Can new channels for mid-skill labour mobility simultaneously enhance the welfare of Australia and the Pacific Region? Answering this question requires forecasting Australian demand for vocationally-skilled migrants over the next generation, and the potential for Pacific supply of those migrants. We project demand for such mid-skill migrants over the next three decades by combining data on trends in the demand for basic tasks with data on trends in native investment in education commensurate with those tasks. We estimate that the Australian economy growing at historical rates through the year 2050 will demand approximately 1.6–2.1 million foreign workers with Technical and Vocational Education and Training. A large share of these could be supplied from the Pacific Islands with sufficient investment in training, with direct cooperation from Australian employers, and targeted access to the Australian labour market.  相似文献

Das Controllability-Prinzip fordert, Akteure nur für das verantwortlich zu machen, was diese auch beeinflussen k?nnen. In empirischen Studien wird jedoch berichtet, dass Unternehmen h?ufig gegen dieses Postulat versto?en und dass somit das Postulat m?glicherweise für Unternehmen nicht relevant ist. Dabei rekurrieren die meisten Studien nicht direkt auf das Postulat, sondern auf davon abgeleitete Handlungsmaximen. Vor diesem Hintergrund konsolidiert der vorliegende Review von 29 empirischen Studien die vielf?ltigen und scheinbar widersprüchlichen Detailerkenntnisse zum Controllability-Prinzip. Es wird deutlich, dass der Versto? gegen eine der Handlungsmaximen nicht mit einem Versto? gegen das Controllability-Prinzip gleichgesetzt werden darf. Das Postulat k?nnte somit sehr wohl für Unternehmen relevant sein. Zum anderen konnte gezeigt werden, dass die Wahrnehmung von Beeinflussbarkeit, Verantwortung und damit die Einhaltung des Prinzips sowohl von individuellen Pers?nlichkeitsmerkmalen als auch von Eigenschaften des Unternehmens (des korporativen Akteurs) abh?ngig ist. Es wird damit auch deutlich, dass erst eine Studie, die sowohl individuelle Pers?nlichkeitsmerkmale als auch Eigenschaften des Unternehmens berücksichtigt, geeignet ist, Aussagen zur Relevanz des Controllability-Prinzips zu liefern.  相似文献

This paper develops a recursive dynamic computable general equilibrium (DCGE) model to evaluate sources of accelerated growth and structural transformation. It goes beyond stylized and aggregate general equilibrium models by examining country-specific growth options to reach middle income country (MIC) status. We first examine a set of countries that have successfully transformed their economies to inform model and scenario building. We then simulate potentials and trade-offs of selected sector- and factor-specific growth paths for Ghana. Results show that no individual sector's growth acceleration is sufficient for Ghana to reach MIC status by 2015. Manufacturing growth is constrained by its high dependency on agricultural inputs indicating the need for diversification. Services can support rather than drive economy-wide growth. Agriculture must remain the mainstay of economy-wide growth. While this will delay structural change in sectoral composition, it demonstrates that emphasizing agriculture is a viable option for some countries to reach MIC status.  相似文献

We show that optimal partisan redistricting with geographical constraints is a computationally intractable (NP-complete) problem. In particular, even when voter's preferences are deterministic, a solution is generally not obtained by concentrating opponent's supporters in “unwinnable” districts (“packing”) and spreading one's own supporters evenly among the other districts in order to produce many slight marginal wins (“cracking”).  相似文献

The fundamental paradigm shift from traditional value chains to agile service value networks implies new economic and organizational challenges. As coordination mechanisms, auctions have proven to perform quite well in situations where intangible and heterogeneous goods are traded. Nevertheless, traditional approaches in the area of multidimensional combinatorial auctions are not quite suitable to enable the trade of composite services. A flawless service execution and therefore the requester’s valuation highly depends on the accurate sequence of the functional parts of the composition, meaning that in contrary to service bundles, composite services only generate value through a valid order of their components. The authors present an abstract model as a formalization of service value networks. The model comprehends a graph-based mechanism implementation to allocate multidimensional service offers within the network, to impose penalties for non-performance and to determine prices for complex services. The mechanism and the bidding language support various types of QoS attributes and their (semantic) aggregation. It is analytically shown that this variant is incentive compatible with respect to all dimensions of the service offer (quality and price). Based on these results, the authors numerically analyze strategic behavior of participating service providers regarding possible collusion strategies.  相似文献

In many OECD countries, statutory corporate tax rates are lower than personal income tax rates. This tax rate difference is often particularly large for small firms. The present paper argues that a reduction of the corporate tax rate below the personal tax rate is an optimal tax policy if there are problems of asymmetric information between investors and firms in the capital market. The reduction of the corporate tax rate below the personal tax rate encourages equity financing and thus mitigates the excessive use of debt financing induced by asymmetric information. Our main theoretical result stands in marked contrast to the traditional view of corporate taxation and corporate finance theory, according to which there is a tax disadvantage to equity financing. More recent empirical evidence on this issue, however, is in line with our result.  相似文献

The regional green power labeling according to the EEG 2017 represents an extension of the possibilities for labeling green electricity. In this paper we investigate the extent to which the implementation of regional green power products using the green power labeling regime under the EEG 2017 can help to strengthen the regional brand core of German power marketers, and which is the best alternative for raising the regional brand core of these firms. To this end, the different options for green power marketing with regional reference are discussed in detail, and it is elaborated which additional marketing models are enabled through the regional green power labeling. Furthermore, the criteria are identified with which the various green power labeling models with regional reference—with respect to their potential to raise the regional brand core—ought to be compared with each other. The results from our analysis show that the regional green power labeling based on EEG 2017 can be used to systematically upgrade the options for the marketing of regionally generated electricity already in place before the EEG 2017 entered into force.  相似文献

The main purpose of this paper is to address the issue of robustness of stock option plans, which is essential for reliable accounting valuations. The introduction of the accounting standards SFAS 123R and IFRS 2 for executive stock options has led to an important change. As companies are now forced to value their stock options at grant date for accounting purposes, the robustness of prices against the choice of certain valuation models and input parameters has become a very important issue. We address this issue by first analyzing certain building blocks of existing stock option plans with regard to their robustness properties. Based on our analysis, we then show how robustness of stock option plans can be achieved. The resulting stock option plans are both transparent in structure and reasonable in respect to the incentives they provide in order to increase shareholder value. We therefore conclude that stock options can be reliably expensed, if the corresponding plans are properly designed.  相似文献
