Agricultural productivity growth in Chinese provinces during the 1994-2005 period is examined using two alternative approaches: a parametric stochastic frontier and a non-parametric Malmquist index. These models are suitable to the Chinese situation due to the existence of procurement prices, quotas, and other interventions that have distorted prices. Results show that there is high but declining productivity growth rates in the mid 1990’s with productivity growth decreasing in the late 1990’s but with a reversal of the trend around 1998 when growth rates start accelerating. A stochastic frontier translog production function is estimated to obtain an alternative measure of total …

Pricing And Welfare Impacts Of New Crop Traits: The Role Of Iprs And Coase's Conjecture Revisited, Richard K. Perrin, Lilyan E. Fulginiti

Crop traits are durable when embedded in varieties, and thus they may be subject to Coase's conjecture that monopolists who sell durables may be unable to earn normal monopoly rents, or in the extreme case, not any rents at all. To determine the potential relevance of this conjecture for the crop traits market, we analyze the theoretical time path of trait prices under three systems of intellectual property rights (utility patents, plant breeders' rights, and none), alternative assumptions about sellers' ability to commit to future action, and alternative assumptions that buyers are either myopic or far-sighted with respect to expectations …
