Abstract
Under the Kyoto Protocol, industrial
countries accept caps on their emissions of greenhouse
gases. They are permitted to acquire offsetting emissions
reductions from developing countries - which do not have
emissions limitations - to assist in complying with these
caps. Because these emissions reductions are defined against
a hypothetical baseline, practical issues arise in ensuring
that the reductions are genuine. Forestry-related emissions
reduction projects are often thought to present greater
difficulties in measurement and implementation, than
energy-related emissions reduction projects. The author
discusses how project characteristics affect the process for
determining compliance with each of the criteria for
qualifying. Those criteria are: 1) Additionality. Would
these emissions reductions not have taken place without the
project? 2) Baseline and systems boundaries (leakage). What
would business-as-usual emissions have been without the
project? And in this comparison, how broad should spatial,
and temporal system boundaries be? 3) Measurement (or
sequestration). How accurately can we measure actual
with-project emissions levels? 4) Duration or permanence.
Will the project have an enduring mitigating effect? 5)
Local impact. Will the project benefit its neighbors? For
all the criteria except permanence, it is difficult to find
generic distinctions between land use change and forestry
and energy projects, since both categories comprise diverse
project types. The important distinctions among projects
have to do with such things as: a) The level and
distribution of the project's direct financial
benefits. b) How much the project is integrated with the
larger system. c) The project components' internal
homogeneity and geographic dispersion. d) The local
replicability of project technologies. Permanence is an
issue specific to land use and forestry projects. The author
describes various approaches to ensure permanence, or adjust
credits for duration: the ton-year approach (focusing on the
benefits from deferring climatic damage, and rewarding
longer deferral); the combination approach (bundling current
land use change and forestry emissions reductions with
future reductions in the buyer's allowed amount); a
technology-acceleration approach; and an insurance approach.

PublicationDemand Growth versus Market Share Gains : Decomposing World Manufacturing Import Growth(World Bank, Washington, DC, 2013-02)This paper decomposes manufacturing import growth rates in a selected set of large industrial and developing countries (five industrial and eight developing) and measures the relative contributions of domestic demand and market share changes for two separate periods 1991/92 - 2001/02 and 2001/02 - 2007/08. It also shows the shares of imports both from the rest of the world and from developing countries for aggregate and three-digit manufacturing sectors. Import growth is much higher during the 2000s driven by higher demand growth rates. While market share changes explain most of the growth during the 1990s, its contribution is relatively smaller during the 2000s. Imports from developing countries have grown much faster both in industrial and developing country markets driven primarily by market share changes. However, more than half of market share gains by developing countries are caused by the exports of China, which accounts for more than 70 percent of market share gains of developing countries in the sample countries during the 2000s. Despite rapid growth, developing countries' share in the gross absorption of the sample countries is still low and can expand substantially even if demand growth is much lower in the near future.

PublicationGovernment Connections and Financial Constraints : Evidence from a Large Representative Sample of Chinese Firms(World Bank, Washington, DC, 2013-02)This paper examines the role of firms' government connections, defined by government intervention in the appointments of Chief Executive Officers and the status of state ownership, in determining the severity of financial constraints faced by Chinese firms. In line with the previous literature, the paper demonstrates that investment by non-state firms is highly sensitive to internal cash flows, while no such sensitivity is found for government-owned enterprises. Even within the subset of non-state firms, government connections are associated with substantially less severe financial constraints (less reliance on internal cash flows to fund investment). The paper also finds that large non-state firms with weak government connections are especially financially constrained, due perhaps to the formidable hold that their state rivals have on financial resources after the "grabbing-the-big-and-letting-go-the-small" privatization program in China. Firms with government-appointed Chief Executive Officers also have significantly lower investment intensities, due perhaps to their lower-powered incentives. The empirical results suggest that government connections play an important role in explaining Chinese firms' investment behavior and financing conditions, and provide further evidence on the nature of the misallocation of credit by China's dominant state-owned banks.

PublicationExternal Shocks, Fiscal Policy and Income Distribution : Alternative Scenarios for Moldova(World Bank, Washington, DC, 2013-02)The economy of Moldova, which has one of the lowest levels of gross national income per capita in the World Bank Europe and Central Asia region, is strongly linked to the outside world, especially to the neighboring countries of the European Union and the Commonwealth of Independent States. This paper analyzes a set of scenarios for Moldova up to 2020, defined to shed light on issues related to an alternative future dominated by goods and services exports as opposed to today's reliance on worker remittances. The analysis is based on a Moldovan version of MAMS (Maquette for Millennium Development Goal Simulations), a CGE (Computable General Equilibrium) model for country strategy analysis. In sum, the impact of increased export demand and productivity growth is more positive when these shocks are directed to manufacturing, a sector more heavily linked to international trade, compared with agriculture. Increased productivity in transport and communications generates faster growth with widely diffused benefits, reaching households in a relatively equitable manner compared with foreign trade-induced growth. A comparison between adverse shocks in two areas, higher energy import prices, and lower remittances, designed to have similar effects on gross domestic product, suggests that a remittance shock leads to less of a poverty increase, related to the fact that remittance-receiving households are not highly vulnerable; among sectors, agriculture is most vulnerable due to heavy energy reliance. Finally, well-targeted transfer schemes may offer an effective tool for diffusing the benefits of economic growth to the whole population, perhaps also contributing to more general acceptance of structural change.

PublicationWeight Calculations for Panel Surveys with Sub-sampling and Split-off Tracking(World Bank, Washington, DC, 2013-02)The Living Standards Measurement Study -- Integrated Surveys on Agriculture project collects agricultural and livelihood data in seven countries in Sub-Saharan Africa. In order to maintain representativeness as much as possible over multiple rounds of data collection, a sub-sample of households are selected to have members that have left the household tracked and interviewed in their new location with their new household members. Since the sub-sampling occurs at the level of the household but tracking occurs at the level of the individual, a number of issues arise with the correct calculation for the sub-sampling and attrition corrections. This paper is based on the panel weight calculations for the initial rounds of the Integrated Surveys on Agriculture surveys in Uganda and Tanzania, and describes the methodology used for calculating the weight components related to sub-sampling, tracking, and attrition, as well as the criteria used for trimming and post-stratification. It also addresses complications resulting from members previously classified as having attrited from the sample returning in later rounds.

PublicationPoverty, Inequality, and the Local Natural Resource Curse(World Bank, Washington, DC, 2013-02)The extent to which local communities benefit from commodity booms has been subject to wide but inconclusive investigations. This paper draws from a new district-level database to investigate the local impact on socioeconomic outcomes of mining activity in Peru, which grew almost twentyfold in the last two decades. The authors find evidence that producing districts have better average living standards than otherwise similar districts: larger household consumption, lower poverty rate, and higher literacy. However, the positive impacts from mining decrease significantly with administrative and geographic distance from the mine, while district-level consumption inequality increases in all districts belonging to a producing province. The inequalizing impact of mining activity, both across and within districts, may explain part of the current social discontent with mining activities in the country, even despite its enormous revenues.
