Does immigration hamper union organizing in the United States? The prevailing literature strongly suggests that it does and for two reasons: first, immigrants increase the labor pool and diminish union influence over the labor market. And second, immigrants may be harder to organize than native workers. In this dominant view, unions are well served to restrict immigration and have always done so. But how, then, to explain the fact that American labor has long been deeply divided over the response to immigration? Drawing on new archival research and interviews, this paper uncovers a neglected side of American labor history in which many union leaders have extended solidarity to immigrants and sought to organize them. Moreover, analysis of time series data on immigration and union density corroborates the implicit theory of this alternate account of labor history: immigration has, in fact, no statistically significant effect – either positive or negative – on union density over time. Depending on specific conditions and strategies, unions can and have been successful in organizing during periods of high immigration. 相似文献

Spain underwent two major labour reforms in 2010 and 2012 under the assumption that deregulating the labour market and decentralizing collective bargaining would automatically reduce unemployment (deregulation hypothesis). This article highlights the impact of demand and the sectoral structure of the economy to explain the behaviour of this variable (structural hypothesis). Analysing subnational panel data, the authors assess the capacity of these two hypotheses to explain unemployment trends. Their results cast doubt on the deregulation hypothesis and indicate the importance of cyclical and structural factors. 相似文献

Summary. We consider estimation of the causal effect of a treatment on an outcome from observational data collected in two phases. In the first phase, a simple random sample of individuals is drawn from a population. On these individuals, information is obtained on treatment, outcome and a few low dimensional covariates. These individuals are then stratified according to these factors. In the second phase, a random subsample of individuals is drawn from each stratum, with known stratum-specific selection probabilities. On these individuals, a rich set of covariates is collected. In this setting, we introduce five estimators: simple inverse weighted; simple doubly robust; enriched inverse weighted; enriched doubly robust; locally efficient. We evaluate the finite sample performance of these estimators in a simulation study. We also use our methodology to estimate the causal effect of trauma care on in-hospital mortality by using data from the National Study of Cost and Outcomes of Trauma. 相似文献

This article examines Cashflow, a board game that readers of best-seller financial success books play in order to learn the basics of investing and to enhance
their financial skills. Cashflow is a fictitious market, in which players buy and sell assets with the ultimate goal of becoming
“financially free.” Based on participant observation of clubs in the United States and Argentina, and drawing on the ideas
of performativity and governmentality, the article focuses on four topics. First, the role of the game in establishing definitions
of what it means to be rich. Second, the development of calculative tools. Third, players’ work on the self, through which
they explore what may be fostering or limiting their chances of financial success. Finally, the work done by players to fit
the game with reality, which allows the game to be used in different national economic contexts. 相似文献

Important empirical information on household behavior and finances is obtained from surveys, and these data are used heavily
by researchers, central banks, and for policy consulting. However, various interdependent factors that can be controlled only
to a limited extent lead to unit and item nonresponse, and missing data on certain items is a frequent source of difficulties
in statistical practice. More than ever, it is important to explore techniques for the imputation of large survey data. This
paper presents the theoretical underpinnings of a Markov chain Monte Carlo multiple imputation procedure and outlines important
technical aspects of the application of MCMC-type algorithms to large socio-economic data sets. In an illustrative application
it is found that MCMC algorithms have good convergence properties even on large data sets with complex patterns of missingness,
and that the use of a rich set of covariates in the imputation models has a substantial effect on the distributions of key
financial variables. 相似文献

Given the high population and development density in Hong Kong, building failures can result in catastrophic consequences.
It is thus worthwhile identifying those dilapidated buildings, and this explains why the Hong Kong government has considered
launching a mandatory building inspection scheme in the city. Apart from the measurement of building safeness, however, it
is equally important to explore the major determinants of the safety performance of buildings. Such information can help the
government and other related organizations to rationalize their subsidies offered for building improvement and to make more
informed strategies of urban regeneration in Hong Kong. To this end, the safety performance of 429 private multi-storey residential
buildings was measured in this study using the Building Safety and Conditions Index developed by The University of Hong Kong.
It was then followed by an explanatory analysis which found that older buildings were less safe than large, modern buildings.
More importantly, the co-existence of a property management agent and a statutory owners’ association delivered the best building
safety performance, and in this respect was the optimum building management regime for private multi-storey buildings in Hong
Kong. These findings pose significant policy implications for building safety and urban regeneration in Hong Kong. 相似文献
