Yayın Dilemma of the HR manager: An optimization for training and development budgets using integer programming a case study from an international firm(Int Inst Informatics & Systemics, 2005) Yanık, Serhat; Yazıcı, Selim; Şenel, İlhan KeremThis paper is about a dilemma of an HR manager of an international company. The major problem of HR managers is to minimize their training and development budgets. Making a training budget is not so complex; but the important, yet often neglected, part of budgeting is the costs of absence of employees. In every kind of training, whether traditional or e-learning, there is a cost for the time being spent away from work. Some of the managers think that this is an idle time for company, plus the employee is paid during this period. This paper focuses on the costs of the absence and their effect on training budgets. Some scenarios were developed with the help of an HR manager of an international firm. The feasibility of these scenarios was studied by using integer programming.Yayın On the performance of West's bubble test: A simulation approach(Elsevier science inc, 2010-12-01) Yüksel, Sadettin Aydın; Akdeniz, Levent; Altay Salih, AslıhanIn this research we examine the ability of West's bubble test [1] in detecting speculative bubbles using Brock's (1982) [2] intertemporal general equilibrium model of asset pricing as the basis for a simulation study. In this setting, (1) the economy, by construction is efficient and produces the maximally possible amount of welfare for society, and (2) asset prices reflect the utility-maximizing behavior of consumers and the profit-maximizing behavior of firms. We find that the West's bubble test flag as "bubbles" in the simulated data yet the data is produced from an economy in which markets are efficient in welfare production.
