In this paper, I present a theory of dynamic economic growth, business cycles, and asset pricing that integrates (1) Marx's idea (and emphasized by Klein) of a two-class heterogeneity of the ownership structure of physical capital and human capital in a capitalist society, (2) Keynes' idea of...

Building a model with three imperfect markets – goods, labor and credit – representing aproduct’s life-cycle, we find that goods market frictions drastically change the qualitative andquantitative dynamics of labor market variables. The calibrated model leads to a significantreduction in...

Unemployment may depend on equilibrium in other markets than the labor markets. Thispaper adresses this old idea by introducing search frictions on several markets: in a model ofcredit and labor market imperfections as in Wasmer and Weil (2004), I further introducesearch on the goods market. The...

The paper examines questions of local asymptotic stability of randomdynamical systems. Results concerning stochastic dynamics ingeneral metric spaces, as well as in Banach spaces, are obtained. Theresults pertaining to Banach spaces are based on the linearization ofthe systems under study. The...

Considered here is on-line portfolio management aimed at maximizing the long-run growth of financial wealth. The portfolio is repeatedly rebalanced in response to observed returns on diverse assets. Suppose statistical information and related methods are not available - or deemed too diffcult....

The paper examines a dynamic model of a financial market with endogenous asset prices determined by short run equilibrium of supply and demand. Assets pay dividends that are partially consumed and partially reinvested. The traders use fixed-mix investment strategies (portfolio rules),...

This paper extends the class of stochastic AK growth models with a closed-formsolution to the case where there are two capital goods in the model. To be precise,we consider the Uzawa-Lucas model of endogenous growth with human and physical capital. The extension holds, even if an external effect...

Rejuveniles are "grown-ups who cultivate juvenile tastes in products and entertain-ment". In this note, we study a standard AK growth model of overlapping gener-ations populated by rejuveniles. For our purposes, rejuveniles are old agents whoderive utility from "keeping up" their consumption...

This paper extends and modifies the Keynesian critique of inflation targetingwith reference to stabilisation policy in emerging market economies. The IMF‘basic monetary programming framework’ for developing countries usesgovernment borrowing and the exchange rate as policy instruments in...

A simple asset pricing model with two types of adaptively learning traders, fundamentalists and technical analysts, is studied. Fractions of these trader types, which are both boundedly rational, change over time according to evolutionary learning, with technical analysts conditioning their...
