Team-competition in multi-agent games is an important setting, where multi-agent actor-critic methods are the state-of-the-art methods. In many such scenarios, the roles for players naturally emerge, thus aiding in collaboration within the teams. However, exiting methods for the team-competition...

Despite the rapid development of electric vehicles (EVs), the limited range and accessibility of charging infrastructure are still obstacles to the development of EVs. At present, the Chinese government has made great efforts to set up charging piles and the most popular construction mode of...

What model features and calibration strategies yield a large average marginal propensity to consume (MPC) in heterogeneous agent models? Through a systematic investigation of models with different preferences, dimensions of ex-ante heterogeneity, income processes and asset structure, we show...

This paper presents the economic and philosophical findings from an agent-based simulation extending and generalizing Hotelling’s Law. The simulation can be used to study spatial competition and product differentiation in a one- or two-dimensional space and illustrates the effects of relaxing...

The heterogeneous agent model (HAM) is a powerful tool to study the stock price dynamics and stylized anomalies in financial markets. However, existing HAMs often focus on the one-asset scenario which makes them hard to apply for the empirical studies of asset pricing and portfolio selection. In...

On the capital market, as a result of company-specific news, price movements of stock corporations can be observed independent of overall market developments, which suggest the occurrence of a sudden risk event. In recent years, numerous concepts from statistical physics have been transferred to...
