It has been hypothesized that differentially applied environmental regulations create pollution havens, as firms will make choice of to invest in countries with lax environmental standards. Using a theoretical mould of pest control adoption and an empirical spatial equilibrium pattern we examine one such environmental regulation, a U ban forward 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, subject to the assumptions held, Mexico will not dramatically increase its use of methyl bromide following the ban. Sensitivity analysis to this end is conducted.

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

In new articles on trade and the environment, researchers have focused onward how trade agreements and trade mechanisms affect the environment on either increasing production, shifting production sites, or eliminating production, with many researchers estimating environmental Kuznet crooks (see Dean 1992, Nordstrom and Vaughan 1999 and Copeland and Taylor 2003 for scrutinizes of this literature). In addition, attention has been given to by what means trade instruments, such as a ban onward exports or imports, can be used to achieve a reduction in pollution. Other papers have examined in what way 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 thus in a way that distorts resource allocation and imposes large welfare losse (Sullivan 1994)

Our research examines to what degree differentially applied environmental regulations can impact agricultural trade patterns and production location. We evolve a model to predict and standard whether an agricultural pollution haven force is found with respect to Mexico following the U.S.'s phaseout of methyl bromide. To do this, we incorporate costliness yield, and pest pressure differences suitable to geographic and climatic differences on region or country into the empirical studious mood Dean, Lovely, and Wang (2005) find that production differences befitting 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 order to which the stringency of environmental regulations determines production location. In our gauge the heterogeneity derives not from differential access to technology nevertheless to climatic differences and varying on a levels of pest pressure that be derived in varying demands for infection control. The pest control in question, methyl bromide, exhausts the ozone layer-i.e., it is a global rather than local pollutant. We can examine whether, if regulations are imposed in common country to restrict the use of an environmentally damaging nuisance control, affected growers relocate production to another nation or region with less strict regulations or with les great annoyance pressure. Changes in technology use and cropping patterns as a ensue 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 forward 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) no other than 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 increases Lynch's work, developing a theoretical standard and incorporating more crops and regions into the empirical analysis.

Three possible results of unilateral environmental regulation exist: (i) production shifts to the foreign nation 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 rural parts but the foreign country does not adopt methyl bromide, in such a manner global use decreases, domestic prices increase, foreign production increases, and domestic production decreases; and (iii) production does not shift to a foreign abiding habitation domestic production decreases, and domestic prices increase. subordinate to scenario (i), global use of the chemical increases and large costlinesss are imposed on domestic farmers Under scenarios (ii) and (iii), global use decreases, on the other hand the costs to domestic farmers will vary, with lower domestic preciousnesss under scenario (iii).
