The authors incorporate a renewable resource into an overlapping generations model with standard, well behaved utility and constant returns to scale production functions. Besides being a factor of production the resource serves as a store of value. They characterize dynamics, efficiency and...

We consider the issue of steady-state optimal factor taxation in a Ramsey-type dynamic general equilibrium setting with two distinct distortions: i) taxes on capital and labour are the only available tax instruments for raising revenues, and ii) labour markets are subject to a static...

The current extensive literature on irreversible investment decisions makes the assumption of constant interest rate. In this paper we study the impact of interest rate and revenue variability on the decision to carry out an irreversible investment project. Given the generality of the considered...

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 consider a two-period overlapping generations model in which individual voters differ by age and by productivity, In such a setting, a redistributive Pay-As-You-Go system is politically sustainable, even when the interest rate is larger than the rate of population growth. The workers with...

According to the existing literature, capital taxes should not be imposed in the presence of optimal profit taxation in either unionised or competititive labour markets. We show that this conclusion does not hold for an economy with both competitive and unionised sectors, where the competitive...

We investigate the interaction between labour and credit market imperfections for the determination of equilibrium unemployment within the framework of the "right-tomanage" approach. Our analysis highlights the critical role of labour mobility for the evaluation of the employment implications of...

We analyze the impact of entrepreneurship as an outside option on compensation contracts between a principal and an agent with bargaining power. In the first stage the parties bargain over the base wage and the profit share. In the second stage the principal determines the capital investment and...

We study the role of labour and credit market imperfections for the determination of equilibrium unemployment. In the credit market loan contracts are negotiated between financiers and firms, both possessing bargaining power, while the firms and organized labour bargain over the base wage. The...
