chorus of the tragedy which plays on the world stage. The main thesis of our work is that,despite the triumphant rhetoric praising the merits of perfect competition, the global fields ofthe dysfunctional market system have mushroomed in what we call Warrant Economics forthe Free-Market...

This paper investigates whether the inherent non-stationarity of macroeconomic time series is entirely due to a random walk or also to non-linear components. Applying the numerical tools of the analysis of dynamical systems to long time series for the US, we reject the hypothesis that these...

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...

This paper estimates a trivariate two-factor conditional version of the Intertemporal CAPM of Merton (1973).

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...

Diese Studie untersucht, ob Veränderungen kurzfristiger Zinsen die Kosten liquider Mittel beeinflussen und somit über Preissetzungsentscheidungen der Firmen auf die Inflationsdynamik in Industrieländern wirken. Barth und Ramey (2001) haben zum Beispiel für die USA gezeigt, dass...

This paper asks whether tax cycles can represent the optimal policy in a model without any extrinsic uncertainty. I show, in an economy without capital and where labor is the only choicevariable (a Lucas-Stokey economy), that a large class of preferences exists, where cycles are optimal, as well...

This paper studies the joint business cycle dynamics of inflation, money growth, nominal and real interest rates and the velocity of money. I extend and estimate a standard cash and credit monetary model by adding idiosyncratic preference shocks to cash consumption as well as a banking sector....

We study the dynamic general equilibrium of an economy where risk averse shareholders delegate the management of the firm to risk averse managers. The optimal contract has two main components: an incentive component corresponding to a non-tradable equity position and a variable ’salary’...

This paper proposes a theory of investment fluctuations where the source of the oscillating dynamics is an agency problem between financiers and entrepreneurs. A central tenet of the theory is that investment decisions depend upon entrepreneurs’ initiative to select investment projects...
