    • First-principles study of GaAs nanowires 

      Cahangirov, S.; Çıracı, Salim (American Physical Society, 2009)
      In this paper we present a detailed analysis of the atomic and electronic structures of GaAs nanowires using first-principles pseudopotential calculations. We consider six different types of nanowires with different diameters ...
    • First-principles study of superlow friction between hydrogenated diamond surfaces 

      Çıracı, Salim; Dağ, Sefa (ASME, 2005)
      Attractive interaction between two clean diamond(001) slabs turns repulsive upon the hydrogenation of surfaces. Even under high loading forces, this repulsive interaction prevents the sliding surfaces from being closer to ...

      Aktürk, E.; Çıracı, Salim (American Physical Society, 2009)
      This paper presents our study on the atomic, electronic, magnetic structures, and phonon modes of the low-temperature orthorhombic phase of undoped BaFe2As2 crystal. The electronic structure is characterized by a sharp ...
    • A First-principles Study of the Structure and Dynamics of C8H8, Si8H8, and Ge8H8 Molecules 

      Kiliç, Ç.; Yildirim, T.; Mehrez, H.; Çıracı, Salim (American Chemical Society, 2000)
      We present a first-principles study to elucidate the nature of the bonding, stability, energetics, and dynamics of individual X8H8 molecules (X = C, Si, Ge). The results obtained from both "local basis" and "pseudopotential" ...
    • First-principles study of thin TiOx and bulklike rutile nanowires 

      Çakır, D.; Gülseren, O. (American Physical Society, 2009)
      We have systematically investigated structural, electronic and magnetic properties of very thin TiOx (x=1,2) nanowires as well as bulklike (110) rutile nanowires by using the first-principles plane-wave pseudopotential ...
    • First-principles study of two-and one-dimensional honeycomb structures of boron nitride 

      Topsakal, M.; Aktürk, E.; Çıracı, Salim (American Physical Society, 2009)
      This paper presents a systematic study of two- and one-dimensional honeycomb structures of boron nitride BN using first-principles plane-wave method. In order to reveal dimensionality effects, a brief study of all allotropic ...
    • First-principles study of zinc oxide honeycomb structures 

      Topsakal, M.; Cahangirov, S.; Bekaroglu, E.; Çıracı, Salim (American Physical Society, 2009)
      We present a first-principles study of the atomic, electronic, and magnetic properties of two-dimensional 2D, single and bilayer ZnO in honeycomb structure and its armchair and zigzag nanoribbons. In order to reveal the ...
    • Fiscal convergence in the European Union 

      Kocenda, E.; Kutan, A. M.; Yigit, T. M. (Elsevier BV, 2008)
      We empirically examine the fiscal convergence of the recent ten European Union (EU) members using the Maastricht fiscal convergence criteria. We test for absolute beta and sigma convergence of the new members in comparison ...
    • Fiscal debt management, accumulation and transitional dynamics in a CGE model for Turkey 

      Diao, X.; Roe, T. L.; Yeldan, A. E. (Routledge, 1998)
      We use a dynamic general equilibrium model based on intertemporally optimizing agents to study alternative debt management policies for the Turkish economy. The model is based on the neoclassical growth theory in its ...
    • Fiscal decentralization : a political economy approach 

      Aslım, Erkmen Giray (Bilkent University, 2013)
      This study presents a theoretical approach to analyze income and welfare implications of fiscal decentralization in a static closed economy model where political factors are taken into account. We provide two alternative ...
    • Fiscal decentralization and deficits: international evidence 

      Neyapti, B. (Elsevier BV, 2010)
      This paper investigates macroeconomic effects of fiscal decentralization, which has been a neglected area of research. Panel evidence for 16 countries over 1980-1998 indicates that expenditure and revenue decentralization ...
    • Fiscal decentralization and fiscal discipline 

      Çakır, Nida (Bilkent University, 2006)
      In this thesis, the effects of fiscal procedures, fiscal centralization and fiscal decentralization, on fiscal discipline are analyzed in a theoretical framework. A model of two optimization problems is established: ...
    • Fiscal decentralization and its effects on macroeconomic performance 

      Yalım, Derya (Bilkent University, 2003)
      Decentralization has become an important policy issue in recent years. International organizations allocate more space for fiscal decentralization in their agenda. In the literature, there are vast amount of studies that ...
    • Fiscal decentralization in Turkey: an empirical assessment of the transfer rule 

      Özdemir, Begüm (Bilkent University, 2018-07)
      This thesis analyzes whether the fiscal relations between the central and local governments of Turkey can be solely explained by socio-economic and demographic factors or the regional and political positions of cities ...
    • Fiscal decentralization, central bank independence and inflation: a panel investigation 

      Neyapti, B. (Elsevier BV, 2004)
      We reinvestigate the relationship between revenue decentralization (RD), central bank independence (CBI) and inflation by modifying the paper by (ECO 72 (2001) 95). We show that, in contrast to the earlier findings, RD has ...
    • Fiscal decentralization, fiscal rules and fiscal discipline 

      Neyapti, B. (Elsevier, 2013)
