"This impressive study, based on a random sample of forty thousand Civil War soldiers both black and white, reaches important conclusions about their motivation and behavior. Its most significant findings emphasize the role of close social networks within companies and regiments in promoting combat performance, preventing desertion, and increasing survival rates in POW camps. Readable and accessible to nonspecialists, this book should find a wide audience among those interested in the Civil War as well as group behavior more generally."--James McPherson, author of the Pulitzer Prize-winning "Battle Cry of Freedom"

"This remarkable book is destined to become a classic in social science. It addresses issues of supreme importance and timeliness--loyalty, betrayal, heroism, cowardice, survival, the challenges of diversity, and the benefits of social bonds. It rests on rigorous statistical analysis of an extraordinary historical archive, and yet it is so readable as to be unputdownable. It deals with a single epochal event in one nation's history--the U.S. Civil War--and yet its lessons are highly relevant in many other eras and societies, including our own."--Robert Putnam, author of "Bowling Alone: The Collapse and Revival of American Community"

"Dora Costa and Matthew Kahn built a social science laboratory from the enlistment and pension records of men who fought in the Union Army during the American Civil War. In that remarkable laboratory they have discovered how friendship, community ties, and social status alter our choices. Read "Heroes and Cowards" for its reliable science; savor it for how it honors the harrowing circumstances that made the science possible."--Michael Hout, coauthor of "Century of Difference: How America Changed in the Last One Hundred Years"

"Dora Costa and Matthew Kahn have written a superb book on bravery in the Civil War. Their work informs us not only about courage under fire, but about the many settings where people are called upon to act for a common good. This is a pioneering piece of social science."--Edward L. Glaeser, Harvard University

"In the remarkable "Heroes and Cowards," Costa and Kahn demonstrate how social bonds helped determine which soldiers would fight to the death and which would flee for their lives, which soldiers would survive the deadly prison camps and which would succumb. The authors utilize the tools of social science to serve, rather than obscure, the riveting accounts by Union soldiers--the heroes, the cowards, and those in between."--Claude S. Fischer, University of California, Berkeley

"With its excellent blending of qualitative and quantitative data, this is a significant contribution to Civil War history and, more generally, to military history. It will be of great interest to economists, historians and general readers, especially the large number still fascinated by the Civil War."--Stanley L. Engerman, coauthor of "Time on the Cross"

"Dora Costa and Matthew Kahn are two accomplished scholars whose work offers substantially new insights, on why men desert and how this affects them; on the experience of black soldiers during and after the war; and on the migration patterns of war veterans. The research behind this book is based on data that has not previously been used by scholars, and their use of that data is imaginative and revealing. "Heroes and Cowards" is a significant contribution to ourknowledge of how Civil War veterans coped with the stresses of war and their lives after 1865."--Roger Ransom, author of "The Confederate States of America: What Might Have Been"

""Heroes and Cowards" is a remarkable and impressive piece of economic history, a unique book that will interest a large readership."--Louis P. Cain, Loyola University Chicago

The Evolution of Retirement is the first comprehensive economic history of retirement in America. With life expectancies steadily increasing, the retirement rate of men over age 64 has risen drastically. Dora L. Costa looks at factors underlying this increase and shows the dramatic implications of her findings for both the general public and the U.S. government.

Costa argues that the rise of retirement is the result of a culmination of historical trends initiated more than a century ago, not the consequence of abrupt social or institutional change. She attributes much of the long-term increase in retirement rates to steadily rising income, but argues that increased income is not the sole explanation. Over the course of this century, men's retirement decision has become less sensitive to increases or decreases in income, perhaps because retirement has become a time of discovery and personal fulfillment, rather than a time of withdrawal from activities and dependence on family.

Using statistical and demographic concepts, Costa explains trends in retirement data. Her examination sheds light on such important topics as rising incomes and retirement, work and disease, the job prospects of older workers, living arrangements of the elderly, the development of a retirement lifestyle, and pensions, and politics. She concludes with a look into the future and further evolution of retirement, addressing perhaps the most vexing problem of retirement policy, the impact of the aging Baby Boom generation on the Social Security System.

"[Costa's] major contribution is to show that, even without Social Security and Medicare, retirement would have expanded dramatically."--Robert J. Samuelson, "New Republic"
"An important book on a topic which has become popular with historians and is of major significance to politicians and economists."--Margaret Walsh, "Business History"

The twentieth century saw significant increases in both life expectancy and retirement rates-changes that have had dramatic impacts on nearly every aspect of society and the economy. Forecasting future trends in health and retirement rates, as we must do now, requires investigation of such long-term trends and their causes.
To that end, this book draws on new data-an extensive longitudinal survey of Union Army veterans born between 1820 and 1850-to examine the factors that affected health and labor force participation in nineteenth-century America. Contributors consider the impacts of a variety of conditions-including social class, wealth, occupation, family, and community-on the morbidity and mortality of the group. The papers investigate and address a number of special topics, including the influence of previous exposure to infectious disease, migration, and community factors such as lead in water mains. They also analyze the roles of income, health, and social class in retirement decisions, paying particular attention to the social context of disability.
Economists and historians who specialize in demography or labor, as well as those who study public health, will welcome the unique contributions offered by this book, which offers a clearer view than ever before of the workings and complexities of life, death, and labor during the nineteenth century.

The conditions for sustainable growth and development are among the most debated topics in economics, and the consensus is that institutions matter greatly in explaining why some economies are more successful than others over time. Probing the long-term effects of early colonial differences on immigration policy, land distribution, and financial development in a variety of settings, "Understanding Long-Run Economic Growth" explores the relationship between economic conditions, growth, and inequality, with a focus on how the monopolization of resources by the political elite limits incentives for ordinary people to invest in human capital or technological discovery. Among the topics discussed are the development of credit markets in France, the evolution of transportation companies in the United Kingdom and the United States, and the organization of innovation in the United States.
