The linkage between macroeconomic policies and agricultural commodity trade has become an important research issue of agricultural economists. This paper investigates the macroeconomic linkage of soybean trade competition between the exporting countries of the United States, Brazil, and Argentina in the EC-12 and Japan import markets. It is argued that U.S. monetary growth may have important impacts on the competitive position of U.S. soybean exports through exchange rates. Two relationships are investigated: (a) the effects of U.S. monetary growth on the agricultural trade weighted exchange rates, and (b) the responsiveness of agricultural commodity prices and U.S. exports to exchange rate movements. Results indicate that a weak dollar increases imports of soybeans and soymeal significantly which serves to increase the equilibrium world price and increase both U.S. and Brazil/Argentina exports in the long run. However, during periods of more expansionary U.S. monetary policy there is little evidence of significant increases in market share position for U.S. soybeans and soymeal in world markets. 相似文献

Summary. This paper defines and studies optimality in a dynamic stochastic economy with finitely lived agents, and investigates the
optimality properties of an equilibrium with or without sequentially complete markets. Various Pareto optimality concepts
are considered, including interim and ex ante optimality. We show that, at an equilibrium with a productive asset (land) and sequentially complete markets, the intervention
of a government may be justified, but only to improve risk sharing between generations. If markets are incomplete, constrained
interim optimality is investigated in two-period lived OLG economies. We extend the optimality properties of an equilibrium with
land and give conditions under which introducing a pay-as-you-go system at an equilibrium would not lead to any Pareto improvement.

At present, our society and its social security system are not prepared to cope with the challenges resulting from the continuous increase of life expectancy. The traditional concept of disease has to be modified for serving the special needs of the elderly. The optimistic compression of disease theory is an intriguing model, but lacks prove by available data. The anti-aging boom diverts the focus from the social and financial burden that will be unevitably caused by long-term care in the future. If there will not be an — up to now unforeseeable — breakthrough in research, particularly dementia will have an enormous impact on social cost which is often underestimated. 相似文献

We study possible rankings of opportunity profiles. An opportunity profile is a list of opportunity sets, one for each agent
in the society. We compare profiles on the basis of the notion of “equality of opportunities”. Our main results show the necessary
and sufficient conditions for this comparison to be made using exclusively the information provided by two cardinal measures:
the number of common alternatives in all sets of a given profile and the difference between the number of alternatives in
the individual sets. We also show that, under additional axioms, we can combine these criteria only in a weighted procedure
or in some lexicographic refinements of a weighted procedure.
