| Abstract: | We investigate in a horizontal product differentiation model with North-South trade the implications of a home bias in consumers' demand for labelled goods. We compare mutual recognition and international harmonisation of ecological labels with respect to firms' profits and welfare. Northern consumers perceive a warm glow from buying green, but have information problems with imported labelled products. Firms differ in labelling costs which could help a Southern firm to compensate for the home bias under mutual recognition. Under harmonisation the home bias disappears. Welfare analysis of harmonised labelling shows that a Southern firm gains from adopting a harmonised label - even if there is "eco-imperialism". Given the specific trade structure in our model, harmonisation is a beneficial regime except for the case that labelling costs reach a specific treshold. |

| Abstract: | This paper argues that tourism will become a major activity in a modern welfare state, which will have serious consequences for environmental sustainability. This issue calls for an assessment of the pros and cons of the ecological efficiency of tourism. We propose an overall efficiency indicator that comprises both a sustainable tourism index and an economic efficiency index. Based on a data set for Italian provinces and using Activity Analysis, a quantitative assessment of the relative position of Italian tourist destination areas is made from the perspective of sustainable tourism. |

| Abstract: | AIn this paper we use mechanism design approach to find the optimal file-sharing mechanism in a peer-to-peer network. This mechanism improves upon existing incentive schemes. In particular, we show that peer-approved scheme is never optimal and service-quality scheme is optimal only under certain circumstances. Moreover, we find that the optimal mechanism can be implemented by a mixture of peer-approved and service-quality schemes. |
| Keywords: | peer-to-peer networks, mechanism design. |
