Showrooming, a phenomenon in which customers use brick-and-mortar stores to assess products and then purchase them from online retailers (o-retailers) for lower prices, is considered a great threat to traditional retailers (t-retailers). To combat showrooming, many t-retailers have executed price matching which enables customers to pay o-retailers' lower prices for the identical product. To avoid direct competition with t-retailers who execute price matching, many o-retailers have begun to sell differentiated products from t-retailers, which weakens the information advantage to customers from practicing showrooming. Motivated by these observations, we construct a duopoly game, where a t-retailer and an o-retailer sell products in a same category, to study the profitabilities of product differentiation and price matching in the context of showrooming. The results show that in the scenario without price matching, the o-retailer is likely to benefit from product differentiation only when the o-retailer's differentiated product is more popular with customers than the t-retailer's product. However, in the price matching scenario, the o-retailer also has the opportunity to benefit from product differentiation when the o-retailer's differentiated product is less popular with customers than the t-retailer's product, and product differentiation can be a win-win strategy for the two retailers under certain conditions. Considering the o-retailer's product differentiation decision, the t-retailer is only likely to execute price matching if the non-digital attributes of the product category sold by two retailers are not very obvious.  相似文献

ABSTRACT

The purpose of this research is to analyze whether the Brazilian economy behaved under a wage-led or profit-led regime between 1960 and 2011, considering a Post-Kaleckian model in a context of external constraints. The time span is limited by data availability (i.e., 2011). To answer the question of whether the Brazilian economy works under a wage-led or profit-led regime, we propose a simple Post-Kaleckian model. The model suggests that a profit-led regime is more probable for Brazil. Moreover, a wage-led regime occurs when a balance of payments constrained growth model is taken into consideration. Likewise, the real exchange rate has a positive impact on economic growth through the export channel. This result is a novelty in the recent literature about the relationship between real exchange rate and economic growth within a Post-Kaleckian model. The Brazilian economy was chosen as it is one of the biggest economies in Latin America.  相似文献

Family firms bear two types of agency costs, including type I and type II agency problems, in corporate environmental practices: (1) Outside executives at family firms hesitate to engage in environmental strategies, which can lead to drops in profits; (2) Controlling families employ opportunistically environmental management to achieve their interests. We argue that a primary cause for the agency problems lies on ineffective internal corporate governance at family firms, which can cause loss of managerial (or power) balance between outside executives and family executives. Our findings show that family firms with ownership and strategic control (FSC), which family executives and outside executives monitor and constrain each other, can achieve the highest environmental performance. Moreover, external controls, including product market competition and provincial environmental regulations, substitute effective internal control of FSC. The environmental performance premium of FSC is more prevalent when the production market competition is lower. Family firms with ownership, operational, and strategic control (FOSC) can achieve higher environmental performance within a province with more stringent environmental regulations.  相似文献

Drawn on the upper echelons theory, this study investigates how chief executive officer (CEO) hometown identity drives firm green innovation. We propose that CEO hometown identity has a positive impact on a firm's green innovation performance. Furthermore, we explore the moderating role of managerial discretion determined by organizational and environmental factors (i.e., institutional ownership and market complexity). We propose that institutional ownership negatively moderates the positive relationship between CEO hometown identity and green innovation, but market complexity plays a positive moderating role. Using Chinese publicly listed firms from 2002 to 2016 in heavily polluting industries, our findings support these hypotheses. Our research contributes to the upper echelons theory and corporate social responsibility literature and has substantial practical implications.  相似文献

Although the mechanism of internal branding is related to both organizational factors and employees’ personal factors, the existing research mainly focuses on organizational factors. Thus, the literature on the formation and function of internal branding from the employee perspective is scarce. In this multisource study, we applied self-categorization theory to test the relationships among employees’ feeling trusted, perceived insider status, self-efficacy and taking-charge behaviour within the framework of internal branding. Data from 169 employee-supervisor dyads from the hotel industry in Northwest China revealed that employees’ perception of feeling trusted is an important factor that causes them to internalize their hotel employer’s brand and categorize themselves as “insiders” who regard the hotel brand as part of themselves and present brand-aligned behaviour to achieve brand success. In addition, employee self-efficacy is an important boundary-level variable that facilitates the transformation of brand internalization to brand-aligned behaviour. The theoretical and practical implications are discussed.  相似文献

Rapid population ageing increases interest in economic flows across ages and intergenerational transfers in general. This article uses the National Transfer Accounts methodology to measure consumption and production at each age, and how the difference between consumption and production is financed through (private and public) transfers and the interaction with assets, i.e. ‘asset-based reallocations’. During working ages, people earn more than they consume and with the surplus they finance the deficit of the young and old generations who consume more than they produce. Such a pattern of economic dependency is universal across countries and across time, but huge differences exist in the ages at which individuals produce more than they consume and vice versa. Moreover, the importance of private and public transfers and asset-based reallocations varies across countries and times. In the last three decades, life expectancy at birth in Slovenia increased by 9.3 years, while the age span in which production exceeds consumption narrowed rather than increased. Child dependents are predominantly financed by private transfers, whereas the elderly mainly rely on public transfers. Young and old individuals increasingly rely on public transfers. Together with rapid population ageing, this is likely to jeopardise the public finance system in the future.  相似文献

Online meal delivery platforms (OMDPs), like UberEats, have received more attention since quarantine was established to prevent the spread of COVID-19. The research into antecedents of satisfaction and continuous usage intention for OMDPs, in general, is under researched. The current study compared the antecedents of satisfaction before quarantine to the antecedents during quarantine through the lens of Expectation-Confirmation Theory. Through multiple regression analyses, the researchers found that before quarantine, sharing economy ethos, price-value, food quality, ease of use and confirmation of beliefs had a significant impact on satisfaction while during quarantine, food quality, service speed, ease of use, and confirmation of beliefs were significant. Practical and theoretical implications are discussed.  相似文献
