Extending General Equilibrium to the Tariff Line: U.S. Dairy in the DOHA Development Agenda
Market access has been at the core of eight negotiating rounds of the General Agreement on Tariffs and Trade (GATT). Yet, agricultural trade remains a heavily protected sector, characterized by higher tariffs relative to industrial goods, large tariff dispersions, numerous specific tariffs and systems of tariff-rate-quotas. This has made the analysis of trade liberalization a formidable task among policy analysts. Previous studies of agricultural trade liberalization have used partial or general equilibrium models of trade. However, each of these modeling strategies has their drawbacks. General equilibrium (GE) models have been criticized because they face serious aggregation issues and miss much of the policy detail that occurs at the tariff line. Partial equilibrium (PE) models on the other hand are often more disaggregated but lack internal consistency and have nothing to say about the economy-wide effects from trade reform. The purpose of this paper is threefold. One, we develop a methodology that combines PE and GE modeling techniques permitting us to extend GE to the tariff line. Two, we introduce a fully disaggregated U.S. dairy sector and compare PE and GE liberalization results from global dairy reform, thereby offering some insight into the potential errors implicit in current GE studies. Finally, we illustrate how our methodology allows for an explicit treatment of tariff rate quotas in the U.S. dairy sector on a bilateral basis for narrowly defined product lines.agricultural trade, mixed-complementarity problem, partial equilibrium, general equilibrium, Doha Development Agenda, WTO, International Relations/Trade, Livestock Production/Industries, F01, F17, Q17, Q18,
Electronic Structure and Scaling of Coulomb Defects in Carbon Nanotubes from Modified H\"uckel Calculations
Controlled doping and understanding its underlying microscopic mechanisms is
crucial for advancement of nanoscale electronic technologies, especially in
semiconducting single-wall carbon nanotubes (s-SWNTs), where adsorbed
counterions are known to govern redox-doping levels. However, modeling the
associated 'Coulomb defects' is challenging due to the need for large-scale
simulations at low doping levels. Using modified H\"uckel calculations on 120
nm long s-SWNTs with adsorbed ions, we study the scaling properties
of shallow Coulomb defect states at the valence band edge and quantum well (QW)
states in the conduction band. Interestingly, the QW states may underlie
observed exciton band shifts of inhomogeneously doped semiconductors. Binding
energies of Coulomb defects are found to scale with counterion distance,
effective band mass, relative permittivity and counterion charge according to
, with as
an empirical parameter, deepening our understanding of s-SWNT doping
Global Implications of U.S. Biofuels Policies in an Integrated Partial and General Equilibrium Framework
With the increasing research interests in biofuels, global implications of biofuels production have been generally examined either in a partial equilibrium (PE) or general equilibrium (GE) frameworks. Though both of these approaches have unique strengths, they also suffer from many limitations due to complexity of addressing all the relevant aspects of biofuels. In this paper we have exploited the strengths of both PE and GE approaches for analyzing the economic and environmental implications of the U.S. policies on corn-ethanol and biodiesel production. In this study, we utilize the Forest and Agricultural Sector Optimization Model (FASOMGHG: Adams et al. 1996, 2005; Beach et al. 2009), a non-linear programming, PE model for the United States. We also use the GTAP-BIO model (Birur et al. 2008), a multi-region, multi-sector CGE model for global-scale assessment of biofuels policies. Following Britz and Hertel (2009), we link the GTAP-BIO model through a static, quadratic restricted revenue function obtained from perturbing crop prices from the FASOMGHG model. With this linkage we implement the U.S. Corn ethanol and biodiesel scenarios in the GTAP-BIO model and obtain the FASOMGHG-consistent, global land use changes. The resulting crop price changes from the GE model are fed back into the FASOMGHG model to obtain the disaggregated impacts in the U.S.Biofuels, Indirect land use change, Land use emissions, Partial Equilibrium, Computable General Equilibrium, Land Economics/Use, Resource /Energy Economics and Policy,
Recreational Use of State Forests in Mid-America
In the early years between 1920 and 1935, state forest land was not a consideration for recreational use. But since the 1930\u27s, increased attention has been brought to the role of state forests and state parks in providing outdoor recreational opportunities
Collisionless energy absorption in the short-pulse intense laser-cluster interaction
In a previous Letter [Phys. Rev. Lett. 96, 123401 (2006)] we have shown by
means of three-dimensional particle-in-cell simulations and a simple
rigid-sphere model that nonlinear resonance absorption is the dominant
collisionless absorption mechanism in the intense, short-pulse laser cluster
interaction. In this paper we present a more detailed account of the matter. In
particular we show that the absorption efficiency is almost independent of the
laser polarization. In the rigid-sphere model, the absorbed energy increases by
many orders of magnitude at a certain threshold laser intensity. The
particle-in-cell results display maximum fractional absorption around the same
intensity. We calculate the threshold intensity and show that it is
underestimated by the common over-barrier ionization estimate.Comment: 12 pages, 13 figures, RevTeX
Constructive Memory for Bizarre and Sensible Sentences
Sensible, interrelated sentences were presented with or without bizarre sentences that could be transformed to fit the context of the sensible sentences. Two experiments examined subjects\u27 ability to recognize or recall both types of sentences, either immediately or after 2 weeks. Bizarre sentences were frequently recognized at immediate testing; they were generally unavailable at delayed recognition and were never recalled verbatim. In addition, results indicated that transformations of bizarre sentences were stored in memory but were not well incorporated within the structure for the sensible material. These findings are consistent with a constructive approach to memory. Finally, the results suggest that processing bizarre information can lead to more accurate recognition and recall of the sensible context

Cognition, Emotion, and Memory: Some Applications and Issues
This chapter describes some ways in which the psychology of cognition, emotion, and memory can or might be applied in several practical settings. Recent years have seen a rapid growth in research on cognition and emotion and this research has been summarized in a variety of sources (e.g., Ellis & Ashbrook, 1988, 1989; Ellis, Varner, & Becker, in press; Fiedler & Forgas, 1988; lsen, 1984; Kuiken, 1989; Williams, Watts, MacLeod, & Mathews, 1988). Moreover, a new journal appeared in 1987, Cognition and Emotion, which is entirely devoted to relations among emotional states and the full range of cognitive processes typically studied by psychologists. Ellis and Ashbrook (1989) noted that although this research area has a much earlier history of activity, it lay relatively dormant until the mid-1970s. However, its growth has accelerated rapidly until it has now become an important and active area of research and theoretical development
