Contextual Framing and Monetary Incentives in Field Experiments on Risk Preferences: Evidence from German Farmers

Recent studies cast doubt on the ability of abstract experiments to predict decision‐making in the field. Thus, scholars have argued for more ‘realism’ by introducing context to field experiments. Yet, such realism may work against the induced values of monetary incentives in economic experiments. It is an open question whether contextual framing works best with or without inducing values, through methods such as the use of monetary incentives. Using a sample of 146 German farmers, we compare experimentally the predictive power of a framed lottery in an agricultural context vs. using an abstract version. For one half of the sample, lotteries are incentivised; for the other half, they are hypothetical. Although risk preferences differ between treatments, all four lottery tasks correlate poorly with farmers’ real‐world use of risk management instruments such as harvest or hail insurance. Subjects who start with an agricultural framing are willing to take significantly greater risks in the lotteries. More generally, our findings cast doubt on the ability of lottery tasks to predict risk‐taking in the field.     

Threats to the Validity of Logistics and Supply Chain Management Research

To increase the relevance of logistics and supply chain academic research, this paper recommends the development and testing of middle‐range theory and practice‐level theory. Yet, there are a number of research issues that arise when academic researchers test middle‐range and practice‐level theory, both in measuring constructs and in testing theoretical relationships between constructs. Concerning the measurement of constructs, this paper recommends that academic researchers pay more attention to content validity and undertake rigorous processes to ensure content validity. In addition, academic researchers need to more explicitly define constructs as either reflective or formative. If the construct is defined as formative, then the traditional statistical approaches to validate these measurement scales are not recommended. The appropriate use of employing single‐item measures for concrete constructs is discussed. In regard to conducting hypothesis tests, research issues associated with multicollinearity and omitted variable bias are discussed. Relative weight analysis is ideal for testing theoretical models and research hypotheses when survey data are obtained, multicollinearity is present, and there are a large number of independent variables predicting a dependent variable. Thus, relative weight analysis is ideal for testing research hypotheses in logistics and supply chain management.     

The institution efficiency of stock price limits： An experimental analysis on the two stocks market with continuous bid

Price limits in product market have been discarded in classic microeconomics. However, price limits affect the trade behavior of the same agent, since agents in the stock market change their trade status frequently. Due to the controversy on the institution effectiveness of the price limits in stock market, this paper design an experimental market with two stocks with continuous bid, in which we investigate the impact of the price limits on the stock market. The results show that the price limits moderate the price volatility within and between the trades periods, thus can stabilize stock price. In addition, price limits, when measured by traditional approach, restrain the fluidity of the market, reduce the volatility of transaction shares and maintain durative of fluidity. While volatility-based fluidity measurements show that the fluidity is enhanced significantly in stock market with price limits.     

What makes a good case study? A positivist review of qualitative case research published in Industrial Marketing Management, 1971-2006

Business-to-business marketing research has a long tradition of using qualitative case studies. Industrial Marketing Management (IMM) has actively encouraged the use of case methods, resulting in many important theoretical advances in the field. However, debate still rages over what constitutes “good case research”. This article addresses this issue from a positivist standpoint. We examine the how authors address issues of quality in the 105 qualitative case studies published in IMM between 1971 and 2006. Four periods were identified: 1971-1979, 1980-1989, 1990-1999, and 2000-2006. Findings demonstrate that, from a positivist viewpoint, there has been a steady improvement in how authors addressed issues of research quality in published qualitative case studies. Suggestions for changes in data presentation, reviewer expectations, the IMM reviewer feedback form, and the use of web-based appendices containing data pertinent to reader judgments of research quality are suggested.     

