Equilibrium Approach (equilibrium + approach)
Selected AbstractsSchool Attendance and Skill Premiums in France and the US: A General Equilibrium Approach,FISCAL STUDIES, Issue 4 2007David De La Croix We evaluate the effect of education policies, welfare programmes, technology and demographics on the differential evolution of the skill premium and on the rise in education investment in France and the US. We use a computable general equilibrium model with overlapping generations of individuals and endogenous education decisions. Human capital has two substitutable components - experience and education - both of which evolve endogenously over time. We use an original method to calibrate our model properly on the post-war period and run counterfactual experiments to assess the relative contributions of the different exogenous variables. The expansionary French education policy boosted the supply of skills and kept the skill premium low. In contrast, increasing education costs in the US contributed to increased wage differentials by reducing the rise in educational attainment. Skill-biased technical change is key to understanding rising school attendance and skill premiums in the US. It has a less important role and appears to be delayed in France.

[source] Japanese Rice Market Liberalization: A Competitive Equilibrium ApproachTHE JAPANESE ECONOMIC REVIEW, Issue 4 2000Hiroshi Fujiki This paper quantifies the effect of Japanese rice imports on the Japanese rice market with special attention to the farmland market in the year 2000, based on information available in 1997. Tariff and quota policies do not affect the equilibrium price of rice and rent significantly, given the current acreage controls. The removal of the acreage control programme would reduce the autarky price of rice by 30%. With free importation of rice into Japan, the price of rice would be halved, and the potential increase in the consumer surplus could be 0.3% of the 1995 Japanese GDP.

[source] Kinetic and Thermodynamic Solubility Values of Some Bioactive CompoundsCHEMISTRY & BIODIVERSITY, Issue 11 2009Elham Shoghi Abstract Thermodynamic solubility is a decisive physicochemical property in drug development. The Chasing Equilibrium method offers an alternative to the classical procedures to measure the solubility of compounds with acid,base properties. The method is fast and yields accurate results. In this work, the solubility of several compounds including acids and bases was determined through the Chasing Equilibrium approach. A study of experimental conditions in terms of sample weight was performed to measure solubilities. The study shows that only a limited range of weights, depending on the nature and solubility of the compounds, is adequate to obtain reliable results. [source] Punctuated Equilibrium and Agenda-Setting: Bringing Parties Back in: Policy Change after the Dutroux Crisis in BelgiumGOVERNANCE, Issue 3 2008STEFAAN WALGRAVE The article analyzes how focusing events affect the public and political agenda and translate into policy change. Empirically, the study focuses on the policy changes initiated by paedophile Marc Dutroux's arrest in 1996 in Belgium. Theoretically, the article tests whether Baumgartner and Jones's (1993) U.S. punctuated equilibrium approach applies to a most different system case, Belgium being a consociational democracy and a partitocracy. Their approach turns out to be useful to explain this "critical case": Policy change happens when "policy images" and "policy venues" shift. Yet, the Dutroux case shows also that political parties, as key actors in the Belgian policy process, should be integrated more explicitly in the punctuated equilibrium theory. Finally, the article argues that the quantitative analysis of longitudinal data sets on several agendas should be supplemented with qualitative case study evidence (e.g., interviews with key decision makers) to unravel the complex case of issue attention and policy change. [source] Study on the action of the active earth pressure by variational limit equilibrium methodINTERNATIONAL JOURNAL FOR NUMERICAL AND ANALYTICAL METHODS IN GEOMECHANICS, Issue 10 2010Li Xinggao Abstract Within the framework of limiting equilibrium approach, the problem of active earth pressure on rigid retaining wall is formulated in terms of the calculus of variations by means of Lagrange multipliers. It is transcribed as the functional of extreme-value problem by two undetermined function arguments, and is further transformed into determining the minimax solution of restrained functions incorporating the