A flood of emigration from Hong Kong to Canada was observed prior to the handover from Britain back to China in 1997. I pool Canadian Census data from 1991 to 2006 to study the labour market assimilation of Hong Kong immigrants. The findings suggest that these immigrants faced a significant negative wage gap upon entry in comparison with Canadian‐born individuals, and this was larger for cohorts arriving closer to 1997, suggesting a decline in cohort quality. The results also indicate that earnings convergence with the Canadian‐born was slow for the majority of these immigrants.  相似文献

The variation in legal system quality across states in Mexico is used to examine the relationship between judicial quality and firm size over the course of the 2000s, when systemic changes were taking place. Using economic census microdata and survey‐based measures of legal institutions, a robust effect of judicial quality is observed on the firm size distribution and efficiency, instrumenting for underlying historical determinants of institutions. Indicative evidence is found that the effect is strongest in more capital‐intensive industries. Market size and distance‐to‐market are also found to matter for firm size outcomes, consistent with the new trade literature.  相似文献

Abstract

Parents play a critical role in promoting fruit and vegetable consumption, for eating patterns established early in life tend to persist into adulthood. Despite this, the factors that facilitate or inhibit parents’ capacity to socialise fruit and vegetable consumption into their children’s daily diets remain poorly defined. Thirty-eight semi-structured interviews with residents, allied healthcare professionals, community leaders, community programme leaders and a local government leader living or working in two low socioeconomic suburbs were consequently conducted to ascertain factors exogenous and endogenous to the family unit that shaped parental food socialisation practices. Budgetary and time constraints emerged as exogenous factors that constrained fruit and vegetable socialisation. Constraining effects were also found for a range of endogenous factors, including commensal experiences, children’s food fussiness and the feeding styles employed by parents. As such, while many caregivers may wish to socialise fruit and vegetable consumption into their children’s daily diets, their capacity to do so is often inhibited by factors beyond their volitional control. Failure to take heed of these factors could therefore result in the development of social marketing campaigns that are ineffective at best or give rise to unintentionally harmful outcomes at worst.  相似文献

This article explores the use of alternative payment mechanisms to overcome the holdout problem when multiple parcels of land must be acquired to complete a real‐estate development project. Purchase offers contingent upon successful land aggregation are compared to combination offers containing both guaranteed and contingent payments to determine which approach better mitigates holdout. The distribution of gains between developers and landowners is also examined. The results of a series of economic experiments suggest that contingent offers expedite land aggregation but developer payoffs are higher when combination offers are used. The results offer insight to real‐estate developers participating in land aggregation and inform government entities considering the necessity of public‐sector intervention in real‐estate markets to encourage desired development projects.  相似文献

Since 1990 the Cuban economy has faced a crisis comparable with those in Eastern Europe. However, since 1995 approximately, the Cuban reform has been showing significant results in terms of economic recovery and financial adjustment. As is the case with the Chinese reform, the stabilising, privatising and liberalising measures taken in Cuba point to a reform strategy essentially different from that followed in Eastern Europe. This article shows two relevant aspects of the Cuban case: first, the Cuban reform is a transition process toward the market although forced by external circumstances and still at an early developmental stage; second, the Cuban transition is in line with the evolutionary conception of a transition.  相似文献

Abstract

In a recent paper, Johar and Sirgy have proposed a hypothesis that value-expressive advertising appeals are persuasive when the product is value-expressive, whereas utilitarian appeals are persuasive when the product is utilitarian. Johar and Sirgy suggested that future research be directed at testing these hypotheses. This comment points out that direct support for these hypotheses already exists. The experimental evidence in support of these and related predictions is discussed. Suggestions for future research on the effectiveness of utilitarian versus value-expressive appeals are offered.  相似文献
