Social capital,user motivation,and collaborative consumption of online platform services

Collaborative consumption is broadly defined as sharing, obtaining, and giving access to products and services through peer networks online. As it is expected to resolve the societal and environmental problems, quite a few studies investigated consumers’ motivations that lead to positive attitudes and intention for collaborative consumption. This paper aims to study the determinants that motivate participants to perceive a positive attitude towards collaborative consumption focusing on three salient traits of social capital (shared goal, social interaction tie, and norms of reciprocity). The study found that social capital exerts a more substantial influence on intrinsic motivation (enjoyment and sustainability) than extrinsic motivation (economic benefit). The study also found that different social capital traits display different effects on motivation. In particular, the shared goal was a key determinant of both intrinsic and extrinsic motivation. And all three motivations positively affect collaborative consumption attitudes.     

What caused the rise of Airbnb? An examination of key macroeconomic factors

The social and economic implications of the Airbnb phenomenon have been the subject of much research. Yet, the academic literature on Airbnb is nascent. Specifically, the issue of whether major macroeconomic conditions affect the supply of Airbnb has not been investigated. To address this gap, we propose a conceptual model that explains the determinants of Airbnb supply and examine the extent to which major macroeconomic factors affect the supply of Airbnb. Specifically, we analyze the effects of hotel room rates (ADR), hotel demand, tourism demand, house prices, gross domestic product (GDP), wages and unemployment on the supply of Airbnb in 50 U.S. states. Results show that increases in hotel ADR, house prices, and GDP have contributed to an increase in the supply of Airbnb, whereas increases in unemployment rates and wages have adverse effects on Airbnb supply. Theoretical and policy implications are discussed within realms of macroeconomic theory.     

地位竞争动机对个体知识共享行为的影响

知识共享行为是学术界和企业界关注的焦点，虽然以往文献从多个角度和层次研究了组织中的知识共享行为，但忽视了地位竞争动机对个体知识共享决策的内在作用机制。基于地位竞争动机差异，将个体地位动机区分为支配型和威望型，以职场排斥为中介变量、组织公平氛围为调节变量，构建地位竞争动机对知识共享行为的影响过程模型，基于13个组织630套上下级配对样本数据进行实证检验。结果显示，支配型地位竞争动机负向影响知识共享行为，威望型地位竞争动机正向影响知识共享行为，职场排斥、组织公平氛围分别发挥中介效应和调节效应。结果为知识共享领域研究提供了新的视角和框架，揭示了地位竞争动机对知识共享促进和抑制作用的两面性，对企业管理实践有一定的现实意义。     

Maximizing political vote in multiple districts

This paper models a resource allocation problem in the political context. Voters and political candidates of two parties are positioned in each of n given electoral districts. We assume that each voter will vote for the candidate he is more attracted to. This attraction is modeled by an attraction function. Each of the parties now attempts to allocate a finite budget to maximize their objective, which is either the popular vote or the number of districts, in which the party has a majority. Individual scenarios are examined with respect to leader-follower solutions and Nash equilibria. The paper then describes a dynamic model that successively allocates existing funds plus additional donations to candidates in different electoral districts.     

Does Airbnb have a homogenous impact? Examining Airbnb’s effect on hotels with different organizational structures

Although a number of studies have examined Airbnb’s impact on hotels, previous studies have yielded mixed results and are limited in their geographical scope. Additionally, the impact of Airbnb on hotels with different organizational structures has not been previously analyzed. Accordingly, the purpose of this study is threefold: 1) to add to our understanding of the impact of an increase of Airbnb inventory by clarifying previously inconclusive results; 2) to examine the extent to which Airbnb listings affect hotel performance measures in the overall U.S. hotel market; and 3) to investigate the influence of Airbnb on key hotel metrics by elaborating the effect of Airbnb on hotels operated under different organizational forms- chain-managed, franchised, and independent. Our results show an adverse impact of Airbnb on hotel RevPAR and ADR metrics across different organizational structures. However, interestingly, Airbnb listings did not negatively affect occupancy numbers. Theoretical and practical implications are discussed.     

New measuring stick on sharing accommodation: Guest-perceived benefits and risks

As an emergent phenomenon fueled by advanced technology, the sharing economy enables people to capitalize on underutilized physical assets that would otherwise be wasted. Despite the rapid growth, existing empirical studies are limited to the adoption of scales from other disciplines, although collaborative consumption differs from commercial consumption. The purpose of the study is to examine guests’ perceived risks and benefits of sharing accommodation. Using three folded studies, this research attempts to yield key theoretical contributions by developing a scale for perceived benefits and risks in the context of sharing accommodation. Furthermore, this study provides initial insights into why consumers would avoid sharing accommodations while at the same time identifying potential benefits and risks in relation to attitude and behavioral intentions. The findings from this research will enable sharing accommodation hosts to understand consumers’ perceived benefits and risks and thus provide enhanced experiences to users.     

The effects of board structure on corporate performance: Evidence from East African frontier markets

The effectiveness of the well-known corporate governance practices may not be universal due to fundamental differences in the environments under which firms operate. By using hand-collected data from all the non-financial firms listed on the unexplored East African frontier markets (i.e., Kenya, Tanzania and Uganda), we examine the effect of board characteristics on the performance of firms. Our results show that board size has a negative and significant effect on firm performance. The presences of foreigners and civil servants on the board play positive roles on financial performance, where the agency and resource dependence theories apply. Further, we find that board members with higher education also contribute to firm performance. These findings still hold when we consider the 2008–2009 financial crisis period. Overall, we show that in a business climate where ownership is largely dominated by few shareholders, the conventional governance mechanisms do not work effectively.     

Exploring the motivations to use online meal delivery platforms: Before and during quarantine

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.
