Regional distribution of photovoltaic deployment in the UK and its determinants: A spatial econometric approach
Photovoltaic (PV) panels offer significant potential for contributing to the UK's energy policy goals relating to decarbonisation of the energy system, security of supply and affordability. The substantive drop in the cost of panels since 2007, coupled with the introduction of the Feed-in Tariff (FiT) Scheme in 2010, has resulted in a rapid increase in installation of PV panels in the UK, from 26.5MWp in 2009 to over 5GW by the end of 2014. Yet there has been no comprehensive analysis of the determinants of PV deployment in the UK. This paper addresses this gap by employing spatial econometrics methods to a recently available data set at a fine geographical detail. Following a traditional regression analysis, a general to specific approach has been adopted where spatial variations in the relationships have been examined utilising the spatial Durbin model using the cross-sectional data relating to the UK NUTS level 3 data. Empirical results indicate that demand for electricity, population density, pollution levels, education level of households and housing types are among the factors that affect PV uptake in a region. Moreover Lagrange Multiplier test results indicate that the spatial Durbin model may be properly applied to describe the PV uptake relationship in the UK as there are significant regional spillover effects
The experience with macro-prudential policies of the central bank of the republic of Turkey in response to the global financial crisis
This brief country case study on Turkey aims to summarize the fundamental developments in the banking sector, which represents almost 90 percent of the financial sector in the country. The brief has two parts. The first covers the 2001 financial crisis and the developments until end of 2007, the year before the global financial crisis of 2008 started. The second part focuses on the macro-prudential policies applied by the Central Bank of the Republic of Turkey in response to the global financial crisis in three phases: (i) full liquidity support after Lehman Brothers'collapse (September 2008), (ii) the exit strategy (April 2010), and (iii) the new policy mix (final quarter of 2010).Debt Markets,Banks&Banking Reform,Currencies and Exchange Rates,Emerging Markets,Bankruptcy and Resolution of Financial Distress
Magnetic Structure and Spin Waves in the Kagom\'{e} Jarosite compound
We present a detailed study of the magnetic structure and spin waves in the
Fe jarosite compound for the most general
Hamiltonian involving one- and two-spin interactions which are allowed by
symmetry. We compare the calculated spin-wave spectrum with the recent neutron
scattering data of Matan {\it et al.} for various model Hamiltonians which
include, in addition to isotropic Heisenberg exchange interactions between
nearest () and next-nearest () neighbors, single ion anisotropy and
Dzyaloshinskii-Moriya (DM) interactions. We concluded that DM interactions are
the dominant anisotropic interaction, which not only fits all the splittings in
the spin-wave spectrum but also reproduces the small canting of the spins out
of the Kagom\'e plane. A brief discussion of how representation theory
restricts the allowed magnetic structure is also given.Comment: 23 pages, 17 figures, submitted to Phys. Rev. B (March 2006
