Publication Metadata only Approaches to the measurement and management of customer value(Taylor & Francis, 2006) Keiningham, T.L.; Bejou, D.; Department of Business Administration; Aksoy, Lerzan; Faculty Member; Department of Business Administration; College of Administrative Sciences and Economics; N/ADetermining and managing customer lifetime value is one of the most important strategic objectives of companies today. This paper critically examines some of the most popular approaches traditionally used to measure the value of customers in a company's portfolio. The methods reviewed include RFM and total revenue approaches to differentiating the value of customers. Although these methods have relative advantages, they have serious drawbacks that limit the ability of managers to accurately assess customer value. An alternative model for the measurement and management of customer value is proposed.Publication Metadata only Bank lending standards and access to lines of credit(Wiley, 2012) James, Christopher; Kizilaslan, Atay; Department of Business Administration; Demiroğlu, Cem; Faculty Member; Department of Business Administration; College of Administrative Sciences and Economics; 18073This paper examines how changes in bank lending standards are related to the availability of bank lines of credit for private and comparable public firms. Overall, we find that access to lines of credit is more contingent on bank lending standards for private than for public firms. The impact of bank lending standards is however asymmetric: while private firms are less likely than public firms to gain access to new lines when credit market conditions are tight, we find no difference between public and private firms in terms of their use or retention of pre-existing lines. We also find that private firms without lines of credit use more trade credit when bank lending standards are tight, which is suggestive of a supply effect. Overall, the evidence suggests that credit crunches are likely to have a disproportionate impact on private firms. However, pre-existing banking relationships appear to mitigate the impact of these contractions on private firms.Publication Metadata only Bank loans and troubled debt restructurings(Elsevier Science Sa, 2015) James, Christopher; Department of Business Administration; Demiroğlu, Cem; Faculty Member; Department of Business Administration; College of Administrative Sciences and Economics; 18073This paper examines the relation between the number and type of lenders that participate in corporate loan facilities and the nature of troubled debt restructurings. We find that loans from traditional bank lenders are significantly easier to restructure out of court than loans from institutional lenders. We also find that the existence of a past banking relationship between the borrower and the lead arranger of a syndicated loan adversely affects the ease of restructuring. Finally, we find that reliance on loans that are held in part by collateralized loan obligations (CLOs) is positively related to the likelihood of a prepackaged bankruptcy, consistent with greater holdout problems when loans are held by CLOs. Overall, our findings suggest that the role of banks in the restructuring process is quite different when bank loans are diffusely held or securitized. (C) 2015 Elsevier B.V.

M.; Department of Business Administration; Tunalı, Ayşegül Özsomer; Department of Business Administration; College of Administrative Sciences and EconomicsN/APublication Open Access Can the desired service level be achieved when the demand and lost sales are unobserved?(Institute of Electrical and Electronics Engineers (IEEE), 2002) Department of Business Administration; Tan, Barış; Karabatı, Selçuk; Faculty Member; Faculty Member; Department of Business Administration; College of Administrative Sciences and Economics; 28600; 38819In this paper we consider an inventory management problem in the retail industry with unobserved lost sales. The retailer does not know the demand for a particular product but she has access to Point-Of-Sale (POS) data. The retailer uses a fixed review period, order-up-to level system to control the inventory. The objective of the retailer is to achieve a pre-specified service level. We define the service level as the fraction of demand satisfied from inventory. However, due to the unobserved lost sales nature of the problem, the retailer cannot exactly measure the current service level. We propose a POS data-based mechanism for periodic updating of the order-up-to level. We show that the periodic updating approach yields the desired service level without using any inventory information. Once the periodic updating scheme converges, it also gives the actual demand distribution.Publication Metadata only Crash risk and conservatism: Evidence from Borsa Istanbul(Elsevier, 2024) Department of Business Administration; Toksöz, Tuba; Department