"This paper investigates individual intermunicipal migration behaviour in Canada within the context of a human capital model that adjusts for the migrant's selectivity in computing expected income gains. In addition to the typical regional determinants of migration, housing and labour market characteristics are found to influence intermunicipal migration significantly, the effects differing with age. Structural coefficients remained more or less stable during the decade 1971-1981. It is shown that the failure to adjust income gains for selectivity bias results in an underestimation of the migration-impacts of income gains and municipal-specific factors." 相似文献

The paper uses data from the 1976 Household Expenditure Survey (Susenas) to examine spatial patterns of poverty and inequality in Indonesia. A number of inequality measures are computed for each province (Gini Ratio. Atkinson Index, Theil Index, L-Index) and provincial rankings according to each index are compared. Provinces are also ranked according to a number of poverty indexes, using a poverty line adjusted for differences in price levels, between provinces. The correlation between selected measures of poverty and inequality is also investigated and some implications for regional development policy discussed. 相似文献

One of the major attributes determining system reliability, the one that has received the most thorough and systematic study for many years, is system survival function. A “survival function” is a mathematical formula relating the probability of satisfactory performance of a system to time. Here, probability of satisfactory performance is synonymous with probability of nonfailure or probability of survival of a performing system.In breakthrough analysis of complex technological systems, the situation is somewhat similar but opposite to the above system reliability case. For breakthrough forecasting, the problem is to determine the probability of occurrence of success of a nonperforming system. Thus this paper presents a quantitative methodology for forecasting technological breakthroughs using a new concept of “attainability function,” derived in a similar fashion as the “reliability function.” 相似文献

Analysis using firm-level data for a sample of 33,302 firms in 53 developing countries shows that women’s employment among private firms is significantly higher in countries that mandate paternity leave versus those that do not. A conservative estimate suggests an increase of 6.8 percentage points in the proportion of women workers associated with mandating paternity leave. The empirical specification is immune to spurious correlations that affect the level of women and men employment equally and also robust to a large number of controls for country and firm characteristics. 相似文献

Several different approaches to international comparison of Total Factor Productivity (TFP) have now emerged. Among these are the time-series approach, the panel approach, and the cross-section approach. This paper compares methodologies of these different approaches and results that have been obtained from their application. The comparison of results is conducted in the context of two samples, namely the sample of G7 countries and a large sample that includes developing nations. It is found that while there are broad agreements in results, there exist considerable differences too. The analysis shows how these differences can be related, in part, to differences in methodology. The paper also shows how these different approaches to international TFP-comparison can play a complementary role in enhancing our understanding of such important phenomena as technological diffusion and TFP-convergence. 相似文献

We review the measurement of product attribute importance, and find little consensus in definition or measurement methods. We compare four measurement methods: 1) two direct methods whereby respondents report the importance of attributes using best–worst scaling or constant sum scales, and 2) two indirect methods derived from discrete choice experiments. Our comparisons rely on previous findings that choice experiments are externally valid to use as the standard. We find high agreement within direct or indirect methods, but less agreement between direct and indirect methods. Our results also demonstrate that inferences derived from indirect measures appear to be susceptible to context effects related to the particular attributes a researcher chooses to investigate. We discuss implications for current and future research. 相似文献

Disclosures of Social Value Creation and Managing Legitimacy: A Case Study of Three Global Social Enterprises 下载免费PDF全文
Muhammad Azizul Islam 《Australian Accounting Review》2017,27(3):297-314
This study seeks to fill the gap in the existing literature by examining how and whether disclosure of social value creation becomes a part of the legitimation strategies of social enterprises. In particular, using Suchman's (1995) moral dimension of legitimacy theory, this study sets out whether and how disclosures by three global social organisations – Grameen Bank, Charity Water and the Bill & Melinda Gates Foundation – conform to the expectations of the broader community. The study finds that there is an apparent disconnection between disclosure and action by social enterprises. With reference to a few incidents, social enterprises use disclosure as a part of their managerial efforts, rather than to create moral legitimacy. The notion of apparent disconnection between disclosure and real action by social enterprises is evident. The notion is consistent with extant disclosure literature capturing the motivations for the disclosure practices of corporations. The findings of this paper suggest that when an organisation (whether it is a corporation or a social enterprise) faces a legitimacy crisis, it appears to disclose good news rather than bad news, which calls into question organisational moral legitimacy. 相似文献

Entrepreneurship researchers have documented that early stage startups rely on signals to demonstrate the transitions in their identities that they must make when they cross organizational life cycle thresholds. However, early stage startups in emerging industry contexts tend to have few good signals upon which to rely. Public agencies can play a valuable role in this process, but prior research has not sufficiently examined how startups effectively leverage this support. In this paper, therefore, we develop a framework to investigate the role that signals can play for early stage startups when they win prestigious government research grants. We test this framework in the setting of the emerging U.S. clean energy sector and find that in comparison to a matched sample of clean energy startups that have not won prestigious research grants, startups with these grants were 12% more likely to acquire subsequent venture capital (VC) funding. Another significant result is that the value of this signaling is greater for startups that have fewer patents. The important contribution of this finding is that it shows that signaling has the potential to redistribute benefits rather than just provide an additional accrual of advantages to the already high status actors. Together these results highlight the advantages for startups in emerging industries of pursuing signaling strategies with public agencies when they attempt to make important transitions through the stages of their organizational life cycles.
