Exclusivity and Control

We model competition between content distributors (platforms) for content providers, and show that whether or not content is exclusive or “multihomes” depends crucially on whether or not content providers maintain control over their own pricing to consumers: if content providers sell their content outright and relinquish control, they will tend to be exclusive; on the other hand, if content providers maintain control and only “affiliate” with platforms, then multihoming is sustainable in equilibrium. We show that the outcome under affiliation depends on the tradeoff between platform rent extraction (which increases in exclusivity) and content rent extraction (which increases in multihoming), and demonstrate that the propensity for exclusivity can be increasing, decreasing, or even nonmonotonic in content quality. Finally, if a content provider internalizes the effect of its own price on platform demand, we prove that a platform that already has exclusive access to content may prefer to relinquish control over content pricing to the content provider in order to reduce price competition at the platform level.

Real exchange rates,asset prices and terms of trade: A theoretical analysis

This paper develops a continuous-time two-country dynamic equilibrium model, in which the real exchange rates, asset prices, and terms of trade are jointly determined in the presence of nontradable goods. The model determines the relation between the financial markets and real goods markets in the world economy and their responses to various shocks under the home bias assumption. A positive domestic supply shock induces a positive return on the domestic asset markets and a deterioration of terms of trade that improves the foreign output and boosts the foreign asset markets. Demand shocks act in the opposite way. This model also analyses the impact of change in the relative price of nontradable to tradable goods on the terms of trade and asset markets. A higher productivity growth in tradable goods than in nontradable goods leads to a higher relative price of nontradable to tradable goods, which appreciates the real exchange rate, deteriorates the terms of trade, and depresses the domestic and foreign asset markets. A lower relative price of nontradable goods depreciates the real exchange rate, improves the terms of trade, and lifts both the domestic and foreign asset markets.     

支付制度、医生的行为与药物经济学的应用

制度影响人们的行为选择,引发不同的效率结果。在医疗卫生市场中,不同的支付制度加上一些其他经济因素,使得追求收益最大化的医生具有不同的目标收益函数和行为选择。这些行为选择对社会而言可能具有效率,也可能无效率。通过比较不同支付制度下医生的行为选择及其是否符合效率准则,我们能够发现对药物经济学应用有利的一些制度因素。     

社会审计委托代理分析

本文分析了社会审计契约中委托代理关系及审计信息不对称表现及形成原因,通过建立社会审计的委托代理模型,揭示了在审计人和委托人均完全理性的假设下,委托人可以通过激励机制鼓励审计人尽最大努力完成工作。在此基础上分析了我国社会审计收费制度的不合理性、转轨经济环境下社会审计合约具有的不完全契约特性,并提出了改革的设想。     

Economic Justice: Confronting Dilemmas

Abstract:

This article uses a simple economic model to study important issues in debates about distributive justice. What role do non-labor productive assets play? What role does private ownership play? What role does scarcity play? What role do credit and labor markets play? The model is used to address these questions, and in the process explain why even if those who acquire scarce productive assets do so fairly, and in a manner that deserves compensation, there is reason to believe (1) that when people own productive assets privately outcomes will become unfair, and (2) credit and labor markets will aggravate inequities. The article concludes that distributive justice requires compensation commensurate with the economic sacrifices people make and acknowledges important challenges that must be overcome to achieve this.

How to rescue a failing pension regime: the British case

Recent analysis on New Regionalism has, for Björn Hettne, raised important ontological questions over ‘what we study when we study regionalism’. The paper contributes to this debate by focusing on the shared beliefs, norms and rituals that hold a region together. Working between the New Regionalism literature and thinking on international regimes, this paper – to paraphrase Friedrich Kratochwil and John Ruggie – outlines the ‘inescapable inter-subjective quality’ of a region. This focus on inter-subjectivity seeks to improve on existing approaches that consider shared social structures as already fixed, and/or as autonomous constructs operating over and above regional actors. In order to appreciate how inter-subjective structures and regional agents interact with each other, the paper explores the social construction of Latin America. Specifically, it examines the politics of regionness – understood here in relation to identity, space and agents – to demonstrate how various regional actors operate within, and reconstruct, shared meaning. In so doing, it interrogates the practices that govern and continually produce the region.
