Book excerpt: The idea of social capital allows scholars to assess the quality of relationships among people within a particular community and show how that quality affects the ability to achieve shared goals. With evidence collected from sixty-nine villages in India, Krishna investigates what social capital is, how it operates in practice, and what results it can be expected to produce. Does social capital provide a viable means for advancing economic development, promoting ethnic peace, and strengthening democratic governance? The world is richer than ever before, but more than a fifth of its people are poor and miserable. Civil wars and ethnic strife continue to mar prospects for peace. Democracy is in place in most countries, but large numbers of citizens do not benefit from it. How can development, peace and democracy become more fruitful for the ordinary citizen? This book shows how social capital is a crucial dimension of any solution to these problems.
