Abstract

Food production contributes considerably to global greenhouse gas (GHG) emissions. Animal products – particularly meat from ruminants – generally have higher GHG emissions than plant products. Over the last few decades the global per capita consumption of animal products has increased. This has a negative impact on climate change, land and water availability, and human health. We are faced with the two-fold challenge of reducing GHG emissions while still producing enough food for our growing population. Part of the solution could be for consumers to change towards a more sustainable diet. In this paper we take Norway as a case study for estimating optimal taxes and subsidies on different food items which can change consumption patterns in order to reduce the GHG emissions derived from the average Norwegian diet. In the estimate we ensure that the average calorie intake with the new diet remains the same as with the current diet, and factor in other health considerations. Our findings suggest that limited but useful emission reduction targets can be set with only a few changes in diets. The methodology presented in this paper may be used to estimate optimal climate taxes and subsidies under different emission, quantities, taxes, subsidies, and health constraints.

Abstract

Markets for cash-crops in developing countries are typically characterized by a concentration of buyer power at different levels of the supply chain. For instance, small-scale coffee farmers sell their produce to a middleman, who in turn sells the coffee onward to an exporter, often a foreign multinational, with monopsony power in the hands of the purchasers at both levels. We analyze pricing behavior and welfare with different assumptions regarding market power. In particular, we show that a more powerful exporter is likely to benefit the producers and may even lead to higher welfare for the producer country as a whole.
