New Sources of Development Finance: Funding the Millennium Development Goals
Mobilizing additional finance to meet the challenges of the Millennium Development Goals (MDGs) is an urgent priority. Developing countries are mobilizing resources themselves to meet the MDG targets by 2015, but they will fall short without additional external flows. Increased private and public money is needed in order for the world's poorest countries to invest in the basic services and infrastructure necessary for human development, and to improve livelihoods and employment for poor people.As a result of the Five Year Review of the World Summit for Social Development, the UN General Assembly in September 2000 adopted a resolution calling for 'a rigorous analysis of the advantages, disadvantages and other implications of proposals for developing new and innovative sources of funding, both public and private, for dedication to social development and poverty eradication programmes'. The UN Department of Economic and Social Affairs in turn requested the World Institute for Development Economics Research (UNU-WIDER) in Helsinki to undertake a project on 'Innovative Sources for Development Finance'. This Policy Brief summarizes the key findings of the study carried out by UNUWIDER. Anthony B. Atkinson, Project Director and Warden of Nuffield College, University of Oxford, has written the Policy Brief drawing on the papers prepared for the project. He acknowledges the substantial contribution made by the project authors, but takes full responsibility for the opinions expressed
Income Tax and Top Incomes over the Twentieth Century
The first section of the paper gives a stylised account of the development of the UK income tax structure over the past 200 years, and refers to recent changes in other OECD countries. The second section turns to the distribution of income and summarises the evidence about the top of the income distribution that can be derived from the income tax data. The main results relate to the UK, but comparisons are made with similar evidence for Canada, France, the Netherlands, and the US. The third part of the paper considers the explanation of the observed changes in the distribution and the impact of progressive income taxation. How far are changes in income shares a reflection of the re-arrangement of income? How far are they associated with changes in the composition of top incomes? Conclusions about distributional incidence have to be based on modelling the determination of the personal income distribution, but such modelling is not typically treated in public finance textbooks. The fourth section of the paper considers how the analysis of distributional incidence can be developed, paying specific attention to the explanation of the upper tail of the distribution. : Income, Taxation, Income Distribution, Tax Incidence
SERS Detection of Graphene Oxide in Acid Catalyzed Sol-Gels
Silica sol-gel and aerogel substrates were synthesized using a modified acid catalyzed hydrolysis of tetramethyl orthosilicate method that incorporated graphene oxide and silver nanoparticles into the matrix. The effectiveness of loading of graphene oxide was monitored by UV-vis and surface enhanced Raman spectroscopy (SERS). Characterization data suggests that graphene oxide is detectable through SERS while integrated into a sol-gel and that size of silver nanoparticles has an impact on the SERS spectrum of graphene oxide
