic influence during construction. Based on the survey results, the 38 most frequently used work types in Florida during the study period were categorized into three traffic impact levels: (1) high traffic impact, (2) medium traffic impact, and (3) low traffic impact. Statistical analysis was performed. The results show that there are significant differences on project time performance between low and high impact levels as well as low and medium impact levels.展开更多

The choice of particular scheme either financial or non financial and to what level it contributes to the productivity of employees remain at stake. Therefore, this study set to evaluate the level of awareness, impact and contribution of the schemes with more emphasis to the non financial incentive schemes. A questionnaire survey involving management and artisans of the three tiers of NCl (Nigerian Construction Industry): large, medium and small within Kaduna and Abuja Nigeria was conducted. Three hundred (300) responses from the management and artisans were used for analysis, inferences and conclusions. The survey result revealed that non-financial incentive schemes are mostly employed in the large and medium scale construction firms. Though, preference by medium and small scale firms was based on those that do not require fund to implement and maintain. It was concluded that, construction firms operating in Nigeria ought to strive more towards implementing non-financial incentive in their organization since artisans are willing to improve their output.展开更多

Ten years later, the same debate is being held all over again, just from a different point of view. It is emblematic of this current financial crisis because the banking system is much bigger than GDP (Gross Domestic Product). Setting aside the sluggish economic performance, as well as the usual gap between northern and southern regions, people are uncomfortable with the EU. Getting the EU to finance a deficit is very tempting because it seems to be a politically and socially painless option, but can we count on the EU to devise such a smoothly running system? Cyprus is interesting on many levels, from the debate concerning the limits of cohesion policy to the need of finding new solutions for the European periphery. It raises the question of whether a real fiscal and political union is possible, in light of the actual geoeconomic and geopolitical dynamics among the EU, Turkey, and Russia. The aim of this paper is to explore the possible mechanisms for an integration of Cyprus in order to go beyond fiscal burden sharing. It is an important starting point to paving the way to new policies and strategies for changing the objectives of economic convergence.展开更多

The system of commutation revocation can obey to the criminal policy of temper justice with mercy and the principle of "collecting mistakes whenever discovered" and obtain the penalty goal of special prevention. In order to protect some prisoner' s benefit, the prisoner who be revoked the rewards of commutation can take part in the course of juice, the postbox which be opened only by the NPC and committee must be installed in prison. This will be advantage of some prisoner who be revoked the rewards of commutation appealing to the NPC and committee. Because of weakness of necessarily and execution, the system of commutation revocation cannot be established when the prisoner have been released currently.展开更多
