Blockchain in Additive Manufacturing and its Impact on Supply Chains

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.     

Pensions and poverty traps: Is saving worthwhile for women?

Present policy means that a private pension, unless it is substantial, may fail to bring financial gain in retirement due to means testing: the pensions poverty trap. This paper examines women's acquisition of private (occupational and personal) pensions and their risk of facing this trap. Because of the loosening link between marriage and motherhood, previous patterns of pension advantage according to marital status are shifting. The employment and pension impact of motherhood varies with socio-economic status but the pension prospects of the majority of women are poor. It is concluded that women's need for financial advice to avoid the pensions poverty trap is greater than men's. An improved basic pension, indexed to national income, would reduce the risk of mis-selling and restore confidence that saving for a pension is worthwhile.     

Debt relief for Eastern Europe — Its costs and the distribution of proceeds: Some preliminary results

Zusammenfassung Schuldenerla? für Osteuropa - Kosten und Verteilung der Ertr?ge. Einige vorl?ufige Ergebnisse. - Zweck dieses Aufsatzes ist es, die Kosten zu sch?tzen, die von einer internationalen Finanzinstitution im Falle eines Schuldenerlasses für Osteuropa getragen werden mü?ten. Da derartigen Kosten, die letzten Endes von den ?ffentlichen Haushalten der Gl?ubigerstaaten zu tragen w?ren, Ertr?ge gegenüberstehen, die mit einem solchen Schuldenerla? verbunden sind, ist es auch m?glich, die Verteilung dieser Ertr?ge unter den Begünstigten zu untersuchen. Zu diesem Zweck entwickelt und diskutiert der Autor ein einfaches Modell eines Schulden-Rückkaufs. Darin werden sowohl die Kosten gesch?tzt, die mit einem solchen Rückkauf zugunsten Osteuropas verbunden sind, als auch die voraussichtliche Verteilung der Ertr?ge.

Résumé Remise de la dette des pays en Europe de l’Est - Les co?ts et la distribution des bénéfices: Quelques résultats préliminaires. - L’objet de cette étude, c’est l’estimation des co?ts qui devraient être payés par une institution internationale au cas d’une remise de la dette en faveur de l’Europe de l’Est. Comme ces co?ts, qui devraient être payés par les budgets publics des états créanciers en fin de compte, se sont accompagnés par des bénéfices, il est aussi possible d'examiner la distribution de ces bénéfices entre les bénéficiaires. Par conséquence, l’auteur de cette étude développe et discute un modèle simple pour analyser les effets d’un rachat des dettes. Il estime tous les deux facteurs, le montant des co?ts impliqué par un tel rachat des dettes en faveur de l’Europe de l’Est et aussi la distribution probable des bénéfices.

Resumen La reducción de la deuda externa de Europa Oriental. Sus costos y la distribución de sus beneficios: algunos resultados preliminares. - El objeto de este trabajo es estimar el costo que podría ser asumido por una institucíon internacional en caso de una reducción de la deuda externa de Europa Oriental. Debido a que estos costos, que en última instancia podrian ser asumidos por los presupuestos públicos de los países acreedores, son compensados por los beneficios que la reducción aporta a los participantes, también es posible examinar la distribución de los beneficios. Por ello, el trabajo desarrolla y discute un modelo simple de compra de deuda por parte de los países deudores mismos. Se estiman los costos de una compra de deuda a favor de Europa Oriental y la posible distribución de los beneficios.

     

Growth, Inequality, and Well-Being: Intertemporal and Global Comparisons

We use several well-being measures that combine average incomewith a measure of inequality to undertake intertemporal andglobal comparisons of wellbeing. The conclusions emerging fromthe intertemporal analysis are that the impact of these measureson temporal trends in well-being is relatively small on average,but changing across the decades. In particular, it suggeststhat changes in well-being were understated in the 1960s and1970s and overstated in the 1980s and 1990s. Our global analysiscovering ca. 81 per cent of the world's population demonstratesthat global well-being is at least 50 per cent smaller thanworld per capita income if the unequal income distribution isalso factored in. Conversely, growth in world well-being hasbeen larger than world income growth between 1970–1998.Since the inclusion of inequality has an important impact onwell-being comparisons, it is of great importance to generatemore consistent and intertemporally as well as internationallycomparable data on inequality.

Learning, Asset-Pricing Tests, and Market Efficiency

This paper studies the asset-pricing implications of parameter uncertainty. We show that, when investors must learn about expected cash flows, empirical tests can find patterns in the data that differ from those perceived by rational investors. Returns might appear predictable to an econometrician, or appear to deviate from the Capital Asset Pricing Model, but investors can neither perceive nor exploit this predictability. Returns may also appear excessively volatile even though prices react efficiently to cash-flow news. We conclude that parameter uncertainty can be important for characterizing and testing market efficiency.     

Alliance competence, resources, and alliance success: Conceptualization, measurement, and initial test

This research examines the effect of an alliance competence on resource-based alliance success. The fundamental thesis guiding this research is that an alliance competence contributes to alliance success, both directly and through the acquisition and creation of resources. Using survey data gathered from 145 alliances, empirical tests of the hypotheses provide support for the posited explanation of alliance success. The findings indicate that an alliance competence is not only antecedent to the resources that are necessary for alliance success but also to alliance success itself. C.
