This paper analyzes the macroeconomic consequences of the establishment of a monetary union in the presence of unionized labour markets. It is shown that the effects of the formation of a monetary union depend on several labour market features, such as the degree of centralization of wage...

Existing theories of unions emphasize their impact on wage levels relative to the opportunity cost of leisure. This paper explores the possibility that monopoly unions provide income insurance against idiosyncratic wage variability. An optimal union contract is characterized by real wage and...

In this paper I analyse a labour market where the wage is endogenously determined according to an Efficient Bargaining process between a firm and a labour union whose members are partitioned into two social groups: the old and the young. Furthermore, I exploit the Single-Mindedness theory, which...

In a unionized Cournot duopoly under decentralized wage bargaining regime, we analyzed undeclared labour in a matrix game. We reveal the opportunity cost between taxation and contributions for social insurance that firms and unions face, while we examine all relevant possible unilateral...

Undeclared labour constitutes a complex phenomenon that has not yet been analyzed within I/O framework. In a unionized duopoly under decentralized wage bargaining context, we reveal the opportunity cost that exists between the taxation and the contributions for social insurance. Comparing to a...

In a duopoly where firms are competing by adjusting their quantities and the wages are exogenously determined, we analyze the undeclared labour phenomenon and its side effects in product market. Our analysis focuses on the opportunity cost between the taxation and the contributions for social...

In a union-duopoly strategic context, we explore the endogenous determination and the effects of the unionization structure in a market facing the possibility of inward foreign direct investments (FDI). We focus our analysis on the role of the reservation wages in home and foreign market and...

In a union-oligopoly context, we interpret the optimal equilibria may arise from the implementation of any possible policies of a benevolent social planner in the labour market. The applied policies may contradict or correspond with unions' and firms' objectives, while in other cases...
