If the payoff obtained by the parties of an agreement depends on the values set for variables the value of which cannot be described precisely or monitored accurately, then the first best outcome may not be achieved. It is shown here that in some cases a second best long term agreement gives the parties a higher payoff, in other cases a short term arrangement is preferred. The interpretation of this result given in the paper is that when a long term contract is preferable, then firms are unable to commit themselves to it through a collusive agreement, and they will try to merge. Vice versa, no need to integrate arises when the preferred second best agreement is the short term one. The last section provides an example, where advertisement effort is non-contractible, while prices are.  相似文献

A two period model of the training decision is analysed using a human capital approach. The segmented labour market model where training opportunities distinguish entrants is compared with a competitive structure with homogeneous entrants. The main conclusions in the paper are the clear effects of training wages and the different effects in the two market structures of both wages and employment prospects in the unskilled market on training.  相似文献

Great hopes have been placed in the sharing economy to provide a new business model based on peer-to-peer (P2P) exchanges of underutilized assets. As a model, the sharing economy has been expected to make significant contributions to sustainability, providing new opportunities for entrepreneurship, more sustainable use of resources, and consumer co-operation in tight economic networks. However, in recent years, digital platforms have turned into the most important actors in the global sharing economy, turning global corporations, such as AirBnB, Booking, or TripAdvisor into intermediaries controlling and profiting from most transactions. Focused on accommodation, this paper conceptualizes the sharing economy in comparison to the wider collaborative economy, and discusses its social, economic, environmental, and political impacts in comparison to the sustainable development goals. It concludes that the sharing economy has great potential to make very significant contributions to sustainability, though the model is increasingly being replaced by the collaborative economy, which performs as an extension and acceleration of neoliberal economic practices.  相似文献

This article presents a grounded theory to explain why some small businesses in tourism adopt sustainable business practices while others do not, even when they share environmental and wider sustainability concerns. It does so based on research undertaken among business owners in Crete. The paper starts by considering studies on sustainability awareness, knowledge and the mechanisms for accepting responsibility. Secondly, it summarises the influence of task difficulty and effort on sustainability self-efficacy. Thirdly, it focuses on social comparisons and vicarious experiences, as a way of learning what is important. Finally, it examines powerlessness due to perceived situational constraints. In so doing, the study finds that self-efficacy helps to explain sustainable attitude formation and the attitude-behaviour gap; it partly shifts the locus of responsibility for an inability to act sustainably away from the individual and towards their context. The paper contributes to the theoretical literature on small businesses and sustainability, and leads to new avenues for policy interventions.  相似文献

Before embarking on the development of rural areas or regions it seems necessary to answer the following key questions: what goals of the parties involved can be realized, and where, when and how? To tackle these questions we have developed a ‘roadmap’, as part of an overall sustainable development procedure for physical planning and spatial management in rural areas. The roadmap is a tool for the process manager and the people involved. It helps to find the way in the exploration of the potential social, economic and ecological benefits of developing the area or region. The purpose of using the roadmap is to alleviate doubts about the advantages of cooperating in pursuit of sustainable development. A back-casting approach is applied to create appealing visions of the future and visualize mutual opportunities worth implementing. In this article we first describe the need for this new roadmap. We then describe its use, step by step and in some detail. An example of the exploration process is described and the strengths and weaknesses of the roadmap are discussed.  相似文献

The purpose of this study is to identify generational differences and similarities among hospitality employees and managers in order to develop leadership strategies and management styles that can be utilized to increase employee morale and productivity while enhancing recruitment and retention rates of highly qualified workers. Data for this study were collected through a series of in-depth focus group discussions. Findings indicated significant generational differences in world views, attitudes toward authority and perspectives on work. Findings suggested the Baby Boomers respect authority and hierarchy, while the Generation X-ers (Gen X-ers) rebel against authority. Findings also suggested while Baby Boomers live to work, Gen X-ers work to live. The Baby Boomers are willing to wait their turn for promotions and rewards, and are very loyal. On the other hand, Gen X-ers expect immediate recognition through title, praise, promotion, and pay. They also want a life outside of work—they are not likely to sacrifice theirs for the company. The Millennial Generation believes in collective action, with optimism of the future, and trust in centralized authority. They like teamwork, showing a strong will to get things done with a great spirit.  相似文献

Global leaders agree on the need to substantially decarbonize the global economy by 2050. This paper compares potential costs associated with different policy pathways to achieve tourism sector emission reduction ambitions (?50% by 2035) and transform the sector to be part of the mid-century decarbonized economy (?70% by 2050). Investment in emissions abatement within the tourism sector, combined with strategic external carbon offsets, was found to be approximately 5% more cost effective over the period 2015–2050 than exclusive reliance on offsetting. The cost to achieve the ?50% target through abatement and strategic offsetting, while significant, represents less than 0.1% of the estimated global tourism economy in 2020 and 3.6% in 2050. Distributed equally among all tourists (international and domestic), the cost of a low-carbon tourism sector is estimated at US$11 per trip, equivalent to many current travel fees or taxes. Exclusive reliance on offsetting would expose the sector to extensive and continued carbon liability costs beyond mid-century and could be perceived as climate inaction, increasing reputational risks and the potential for less efficient regulatory interventions that could hinder sustainable tourism development. Effective tourism sector leadership is needed to develop a strategic tourism policy framework and emission measurement and reporting system.  相似文献
