Additive manufacturing (AM) appears to be a particularly attractive use case for blockchain. This research combines inductive in‐depth interviews with the Delphi method to explore what potentials blockchain technology in AM creates, which adoption barriers firms need to overcome, and how supply chains will be affected by the integration of these two potentially disruptive technologies. The results suggest opportunities that are related to intellectual property (IP) rights management, the monitoring of printed parts throughout their lifecycle, process improvements, and data security. The most important barriers for blockchain adoption in AM are an absence of blockchain‐skilled specialists on the labor market, missing governance mechanisms, and a lack of firm‐internal technical expertise. By addressing important limitations of AM, blockchain is expected to improve the competitiveness of AM in parts’ production, catalyzing the trend toward more decentralized manufacturing resulting in more agile, resilient, and flexible supply chains and reduced logistics costs. Beyond that, blockchain‐based AM platforms are expected to enhance supply chain visibility, drive supply chain digitalization, support supply chain finance, and contribute to the emergence of shared factory systems. 相似文献

We develop a political-economy model where the amount of education subsidies is determined in a majority vote and spending is financed by revenues from taxation. Our analysis demonstrates that limiting the extent of subsidization and thus excluding the poor from gaining enough education can be a political equilibrium. Despite being the main beneficiaries of subsidies, the politically decisive middle class hesitates to extend monetary benefits, since improved access to higher education diminishes the return to education. Moreover, a non-monotone relation between inequality and the extent of redistribution through tax-financed educational subsidies obtains. 相似文献

Analytical expressions for the unconditional state-covariance matrix are combined with an efficient scheme for computing theoretical autocovariances, to simplify the exact maximum-likelihood estimation of multivariate ARMA models. Alternative state-space representations for pure AR and pure MA processes, giving rise to straightforward expressions for their unconditional state covariance, are suggested. 相似文献

The English (Association) Football League is a long established industrial cartel selling a highly popular product with only imperfect substitutes. Despite that, the majority of its member clubs lose money and the industry has faced successive financial crises over the last decade. This paper develops an empirical model of the financial performance of English League clubs using a high quality dataset of 48 clubs over the period 1974–89. The underlying model explains how rents are competed away through the maximising behaviour of club owners subject to production constraints. This model is parameterised by a system of equations which describe the behaviour of a maximising owner subject to demand and production constraints. The model is then used to examine the coordination failure which lies at the heart of the English Football League's decline and to assess the prospects for the Premier League. 相似文献

European Union banana policies do not make economic sense, and hence criticism of these policies is justified. Some facts should, though, be remembered. If the EU had chosen free trade in bananas when the Single Market was established, certain producers both inside and outside the EU would have lost income, and it proved politically impossible to choose direct financial compensation. Also, the quantitative implications of the new EU banana regime may be less than sometimes assumed, as trade has not been reduced very much. The WTO's role is not to judge the economic merits of these policies, but their legal justification. 相似文献
