摘要：Consumers who are close to one another in a social network often make similar purchase decisions. This similarity can result from latent homophily or social influence, as well as common exogenous factors. Latent homophily means consumers who are connected to one another are likely to have similar characteristics and product preferences. Social influence refers to the ability of one consumer to directly influence another consumer's decision based upon their communication. We present an empirica...

摘要：The law of one price states that if prices for the same or highly similar goods vary across geographic locations by more than the cost of transport, then traders will shift supply and demand to exploit the price differences. However, several frictions prevent traders from doing this, including lack of information about prices and difficulty trading across locations. Electronic commerce has the potential to reduce these frictions by increasing price visibility and lowering transaction costs. We...

摘要：Using one of the largest samples of litigation data available to date, we examine whether the political culture of a firm determines its propensity for corporate misconduct. We measure political culture using the political contributions of top managers, firm political action committees, and local residents. We show that firms with a Republican culture are more likely to be the subject of civil rights, labor, and environmental litigation than are Democratic firms, consistent with the Democratic...

摘要：Demonstrating compelling causal evidence of the existence and strength of peer-to-peer influence has become the holy grail of modern research in online social networks. In these networks, it has been consistently demonstrated that user characteristics and behavior tend to cluster both in space and in time. There are multiple well-known rival mechanisms that compete to be the explanation for this observed clustering. These range from peer influence to homophily to other unobservable external st...

摘要：Contributing to a social cause can be an important driver for workers in the public and nonprofit sectors as well as in firms that engage in corporate philanthropy or other corporate social responsibility policies. This paper compares the effectiveness of a social incentive that takes the form of a donation received by a charity of the subject's choice to a financial incentive. We find that social incentives lead to a 13% rise in productivity, regardless of their form (lump sum or related to p...

摘要：We propose an intergroup competition scheme (ICS) to theoretically solve free riding in team production and provide experimental evidence from a voluntary contribution mechanism public goods game. The ICS includes an internal transfer payment from the lowest to highest contributing team proportional to the difference in group contributions. The ICS requires minimal information, makes the efficient contribution a dominant strategy, and is budget balanced. These features make the ICS ideally sui...

摘要：Do hospitals experience safety tipping points as utilization increases, and if so, what are the implications for hospital operations management? We argue that safety tipping points occur when managerial escalation policies are exhausted and workload variability buffers are depleted. Front-line clinical staff is forced to ration resources and, at the same time, becomes more error prone as a result of elevated stress hormone levels. We confirm the existence of safety tipping points for in-hospit...

摘要：Prior literature finds that long-lasting changes in firms' disclosure policies and information environment affect the cost of equity. Information asymmetry, however, also changes during the fiscal quarter. Firms disclose information periodically, and in between disclosure dates, traders can obtain private information, and adverse-selection risk increases. Such temporary increases in information asymmetry are usually considered to be diversifiable or too small to impact expected stock returns. ...

摘要：We consider the problem of optimal decision making under uncertainty but assume that the decision maker's utility function is not completely known. Instead, we consider all the utilities that meet some criteria, such as preferring certain lotteries over other lotteries and being risk averse, S-shaped, or prudent. These criteria extend the ones used in the first- and second-order stochastic dominance framework. We then give tractable formulations for such decision-making problems. We formulate ...

摘要：We consider large contact centers that handle two types of jobs-inbound and outbound-simultaneously, a process commonly referred to as call blending. Inbound work arrives to the system according to an exogenous arrival process, whereas outbound work is generated by the contact center. We assume that there is an infinite supply of outbound work to process, and that inbound calls are prioritized over the outbound calls. We propose a logarithmic safety staffing rule, combined with a threshold con...
