摘要：We investigate whether public opinion influences the level and structure of executive compensation. During 1992-2008, the negativity of press coverage of chief executive officer (CEO) pay varied significantly, with stock options being the most criticized pay component. We find that after more negative press coverage of CEO pay, firms reduce option grants and increase less contentious types of pay such as salary, although overall compensation does not change. The reduction in option pay after i...

摘要：In this paper we distinguish between two types of white lies: those that help others at the expense of the person telling the lie, which we term altruistic white lies, and those that help both others and the liar, which we term Pareto white lies. We find that a large fraction of participants are reluctant to tell even a Pareto white lie, demonstrating a pure lie aversion independent of any social preferences for outcomes. In contrast, a non-negligible fraction of participants are willing to te...

摘要：Several recent articles find that stocks with high probabilities of bankruptcy or default earn anomalously low returns and negative unconditional capital asset pricing model (CAPM) alphas in the post-1980 period. I show that the conditional CAPM resolves the performance difference between high- and low-distress stocks. In particular, financially distressed stocks have relatively low exposure to market risk during bad economic times. I help to explain these findings through a theoretical model ...

摘要：Sustaining operational productivity in the completion of repetitive tasks is critical to many organizations' success. Yet research points to two different work-design-related strategies for accomplishing this goal: specialization to capture the benefits of repetition and variety (i.e., working on different tasks) to keep workers motivated and provide them opportunities to learn. In this paper, we investigate how these two strategies may bring different productivity benefits over time. For our ...

摘要：A service plan is a type of optional warranty beyond manufacturers' base warranties that retailers offer to consumers. In this paper, we examine how a service plan affects the role played by a manufacturer's base warranty. Analysis shows that when consumers can assess product quality (i.e., the probability of product failure), the manufacturer's warranty is negatively affected by the presence of a service plan. In the presence of such a plan, a base warranty is offered only when the manufactur...

摘要：We present the result of research, developed within Nokia Siemens Networks, to solve the downlink subframe allocation problem in Mobile WiMAX (IEEE 802.16) technology in its full complexity, while simultaneously fulfilling real-life constraints on processing power and delay. We describe the IEEE 802.16 standard, and introduce two system models. A theoretical analysis of the two-dimensional packing problems originated by such models shows that they are both NP-hard in the strong sense. From a p...

摘要：One of the most important operational challenges faced by emergency departments (EDs) in the United States is patient overcrowding. In periods of overcrowding, an ED can request the emergency medical services (EMS) agency to divert incoming ambulances to neighboring hospitals, a phenomenon known as ambulance diversion. The EMS agency may accept this request provided that at least one of the neighboring EDs is not on diversion. From an operations perspective, properly executed ambulance diversi...

摘要：In this paper, we investigate the integrated information and pricing strategy for a seller who can take customer preorders before the release of a product. The preorder option enables the seller to sell a product at an early stage when consumers are less certain about their valuations. We find that the optimal pricing strategy may be highly dependent on the amount of information available at preorder and that a small change in the latter may cause a dramatic change in the proportion of consume...

摘要：The existence of mandatory emission trading schemes in Europe and the United States, and the increased liquidity of trading on futures contracts on CO2 emissions allowances, led naturally to the next step in the development of these markets: These futures contracts are now used as underliers for a vibrant derivative market. In this paper, we give a rigorous analysis of a simple risk-neutral reduced-form model for allowance futures prices, demonstrate its calibration to historical data, and sho...

摘要：The widespread implementation of customer relationship management technologies in business has allowed companies to increasingly focus on both acquiring and retaining customers. The challenge of designing incentive mechanisms that simultaneously focus on customer acquisition and customer retention comes from the fact that customer acquisition and customer retention are usually separate but intertwined tasks that make providing proper incentives more difficult. The present study develops incent...
