The most-favored nation rule in club enlargement negotiation

We study the effects of the Most-Favored Nation rule in an applicant's negotiation to join a club. When the applicant has to carry out a series of bilateral bargains with the existing members, we find that there are two effects of the MFN rule, viz. the hardened bargainer effect and the free-rider effect. The former effect tends to favor the applicant, while the latter effect tends to hurt the applicant. We find that the free-rider effect is stronger the more asymmetric are the members. The hardened bargainer effect is stronger the larger is the "size of the pie." As the number of members increase, it is more likely that the hardened bargainer effect would dominate.International trade ; Industrial organization (Economic theory) ; World Trade Organization

Would global patent protection be too weak without international coordination?

I extend the Grossman and Lai (2004) model to answer the question, "Would global patent protection be too weak without international coordination?" by introducing firmbiased government preferences and trade barriers in the model. I make use of the estimates of the firm-bias parameter from the political economy literature to proxy for the degree of governments' firm-bias. Then I calculate the range of trade barriers that is sufficient to give rise to under-protection of patents in the global system without international policy coordination in IPR protection. I make the judgement that the true trade barrier between countries very likely falls within this range of under-protection. Therefore, I conclude that there was probably under-protection of patents without international policy coordination in IPR protection. It means that the free-rider problem with a large number of independent players overrides the effects of firm-bias and trade barriers, giving rise to too low a rate of innovation in the world. Allowing for the possibility that countries discriminate against foreign firms in Nash equilibrium does not change this conclusion. The problem can possibly be corrected by international coordination in intellectual property rights (IPR) protection.Intellectual property rights, TRIPS, Innovation

A Quantitative Study of the Effect of Cutting & Fibrillation on Certain Paper Properties

Introduction From the time of the invention of paper about the year 105 by Ts\u27ai Lun, the process of beating the pulp as a preliminary to forming a sheet of paper has been recognized as of prime importance. Early papermakers did not concern themselves greatly with theories; it was enough to know the process necessary to produce the various combinations of long and short, slow and free stocks according to the paper being made. When chemists began to enter the mills, however, their attention was naturally drawn to this important aspect of beating, and to the relationship between cellulose and water in the beating cycle. This relationship is of such fundamental importance in the practice of papermaking that it has been subject to a myriad of published unanimity amongst the so-called experts concerning this complex cellulose-water relationship in beating. In order to explain the various known effects of beating, there seem to be two distinctly different schools of thought to consider; those supporting the chemical aspects of beating, and those advocating the physical colloidal aspects of the beating action

Free-molecule-flow force and moment coefficients of the aeroassist flight experiment vehicle

Calculated results for the aerodynamic coefficients over the range of + or - 90 deg in both pitch and yaw attitude angles for the Aeroassist Flight Experiment (AFE) vehicle in free molecule flow are presented. The AFE body is described by a large number of small flat plate surface elements whose orientations are established in a wind axes coordinate system through the pitch and yaw attitude angles. Lift force, drag force, and three components of aerodynamic moment about a specified point are computed for each element. The elemental forces and moments are integrated over the entire body, and total force and moment coefficients are computed. The coefficients are calculated for the two limiting gas-surface molecular collision conditions, namely, specular and diffuse, which assume zero and full thermal accommodation of the incoming gas molecules with the surface, respectively. The individual contribution of the shear stress and pressure terms are calculated and also presented

MANAGING NUTRIENT LOSSES: SOME EMPIRICAL RESULTS ON THE POTENTIAL WATER QUALITY EFFECTS

Over-application of manure on cropland can cause water quality degradation. This paper reports a modeling approach for assessing tradeoffs among manure storage and handling systems as they relate to the nutrient loadings in cropland runoff, including nitrate losses to groundwater. The CREAMS simulation model provided estimates of nutrient losses. A linear optimization model was used to determine the income-nutrient loss tradeoffs. Six-month storage was profitable for farmers with average-size dairy herds, but compared to daily spreading caused increased nitrate leaching through the soil to groundwater resources. Twelve-month storage systems decreased farm profitability while decreasing the total nitrogen losses from farm fields.Environmental Economics and Policy,