GIS属性信息可视化及其有效性分析

专题地图是GIS属性信息可视化表达的一种重要方式,但存在一个缺陷就是地区面积大小与属性信息的数量差别太大影响读图者的视觉。面域拓扑图是对面状区域分布的专题属性定位表达,对空间区域的形状进行几何变换,使得面积大小与表达的属性信息数量成一定比率关系,将区域内的属性信息映射为面积大小来表达其间的数量差异。通过调查分析,面域拓扑图在表达GIS数量信息时比专题地图具有较好有效性。     

Factors associated with hunter retrieval of deer hit by arrows and shotgun slugs

Abstract

Hunter retrieval of wounded deer was used as a case study to examine applications and limitations of leisure research for the management of recreational behavior. All hunters receiving permits to hunt in the Shiawassee National Wildlife Refuge during November 1–20, 1983, were sent mail questionnaires. A total of 457 (93 percent) of the archery and 143 (95 percent) of the firearm permittees responded after 3 mailings. Archery deer hunters were estimated to have retrieved 29 (43 percent) of the 68 different deer hit by arrows. Shotgun hunters were estimated to have retrieved 42 (81 percent) of 52 different deer hit. Discriminant analysis showed that the retrieval of deer hit with arrows was most likely when the shooter had tagged a large number of deer during former archery hunts, when the deer was hit in a position other than broadside, and when the range of the shot was short. Deer hit with slugs were more likely to be retrieved when hit by hunters with little experience in tagging deer during former firearm hunts, when the shooter also hunted deer with a bow and arrow, and when the shot was taken at deer that were not running. These data were interpreted to suggest how retrieval rates might be increased through regulation, education, and management of the recreational environment. The role of leisure research and theory in providing techniques and a rationale for modifying the behavior of recreationists is discussed.     

National parks in the third world and associated national characteristics

Abstract

For 102 third world countries, presence and absence of national parks is used as the dependent or classification variable in a discriminant analysis. Eleven variables suggestive of diverse tropical savanna habitats contribute to a single canonical discriminant function. Socioeconomic variables are poor contributors to the function. Seventy‐nine of the countries are properly classified in their group by the canonical discriminant function. Misclassification focuses on sub‐Saharan Africa where many countries have established parks under “improper”; conditions, and strong positive association with the function calls attention to Latin America.     

Using a Validation Process to Develop Market Segmentation Based on Travel Motivation for Major Metropolitan Areas

Studies on market segmentation based on travelers' push motivation have been conducted without implementing a statistically validated procedure for establishing the segmented markets. The purpose of this study is to identify validated traveler market segments by examining what travelers' push motivation dimensions are among the heterogeneity of travelers to a major metropolitan area. The six push motivation dimensions were extracted from the 20 motivation items by conducting factor analysis (i.e., Social/Interaction, Excitement/Fun, Relaxation, Sightseeing, Family/Friends, and Sports). Cluster analysis identified the three homogeneous groups of travelers. Subsequent discriminant analysis verified the existence of the three travelers' markets in the metropolitan area. Managerial implications are suggested for the three push motivation‐based segments.     

A Cluster Analysis of Young Adult College Students' Beef Consumption Behavior Using the Constructs of a Proposed Modified Model of Planned Behavior

The theory of reasoned action (TRA) served as the theoretical framework for this study. This study focused on the development and analysis of a proposed modified model of planned behavior (MMpB) to investigate the beef consumption habits of young adult college students. The participants were a convenience self-selected sample of young adult college students from a major southeastern and southwestern university. A self-report survey was administered to (N = 914) students in classrooms at both universities. Using cluster and discriminant analysis three distinct cluster groupings were found based on the behavior construct.     

Postservice Recovery Customer Satisfaction in Indian Retail Banking: Scale Development and Validation

The construct of postservice customer satisfaction with respect to Indian retail banking has been studied. Furthermore, the development and validation of the postservice recovery customer satisfaction scale in Indian retail banking is detailed. The scale development process was carried out over three stages (item generation, scale purification, scale validation) and comprised of conducting depth interviews and focus groups for item generation and three separate phases of data collection, involving a total of 851 individual respondents. The data provide evidence for face, content, discriminant and convergent validity, dimensionality, reliability, and generalizability of the customer satisfaction scale in Indian retail banking.
