Since 2010, U.S. GDP growth has been anemic, averaging 2.1% a year, and this despite interest rates very close to zero. Historically, one would have expected such low sustained rates to lead to much stronger demand. They have not. For a while, one could point to plausible culprits, from a weak...

The low-frequency movements of many economic variables play a prominent role in policy analysis and decision-making. We develop a robust estimation approach for these slow-moving trend processes, which is guided by a judicious choice of priors and is characterized by sparsity. We present some...

We investigate the fundamental determinants of sustainability in general equilibrium. We adopt a definition of sustainability that requires that the welfare of future generations is not expected to decrease on average. We then use a stochastic growth model to explore the conditions under which...
