The digital age offers unprecedented opportunities for firms to access new knowledge for innovation. Both academics and managers have identified crowdsourcing (CS) as one relevant way to do so. CS for innovation involves outsourcing problem-solving or creative tasks to the crowd. To benefit from CS, absorptive capacity (ACAP) is critical; this can be enhanced by prior knowledge and past experience with a partner. However, in the CS context, firms open themselves up to undefined, anonymous partners through the Internet, hence the development of ACAP becomes more difficult. The literature on ACAP describes how internal integration mechanisms encourage the absorption of knowledge but fails to clearly address the way in which uncommon knowledge is integrated. Although literature has acknowledged the beneficial role of a wider spectrum of influential internal and external mechanisms on uncommon knowledge, few empirical studies have addressed the distinctive effect of these mechanisms on the absorption of anonymous partners’ knowledge. To fill this gap, this study identifies relevant integration mechanisms and how they impact upon different ACAP dimensions in the CS context. Five case studies reveal the distinctive influence of integration mechanisms depending on the nature of the CS activity. Our results extend research on ACAP in the little studied digital open context, investigating the absorption of uncommon knowledge from unidentified partners. From a managerial perspective, this study shows that managers need to pay attention to integration mechanisms in order to support the absorption of knowledge from the crowd. More precisely, our study suggests that the main focus should not be on external mechanisms, but also on internal mechanisms. Finally, we open up a new theoretical debate on how these mechanisms should be combined. 相似文献

El artículo examina la viabilidad del sindicalismo para ciertos trabajadores migrantes del cuidado. Primero revisa las concepciones básicas de la acción sindical y después, apoyándose en un análisis detallado de una campaña reciente de sindicación de cuidadores migrantes en Israel, demuestra la aportación única del enfoque sindical frente al de otras asociaciones cívicas que apoyan a estos trabajadores: a pesar de los muchos problemas que entraña su sindicación, en razón de la naturaleza de su trabajo y de obstáculos jurídicos e institucionales, el sindicalismo es la única vía para dotar a los trabajadores migrantes de ciudadanía laboral y de agencia política. 相似文献

In the current article, it is argued that individual differences in imaginative thinking may predict transformational leadership. Transformational leaders create a vision for the future, which they must imagine. Moreover, being able to imagine differences in thinking and behavior may aid in the development of more transformation leaders via guided reflection on their leadership practices. Ultimately, assessment of individual differences in imaginative thinking may be useful in recruitment of leaders. 相似文献

In recent decades, many “Making Work Pay” policies have been implemented in OECD countries. These policies aim at improving
the financial incentives for work, while maintaining high levels of social protection. Examples include the Earned Income
Tax Credit in the USA and the Working Families’ Tax Credit in the UK. While these policies are proven to be quite effective
with respect to poverty alleviation, many worry that they may discourage labor supply on the intensive margin. We consider
an alternative measure implemented in Belgium: the Workbonus, which subsidizes social security contributions for low-skilled
workers. This program differs from other measures in that the eligibility and the level of the subsidy are based on full-time
equivalent earnings. The instrument therefore distinguishes between low skill and low effort and avoids the above-mentioned
disincentive effect. We assess the effects of the Workbonus on labor supply using a particular discrete-choice labor supply
model, in which individuals are assumed to choose among jobs belonging to individual-specific latent choice sets. In particular,
we compare the Workbonus with a tax credit system temporarily implemented in Belgium in 2001–2004. Results show that both
measures have a positive impact on labor supply. However, the Workbonus is more efficient in terms of cost per additional
full-time equivalent position created and avoids the “part-time trap” implicit in the tax credit system. 相似文献

Farming system modelling for agri-environmental policy design: The case of a spatially non-aggregated allocation of conservation measures 总被引:2,自引:0,他引:2

This paper addresses the issue of designing policies for habitat conservation on agricultural land. The case under study requires a non-aggregated spatial distribution of the fields to be enrolled in an agri-environmental programme. A spatially explicit mathematical programming farm-based model, which accounts for three spatial levels (field, farm and landscape), is coupled with a relevant spatial pattern index (the Ripley L-function) to analyse the design and implementation of an agri-environmental programme aimed to preserve the Tetrax tetrax in the Plaine de Niort, France. The model is run using a stylised map with heterogeneous soil types and both crop growing and mixed dairy farms. Results show that valuable insights into agri-environmental programme design are gained through a detailed representation of farming system management. The suitable, non-aggregated spatial pattern for T. tetrax conservation is more costly than less-suitable, more aggregated patterns, because it tends to require equal participation of all farms. The policy simulations reveal that the various spatial patterns can be obtained through relatively simple uniform contract structures. An effective contract structure entails a set of two degressive payments which encourages all farms to enrol at least a small share of their land in the program. 相似文献
