Informal Food Production in the Enlarged European Union 总被引:1,自引:0,他引:1
How widespread is the production of food in old and new member states of the European Union and what is the social meaning or logic of such activities? We show that growing food is (a) more widespread in former communist countries than in traditional market economies and (b) is predominantly a hobby or recreational activity in affluent countries, but a coping strategy in reaction to experienced difficulties in making ends meet in poorer nations, and especially so in the former communist countries. 相似文献

The paper presents a model of a non-resident father’s child support and contact with his child, which combines the public
good treatment of “child quality” with “trade” in father–child contact time in a setting of non-cooperative interaction. It
predicts that father’s income and mother’s non-labour income should have exactly the same effect on the frequency of father–child
contact if he chooses to make lump sum payments to the mother. If he does not or there is a binding child support payment
order, they have effects opposite in direction. A higher binding support order reduces father–child contact but may well raise
“child quality”.

A single latent variable model of health status and therapeutic health care utilization is estimated for parents and own children
of 6,557 US households. The equation system that identifies latent health status simultaneously determines a number of indicators
of general health, including presence of morbidity symptoms, mobility limitations, medication needs, and utilization of therapeutic
health care services. The main goal of the paper was to obtain an unbiased estimate of parents’ marginal substitution rate
between own and child health. Results indicate that parents’ valuation of their children’s health exceeds their valuation
of own health by almost twofold on average.

We investigate the impact of health shocks on wealth, using all four waves of the Health and Retirement Study, and estimate
not only the short-term effect but also the long-term effect of health shocks on wealth of the elderly. We find that new health
events lower wealth in elders during the period in which such health shocks occur, but the impact tends to disappear over
time. We also find that health shocks result in greater wealth depletion when they occur later in life. Together with existing
health problems, the overall impact of health problems on wealth increases over time.

This paper examines the nonmarket interactions among migrants in the urban labor market of Bangkok, Thailand. We test whether
the population size and the labor-market performance of previous migrants have externalities to new migrants who have moved
from the same province of origin. Our empirical results, which control origin fixed effects, time fixed effects, and origin-
and year-specific correlated shocks, show that (1) the relative population size of previous migrants in the market decreases
the employment probability of new migrants (substitution effect), (2) the employment probability of previous migrants increases
that of new migrants (positive externalities), and (3) when the employment probability of previous migrants is high, however,
the scale effect becomes positive, which demonstrates a threshold in the informational scale economies. The results imply
that positive informational scale effect dominates negative substitution effect when the efficiency of previous migrants is
sufficiently high in the destination labor market.

An early age at first marriage is known to be associated with a high risk of divorce. Yet, it has been suggested that beyond
a certain point, the relationship between age at marriage and marital instability may become positive because as unmarried
women begin to hear their biological clock tick, they may settle for matches far from the optimal. Analyses based on cycles
5 and 6 of the National Surveys of Family Growth show that the relationship between age at marriage and marital instability
is strongly negative up to the late 20s, with a flattening of the curve thereafter.

Given that savings behaviour and worker productivity have strong life-cycle components and given that demographic profiles
vary across countries, population age structure should be linked to differences in levels of economic development. In this
paper, we measure the economic importance of age structure variation for the global economy. We find that demographic maturation
has been associated with nearly half of the evolution of global per capita GDP since 1960. We also find that age structure
differences can account for just over half of the variation in worldwide per capita GDP (i.e. the lack of sigma convergence)
observed since 1960.

An ecological evolutionary viewpoint offers new perspectives on contemporary demographic problems in general and on population–environment issues in particular. In turn, rich and detailed human demographic data can help solve problems of interest in evolutionary theory. Such data have been analyzed in greatest detail in studies of traditional and historical societies. Evolutionary approaches using historical data go beyond small‐sample anthropological studies to the application of the evolutionary approach to large datasets, and illuminate important similarities between small‐scale traditional societies and large modern populations living in evolutionarily novel environments. This article provides a concise update of the breadth of questions and hypotheses of likely interest to demographers and others that evolutionary theorists address using a variety of traditional and historical datasets. It suggests opportunities for additional collaborative work between evolutionary theorists and historical demographers and highlights topics relevant to modern demography. 相似文献
