This article sounds the alarm that a significant build-out of efficient lighting and renewable energy technologies may be endangered by shortages of rare earths and rare earth permanent magnets. At the moment, China is the predominant supplier of both and its recent rare earth industrial...

A bullwhip measure for a two-stage supply chain with an order-up-to inventory policy is derived for a general, stationary SARMA(p, q) × (P, Q)s demand process. Explicit expressions for several SARMA models are obtained to illustrate the key relationship between lead-time and seasonal lag. It is...

This paper explores the relation between supply-chain participation and the internationalization of firms. We show that even small and less productive firms, if involved in production chains, can take advantage of reduced costs of entry and economies of scale that enhance their probability of...

In this study, we apply the inter-regional input–output model to explain the relationship between China’s inter-regional spillover of CO2 emissions and domestic supply chains for 2002 and 2007. Based on this model, we propose alternative indicators such as the trade in CO2...

Over the past five years, global retail chains such as Walmart, McDonald’s and Starbucks have accelerated their efforts to source and sell coffee ‘sustainably’. Whereas ethical and environmental concerns were the intended drivers of fair trade and organic coffee uptake among...

The average propagation length (APL) has been proposed as a measure of the fragmentation and sophistication of an economy. For a one-sector economy, we show that the APL is strictly proportional to the macro multiplier of that economy. The same holds for strong intra-industry linkages. Hence,...

Derrière une idée apparemment simple et séduisante, les kilomètres alimentaires sont au centre de questions complexes aux enjeux multiples. Nous mettons en évidence qu’au delà des promesses, les difficultés liées à l’opérationnalisation d’un tel concept sont considérables et...

Extensive research has demonstrated the existence of large potential welfare gains from trade facilitation—measures to reduce the overall costs of the international movement of goods. From an equity perspective an important question is how those benefits are distributed across and within...

The emergence and spread of drug resistance is draining available resources and threatening our ability to treat infectious diseases in developing countries. HIV/AIDS, tuberculosis, malaria, diarrhea, and respiratory tract infections continue to be the leading causes of death in many developing...
