Casual empiricism suggests that “unwarranted” wage changes, defined as the part of wage growth that is not explained by changes in labour productivity, are negatively associated with the return on capital. The main point of this paper is to show that “unwarranted” wage changes have no...

The value of the elasticity of substitution between labor and capital (ó) is a “crucial” assumption in understanding the secular decline in labor share of income (Piketty (2014a), Karabarbounis and Neiman (2014)) and long-run growth (Solow, 1956). This paper begins by examining the role of...

Weakening bargaining power of unions and the increasing integration of the world economy may affect the volatility of capital and labor incomes. This paper documents and explains changes in income volatility. Using a theoretical framework which builds distribution risk into a real business cycle...

Recent criticism from different sides has expressed the view that, with scarce resources, there is little justification for massive public funding of higher education. Central to the debate is the conjecture that colleges and universities use their resources inefficiently and focus...

Using a heterogeneous agent model allowing for different degrees of complementarity between capital, skilled and unskilled labour, this paper evaluates supply-side reforms consistent with lower public debt-to-GDP in the long-run. We find that, relative to the other tax reforms, capital tax cuts...

We evaluate the effects of outsourcing and wage solidarity on wage formation and equilibrium unemployment in a heterogeneous labour market, where wages are determined by a monopoly labour union. We find that outsourcing promotes the wage dispersion between the high-skilled and low-skilled...

We analyze the following questions associated with flexible outsourcing under partly imperfect dual domestic labour markets, where high skilled workers participate in firm’s profit via profit sharing: How does the implementation of profit sharing influence flexible outsourcing? What is the...

The average height of children is an indicator for the quality of nutrition and health care. Heights have never declined over longer time spans in Eastern Germany since 1880 – except for the most recent period 1997-2006. In the Eastern German Land of Brandenburg, a data set of 253,050...

We analyze the questions associated with flexible outsourcing both with committed and flexible profit sharing under imperfect domestic labour markets. How does profit sharing influence flexible outsourcing? What is the relationship between outsourcing cost, profit sharing and equilibrium...

The impacts of introducing work requirements for welfare recipients are studied in an efficiency wage model. If the workfare package is not mandatory, it will reduce employment, profits, and utility levels of employed and unemployed workers. In contrast, mandatory effort requirements will...
