  • Role of Strong versus Weak Networks in Small Business Growth in an Emerging Economy 

    Kozan, M. K.; Akdeniz, L. (MDPI, 2014-02)
    The study tests whether strong rather than weak ties account for small business growth in Turkey. Data were collected by means of a questionnaire filled out by the owners of small firms operating in four cities. Growth ...
  • Robust optimization models for the dicrete time/cost trade-off problem 

    Hazir, O.; Erel, E.; Gunalay, Y. (Elsevier, 2011-03)
    Developing models and algorithms to generate robust project schedules that are less sensitive to disturbances are essential in today’s highly competitive uncertain project environments. This paper addresses robust ...
  • Does Backing Up Behavior Explain the Efficacy-Performance Relationship in Teams? 

    Porter, C. O. L. H.; Gogus, I.; Yu, R. C. F. (Sage, 2011-02-28)
    Although the relationship between collective efficacy beliefs and team performance has been well-documented, few studies have explored the causal mechanisms that might explain these effects. In the current study, the authors ...
  • Stock-market reactions to mergers of non-financial Turkish firms 

    Hekimoglu, M. H.; Tanyeri, B. (IIF, 2011-02-23)
    This paper investigates stock-market reactions to mergers and partial sales of non-financial Turkish firms. Turkish targets earn average cumulative abnormal returns (CAR) of 8.56 percent in the three-day window around ...
  • The Equity Premium in Consumption and Production Models? 

    Akdeniz, L.; Dechert, W. D. (Cambridge University Press, 2012-02-27)
    In this paper we use a simple model with a single Cobb–Douglas firm and a consumer with a CRRA utility function to show the difference between the equity premia in the production-based Brock model and the consumption-based ...
  • 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 ...
  • 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 ...
  • 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 ...
  • On the statistical Analysis of Feigenbaum Constants 

    Sezgin, F.; Sezgin, T. M. (Elsevier, 2006-11)
    We present statistical analysis of blocks in the binary expansions of Feigenbaum constants a and d for the logistic map. The analysis is carried out on both 1016 and 3400 bit expansions. A w2 test is applied for lumping ...
  • On pricing of perishable assets with menu costs 

    Berk, E.; Gurler, U.; Yildirim, G. (Elsevier, 2009-10)
    We consider dynamic pricing of perishable assets in the presence of price-sensitive renewal demand processes. Unlike the existing works in the literature, we explicitly incorporate non-negligible price change costs which ...
  • Optimal ordering and pricing in a quick response system 

    Serel, D. (Elsevier, 2009-10)
    Quick response systems enable retailers to estimate customer demand more accurately, and improve stocking decisions for perishable products with uncertain demand. Retailers place separate orders for a product at two different ...
  • Ant colony optimization for the single model U-type assembly line balancing problem 

    Sabuncuoglu, I.; Erel, E.; Alp, A. (Elsevier, 2009-08)
    An assembly line is a production line in which units move continuously through a sequence of stations. The assembly line balancing problem is defined as the allocation of tasks to an ordered sequence of stations subject ...
  • The dynamic lot-sizing problem with convex economic production costs and setups 

    Kian, R.; Gurler, U.; Berk, E. (Elsevier, 2014-09)
    In this work the uncapacitated dynamic lot-sizing problem is considered. Demands are deterministic and production costs consist of convex costs that arise from economic production functions plus set-up costs. We formulate ...
  • Pricing and revenue management: The value of coordination 

    Kocabiyikoglu, A.; Popescu, I.; Stefanescu, C. (INFORMS, 2014)
    The integration of systems for pricing and revenue management must trade off potential revenue gains against significant practical and technical challenges. This dilemma motivates us to investigate the value of coordinating ...
  • The influence of early efficacy beliefs on teams' reactions to failing to reach performance goals 

    Porter, C. O. L. H.; Gogus, I.; Yu, R. C. F. (Blackwell Publishing Ltd, 2011)
    Although a considerable amount of theoretical and empirical attention has been devoted to understanding individuals' responses to goal–performance discrepancies (GPDs), little attention has been devoted to examining how ...
  • Researching Islamic Marketing: Past and Future Perspectives 

    Sandikci, O. (Emerald Group Publishing Limited, 2011)
    Purpose: The purpose of this paper is to explore the reasons underlying the recent interest on Islamic marketing, discusses past research on the topic and offers a future research perspective. Design/methodology/approach: ...
  • Multicriteria inventory classification using a genetic algorithm 

    Guvenir, H. A.; Erel, E. (Elsevier, 1998-02-16)
    One of the application areas of genetic algorithms is parameter optimization. This paper addresses the problem of optimizing a set of parameters that represent the weights of criteria, where the sum of all weights is 1. ...
  • Computational aspects of the maximum diversity problems 

    Ghosh, J. B. (Elsevier, 1996-10)
    We address two variations of the maximum diversity problem which arises when m elements are to be selected from an n-element population based on inter-element distances. We study problem complexity and propose randomized ...
  • Expected gain-loss pricing and hedging of contingent claims in incomplete markets by linear programming 

    Pinar, M. C.; Salih, A.; Camci, A. (Elsevier, 2010-03-16)
    We analyze the problem of pricing and hedging contingent claims in the multi-period, discrete time, discrete state case using the concept of a ‘‘k gain–loss ratio opportunity”. Pricing results somewhat different from, ...
  • 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. ...
