Does Measurement Error Bias Fixed‐effects Estimates of the Union Wage Effect?

This paper compares estimates of the union wage effect using cross-section and panel estimators for male manual full-time and female employees using data from the British Household Panel Survey, 1991-1997. A comparison of cross-section and panel estimates suggests that unobserved heterogeneity biases cross-section estimates upwards. However, it is also found that the divergence between estimates is overstated because measurement error biases the fixed-effects estimates downward. Reducing measurement error in the union variable by taking averages and restricting changes in union status to occur only when a change in employer and/or job takes place increases fixed-effects estimates of the union wage effect.

Managing rewards to enhance relational worth

In this study, cognitive evaluation theory illustrates how the controlling aspects of reward redemption policy (stringent versus flexible) interact with the type of offered reward (social versus economic) to influence relational program effectiveness. We look at effectiveness by defining and measuring relational worth, the non-financial value of consumers to organizations. The hypotheses are empirically tested with a sample of season ticket holders of a professional sports team (n = 373) and then replicated in a second study with experimental data using scenarios in a hotel reward program context. Results indicate that perceived social rewards lead to affective commitment, while perceived economic rewards lead to continuance commitment. Involvement is a significant determinant in how reward type and policy influence commitment types; specifically, low-involvement consumers are more influenced by reward program signals than high-involvement consumers. Affective commitment produces the most relationally valuable consumer to an organization in terms of relational worth. Controlling policies have an undermining effect on all commitment types, regardless of reward type.

The estimation of union wage differentials and the impact of methodological choices

This paper demonstrates that methodological differences can matter a lot in the estimation of union/non-union wage differentials. Using individual-level data from the 1991 Wave of the British Household Panel Survey and a model evolved from replicating six existing British studies, we find that the model specification adopted has an important impact on the estimated differential and that the choice of which group means to use when evaluating the mean differential in multi-equation models is of considerable importance. There are also important differences between membership and coverage differentials and the earnings measure used and sample selected also make a difference. However, apart from firm size, the contents of the control vector used is not found to be of great importance.     

Intra-provincial inequalities and economic growth in China

This paper approaches the problem of inequalities in China. It is specifically focused on analyzing the effects of intra-provincial disparities on the development of the 28 mainland provinces in China. Intra-provincial inequalities, as measured by the Theil index, seem positively related to growth, albeit the results are only convincing for the coastal provinces. A case-by-case analysis, however, suggests highly diversified patterns, including linear or an inverted U-shape for the fastest growing coastal provinces and virtually no relationship for the majority of regions. The results corroborate some questions raised earlier about actual policy-making standards in China.     

Fish consumption: efficacy among fishermen of a brochure developed for pregnant women

The risk to human consumers from contaminants in fish is often dealt with by issuing consumption advisories, or in some cases, information brochures. Normally advisories and brochures are developed and tested with anglers. We examine the efficacy of a fish consumption brochure that was developed for pregnant women on people engaged in fishing in the Newark Bay Complex. The brochures were in English and Spanish, and subjects could read and be interviewed in either language. Of the 151 people interviewed, 32% were women, 58% spoke only English, 22% spoke mainly Spanish and the rest felt comfortable with both languages. There were no differences in the percent that were present as a function of preferred language. There were significant differences in the understanding of the brochure, depending upon preferred language (and the language of the brochure). In general, anglers preferring Spanish and who read the brochure in Spanish obtained fewer of the messages correctly than those who preferred English (seven of seven questions). There were also gender differences in efficacy of the brochures; a higher percentage of female anglers thought that the fish were not safe to eat from the port and thought that eating contaminated fish from the port could harm their baby. Although the correct message was obtained by 34–100% of the anglers, depending upon the question, and 60–75% of the anglers believed the pamphlet, only 16% (Spanish‐speaking) to 47% (Bilingual) planned on changing the species of fish they eat or the method of cooking. These data suggest that a pamphlet designed for pregnant women is useful for anglers, and they can obtain the ‘correct’ message from it. However, a relatively small percentage of subjects were persuaded to change their cooking or consumption behavior. In addition to television, subjects felt that the direct approach of distributing brochures face‐to‐face was an important method of communication of fish consumers.     

