Policies over time and pareto optimality

This paper is concerned with sequences of policies that occur over time in voting models and planning procedures. The framework for our analysis includes assumptions that are satisfied by models in the corresponding literatures, together with other standard assumptions for microeconomic analysis that involve time. The starting point for our analyses is the prespective that results from combining the following (widely held) views: 1) certain voting models and planning procedures can be interpreted as being non-tatonnement or sequential processes (where each policy in the sequence that is generated is actually experienced by voters or consumers) and 2) an alternative being Pareto optimal in any given period (temporal Pareto optimality) is the appropriate efficiency criterion only if the alternative is the final outcome from a tatonnement process-and that, otherwise, one should examine the efficiency of the entire path (using intertemporal Pareto optimality). Our first observation about the planning literature is that is has (by and large) neglected the efficiency criterion that is appropriate for the discrete-time procedures that can be interpreted as non-tatonnement or sequential processes-and that, what's more, such trajectories will (in general) fail to meet this criterion. Our second observation identifies some results that can be used to establish that some of these trajectories will at least be ultimately intertemporally Pareto optimal. In our discussion of voting theory, we review Buchanan's opposition to requiring (social) choice consistency for voting procedures-and his argument for this position on (Pareto) efficiency grounds. We then consider voting procedures that can be interpreted as non-tatonnement or sequential processes and arrive at the conclusion that, in these cases, (i) majority rule cycles are intertemporally Pareto inefficient and (ii) achieving intertemporal Pareto optimality requires choice consistency. We then go on to show that related observations apply to Kramer's normative conclusions about his dynamical model of political equilibrium — and identify some further references where similar observations apply. In the final part of our discussion of voting models, we arrive at the further conclusion that, in the most relevant cases, a trajectory that stays in the temporal Pareto set is not necessarily more desirable (on efficiency grounds) than one that doesn't.This paper has been improved by helpful comments and suggestions that have been provided by Kenneth Arrow, an anonymous referee, and the editor who handled the paper.Peter Coughlin gratefully acknowledges financial support provided by (i) National Science Foundation Grant No. SES-8409352, and (ii) the Center for Advanced Study in the Behavioral Sciences at Stanford (with support from National Science Foundation Grant No. BNS-8700864 and the Alfred P.

When children’s testimonies are used as evidence: how children’s accounts may impact child custodial decisions

Abstract

In child custody cases, children oftentimes provide allegations of experienced trauma against one of their parents. Such allegations can happen before any investigative interviews (e.g., by the police or child protective services) have taken place. A central theme here concerns how to appraise such allegations and make certain that children’s accounts are taken seriously. In the current special issue, the focus is on new work on the functioning of children’s memory and its relation to trauma or work on children’s suggestibility and memory when they are traumatized. Specifically, key experts in the field of children’s memory provided contributions on: (1) the impact of interviewer support and rapport building on children’s testimonies, (2) the role of parental alienation in children’s testimonial accuracy, and (3) different types of false memories in children’s memory reports.     

Assessing the accuracy of Australia’s small-area population estimates

The Australian Bureau of Statistics provides population estimates of Statistical Local Areas annually. The accuracy of these estimates can be assessed after population estimates are rebased after each quinquennial Census of Population and Housing, however there appears to be no straightforward method of assessing these estimates. Errors that occur with population estimates can be attributed to several factors, both broad and specific to individual areas. These factors include inherent characteristics of the region, such as population size and growth rate; changes in the geographic boundaries; quality of input data; estimation method; and adjustments to control totals (state populations).     

Recent developments in aged care policy in Australia

A series of major reforms implemented through the mid 1980s sought to contain residential care and expand community care in Australia's long-term care system. While this goal has been maintained, a number of new policy initiatives followed the change of federal government in 1996. This article presents a systematic account of current policy objectives, implementation measures, and outcomes in three major policy areas: changing the balance between residential and community care, targeting in community care, and support for family caregivers. This analysis shows that while there have been shifts in emphasis from time to time, concerted policy efforts over the last 20 years have contained the growth of expenditure on long-term care and realized significant change in the service system.     

How Many Old People Use Community Services? A Review of Survey Findings

Several surveys of the aged have been conducted in Australia in recent years. They give rise to questions about the usefulness of their findings, particularly in determining the extent to which the aged use community services and in planning future services. This paper reviews the methods and findings of five of these surveys carried out between 1981 and 1986. It looks at the way questions were constructed, the time reference used, the populations and samples, problems of non-response and of definition. Explanations for the variability in reported service use are addressed. Finally, issues relating to the interpretation and application of survey findings are raised and discussed.     

Siblings as Confidants: Emotional Understanding, Relationship Warmth, and Sibling Self-Disclosure

Associations among (a) self-disclosures between early adolescent siblings, (b) emotional understanding, and (c) relationship warmth were investigated. Grade 5–6 children (M age = 11.5 years) were interviewed concerning the incidence of disclosures to closest-in-age siblings (20 = older, 20 = younger), feelings regarding disclosing (or not), and sibling relationship quality. Warmth was measured with the Sibling Relationship Questionnaire (Furman & Buhrmester, 1985) and emotional understanding was assessed with the Hypothetical Relationships Picture Task (adapted from Schneider, 1989, & Aquan-Assee, 1992). Hierarchical multiple regressions indicated self-disclosure was positively associated with feeling good about sharing and negatively associated with reports of not trusting or not receiving emotional support from their sibling. Sibling relationship warmth was a key characteristic associated with both emotional understanding and self-disclosure; female target children demonstrated greater emotional understanding. Warmth, but not emotional understanding, was associated with self-disclosure. Findings are discussed in light of the importance of links between affective relationships and children's social-emotional understanding.     

Ideology, domination and unemployment

Criticisms of the neo-Marxist dominant ideology thesis tend to under-emphasize the role which ideology plays in legitimating and sustaining systems of inequality, and instead to privilege explanations based on the ‘iron cage’ of economic and political relationships. A serious problem with some neo-Marxist analyses is the rather crude conceptualization of ideology which makes them susceptible to attack. Using material collected in Belfast amongst Protestant and Catholic working class, employed and unemployed, married men, this article seeks both to recast the notion of ideology, in particular to suggest that ideology would be better conceived not as a coherent, self-consistent system of ideas, but rather as a possibly contradictory set of themes whose primary importance lies in their specific, changing and tactical relationships to typical forms of practice, and also thereby to demonstrate how powerful and pervasive is the ideological dimension of domination.     

Family Support of the Aged: Some Evidence and Interpretation

This paper brings together a range of Australian material concerning family support for the aged. From a review of studies dealing with the family structure of the aged and accounts of inter generational contact and supportive exchanges within families, including migrant families, considerable evidence of family support is found. The implications of the absence of such support are seen from data on the use of services and admissions to institutional care; the preventive effect of marriage and family is apparent, those aged without family being identified as most at risk. Reasons for the commonly held view of family breakdown are then examined and some suggestions for service development outlined.
