Subsistence production: a sign of market failure. Commercialization cannot be left to the market. Household effects of commercialization. Nutrition effects of commercialization. Policy action needed.

Global temperatures have increased at an unprecedented pace in the past 40 years. This paper finds that increases in temperature have uneven macroeconomic effects, with adverse consequences concentrated in countries with hot climates, such as most low-income countries. In these countries, a rise in temperature lowers per capita output, in both the short and medium term, through a wide array of channels: reduced agricultural output, suppressed productivity of workers exposed to heat, slower investment, and poorer health. In an unmitigated climate change scenario, and under very conservative assumptions, model simulations suggest the projected rise in temperature would imply a loss of around 9 percent of output for a representative low-income country by 2100.

This book presents the basic model of an agricultural household that underlies most of the case studies undertaken so far. The model assumes that households are price-takers and is therefore recursive. The decisions modeled include those affecting production and the demand for inputs and those affecting consumption and the supply of labor. Comparative results on selected elasticities are presented for a number of economies. The empirical significance of the approach is demonstrated in a comparison of models that treat production and consumption decisions separately and those in which the decisionmaking process is recursive. The book summarizes the implications of agricultural pricing policy for the welfare of farm households, marketed surplus, the demand for nonagricultural goods and services, the rural labor market, budget revenues, and foreign exchange earnings. In addition, it is shown that the basic model can be extended in order to explore the effects of government policy on crop composition, nutritional status, health, saving, and investment and to provide a more comprehensive analysis of the effects on budget revenues and foreign exchange earnings. Methodological topics, primarily the data requirements of the basic model and its extensions, along with aggregation, market interaction, uncertainty, and market imperfections are discussed. The most important methodological issues - the question of the recursive property of these models - is also discussed.

A distinguished Yale economist and legal scholar’s argument that law, of all things, has the potential to rescue us from the next economic crisis. After the economic crisis of 2008, private-sector spending took nearly a decade to recover. Yair Listokin thinks we can respond more quickly to the next meltdown by reviving and refashioning a policy approach whose proven success is too rarely acknowledged. Harking back to New Deal regulatory agencies, Listokin proposes that we take seriously law’s ability to function as a macroeconomic tool, capable of stimulating demand when needed and relieving demand when it threatens to overheat economies. Listokin makes his case by looking at both positive and cautionary examples, going back to the New Deal and including the Keystone Pipeline, the constitutionally fraught bond-buying program unveiled by the European Central Bank at the nadir of the Eurozone crisis, the ongoing Greek crisis, and the experience of U.S. price controls in the 1970s. History has taught us that law is an unwieldy instrument of macroeconomic policy, but Listokin argues that under certain conditions it offers a vital alternative to the monetary and fiscal policy tools that stretch the legitimacy of technocratic central banks near their breaking point while leaving the rest of us waiting and wallowing.

Discusses ways in which the role of the state in promoting agricultural growth and development may be redefined. This report presents the proceedings of the 14th World Bank Agricultural Symposium held in January 1994. The papers explore ways in which the role of the state in promoting agricultural growth and development may be redefined. They also capitalize on important lessons emerging from experiences around the world. The report suggests that changing the role of government from market domination towards the provision of a regulatory framework that facilitates private sector activity is an ongoing process rather than a one-time occurrence. The papers also illustrate the wide variety of issues and the different approaches in the various countries that are redefining the role of government in agricultural development.

This book is an outcome of the conference on the linkages between macroeconomics and agricultural trade in 1986. It establishes some of the fundamental influences on the exchange rate. The book develops linkages between the macroeconomy and agriculture using traditional models.

The social cost of carbon (SC-CO2) is an economic metric intended to provide a comprehensive estimate of the net damages - that is, the monetized value of the net impacts, both negative and positive - from the global climate change that results from a small (1-metric ton) increase in carbon-dioxide (CO2) emissions. Under Executive Orders regarding regulatory impact analysis and as required by a court ruling, the U.S. government has since 2008 used estimates of the SC-CO2 in federal rulemakings to value the costs and benefits associated with changes in CO2 emissions. In 2010, the Interagency Working Group on the Social Cost of Greenhouse Gases (IWG) developed a methodology for estimating the SC-CO2 across a range of assumptions about future socioeconomic and physical earth systems. Valuing Climate Changes examines potential approaches, along with their relative merits and challenges, for a comprehensive update to the current methodology. This publication also recommends near- and longer-term research priorities to ensure that the SC- CO2 estimates reflect the best available science.

This study examines the broad range of factors driving farm management decisions that can improve the environment, including drawing on the experiences of OECD countries.
