We set up a theoretical model to analyze the implications of coordination of immigration policies among destination countries. The model contains two types of spillovers between destination countries: a terms-of-trade externality and a welfare-policy externality. We show that while coordination unambiguously increases welfare of the destination countries, the effects on the level of immigration and on the income distribution of natives are ambiguous. Thus, coordination among destination countries does not necessarily solve the global coordination problem of inoptimally low levels of migration.  相似文献

On the Determinants of Mandatory Works Councils in Germany   总被引:1,自引:0,他引:1  
German works councils are often thought of as operating in all firms that exceed the basic size threshold (of five permanent employees) established under law. Drawing on a new large-scale, representative German data set, we report that only one-fifth of firms in our sample have works councils even if such firms do account for almost three-fourths of employment. The principal factors behind works council presence emerge as fairly conventional: firm size, firm age, branch plant status, the gender composition of the work force, and certain working arrangements. There are also signs of a close relation between workplace union density and council presence. However, some controversial causal links suggested in an earlier econometric literature receive little support.  相似文献

This paper provides a brief review of the empirical evidence on union productivity effects in Germany. The influence of trade unions on productivity is the net effect of conflicting forces which can lead to higher or lower productivity. Although the German dual system of workers' representation via unions and works councils is quite favourable to the existence of productivity-enhancing 'voice' effects, various empirical studies have not been able to detect significant positive net effects of these institutions on productivity.  相似文献

The returns earned by U.S. equities since 1926 exceed estimates derived from theory, from other periods and markets, and from surveys of institutional investors. Rather than examine historic experience, we estimate the equity premium from the discount rate that equates market valuations with prevailing expectations of future flows. The accounting flows we project are isomorphic to projected dividends but use more available information and narrow the range of reasonable growth rates. For each year between 1985 and 1998, we find that the equity premium is around three percent (or less) in the United States and five other markets.  相似文献

International assignees face cultural adjustment challenges in their host countries in work and nonwork situations. At the same time, social capital theory suggests that individuals can access and mobilize resources from their social networks. We explore the use of social networks by international assignees from a non-governmental organization in their cross-cultural adjustment to the host country. Specifically, we are interested in the individuals who directly provided support to the expatriate, a network that we term the ‘current assignment support network’. We focus on the size, type and frequency of contact of the international assignee's support network, and investigate to what extent these variables can predict overall cultural adjustment to the host country, or separate dimensions of cultural adjustment such as interaction adjustment, general adjustment and work adjustment. Our findings indicate that certain characteristics of the international assignee's current assignment support network do impact their cultural adjustment to the host country, but that the effects are moderated by whether the assignee has prior international experience.  相似文献

Objectives Currently, patients with persistent moderate-to-severe house dust mite (HDM) allergic rhinitis despite use of symptom-relieving medication can be offered subcutaneously administered allergy immunotherapy (SQ SCIT; Alutard SQ) as standard care of treatment in Denmark. Recently, a HDM sublingually administered allergy immunotherapy tablet (SQ SLIT-tablet; ACARIZAX) has been developed for at-home treatment. The purpose of this analysis is to compare the costs related to treatment and administration of SQ SLIT-tablet and SQ SCIT.

Methods Assuming equal efficacy between ther SQ SLIT-tablet and SQ SCIT, the cost-minimization analysis was the most appropriate for the comparison. According to guidelines and Summary of Product Characteristics, the treatment duration of SQ SLIT-tablet is 3 years and 3–5 years for SQ SCIT. The courses of treatment vary among patients and, therefore, the costs of treatment have been calculated for an average patient with HDM respiratory allergic disease (RAD) receiving either SQ SLIT-tablet or SQ SCIT. All costs associated with allergy immunotherapy were collected, i.e., cost of medication, administration and treatment setting, and discounted according to Danish guidelines. Comprehensive univariate sensitivity analyses were carried out.

Results The treatment costs for an average patient with HDM RAD are €3094 for SQ SLIT-tablet and €3799 for SQ SCIT; however, when adding indirect costs to the calculations the total costs of the treatments are €3697 and €6717 for SQ SLIT-tablet and SQ SCIT, respectively. Therefore, if 2500 patients with HDM RAD were treated with SQ SLIT-tablet instead of SQ SCIT, it would elicit a saving to the healthcare system of ~€1.8 million. The conclusion was robust to any changes in the sensitivity analysis.

Conclusion With regards to the cost of treating Danish patients with HDM RAD, it is clearly cost-saving to treat patients with SQ SLIT-tablet compared to SQ SCIT.  相似文献
