We incorporate a renewable resource into an overlapping generations model without capital and with quasi-linear preferences. Besides being an input for production the resource serves as a store of value. We characterise the dynamics, efficiency and stability of the steady state equilibria. The...

We study the implications of product and labor market imperfections for equilibrium unemployment under both exogenous and endogenous capital intensity. With endogenous capital intensity, stronger labor market imperfections always increase equilibrium unemployment. The relationship between the...

We analyze the impact of progressive taxation on irreversible investment under uncertainty. We show that if tax exemption is lower than sunk cost, higher tax rate will decelerate optimal investment by increasing the optimal investment threshold, while if tax exemption exceeds sunk cost, three...

We analyze optimal harvesting policy under stochastic price and stock dynamics. We state a set of weak conditions under which the optimal policy can be characterized by a single exercise threshold and show that the value of optimal harvesting and depletion policies can be expressed as the...

We use a Wicksellian single rotation framework to analyze the impact of the intertemporally fluctuating and stochastic mean-reverting interest rate process on the optimal harvesting threshold and thereby the expected length of the rotation period, when forest value is also stochastic following...

We investigate the implications of product market imperfections on profit sharing, wage negotiation and equilibrium unemployment. The optimal profit share, which the firms use as a wage-moderating commitment device, is below the bargaining power of the trade union. Intensified product market...

We study employment, employee effort, wages and profit sharing when firms face stochastic revenue shocks and when base wages and profit shares are determined through negotiations. The negotiated profit share depends positively on the relative bargaining power of the trade union and it has...

We investigate the interaction between labour and credit market imperfections for equilibrium unemployment in the presence of profit sharing. In a partial equilibrium with exogenous outside options increased bargaining power of banks has adverse employment effects. In a general equilibrium with...

We study the implications of product market competition and investment for price setting, wage bargaining and thereby for equilibrium unemployment in an economy with product and labour market imperfections. We show that intensified product market competition will reduce equilibrium unemployment,...

We study the various consequences of and the incentives for outsourcing. We argue that the wage elasticity of labour demand increases as a function of the share of outsourcing, which is a result consistent with existing empirical research. Furthermore, we show that a production mode with a...
