Welfare impacts of alternative biofuel and energy policies AgEcon
Cui, Jingbo; Lapan, Harvey E.; Moschini, GianCarlo; Cooper, Joseph C..
We employ an open economy general equilibrium model to investigate the effects of government energy policy, with emphasis on corn-based ethanol, on the U.S. economy. The model specification incorporates world and domestic markets, assumes pollution costs from fuel consumption, and allows endogenous determination of equilibrium quantities and prices for oil, corn and ethanol. The model is calibrated to represent a recent benchmark data set for 2009 and is used to simulate the positive and normative effects of alternative policies. We find that a second best policy of a fuel tax and ethanol subsidy approximates fairly closely the welfare gains associated with the first best policy (optimal carbon tax and tariffs on traded goods).The largest economic gains to...

A területhasználat változásai AgEcon
Farkas, Jeno Zsolt; Csatari, Balint.
A mezőgazdasági termelést meghatározó tényezők – környezeti, gazdasági, tár¬sadalmi és politikai szempontból – jelentősen változtak az elmúlt öt évtizedben. Földrajzi elemzésünk eredményeként látható, hogy napjainkban átmeneti időszakban vagyunk, melyet jól definiálható trendek, a mezőgazdasági területek csökkenése és az élelmiszerek iránti kereslet növekedése határoznak meg, ezért hazánkban fontos feladat, hogy e körülmények között a KAP 2014 utáni reformjára felkészüljenek. Fontos, hogy olyan támogatási rendszer érvényesüljön, amely a környezetre ható és a területhasználatban jelentkező negatív folyamatokat új pályára állítja, vagyis fenntartható legyen. Magyarország területhasználati változásairól megállapítható, hogy az Európai Unió országaihoz hasonló...

Impact of the EU Biofuels Directive on the EU food supply chain AgEcon
Tabeau, Andrzej A.; Banse, Martin; Woltjer, Geert B.; van Meijl, Hans.
The paper investigates the impact of the EU Biofuels Directive (BFD) on the EU agri-food supply chain using the computable general equilibrium model of the world economy named LEITAP. LEITAP is an extended version of the Global Trade Analysis Project (GTAP) model including an improved land market modeling, substitution possibilities between capital and energy as well as between different energy sources including biofuels, feed byproducts of the biofuel production process and substitution between different feed components and feed byproducts. The simulation results shows that the implementation of the EU BFD has a pronounced impact on the markets of cereals, oilseeds and sugar and shows only a limited impact on production and consumption of other agrifood...

THE 1996 FAIR ACT: MEASURING THE IMPACTS ON LAND LEASING AgEcon
Parsch, Lucas D.; Bierlen, Ralph W.; Ahrendsen, Bruce L.; Dixon, Bruce L..
Major innovations of the 1996 FAIR Act are PFC payments and almost complete planting flexibility. Because payments are attached to the land and not production, landlords are thought to capture most of the PFC payments. With the use of a November 1997 operator survey of cropland leasing arrangements in the Mississippi Delta of Arkansas, the current study investigates changes in crop mixes on leased land, operator attitudes concerning the operator/landlord sharing of FAIR Act benefits, and changes in leasing arrangements as a results of the FAIR Act. Although a number of operators agree that landlords disproportionately benefit from the FAIR Act, about three-quarters felt that there was not change or had no opinion. Similarly, we find little evidence...
