This paper distinguishes two kinds of Endogenous Business Cycle models; EBC1 models, which display dynamic indeterminacy, and EBC2 models, which display steady-state indeterminacy. Both strands of the literature have their origins in the sunspot literature that developed at the University of Pennsylvania in the 1980s. I argue that EBC1 models are part of the evolution of modern macroeconomics that has classical roots dating back to the 1920s. EBC2 models provide a microfoundation to one of the most important ideas to emerge from Keynes' (1936) General Theory; that high involuntary unemployment can persist as part of the steady-state equilibrium of a market economy.

Traditionally, economic growth and business cycles have been treated independently. However, the dependence of GDP levels on its history of shocks, what economists refer to as “hysteresis,” argues for unifying the analysis of growth and cycles. In this paper, we review the recent empirical and theoretical literature that motivate this paradigm shift. The renewed interest in hysteresis has been sparked by the persistence of the Global Financial Crisis and fears of a slow recovery from the Covid-19 crisis. The findings of the recent literature have far-reaching conceptual and policy implications. In recessions, monetary and fiscal policies need to be more active to avoid the permanent scars of a downturn. And in good times, running a high-pressure economy could have permanent positive effects.

This volume presents the most complete collection available of the work of Victor Zarnowitz, a leader in the study of business cycles, growth, inflation, and forecasting.. With characteristic insight, Zarnowitz examines theories of the business cycle, including Keynesian and monetary theories and more recent rational expectation and real business cycle theories. He also measures trends and cycles in economic activity; evaluates the performance of leading indicators and their composite measures; surveys forecasting tools and performance of business and academic economists; discusses historical changes in the nature and sources of business cycles; and analyzes how successfully forecasting firms and economists predict such key economic variables as interest rates and inflation.

Business Cycles in Economic Thought underlines how, over the time span of two centuries, economic thought interacted with cycles in a continuous renewal of theories and rethinking of policies, whilst economic actions embedded themselves into past economic thought. This book argues that studying crises and periods of growth in different European countries will help to understand how different national, political and cultural traditions influenced the complex interaction of economic cycles and economic theorizing. The editors of this great volume bring together expert contributors consisting of economists, historians of economic thought and historians of economics, to analyse crises and theories of the nineteenth and the twentieth century. This is alongside a comprehensive outlook on the most relevant advances of economic theory in France, Germany and Italy, as well as coverage of non-European countries, such as the United States. Several of the highly prestigious Villa Vigoni Trilateral Conferences formed the background for the discussions in this book. This volume is of great interest to students and academics who study history of economic thought, political economy and macroeconomics.

This book investigates the South African business cycle and its links to structural change in the economy. Against the backdrop of the democratic transition in 1994 and the global financial crisis, the authors study how business cycles in South Africa have changed and how cycles are related to key developments in the financial markets, international trade and business sentiment in the country. By focusing on peaks and troughs in economic activity – so-called ‘turning-point cycles’ – the book links up with the common approach of international policymakers to studying fluctuations in economic activity. The authors also introduce new approaches to measuring phases of the business cycle (to understand slow recoveries after the global crisis), provide comprehensive descriptions to complement quantitative analyses, and utilize new data sources that allow the measurement of economic activity over longer periods. As such, the book provides the first integrated overview of business cycles in an emerging market, providing academics and policymakers with a better understanding of the measurement challenges and drivers of the cycle.

This is a key year for the evolution of international markets. The global economy is experiencing the most severe downturn since the thirties, it is temporarily leaving a path of sustained growth that characterized the last decades, and is facing an impressive decline of trade between countries. Banks are going bankrupt, the stock market has crashed, rms are going out of bu- ness or drastically reducing their production and exports, workers are being red and investment in new business creation or innovation is shrinking. Meanwhile, consumers con dence has dropped at its minimum, aggregate demand has been declining for months and expansionary policies and int- national coordination have failed to counteract the crisis until now. It is quite likely that all this will change sooner or later, but at the end of this crisis our understanding of the macroeconomy may change as well. In front of these crucial events, this book is not an attempt at proposing a radically new way of interpreting macroeconomic phenomena, and, as a m- ter of fact, it is not even a book on macroeconomic theory. My more modest goal is to collect a number of insights derived from recent research on the role of competition and innovation in the analysis of three topics: business cycles, trade and growth through innovations.
