Optimal Design of Permit Markets with an Ex Ante Pollution Target, August 2006

In this paper, we examine the design of permit trading programs when the objective is to minimize the cost of achieving an ex ante pollution target, that is, one that is defined in expectation rather than an ex post deterministic value. We consider two potential sources of uncertainty, the presence of either of which can make our model appropriate: incomplete information on abatement costs and uncertain delivery coefficients. In such a setting, we find three distinct features that depart from the well-established results on permit trading: (1) the regulator’s information on firms’ abatement costs can matter; (2) the optimal permit cap is not necessarily equal to the ex ante pollution target; and (3) the optimal trading ratio is not necessarily equal to the delivery coefficient even when it is known with certainty. Intuitively, since the regulator is only required to meet a pollution target on average, she can set the trading ratio and total permit cap such that there will be more pollution when abatement costs are high and less pollution when abatement costs are low. Information on firms’ abatement costs is important in order for the regulator to induce the optimal alignment between pollution level and abatement costs.

Intra-Industry Trade, Multilateral Trade Integration, and Invasive Species Risk, December 2006

We analyze the linkage between protectionism and invasive species (IS) hazard in the context of two-way trade and multilateral trade integration, two major features of real-world agricultural trade. Multilateral integration includes the joint reduction of tariffs and trade costs among trading partners. Multilateral trade integration is more likely to increase damages from IS than predicted by unilateral trade opening under the classic Heckscher-Ohlin-Samuelson (HOS) framework because domestic production (the base susceptible to damages) is likely to increase with expanding export markets. A country integrating its trade with a partner characterized by relatively higher tariff and trade costs is also more likely to experience increased IS damages via expanded domestic production for the same reason. We illustrate our analytical results with a stylized model of the world wheat market.

Iowa Ag Insider, August 31, 2012

Welcome to the initial edition of the Iowa Ag Insider, the newsletter of the Iowa Department of Agriculture and Land Stewardship. We see this newsletter as a way to keep people informed of the activities of the Department and also highlight some of the exciting things going on in Iowa agriculture in general. If you know of events or stories that should be included in future newsletters I hope that you will share them with us so they can be included in future editions. Also, if you know of people who would enjoy receiving this newsletter I hope you will pass it on as the information on how to subscribe is on the bottom of each issue. This is an exciting time of year in Iowa as farmers and everyone involved in agriculture gets ready to kickoff the growing season. We wish everyone a successful and safe 2013 as we get to the business of growing the crops that help power Iowa’s economy and feed the people of our state and trading partners around the world. Iowa is fortunate to have such a dynamic agriculture industry and each of you play a role in helping make Iowa agriculture so successful.
