The New Trade Theory predicts that international trade lowers prices for consumers and expands the choices available to them. This study shows that both predictions may no longer hold once adjustments in the retail sector are taken into account. I present a new model of retailing in general...

The paper proposes an elementary agent-based asset pricing model that, invoking the two trader types of fundamentalists and chartists, comprises four features: (i) price determination by excess demand; (ii) a herding mechanism that gives rise to a macroscopic adjustment equation for the market...

The unpredictability of returns counts as a stylized fact of financial markets. To reproduce this fact, modelers usually implement noise terms - a method with several downsides. Above all, systematic patterns are not eliminated but merely blurred. The present article introduces a model in which...

We develop a simple behavioral macro model to study interactions between the real economy and the stock market. The real economy is represented by a Keynesian goods market approach while the setup for the stock market includes heterogeneous speculators. Using a mixture of analytical and...

This article explores the influence of competitive conditions on the evolutionary fitness of different risk preferences. As a practical example, the professional competition between fund managers is considered. To explore how different settings of competition parameters, the exclusion rate and...

Tax and social reforms aiming at lowering the tax burden and cutting social benefits may boost effciency and output, and improve market adjustment to shocks. But they may also reduce the impact of automatic stabilizers and so cause a less cyclical smoothing. This is problematic in the Economic...

Several empirical studies are concerned with measuring the effect of currency and current account crises on economic growth. Using different empirical models this paper serves two aspects. It provides an explicit assessment of country specific factors influencing the costs of crises in terms of...

In the framework of small-scale agent-based financial market models, the paper starts out from the concept of structural stochastic volatility, which derives from different noise levels in the demand of fundamentalists and chartists and the time-varying market shares of the two groups. It...
