We propose a network-based structural model of credit risk to demonstrate how idiosyncratic and systemic shocks propagate across the banking system and evaluate the costs. The banking system is built as a network of heterogeneous banks which are connected with one another. In such a system,...

In the paper we simulate a heterogeneous-agent version of the wage-posting model as derived by Montgomery (1991) with homogeneous workers and differently-productive employers. Wage policy of particular employer is positively correlated with employer's productivity level and the wage policy of...

The paper provides methodologically new approach to pricing CDS, predicated on the banking network and the banks' balance sheets. The model is evolutionary and includes a counterparty risk and the central bank bailout policy. The banking network is used to accurately calculate the capital ratio...

The paper is an examination of the interaction-based approach in economics and finance. The economy is considered a complex adaptive system that consists of a large number of interacting units who are represented as software bits of data and the rules of conduct. Heterogeneity, evolution,...

The model of social network is used to analyze the impact of the power of labor unions in the labor relations. We find that labor union capable to affect a pecuniary compensation of shirking employees lessens the motivation of employees to work and improve to the unionization rate. As a result,...

In the paper, we simulate a heterogeneous-agent version of the wage-posting model as derived by Montgomery (1991) with homogeneous workers and differently-productive employers. Wage policy of particular employer is positively correlated with employer’s productivity level and the wage policy of...

In the paper we test a homogenous agent version of the Montgomery's (1991) non-cooperative wage posting model. The inclusion of intrinsic costs, related to the uncertainty when changing the alternative agents are already using, alters the outcome of the model in two respects: firstly, it...

We challenge the hypothesis of the efficient frontier portfolios by using network approach. In a small-world network interacting agents decide upon the portfolio selection solely upon past returns. Simulation results indicate that agents are capable of forming the efficient frontier, whereas...
