Effect of a Differentially Applied Environmental Regulation on Agricultural Trade Patterns and Production Location: The Case of Methyl Bromide

It has been hypothesized that differentially applied environmental regulations create pollution havens, as firms will elect to invest in countries with lax environmental standards. Using a theoretical original of pest control adoption and an empirical spatial equilibrium protoplast we examine one such environmental regulation, a U ban upon methyl bromide, to determine if an agricultural pollution haven will be created in Mexico. Alterations in agricultural production location, trade patterns, and methyl bromide use are determined. We find that, beneath the assumptions held, Mexico will not dramatically increase its use of methyl bromide following the ban. Sensitivity analysis to this rise is conducted.

The ongoing debate surrounding greatest in quantity multilateral trade agreements revolves around the potential for conflict between environmental protection and trade liberalization. Environmentalists diocese trade liberalization and trade agreements as leading to les stringent environmental standards and more difficulty in achieving novel environmental regulations, as domestic farmers will demand a level playing field. Proponent of trade liberalization, upon the other hand, claim that policies to save the environment are disguised trade barriers.

In novel articles on trade and the environment, researchers have focused upon how trade agreements and trade mechanisms affect the environment by the agency of either increasing production, shifting production sites, or eliminating production, with many researchers estimating environmental Kuznet bend s (see Dean 1992, Nordstrom and Vaughan 1999 and Copeland and Taylor 2003 for observes of this literature). In addition, attention has been given to in what way trade instruments, such as a ban upon exports or imports, can be used to achieve a reduction in pollution. Other papers have examined by what mode environmental regulations affect trade patterns and firm locations (see Dean 1992 Nordstrom and Vaughan 1999 Copeland and Taylor 2003) Several authors have investigated whether trade liberalization is creating pollution havens or a "race to the bottom," where countries lower (or do not raise) their environmental regulations to attract foreign direct investment. Environmental regulations may or may not achieve their intended goal, or may do with equal reason in a way that distorts resource allocation and imposes large welfare losse (Sullivan 1994)

Our research examines in what way differentially applied environmental regulations can impact agricultural trade patterns and production location. We disentangle a model to predict and ordeal whether an agricultural pollution haven issue is found with respect to Mexico following the U.S.'s phaseout of methyl bromide. To do this, we incorporate take away from yield, and pest pressure differences to be paid to geographic and climatic differences through region or country into the empirical investigation Dean, Lovely, and Wang (2005) find that production differences to be paid to different levels of access to technology may affect the impact of the environmental regulations-for example, identical regulations may impact les technologically advanced countries' investment more. Thus, heterogeneity beyond regulatory differences can have important implications in the step to which the stringency of environmental regulations determines production location. In our archetype the heterogeneity derives not from differential access to technology on the other hand to climatic differences and varying horizontals of pest pressure that issue in varying demands for infectious disease control. The pest control in question, methyl bromide, emptys the ozone layer-i.e., it is a global rather than local pollutant. We can examine whether, if regulations are imposed in individual country to restrict the use of an environmentally damaging pestilence control, affected growers relocate production to another geographical division or region with less strict regulations or with les infectious disease pressure. Changes in technology use and cropping patterns as a be the effect of a unilateral (i.e., single region's) change in an environmental regulation are examined.

While previous studies have examined the impact of a unilateral ban upon methyl bromide (USDA 1993, Ferguson and Padula 1994 Sunding et al. 1993 Yarkin et al. 1994 Deepak, Spreen and VanSickle 1994 Deepak, Spreen and VanSickle 1996 Lynch 1996 Carpenter, Gianessi, and Lynch 2000) alone Lynch (1996) included the possibility that Mexican growers would increase their use of methyl bromide following the ban's implementation and thereby dilute the environmental objective of the policy. This research reach outs Lynch's work, developing a theoretical original and incorporating more crops and regions into the empirical analysis.

Three possible results of unilateral environmental regulation exist: (i) production shifts to the foreign political division without regulation, increasing global use of methyl bromide use; domestic prices increase; foreign production increases; and domestic production decreases; (ii) production shifts to the foreign political division but the foreign country does not adopt methyl bromide, in like manner global use decreases, domestic prices increase, foreign production increases, and domestic production decreases; and (iii) production does not shift to a foreign geographical division domestic production decreases, and domestic prices increase. below scenario (i), global use of the chemical increases and large take away froms are imposed on domestic farmers Under scenarios (ii) and (iii), global use decreases, on the contrary the costs to domestic husbandmans will vary, with lower domestic require to be paid [i]or[/i] undergones under scenario (iii).
