    Good Countries or Good Projects?: Comparing Macro and Micro Correlates of World Bank and Asian Development Bank Project Performance
    (World Bank, Washington, DC, 2015-04) Bulman, David; Kolkma, Walter; Kraay, Aart
    This paper examines the micro and macro correlates of aid project outcomes in a sample of 3,821 World Bank projects and 1,342 Asian Development Bank projects. Project outcomes vary much more within countries than between countries: country-level characteristics explain only 10–25 percent of project outcomes. Among macro variables, country growth and the policy environment are significantly positively correlated with project outcomes. Among micro variables, shorter project duration and the presence of additional financing are significantly correlated with better project outcomes. In addition, the track record of the project manager in delivering successful projects is highly significantly correlated with project outcomes. There are few significant differences between the two institutions in the relationship between these variables and project outcomes.

    Growth in China 1978-2008 : Factor Accumulation, Factor Reallocation, and Improvements in Productivity
    (World Bank, Washington, DC, 2011-05-17) Bulman, David; Kraay, Aart
    China's economic success over the past three decades can be decomposed into three broad contributions to growth; accumulation of labor and capital, growth induced by structural transformation (i.e. the reallocation of labor and capital across sectors and ownership units), and growth in total factor productivity. Understanding the evolution of these three growth determinants is important for understanding China s future growth potential. For example, in the neoclassical growth model, rapid growth through factor accumulation eventually slows with the onset of diminishing returns. And growth achieved through the reallocation of factors of production from less efficient to more efficient uses will also eventually peter out as marginal products of factors are equated across units. In this paper we perform a growth accounting exercise for China which allows us to separate these three broad contributions to growth. The main novelty of our exercise lies in our efforts to understand the role of reallocation of both capital and labor across major sectors (agriculture, industry, and services), and across ownership forms (state, collective, and other).
