This paper investigates the presence of endogenous peer effects in the adoption of formal property rights. Using data from a unique land titling experiment held in an unplanned settlement in Dar es Salaam, the analysis finds a strong, positive impact of neighbor adoption on the household's choice to purchase a land title. The paper also shows that this relationship holds in a separate, identical experiment held a year later in a nearby community, as well as in administrative data for more than 160,000 land parcels in the same city.

The paper focuses its analysis on the last three decades of the twentieth century. The basic assumption is that Egypt's economic performance during this period was less than satisfactory compared with the most successful examples in the far East and elsewhere. The paper also assumes that Egypt's initial conditions at midcentury compared favorably with the winners in the development race at the end of the century. Egypt has achieved positive progress, no doubt, yet compared with the higher performers in Asia, and given its favorable good initial conditions, the record seems quite mediocre.

South Africa's growth experience provides an example of how contrasting growth trends long-term decline followed by improved growth pivot around political change, in this case a transition to democracy. In the decade prior to 1994, South Africa experienced the worst period of economic growth since the end of the Second World War, with growth variable and declining.

The real exchange rate was not at the center of the first generation of neoclassical growth models, nor was it prominent among the policy prescriptions that flowed from those models. Recent analyses, in contrast, have paid it more attention. This paper analyzes the role of the real exchange rate in the growth process, the channels through which the real exchange rate influences other variables, and policies useful (and not useful) for governing the real rate. An appendix provides econometric evidence supportive of the emphases in the text.

There is no longer any serious debate about whether greenhouse gas emissions from human activity are altering the earth's climate. There is also a broad consensus that efficient mitigation of emissions will require carbon pricing via market based instruments (charges or auctioned tradable permits). The remaining controversies stem mostly from economic and technological forecasting uncertainties, disputes about global and intergenerational equity, and political divisions over collective measures to combat climate change.

Nonperforming Loans (NPLs) in the banking system constituted 16.5 percent of total loans, owing primarily to the corporate sector. The Credit Bureau, maintained by the Association of Serbian Banks, also discloses dramatic increases in corporate and retail defaults over the past year. NPL resolution and loan loss mitigation is hampered by a still evolving but uneven collateral and enforcement framework that complicates restructuring and leads to delays and lower recoveries in execution procedures.

The operations policy on Development Policy Lending (DPL), approved by the Board in August 2004, requires that the Bank systematically analyze whether specific country policies supported by an operation are likely to have "significant effects" on the country's environment, forests, and other natural resources. The implicit objective behind this requirement is to ensure that there is adequate capacity in the country to deal with adverse effects on the environment, forests, and other natural resources that the policies could trigger, even at the program design stage.

Climate change presents a profound challenge to food security and development. Negative impacts from climate change are likely to be greatest in regions that are currently food insecure and may even be significant in those regions that have made large gains in reducing food insecurity over the past half-century. Adaptation in the agricultural sector is being given a high priority within this effort because of the inherent sensitivity of food production to climate and the strong inter-linkages that exist between climate, agriculture, and economic growth and development.

This paper tracks the process through which FIAS, the investment climate advisory service of the World Bank Group advised the government of Latvia from 1998 to 2004 on ways to improve the business environment, achieve higher rates of economic growth, and thereby alleviate poverty. This case study shows that it is reasonable to describe how assistance by FIAS led to an improved business environment.

The Country Environmental Analysis (CEA) for Timor-Leste identifies environmental priorities through a systematic review of environmental issues in natural resources management and environmental health in the context of the country's economic development and environmental institutions. Lack of data has been the main limitation in presenting a more rigorous analysis. Nevertheless, the report builds on the best available secondary data, presents new data on the country's wealth composition, and derives new results on the costs of water and air pollution.

This paper explores how a 'conflict and violence sensitive' framework in project assessment, design and implementation facilitates early identification and mitigation of negative consequences of competition and dispute, and promotes sustainable development over the longer term. It discusses the role of renewable resources in perpetuating conflict and violence, and distills lessons from selected development programming experiences in managing conflict risks associated with these dynamics.

Capitalizing on the most recent estimates of agricultural price distortions in China and in other countries, this paper assesses the economic and poverty impact of global and domestic trade reform in China. It also examines the interplay between the trade reforms and factor market reforms aimed at improving the allocation of labor within the Chinese economy. The results suggest that trade reforms in the rest of the world, land reform and hukou reform all serve to reduce poverty, while unilateral trade reforms result in a small poverty increase.
