A Schumpeterian process of creative destruction can induce a rational herd behavior by entrepreneurs across various sectors of the economy that may look like it is fuelled by "animal spirits." Across cyclical economies, a negative relationship emerges between volatility and growth, and the...

We present a class of convex endogenous growth models and analyze their performance in terms of both growth and business cycle criteria. The models we study have close analogs in the real business cycle literature. We interpret the exogenous growth rate of productivity as an endogenous growth...

We develop a stylized two-sector business cycle model with endogenous firm dynamics in the investment goods sector. The positive correlation between firms' profitability and the relative price of investment goods generates an endogenous persistence mechanism in productivity dynamics which drives...

The author shows that the enormous gap between theory and facts in modern macroeconomics can only be eliminated by nonlinear macroeconomic dynamics with the following special characteristics: First of all, only certain group-theoretical invariants generate the correct growth cycles with...
