This paper studies optimal investment and dynamic behaviour of stochastically growing economies. We assume neither convex technology nor bounded support of the productivity shocks. A number of basic results concerning the investment policy and the Ramsey–Euler equation are established. We also...

Within a one-sector, infinite-horizon representative agent model with technological externalities and a convex-concave production function, this paper derives a capital subsidy policy that simultaneously eliminates the wedge between private and social marginal products of capital, and achieves a...

We consider optimal fishery management under the assumption of increasing returns that is supported by previous empirical evidence. We improve the tractability and realism of the previous approaches by introducing flow adjustment costs on changes in harves rate. Our framework is the first to...

Part of the existing economic literature on fisheries regulation focuses on addressing several objectives with one instrument. In an extension of this literature we investigate the following three objectives of fisheries regulation: A) Correcting a stock externality; B) Raising public funds, and;...
