We consider a cash-constrained firm learning on the value of an irreversible project at a privately-known speed. Under perfect information, the optimal date of investment may be non-monotonic in the learning speed: better learning increases the value of experimenting further, but also the speed of updating. Under asymmetric information, the firm uses its investment timing to signal confidence in the project and raise cheaper capital from uninformed investors, which may generate timing distortions: investment is hurried when learning is sufficiently fast, and delayed otherwise. The severity of the cash constraint affects the magnitude of the distortion, but not its direction

We investigate the mechanisms that shape social comparison in organizations and generate socialcomparison costs. In particular, we focus on heterogeneity in the strength and type of incentivesand argue that, from an efficient design perspective, such variance in rewards is a double edgedsword. While the sorting and incentive effects that result may increase productivity, the socialcomparison processes that arise may dampen it. We posit that the mechanisms underlying thesebehavioral costs are shaped not only by the magnitude of reward variance, but by the formal andinformal design elements shaping the distance of advantaged peers. In other words, the moreproximate socially, structurally or geographically are those to whom one socially compares, thelarger the behavioral response. Empirically, we use an unanticipated event during which outlets ofa bank, previously operating under essentially homogenous incentives, were assigned totournament groups with differing ex ante probabilities of winning a prize—an event that increasesvariance in awards and hence generates an impetus for social comparison. We find that units withmore socially, geographically, and structurally proximate peers assigned to ‘advantaged’tournament groups decreased their productivity. We discuss implications of these results fororganizational design and boundaries

We consider a single-stage multiproduct manufacturing facility producing a large number of end products.In order to reduce overall inventory costs, an efficient approach is to produce some items according to amake-to-stock (MTS) policy and others according to a make-to-order (MTO) policy. Items priority levelsplay a key role in the optimal MTO/MTS decisions for such typical large-scale systems. To tackle this issue,the manufacturing facility is modeled as a multiproduct multipriority classes queuing system. We proposea general optimization procedure that selects near-optimal priority classes, gives the associated flow controlmode (MTO or MTS) for each product, and provides a lower bound and an upper bound with respect to theoptimal cost. First, we illustrate efficiency of our optimization procedure for this class of nonlinear integerprograms via several examples and by a numerical analysis, including a comparison with two alternativeheuristics given in the literature. In addition, we provide managerial insights by exhibiting, under variousparameter settings, the significant impact of an efficient priority level allocation among items on the inventorycosts and on optimal splitting between MTO and MTS product

The life-like collaborative potential offered by virtual worlds (VWs) has sparked significant interest for companies to experiment with VWs in order to organize convenient, cost-effective virtual global workplaces. Despite the initial hype, recent years have witnessed a rather stagnant use of VWs for collaboration in organizations. Previous research recognizes that the inherent uncertainties within the VW environment are factors limiting their utilization by businesses. Hence, grounding this research in uncertainty reduction theory (URT), we aim to understand the modalities and mechanisms for mitigating the uncertainties and fostering user trust within VWs so that they can be effectively utilized as a workplace collaboration tool. With this end in view, we propose contextualizing and extending McKnight et al.’s (2002) institutional trust framework to the context of VWs by examining the significant role that social presence has in influencing the efficacy of the institution-based trust-building factors of situational normality and structural assurance in VWs. Using a sequential mixed methods approach (Venkatesh et al. 2013; Venkatesh et al. 2016), this research integrates results from a quantitative study with findings from a qualitative study to arrive at rich and robust inferences and meta-inferences, with the qualitative method first corroborating the inferences obtained from the quantitative research and then complementing them by identifying boundary conditions that may limit the use of VWs in organizations for workplace collaboration. The results together suggest not only the direct, but also the interactional (complementary and substitutive) influences of social presence on the relationships of the two institutional-trust-building factors to user trust in VWs
