The impact of moods generated by television programs on responses to advertising

The impact of television-program-generated moods on the processing of embedded advertisements was examined within an experimental setting. Results show that program-induced moods affected the amount of message recall and cognitive responses toward the advertisement. In addition, the results show that the affective bias in the cognitive responses toward the advertisement is affected by program-induced moods. The implications of the results and directions for a program of research are discussed.     

The different roles of product originality and usefulness in generating word-of-mouth

This paper explores how the dimensions of new products, specifically, the originality and usefulness of the products, influence word-of-mouth (WOM). In four studies, using lab and field setups, we find that originality and usefulness have different effects on WOM. We show that consumers spread more WOM about original products, but the valence of what they say depends on the usefulness of the product. Therefore, originality enhances the effect of usefulness such that consumers spread relatively more and more positively valenced WOM about original and useful products compared to less original but equally useful products. Conversely, consumers spread more and more negatively valenced WOM about original products that are not useful compared to less original products with the same level of low usefulness. The results indicate that product originality should be managed carefully when developing and positioning new products. Although originality increases buzz, it might lead to negatively valenced WOM when the usefulness of the product is perceived to be low.     

TRADE,DEBT, AND UNEVEN DEVELOPMENT IN A NORTH-SOUTH MODEL

This paper examines a simple model of North-South trade and capital flows along structuralist lines. The South can choose its growth rate, but must finance its growth in excess of its savings by borrowing from the North. The long-run consequences of this process for the process of uneven development and for Southern debt-dependence are explored. The appropriate responses to a debt crisis are considered.     

Music,music videos,and wear out

Repeated exposure to a music video was found to forestall wear out relative to repetitive exposure to the music only. Susceptibility to wear out in the case of the music video was further reduced by eliminating the closure associated with the story told by the video. The level of positive cognitive responses was posited as a mediator to help explain the observed results. © 1993 John Wiley & Sons, Inc.     

Monetary equilibrium in an overlapping generations model with productive capital

Summary We study perfect foresight competitive equilibrium in an overlapping generations model with productive capital and a fixed nominal stock of money. We obtain almost-complete characterizations of (a) the existence of a monetary equilibrium from an arbitrary initial capital stock, and (b) the existence of anefficient monetary equilibrium from an arbitrary initial capital stock. When the initial capital stock is no larger than the golden rule stock, the necessary and sufficient condition for both (a) and (b) is the dynamic inefficiency (in the sense of Malinvaud) of the autarkic (or nonmonetary) equilibrium from the same initial stock. However, this condition, though necessary, isnot sufficient for the existence of a monetary equilibrium when the initial stock exceeds the golden rule stock (and still more conditions are needed for anefficient monetary equilibrium to exist). We provide characterizations for these cases, and as corollaries obtain examples in which (a) the nonmonetary equilibrium is inefficient but no monetary equilibrium exists, and (b) monetary equilibria exist but no efficient monetary equilibrium does.We are grateful to a co-editor and an anonymous referee for comments that greatly improved the exposition in the paper.     

Vertical trading and uneven development

The phenomenon of vertical trading, in which the center exports a good involving a high degree of processing which leads to economy-wide learning and the periphery exports a good which does not generate such effects, is formalized in a simple dynamic model of trade. It is shown that the periphery can ‘lose’ from such trade relations. Conditions under which this can occur are shown to involve parameters of the learning functions, and the ‘sizes’ of the two countries.     

The service sector and economic growth: some cross-section evidence

It has often been claimed that a relative expansion of the service sector has a deleterious effect on economic growth. This paper uses cross-section country-level data from three decades –1960s, 1970s and 1980s – to see whether in fact this negative relation is reflected in the data. It is found that the effect is negative or positive depending on how the role of the service sector is measured, but there is a strong case that effect is in fact usually negative.     

增长与分配的非正统模型: 对公司高管与金融资本家的分析

有关收入分配与经济增长的非正统模型一般只考虑工人与资本家这两个阶级,但是近期围绕不平等问题的讨论开始关注由工资不平等和高收入人群财富增加所带来的收入分配变化。为了分析这些因素,本文建立了两个分别遵循古典—马克思主义和后凯恩斯—卡莱斯基主义的简单模型,讨论存在这样两类人时——一类是拥有资本的生产工人,另一类是公司高管、金融资本家和传统意义上的资本家——的收入分配的变化由哪些因素决定,又会对经济增长产生什么影响。
