Global Warming Policy and the Pennsylvania Economy: A Computable General Equilibrium Analysis

Most studies of the impacts of global warming policy have been performed at the national level. However, national averages obscure the fact that some regions may be affected much more than others. We formulated a regional computable general equilibrium model to analyze the impact of a carbon tax on the Pennsylvania economy. The model incorporates special features relating to labor mobility, trade and energy substitution for this purpose. Our results indicate significant negative overall impacts on the Pennsylvania economy, primarily because it is a major producer and user of fossil fuels, especially coal, and because it is highly industrialized. Sensitivity analyses on key parameters and model assumptions indicate that our results are robust.     

Modelling Commodity Balances in a Computable General Equilibrium Context

This paper is the second part of a two-part discussion which elaborates the proposition that Stone's concept of commodity technology is the appropriate assumption on which to build in modelling commodity balances. The analysis in the first part was developed from a social accounting representation of commodity balances into a formal statement of the Stone model and the conditions under which it admits an acceptable solution. This second part develops a generalization of Stone's original formulation, in the spirit that the modelling of commodity balances should be approached in a general equilibrium context which recognizes that, in the final analysis, prices and quantities are interdependent.     

Agricultural Trade Liberalization in a Computable General Equilibrium Framework for the Philippines

A bi-regional and multi-market computable general equilibrium model that focuses on the agricultural sector of the Philippines' economy in 1987 is constructed. This paper presents the basic structure of the model and carries out some cost-benefit analyses to assess the impact of alternative trade reform policies on the economy. It is found that various liberalization policies can produce large benefits, but any single policy implemented separately may incur intolerable costs. However, a combination of trade liberalization and currency devaluation, coupled with target income support and income tax reform, can achieve balanced results that are beneficial to the economy without worsening income distribution and food consumption of the poor.     

Competitive Pressure on the Indian Households: A General Equilibrium Approach

How would competitive pressure impact upon the income distribution and the poverty of household groups? We analyse the gains in efficiency and productivity due to competitive pressure, and its distributional effects using a general equilibrium input–output framework. Efficient utilization of the available resources, technical progress and free trade constitute our sources of growth. Welfare would increase under competition, but the income distribution would become more skewed. Rural household groups would stand to lose relative to the urban ones. Urban poverty would be reduced significantly more than rural. In fact, the agricultural worker would even suffer from an increase in poverty. The study shows that competitive pressure has a positive effect on efficiency, productivity and poverty, but an adverse effect on the income distribution in the Indian economy.

Price-endogenized Input–Output Model: A General Equilibrium Analysis of the Production Sector of the Japanese Economy

This paper considers a generalization of the open Leontief model, by endogenizing the input coefficients on the basis of the neoclassical multi-sectoral produc-tion function. The adopted production function is of the two-level CES type, which is quite effective for avoiding the multi-collinearity problem. As a result, the estimates obtained are quite stable, satisfying the quasi-concavity conditions of the production function for all the sectors. Comparative statics based on the Jacobian of the excess supply function for each commodity market reveal that, owing to the factor substitution the effect of an increase in the final demand on the level of the production is significantly smaller than that which occurs in the open Leontief model with fixed input coefficients.

Onward the Spatial: an Essay on the Nature and Relevance of Regional Economics

Abstract

Regional economics appears to be losing its currency in academic discourse, with a clear preference over recent years for the term ‘spatial economics’. This essay examines the nature of the developments in order to explore their implications for regional economics, focusing on four key aspects: empirical methods and the ‘tools’ of regional economics; theory and the appropriate spatial scale; the ‘regional problem’; and regional policy. It finds reasons to suggest that the ‘region’ is of less importance, but argues that the use of the term ‘spatial’ does not reflect dissatisfaction with regional economics, but rather it signals the reinvigoration of the subject from its formal connection to mainstream economics. This is primarily in the form of the new economic geography model, although limitations with this have led to an unsatisfactory form of regional policy that is based on growth theory.

Avance de l’économie spatiale: une communication sur la nature et la pertinence de l’économie régionale

RÉSUMÉ L’économie régionale semble avoir perdu du terrain dans les discussions académiques, et on lui préfère clairement, depuis quelques années, l'expression ‘économie spatiale’. La présente communication se penche sur la nature des développements, afin d'explorer leurs implications pour l’économie régionale, en examinant les quatre aspects principaux suivants: les méthodes empiriques et les ‘outils’ de l’économie régionale; la théorie et l’échelle spatiale appropriée; le ‘problème régional’; et la politique régionale. Il détermine des raisons pour affirmer que la ‘région’ joue un rôle moins important, mais estime que l'usage du mot ‘spatial’ ne reflète pas le mécontentement avec l’économie régionale, mais indique un renouveau pour ce sujet après ses liens officiels avec l’économie générale. Ce renouveau se présente principalement sous forme du nouveau modèle de géographie économique, bien que certaines de ses limitations risquent de donner lieu à une forme peu satisfaisante de politique régionale, basée sur la théorie de la croissance.

