...In the words of Ira Adelman (1960), she and her husband had not "proved that business cycles are stochastic in origin" though they had presented evidence creating "a strong presumption in favour of this hypothesis" which would be "especially significant in view of the absence (to date) of a completely satisfactory endogenous theory of business cycles." The view that business cycles are exogenously determined by random shocks strongly influenced economics in the 1960s and 1970s. Indeed, disputes between Keynesian and monetarist authors during the period of decline of Keynesian economics can be seen as arguments about which parts of the propagation mechanism are either actually working, or the most important for the dynamics of the economy. These disputes were later superseded by rational expectations and assumptions about the intertemporal substitution of leisure for labor. We arrive to the views of late 20th century macroeconomists supporting the realbusiness-cycle (RBC) theory who conceptualize business cycles as the consequence of a self-equilibrating economy responding to random events affecting aggregate supply. They often mention, in the tradition of Schumpeter and Hayek, technological innovations or “shocks” as causes of economic fluctuations. Other exogenous factors such as demographic changes, political influences, or variations in relative prices have been also proposed. This type of “supply shocks” is often referred to without specifying its nature, though for instance James Hamilton (1988, 1994) proposed changes in oil prices as a key determinant of recessions. Nowadays, however, economists supporting a theory of business cycles determined by exogenous factors—Austrians, monetarists, RBC theorists— are probably a minority compared to economists who view the fluctuations of the market economy as mainly determined by endogenous factors—Samuelsonians, Keynesians, new-Keynesians, postKeynesians, institutionalists and socialist economists.2 At any rate, as Thomas E. Hall put it twenty years ago, it is important to keep in mind the distinction between endogenous and exogenous theories, “because they imply a very different behavior for an economy.” Those supporting exogenous factors as causes of the business cycle tend “to view economies as being inherently stable but shocked by outside forces” while endogenous theorists “generally consider economies as being inherently unstable and subject to selfgenerating cycles. This distinction in macroeconomics is very old and exists today between the monetarists (primarily exogenous) and Keynesians (primarily endogenous)” (Hall, 1990:10). Wages are a key variable explaining recessions for many economists. However, authors agreeing with this claim adhere to quite different schools of thought and have proposed diverse, indeed opposite mechanisms to explain why changes in wages would cause economic downturns. Both too high or too low wages have been viewed as causes of recession. In the view of Arthur Pigou (1927) presented recently for example by Lee Ohaniann (2008), a qualified representative of the RBC school, it is too high wages that cause too high costs for business, with the consequent decay in economic activity leading to a downturn....
