The application of Engel’s Curve in a single-product perspective may dramatically change the role of quality in affecting the dynamics of economic performance. This paper introduces a specification of preferences that regards quality as luxury, and quantity as necessary. The analysis is carried out by using a framework similar to Grossman’s and Helpman ’s (1991), while quality is defined as in Stokey (1988). The resulting consumer’s demand crucially depends on quality. Quality is potentially able to prevent the process, implied by neoclassical models, that leads the value of consumption goods to decline over time. By doing so, quality also affects the consumption bundle shares and the variety-specific consumption growth rates, thus influencing all dynamic quantitative variables of the economy. I thank Professor Beniamino Moro for his guidance and encouragement. I thank Stephen Wright for his comments and suggestions. I have benefited from the support of Alessio Moro, Dario Unali, Debora Fletcher, Emilio Merella, Esteban Jaimovich, Francesca Lamanna, Matteo Bellinzas, Mauro Merella and all my friends. I am also indebted to Professor Cuong Le Van and Professor Stephen Parente for their advice. I thank two anonymous Referees for their useful remarks.  相似文献

技术性贸易措施虽然对出口国有显著负面影响,但同时也会迫使出口企业投资研发,产生被动创新效应。当创新的预期收益大于创新研发的一次性投入时,出口企业就会以研发投资的创新来应对国外技术性贸易措施。进口国技术性贸易措施越不苛刻,同时出口企业初始产品质量越好,出口企业定价能力越强,出口企业越倾向于选择被动性创新投资策略。  相似文献