geometrical relations of the problem. The function of (fmincon) in the optimization toolbox of MATLAB 6.1 can be used to find the minimax solution. Computation results show there exist two kinds of modes of failure sliding along plane surface and rotating around log-spiral cylinder surface when the soil behind the walls reaches the critical active state. The magnitude of active earth pressure in the case of translational mode is less than that in the case of rotational mode. The location of action point of earth pressure in the case of translational mode is at or below height of the wall, and in the case of rotational mode, is above height of the wall. Preliminary study indicates a pair of numbers by two theoretical modes can be regarded as an interval estimation of active pressure. Copyright © 2009 John Wiley & Sons, Ltd. [source] The urban market for farmers' water rights,IRRIGATION AND DRAINAGE, Issue 4 2003Stephen Merrett stress de répartition; irrigation; droits à l'eau; provision urbaine Abstract Allocation stress, that is, access conflicts between the agricultural, domestic, industrial, urban service and environmental uses of water, is set to become more intense in the future because of global population growth and climate change. Because of the dominant role of irrigation water use at the global level, it is imperative to explore the possibilities of reducing farmers' use of water or, at the very least, of slowing its growth. One process by which the scale of irrigation is reduced occurs when farmers choose to sell their water rights to actors that apply these released flows in towns and cities for household, manufacturing and urban service uses. In this paper a theory of price and volume determination of such markets is presented, using concepts of urban actors' maximum bid price and farmers' minimum release price for water rights. The limits of the theory are then discussed with respect to timescale, water concessions, part-sales, sales of land, the legal context, third-party effects, market structure and transaction costs. The main conclusion is that the market equilibrium approach is rarely applicable and that fieldwork will in general have to deal with arcane, one-off bilateral trades.

Les contraintes d'allocation de l'eau, c'est-a-dire, les conflits d'accès à l'eau entre secteurs agricole, domestique, industriel, urbain et de l'environnment, vont augmenter dans le futur, à cause du changement du climat et de la croissance de la population mondiale. Le rôle dominant de l'irrigation tend de réduire l'usage de l'eau dans la secteur agricole. Cette réduction se produit quand les fermiers vendent leur droits à l'eau aux acteurs urbains. Dans cet article on présente une théorie des prix et quantités de ces marchés. On présente aussi les limites de la théorie et on conclut que l'approche par équilibre du marché s'applique rarement et qu'il faut en pratique considerer egalement des transactions obscures et bilatérals.

[source] Predicting solubility in multiple nonpolar drugs,cyclodextrin systemJOURNAL OF PHARMACEUTICAL SCIENCES, Issue 11 2002Luwei Zhao Abstract This study presents a model to predict the solubility of a nonpolar drug DA in the presence of other nonpolar drugs D1,Dn in a complexing ligand L system such as hydroxypropyl-,-cyclodextrin (HP,CD). Using an equilibrium approach, the model describes the molecular interactions among these drug species and the ligand. The model indicates that the solubility of DA invariably decreases as a result of the presence of D1,Dn. Furthermore, the decrease in DA solubility is related to the sum of the products of the intrinsic solubilities of the other drugs and drug,ligand complexation constants. To test the model, three steroids (prednisolone, 17,-hydroxyprogesterone, and progesterone) were used as model compounds in HP,CD solutions. The experimental data showed that the solubility of any particular drug decreased in the presence of other drugs. At all tested HP,CD concentrations, these experimental solubility data were in good agreement with the predicted solubility data. This result lends strong support to the reliability and effectiveness of the proposed model. © 2002 Wiley-Liss, Inc. and the American Pharmaceutical Association J Pharm Sci 91:2301,2306, 2002 [source] How Does Economic Development in Eastern Europe Affect Austria's Regions?JOURNAL OF REGIONAL SCIENCE, Issue 2 2002A Multiregional General Equilibrium Framework The paper quantifies regional welfare effects arising from the increasing trade flows between Austria and its Eastern neighbors after the opening up of