In a dynamic model of a risk-neutral competitive firm which can lower its pollution emissions per unit of output by building up abatement capital stock, we examine the effect of a higher pollution tax rate on abatement investment both under full certainty and when the timing or the size of the...

This paper analyses the issue of money superneutrality through an intertemporal optimising model of capital accumulation and inflation with endogenous fertility, i.e. endogenous population growth. The model establishes an inverse relation between capital-labour ratio and population growth, which...

In this paper we explain the apparent ''diversification discount'' of conglomerates without assuming inefficient-cross subsidisation through internal capital markets. Instead we assume that an internal capital market efficiently redistributes scare resources across a conglomerate's divisions...

Non-strategic firms with rational expectations make investment and emissions decisions. The investment rule depends on firms' beliefs about future emissions policies. We compare emissions taxes and quotas when the (strategic) regulator and (nonstrategic) firms have asymmetric information about...

This paper shows that the assumption of elastic fertility choices represents an unconsidered way of introducing nondegenerate dynamics within an immortal small open economy, facing perfect capital mobility and no adjustment costs associated with capital accumulation, and having a fixed discount...

Recent developments in investment research have highlighted the importance of non-convexities and irreversibilities in the firms' adjustment of quasi-fixed inputs. However, aggregation across capital goods may smooth out the discontinuities associated with the adjustment of individual assets....

This paper analyzes the effects of a land rent tax on capital formation and foreign investment in a life-cycle small open economy with endogenous labor-leisure choices. Differently from the previous literature, the consequences of land taxation critically depend on how the tax proceeds are used...

In this article we analyse the effects of different regulatory schemes (price cap and profit sharing) on a firm's investment of endogenous size. Using a real option approach in continuous time, we show that profit sharing does not affect a firm's start-up decision relative to a pure price cap...

The consequences of government debt on capital formation, financial wealth and labor are investigated in a small open economy with demographic heterogeneity. Two alternative types of demographics are considered: one with intragenerational heterogeneity of the ''savers-spenders'' (SS) type, and...

In this paper, we study the effect of share issue privatization (SIP) on private investment and financial market under incomplete risk diversification. Risk neutrality and imperfect intertemporal substitutability make investment decreasing in privatization (crowding-out effect). Vice-versa with...
