It is common amonst macroeconomists to view aggregate investment fluctuations as a rational response to fluctuating incentives, driven by exogenous movements in total factor productivity. However, this approach raises a number of questions. Why treat investments in physical capital as...

The one-sector neoclassical growth model (Solow, 1956,RES) can generate only simple dynamics. The dynamic properties of the Solow model follow from the saving behaviour and the neoclassical technology. As shown by Day (1982, AER), when average savings are allowed to vary, the discrete-time...

The existing literature on the stabilizing properties of interest-rate feedback rules has stressed the perils of linking interest rates to forecasts of future inflation. Such rules have been found to give rise to aggregate fluctuations due to self-fulfilling expectations. In response to this...

The paper reconsiders an influential model by Blanchard (1981) that extends the textbook ISLM framework by including among the financial assets, besides money and short-term bonds, also long-term bonds and equities. Aggregate demand is supposed to vary with Tobin's (average) q, rather than the...

The literature on financial imperfections and business cycles has focused on propagation mechanisms. In this paper we model a pure reversion mechanism, such that the economy may converge to a two-period equilibrium cycle. This mechanism confirms that financial imperfections may have a dramatic...
