Abstract:
– This paper examines the phenomenon of the underground economy. We analyze the choice by firms and workers to carry out their economic activities within the formal economy context (regular economy) or the underground economy context (irregular economy). We assume that there are two types of labor markets, a regular one, and a irregular one; and starting from a coordinated interaction between the firm and the worker we show the existence of multiple symmetric equilibria in each market. The proposed game of coordination (2x2), can be interpreted as a pre-contract interaction between the agents through which they determine in which labor market they will “meet”. In the model, we insert an exogenous policy parameter (t) that measures the impact of legislative policy interventions on the regular labor market. The parameter takes on a positive value with respect to those interventions that increase the incentives to operate in the regular market. Through the utilization of evolutionary dynamics we can explicate the mechanism that leads the system towards one of the two equilibria, and explain the fact that these equilibria are sustained among the different populations (firms and workers) by taking on the role of a social norm. In this framework, we show that policy interventions (t) do not alter the choice dynamics of each actor, nor do they eliminate the probability of having certain dynamics that push the system towards the underground market, even where there are strong incentives for acting in the regular economy.
