A Generic Framework for Automated Multi-attribute Negotiation

Agents in a negotiation may have to negotiate multiple issues simultaneously. Automated multi-attribute negotiation provides an important mechanism for distributed decision makers to reach agreements on multiple issues. Moreover, it also furnishes the opportunity to reach “win–win” solutions. In this paper, we first provide a survey that synthesizes the research on multi-attribute negotiation. We discuss the limitations of the existing research and conclude that three key issues need further study: incomplete information, Pareto optimality, and tractability. We then present a generic framework for automated multi-attribute negotiation with two new mechanisms that address the above issues. Finally, we discuss the challenges and directions for future work.     

Service quality gaps of business customers in the shipping industry

This paper extends the gaps model of [Zeithaml, V.A., Parasuraman, A., Berry, L. 1990. Delivering Quality Service: Balancing Customer Perceptions and Expectation. The Free Press, New York] from the service provider to the business customer side by examining two service quality (SQ) gaps. One is the SQ gap between types of business customers and the other is the SQ gap among employee statuses of business customers. Besides that, the five-factor SERVQUAL measure as the initial hypothesized model is also tested. The applicability of SERVQUAL to measuring the perceived SQ of customers in the shipping industry of Taiwan is rejected empirically. The existence of the two hypothesized gaps is verified by the method of MANOVA.     

The incremental value of a futures hedge using realized volatility

A number of prior studies have developed a variety of multivariate volatility models to describe the joint distribution of spot and futures, and have applied the results to form the optimal futures hedge. In this study, the authors propose a new class of multivariate volatility models encompassing realized volatility (RV) estimates to estimate the risk‐minimizing hedge ratio, and compare the hedging performance of the proposed models with those generated by return‐based models. In an out‐of‐sample context with a daily rebalancing approach, based on an extensive set of statistical and economic performance measures, the empirical results show that improvement can be substantial when switching from daily to intraday. This essentially comes from the advantage that the intraday‐based RV potentially can provide more accurate daily covariance matrix estimates than RV utilizing daily prices. Finally, this study also analyzes the effect of hedge horizon on hedge ratio and hedging effectiveness for both the in‐sample and the out‐of‐sample data. © 2009 Wiley Periodicals, Inc.

治理型公司及其发展前景

传统的公司治理模式强调了权力制衡,目标是为了强化对公司内部人的控制和监督,而治理型公司模式则认为公司治理的核心不在干监督内部人而在于改善决策,目标是降低发生错误的可能性和加快纠正错误的速度。管理型公司反映了人性和组织行为的弱点,公司内部人的错误除非演变为灾难,否则不会得到纠正。在我国现有国情下,治理型公司的优势和前景非常明显,因此,它对我国公司治理改革具有重要的理论和现实意义。

Stickiness of Rental Rates and Developers’ Option Exercise Strategies

In this study we incorporate sticky rents into a real options model to rationalize the widely documented overbuilding puzzle in real estate markets. Given the assumption that developers’ objective function is to maximize total revenue by selecting an optimal occupancy level, our model provides a better explanation of the phenomena we observed in the real world than the traditional market-clearance based real options models. We also show that developers’ exercise strategies can be affected by the size and the type of property markets. In other words, developers’ exercise strategies could differ among markets and under different conditions. Submitted to Cambridge—Maastricht 2005 Symposium.     

Authority and communication in the laboratory

We report findings from experiments on two delegation–communication games. An uninformed principal chooses whether to fully delegate her decision-making authority to an informed agent or to retain the authority and communicate with the agent via cheap talk to obtain decision-relevant information. In the game in which the delegation outcome is payoff-dominated by both the truthful and the babbling communication outcomes, we find that principal-subjects almost always retain their authority and agent-subjects communicate truthfully. Significantly more choices of delegation than of communication are observed in another game in which the delegation outcome payoff-dominates the unique babbling communication outcome; yet there is a non-negligible fraction of principal-subjects who holds on to their authority and agent-subjects who transmits some information. A level-k analysis of the game indicates that a principal-subject “under-delegates” due to the belief that her less-than-fully-strategic opponent will provide information; such belief is in turn consistent with the actual play.     

The role of domestic demand in the economic growth of Malaysia: a cointegration analysis

For the past four decades (1961-2000), the Malaysian economy grew at an impressive average rate of 6.8% per annum. The rapid growth has been attributed, in part, to the tremendous success in the export-oriented industrialization policy. Several empirical studies on export-led growth for Malaysia have, however, led to inconclusive and mixed results. This may be due to the exclusion of domestic demand in the bivariate or multivariate models used in the studies. This study re-examines the role of domestic demand in economic growth in Malaysia. Using a three-variable cointegration analysis, the study shows that there exist short run bilateral causalities among the three variables, which implies that both the export-led growth and domestic demand-generated growth hypotheses are at least valid in the short run. On the other hand, the results are not supportive of the export-led growth hypothesis in the long run. Instead, the highly significant positive impact of domestic expenditure on economic growth implies that use of domestic demand as the catalyst for growth is appropriate.     

全面减免东盟关税对中国宏观经济和产业影响的可计算一般均衡分析

Chingem模型是一个中国静态CGE模型.本文在Chingem模型的基础上,分析了2010年中国全面减免东盟原六国关税对中国宏观经济和产业的长期影响.在原模型的基础上,改进了宏观闭合条件.将原来作为剩余量处理的居民消费与居民收入联系起来,使经济增长会作用到居民消费,使模拟结果更加符合实际.研究表明全面减免对东盟的关税有利于我国经济的和谐发展;减少了经济增长对净出口的依赖;促进了进、出口商品结构的升级;促进了服务业的发展,但农业和制造业的一些部门会受到负面影响;制造业的就业会下降,服务业和农业的就业会上升.     

地方政府利益、地方政府行为与经济增长

目前,对中国地方政府的经济行为的研究强调了在经济转型过程中地方政府在多样化的地方经济发展模式中的主导作用,注意到了地方政府目标的多重性,本地区社会福利最大化,政府利益最大化以及中央政府的满意程度等。对地方政府在公共产品的提供、就业、收入分配、实现社会公平等方面行为不到位方面的研究是从定性方法来论证。本文试图在定性分析基础上建立一些基本的数学模型为将来的计量研究提供一个模型框架。
