上海会展旅游发展模式探析

上海会展旅游目前还存在诸多制约自身发展的问题,主要表现在政府职能定位不清晰,旅游企业与会展企业的结合度不够,软件提升滞后等方面。德国是世界第一的贸易会展强国,德国会展旅游的发展经验不仅具有代表性,而且对上海有较强的借鉴意义。在分析问题和借鉴经验的基础上,本文认为上海会展旅游的发展模式应该具备以下一些特征:政府主导的职能、发挥行业协会作用、组建会展旅游企业集团、开展联合营销等。

Strategic transmission of information and short-term commitment

Summary. We examine the strategic role of information transmission in a repeated principal-agent relationship where the agent produces information that is useful to the principal. The agent values continuous employment for the principal because he makes a relationship-specific investment that can yield rents to him when the relationship is renewed. Assuming that the parties are sufficiently impatient, we show that full disclosure of the information produced occurs early in the relationship when the principal can commit to a long-term relationship, when the agent observes his valuation of continuous employment after making a report on information produced, or when the agent obtains a low valuation of continuous employment before making a report. By contrast, a strategic delay in the transmission of information occurs when the principal can only commit to a short-term relationship and the agent obtains a high valuation of continuous employment before making a report.

Risk identification in product innovation projects: new perspectives and lessons learned

The paper addresses the improvement of innovation project (IP) risk identification by applying the RBS (Risk Breakdown Structure) method, and represents a follow-up analysis of the subject (a case of IP before and after applying the method). The activities of risk identification are an initial phase in most of risk management processes and classifications. High-level risk-taking is one of the key characteristics of IPs, due to the fact that this type of projects is related to implementation of new ideas. An example illustrates the combination of RBS/WBS for evaluating the risk concentration, called Risk Breakdown Matrix. This research has proven that implementation of the presented approach in the context of the Serbian market can improve efficiency of all phases of the project, especially those related to planning phase.     

Contract enforcement and the size of the informal economy

This paper describes a model where the size of the informal sector decreases as the degree to which financing contracts can be enforced in the formal sector rises. Agents who choose to operate in the informal sector can evade taxes, but they have no access to official means of contract enforcement. Numerical simulations of the model suggest that lax tax enforcement alone does not suffice to generate a large informal sector. Contractual imperfections, on the other hand, can generate a large informal sector and account for several distinguishing features of the organization of production in developing economies.

Winner-take-all price competition

Summary. We analyze an oligopoly model of homogeneous product price competition that allows for discontinuities in demand and/or costs. Conditions under which only zero profit equilibrium outcomes obtain in such settings are provided. We then illustrate through a series of examples that the conditions provided are “tight” in the sense that their relaxation leads to positive profit outcomes.
