The Most-Favored Nation (MFN) clause has long been suspected of creating a free rider problem in multilateral trade negotiations. To address this issue, we model multilateral negotiations as a mechanism design problem with voluntary participation. We show that an optimal mechanism induces only the largest exporters to participate in negotiations over any(More)
Why can some environmental groups successfully compete against polluting industries in influencing government environmental policies? This paper suggests an explanation by developing a model of direct and indirect competition for political influence. Among other things, it is shown that moving to free trade increases the level of polarization in political(More)
Between 1990 and 2008, emissions of the most common air pollutants from U.S. manufacturing fell by 60 percent, even as real U.S. manufacturing output grew substantially. This paper develops a quantitative model to explain how changes in trade, environmental regulation, productivity, and consumer preferences have contributed to these reductions in pollution(More)
This paper reconsiders environmental subsidies in the context where polluting firms procure their abatement goods and services from a specialized oligopoly. To maximize social welfare, the regulator must then simultaneously alleviate two distortions: one that comes from pollution and the other that is due to the environment firms' market power. We find that(More)
A brushless dc motor can be described as an inverted brush dc motor with its magnet being the rotor and its stationary windings forming the stator. This design provides many advantages over the brush dc motor. The operational characteristic of a motor is important for its control, modeling and deriving optimum performance. However, a review of the(More)
Besides radiating sound from the note area being struck, a steelpan radiates from neighboring note areas that vibrate sympathetically, from the areas between notes, and from the skirt [Rossing et al., Phys. Today 49(3), 24-29 (1996)]. Measurements were taken in an anechoic chamber using a four-microphone intensity probe to visualize the acoustic radiation(More)
