Choosing to Keep Up with the Joneses and Income Inequality
We study a variant of the conventional keeping-up-with-the-Joneses setup in which heterogeneous-ability agents care both about consumption and leisure and receive an utility premium if their consumption exceeds that of the Joneses'. Unlike the conventional setup in which all agents are assumed to want to participate in the rat race of staying ahead of the Joneses, our formulation explicitly permits the option to drop out. Mean-preserving changes in the spread of the underlying ability distribution, via its effect on the economy-wide composition of rat-race participants and drop-outs, have important consequences for induced distributions of leisure and income, consequences that are unobtainable using conventional keeping-up preferences.keeping up with the Joneses; consumption externalities; leisure; labor supply
Deviant Generations, Ricardian Equivalence, and Growth Cycles
TTwo equilibrium possibilities are known to obtain in a standard overlapping-generations model with dynastic preferences: either the altruistic bequest motive is operative for every generation (in which case, Ricardian equivalence obtains) or it is not, for any generation. Dynamic equilibria, where the bequest motive is occasionally operative, cannot emerge. This paper studies bequest-giving behavior and out-of-steady-state bequest and growth dynamics in a�Ak�model with intra- and inter-generational consumption externalities. These externalities, by their very presence, do not destroy Ricardian equivalence. They may, however, give rise to�deviant generations—generations that do not leave a bequest having received an inheritance, and vice versa—and that seals the fate for Ricardian equivalence. Consumption externalities may also generate interesting indeterminacies and endogenous growth cycles that did not exist otherwise.bequests; Ricardian equivalence; growth cycles; Consumption externality
Economic comparison of two methods of supplementary feeding in Finnish reindeer management
The most common methods are (1) supplementary feeding with dry hay (maximally 50 kg per head a season) on natural ranges in mid and late winter, and (2) corral feeding, where the reindeer are fed in small yard-corrals with hay, green silage, lichen, molasses and commercial reindeer feeds for 3-5 months a winter
Resurrecting equilibria through cycles in an overlapping generations model of money
Momentary equilibria are defined as points that satisfy agents’ optimality conditions and market clearing at any date. However, some dynamic sequences commencing from such points may not be considered valid equilibria because they asymptotically violate some economic restriction of the model. This paper studies a pure-exchange monetary overlapping generations economy in which young and old agents face exogenous minimum consumption requirements, and money is the only asset. The presence of the minimum consumption requirement on the old is shown to produce multiperiodic monetary equilibria in which real balances cycle forever between “momentary” equilibrium points (those which generate monetary sequences that potentially violate equilibrium strictures asymptotically). The novelty is to show that segments of the intergenerational offer curve that would have been deemed dynamically invalid can, in fact, be used to produce asymptotically valid cyclical paths. Indeed, a limit cycle can bestow dynamic validity on momentary equilibrium points that had erstwhile been classified as dynamically invalid
Choosing to keep up with the Joneses and income inequality
We study a variant of the conventional keeping-up-with-the-Joneses setup in which heterogeneous-ability agents care both about consumption and leisure and receive an utility premium if their consumption exceeds that of the Joneses\u27. Unlike the conventional setup in which all agents are assumed to want to participate in the rat race of staying ahead of the Joneses, our formulation explicitly permits the option to drop out. Mean-preserving changes in the spread of the underlying ability distribution, via its effect on the economy-wide composition of rat-race participants and drop-outs, have important consequences for induced distributions of leisure and income, consequences that are unobtainable using conventional keeping-up preferences
Early home-based recognition of anaemia via general danger signs, in young children, in a malaria endemic community in north-east Tanzania
BACKGROUND: Ethnographic studies from East Africa suggest that cerebral malaria and anaemia are not classified in local knowledge as malaria complications, but as illnesses in their own right. Cerebral malaria 'degedege' has been most researched, in spite of anaemia being a much more frequent complication in infants, and not much is known on how this is interpreted by caretakers. Anaemia is difficult to recognize clinically, even by health workers. METHODS: Ethnographic longitudinal cohort field study for 14 months, with monthly home-visits in families of 63 newborn babies, identified by community census, followed throughout April – November 2003 and during follow-up in April-May 2004. Interviews with care-takers (mostly mothers) and observational studies of infants and social environment were combined with three haemoglobin (Hb) screenings, supplemented with reports from mothers after health facility use. RESULTS: General danger signs, reported by mothers, e.g. infant unable to breast-feed or sit, too weak to be carried on back – besides of more alarming signs such as sleeping all time, loosing consciousness or convulsing – were well associated with actual or evolving moderate to severe anaemia (Hb ≤ 5–8 g/dl). By integrating the local descriptions of danger symptoms and signs, and comparing with actual or evolving low Hb, an algorithm to detect anaemia was developed, with significant sensitivity and specificity. For most danger signs, mothers twice as often took young children to traditional healers for herbal treatment, rather than having their children admitted to hospital. As expected, pallor was more rarely recognized by mothers, or primary reason for treatment seeking. CONCLUSION: Mothers do recognize and respond to symptoms and danger signs related to development of anaemia, the most frequent complication of malaria in young children in malaria endemic areas. Mothers' observations and actions should be reconsidered and integrated in management of childhood illness programmes
The impact of the physical environment for caregiving in ordinary housing: Experiences of staff in home- and health-care services
The strong driving forces for ageing in place demand sustainable solutions for the housing and care of older people and the health and safety of home- and health-care staff. The aim of the study was to elucidate staff experiences of providing home- and health-care to older people living in ordinary housing. This study was part of a larger project investigating the relation between home design and conditions for care in ordinary housing. The data were gathered through focus group interviews with staff in home- and health-care. Three main themes were found according to staff experiences of particular rooms’ sizes and proportions, spatial configurations, and aspects to consider when designing new housing. This study contributes important knowledge about essential features of the physical environment for staff providing home- and health-care for older people in their own homes and to aid the development of functionally sustainable housing to minimise injuries to staff
