Analyzing Consumer Preference for Wine Product Bundles: Implications for the Retail and Wine Industry

This research examines a marketing technique (bundling) that wine companies may use to gain access to retail stores. The study examined consumers' perception toward bundling with respect to the Australian wine market and the results allowed for the formulation of market segments, which aimed to provide a better understanding of the wine-bundle purchaser. Cluster analysis highlighted three market segments, in particular, one consumer segment is prone to purchasing wine bundles and is interested in deals. While exploratory in nature, the research may provide an insight into global wine marketing strategy.     

Customers’ migration paths decided by relative advantage: longitudinal and comparative case study of successive generations of logic semiconductor technology

ABSTRACT

Understanding customers and their behaviour has become important for success in a market. When successive generations of technology are available in a market, customers will decide their migration paths based on certain factors. This study focused on the relative advantage of successive generations positioned at different levels. Based on a longitudinal and comparative research design, the migration paths of customers are identified by understanding how their behaviours are affected by this relative advantage. The preferred relative advantage is positioned differently at early and majority markets. According to observations of the actual migration paths of 14 semiconductor customers, early and majority market players exhibit different migration paths (switching, new entrance, leapfrogging, or diffusion paths) depending on the relative advantage of the migrating generation. This study has theoretical implications by understanding the mechanism of customers’ migration based on the relative advantage, as well as practical implications for suppliers and customers to sustain their competitive advantage in a market.

Repetitive disclosures in the MD&A

This study is the first to empirically analyze repetitive disclosures in the Management Discussion and Analysis (MD&A) section of the 10‐K filing. Repetitive disclosures refer to the extent that content in the MD&A is repeated from the audited financial statement notes. I empirically analyze repetitive disclosures in the MD&A section of the 10‐K filing, and find that firms tend to use more repetitive disclosures when firms have a new CEO, a high level of new disclosures in the notes, issued equity, and have missed the prior year's earnings benchmark. These findings suggest that not all managers use repetitive disclosures to simply obfuscate disclosures. Rather, some managers use repetitive disclosures to emphasize firm‐specific events, consistent with the succession hypothesis. The Securities and Exchange Commission (SEC) states that repetitive disclosures are uninformative and that such disclosures decrease the informativeness of other disclosures in the MD&A. Casting doubt on the SEC's comments, in my primary analyses, I find that repetitive disclosures are informative to investors; this result is stronger for individual investors. Overall, my results suggest that repetitive disclosures are informative, and such disclosures may be effective tools for providing information to investors.     

Successive Approximation Linear Quadratic Regulator for Estuarine Management Problem

A successive approximation linear quadratic regulator (SALQR)method is applied to solve estuarine management problems to determine the optimal amount of freshwater inflows into baysand estuaries to maximize fishery harvests. Fishery harvests areexpressed in regression equations as functions of freshwaterinflows. The optimization problem is posed as a discrete-timeoptimal control problem in which salinity represents the statevariable and freshwater inflow represents the control variable. A two-dimensional hydrodynamic-salinity transport model, HYD-SAL,is used as the transition to simulate the flow circulation andtemporal and spatial salinity pattern in an estuary system. Thebound constraints for the control and state variables areincorporated into the objective function using a penalty functionmethod to convert the problem into an unconstrained formulation. The SALQR method is applied to the Lavaca-Tres Palacios Estuaryin Texas and the results are compared with those of usingregression equations as the transition equations.     

Stated Attribute Non‐attendance in Successive Choice Experiments

Attribute non‐attendance in choice experiments affects willingness‐to‐pay (WTP) estimates and therefore the validity of the method. A recent strand of literature uses attenuated estimates of marginal utilities of ignored attributes. Following this approach, we propose a generalisation of the mixed logit model, whereby the distribution of marginal utility coefficients of a stated non‐attender has a potentially lower mean and lower variance than those of a stated attender. Model comparison shows that our shrinkage approach fits the data better and produces more reliable WTP estimates. We further find that while reliability of stated attribute non‐attendance increases in successive choice experiments, it does not increase when respondents report having ignored the same attribute twice.     

认知错觉对村民留用地安置意愿的影响 ——来自广州市438个村民样本的经验证据

研究目的：厘清村民认知错觉内涵,分析认知错觉对村民留用地安置意愿的影响,为破解留用地安置困局提供政策优化路径。研究方法：问卷调查法、二元logistics回归模型。研究结果：（1）产权认知错觉显著抑制了村民对留用地安置方案的接受意愿,尤其是禀赋效应的存在,使村民在留用地使用上利益导向突出,阻碍了村民接受留用地安置方案;（2）锚定效应引致村民对留用地价值产生认知错觉,继而显著遏制了村民对留用地安置方案的接受意愿;（3）正面的政府动机刻板印象,即村民在冲突经历、公平程度、认可度方面对基层政府和村委的正面评价,显著促进了村民留用地安置决策进程。研究结论：亟需重视村民对留用地政策的认知偏差带来的工作障碍,应采用群众喜闻乐见的方式、多渠道地提升村民对留用地政策的认知水平,同时,重塑基层政府的公信力,消融村民对政府的负面刻板印象。

锚定效应影响下初始知识积累水平对创新决策影响研究

资源与能力互补在成为协同创新重要驱动力的同时,也肯定了创新主体的资源与能力客观上存在差异,这一差异是否对协同创新行为决策产生影响、资源与能力优势是否意味着高的创新努力水平,成为推进协同创新首先需要回答的问题。引入行为经济学锚定效应理论,将初始知识积累水平作为资源差异和决策参照,从知识积累角度构建锚定效益影响下的创新收益与创新投入模型。通过模型演算得到,与通常认为的不一致的是,高初始知识积累水平可能对创新努力程度产生负面影响,联盟中创新努力程度高的主体并非那些初始知识积累水平高的主体;高初始知识积累水平在联盟形成的初始阶段有助于提升号召力,但委托方高学习效率在联盟运行后更易激发协作方的“搭便车”行为。通过算例和案例对模型结论进行验证。