of Business Administration; College of Administrative Sciences and EconomicsThis study assesses the relationship between the likelihood of future stock price crashes and conservatism-an accounting characteristic that leads to the undervaluation of accounting net assets relative to economic net assets. This undervaluation is achieved by less stringent verification criteria in acknowledging losses compared with gains, resulting in more timely recognition of economic losses. Utilizing a sample of firms traded on Borsa Istanbul from 2009 to 2019, this study reveals that firms with a greater degree of conservatism witness a significant reduction in crash risk after accounting for firm-specific determinants of crash risk along with firm and year fixed effects. This result corroborates the findings in the literature on conservatism, revealing that conservatism diminishes the ability of managers to withhold unfavorable information. In addition, the results are economically meaningful and hold after a set of tests to assess robustness. The findings are particularly relevant for underperforming firms, indicating that an increase in adverse information enhances the motivation for firms to obscure and delay sharing the information. Further analysis demonstrates that accounting conservatism offers advantages by mitigating future crash risk, especially for firms with high intangible intensity.Publication Metadata only Creating a functioning European Union(Palgrave, 2011) Department of Business Administration; Akdeniz, Özlem Olgu; Teaching Faculty; Department of Business Administration; College of Administrative Sciences and Economics; 113156Publication Open Access Cyclical dynamics of industrial production and employment: Markov chain-based estimates and tests(Elsevier, 2012) Gencer, Gözde; Department of Business Administration; Tan, Barış; Altuğ, Sumru; Faculty Member; Faculty Member; Department of Business Administration; College of Administrative Sciences and Economics; 28600; N/AThe purpose of this paper is to understand differences in cyclical phenomena across a broad range of developed and emerging countries based on the behavior of two key economic times series—industrial production and employment. The paper characterizes the series in question as a recurring Markov chain. Univariate processes are estimated for each series individually, and a composite indicator is constructed by using information on both series. Based on tests of equality of the estimated Markov chains across countries as well as the expected times to switch between different states, we find evidence that (i) the developed and emerging economies are “de-coupled” from each other in terms of their cyclical dynamics, and (ii) the behavior of industrial production and employment growth are “de-coupled” for the emerging economies. Our results suggest new directions for the analysis of emerging economy cyclical fluctuations.Publication Metadata only Do market prices improve the accuracy of court valuations in chapter 11?(Wiley, 2022) Franks, Julian; Lewis, Ryan; Department of Business Administration; Demiroğlu, Cem; Faculty Member; Department of Business Administration; College of Administrative Sciences and Economics; 18073The average difference between the court value and postemergence market value of newly issued stocks in Chapter 11 reorganizations exceeds 50%. We show that public dissemination of transactions in defaulted bonds reduces this difference by 23% and largely eliminates interclaimant wealth transfers. The effects of dissemination are only significant when the bonds are sufficiently traded around the court valuation date and when they receive significant amounts of postemergence equity, indicating that the bond's value is sensitive to the size and allocation of the pie. These findings imply that security prices have real effects: they improve the valuations of bankruptcy participants.Publication Open Access Do physiological and spiritual factors affect economic decisions?(Wiley, 2021) Özbaş, Oğuzhan; Silva, Rui C.; Department of Business Administration; Demiroğlu, Cem; Ulu, Mehmet Fatih; Faculty Member; Faculty Member; Department of Business Administration; College of Administrative Sciences and Economics; 18073; N/AWe examine the effects of physiology and spiritual sentiment on economic decision-making in the context of Ramadan, an entire lunar month of daily fasting and increased spiritual reflection in the Muslim faith. Using an administrative data set of bank loans originated in Turkey during 2003 to 2013, we find that small business loans originated during Ramadan are 15% more likely to default within two years of origination. Loans originated in hot Ramadans, when adverse physiological effects of fasting are greatest, and those approved by the busiest bank branches perform worse. Despite their worse performance, Ramadan loans have lower credit spreads.
