摘要:This paper demonstrates how increased competition entrenches dominants—a causal relationship I term durable dominance . Established theories of sustained dominance predict that a dominant’s grasp on its position weakens when resources become widely available and the number o...

摘要:The recent interest in learning from failure has led to repeated praise of failure as part of the innovation process. The challenges in detecting and terminating failing projects are, however, often underplayed. This study suggests that firms exhibit different propensities to ter...

摘要:Designing modern call centers requires an understanding of callers’ patience and abandonment behavior. Using a Cox regression analysis, we show that callers’ abandonment behavior may differ based on their contact history, and changes across their different contacts. We contr...

摘要:Let S ⊆ {0, 1} n and R be any polytope contained in [0, 1] n with R ∩ {0, 1} n = S . We prove that R has bounded Chvátal-Gomory rank (CG-rank) provided that S has bounded notch and bounded gap , where the notch is the minimum integer ...

摘要:We propose a new proximal path-following framework for a class of constrained convex problems. We consider settings where the nonlinear—and possibly nonsmooth—objective part is endowed with a proximity operator, and the constraint set is equipped with a self-concordant barri...

摘要:We examine the equity market reaction to events associated with the passage of a directive in the European Union (EU) mandating increased nonfinancial disclosure. These disclosures relate to firms’ environmental, social, and governance (ESG) performance, and would be applica...

摘要:This paper studies the optimal stopping problem in the presence of model uncertainty (ambiguity). We develop a numerically implementable method to solve this problem in a general setting, allowing for general time-consistent ambiguity-averse preferences and general payoff process...

摘要:In the past decade, we have witnessed the growing importance of management responses to online reviews on digital platforms. In this study, we examine the impact of online management responses on business performance and their spillover effect on nearby businesses. By adopting mu...

摘要:Bank lending standards vary over time. Periods in which firms find it relatively easy to borrow are followed by periods in which banks scrutinize borrowers more and tighten lending. We predict that changes in lending standards affect the accounting conservatism of bank-depen...

摘要:Sequential optimality conditions for constrained optimization are necessarily satisfied by local minimizers, independently of the fulfillment of constraint qualifications. These conditions support the employment of different stopping criteria for practical optimization algorithms...
