On the relation between the extended supporting hyperplane algorithm and Kelley’s cutting plane algorithm

Serrano, Felipe; Schwarz, Robert; Gleixner, Ambros - In: Journal of Global Optimization 78 (2020) 1, pp. 161-179

Recently, Kronqvist et al. (J Global Optim 64(2):249–272, 2016) rediscovered the supporting hyperplane algorithm of Veinott (Oper Res 15(1):147–152, 1967) and demonstrated its computational benefits for solving convex mixed integer nonlinear programs. In this paper we derive the algorithm...

Algorithmic Pricing and Competition: Empirical Evidence from the German Retail Gasoline Market

Assad, Stephanie; Clark, Robert; Ershov, Daniel; Xu, Lei - 2020

Economic theory provides ambiguous and conflicting predictions about the association between algorithmic pricing and competition. In this paper we provide the first empirical analysis of this relationship. We study Germany’s retail gasoline market where algorithmic-pricing software became...

An ethical intuitionist account of transparency of algorithms and its gradations

Hayes, Paul - In: Business Research 13 (2020) 3, pp. 849-874

To make evaluations about the morally relevant impacts of algorithms, transparency is needed. This paper lays out … discussion of algorithms and transparency in an explicitly moral analysis with a special focus on the domain of justice and … focus on algorithms in justice and security, recognising that complete transparency can be impossible where duties conflict …
