This paper develops and estimates models of family and sex-specific emigration, as well as the sex composition of this emigration, from 12 European source countries to the U.S. for the period 1870–1910. The models are based on the distinction between economic migrants (males, single females, and some married females) and tied or trailing migrants (females) and are estimated with panel data, including data that relate to the occupational/industrial structure of male and female economic activity in source countries. Hausman-Taylor instrumental variable estimates suggest that although both males and females responded to labor-market signals, males were more responsive than females to per capita GDP differences. Moreover, compared to the rest of Europe, Ireland, and Scandinavia were the sources of many young, single male, and female migrants, who responded strongly to gaps in economic opportunities. In fact, much of the European response to such gaps appears to be due to migrants from Ireland and Scandinavia. Females tended to originate in English-speaking countries and countries that were agriculturally oriented. Service and manufacturing jobs in source countries discouraged the migration of females relative to males. Males tended to follow recent migrants more than females, but females responded more to long-term influences as measured by stocks of migrants from their source countries who had previously settled in the U.S. Countries with high birth rates had relatively fewer female emigrants, whereas those with high rates of natural increase 20 years earlier experienced relatively more male emigration. Intact families, other family members (including family-strategy male migrants and trailing female migrants), and single males and females responded strongly to economic incentives, but the singles were most responsive followed by family-strategy males.  相似文献

Spreads, depths, and the impact of earnings information: an intraday analysis   总被引:19,自引:0,他引:19  
For a sample of NYSE firms, we show that wide spreads are accompaniedby low depths, and that spreads widen and depths fall in responseto bigger volume. Spreads widen and depths fall in anticipationof earnings announcements; these effects are more pronouncedfor announcements with larger subsequent price changes. Spreadsare also wider following earnings announcements, but this effectdissipates quickly after controlling for volume. Collectively,our results suggest liquidity providers are sensitive to changesin information asymmetry risk and use both spreads and depthsto actively manage this risk.  相似文献

Health is one of the crucial problems confronting the development of Third World countries. Community‐based primary health care is the best instrument for mobilising community development.Development through health, however, can only be achieved if primary health care is implemented in a comprehensive approach in which a supportive environment and living conditions are as important as the provision of health care services. The Venda care group organisation, like other village health workers, is involved in primary health care and community development in the communities of the care groups. Such supportive community‐based organisations are able to alleviate health and development problems at the grass roots provided that programmes and activities are based on community participation, self‐reliance and the development of local decision‐making and leadership skills. The degree of success of the Venda care group organisation in achieving these objectives was investigated.  相似文献

This article develops a model of three faces of labor from Figart, Mutari, and Power’s three faces of wages. This is integrated with sustainability models to locate the process of human and social capital formation and explore issues arising from technological change. The latest wave of automation, involving robotics and artificial intelligence, is expected to be an even greater challenge for worker well-being than globalization and immigration. The model supports a new narrative around labor that incorporates the caring economy as well as a framework for thinking about labor issues and long-term well-being.  相似文献

Bubbles for Fama     
We evaluate Eugene F. Fama's claim that stock prices do not exhibit price bubbles. Based on US industry returns (1926?2014) and international sector returns (1985?2014), we present four findings (1) Fama is correct in that a sharp price increase of an industry portfolio does not, on average, predict unusually low returns going forward; (2) such sharp price increases predict a substantially heightened probability of a crash but not of a further price boom; (3) attributes of the price run-up, including volatility, turnover, issuance, and the price path of the run-up, help forecast an eventual crash; and (4) these attributes also help forecast future returns. Results hold similarly in US and international samples.  相似文献

Alcohol consumption is a function of social dynamics, environmental contexts, individuals' preferences and family history. Empirical surveys have focused primarily on identification of risk factors for high-level drinking but have done little to clarify the underlying mechanisms at work. Also, there have been few attempts to apply nonlinear dynamics to the study of these mechanisms and processes at the population level. A simple framework where drinking is modeled as a socially contagious process in low- and high-risk connected environments is introduced. Individuals are classified as light, moderate (assumed mobile), and heavy drinkers. Moderate drinkers provide the link between both environments, that is, they are assumed to be the only individuals drinking in both settings. The focus here is on the effect of moderate drinkers, measured by the proportion of their time spent in “low-” versus “high-” risk drinking environments, on the distribution of drinkers.A simple model within our contact framework predicts that if the relative residence times of moderate drinkers are distributed randomly between low- and high-risk environments then the proportion of heavy drinkers is likely to be higher than expected. However, the full story even in a highly simplified setting is not so simple because “strong” local social mixing tends to increase high-risk drinking on its own. High levels of social interaction between light and moderate drinkers in low-risk environments can diminish the importance of the distribution of relative drinking times on the prevalence of heavy drinking.  相似文献

English National Health Service Foundation Trusts are subject to a regulatory regime in which the level of monitoring and intervention is determined by performance against two key performance metrics: a ‘financial risk rating’, based on a number of performance metrics, such as the reported surplus margin and return on assets, and a ‘prudential borrowing limit’. In this paper, we investigate the variation in financial reporting quality, proxied by discretionary accruals, with the incentives introduced by this regime. We find: first, that discretionary accruals are managed to report small surpluses; second, that, consistent with the avoidance of regulatory intervention in both the short and medium term, discretionary accruals are more positive when pre-managed performance is below intervention triggering thresholds and more negative when well above threshold; third, that, despite a move away from financial breakeven as the primary performance objective, there remains an aversion to small loss reporting. We further find that the level of discretionary accruals is driven by two metrics of strategic significance: the surplus margin (a measure of retained earnings) and the prudential borrowing limit (a measure of borrowing capacity).  相似文献

We investigate the informational efficiency of mutual fund performancefor the period 1965-84. Results are shown to be sensitive tothe measurement of performance chosen. We find that returnson S&P stocks, returns on non-S&P stocks, and returnson bonds are significant factors in performance assessment.Once we correct for the impact of non-S&P assets on mutualfund returns, we find that mutual funds do not earn returnsthat justify their information acquisition costs. This is consistentwith results for prior periods.  相似文献
