This study focused on the interrelationships among producer, auction and world prices. In so doing, it criticized previous studies and extended technique developed by Hansen (1999) to handle inferential biases occurring as a result of specification errors. The following results were found: unidirectional transmission of shocks from the world price to the auction price and then to the producer price; asymmetries in price transmissions and adjustments in the auction market; weak interrelationship between producer and world prices causing producer price to be less responsive to changes in the world prices. In general, results imply that coffee growers’ benefit little from positive changes in the world price compared with participants in the auction markets.... |

This study estimates marginal rates of return to investment in schooling in 12 countries. Significant systematic nonlinearity in the marginal rate of return is found. In particular, the marginal rate of return is increasing significantly at low levels of education, and decreasing significantly at high levels of education. This may help explain why estimates of the return to schooling are often considerably higher when instrumenting for education. |
