  Impacts of Product Display Formats and Shopping Motivation on Consumers’ Online Product Search

  We investigate the effects of interface designs on consumerrsquos approach and herd behavior on social commerce sites. Specifically, we compare two prevailing formats of product display, i.e., a matrix format vs. a waterfall format. Based on environmental psychology model and cue selection effect, we propose that product display formats influence consumer product search behavior on online social commerce platforms and the effects are further moderated by consumerrsquos shopping motivation. We conducted an eye-tracking experiment using 120 subjects. Our empirical findings suggest that

  Contingent Stimulus in Crowdfunding

  Reward-based crowdfunding is a form of innovative financing that allows project creators to raise funds from potential backers to start their ventures. A crowdfunding project is successfully funded if and only if the predetermined funding goal is achieved within a given time. We consider a model where backers arrive sequentially at a crowdfunding project. Upon arrival, a backer makes her pledging decision by taking into account the expected success of the project. We characterize the dynamics of a project's pledging process. In particular, we show that there exists a "cascade effect" on backers'

  Simultaneous vs. Sequential Crowdsourcing Contests

  In a crowdsourcing contest, innovation is outsourced by a firm to an open crowd that competes in generating innovative solutions. Given that the projects typically consist of multiple attributes, how should the firm optimally design a crowdsourcing contest for such a project? We consider two alternative mechanisms. One is a simultaneous contest, where the best solution is chosen from the aggregate solutions simultaneously submitted by all contestants. The other is multiple sequential sub-contests, with each dedicated to one attribute and the contestants asked to build upon the best work in progress from previous sub-contests. It is intuitive that the sequential contest has the advantage of potentially creating a ldquocooperativerdquo final solution contributed by different contestants.

  When Microfinance meets Crowdfunding

  While Internet platforms may bypass traditional intermediaries, some Internet platforms reach target customers through collaborations with offline service providers, especially when the target customers are underprivileged or hard to reach. Such collaboration is not only essential for the online platform it also brings changes to the operation of the offline service. We analyze the impacts of the collaboration between microfinance institutions (MFIs) and one of the largest prosocial lending platforms, Kiva.org. We found that partnership with Kiva not only brought MFIs new capital resources, it also helped to improve the management efficiencies. To empirically establish the causal impacts,

  Stock or Print? Impact of 3D Printing on Spare Parts Logistics

  We present a general framework to analyze and quantify the impact of 3D printing on spare parts logistics. We consider multiple parts facing stochastic demands. To minimize long-run average system cost, our model determines which parts should be printed and which should be stocked and the corresponding base-stock levels. When a demand for a stocked part encounters a stockout, it can either be backlogged or overflowed to the 3D printer. We derive various structural properties and characterize the optimal policy for several special systems, which lead to efficient near-optimal heuristic solutions for the general system. We demonstrate that adopting 3D technology can yield significant cost savings and this impact increases in part variety.
