Ankara : The Department of Economics and the Institute of Economics and Social Sciences of Bilkent University, 2008.Thesis (Master's) -- Bilkent University, 2008.Includes bibliographical refences.In this thesis, we analyzed the existence of cycles `a la Poincar´e-AndronovHopf
in optimal growth models with time delay. The analysis builds upon
a new method developed, which investigates the number of pure imaginary
roots of the characteristic equation. The method was applied to the time-tobuild
models of Asea and Zak (1999) and Winkler (2004).Yüksel, Mustafa KeremM.S
