Country of origin labeling for complex supply chains: the case for labeling the location of different supply chain links

We investigate the value of a country of origin label (COOL) that separately identifies the geographic location of different stages in a food product's supply chain. We estimate the willingness‐to‐pay (WTP) of U.S. consumers for a packaged cereal product where the key grain ingredient may be grown in one country and processed in a second country (multicountry supply chain) and compare it to equivalent products that have both stages located in a single country. We find consumer WTP for products with single‐country and multicountry supply chains are statistically different, meaning that simplifying a multicountry label by listing only the country where the ingredients are grown or only the country where the ingredients are processed can result in different consumer values. We also find that for countries with a poor quality reputation, consumers respond more negatively when that country has the “last touch” than when that country's involvement is limited to upstream supply chain links.     

Quota prices as indicators of comparative advantage in supply‐managed industries

The Canadian dairy, egg, broiler, and turkey industries operate under supply management, a policy regime that sets product prices and allocates production among provinces and ultimately among farms through quotas. The Canadian Farm Products Agencies Act requires that comparative advantage be used to guide the allocation of new quota when increases in consumer demand necessitate increased production. This requirement, however, has not been met in practice. We develop a proposal by Meilke to use quota prices as measures of comparative advantage. We evaluate the quota price approach and other proposed methods, from a Hayekian and Coasean market process perspective. We conclude that quota prices offer an economically justifiable indicator of provincial comparative advantage. We develop an individual‐level general equilibrium model of quota exchange to illustrate the informational content of quota prices as indicators of comparative advantage. We also discuss potential practical challenges of using quota prices as indicators of comparative advantage.     

The effects of capacity reduction policy under the interest rate peg in China

Capacity reduction has been a recurrent theme in China's economic policy. The central government takes various administrative measures to remove excess capacity, accumulated mainly due to underpriced production factors and distorted incentives. I evaluate the de-capacity policy in a series of models and prove that its effects depend critically on its persistence and monetary policy regime. Under an interest rate peg, a transient policy that changes markup temporarily is ineffective and even expansionary, whereas a persistent policy is effective due to a negative wealth effect. A permanent de-capacity policy can lead to over-reactions in macro variables because the interest rate peg adds positive feedback to the economy. Therefore, the de-capacity policy has greater uncertainty under the interest rate peg. As a policy tool, it easily deviates from its target and brings about excessive volatility. However, long-run price stability and a gradually advanced de-capacity policy are conducive to the achievement of policy targets.     

Information,market power,and price volatility

We consider demand function competition with a finite number of agents and private information. We show that any degree of market power can arise in the unique equilibrium under an information structure that is arbitrarily close to complete information. Regardless of the number of agents and the correlation of payoff shocks, market power may be arbitrarily close to zero (the competitive outcome) or arbitrarily large (so there is no trade). By contrast, price volatility is always lower than the variance of the aggregate shock across all information structures. Alternative trading mechanisms lead to very distinct bounds as a comparison with Cournot competition establishes.     

Outsourcing the procurement function: Do actions and results align with theory?

Are common theories of outsourcing useful in predicting the extent of and performance gains from the outsourcing of procurement activities? Or does procurement׳s broad scope and boundary-spanning role confound successful analysis? This study applies a theoretical framework combining concepts from transaction-cost economics (TCE) and the resource-based view (RBV) to study the procurement outsourcing decisions of two hundred and eighty US-based electronics manufacturing firms. Findings suggest that TCE and RBV act in complementary ways on the procurement outsourcing decision. TCE, through fear of supplier opportunism, appears to be the primary driver of the extent to which procurement activities are outsourced. The RBV, through which the OEM׳s resource position in procurement vis-à-vis its outsourcing partner is determined, appears to be the primary determinant of the performance results of the outsourcing decision. Procurement activities are outsourced to a greater extent when fear of supplier opportunism is low, but such outsourcing is only “justified” (expected to yield performance benefits) when the OEM has a weak resource position vis-à-vis the outsourcing partner. An “enriched” TCE–RBV framework is presented and discussed as part of study results.     

The relationship between legitimacy,reputation, sustainability and branding for companies and their supply chains

This paper aims at filling a gap that we perceive to exist in the scientific literature as to legitimacy, reputation and sustainability and their interrelationship to corporate and supply chain branding. A series of innovative theoretical frameworks are provided interrelating companies and their value (supply) chains with legitimacy, reputation, and branding which are essential conditions to achieve sustainability and competitive advantage based on dyadic and social context consonance to the benefit of society and all stakeholders involved. An urgently required better understanding of the concepts and their interrelations is enhanced by a synthesized explanatory basis entailing an eclectic mosaic of interdisciplinary theories (institutionalist, neo-institutionalist theories, the viable system approach, isomorphism and identity) to improve corporate and supply chain performance. To better inform managerial practice the theoretical considerations are spiced with case studies among which especially the currently debated supply chain case of the European horse meat scandal is illuminated suggesting concrete managerial cross-functional implications in the food industry. The paper culminates in the call for a newly to-be-established marketing stream we call ‘Sustainable and Curative Marketing’.     

基于人力资本价值链理论的中国城市国际人才集聚研究

城市国际人才争夺战由来已久并不断升级，但针对中国城市国际人才集聚水平、影响因素和差异化政策供给的研究鲜见。以“国际人才集聚指数-国际人才集聚影响因素-国际人才集聚政策”为研究主线，以中国36个主要城市为研究对象，创新性地通过构建人力资本“投入-过程-产出”价值链理论模型进行实证研究，结果表明：中国城市国际人才集聚指数排名分为3个差异显著的层级。其中，第二和第三层级之间无较大差距，但与由北京、上海组成的第一层级相比大幅落后。中国城市国际人才集聚影响因素分化明显，第一类城市的主要影响因素为全球城市品牌文化；第二类城市为创新型经济发展；第三类为外资传统工商业企业和产业集聚。对应地，中国城市国际人才集聚政策供给围绕外资传统工商业国际人才集聚、高端生产性服务业国际人才集聚、多样性和包容性国际人才文化氛围营造存在三大差异化选择。首次构建人力资本“投入-过程-产出”价值链模型，为从机理上深入探索中国各类城市国际人才集聚模式及提升路径奠定了基础。     

Resale price maintenance for supply chains distributing products with demand uncertainty

This paper explores the economic roles of resale price maintenance (RPM) in supply chains for a specific product, when consumers have taste heterogeneity and the manufacturer faces demand uncertainty. Two transaction schemes within supply chains are compared: (1) RPM, and (2) decentralized pricing in a competitive market environment. With decentralized pricing, a manufacturer loses the incentive to produce a product in categories where the probability that the manufacturer fails to design the product as suitable to public tastes of consumers is high. However, RPM resolves the problem and induces the manufacturer to supply the good, bringing positive surplus to consumers.     

Design and planning for green global supply chains under periodic review replenishment policies

We quantify the impact of jointly optimizing strategic network design and tactical inventory planning on the cost and CO₂ emissions of multi-echelon logistics networks. The obtained insights indicate that longer optimized replenishment cycles reduce a node’s transportation cost and CO₂ emissions but increase its inventory costs. Moreover, under a fixed replenishment cycle, a node’s service level increases when supplied by a satellite warehouse. Finally: (i) the costs of implementing optimal green network design decisions could be misleading if inventory planning is neglected, (ii) greening of supply chains could become expensive, (iii) current legislative CO₂ ton prices hardly influence logistics networks.
