Some perspectives of neo-institutional economics are used to reexamine the common pool fishery. Applications of properly rights theory in models simulating the evolution of fisheries management suggest that even in the presence of positive information and transactions costs (ITCs), resource...

Rice sector contributes significantly to secure households with regard to their food needs but also to the creation of employments and income generation. The sector development and its evolution over the years have been marked by various policies and approaches. These development stages of the...

Commercial rice imports have accounted for approximately 61%, food aid in rice accounted for about 2%, and domestic rice accounted for some 37% per annum of rice consumption in Ghana over the four years between 2000 and 2003. Compared to the 1990s, these figures show a gradual decline in the...

A multi-dimensional, non-linear dynamic model in continuous time is presented for the purpose of finding the optimal combination of exploitation and capital investment in optimal renewable resource management. Non-malleability of capital is incorporated in the model through an asymmetric...

This paper assessed the effects of transactions costs—relative to price and non-price factors—on smallholder marketed surplus and input use in Kenya. A selectivity model was used that accounts not only for the effects of fixed and variable transactions costs but also for the role of assets,...

With the possible exception of nuclear technology, few scientific breakthroughs have generated the level of emotive debate that has surrounded the roll-out of agricultural biotechnology. Initial discussion about the environmental impacts of agricultural genetic modification, are now frequently...

During the last decades the topic of fossil fuel subsidies has been gaining importance in the policy discussion. International Energy Agency (IEA) (2011) estimates that the total global fossil fuel subsidies in 2010 amounted to $409 billion. Kazakhstan is energy-rich country with significantly...

Forest benefits are now commonly understood through the ecosystem service framework. Recreational visits to forests, considered an important cultural service, have been the target of a significant proportion of the non-market valuation literature to date. Such models have evolved from relatively...

Selection logging in the tropics is increasingly moving to systems that reduce the impact of harvesting operations on forests and soils. While much of the focus has been on modifying the tractor logging system using RIL principles, alternative harvesting systems have also been introduced. One of...
