Compared with other developed nations, the United States is unique in its high rates of both gun ownership and murder. Although widespread gun ownership does not have much effect on the overall crime rate, gun use does make criminal violence more lethal and has a unique capacity to terrorize the public. Gun crime accounts for most of the costs of gun violence in the United States, which are on the order of $100 billion per year. But that is not the whole story. Guns also provide recreational benefits and sometimes are used virtuously in fending off or forestalling criminal attacks. Given that guns may be used for both good and ill, the goal of gun policy in the United States has been to reduce the flow of guns to the highest-risk groups while preserving access for most people. There is no lack of opinions on policies to regulate gun commerce, possession, and use, and most policy proposals spark intense controversy. Whether the current system achieves the proper balance between preserving access and preventing misuse remains the subject of considerable debate. Evaluating Gun Policy provides guidance for a pragmatic approach to gun policy using good empirical research to help resolve conflicting assertions about the effects of guns, gun control, and law enforcement. The chapters in this volume do not conform neatly to the claims of any one political position. The book is divided into five parts. In the first section, contributors analyze the connections between rates of gun ownership and two outcomes of particular interest to society—suicide and burglary. Regulating ownership is the focus of the second section, where contributors investigate the consequences a large-scale combined gun ban and buy-back program in Australia, as well as the impact of state laws that prohibit gun ownership to those with histories of domestic violence. The third section focuses on efforts to restrict gun carrying and includes a critical examination of efforts in Pit

Water is becoming an increasingly scarce commodity in many parts of the world. Population growth plus a growing appetite for larger quantities of cheap water quality as a result of urban, industrial, and agricultural pollution coupled with increasing environmental demands have further reduced usable suppliers. This book brings together thirty of the best economic articles addressing water scarcity issues within the US and Mexico. By touching on a number of different issues, this volume clearly articulates the need for improving existing institutional arrangements as well as for developing new arrangements to address growing water scarcity problems.

Agricultural extension is critical for agricultural growth and food security, but making the extension system effective, demand driven, and responsive to the needs of a diverse set of producers remains a challenge. As part of the institutional reforms in the Democratic Republic of Congo (DRC), the extension system is being reviewed to identify strategies and practical actions to transform the system to better respond to the knowledge needs in a rapidly changing agriculture and food sector. This paper provides an in-depth review of the agricultural extension system of DRC including an analysis of its policies and legal framework, organization, and management; links to critical institutions; and capacity and incentive of different actors in the system. This review involved document analyses, interviews with key informants, and surveys of 107 extension organizations and 162 extension agents in 156 randomly selected villages in western DRC. This review suggests serious funding constraints, human resource management problems, no linkage and coordination within the extension system and with research and education systems, and a majority of underserved communities and farmers. This review also highlights a good opportunity given the huge human resources (more than 11,000 agents) deployed into the sectors and territories as part of the Ministry’s agricultural inspection system. However, their mandate is not clear and they currently focus on data collection (census) and checking what farmers do and limited in extension and advisory work. This review highlights the urgent need for human resource or civil service reform; public-sector commitment and funding; infrastructure rebuilding and skills upgrading in extension, education and training, and research organizations; and a unified policy or strategy with clear vision, mandate, targets, and performance-based incentive system.

COVID-19 has exacerbated concerns about the rise of the robots and other automation technologies. This paper analyzes empirically the impact of past major pandemics on robot adoption and inequality. First, we find that pandemic events accelerate robot adoption, especially when the health impact is severe and is associated with a significant economic downturn. Second, while robots may raise productivity, they could also increase inequality by displacing low-skilled workers. We find that following a pandemic, the increase in inequality over the medium term is larger for economies with higher robot density and where new robot adoption has increased more. Our results suggest that the concerns about the rise of the robots amid the COVID-19 pandemic seem justified.

The investment climate for firms producing genetically modified (GM) agricultural products has recently experienced considerable change, with the occurrence of remarkably high rate of farmer acceptance, but considerable consumer resistance. The present system that involves firms developing biotech products, farmers producing the products, food and related agribusiness industrial firms, and consumers of food, is very volatile. This however will soon be affected by changes in reulatory, trade and food safety regimes.This book addresses these key issues and is based on papers presented at the fourth meeting of The International Consortium on Agricultural Biotechnology Research (ICABR), on Economics of Agricultural Biotechnology, held at Ravello, Italy, in August 2000. Organized in four parts, this volume focuses on:Consumer reactions to GM food informationRegulatory issuesFarmer acceptance of biotech productsChanges in industrial organization in life science and food sectors
