32. Why Maintaining Tropical Forests Is Essential and Urgent for a Stable Climate

- Abstract:
- Tropical forests have the highest carbon density and cover more land area than forests in any other biome. They also serve a vital role as a natural buffer to climate change ―capturing 2.2–2.7 Gt of carbon per year. Unfortunately, tropical forests, mangroves, and peatlands are also subjected to the highest levels of deforestation and account for nearly all net emissions from Forestry and Other Land Use (FOLU) (1.1–1.4 Gt C / year). Net emissions from FOLU accounted for only 11% of total anthropogenic greenhouse gas emissions or 14% of total carbon emissions in 2010, though these figures are somewhat misleading and do not reflect the full potential of tropical forests to mitigate climate change. First, net FOLU emissions have reduced only slightly while emissions from all other sectors have skyrocketed. Secondly, the FOLU net flux is made up of two larger fluxes —deforestation emissions (2.6–2.8 Gt C / year) minus sequestration from forest regrowth (1.2–1.7 Gt C / year). Additionally, intact tropical forests also appear to be capturing at least 1.0 Gt C/ year. Gross deforestation, therefore, accounts for over a quarter of all carbon emissions, and tropical forests have removed 22–26% of all anthropogenic carbon emissions in the 2000s. If deforestation were halted entirely, forests were allowed to regrow, and mature forests were left undisturbed, tropical forests alone could have captured 25–35% of all other anthropogenic carbon emissions. On the other hand, if climate change continues unabated, forests could turn from net sinks to net sources of carbon. Forestrelated activities are among the most economically feasible and cost-effective mitigation strategies, which are important for both short- and long-term mitigation strategies. Action is needed immediately to utilize these natural mitigation solutions, and we need coordinated and comprehensive forest-related policies for mitigation. An international mechanism such as REDD+ is essential to realize the great natural potential for tropical forests to stabilize the climate.

33. To Charge or Not to Charge: Evidence from a Health Products Experiment in Uganda
- Author:
- Dean Karlan, Pia Raffler, Greg Fischer, and Margaret McConnell
- Publication Date:
- 11-2014
- Content Type:
- Working Paper
- Institution:
- Center for Global Development
- Abstract:
- In a field experiment in Uganda, we find that demand after a free distribution of three health products is lower than after a sale distribution. This contrasts with work on insecticide-treated bed nets, highlighting the importance of product characteristics in determining pricing policy. We put forward a model to illustrate the potential tension between two important factors, learning and anchoring, and then test this model with three products selected specifically for their variation in the scope for learning. We find the rank order of shifts in demand matches with the theoretical prediction, although the differences are not statistically significant.

34. The Political Economy of Bad Data: Evidence from African Survey Administrative Statistics
- Author:
- Amanda Glassman and Justin Sandefur
- Publication Date:
- 07-2014
- Content Type:
- Working Paper
- Institution:
- Center for Global Development
- Abstract:
- Across multiple African countries, discrepancies between administrative data and independent household surveys suggest official statistics systematically exaggerate development progress. We provide evidence for two distinct explanations of these discrepancies. First, governments misreport to foreign donors, as in the case of a results-based aid program rewarding reported vaccination rates. Second, national governments are themselves misled by frontline service providers, as in the case of primary education, where official enrollment numbers diverged from survey estimates after funding shifted from user fees to per pupil government grants. Both syndromes highlight the need for incentive compatibility between data systems and funding rules.

35. Delivering on a Data Revolution in Sub-Saharan Africa
- Author:
- Amanda Glassman and Alex Ezeh
- Publication Date:
- 07-2014
- Content Type:
- Policy Brief
- Institution:
- Center for Global Development
- Abstract:
- Despite improvements in censuses and household surveys, the building blocks of national statistical systems in sub-Saharan Africa remain weak. Measurement of fundamentals such as births and deaths, growth and poverty, taxes and trade, land and the environment, and sickness, schooling, and safety is shaky at best. The challenges are fourfold: (1) national statistics offices have limited independence and unstable budgets, (2) misaligned incentives encourage the production of inaccurate data, (3) donor priorities dominate national priorities, and (4) access to and usability of data are limited. The Data for African Development Working Group's recommendations for reaping the benefits of a data revolution in Africa fall into three categories: (1) fund more and fund differently, (2) build institutions that can produce accurate, unbiased data, and (3) prioritize the core attributes of data building blocks.

36. Self-Selection into Credit Markets: Evidence from Agriculture in Mali

- Content Type:
- Working Paper
- Institution:
- Center for Global Development
- Abstract:
- We partnered with a micro-lender in Mali to randomize credit offers at the village level. Then, in no-loan control villages, we gave cash grants to randomly selected households. These grants led to higher agricultural investments and profits, thus showing that liquidity constraints bind with respect to agricultural investment. In loan-villages, we gave grants to a random subset of farmers who (endogenously) did not borrow. These farmers have lower – in fact zero – marginal returns to the grants. Thus we find important heterogeneity in returns to investment and strong evidence that farmers with higher marginal returns to investment self-select into lending programs.

37. Stunted Growth: Why Don't African Firms Create More Jobs?
- Author:
- Vijaya Ramachandran, Leonardo Iacovone, and Martin Schmidt
- Publication Date:
- 02-2014
- Content Type:
- Working Paper
- Institution:
- Center for Global Development
- Abstract:
- Many countries in Africa suffer high rates of underemployment or low rates of productive employment; many also anticipate large numbers of people to enter the workforce in the near future. This paper asks the question: Are African firms creating fewer jobs than those located elsewhere? And, if so, why? One reason may be that weak business environments slow the growth of firms and distort the allocation of resources away from better-performing firms, hence reducing their potential for job creation.

38. Development as Diffusion: Manufacturing Productivity and Sub-Saharan Africa's Missing Middle
- Author:
- Vijaya Ramachandran, Alan Gelb, and Christian J. Meyer
- Publication Date:

- Content Type:
- Working Paper
- Institution:
- Center for Global Development
- Abstract:
- We consider economic development of Sub-Saharan Africa from the perspective of slow convergence of productivity, both across sectors and across firms within sectors. Why have "productivity enclaves", islands of high productivity in a sea of smaller low-productivity firms, not diffused more rapidly? We summarize and analyze three sets of factors: First, the poor business climate, which constrains the allocation of production factors between sectors and firms. Second, the complex political economy of business-government relations in Africa's small economies. Third, the distribution of firm capabilities. The roots of these factors lie in Africa's geography and its distinctive history, including the legacy of its colonial period on state formation and market structure.
