Volatility in the knowledge economy

Summary. We seek to explain the economic volatility of the last 6 years, in particular the rapid expansion and contraction of the knowledge sectors. Our hypothesis is that these sectors amplify the business cycle due to their increasing returns to scale, growing faster than others in an upswing and contracting faster in a downswing. To test this hypothesis we postulate a general equilibrium model with two sectors: one with increasing returns that are external to the firm and endogenously determined - the knowledge sector - and the other with constant returns to scale. We introduce a new measure of volatility of output, a real beta, and derive a resolving equation, from which we prove that the increasing return sectors exhibit more volatility then other sectors. We validate the main results on US macro economic data of real GDP by industry (2-3 digits SIC codes) of the 1977-2001 period, and provide policy conclusions.Received: 18 March 2002, Revised: 16 February 2004, JEL Classification Numbers: D5, D58, E10, L50, L52, O38, O51.Correspondence to: Graciela Chichilnisky     

Anticipated Environmental Policy and Transitional Dynamics in an Endogenous Growth Model

This paper makes a new attempt toinvestigate how an anticipatedenvironmental policy governs the transitionaldynamics of an economy when pollutionexternality is taken into account. Themodeling strategy we use is an AK technologyendogenous growth framework with an endogenousleisure-labor choice. It is found that, unlikeinelastic labor supply framework, a rise inpublic abatement expenditure will stimulate thebalanced economic growth rate. It is alsofound that public abatement technology plays animportant role in determining the transitionaladjustment of the economic growth rate inresponse to a pre-announced environmentalpolicy.     

阴山北麓农牧交错带观光农业资源优势与开发构想--以武川为例

随着经济的发展,在人们生活条件改善和物质水平提高的同时,城乡居民对高质量的生存环境和丰富的业余生活提出了强烈要求,观光农业作为一种全新的旅游方式受到了人们的青睐。内蒙古武川县属阴山北麓农牧交错带,县境内以缓坡丘陵为主,结合当地的带状种植,形成优美的田园风光,且地理条件优越,具有很大的旅游潜力。本文从武川县发展观光农业旅游的意义、区位、资源及政府扶持等优势出发,分析了在武川县建立观光农业园区的可行性,并提出建立田园景观观光区、采摘区、高新技术农业园区和人文历史名胜旅游区的开发构想和建议。     

影响我国农民市场主体地位确立的制度因素

拥有自主产权是农民成为真正市场主体的必要条件,包括诸如组织制度、户籍制度、金融制度、社会保障制度等在内的产权支持系统是影响农民成为市场主体的充分条件。市场主体地位的高低在某种意义上是由经济实体在参与市场经济活动时所拥有的权利束决定的。推进农村经济市场化的过程就是加强农民市场主体地位的过程。进一步深化农村体制改革,从根本上消除不合理制度对农民的束缚,使农民成为真正的市场主体是解决当前“三农”问题的根本出路。     

Assessing the impact of patent infringement on new product sales

In order to assess the impact of patent infringement on the growth of a new product, a model is developed through the intervention model development processes of Box-Jenkins and Box-Tiao. Physical interpretations of model parameters and determination of associated damages suggest that the model can provide a sound basis for analyzing patent infringement disputes.     

新古典生产函数的质疑与货币量值的生产函数

新古典理论以生产函数和效用函数为基础,建立了技术关系的稀缺资源有效配置理论,其核心是表明商品和要素稀缺性的相对价格.生产函数在微观尚可应用,但并不能用于解释总量经济和经济增长与波动问题.尤其是总供给完全取决于实物生产函数的投入产出关系,这与总需求分析所采用的货币支出是不协调的.货币量值的生产函数的推导表明,总供给只是企业的货币成本函数而不联系到技术上的投入产出关系,而所有的国民收入核算中的货币量值都只是表明人们经济关系的名义变量而与实物的技术关系或生产函数是完全无关的.
