摘要:We consider the multiple-time-period, short-term production scheduling problem for a network of multiple open-pit mines and ports. Ore produced at each mine, in each period, is transported by rail to a set of ports and blended into products for shipping. Each port forms these blends to a specification, as stipulated in contracts with downstream customers. This problem belongs to a class of multiple producer/consumer scheduling problems in which producers are able to generate a range of product...

摘要:Statistical training helps individuals analyze and interpret data. However, the emphasis placed on null hypothesis significance testing in academic training and reporting may lead researchers to interpret evidence dichotomously rather than continuously. Consequently, researchers may either disregard evidence that fails to attain statistical significance or undervalue it relative to evidence that attains statistical significance. Surveys of researchers across a wide variety of fields (including...

摘要:We explore sell-side debt analysts' contributions to the efficiency of securities markets. We document that debt returns lag equity returns less when debt research coverage exists, which is consistent with debt analysts facilitating the process by which available information is impounded in debt prices. The effect of debt research on the debt market's lag is incremental to, but comparable in magnitude to, hedge fund ownership's effect. No such effect exists for credit rating agencies. We also ...

摘要:We study risk taking on behalf of others, both when choices involve losses and when they do not. A large-scale incentivized experiment with subjects randomly drawn from the Danish population is conducted. We find that deciding for others reduces loss aversion. When choosing between risky prospects for which losses are ruled out by design, subjects make the same choices for themselves as for others. In contrast, when losses are possible, we find that the two types of choices differ. In particul...

摘要:Consider a firm that would like to commit to a focused business strategy because focus improves efficiency and thus increases profit. We identify two general conditions under which tougher competition strengthens the firm's ability to commit to a focused strategy. Under these conditions, competition fosters commitment for two reasons: (i) competition reduces the value of the option to diversify (the contestability effect), and (ii) competition increases the importance of being efficient (the e...

摘要:The Hospital Readmissions Reduction Program (HRRP), a part of the U.S. Patient Protection and Affordable Care Act, requires the Centers for Medicare and Medicaid Services to penalize hospitals with excess readmissions. We take an economic and operational (patient flow) perspective to analyze the effectiveness of this policy in encouraging hospitals to reduce readmissions. We develop a game-theoretic model that captures the competition among hospitals inherent in HRRP's benchmarking mechanism. ...

摘要:Choices can be context dependent. This empirical finding is usually invoked to suggest that preferences are constructive and susceptible to decision environment. Yet preference construction can be systematic and endogenous. This paper develops the theory of contextual deliberation as a potential explanation for behavioral phenomena of preference construction. When preference ordering in a choice set is ex ante unknown and state dependent, decision makers can engage in information acquisition a...

摘要:Do higher wages elicit reciprocity and lead to increased productivity? In a field experiment with 266 employees, we find that paying higher wages, per se, does not have a discernible effect on productivity in a context with no future employment opportunities. However, structuring a portion of the wage as a clear and unexpected gift-by offering an unconditional raise after the employee has accepted the contract-leads to higher productivity for the duration of the job. Gifts are roughly as effic...

摘要:Customer impatience has become an integral component of analyzing services, especially in the context of call centers. Typically, when customers arrive to such systems, they seem identical or homogeneous; however, from the system's perspective, as they wait in the queue, their residual willingness to wait changes. For instance, a customer who has already waited for 10 minutes may have a different residual willingness to wait compared with a customer who has only waited for 1 minute. In this ma...

摘要:An extensive literature in economics and finance has documented home bias, the tendency that transactions are more likely to occur between parties in the same geographical area rather than outside. Using data from a large online crowdfunding marketplace and employing a quasi-experimental design, we find evidence that home bias still exists in this virtual marketplace for financial products. Furthermore, through a series of empirical tests, we show that rationality-based explanations cannot ful...
