We develop a model of international roaming in which mobile network operators (MNOs) compete both on the wholesale market to sell roaming services to foreign operators and on the retail market for subscribers. The operators own a network infrastructure only in their home country. To allow their...

Industrialists often claim that, by rendering firms unprofitable and hence forcing them out of business, stricter emissions standards reduce the industry output and competition. This paper considers situations where firms' pollution reduction increases the industry demand, but because of...

The paper explores the impact of a third-party product ecolabel (i.e. green label) on competition and the environment, and the firms' strategies during the negotiation of the minimum environmental requirements underlying a product's eligibility for the ecolabel. The introduction includes some...

Many voluntary agreements (VA's) fall under the European or Dutch cartel prohibition (Article 81 EC, Article 6 Mededingingswet). This paper starts with an abstract description of the relation between competition and environmental protection. Particular attention is paid to the role in this...

This paper studies a model where exclusive dealing (ED) can both promote investment and foreclose a more efficient supplier. While investment promotion is usually regarded as a pro-competitive effect of ED, our paper shows that it may be the very reason why a contract that forecloses a more...

In many industries it is quite common to observe firms delegating the production of essential inputs to independent ventures jointly established with competing rivals. The diffusion of this arrangement and the favourable stance of competition authorities call for the assessment of the social and...

This article constitutes a new contribution to the analysis of overlapping instruments to cover the same emission sources. Using both an analytical and a numerical model, we show that when the risk that the CO2 price drops to zero and the political unavailability of a CO2 tax (at least in the...

This paper examines the macroeconomic effects of an environmental tax reform in a growing economy. A model of endogenous growth based on human capital accumulation is used to numerically simulate the growth effects of different environmental tax reforms and compute their impact on welfare in the...

Eco-entrepreneurs in developing countries are often subject to market or institutional constraints, e.g. via credit rationing or missing markets. Conservation interventions which relax constraints may be both cost-effective and poverty reducing. A simulation using data from an intervention in...

Water resources are unevenly spread in China. Especially the basins of the Yellow, Hui and Hai rivers in the North are rather dry. To increase the supply of water in these basins, the South-to-North Water Transfer project (SNWT) was launched. Using a computable general equilibrium model this...