Avance de lo espacial: un trabajo sobre la naturaleza y la importancia de la economía regional

RÉSUMÉN?La economía regional parece estar perdiendo su difusión dentro de la disertación académica, mientras que durante los últimos años se observa una preferencia clara por el término ‘economía espacial’. Este trabajo examina la naturaleza de los desarrollos con objeto de explorar sus implicaciones para la economía regional, centrándose en cuatro aspectos clave: métodos empíricos y las ‘herramientas’ de la economía regional; teoría y la escala espacial apropiada; el ‘problema regional’; y política regional. Encuentra razones que sugieren que la ‘región’ tiene menor importancia, aunque arguye que el uso del término ‘espacial’ no refleja insatisfacción con la economía regional, sino que indica la revitalización del tema con respecto a su conexión formal con la economía dominante. Esto se da principalmente en la forma del nuevo modelo de geografía económica, aunque sus limitaciones pueden resultar en una forma insatisfactoria de política regional basada en teoría de crecimiento.

A Political Economy Approach to the Neoclassical Gradualist Model of Transition

Abstract.  A political economy approach to the neoclassical gradualist model of transition requires the exposition of what I define the primary elements of the model, which are economic analysis, definition of a good society, speed, political structure, ideological structure and whether the initial conditions were incorporated in the model. After the identification of the primary elements of the neoclassical gradualist model the next step is to identify secondary elements, the desired changes with respect to price liberalization-stabilization, privatization, institutional structure, monetary policy and the financial system, fiscal policy, international trade and foreign aid and social policy. The analytical framework developed makes possible to understand the neoclassical gradualist model from a new and more enlightening perspective. We are better able to comprehend the complexities involved and the disagreements about the reform process. The adoption of a gradual process of transition did not only involve specifying the required policies of a successful transition but also entailed a process, a sequence by which the reforms should be introduced. As such, a process of transition consistent with the policies recommended by the neoclassical gradualists economists is developed. The conclusion reveals the inconsistencies in the model.

A CGE Approach to Measuring the Sectoral Contribution to an Economy: An Application to Western Australian Agriculture

Typically, sectoral contribution to an economy is estimated by measures such as shares in gross domestic/regional product, employment and exports. According to these measures, agriculture's contribution declines as the economy grows. However, the indirect contribution of the sector is likely to rise due to the expansion of agriculture–based processing activities in the process of economic growth. Input–output multiplier analysis is often used to capture such flow–on contributions of the sector. This paper proposes to use a computable general equilibrium framework to estimate the direct as well as indirect contributions of agricultural growth in an economy. It also develops a methodology to distinguish the broader effects of agricultural output growth by source — input growth and productivity growth. The proposed methodologies are illustrated by applying these to analyze the contribution of agriculture to the economy of Western Australia, an agriculture and resources based state of Australia. The results for Western Australia suggest that the indirect benefits of agriculture exceed its direct contributions and that the contributions made by enhancing productivity in agriculture are indeed substantial. Importantly, the broader contribution of the agriculture sector depends critically on the specific source of the sectoral growth — input or productivity growth.     

基于“新都市主义”的混合社区:城市郊区化的一个新思路

在中国诸多大中城市郊区化进程中,一个非常显著的现象是:高档和低档住宅的二元分立,从而破坏了人们居住空间的复合性及和谐性.造成这一现象的根本原因并非人们的"阶层"意识,而是城市郊区化的潜在思路:仅仅关照人们的居住,却没有关照人们的生活,人们的完整生活在郊区化过程中被割裂了.解决这一问题的出路是构建混合式社区,而其理论基础是新都市主义.

A Principal-agent Theory of the Public Economy and Its Applications to China

This paper is intended to model the principal-agent relationship and its associated monitoring-incentive problems of the public economy. The basic findings are: (1) the degree of publicness and the size of the public economy matter: the monitoring effort of the original principals and the work effort of the ultimate agents decrease with the degree of publicness and the size of the public economy; (2) a corrupt public economy can be a Pareto-improvement over the non-corrupt public economy. The first finding sheds some light upon performance comparison between different public economies (such as between Singapore and China). The second finding explains why all socialist economies are corrupt ones. The paper applies the above results particularly to the Chinese economy. This revised version was published online in July 2006 with corrections to the Cover Date.
