Since many countries already pursue a range of environmental objectives for agriculture, in particular the supply of positive externalities or public goods (e.g., wildlife habitat, water supply management, provision of landscape amenities) as well as the reduction of negative externalities, such...

Acreage functions for wheat, incorporating variables that reflect the value of voluntary acreage diversion programs to producers, are estimated fro 1962-76. The elasticities of response to such programs are generally low in comparison to those for market price, indicating that the reduction of...

Date on ten U.S. field crops for the period 1950 to 1977 are used to determine whether alternative single variable measures provide the same assessment of relative variability. The results demonstrate that the measurement and analysis of instability may be highly dependent on the choice of...

Estimates are presented of potential variability in real world price and its source. The estimated variance of potential deviations from trend has roughly doubled since 1960/61. The bulk of this variability is attributable to the effects of fluctuations in domestic production in LDC and CPC...

The paper examines the issues involved in reaching a workable international agreement on reserve stocks for wheat. The paper is divided into two parts. In the first part, there is an examination of past efforts to achieve greater food security through international wheat agreements and food aid...

The relative decline in wheat consumption in the developed countries is reducing the potential stabilizing effect on the world market of freer trade in these countries. Furthermore, the growing role of centrally planned countries as importers is increasing the potential instability in world...
