This book offers insight into the current developments in mathematical economics. The book is intended for a broad audience and technicalities are kept to a minimum. The issues addressed include general equilibrium, price competition, auctions, environmental policy, networks, dynamic (in)stability and bounded rationality. Moreover, the book contains a survey and appraisal of the work of Claus Weddepohl, to whom the volume is dedicated. In his academic career, Claus Weddepohl made important contributions to the development of mathematical economics. He did so in his own writings on general equilibrium theory, the theory of markets and on economic dynamics. He was also a stimulating teacher and inspired the scientific research of many of his colleagues

We develop the first agent-based model (ABM) that can compete with and in the long run significantly outperform benchmark VAR and DSGE models in out-of-sample forecasting of macro variables. Our ABM for a small open economy uses micro and macro data from national sector accounts, input-output tables, government statistics, and census data. The model incorporates all economic activities as classified by the European System of Accounts as heterogeneous agents. The detailed structure of the ABM allows for a breakdown into sector level forecasts. Potential applications of the model include stress-testing and predicting the effects of monetary or fiscal macroeconomic policies.
