Union Coverage Differentials. Some Estimates for Britain Using the New Earnings Survey Panel Dataset

This paper reports individual-level estimates of union/non-union wage differentials, using coverage information from the New Earnings Survey Panel Dataset. There are no existing panel estimates for the United Kingdom. Of a number of findings, the more important are (i) fixed-effects estimates are about one-half the equivalent cross-section estimates; (ii) the biggest differentials are for ‘company/district/local only’ agreements; and (iii) the differential is counter-cyclical. Also the effect of the 1979/82 recession was probably dampened by anti-union legislation, and the upward trend between 1975 and 1995 is due to the decentralization of collective pay bargaining.     

Declining Union Density in the 1980s: What Do Panel Data Tell Us?

In this paper we analyse data from the 1980—4 WIRS panel for the light they can shed on the causes of the decline in aggregate trade union density in the UK. We argue that, contrary to conventional wisdom, intra-establishment union density did, on average, decline between 1980 and 1984. This suggests that a traditional compositional change story is untenable. We proceed to investigate the correlation of intra-establishment change with variables suggested by the various hypotheses advanced to explain declining density over the period. We find some evidence for an influence of intra-establishment compositional changes, but the most statistically significant variables are wages and unemployment. These take the wrong sign, however, to support the business cycle interpretation of falling aggregate union density.     

Differences between students and non‐students' willingness to donate to a charitable organisation

• This paper reports on a comparative study of students and non‐students that investigates which psycho‐social factors influence intended donation behaviour within a single organisation that offers multiple forms of donation activity. Additionally, the study examines which media channels are more important to encourage donation. A self‐administered survey instrument was used and a sample of 776 respondents recruited. Logistic regressions and a Chow test were used to determine statistically significant differences between the groups. For donating money, importance of charity and attitude towards charity influence students, whereas only importance of need significantly influences non‐students. For donating time, no significant influences were found for non‐students, however, importance of charity and attitude towards charity were significant for students. Importance of need was significant for both students and non‐students for donating goods, with importance of charity also significant for students. Telephone and television channels were important for both groups. However, Internet, email and short messaging services were more important for students, providing opportunities to enhance this group's perceptions of the importance of the charity, and the importance of the need, which ultimately impacts on their attitudes towards the charity. These differences highlight the importance of charities focussing on those motivations and attitudes that are important to a particular target segment and communicating through appropriate media channels for these segments.

Error or absurdity? A non-cognitive approach to commodity fetishism

Abstract

Karl Marx presented his theory of commodity fetishism as an explanation of the mysterious appearance of social relations in a system of commodity production as natural phenomena. The standard interpretation of this as a failure to perceive capitalist social relations correctly depends on a particular modern sense of ‘natural’. If classical political economy and Marx used ‘natural’ in the Aristotelian sense, commodity fetishism appears quite differently: not as a cognitive error but rather as a manner of living under commodity production, one that is not wrong but absurd, the word fetishism tying commodity production to pre-Enlightenment, preliterate peoples.     

Exactly distribution-free inference in instrumental variables regression with possibly weak instruments

This paper introduces a rank-based test for the instrumental variables regression model that dominates the Anderson–Rubin test in terms of finite sample size and asymptotic power in certain circumstances. The test has correct size for any distribution of the errors with weak or strong instruments. The test has noticeably higher power than the Anderson–Rubin test when the error distribution has thick tails and comparable power otherwise. Like the Anderson–Rubin test, the rank tests considered here perform best, relative to other available tests, in exactly identified models.     

Nutrition Ad Claims and Disclosures: Interaction and Mediation Effects for Consumer Evaluations of the Brand and the Ad

The effects of ad disclosure information on evaluations of the brand, the advertisement, and purchase intentions are postulated to vary across different ad claim types. In addition, consumers' product health perceptions are hypothesized to mediate the effects of the disclosure information and ad claim type on brand and ad-related evaluations. Results from a between subjects' experiment show that the health perception measure mediates the effect of the disclosure on brand and ad evaluations, but the interaction between the ad claim type and the disclosure is not mediated by the inclusion in the model of consumers' product health perceptions.     

The Determinants of Price in Internet Auctions of Used Cars

This study analyzes how auction, seller, and product factors influence the price premium in an eBay used car auction market. In auctions with at least one bid, the reputation of the seller, title status, and the time the auction ended influenced the price premium on the highest bid. For auctions that resulted in a sale, cars with clear title and dealers were able to secure significantly greater price premiums, but seller reputation had no significant effect. Using a binary logit model, cars had a greater probability of selling if the seller had a better reputation. The quality of the presentation and number of pictures did not enhance the price premium in any of the models.

Developing country debt: implications for agricultural trade

There has been a sharp decline in the rate of economic growth in many developing countries in the 1980s compared with the 1970s. Reduced availability of external finance following the international debt crisis has been identified as one of the most important factors responsible for this decline. At the same time there has been a slowdown in the rate of growth of food imports to these countries, particularly to the highly indepted ones. The focus in the paper is on the implications for international agricultural commodity markets of a dept write-off in developing countries. To analyse these implications a world agricultural trade model is used. Specifically, the analysis covers the effect of existing debt on the permanent incomes of developing debtor countries and developed creditor countries, and hence the effect on agricultural commodity markets. The results indicate that, if the debts of the developing countries were written off, prices would improve in consequence of the resulting rise in their permanent incomes. If the debt write-off also led to growth in developing countries returning to the levels prevalent before the debt crisis, the improvements in world prices would be likely to be much larger.
