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:In this paper, we develop a risk-averse two-stage stochastic program (RTSP) that explicitly incorporates the distributional ambiguity covering both discrete and continuous distributions. We formulate RTSP from the perspective of distributional robustness by hedging against t...

摘要:We formulate the merchant trading of energy in a network of storage and transport assets as a Markov decision process with uncertain energy prices, generalizing known models. Because of the intractability of our model, we develop heuristics and both lower and dual (upper) bounds ...

摘要:We study a supply chain where a retailer buys from a supplier who faces financial constraints. Informational problems about the supplier’s demand prospects and production capabilities restrict her access to capital. By committing to a minimum purchase quantity, the retailer ...

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...
