An observational study infers the effects caused by a treatment, policy, program, intervention, or exposure in a context in which randomized experimentation is unethical or impractical. One task in an observational study is to adjust for visible pretreatment differences between the treated and control groups. Multivariate matching and weighting are two modern forms of adjustment. This handbook provides a comprehensive survey of the most recent methods of adjustment by matching, weighting, machine learning and their combinations. Three additional chapters introduce the steps from association to causation that follow after adjustments are complete. When used alone, matching and weighting do not use outcome information, so they are part of the design of an observational study. When used in conjunction with models for the outcome, matching and weighting may enhance the robustness of model-based adjustments. The book is for researchers in medicine, economics, public health, psychology, epidemiology, public program evaluation, and statistics who examine evidence of the effects on human beings of treatments, policies or exposures.
Most of the world's people live in "developing" economies, as do most of the world's poor. The predominant means of economic development is economic growth. In this book Gary Fields asks to what extent and in what circumstances economic growth improves the material standard of living of a country's people. Most development economists agree that economic growth raises the incomes of people in all parts of the income distribution and lowers the poverty rate. At the same time, some groups lose out because of changes accompanying economic growth. Fields examines these beliefs, asking what variables should be measured to determine whether progress is being made and what policies and circumstances cause some countries to do better than others. He also shows how the same data can be interpreted to reach different, even conflicting, conclusions. Using both theoretical and empirical approaches, Fields defines and examines inequality, poverty, income mobility, and economic well-being. Finally, he considers various policies for broad-based growth. Copublished with the Russell Sage Foundation.
This is the first volume in an ambitious new series-"Patterns of Potential Human Progress"-inspired by the UN Millennium Development Goals (MGDs) and other initiatives to improve the global condition. The first and most fundamental of these goals-reducing poverty worldwide-is the focus of this book. Using the large-scale computer program called International Futures (IFs) developed over three decades at the prestigious University of Denver Graduate School of International Studies, this book explores the most extensive set of forecasts of global poverty ever made-providing a wide range of scenarios based on an authoritative array of data. It transcends the "$1 a day" baseline measure of pover...
A Brookings Institution Press and Carnegie Endowment for International Peace publication Many of the countries that have recently converted to a market-based economic system have also experienced an alarming increase in income inequality — a widening gap between the haves and have nots. But to what extent is the increase in inequality also increasing the opportunities for economic advancement — particularly for those at the bottom of the economic ladder? Does the creation of greater opportunities make a region's move to the market politically acceptable? And, if opportunities don't increase along with inequality, will it eventually cause a political backlash against a country's market po...