Eastern Europe. We calibrate a static multiregional Computable General Equilibrium (CGE) model with benchmark data from 1994 for Austria, subdivided into nine Federal Provinces. The regions are linked by trade flows with the four Eastern neighboring countries and with the rest of the world. We simulate the effects of the increase of trade interpenetration as observed between 1989 and 1999 in a comparative static analysis. Regional welfare effects under fixed and flexible wages are presented. We also compare national CGE results with estimates obtained in a simple partial equilibrium approach. [source] An Economic Analysis of the Returns to Canadian Swine Research: 1974,97CANADIAN JOURNAL OF AGRICULTURAL ECONOMICS, Issue 2 2001Greg Thomas This paper reports a new set of estimates of the returns to swine research in Canada. These estimates are obtained using Agriculture and Agri-Food Canada's Canadian Regional Agricultural Model (CRAM). Positive Mathematical Programming is incorporated into the model for use in this study. The CRAM allows the effects of supply shifts from technological change in the hog industry to interact with product and factor market conditions in the rest of Canadian agriculture. Extensive sensitivity analysis is conducted to examine the robustness of the return estimates under variations in some of the key assumptions employed in the analysis. The costs of public and private sector swine research are estimated. Public sector research costs are inclusive of the marginal excess burden of taxation. Overall, the estimated benefits from Canadian swine research are high relative to the estimated costs for the time period considered. Previous estimates of the returns to Canadian swine research were obtained by Huot et al. (1989) with a partial equilibrium model that did not allow for intra-sectoral resource use adjustments. The estimated returns obtained in the present study are generally higher than those obtained by Huot et al. For example, the estimates obtained from the direct application of the econometrically estimated supply function in this study gave an internal rate of return of about 124% and a benefit-cost ratio of 22.4 to 1. Huot et al reported comparable estimates of about 43% for the internal rate of return and 6,7 to 1 for the benefit-cost ratio. The differences in returns are not solely attributable to the use of a multi-market versus a single-market partial equilibrium approach. There are also differences in the estimates of the marginal excess burden of taxation between the two studies. L'analyse que void présente une nouvelle série d'estimations quant au rendement de la recherche porcine au Canada. Ces estimations dérivent du Modèle d'analyse régionale de l'agriculture du Canada (MARAC) du ministère canadien de l'Agriculture et de l'Agroalimentaire. Aux fins de la présente étude, on avait intégré au modèle une programmation mathématique positive. Le MARAC autorise l'interaction entre les retombées d'une modification de l'offre attribuable au virage technologique de l'industrie porcine et les conditions du marché des produits et des facteurs dans le reste de l'agriculture canadienne. Les auteurs ont effectué une analyse de sensibilité poussée en vue d'établir la robustesse de leurs estimations quand variaient quelques-unes des principales hypotheses de l'analyse. On a estimé le coût de la recherche sur les pores poursuivie par les secteurs public et privé. Dans le secteur public, le coût de la recherche incluait une charge fiscale légérement excessive. Dans l'ensemble, la recherche sur les porcs entreprise au Canada a rapporté beaucoup comparativement à ce qu'elle a coûté pendant la période à l'étude. Les estimations antérieures, établies par Huot et ses collaborateurs (1989), venaient d'un modèle àéquilibre partiel ne permettant aucun ajustement pour l'utilisation intra-sectorielle des ressources. Les revenus estimés ici sont généralement plus élevés que ceux de Huot et de ses collaborateurs. Ainsi, une application directe de l'offre estimée par des méthodes économétriques à l'analyse donne un taux de rendement interne d'environ 124 % et un indice de rentabilité de 22,4 pour 1. À titre de comparaison, Huot et ses collaborateurs rapportent des résultats d'environ 43 % pour le taux de rendement interne et de 6 à 7 pour 1 en ce qui concerne l'indice de rentabilité. Pareil écart ne résulte pas uniquement du choix d'un modèle àéquilibre partiel reposant sur plusieurs marchés au lieu d'un seul; on relève aussi des variations dans l'estimation du léger excès de la charge fiscale entre les deux études.
