  • Professional vs. amateur judgment accuracy: The case of foreign exchange rates 

    Onkal, D.; Yates, J. F.; Simga Mugan, C.; Oztin, S. (Elsevier, 2003-07)
    Highly knowledgeable people often fail to achieve highly accurate judgments, a phenomenon sometimes called the ‘‘processperformance paradox.’’ The present research tested for this paradox in foreign exchange (FX) rate ...
  • Mobility and Optimal Tenure Choice 

    Ozyildirim, S.; Onder, Z.; Yavas, A. (Elsevier, 2005-12)
    In this paper, we offer a dynamic model of the optimal tenure behavior of an individual who faces the possibility of moving multiple times during his lifetime. We also investigate the lifetime effects of such factors as ...
  • Joint economic design of EWMA control charts for mean and variance 

    Serel, D.; Moskowitz, H. (Elsevier, 2008-01-01)
    Control charts with exponentially weighted moving average (EWMA) statistics (mean and variance) are used to jointly monitor the mean and variance of a process. An EWMA cost minimization model is presented to design the ...
  • Risk and return in a Dynamic General Equilibrium Model 

    Akdeniz, L. (Elsevier, 2000-06)
    In this paper we examine the relationship between risk and return on productive assets using the intertemporal general equilibrium model of Brock (1982, Asset Prices in a Production Economy, the University of Chicago Press, ...
  • Judgemental Forecasting: A Review of Progress Over the Last 25 Years 

    Lawrence, M.; Goodwin, P.; M. O'Connor; Onkal, D. (Elsevier, 2006)
    The past 25 years has seen phenomenal growth of interest in judgemental approaches to forecasting and a significant change of attitude on the part of researchers to the role of judgement. While previously judgement was ...
  • Inventory and pricing decisions in a single-period problem involving risky supply 

    Serel, D. (Elsevier, 2008-11)
    We explore an extension of the single-period (newsboy) inventory problem when supply is uncertain. We look into the negotiations between a newsvendor (retailer) and a manufacturer when there is competition from a second ...
  • Transformational Leadership, Creativity, and Organizational Innovation 

    Gumusluoglu, L.; Ilsev, A. (Elsevier, 2009-04)
    This study proposes a model of the impact of transformational leadership both on followers' creativity at the individual level and on innovation at the organizational level. The model is tested on 163 R&D personnel and ...
  • Economic design of EWMA control charts based on loss function 

    Serel, D. (Elsevier, 2009-02)
    For monitoring the stability of a process, various control charts based on exponentially weighted moving average (EWMA) statistics have been proposed in the literature. We study the economic design of EWMA-based mean and ...
  • The Network Design Problem with Relays 

    Cabral, E. A.; Erkut, E.; Laporte, G.; Patterson, R. (Elsevier, 2007-07-16)
    The network design problem with relays (NDPR) is defined on an undirected graph G = (V,E,K), where V = {1,...,n} is a vertex set, E = {(i,j):i,j 2 V,i < j} is an edge set. The set K = {(o(k),d(k))} is a set of communication ...
  • Comments on "Effective Forecasting and Judgemental adjustments: An Empirical Evaluation and Strategies for Improvement in supply-chain planning 

    Onkal, D. (Elsevier, 2009)
    Demand forecasting is a crucial aspect of the planning process in supply-chain companies. The most common approach to forecasting demand in these companies involves the use of a computerized forecasting system to produce ...
  • A multicriteria facility location model for municipal solid waste management in North Greece 

    Erkut, E.; Karagiannidis, A.; Perkoulidis, G.; Tjandra, S. A. (Elsevier, 2008-06-16)
    Up to 2002, Hellenic Solid Waste Management (SWM) policy specified that each of the country’s 54 prefectural governments plan its own SWM system. After 2002, this authority was shifted to the country’s 13 regions entirely. ...
  • Single Item Lot Sizing Problem for a Warm/Cold Process with Immediate Lost Sales 

    Berk, E.; Toy, A. O.; Hazir, O. (Elsevier, 2008-06-16)
    We consider the dynamic lot-sizing problem with finite capacity and possible lost sales for a process that could be kept warm at a unit variable cost for the next period t + 1 only if more than a threshold value Qt has ...
  • An Extension and Further Validation of a Community-based Consumer Well-being Measure 

    Sirgy, M. J.; Lee, D.; Grzeskowiak, S.; Chebat, J. C.; Johar, J. S.; Hermann, A.; Hassan, S.; Hegazy, I.; Ekici, A.; Webb, D.; Su, C.; Montana, J. (Sage, 2008-09)
    The goal of this study is to extend the research and further validation of Lee and colleagues' measure of community-based consumer well-being. The measure is based on the notion that consumers experience well-being to the ...
  • Solving the Hazmat Transport Network Design Problem 

    Erkut, E.; Gzara, F. (Elsevier, 2008-07)
    In this paper, we consider the problem of network design for hazardous material transportation where the government designates a network, and the carriers choose the routes on the network. We model the problem as a bilevel ...
  • The Equity Premium in Brock's Asset Pricing Model 

    Akdeniz, L.; Dechert, W. D. (Elsevier, 2007-07)
    In this paper we combine dynamic programming methods with projection methods for solving stochastic growth models. As an application of these methods, we solve Brock’s asset pricing model with a variety of parameterizations. ...
  • Hazardous Materials Risk Assessment in Rail Yard Safety 

    Glickman, T. S.; Erkut, E. (Elsevier, 2007)
    This paper illustrates the application of quantitative risk assessment in a rail yard where tank cars of hazardous materials are received and stored. The assessment was conducted in response to community concerns about ...
  • Supplier diversification under binomial yield 

    Fadiloglu, M. M.; Berk, E.; Gurbuz, M. C. (Elsevier, 2008-09)
    We consider supplier diversification in an EOQ type inventory setting with multiple suppliers and binomial yields. We characterize the optimal policy for the model and show that, in this case, it does not pay to diversify, ...
  • Currency forecasting: an investigation of extrapolative judgement 

    Thomson, M. E.; Onkal Atay, D.; Pollock, A. C. (Elsevier, 1997-12)
    This paper aims to explore the potential effects of trend type, noise and forecast horizon on experts' and novices' probabilistic forecasts. The subjects made forecasts over six time horizons from simulated monthly currency ...
  • The effect of Merger Anticipation on Bidder and Target Firm Announcement Period Returns 

    Cornett, M. M.; Tanyeri, B.; Tehranian, H. (Elsevier, 2011-06)
