Manumission in nineteenth-century Virginia

Using previously unexploited data, this paper explores the ages at which slaves were manumitted. OLS estimates reveal that mixed-race slaves, slaves in the tobacco-producing Piedmont, and female slaves of female slave owners were manumitted at younger ages. Weibull proportional hazards estimates imply that the same groups were more likely to be manumitted. The results also reveal a markedly diminishing likelihood of manumission after Nat Turner’s 1831 insurrection in south-central Virginia. The results are consistent with a principal–agent model in which slave owners contracted with slaves over consumption and future manumission to elicit effort and control shirking or other unproductive activities.     

The algebra of health concerns: implications of consumer perception of health loss,illness and the breakdown of the health system on anxiety

The current and expected future state of the American health care system creates much concern and anxiety at the national and individual level among Americans. This study is in response to the call of the Institute of Medicine to further study the lack of confidence among Americans about their future ability to receive high‐quality health care. This study compares perceived anxiety and its amelioration as a result of three possible health situations: illness with infectious disease, losing one's health and a breakdown of the health care system. This empirical study was conducted within the framework of conjoint analysis. We conducted an experimental design of ideas, identified attributes that increased or reduced anxiety in each of the three health‐related situations and then segmented consumers on the basis of their patterns of reactions to the attributes. We found that the highest anxiety was attributed to the breakdown of the health care system. The segmentation further suggested that the anxiety emerging from the breakdown of society's health care system generated a different extent of anxiety than that which emerged from one's illness or one's loss of own health. The attributes that drove anxiety across the health situations were, surprisingly, charities, one's company, the local hospital and supplemental insurance. Attributes that reduced anxiety differed among segments. The attributes were found to be: close friends, family, distribution of information by authorities and the belief in God. At a practical level, these data and patterns of response allow health care policy makers to enhance the coping ability of patients by understanding the nature of what reduces the anxiety of individual types of patients. The approach in this study provides a person‐centred system for communication and anxiety reduction that can be implemented as part of a public health policy.     

Reputation gaps and the performance of service organizations

Links between the reputation of organizations and their financial performance are intuitively attractive to assume, but often difficult to demonstrate convincingly. Gaps between employee and customer perceptions of corporate reputation have traditionally been associated with poor performance. In the context of service business and applying assimilation‐contrast theory, we hypothesize that the nature of such gaps will, in reality, have a differential effect on future revenue depending on the size and valence of the gap. The effects of small gaps should be assimilated by customers, but larger ones have a greater potential of creating a contrast effect resulting in significant increases or decreases in subsequent sales. In businesses where employees have a more positive view of the company reputation than customers, we hypothesize a growth in future sales, and where they have a relatively more negative view, a decline. We test the effects of what we label as reputation gaps in 56 business units drawn from nine service organizations and confirm our hypotheses. Among the implications of our findings are that managing reputation by elevating employee perceptions of a company's reputation above those perceived by its customers holds the potential to enhance future sales.

Time-consistent taxation in a dynastic family model with human and physical capital and a balanced government budget

Abstract .  This paper analyzes optimal, time consistent taxation in a dynastic family model with human and physical capital and with a balanced government budget. When tax revenue is used for publicly provided consumption or lump-sum transfers, leisure would be higher than its social optimum. Pareto optimal taxation requires taxing capital income more heavily than labour income and subsidizing investment at the same rate of the tax. Also, it requires either subsidizing labour at the same rate as a consumption tax or subsidizing consumption at the same rate as a labour income tax, and hence it is not a practical guide to policy. Further, a consumption tax, or equivalently a uniform income tax with investment subsidies at the same rate, can be improved on by taxing capital income more heavily than labour income.     

Research collaboration and behavioural additionality: A New Zealand case study

Generating the greatest benefit from public research programmes is a major aim for industry managers and policy administrators alike. However, how to measure whether benefit has occurred createsf a considerable dilemma for managers and policy-makers. One approach centres upon the concept of 'additionality' or 'what difference the policy has made'. Traditional 'input additionality' measures of subsequent research and development activity, for example, neither incorporate all impacts nor give adequate signals about adequate signals about aspects of 'output additionality', such as the impact on increased competitiveness at the level of the firm, or national competitiveness, the ultimate goal for the majority of research policies. An intermediate form of impact, 'behavioural additionality', centred upon changes in a firm's subsequent managerial behaviour, is considered to provide an alternative, yet compelling perspective on the impact of public support on the conduct of research. This study outlines empirical eveidence found for the various forms of additionality in a New Zealand collaborative research programme. It discusses how managers and policy administrators can exploit the occrrence of behavioural additionality to maximize the impact of a research policy, on the basis that modified behaviour is likely to strengthen a policy' latent abilityto influence the creation of output additionality. In such circumstances, the study suggests that managers and policy-makers should be identifying those interventions that lead to sustained improvements in mangerial practice, and in competitiveness, and should be managing their diffusion within firms and throughout industries.     

Gender and ethnic differences in factors that influence food intake

Abstract The objective of this research was to ascertain the gender-and ethnic-related factors that influence what one eats. This survey was conducted using a validated, pilot-tested questionnaire in 11 states and the District of Columbia, which were participating in the W-182 Western Regional Research project. The results indicated that the factors that influence what one eats differ by gender and ethnicity. Men were very much influenced by likes and dislikes, and by their spouse or significant other. Women were influenced by likes and dislikes, and health. Food likes/dislikes and concerns about health and weight were among the leading four factors for all ethnic groups. Food likes/dislikes were the top factor influencing what is eaten by 51% or more of Asians, Pacific Islanders, Caucasians and Hispanics. Concern about health was the top factor for 62% and 58%, respectively, of African Americans and Native Americans.
