‘Give me a chance!’ An experiment in social decision under risk

This paper reports the results of a ‘probabilistic dictator game’ experiment in which subjects were given an option to share chances to win a prize with a dummy player. Using a within-subject design we manipulated two aspects of the decision, the relative cost of sharing and the nature of the lottery: the draws were either independent for the two players (‘noncompetitive’ condition) or one’s success meant other’s failure (‘competitive’ condition). We also asked for decisions in a standard, non-probabilistic, setting. The main results can be summarized as follows: first, a substantial fraction of subjects do share chances to win, also in the competitive treatments, thus showing concern for the other player that cannot be explained by outcome-based models. Second, subjects share less in the competitive treatment than in other treatments, indicating that procedural fairness alone cannot explain the data. Overall, these results suggest that models aiming at generalizing social concerns to risky environments will have to rely on a mix of distributive and procedural fairness.

Value Frame Fusion in Cross Sector Interactions

Prior research flags the inherent incompatibilities between for-profit and nonprofit partners and cautions that clashing value creation logics and conflicting identities can stall social innovation in cross sector partnerships. Process narratives of successful versus unsuccessful cross sector partnerships paint a more optimistic picture, whereby the frequency, intensity, breadth, and depth of interactions may afford frame alignment despite partners’ divergent value creation approaches. However, little is known about how cross sector partners come to recognize and reconcile their divergent value creation frames in order to co-construct social value. Using longitudinal narratives of four dyads, we show that partners initially contrast their sector-embedded diagnostic frames and then work together to deliberately develop partnership-specific prognostic frames. We extend the literature on framing by developing a four-stage grounded model of frame negotiation, elasticity, plasticity, and fusion which unpacks the relational process of value creation in cross sector partnerships. Our qualitative analyses further show how partners orchestrate multilevel coordination that helps scaffold and calibrate this relational process of frame fusion.     

基于DEA模型的高技术产业R&D效率评价

作为创新的"孵化器",高技术产业的RD效率问题至关重要。从区域与行业交叉的视角出发,选取RD活动人员折合全时当量和RD经费内部支出作为投入指标,有效发明专利数和新产品销售收入作为产出指标,运用DEA模型研究了中国高技术产业5个行业在17个省市的RD活动效率,运用层次聚类分析对17个省市加以聚类。研究结果表明:中国高技术产业RD效率普遍偏低,没有任何一个省市的5个高技术产业均处于较高的RD效率上;区域间发展很不平衡,高技术产业行业差异比较明显;个别省市的5个高技术产业的RD效率都很低;传统"创新"大省RD效率并不突出,存在严重的资源浪费。针对存在的问题,从追求效率、追求精益、协同发展和加强政策引导等方面提出了对策与建议。     

Tourists’ aesthetic assessment of environmental changes,linking conservation planning to sustainable tourism development

Abstract

Tourists often travel to experience the natural beauty of a destination such as the Great Barrier Reef (GBR) in Australia. This nature-based destination attracts millions of tourists every year because of its outstanding underwater aesthetics. Recently, parts of the GBR have been degraded by warming sea temperatures and other local anthropogenic influences, threatening the Reef aesthetics and tourism in the region. In order to deal with this topical issue, the current research investigates tourists’ aesthetic assessment of environmental changes in the GBR ecosystem. Research outcomes indicate that tourists’ perceived beauty of the Reef is sensitive to environmental changes. The disappearance of sea animals (colourful fish, turtle), degrading coral and decreasing water quality negatively influence their aesthetic assessment, which can reduce tourist visitation in the long-term. Hence, sustainable tourism development in the GBR regions can only be achieved when government support for environmental management is strengthened. Conservation programs of the GBR should expand beyond coral restoration for controlling water quality, reducing pollution and protecting aesthetically appealing sea animals.     

Segmenting Visitors to Battlefield Sites: International Visitors to The Former Demilitarized Zone in Vietnam

Paradoxically, part of the appeal of Vietnam as an emerging destination lies in the commodification of images, artifacts, and battlefield sites of the Vietnam War. While studied from the supply-side, little research has been undertaken yet in terms of the patterns of demand for battlefield tourism. Based on a survey of 481 visitors to the former Demilitarized Zone (DMZ), this article uses factor analysis and cluster analysis to segment then profile battlefield visitors based on their motivations. Three groups of visitors to the DMZ were identified: the Battlefield Tourism Enthusiast, the Opportunist, and Passive Tourists. Significant differences were found between the three segments with regard to various sociodemographics and trip characteristics. However, results from the study also emphasize that analyses of demand based on site visits should be contextualized in terms of visits to the country as a whole and that care must be taken in distinguishing specialist visitors from generalists.     

