• Online Learning via Offline Greedy Algorithms: Applications in Market Design and Optimization AI翻译

  摘要：Motivated by online decision making in time-varying combinatorial environments, we study the problemof transforming offline algorithms to their online counterparts. We focus on offline combinatorial problems that are amenable to a constant factor approximation using a greedy algorithm that is robust to local errors. For such problems, we provide a general framework that efficiently transforms offline robust greedy algorithms to online ones using Blackwell approachability. We show that the resu...
• Disclosure Substitution AI翻译

  摘要：This study develops and tests a simple model of voluntary disclosure in which managers can choose to withhold (i.e., redact) certain elements from mandatory disclosure. We consider a setting in which mandatory disclosure is a disaggregated disclosure (e.g., a financial statement), voluntary disclosure is an aggregate disclosure (e.g., an earnings forecast), and the costs of each type of disclosure are distinct. In this setting, we showthatmanagers endogenously substitute between the two types ...
• The Bright Side of Inequity Aversion AI翻译

  摘要：Modern consumers are concerned about not only their material payoff, but also the fairness of the transaction when making purchasing decisions. In this paper, we investigate how consumers' inequity aversion affects a manufacturer who sources inputs from upstreamsuppliers. We find that, when the manufacturer sources from a single supplier or when consumers observe the manufacturer's cost, inequity aversion hurts both the supplier's and manufacturer's profits. However, when the manufacturer sour...
• Network Effects and Multinetwork Sellers' Dynamic Pricing in the US Smartphone Market AI翻译

  摘要：Although the literature on network effects has focused on single-network firms, many industries feature multinetwork firms that play more complex dynamic pricing games. In this paper, we estimate the network effect at the smartphone operating system (OS) level and study multi-OS telecommunication carriers' dynamic pricing strategies in an oligopolistic setting, using data on the U.S. smartphone industry. We find a positive OS network effect. Counterfactual analysis indicates that if the carrie...
• Managerial Duties and Managerial Biases AI翻译

  摘要：Much of the evidence on managerial biases in corporate finance focuses on the CEO and, in particular, CEO overconfidence. This singular focus can lead to misattribution as it ignores the roles of other managers who are responsible for a given corporate outcome. We evaluate the influence of the CFO and other C-suite executives as compared with the CEO. Mirroring the widely used Longholder CEO measure of CEO overconfidence, we construct Longholder CFO and Longholder Other measures. For financing...
• Manufacturing and Regulatory Barriers to Generic Drug Competition: A Structural Model Approach AI翻译

  摘要：Understanding the drivers of market concentration in the generic pharmaceutical industry is essential to guaranteeing the availability of low-cost generics. In this paper, we develop a structural model to capture the multiple determinants governing manufacturers' entry decisions; in particular, we focus on how manufacturing complexity and the regulatory environment for generics approval affect concentration in drug markets. We estimate the model using data collated from six disparate sources. ...
• Shareholder Short-Termism, Corporate Control and Voluntary Disclosure AI翻译
  作者：Jia, Xue; Menon, Rahul

  摘要：This paper examines how a manager uses voluntary disclosure to influence corporate control by a short-term shareholder. Because a short-term shareholder intervenes excessively, the manager's disclosure strategy is determined by the trade-off between excessive and insufficient intervention. In equilibrium, when shareholder short-termism is not too high, the manager discloses both good and bad news and withholds intermediate news. Alternatively, when shareholder short-termism is high, the manage...
• Is Price Commitment a Better Solution to Control Carbon Emissions and Promote Technology Investment? AI翻译

  摘要：Recent years have seen considerable debate about the practicability of a global quantity/price commitment to control carbon emissions and tackle environmental issues. In this paper, we study the impact of the cap-and-trade policy (quantity commitment) and the carbon tax policy (price commitment) on a firm's technology investment and production decisions. The main feature captured in our model is that there exist correlated uncertainties between the sales market (demand uncertainty) and the per...
• Stockpiling at the Onset of the COVID-19 Pandemic: An Empirical Analysis of National Prescription Drug Sales and Prices AI翻译

  摘要：At the onset of the coronavirus (COVID-19) pandemic, hospitals experienced a demand surge for COVID-19-related medical care while simultaneously struggling to source prescription drugs needed to manage COVID-19 patients. This is worrisome as shortfalls in the supply of essential drugs can negatively impact patient outcomes. The popular press reporting on these challenges suggests that they are caused by supply chain disruptions. However, rigorous research on the relationship between the pandem...

  摘要：There is growing agreement among researchers and developers that in certain machine-learning (ML) tasks, it may be advantageous to keep a human in the loop rather than rely on fully autonomous systems. Continual human involvement can mitigate machine bias and performance deterioration while enabling humans to continue learning from insights derived by ML. Yet a microlevel theory that effectively facilitates joint and continual learning in both humans and machines is still lacking. To address t...
