The potential interactions among fiscal policies, investments and economicgrowth are complex and manifold.In this paper, we will perform a systematic comparative analysis of the variouseconomic insights that arecurrently available on these complex relationships, both theoretically (by aselective...

This paper shows that the introduction of a minimum quality standard can have repercussions on market structure, opening the possibility of predatory behaviour. The predatory equilibrium exists independently of whether or not adjustment costs are present. Moreover, whenever predation is an...

This paper introduces and surveys ecological-economic analysis and valuation of biodiversity. Furthermore, the notion and application of economic, monetary valuation of biodiversity is critically evaluated. A classification of biodiversity values is offered, based on a system of logical...

We investigate dynamic R&D for process innovation in an oligopoly where firms invest in cost-reducing activities. We focus on the relationship between R&D intensity and market structure, proving that the industry R&D investment monotonically increases in the number of firms. This Arrowian result...

This paper describes R&D competition between a managerial firm and an entrepreneurial one, in a Cournot market. It is shown that a manager interested in output expansion exerts higher R&D efforts, yielding productive efficiency as compared to the performance of a strictly profit-seeking firm....

I investigate R&D efforts for process innovation in a monopoly with uncertain demand. Two different models are proposed, where either (i) the reservation price is affected by an additive shock and the marginal production cost is increasing, or (ii) a multiplicative shock on the slope of demand...

We reassess the respective gains from R&D cooperation and competition in a Cournot Duopoly with homogeneous goods, where firms adopt a concave cost-reducing R&D technology. Contrary to the previous literature on the same topic, our main results are that (i) no corner solutions emerge and (ii)...

We investigate the bearings of network externalities on product quality improvements requiring costly R&D investments. The model considers the dynamic behaviour of a monopolist alternatively maximising profits or social welfare. On the one hand, we confirm much of the acquired wisdom from the...

We investigate dynamic R&D for process innovation in an oligopoly where firms invest in cost-reducing activities. We focus on the relationship between R&D intensity and market structure, proving that the industry R&D investment monotonically increases in the number of firms. This result...

We investigate the timing of adoption of product and process innovation by using a differential game in which firms may invest in both activities. We consider horizontal product innovation that reduces product substitutability, and process innovation that reduces marginal cost. First, we...