Role of self-caught fish in total fish consumption rates for recreational fishermen: average consumption for some species exceeds allowable intake

Studies of fish consumption focus on recreational or subsistence fishing, on awareness and adherence to advisories, consumption patterns, and contaminants in fish. Yet the general public obtains their fish from commercial sources. In this paper I examine fish consumption patterns of recreational fishermen in New Jersey to determine: (1) consumption rates for self-caught fish and for other fish, (2) meals consumed per year, (3) average meal size, and average daily intake of mercury, and (4) variations in these parameters for commonly-consumed fish, and different methods of computing intake. Over 300 people were interviewed at fishing sites and fishing clubs along the New Jersey shore. Consumption patterns of anglers varied by species of fish. From 2 to 90% of the anglers ate the different fish species, and between 9 and 75% gave fish away to family or friends. Self-caught fish made up 7–92% of fish diets depending upon species. On average, self-caught fish were eaten for only 2–6?months of the year, whereas other fish (commercial or restaurant) were eaten up to 10?months a year. Anglers consumed from 5 to 36 meals of different fish a year, which resulted in intake of mercury ranging from 0.01 to 0.22?μg/kg/day. Average intake of Mako shark, swordfish, and tuna (sushi, canned tuna, self-caught tuna) exceeded the US Environmental Protection Agency’s oral, chronic reference dose for mercury of 0.1?μg/kg/day. However, computing intake using consumption for the highest month results in average mercury intake exceeding the reference dose for striped bass and bluefish as well. These data, and the variability in consumption patterns, have implications for risk assessors, risk managers, and health professionals.     

Selenium:mercury molar ratios in fish from the Savannah River: implications for risk management

The risk to humans from contaminants in fish is dealt with by issuing consumption advisories, which are devised from consumption patterns, contaminant levels, and toxicity of those contaminants. The primary contaminant of concern in fish is mercury, and recently it has been suggested that the protective effects of selenium on mercury toxicity should be considered in risk management. The relationships between mercury, fish species and fish size, and selenium:mercury (Se:Hg) molar ratios were examined for freshwater fish from the Savannah River. The data indicated: (1) significant variation in Se:Hg molar ratios among and within species, (2) mean selenium molar ratios for the 11 species were negatively correlated with mean mercury levels and mean fish length, (3) greater variation in individual variances within species than the variation in mean ratios among species, (4) some species with high mean ratios had individuals with ratios below 1, and (5) even the species with the highest mean ratios had some individuals close to a molar ratio of one. These data suggest that the great variability of the Se:Hg molar ratios within a species results in the ratios being unpredictable. That is, knowing the mean Se:Hg molar ratio for a given species does not predict the ratios of individuals, or thus the protectiveness of selenium on mercury toxicity.     

The determinants of audit fees—evidence from the voluntary sector

Given the growing demand for accountability in the public sector, there is a need to begin to investigate audit pricing issues in this sector. This study makes three contributions. First, it develops and estimates, for the first time, a model of audit fee determinants for the charity sector. As in previous private sector company studies, size, organisational complexity and audit firm location are the major determinants. A positive association between audit fees and fees for non-audit services is also observed. Charity sector factors of empirical significance include the nature of the charity (i.e., grant-making or fund-raising), its area of activity and the importance of trading income. Separate models for grant-making and fund-raising charities reflect the relative complexity of the audit of fund-raising charities. Second, the lower auditor concentration in the charity sector market, compared to the private sector market, permits a more powerful test of whether large firms and/or auditor expertise are rewarded with a fee premium. In the more complex audit environment of fund-raising charities, the results show that Big Six audit firms receive higher audit fees (18.5%, on average) than non-Big Six firms. Also, non-Big Six audit firms with charity expertise are rewarded with a fee premium over other non-Big Six firms. Finally, the study demonstrates that the charity audit fee rate is significantly lower than that of private sector companies; in fact it is approximately half. A change in the reporting of charity audit fees is proposed to reflect any element of ‘charitable giving’ by the audit firm.
