Conference Object Citation - WoS: 31Financial Innovation-Crowdfunding: Friend or Foe?(Elsevier, 2015) Son-Turan, SemenA phenomenon with a considerable past, and with new conspicuous investment models and financial products and servicesproliferated through the Internet; financial innovation seems to be almost ubiquitous these days. While there are numerousadvantages, especially nowadays through the exploitation of easily accessible, low cost and convenient e-commerce platforms,innovation in the finance sector does not come without its perils. Banks and traditional financial institutions are losing chunks ofmarket share to virtual intermediaries and investors are operating in relatively less regulated and, consequently, less secureenvironments. Furthermore, from the perspective of all stakeholders, there is a Knightian uncertainty component of the long-termramifications in investing in and through newly developed products and platforms. As such, it is only recently that economichistory witnessed the outbreak of the sub-prime mortgage crisis caused by the unraveling of a chain of events interlinked throughthe imprudent use of “innovative” derivative transactions involving credit default swaps backed by the insatiable appetite of the“irrationally exuberant” investor and the easement of regulation paving the leeway for predatory lending. This paper investigateswhether and to what extent innovative investment models such as crowdfunding, as the game-changer, forcing the tightlyregulated securities markets to adapt to the rules of the WEB 3.0 era and relieved through the provision, Title III, of the JOBSAct, could be a potential peril. To that end, it discusses the evolution of the equity crowdfunding model in the realm of thetechnology push - demand pull framework and analyzes the current situation of the market.Article Citation - WoS: 49Citation - Scopus: 70Locus of Control, Need for Achievement, and Entrepreneurial Intention: a Moderated Mediation Model(Elsevier, 2021) Tuncer, Büşra; Uysal, Şenay Karakuş; Şahin, Faruk; Karadağ, HandeApplying social cognitive career theory (Lent, Brown, & Hackett, 2002) to entrepreneurship, this paper addresses the effects of locus of control and need for achievement on entrepreneurial intentions, and whether the effects are mediated by entrepreneurial self-efficacy and vary according to sex. The participants were 111 students enrolled in the business administration program in Turkey. Using longitudinal survey data, the research model was tested with the moderated mediation procedure suggested by Hayes (2013). The findings showed that entrepreneurial self-efficacy mediated the relationship between locus of control and entrepreneurial intention, as well as the relationship between need for achievement and entrepreneurial intention. Moreover, the conditional indirect analysis showed that the effect of locus of control on entrepreneurial intention depended on sex, with the effect of locus of control being greater for men. By showing empirical evidence for the usefulness of social cognitive career theory to entrepreneurship, our research adds to current literature. Implications for practice and recommendations for future research are discussed.Article Citation - WoS: 6Citation - Scopus: 16Minimum Cost Delivery of Multi-Item Orders in E-Commerce Logistics(Elsevier, 2022) Muter, İbrahim; Laportece, GilberT; Akyüz, M. Hakan; Erdoğan, GüneşWe solve a delivery problem arising in e-commerce logistics. We consider a retailer with an online store and a network of stores operating in an omni-channel strategy. The fulfillment decision for an online order, which contains a number of items, involves the allocation of these items to the stores where they are available and the selection of one store for consolidation of the items into the final package to be dispatched to the customer. The transportation between the stores and the customer is handled by a third-party logistic provider which uses a concave pricing policy based on the distance between the origin and the destination, as well as on the weight of the items. We present an online problem which is defined for a set of orders placed over time, and a mixed integer programming formulation defined for each order. The main characteristics of this problem are that the solution of the formulation for each order impacts those of the subsequent orders, and the problem must be solved in real time. For the solution of the formulation, we propose an iterative matheuristic based on the solution of the set covering model and local search. Computational results on randomly generated instances are provided, which demonstrate that our algorithm is capable of producing high-quality results.Article Citation - Scopus: 3The Ethical Shortlisting Problem(Elsevier, 2021) Erdoğan, GüneşHiring is a fundamental, frequent activity for all organizations. Hiring decisions have been reported to be subject to conscious and unconscious biases in the literature. The field of Computational Ethics aims to quantify and maximize the ethicality of decisions. This paper attempts to apply Computational Ethics to the shortlisting process in hiring through the use of Linear Programming. Given a set of applicants for a job with numerical qualification values, the author aims to determine weights for each qualification type to compute scores and resulting rankings for each applicant. To this end, Abstract Moral Theories of Utilitarianism, Maximin/Leximin, Egalitarianism, and Prioritarianism are utilized and applied to a set of randomly generated applicant data. Computational experiments demonstrate that the models are scalable and return interpretable results. The necessity of a quota-based shortlisting system to alleviate disadvantaged candidates is highlighted. The author recommends the use of the Maximin model and iteratively eliminating the applicant with the lowest score.
