Combining powerful insights from theory with close observation of data, Robert Barro’s new book goes a long way toward the establishment of an empirically based macroeconomic theory.

Barro first presents a positive theory of government economic policymaking by using applied game theory to model strategic interactions between policymakers and the private sector. He applies this framework to questions of rules, discretion, and reputation in monetary policy. He then takes a close look at whether monetary disturbances have a strong effect on business fluctuations, concluding that the effect is neither as strong nor as pervasive as many economists have believed. He consequently turns his attention from monetary policy to fiscal policy. The originator of the modern theory of Ricardian equivalence, which says that taxes and budget deficits are logically equivalent, Barro summarizes the current debate and argues that the Ricardian theorem is the correct starting point for the analysis of intertemporal government finance. Finally, stating his belief that macroeconomists have probably spent too much time thinking about deficits—which relate to how government spending is financed—and not enough about the effects of government expenditures themselves, he examines evidence of the macroeconomic effects of government spending in the United States and Great Britain.

Economists and the governments they advise have based their macroeconomic policies on the idea of a natural rate of unemployment. Government policy that pushes the rate below this point—about 6 percent—is apt to trigger an accelerating rate of inflation that is hard to reverse, or so the argument goes. In this book, Storm and Naastepad make a strong case that this concept is flawed: that a stable non-accelerating inflation rate of unemployment (NAIRU), independent of macroeconomic policy, does not exist. Consequently, government decisions based on the NAIRU are not only misguided but have huge and avoidable social costs, namely, high unemployment and sustained inequality.

Skillfully merging theoretical and empirical analysis, Storm and Naastepad show how the NAIRU’s neglect of labor’s impact on technological change and productivity growth eclipses the many positive contributions that labor and its regulation make to economic performance. When these positive effects are taken into account, the authors contend, a more humane policy becomes feasible, one that would enhance productivity and technological progress while maintaining profits, thus creating conditions for low unemployment and wider equality.

It is now widely agreed that mainstream macroeconomics is irrelevant and that there is need for a more useful and realistic economic analysis that can provide a better understanding of the ongoing global financial and economic crisis. Lance Taylor’s book exposes the unrealistic assumptions of the rational expectations and real business cycle approaches and of mainstream finance theory. It argues that in separating monetary and financial behavior from real behavior, they do not address the ways that consumption, accumulation, and the government play in the workings of the economy.

Taylor argues that the ideas of J. M. Keynes and others provide a more useful framework both for understanding the crisis and for dealing with it effectively. Keynes’s basic points were fundamental uncertainty and the absence of Say’s Law. He set up machinery to analyze the macro economy under such circumstances, including the principle of effective demand, liquidity preference, different rules for determining commodity and asset prices, distinct behavioral patterns of different collective actors, and the importance of thinking in terms of complete macro accounting schemes. Economists working in this tradition also worked out growth and cycle models.

Employing these ideas throughout Maynard’s Revenge, Taylor provides an analytical narrative about the causes of the crisis, and suggestions for dealing with it.

Innovative new approaches for improving GDP measurement to better gauge economic productivity.

Official measures of gross domestic product (GDP) indicate that productivity growth has declined in the United States over the last two decades. This has led to calls for policy changes from pro-business tax reform to stronger antitrust measures. But are our twentieth-century economic methods actually measuring our twenty-first-century productivity?

The Measure of Economies offers a synthesis of the state of knowledge in productivity measurement at a time when many question the accuracy and scope of GDP. With chapters authored by leading economic experts on topics such as the digital economy, health care, and the environment, it highlights the inadequacies of current practices and discusses cutting-edge alternatives.

Pragmatic and forward-facing, The Measure of Economies is an essential resource not only for social scientists, but also for policymakers and business leaders seeking to understand the complexities of economic growth in a time of rapidly evolving technology.

Here is a clear and thoughtful introduction to the current literature of monetary economics and macroeconomics. The book's central theme is a view of the macroeconomy in which recession and inflation are to be interpreted as the result of the economy adjusting to a discrepancy between the quantity of money supplied and the quantity of money demanded, with the latter quantity being determined by a stable aggregate demand function.

The author discusses in turn the place of monetarism in macroeconomics, its implications for the interpretation of the short-run demand for money function, its relationship to equilibrium business cycle theory, the disequilibrium transmission mechanism that underlies the monetarist viewpoint, and finally its implications for the policy of “gradualism.” He synthesizes a large body of theoretical and empirical literature, and his empirical observations are broadly based on the experiences of England and Australia as well as Canada and the United States. Each chapter can be read apart from the others, and Laidler has taken particular care to keep the technical level of exposition low without sacrificing much in the way of theoretical sophistication.
