After decades of trial, error, and occasional regress the pieces of a successful Latin American economic model can be seen scattered among the leading economies of the region. The most traditional macroeconomic maladies of the emerging world - such as chronic fiscal imbalances and monetary...

In this paper I argue that the current core of macroeconomics--by which I mainly mean the so-called dynamic stochastic general equilibrium approach--has become so mesmerized with its own internal logic that it has begun to confuse the precision it has achieved about its own world with the...

One of the main economic villains before the crisis was the presence of large "global imbalances." The concern was that the U.S. would experience a sudden stop of capital flows, which would unavoidably drag the world economy into a deep recession. However, when the crisis finally did come, the...

The 90s have witnessed a revival in economists' interest and hope of explaining" aggregate and microeconomic investment behavior. New theories, better econometric" procedures, and more detailed panel data sets are behind this movement. Much of the progress" has occurred at the level of...

The simple permanent income model provides a good description of the medium-long run behavior of aggregate nondurables consumption, while it fails in describing its short run behavior. In this paper I present a non-representative agent model with near-rational microeconomic units that...

Aggregate expenditure on durable goods responds too slowly to wealth and other aggregate innovations to be consistent with the simplest frictionless version of PIH (permanent income hypothesis). In this paper I present a model of aggregate expenditure on durab1es that builds up from the lumpy...

The representative agent framework has endowed macroeconomists with powerful microeconomic tools. Unfortunately, it has also blurred the distinction between statements that are valid at the individual level from those that apply to the aggregate. In this paper I argue that probability theory...
