Why do economies grow? What fixes the long-run rate of growth? These are some of the simplest, but also hardest, questions in economics. Growth of lack of it has huge consequences for a country's citizens. But for various reasons, growth theory has had long fallow patches. Happily, this is changing. In 1956 Robert Solow developed what became the standard neo-classical model of economic growth. Counties grow, on this theory, by accumulating labour and capital. Adding either obeys diminishing returns: the more labour or capital you already have, the more you need for a further given jump in output. One consequence is that an economy with less capital ought to outgrow one with more. Generally, they do. Another is that growth should eventually drop to zero. Awkwardly, it stays positive. To save the theory, long-run growth was explained by an outside factor, technical innovation, which is not in the growth function itself—hence the label "exogenous" for the Solow family of models. Partial as it was, the Solow model won wide acceptance and growth theory slumbered for three decades. Then came two changes. One was an attempt to add technical change and other factors to labour and capital within the growth function so that the model might predict long-run growth without leaning on outside "residuals"—the so-called "endogenous" approach. The other was a huge number of factual studies. Barro and Sala-i-Martin explain all this and more with admirable clarity (and much demanding maths) in the first modern textbook devoted to growth theory. The main theories are examined. The stress throughout is on linking theory to fact. One of three chapters on empirical work suggests how much each of several possible factors would be needed to explain differing international growth rate—not an explanation itself, but an indispensable set of empirical benchmarks.

The new classical approach to macroeconomics, which assumes that people gather and use economic information efficiently, has been the most important theoretical advance since the Keynesian revolution of the 1930s. This hook surveys the major contributions of the "second generation" of proponents of the new classical approach, emphasizing real business cycle theories and applying them to a variety of phenomena. The chapters include expositions of growth theory, real models of business fluctuations, the informational role of prices, consumption, fiscal policy, rules versus discretion in monetary policy, time consistency and policy, and monetary models. Although the chapters are aimed at advanced undergraduate- and graduate-level students, they will also be of interest to researchers who are looking for a compact and original exposition of the new classical macroeconomics.
