Hayek Book Prize FinalistAn Economist Best Book of the YearA Foreign Affairs Best Book of the YearA Financial Times Summer Reading Favorite“Sweeping, authoritative and—for the times—strikingly upbeat…The overall argument is compelling and…it carries a trace of Schumpeterian subversion.”—The Economist“[An] important book…Lucid, empirically grounded, wide-ranging, and well-argued.”—Martin Wolf, Financial Times“Offers…much needed insight into the sources of economic growth and the kinds of policies that will promote it…All in Washington would do well to read this volume carefully.”—Milton Ezrati, ForbesInequality is on the rise, growth stagnant, the environment in crisis. Covid seems to have exposed every crack in the system. We hear calls for radical change, but the answer is not to junk our economic system but to create a better form of capitalism.An ambitious reappraisal of the foundations of economic success that shows a fair and prosperous future is ours to make, The Power of Creative Destruction draws on cutting-edge theory and hard evidence to examine today’s most fundamental economic questions: what powers growth, competition, globalization, and middle-income traps; the roots of inequality and climate change; the impact of technology; and how to recover from economic shocks. We owe our modern standard of living to innovations enabled by free-market capitalism, it argues, but we also need state intervention—with checks and balances—to foster economic creativity, manage social disruption, and ensure that yesterday’s superstar innovators don’t pull the ladder up after them.

It has long been recognized that productivity growth and the business cycle are closely interrelated. Yet, until recently, the two phenomena have been investigated separately in the economics literature. This book provides the first consistent attempt to analyze the effects of macroeconomic volatility on productivity growth, and also the reverse causality from growth to business cycles. The authors show that by looking at the economy through the lens of private entrepreneurs, who invest under credit constraints, one can go some way towards explaining persistent macroeconomic volatility and the effects of volatility on growth. Beginning with an analysis of the effects of volatility on growth, the authors argue that the lower the level of financial development in a country the more detrimental the effect of volatility on growth. This prediction is confirmed by cross-country panel regressions. The data also suggests that a fixed exchange rate regime or more countercyclical budgetary policies are growth-enhancing in countries with a lower level of financial development. The former reduce aggregate volatility whereas the latter reduce the negative effects of volatility on long-term productivity-enhancing investment by firms. The book concludes with an investigation into how the interplay between credit constraints and pecuniary externalities is sufficient to generate persistent business cycles and to explain the occurrence of currency crises.

Over the past decade European economic integration has seen considerable institutional success, but the economic performance of the EU has been varied. While macroeconomic stability has improved and an emphasis on cohesion preserved, the EU economic system has not delivered satisfactory growth performance.This book is the report of a high-level group commissioned by the President of the European Commission to review the EU economic system and propose a blueprint for an economic system capable of delivering faster growth along with stability and cohesion. It assesses the EU s economic performance, examines the challenges facing the EU in the coming years, and presents a series of recommendations.The report views Europe's unsatisfactory growth performance during the last decades as a symptom of its failure to transform into an innovation-based economy. It has now become clear that the context in which economic policies have been developed has changed fundamentally over the past thirty years. A system built around the assimilation of existing technologies, mass production generating economics of scale, and an industrial structure dominated by large firms with stable markets and long term employment patterns no longer delivers in the world of today, characterized by economic globalization and strong external competition. What is needed now is more opportunity for new entrants, greater mobility of employees within and across firms, more retraining, greater reliance on market financing, and higher investment in both R&D and higher education. This requires a massive and urgent change in economic policies in Europe.

The 1986 article by Grossman and Hart "A Theory of Vertical and Lateral Integration " has provided a framework for understanding how firm boundaries are defined and how they affect economic performance. The property rights approach has provided a formal way to introduce incomplete contracting ideas into economic modeling. The Impact of Incomplete Contracts on Economics collects papers and opinion pieces on the impact that this property right approach to the firm has had on the economics profession. It shows that the impact has been felt sometimes in significant ways in a variety of fields, ranging from the theory of the firm and their internal organization to industrial organization, international trade, finance, management, public economy, and political economy and political science. Beyond acknowledging how the property rights approach has permeated economics as a whole, the contributions in the book also highlight the road ahead---how the paradigm may change the way research is performed in some of the fields, and what type of research is still missing. The book concludes with a discussion of the foundations of the property rights, and more generally the incomplete contracting, approaches and with a series of contributions showing how behavioral considerations may provide a new way forward.

The Handbook of Economic Growth, edited by Philippe Aghion and Steven Durlauf, with an introduction by Robert Solow, features in-depth, authoritative survey articles by the leading economists working on growth theory.

Volume 1a, the first in this two volume set, covers theories of economic growth, the empirics of economic growth, and growth policies and mechanisms.

Volume 1b, the second in this two volume set, covers technology, trade and geography, and growth and socio-economic development.

The Handbook of Economic Growth provides a broad review of the research topics, empirical findings, and methods that comprise modern growth economics. The chapters, written by research leaders, summarize and evaluate recent advances while explaining where further research might be profitable. With analyses that are provocative and controversial because they are so directly relevant to public policy and private decision-making, this volume upholds the standard for excellence in applied economics set by Volumes 1A and 1B (2005).

Offers definitive theoretical and empirical scholarship about growth economics Presents as a guiding principle the search for a theoretical framework consistent with the theories and data that describe growth economics Familiarizes readers with common empirical methods and empirical results

The study of economic growth has been an integral part of economics since its inception as a scholarly discipline. Research about the sources and implications of economic growth remain strong, and growth economics regularly takes advantage of advances in new tools and techniques. Volume Two of the Handbook of Economic Growth summarizes recent advances in theoretical and empirical work while offering new perspectives on a range of growth mechanisms, from the roles played by institutions and organizations to the ways factors beyond capital accumulation and technological change can affect growth.

Empowers readers to evaluate the work of other economists and to plan their own research projects Illuminates the implications of empirical methods and results Demonstrates the value of empirical testing, with its implicit conclusion that our understanding of economic growth will help everyone make better decisions

The question of how inequality is generated and how it reproduces over time has been a major concern for social scientists for more than a century. Yet the relationship between inequality and the process of economic development is far from being well understood. These Raffaele Mattioli Lectures have brought together two of the world's leading economists, Professors Philippe Aghion (a theorist) and Jeffrey Williamson (an economic historian), to question the conventional wisdom on inequality and growth, and address its inability to explain recent economic experience. Professor Aghion assesses the affects of inequality on growth, and asks whether inequality matters: if so why is excessive inequality bad for growth, and is it possible to reconcile aggregate findings with macroeconomic theories of incentives? In the second part Jeffrey Williamson discusses the Kuznets hypothesis, and focuses on the causes of the rise of wage and income inequality in developed economies.

Macroeconomics would not be what it is today without Edmund Phelps. This book assembles the field's leading figures to highlight the continuing influence of his ideas from the past four decades. Addressing the most important current debates in macroeconomic theory, it focuses on the rates at which new technologies arise and information about markets is dispersed, information imperfections, and the heterogeneity of beliefs as determinants of an economy's performance. The contributions, which represent a breadth of contemporary theoretical approaches, cover topics including the real effects of monetary disturbances, difficulties in expectations formation, structural factors in unemployment, and sources of technical progress. Based on an October 2001 conference honoring Phelps, this incomparable volume provides the most comprehensive and authoritative account in years of the present state of macroeconomics while also pointing to its future.
