The purpose of this paper is to investigate the impact of incentive contracts in multi-partner project teams (MPPTs) on the agents’ effort expenditure and project performance, analyze how the agents allocate their efforts between production and cooperation and offer suggestions for project managers on how to design incentive contracts.

The paper proposes a model of MPPT in which agents are inequity-averse and their effort expenditures are exogenously bounded. An extensive numerical example is presented in online Appendix 2 to illustrate the theoretical results.

The paper suggests that if the potential benefit of the agents’ cooperation in MPPT is high or if both agents exhibit inequity aversion and the efforts’ marginal costs are low, then group-based incentive contracts outperform individual-based incentive contracts. It also shows that the impact of the incentive contract on the agents’ effort expenditure and project team performance is correlated with several critical project attributes.

Fulfilling a need to study the design of incentive structures in MPPTs, the paper complements the existing literature in three ways. First, in contrast to single-partner project teams, it considers projects with multiple partners where cooperation between them enhances the project outcome. Second, rather than focusing on individual production problems, it considers multi-task projects with constrained efforts that must be allocated between production and cooperation. Third, it analyzes the effects of changes in the project attributes, incentive intensities and information transparency on the effectiveness of the contract.

We design an experiment to investigate the influence of announced future variations in interest rates and prices on consumption decisions. In an experimental implementation of the discounted utility model, the subjects learn the entire paths of inflation and interest rates prior to deciding on a consumption path. We decompose the total change in consumption that results from changes in either interest rates or inflation rates into anticipation and impact effects. While impact effects are of similar orders of magnitude as in the model, future changes in inflation or interest rates exert substantially smaller effects on current consumption than predicted by the model.

Trust is a key concept in business, particularly in electronic commerce (e‐commerce). In order to understand online trust, one must first study trust research conducted in the offline world. The findings of such studies, dating from the 1950’s to the present, provide a foundation for online trust theory in e‐commerce. This paper provides an overview of the existing trust literature from the fields of philosophy, psychology, sociology, management, and marketing. Based on these bodies of work, online trust is briefly explored. The range of topics for future research in online trust in e‐commerce is presented.

Purpose and approach – We examine theoretically and experimentally how unequal abilities to contribute affect incentives and efficiency when players compete for membership in stratified groups based on the contributions they make. Players have either a low or a high endowment. Once assigned to a group based on their group contribution, players share equally in their group’s collective output. Depending on the parameters, the mechanism has several distinct equilibria that differ in efficiency.

Findings – Somewhat counter to conventional expectation our theoretical analysis indicates that as long as certain assumptions are satisfied, efficiency increases rather than decreases the more abilities to contribute differ. The analysis also suggests various follow-up experiments about equilibrium selection, tacit coordination, and the effect of unequal abilities in systems with endogenous grouping. We conduct an experiment that shows that subjects tacitly coordinate the mechanism’s asymmetric payoff-dominant equilibrium with precision; this precision is robust to a change in the structure and complexity of the game.

Implications – The results suggest that people respond to merit-based grouping in a natural way and that competitive contribution-based grouping encourages public contributions even when abilities to contribute differ, which is the case in all communities and societies.

The objectives of this paper are to examine the impact of psychological contract on project performance in private construction projects and to investigate if the positive effect of psychological contract on project performance can be mediated by inter-organisational teamwork.

Multiple regression analysis and mediation analysis were applied in this study to conduct the proposed hypotheses. Data were collected via questionnaire surveys from the construction professionals working for contractor firms on private construction projects.

The result of the multiple regression analysis indicated that psychological contract between contractors and owners is significantly related with project performance in construction projects. This study examined five psychological contract components, but the most important element was found as trust which can influence every aspect of project performance. Fairness is another key factor that can improve project performance in terms of budget and quality. Further, the findings of the mediation analysis revealed that inter-organisational teamwork has a mediating effect on the relationship between psychological contract and project performance.

This paper presents the important role of psychological contract between contractor and owner organizations in construction projects that can affect project performance. The study also highlights the significance of inter-organisational teamwork as a mediator to the relationship between psychological contract and project performance.

Trust has been widely recognized as the crucial factor of consumer purchase intention when shopping on peer-to-peer short-term rental platforms where hosts and renters are strangers. However, the specific attributes of hosts that help build trust with potential renters and drive their purchase of short-term rentals remain unknown. This study aims to explore the effects of host attributes on renter purchases made on Xiaozhu.com, one of the top short-term rental platforms in China, while controlling for short-term rental characteristics.

A crawler program was developed by Python to collect the host attributes and their short-term rental characteristics of 935 hosts in Beijing from November 18, 2015 to February 14, 2016. The authors use Poisson regression models to estimate the effects of host attributes on renter reservations. They also conduct a series of robustness checks for the estimated results.

The authors found that host attributes such as the time of reservation confirmation, the acceptance rate of renter reservations, the number of listings owned, whether a personal profile page is disclosed and gender of the host significantly affect renter reservations, whereas the response rate of the host does not influence renters when purchasing short-term rentals online.

This study identifies which host attributes are perceived as trustworthy and affect renters’ purchase decisions, a topic of both theoretical and practical importance but currently less researched. The findings add to emerging literature by providing insights on trust-building in the peer-to-peer economy. Useful suggestions are also provided on strengthening the trust mechanism on short-term rental platforms to facilitate peer-to-peer transactions. Notably, the study is the first attempt to examine the perception of Chinese users toward short-term rentals despite its global prevalence. The analytical insights revealed from large scale but granular online observations data of host attributes and actual renter reservations greatly supplement findings of extant literature using survey and experiment approaches.

Contractors rely on effective pricing methods in order to translate potential business into reality for long-term survival of their firms. This involves effective utilization of bidding feedback information toward winning jobs with high profit potential. The purpose of this paper is to experimentally investigate student (inexperienced) bidders’ competitiveness under full and partial information feedback conditions when the number of competing bidders is large (n=12).

This paper adopted an experimental research design. The design used between-subjects variation and involved information feedback as the treatment variable with 120 students who enrolled in a cost-estimating course participated in the experiment.

The result shows that the variations in bids over time for both levels of information feedback are statistically significant. It is found that bidders with full bidding feedback information are more competitive than those with partial bidding feedback information. The bid-spread analysis and the identified effect of these two information feedback conditions on awarded contract sum, provide some further evidence that full information feedback condition would lead to lower average bids in construction bidding.

The implication of the findings for construction clients is that they should provide as much bidding feedback information as possible so that the bid prices will be competitive.

Given the ambiguity inherent in field data, this paper provides strong justification of using experimental research design in advancing the understanding of construction pricing under different information feedback conditions. In addition, it demonstrated the suitability of using student subjects in similar experiments in the context of construction bidding.

The purpose of this paper is to describe a study in which a previously validated measurement instrument is used to investigate the existence and importance of specific factors that are thought to predict the generation of consumer trust in internet shopping in Ireland.

A sample of 858 individuals was surveyed using a previously validated measurement instrument that focused on a number of key constructs identified in the literature as potential trust predictors.

The study results provide evidence that Irish consumers' trust in internet shopping is the result of specific factors, the first of which relates to the vendor's perceived integrity, and the second of which relates to the vendor's perceived competence. The former encompasses social antecedents of trust, while the latter encompasses the technical antecedents of trust.

The insights provided by this research make a valuable contribution not only to information systems research, but also to the overall body of marketing, trust and diffusion research. The findings of this research are of potential benefit to online vendors of all types who seek to engender consumer trust in their web sites.
