Treatments of the exchange energy in density-functional theory

Following a recent work [Gal, Phys. Rev. A 64, 062503 (2001)], a simple derivation of the density-functional correction of the Hartree-Fock equations, the Hartree-Fock-Kohn-Sham equations, is presented, completing an integrated view of quantum mechanical theories, in which the Kohn-Sham equations, the Hartree-Fock-Kohn-Sham equations and the ground-state Schrodinger equation formally stem from a common ground: density-functional theory, through its Euler equation for the ground-state density. Along similar lines, the Kohn-Sham formulation of the Hartree-Fock approach is also considered. Further, it is pointed out that the exchange energy of density-functional theory built from the Kohn-Sham orbitals can be given by degree-two homogeneous N-particle density functionals (N=1,2,...), forming a sequence of degree-two homogeneous exchange-energy density functionals, the first element of which is minus the classical Coulomb-repulsion energy functional.Comment: 19 pages; original manuscript from 2001 (v1) revised for publication, with presentation substantially improved, some errors corrected, plus an additional summarizing figure (Appendix B) include

Cultural Barriers and Agricultural Trade in the Western Hemisphere

This study analyzes the impacts of cultural distance on bilateral trade flows in the Western Hemisphere using a Fixed Effects Vector Decomposition (FEVD). Four cultural dimensions of Hofstede are used to capture cultural distance. The results found that the effects of each dimension vary considerably with three of four dimensions (UAI, PDI, and MFI) have a negative impact and one dimension (ICI) has a positive effect. The magnitude of ICI is large enough to offset the negative effects of the other three dimensions resulting in a net positive effect of cultural distance, suggesting that culturally-dissimilar countries trade more than less.agricultural trade, cultural distance, gravity model, International Relations/Trade,

IMPACTS OF GLOBALIZATION ON AGRICULTURAL COMPETITIVENESS: THE CASE OF NAFTA

Major components of agricultural competitiveness, including definitions, factors, and indicators of competitiveness, are discussed, The case of the North American Free Trade Agreement (NAFTA) is used to illustrate how factors have influenced the competitive position of the NAFTA countries. Traditional neoclassical trade theory is used to evaluate the impact of currency exchange rate fluctuations and trade preferences on agricultural competitiveness. Pre- and post-NAFTA market shares are evaluated for five agricultural commodities of importance to the southern United States. The results of these evaluations are compared with theoretical expectations and discussed with special emphasis on implications for future trade negotiations.agricultural competitiveness, exchange rates, international trade, NAFTA, International Relations/Trade, F14, Q17, Q18,

Discussion: Exchange Rates, Energy Policy and Outcomes in Agricultural Markets

These three invited papers examine the role that exchange rates may have in influencing commodity prices, input prices and farm income. The papers arguably represent one of the most important recent attempts to quantify and explain these new linkages. As U.S. and world agriculture moves from a period of high output prices to a period of lower prices, understanding the impact of macroeconomic variables on farm input costs and farm income will become more important. Further, it will be equally important for policy makers to undertake appropriate market interventions in order to have maximum effectiveness should this period of cost-price-squeeze continue to intensify. Each of the papers has something significant to contribute to the understanding and debate of these new linkages between agriculture, the macroeconomic environment, and the energy sector.energy, exchange rates, macropolicy, markets, trade, Agribusiness, Farm Management, Financial Economics, Marketing, Resource /Energy Economics and Policy, F42,
