"The distinctive feature of this book is that it provides a unified framework for the analysis of short- and medium-run macroeconomics. This gives students a model that they can use themselves to understand a wide range of real-world macroeconomic behaviour and policy issues. The authors introduce a new graphical model (IS/PC/MR) based on the 3-equation New Keynesian model used in modern macroeconomics. The three equations are BL the IS curve BL the Phillips curve and BL an interest rate-based monetary policy rule. The use of a common framework throughout for closed and open economies helps readers develop the economic intuition with which to address a diversity of macroeconomic problems. Applied chapters show how the models can be used to analyse performance in OECD economies over the past twenty-five years. The chapters on growth present an in-depth coverage of the Solow-Swan, endogenous and Schumpeterian models that allow the reader to understand how these approaches can be used to answer the big questions of growth: why some countries are rich and others, poor; why some catch up and others do not. Since the book is based on the mainstream 3-equation model used at the research frontier, the book gives students the economics background necessary for accessing advanced macroeconomics. It is also designed to appeal to graduate students, non-specialists in macroeconomics, professional economists and those from related disciplines who want a guide to the complexities of modern macroeconomics and to understand contemporary policy debates.

"China has a large national interest in the success of the international effort to hold human-induced increases in temperature to 1.5 degrees above pre-industrial levels—and therefore in global net emissions falling to net zero by 2050. China is essential to the success of the global effort—as a supplier of competitively priced equipment for the zero-emissions world economy and as the world's largest current source of greenhouse gas emissions. Success is more likely for China and the world with international specialization in line with global comparative advantage in goods production for the zero-emissions economy. This requires open international trade, with China supplying equipment to and drawing zero emissions semi-processed goods from abroad. Contemporary tendencies in international political economy make that difficult but not impossible."

"The fall of labor's share of GDP in the United States and many other countries in recent decades is well documented but its causes remain uncertain. Existing empirical assessments of trends in labor's share typically have relied on industry or macro data, obscuring heterogeneity among firms. In this paper, we analyze micro panel data from the U.S. Economic Census since 1982 and international sources and document empirical patterns to assess a new interpretation of the fall in the labor share based on the rise of \superstar firms." If globalization or technological changes advantage the most productive firms in each industry, product market concentration will rise as industries become increasingly dominated by superstar firms with high profits and a low share of labor in firm value-added and sales. As the importance of superstar firms increases, the aggregate labor share will tend to fall. Our hypothesis offers several testable predictions: industry sales will increasingly concentrate in a small number of firms; industries where concentration rises most will have the largest declines in the labor share; the fall in the labor share will be driven largely by between-firm reallocation rather than (primarily) a fall in the unweighted mean labor share within firms; the between-firm reallocation component of the fall in the labor share will be greatest in the sectors with the largest increases in market concentration; and finally, such patterns will be observed not only in U.S. firms, but also internationally. We find support for all of these predictions."
