Staking Cosmopolitan Claims: How Firms and NGOs Talk About Supply Chain Responsibility

Non-governmental organizations (NGOs) increasingly hold firms responsible for harm caused in their supply chains. In this paper, we explore how firms and NGOs talk about cosmopolitan claims regarding supply chain responsibility (SCR). We investigate the language used by Apple and a group of Chinese NGOs as well as Adidas and the international NGO Greenpeace about the firms’ environmental responsibilities in their supply chains. We apply electronic text analytic methods to firm and NGO reports totaling over 155,000 words. We identify different conceptualizations of cosmopolitanism in this discourse: a legalistic approach to cosmopolitanism for Apple and a group of Chinese NGOs and a moralistic approach for Adidas and Greenpeace. We argue that these differences connect to the roles that the firms are expected and perhaps willing to take in SCR: legalistic discourse connects to a governmental function of rule development and enforcement; in contrast, moralistic discourse connects to a citizenship function that focuses on doing good to the global community. We discuss implications for companies’ non-market strategies and future research.     

Brexit: How Will UK Agriculture Fare?

There is little doubt that Brexit would have significant implications for UK agriculture, a sector with strong trade links to the EU and strong reliance on CAP income support. This article reports preliminary results from employing a Computable General Equilibrium Model, a Partial Equilibrium Model and Farm Level Models to explore selected trade and domestic policy scenarios post‐Brexit. These allow for the estimation of changes in producer prices, production and farm incomes against a baseline scenario of continued EU membership. Under a Free Trade Agreement with the EU, agricultural impacts are relatively modest. By contrast, unilateral removal of import tariffs has significant negative impacts on prices, production and incomes. Adoption of the EU's WTO tariff schedule for all imports favours net importers (e.g. dairy) and harms net exporters (e.g. sheep). Given the strong dependence of most UK farms on direct payments, their removal worsens negative impacts of new trade arrangements and offsets positive impacts. Impacts vary across different types and sizes of farm, but also regionally. However, the period of adjustment to new trade and domestic policy conditions may prove very challenging for a large number of farm businesses.     

The Buyer–Supplier Relationship: An Integrative Model of Ethics and Trust

Dialogues between companies and actors of society often start as a result of a public scandal or in a situation of crisis. They can lead to short-term public relations activism or to long-term reputation gains. On the basis of cases and of a typology of forms of dialogues, the author develops ethical criteria and conditions for a successful dialogue – the ethical basis for such criteria being values such as equality, freedom and participation. A special focus is put on challenges that often result from dialogues such as the ethical judgment of compromises. This article proposes ethical criteria to evaluate compromises. This leads to a model of ethical dialogue.     

ARBITRAGE BOUNDS FOR PRICES OF WEIGHTED VARIANCE SWAPS

We develop a theory of robust pricing and hedging of a weighted variance swap given market prices for a finite number of co‐maturing put options. We assume the put option prices do not admit arbitrage and deduce no‐arbitrage bounds on the weighted variance swap along with super‐ and sub‐replicating strategies that enforce them. We find that market quotes for variance swaps are surprisingly close to the model‐free lower bounds we determine. We solve the problem by transforming it into an analogous question for a European option with a convex payoff. The lower bound becomes a problem in semi‐infinite linear programming which we solve in detail. The upper bound is explicit. We work in a model‐independent and probability‐free setup. In particular, we use and extend Föllmer's pathwise stochastic calculus. Appropriate notions of arbitrage and admissibility are introduced. This allows us to establish the usual hedging relation between the variance swap and the “log contract” and similar connections for weighted variance swaps. Our results take the form of a FTAP: we show that the absence of (weak) arbitrage is equivalent to the existence of a classical model which reproduces the observed prices via risk‐neutral expectations of discounted payoffs.     

入美企业如何避开国家安全限制

2008年11月14日,美国财政部发布《2007年外国投资与国家安全法》（FINSA）的实施细则,此项法律旨在改革美国外国投资委员会（CFIUS）关于国外机构收购、兼并和接管美国企业国家安全审查体制。2008年12月,美国财政部发布了有关经过CFIUS审核认为存在国 家安全问题的交易类别指引，正式条例和相关指引传递的明确信息是，在个案基础上，CFIUS将保持其对外国投资交易进行国家安全审查的广泛自由裁量权。那么，美国这些法规的出台将会给我国企业以外资并购的方式进入美国市场带来怎样的影响？     

Multiple Buyers, Rent‐Defending and the Observed Social Costs of Monopoly

This paper uses analytical and experimental methods to assess the effects of fracturing the interests of agents seeking to maintain the competitive status quo in a rent‐seeking contest for a monopoly franchise. Theoretically, it is shown that while "rent‐defending" can ameliorate the social costs of rent‐seeking, these beneficial effects deteriorate quickly as the interests of those seeking to maintain the status quo become fractured. Experimental results indicate that overbidding is persistent when bidders have different sharing rules. In fact, the observed social costs of rent‐seeking often increase just when rent‐defending has the greatest predicted ameliorative effect.
