Christopher H. Achen - Böcker

The Statistical Analysis of Quasi-Experiments by Christopher H. Achen is a foundational work for social scientists grappling with the realities of imperfect data. While randomized experiments remain the gold standard for causal inference, most research in political science, sociology, economics, and public policy relies on nonrandomized designs. Achen demonstrates that quasi-experiments—studies with nonrandom treatment groups or censored samples—pose unique statistical challenges that traditional regression or matching techniques cannot fully solve. Through careful critique and innovative solutions, he shows how common assumptions of control variables and model specification often fail, leaving policy evaluations and empirical findings biased or misleading.The book develops practical alternatives. Achen introduces methods ranging from two-stage least squares to advanced single-equation instrumental variable estimators, extending them to contexts with heteroskedasticity, nonlinearities, and censored samples. Drawing on case studies such as school desegregation, college admissions, and pretrial release systems, he illustrates both the pitfalls of conventional analysis and the power of more appropriate estimators. Written with applied researchers in mind, **The Statistical Analysis of Quasi-Experiments** balances theoretical rigor with accessibility, offering tools that can be computed with widely available software. More than a technical manual, it is a call for greater care and intellectual honesty in social science, highlighting how better statistical practice can produce more reliable insights into pressing issues of law, policy, and society.This title is part of UC Press's Voices Revived program, which commemorates University of California Press’s mission to seek out and cultivate the brightest minds and give them voice, reach, and impact. Drawing on a backlist dating to 1893, Voices Revived makes high-quality, peer-reviewed scholarship accessible once again using print-on-demand technology. This title was originally published in 1986.

European legislation affects countless aspects of daily life in modern Europe but just how does the European Union make such significant legislative decisions? How important are the formal decision-making procedures in defining decision outcomes and how important is the bargaining that takes place among the actors involved? Using a combination of detailed evidence and theoretical rigour, this volume addresses these questions and others that are central to understanding how the EU works in practice. It focuses on the practice of day-to-day decision-making in Brussels and the interactions that take place among the Member States in the Council and among the Commission, the Council and the European Parliament. A unique data set of actual Commission proposals are examined against which the authors develop, apply and test a range of explanatory models of decision-making, exemplifying how to study decision-making in other political systems using advanced theoretical tools and appropriate research design.

Democracy for Realists assails the romantic folk-theory at the heart of contemporary thinking about democratic politics and government, and offers a provocative alternative view grounded in the actual human nature of democratic citizens. Christopher Achen and Larry Bartels deploy a wealth of social-scientific evidence, including ingenious original analyses of topics ranging from abortion politics and budget deficits to the Great Depression and shark attacks, to show that the familiar ideal of thoughtful citizens steering the ship of state from the voting booth is fundamentally misguided. They demonstrate that voters--even those who are well informed and politically engaged--mostly choose parties and candidates on the basis of social identities and partisan loyalties, not political issues. They also show that voters adjust their policy views and even their perceptions of basic matters of fact to match those loyalties. When parties are roughly evenly matched, elections often turn on irrelevant or misleading considerations such as economic spurts or downturns beyond the incumbents' control; the outcomes are essentially random.Thus, voters do not control the course of public policy, even indirectly. Achen and Bartels argue that democratic theory needs to be founded on identity groups and political parties, not on the preferences of individual voters. Democracy for Realists provides a powerful challenge to conventional thinking, pointing the way toward a fundamentally different understanding of the realities and potential of democratic government.
