The effect of membership rules and voting schemes on the success of international climate agreements

We empirically test the role of membership rules and voting schemes for climate change coalitions with the STAbility of COalitions model (STACO). The model comprises twelve world regions and captures long-run effects of greenhouse gas accumulation. We apply three stability concepts that capture the notion of open membership and exclusive membership with majority and unanimity voting. We show that exclusive membership leads to superior outcomes than open membership and that unanimity voting is preferable to majority voting in welfare and environmental terms. Our results suggest restricting membership in future international environmental agreements and they provide a rationale for unanimity voting as applied in many international organizations.     

Bolivia's soy complex: the development of ‘productive exclusion’

A significant transition is underway in Bolivia where both domestic and foreign capital are monopolizing commercial agriculture and leading a highly mechanized, capital-intensive production model which has considerably diminished the need for labour. This paper explores mechanisms and processes of ‘productive exclusion’ in the soy-producing zones of Santa Cruz in relation to the expansion, concentration and mechanization of the ‘soy complex’. We provide an analysis of how the agrarian structure has developed since soy was adopted – from ‘putting land into production’ to ‘expanding the agricultural frontier’ and ‘controlling the agro-industrial chain’. We explore how and the extent to which the penetration of new capital is leading to new processes of agrarian change which exclude the rural majority from accessing the means of production. While a process of ‘foreignization’ of land began to take shape in the early 1990s, new processes of capital accumulation are eroding the ability of small farmers to engage in productive activity, potentially leading to ‘surplus’ populations no longer needed for capital accumulation.     

Plain tales from the rice trade: Indications of vertical integration in foodgrain markets in Bangladesh

Through a series of case studies of the interactions between foodgrain traders and between traders and producers, this article questions the widespread belief that foodgrain markets in Bangladesh are characterised by low trading margins, no vertical integration and a general competitive health. The article indicates that merchant's capital plays two key roles in the market (i) in some areas of the country, the provision of merchant's credit deprives the poor producer of access to the market price for his or her output; (ii) working capital extended to subordinate traders may also enable a small group of large traders to influence prices. Further case studies of the interaction between traders and the state food distribution system indicate ways in which the private market may be able to frustrate or limit policies intended to regulate its operation. These insights suggest that the domination of merchant's capital may be one factor explaining low levels of productivity in the Bangladesh countryside. They also raise questions about the consequences of policies intended to increase the role of private trade in the economy.
