This paper studies in the presence of flexible outsourcing the effects of outsourcing costs, productivity of outsourcing, wage tax and tax exemption in an imperfectly competitive labour markets when labour unions and firms negotiate wages and the impacts of labour tax progression on domestic...

It is analyzed the impacts of outsourcing cost and wage tax progression under labor market imperfections with Nash wage bargaining and flexible outsourcing. With sufficiently strong (weak) labor market imperfection, lower outsourcing cost has a wage-moderating (wageincreasing) effect so that...

Within an efficiency wage framework, we study the effects of two revenue-neutral tax reforms that change the progressivity of the labour tax system. A revenue-neutral increase in both the wage tax and tax exemption and a revenue-neutral change in the composition of labour taxation towards the...

What are the impacts of labor tax reform on wage setting and employment to keep the relative tax burden per low-skilled and high-skilled workers constant in the case of heterogeneous domestic labor markets, i.e. imperfect competition in low-skilled labor and perfect competition in high-skilled...

How much additional tax revenue can the government generate by increasing the level of labor income taxes? In this paper, we argue that the degree of tax progressivity is a quantitatively important determinant of the answer to this question. To make this point, we develop a large scale...
