    Benchmark replication portfolio strategies
    (Palgrave Macmillan Ltd, 2013) Zolotoy, Leon; Department of Business Administration; Glabadanidis, Paskalis; Faculty Member; Department of Business Administration; College of Administrative Sciences and Economics; N/A
    We propose a novel approach to the benchmark replication problem that uses a minimum tracking error variance as an objective subject to a target expected outperformance. When no budget constraint is imposed on the replicating portfolio, the solution is a two-fund portfolio involving the standard hedge portfolio and the tangent portfolio constructed using the replicating securities. In the presence of a budget constraint, the solution is a three-fund portfolio, which includes, in addition, the minimum variance portfolio constructed using the replicating securities. We implement our theoretical results using recent data for three widely followed US stock indices with very good out-of-sample performance.

    Embarrassed by calories: joint effect of calorie posting and social context
    (The University of Chicago Press, 2022) Ceylan, Melis; Morwitz, Vicki G.; Department of Business Administration; Aydınoğlu, Nilüfer Zümrüt; Faculty Member; Department of Business Administration; College of Administrative Sciences and Economics; 114037
    Given growing health concerns about obesity, it is important to understand under what conditions calorie posting will lead to reduced caloric consumption. In one field experiment and three scenario-based studies, we show that disclosing dish-specific calorie information on a menu is more effective in lowering the total calorie of meal orders when food is ordered in the company of others. We further demonstrate that the joint effect of calorie posting and social context on food choice occurs due to anticipated embarrassment as ordering an indulgent, high-calorie meal interferes with impression management concerns in these dining contexts. Consumers order lower-calorie meals to circumvent social embarrassment. Recognizing the importance of impression management concerns during food choice, our research sheds light on previous mixed findings regarding the effectiveness of calorie posting on menus by demonstrating when and why consumers might use caloric information when making food choices.

    Embodiment of tacit knowledge as an insrument of competitive strength in the cultural markets: an example of Antakya
    (Pressacademia, 2016) Örs, Husniye; Sürmeli, Pelin; PhD Student; Graduate School of Business; N/A
    With the effects of globalization that more and more has homogenized markets, consumers have begun to prefer to experiment events they perceive differently in social, cultural, geographic, technologic etc. areas. This leaning has made local and cultural factors preferential in particular in the tourism market. The cultural factors embodied in revealing the tacit knowledge behind these factors, that are the subject of the cultural market, have become the qualities of attraction sought in cultural tourism. In this context, the aim of this research is to determine the tacit knowledge factors behind the cultural market values of Antakya which is a city existing since the Paleolithic Period to the present time and, in this way, bring these factors to the global tourism market. This research conducted with the in-depth interview method has come to the conclusion that kunefe (kunefah) making, silk weaving and laurel soap making is tacit knowledge original to the region while stone carving is tacit knowledge genuine to the individual.