Development and Pricing of a New Participating Contract

Abstract

This article designs and prices a new type of participating life insurance contract. Participating contracts are popular in the United States and European countries. They present many different covenants and depend on national regulations. In the present article we design a new type of participating contract very similar to the one considered in other studies, but with the guaranteed rate matching the return of a government bond. We prove that this new type of contract can be valued in closed form when interest rates are stochastic and when the company can default.     

Financial liberalization and bank efficiency: a comparative analysis of India and Pakistan

This paper provides a comparative analysis of the evolution of the technical efficiency of commercial banks in India and Pakistan during 1988–1998, a period characterized by far-reaching changes in the banking industry brought about by financial liberalization. Data Envelopment Analysis is applied to two alternative input–output specifications to measure technical efficiency, and to decompose technical efficiency into its two components, pure technical efficiency and scale efficiency. The consistency of the estimated efficiency scores are checked by examining their relationship with three traditional non-frontier measures of bank performance. In addition, the relationship between bank size and technical efficiency is examined. It is found that the overall technical efficiency of the banking industry of both countries improved gradually over the years, especially after 1995. Unlike public sector banks in India, public sector banks in Pakistan witnessed improvement in scale efficiency only. It is also found that banks are relatively more efficient in generating earning assets than in generating income. This is attributed to the presence of high non-performing loans. In addition, it is found that the gap between the pure technical efficiency of different size groups has declined over the years.     

Dynamics of fine wine and asset prices: evidence from short- and long-run co-movements

This article examines short- and long-term price linkages among the majority of fine wine and equity markets over the period of 2003 to 2012. We do not consider the price index (LIV-EX 100 or 500), as is typically undertaken in previous studies, but rather examine the auction price series of the world’s most traded wine-vintage pairs (5 Bordeaux first growth, 8 Bordeaux second growth, 5 Burgundy, 3 Rhone, 4 Italian, 5 Californian, 1 Australian and 1 Portuguese). A global equity index is also included using the Morgan Stanley Capital International World. Cointegration procedures, the Granger non-causality test, and ECM are used to analyse short- and long-run relationships among these markets. The results indicate a strong effect of financial markets on wine prices and short-term causality for certain wines. Moreover, the findings indicate short-run causality between the wines themselves, revealing a leader (exogenous) or follower (endogenous) status of certain fine wines in price dynamics, and also long-run causality for endogenous wines. This approach is relevant to portfolio diversification strategies and allows price movements to be anticipated more accurately than using an index approach.     

Electronic Marketplace: A Distinct Platform for Business-to-Business (B-to-B) Procurement

Purpose: The purpose of this study is to examine whether buyers perceive different electronic marketplaces (EMs) as distinct types of procurement platforms. More specifically, it empirically investigates to what extent professional buyers expect different benefits from different EM types and perceive different barriers associated with their usage.

Methodology: A Web-based survey of purchasing professionals in the United States was conducted with 359 responses received. A multivariate analysis of variance (MANOVA) was performed to determine if there are significant differences between EM types with respect to expected benefits (market aggregation and inter-firm collaboration) and perceived barriers (financial risks and trust barriers).

Findings: The results show buyers' expectations of benefits differ significantly between public EMs (i.e., third-party exchanges and industry-sponsored marketplaces) and private EMs (i.e., private trading networks), and between neutral EMs (i.e., third-party exchanges) and biased EMs (i.e., private trading networks and industry-sponsored marketplaces). Likewise, their perception of barriers differs significantly between public and private EMs.

Research limitations/implications: The research confirmed empirically that EMs are a distinct platform for business-to-business procurement. Nevertheless, by examining EMs from business buyers' perspective, this study necessarily limits itself to purchasing-related issues.

Practical implications: By providing insights into buyers' perceptions, our findings can help managers focus their promotional efforts aimed at potential firms that would like to use EM for procurement by emphasizing specific benefits or addressing specific perceived barriers based on the type of EM they manage.

Originality/value: This study fills a void in academic literature on EMs that currently contains few empirical studies with respect to EM types. Its main contribution is in establishing empirically that EMs do not constitute a single, homogeneous marketspace but are instead comprised of distinct types that offer users specific benefits and expose them to certain risks.
