Throughout the book, Haberler's contributions demonstrate the clarity of his analyses for exploring the complex economics of policy issues and for identifying key governmental responses to problems of unemployment, trade, and development. Presenting Haberler as the eclectic economist he is, the editors show that far from being an ideologue, Haberler is an economist who uses whatever approaches and theories are appropriate for the problems he considers. The portrait that emerges is one of a multifaceted thinker, able to choose freely among competing theories and to effectively apply them to complex and demanding policy issues.
