干部经历会影响农户选择电商销售渠道吗?——基于荔枝种植户的实证分析

基于印记理论,选取2020年广东和广西两省荔枝主产区的964户种植户作为调研对象,运用logit模型进行实证分析,探索干部经历对农户选择电商销售渠道的影响。结果显示:干部经历对荔枝种植户采用电商销售具有显著的正向影响,而农户自身具有的销售渠道资源也是荔枝种植户选择电商销售的动力之一,其与干部经历带有的政治资本共同推动种植户选择电商销售。因此,要发挥具有干部经历的农户在农产品电商发展中的带头人作用,培育当地的销售服务团队与提供更多的销售渠道资源,并联合社会多方力量加大对农产品电商销售的培训力度。     

Does travellers’ casual attribution affect pre-recovery emotions and behavioural intentions? A field study of airline travellers in Malaysia

This study examines the relationship between airline travellers' casual attribution, pre-recovery emotions, and negative behavioural intentions after a service failure and proposes a model for analysing direct effects of airline travellers' casual attribution of stability (failure frequency) and controllability (the extent to which the airline can control the failure) on negative behavioural intentions as well as its indirect effects through pre-recovery emotions. Data were gathered through a survey of airline travellers who experienced a failure in the past six months. The results indicate that both dimensions of casual attribution influenced pre-recovery emotions and negative behavioural intentions, and that pre-recovery emotions were significantly related to negative behavioural intentions. In addition, the results verify the mediating effect of pre-recovery emotions on the relationship between casual attribution and behavioural intentions. These results have important managerial implications.     

Achieving relational outcomes in casual dining restaurants through consumer commitment

The purpose of the study is to identify how we can achieve positive word-of-mouth (WOM) and share of purchases through consumer commitment in casual dining restaurants. This study proposes the theory of organizational commitment and the framework of the relationship development process as the theoretical foundation to identify the antecedents of consumer commitment (i.e. identification, switching costs, and satisfaction), and tests the role of consumer commitment between its antecedents and relational outcomes (i.e. share of purchases and positive WOM). The results of the study support that commitment plays a partial mediating role in the relationship between its antecedents and share of purchases. In addition, commitment exerts a full mediating role on the effects of identification and switching costs on positive WOM intentions, while it plays a partial mediating role between satisfaction and positive WOM intentions. Managerial implications are discussed to maximize delivering relational outcomes based on consumer commitment and its antecedents.     

A theoretical framework of electronic word-of-mouth against the backdrop of social networking websites

This study proposed and tested a theoretical framework that explains electronic word-of-mouth (eWOM) against the backdrop of social networking websites (SNWs), which have gained substantial popularity among travelers. In particular, a United States (US) nationwide online survey was conducted and nine hypotheses were tested. The findings suggest that willingness to share knowledge and switching costs are positively related to eWOM communication. In addition, customer value (utilitarian) has positive relationships with willingness to share knowledge, perceived security, and switching cost, while customer value (hedonic) has positive relationships with willingness to share knowledge and switching costs. Last but not least, the findings indicate that perceived security does negatively impact eWOM. In light of the major findings, the article sets forth strategic implications for travel-related social networking websites.

Coordination in retailer-carrier channels for long term planning

We study a retailer-carrier channel for the purpose of long term planning and coordination. Here, the term channel represents the business interaction between the retailer and the carrier. The retailer sells a particular item with price-dependent demand, whereas the carrier is responsible for transporting the item to the retailer's site. We characterize the profit functions of each channel member as well as the total channel profit. We consider two specific channel structures: (i) the centralized channel and (ii) the decentralized channel. Under the first channel structure, the goal is to set the retail price so as to maximize the total channel profit. Under the latter, the carrier and the retailer choose their own policy parameters, i.e., the freight rate for the carrier and the retail price for the retailer, so as to maximize their individual profits. We model the decentralized channel as a Stackelberg Game and propose a coordination mechanism between the retailer and the carrier in which the retailer signals a price multiplier to the carrier. We illustrate that this mechanism could provide win-win solutions for both parties and present analytical and numerical results on the efficiency of channel coordination. We demonstrate that coordination in retailer-carrier channels can be as promising as supplier-retailer channels. We also discuss the effects of retailer-carrier coordination on inventory levels.     

Product Patent Reform and its Impact on Korea's Pharmaceutical Industry

Our analysis focuses on the effect of U.S. government pressure on Korea to adopt product patents for chemical and pharmaceutical products. American pressure began in November 1985 and ended with the Korean Legislature's passage of a new patent law in December 1986. We conduct an event study of the effect of the new patent law on the value of Korean pharmaceutical firms listed on the Korea Stock Exchange. Regression analysis shows that the new law induced excess returns of-74 percent over the 14-month analysis period. The results suggest that adoption of stronger patent laws reduced Korea's wealth.

STRUCTURAL VECTOR AUTOREGRESSIONS: CHECKING IDENTIFYING LONG‐RUN RESTRICTIONS VIA HETEROSKEDASTICITY

Long‐run restrictions have been used extensively for identifying structural shocks in vector autoregressive (VAR) analysis. Such restrictions are typically just‐identifying but can be checked by utilizing changes in volatility. This paper reviews and contrasts the volatility models that have been used for this purpose. Three main approaches have been used, exogenously generated changes in the unconditional residual covariance matrix, changing volatility modelled by a Markov switching mechanism and multivariate generalized autoregressive conditional heteroskedasticity models. Using changes in volatility for checking long‐run identifying restrictions in structural VAR analysis is illustrated by reconsidering models for identifying fundamental components of stock prices.     

Exchange Rate Crises and Fiscal Solvency

This paper combines insights from generation one currency crisis models and the fiscal theory of the price level (FTPL) to create a dynamic FTPL model of currency crises. The initial fixed‐exchange‐rate policy entails risks due to an upper bound on government debt and stochastic surplus shocks. Agents refuse to lend into a position for which the value of debt exceeds the present value of expected future surpluses. Policy switching, usually combined with currency depreciation, restores fiscal solvency and lending. This model can explain a wide variety of crises, including those involving sovereign default. We illustrate by explaining the crisis in Argentina (2001).
