- Abstract:
- There is a narrative within our field that macroeconomics has lost its way. While I have some sympathy with this narrative, I think it is a better description of the field 10 years ago than of the field today. Today, macroeconomics is in the process of regaining its footing. Because of this, in my view, the state of macroeconomics is actually better than it has been for quite some time. The most important problem with macro over the past few decades has been that it has been too theoretical. When I say this, I don‘t at all mean to say that theory is useless. To the contrary, theory is an essential element of a healthy science. But a healthy science needs a balance between theory and empirical work. Macro lost this balance in the 1980s and is only regaining it now. Most narratives about the evolution of macro focus on the evolution of macroeconomic theory and the rational expectations revolution in particular. An under-appreciated part of this story is that the rational expectations revolution shifted the field away from empirical work. This was partly because building models that met the higher standards of rigor set by Lucas and his co-revolutionaries was a challenging and therefore highly absorbing task. But that isn’t the only reason. For reasons that are not entirely clear to me, a very substantial fraction of macroeconomists came to believe that the Lucas critique implied that quasi-experimental empirical methods could not be used in macro. The idea that changes in policy could radically alter empirical regularities (i.e., the Lucas critique) somehow came to be interpreted to mean that the only way to do empirical work in macro was to write down fully specified general equilibrium models of the whole economy and evaluate the entire model (either by full-information inference methods or moment matching). Sargent, for example, placed enormous emphasis on the idea of “cross-equation restrictions.“ It seems that this line of thinking led large numbers of macroeconomists astray in terms of how to think about empirical work in macro for several decades.
