Apparel preferences of pregnant employed women

Women who have postponed childbirth to become established in a career are now embarking on parenthood while continuing to work throughout much of the pregnancy. As a result, pregnant employed women need clothing that will project an appropriate image. The purpose of this research was to determine the types of garments that pregnant employed women prefer to wear to work and to identify factors influencing the selection of those garments. Results indicated that there were differences among age range groups in selection of workplace attire, and among educational level groups in general fashion appeal of classically styled garments, selection of attire for the workplace, selection of nylon for the summer season, and in care required for garments. There were differences among income range groups in the classic category of general fashion appeal, in the selection of silk fibre for winter wear, and in care required for garments. This study supported the concept of a new and separate segment of the consumer market dealing with pregnant employed women. They have special needs for attire based on age range, educational level, and income range, that will project an appropriate image in the workplace and offer physical and psychological comfort as well.     

Earnings Metrics,Information Processing,and Price Efficiency in Laboratory Markets

An enduring issue in financial reporting is whether and how salient summary measures of firm performance (“earnings metrics”) affect market price efficiency. In laboratory markets, we test the effects of salient earnings metrics, which vary in how they combine persistent and transitory elements, on investor information search, beliefs about value, offers to trade, and market price efficiency. We find that including transitory elements in salient earnings metrics causes traders to search unnecessarily for further information about these elements and to overestimate their effect on fundamental value relative to a rational benchmark. In contrast, separately displaying persistent elements in earnings increases the accuracy of traders’ value estimates. Prices generally reflect traders’ beliefs about value, and prices are most efficient when transitory elements are excluded from earnings metrics entirely. Our study contributes to research on salience effects in financial reporting by showing that including transitory elements in salient earnings metrics causes inefficient information search and biased beliefs about value that can aggregate to affect market prices. We also contribute to research in experimental markets by showing that redundant disclosure is not always beneficial; redundant disclosure of transitory earnings elements, in particular, appears to have negative consequences for investor behavior and market efficiency.     

Vertical Product Differentiation and Advertising

A duopoly model is developed in which firms' strategic variables include brand quality, the number of distinct market segments to enter and price. Informative advertising is used to overcome consumer ignorance about brands. In contrast to many existing models in which firms engage in price competition, the subgame perfect equilibria of the game are not characterised by the production of vertically differentiated products. Further, whilst the firms typically produce identical high quality products, in some circumstances the production of homogeneous low quality brands can be an equilibrium strategy.     

On the measurement of product quality in intra-industry trade: An empirical test for China

A relatively recent development in the intra-industry trade (IIT) literature is the measurement of the simultaneous import and export of quality-differentiated products, commonly known as vertical and horizontal IIT. A recent paper from Azhar and Elliott [Azhar, A. K. M. & Elliott, R. J. R. (2006), On the Measurement of Product Quality in Intra-Industry Trade, Review of World Economics, Vol 142 no 3, pp 476–495] analyses various approaches for disentangling vertical and horizontal IIT and suggests a complementary methodology. To investigate the robustness and sensitivity of the existing approaches we examine data on the nature of trade flows between China and its East Asian neighbours and show that in 2002 China tended to export low quality versions of its manufactured goods to Malaysia, Thailand and the Philippines.     

Inefficient Public Provision in a Repeated Elections Model

We consider a dynamic setting with no policy commitment. Two parties that compete for election must choose the level of provision of a public good as well as the tax payment needed to finance it. The cost of producing the good may be high or low and this information is not known to the voters. We show that there exists an equilibrium in which the party that does not want much of the public good uses the inefficient (high cost) technology even though the efficient one is available. Using the low cost technology would, by informing the voters about the cost parameter, force it to produce an excessively high level of the good in the future. Interestingly, this equilibrium is not symmetric, suggesting that a party with a strong taste for the public good is less likely to adopt a wasteful policy.
