We investigate whether recent changes in welfare policy affect the migration of low-educated unmarried mothers. Estimates indicate that welfare reform is associated with an increase in employment-related intrastate migration, and a decrease in non-employment related migration, both within and between states. The net effect was a small increase in intrastate migration and a small decrease in interstate migration. The close link between migration and employment suggests that welfare reform has motivated low-income women to move for economic reasons. In general, welfare policy appears to have a much larger effect on residential location because of its relationship to employment than because of benefit differences between states.  相似文献

The purpose of this research was to investigate the effects that user task load level has on the relationship between an individual's trust in and subsequent use of a system's automation. Military decision-makers trust and use information system automation to make many tactical judgments and decisions. In situations of information uncertainty (information warfare environments), decision-makers must remain aware of information reliability issues and temperate their use of system automation if necessary. An individual's task load may have an effect on his use of a system's automation in environments of information uncertainty.It was hypothesized that user task load will have a moderating effect on the positive relationship between system automation trust and use of system automation. Specifically, in situations of information uncertainty (low trust), high task load will have a negative effect on the relationship. To test this hypothesis, an experiment in a simulated command and control micro-world was conducted in which system automation trust and individual task load were manipulated. The findings from the experiment support the positive relationship between automation trust and automation use found in previous research and suggest that task load does have a negative effect on the positive relationship between automation trust and automation use. Experiment participant who incurred a higher task load exhibited an over-reliance on their automated information systems to assist them in their decision-making activities. Such an over-reliance can lead to vulnerabilities of deception and suggests the need for automated deception detection capabilities.  相似文献

Abstract State sponsored employment agencies are an important source of job matching in Britain. This study tracks Jobcentre use in Britain over the previous decade and the effectiveness of Jobcentre use in securing entry into employment for those who utilise its services. Amongst the unemployed, use of Jobcentres is highly counter-cyclical. This can be attributed principally to the changing composition of the stock over the economic cycle. In good times, there are relatively more short duration, voluntary quits in the stock, who tend to rely on Jobcentres least. Jobcentres are found to have a significant positive effect on the job entry rates of its clients. The greatest beneficial impact is amongst those, the low skilled and the long term unemployed with the lowest exit rates from unemployment.  相似文献

We estimate outflow equations for vacancies and unemployed workers in Britain, departing from the stock-based analysis of matching in two ways. First, we deal with the temporal aggregation problem that arises when discrete time data are used to describe continuous time processes. Second, we allow for a stock-flow matching mechanism in which the stock of traders on one side of the market matches with the flow of traders on the other side. Our estimates are in line with the predictions of stock-flow matching in terms of higher exit rates of flows and of matching combinations between labor market stocks and flows. Furthermore, employer search effectiveness did not seem to decline between the 1960s and the 1990s. Nevertheless, some deterioration in worker search effectiveness is detected, however less severe than that implied by previous, stock-based work.  相似文献

This article uses new data to analyze the impact on Southeast Asian urbanization of globalization and industrialization in the world economy's core countries between the 1870s and World War II. Dramatic falls in transport costs and free trade, enforced, if necessary, by colonial rule, combined to open vast frontier areas throughout Southeast Asia to global commerce and create a handful of large urban centres. These cities, through linking Southeast Asian primary commodity exporters to world markets, grew predominantly as part of the global economy. Our econometric analysis shows that measures of globalization — in particular industrial production in the world core and international transport costs — are much better predictors of the size of Southeast Asia's main cities than domestic factors such as total population, GDP per capita, land area or government expenditure.  相似文献

An important challenge in managing renewable resources is to understand why owners and managers sometimes make decisions that deplete resources and future earnings, such as when graziers allow pastures and land condition to be degraded. In this paper, we test two potential reasons for unsustainable management practices, myopia and salience, with each explaining why resource managers may exhibit impatience in harvest decisions. Myopia is associated with decision makers placing lower weight on future outcomes than would be implied by their pure time preference. Salience is associated with overweighting of consumption ‘now’, implying inconsistency in time preferences. To test for these effects on renewable resource management, an incentivised, dynamic field experiment was carried out with rangeland grazing enterprise owners in north‐eastern Australia that related management choices with uncertain rainfall events to both profits and land condition over time. Results demonstrate that respondents exhibiting myopia/salience in their choices tended to achieve lower cumulative scores in the experiment, as well as lower land conditions on their properties as measured with remote sensing data. Our results explain why there may be persistent optimisation failures by resource owners that reduce both profits and environmental outcomes.  相似文献

We use a framed field experiment considering hypothetical stocking rate decisions made by grazing enterprise managers and estimate non‐linear multinomial logit models for a range of nested non‐expected utility and expected utility models. The risk and decision‐bias parameters for five models estimated for individual responses are shown to be significantly related to land condition but in ways which suggest behavioural aspects of decision making are critical in understanding land management and stocking rate decisions. Our results show that individual heterogeneity in decision making amongst farming groups is likely to be a significant source of variation in farming intensity and technology adoption decisions. This heterogeneity does not appear to be a reflection of socio‐demographic characteristics. Furthermore, decision functions appear to be biased toward selection of simpler representative functions (e.g. Expected Utility) for sample averages. This suggests that experimental findings that Expected Utility is representative for actual decisions may be due to sample averaging rather than reflect actual behaviour.  相似文献

With 40% of the world able to access the internet, online marketplaces provide the small entrepreneur with a hitherto incomprehensible opportunity to reach a global audience with very low barriers to entry and low risk. Yet, academic research has not studied the factors unique to online businesses that affect their long-term survival. This study is the first of its kind that does so using data gathered from eBay’s feedback system in 2004, 2009, and 2013. The results present data on the rate of discontinuance of eBay ventures. Further, a logistic regression analysis suggests that unique factors such as venture size, age, and feedback reputation positively influence the likelihood of long-term survival of an eBay venture. Based on these results and the ensuing discussion, implications for researchers and practitioners are provided.  相似文献
