These notes review two simple heterogeneous agent models in economics and finance. The first is a cobweb model with rational versus naive agents introduced in Brock and Hommes (1997). The second is an asset pricing model with fundamentalists versus technical traders introduced in Brock and...

This paper investigates whether the observed “momentum effect” in individual stocks, caused by positive serial correlations in returns over short horizons, can be explained by fundamentalists’ heterogeneous beliefs when chartists are present in the market. For this purpose, we propose a...

In a market economy, the aggregate production level depends not only on the aggregate variables but also on the distribution of individual characteristics (e.g., productivity, credit limit, .). We point out that, due to financial frictions, the equilibrium aggregate production may be...

The capital market is a reflexive dynamical input/output construct whose output (time series) is usually assessed by an index of roughness known as Hurst’s exponent (H). Oddly enough, H has no theoretical foundation, but recently it has been found experimentally to vary from persistence (H ...

This article tries to solve the portfolio inflation hedging problem by introducing a new class of dynamic trading strategies derived from classic portfolio insurance techniques adapted to the real world. These strategies aim at yielding higher returns on a risk-adjusted basis than regular...

Under the background of the electronic security trading platform Xetra operated by Frankfurt Stock Exchange, we consider the Xetra auction market system (XAMS) from `bottom-up', which the interaction among heterogeneous traders and Xetra auction market mechanism generates non-equilibrium price...
