To Work or Not? Simulating Inspection Game with Labor Unions
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, the performance of the firm is significantly deteriorated and its existence endangered. On the other hand, the inspection proved to be a successful method for “motivating” employees to work. By using non-omniscient agents, we also estimated the cost of that non-omniscience, which proved to be significant in all cases.social networks, inspection game, evolutionary games
A Repeated Game Heterogeneous-Agent Wage-Posting Model
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 competitor. However, it is a less productive employer whose wage posting could also outweigh the posting of a more productive employer, though only temporarily.Job-search model; Wage posting; Heterogeneous agents; Numerical optimization
Homogenous Agent Wage-Posting Model with Wage Dispersion
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 significantly prolongs the convergence-time to the equilibrium, and, more importantly, it may lead to the wage dispersion, irrespective of equally-productive-agent proposition, something not present in the model of Montgomery.Job-search model, wage posting, wage dispersion, numerical optimization
Credit Contagion in Financial Markets: A Network-Based Approach
We propose a network-based model of credit contagion and examine the e�ects of idiosyncratic and systemic shocks to individual banks and the banking system. The banking system is built as a network in which banks are connected to each other through the interbank market. The microstructure captures the relation between debtors and creditors, and the macroeconomic events capture the sensitivity of the banks' �nancial strenght to macroeconomic events, such as housing. We have demonstrated that while idiosyncratic shocks do not have a potential to substantially disturb the banking system, macroeconomic events of higher magnitudes could be highly harmful, especially if they also spur contagion. In a concerted default of more banks, the stability of a banking system tends to decrease disproportionately. In addition, credit risk analysis is highly sensitive to the network topology and exhibits a nonlinear characteristic. Capital ratio and recovery rates are two additional factors that contribute to the stability of the �nancial system
