Incorporating Generalized Marginal Budget Shares in a Mixed Demand System

This article extends a Rotterdam type of mixed demand system by replacing its constant marginal budget shares with the ones derived from originally defined and specified mixed Engel curves that take a generalized functional form using the Box-Cox transformation. An empirical illustration is given for Japanese demand for fresh and processed fruits and vegetables. The results show that the Rotterdam parameterization of marginal budget shares, which corresponds to those in linear mixed Engel curves, is preferred by the data, and that improper assumptions of the form of mixed Engel curves underlying a mixed demand system can bias its elasticities.     

区域汽车贸易规则比较研究

区域汽车贸易规则是区域贸易协议的重要组成部分,其核心内容是确定区域内优惠关税。为了防止CKD生产方式,多数区域汽车贸易规则制定了汽车原产地规则。研究表明,区域汽车贸易规则对区域贸易特别是汽车零部件区域贸易产生了重大影响。     

Optimal Discretion

We investigate the desirability of adopting a rule in favor of discretionary monetary policy in a model exhibiting Kydland and Prescott's dynamic inconsistency problem but no fundamental incompatibility between the policymaker's price stability and full employment objectives. We show that if discretion provides a policy flexibility benefit, then a rule is optimal only when inflation exceeds an endogenously determined threshold. This gives rise to a discretionary policy zone for inflation with the central bank taking more drastic action towards stabilizing inflation when inflation veers outside the zone. Imperfect credibility narrows the scope for discretion and enhances the benefits of adopting a rule.

BUILDING PUBLIC-PRIVATE PARTNERSHIPS: Assessing and managing risks in port development

In recent years increasing dependencies between public and private organizations lead to a growing need for public-private partnerships. However, cultural and institutional differences between the public and private domain and, in addition, the difficulties of bringing the two together, constitute a serious threat to successful public-private partnership. The formation of these partnerships is further hindered by confusion of the concept of public-private partnership. The predominant model of contracting out restricts rather than enhances public-private interaction. This article deals with the difficulties and risks involved in building public-private partnerships and tries to answer the question of how to overcome them. The issue is illustrated by an analysis of the attempts made to realize a huge port expansion in the port of Rotterdam by means of establishing public-private partnership.     

知识守门者企业间领导力与产业集群升级

作为产业集群中的核心异质性主体,知识守门者对于产业集群的知识更新和开放式升级至关重要。结合联盟管理中的企业间领导力理论,从知识守门者自身知识基础、网络能力和网络位置优势探讨了其在集群中的企业间领导力形成机理。在此基础上,将知识守门者在产业集群中的领导力划分为技术领导力、平台领导力和制度领导力3个维度。此外,结合湖南新材料产业集群案例,探讨了该集群中知识守门者科力远公司的技术领导力、平台领导力和制度领导力构建途径及其对集群升级的影响,研究结果证明了理论的合理性。最后,基于理论与案例结论,提出了促进我国集群开放式升级的若干政策建议。     

VALUE CONTENT AND PRODUCTION NETWORKS IN SOUTHEAST ASIA: APPLICATION OF AFTA AND ASEAN‐PLUS‐ONE FTA FORMULAS

Rules of origin are an integral part of all trade rules. To be eligible for Common Effective Preferential Tariffs under the ASEAN Free Trade Area (AFTA) agreement, a product must satisfy the conditions relative to value content. The present paper seeks to calculate value content of industries in Southeast Asia, using the formula specified by the rules of origin in AFTA, the ASEAN–China FTA, the ASEAN–Korea FTA, and the ASEAN–Japan FTA. Moreover, the paper attempts to calculate true value content of industries by applying a simple technique of input–output analysis, and to estimate error margins (i.e., overestimates) in calculating value content. The paper also examines the relationship between value content and production networks. The paper finds that many industries exhibited declines in local content during the period 1990–2000, but that the geographical spread of production networks raised the proportion of inputs supplied by the neighboring ASEAN countries, so that the contribution of the cumulative rule of origin increased.     

Choosing one’s own informal institutions: on Hayek’s critique of Keynes’s immoralism

In the main, Hayek favored rules that apply equally to all and located such rules in tradition, beyond conscious construction. This led Hayek to attack Keynes’s immoralism, i.e., the position that one should be free to choose how to lead one’s life irrespective of the informal institutions in place. However, it is argued here that immoralism may be compatible with Hayek’s enterprise since Hayek misinterpreted Keynes, who did not advocate the dissolving of all informal rules for everybody. By avoiding this misinterpretation, immoralism can be seen as institutional experimentation at the margin, which Hayek himself favored.

Philosophy of Economics Rules: introduction to the symposium

ABSTRACT

Economists have long been criticized for their use of highly idealized models. In Economics rules: Why economics works, when it fails, and how to tell the difference [Oxford: Oxford University Press, 2015] Dani Rodrik responds to this criticism by offering an account of models that emphasizes the diversity of models in economics. Rodrik’s account presents a rare opportunity for economists and philosophers of economics to engage in a mutually beneficial exchange that could improve our understanding of the power and limits of economics, and the rights and wrongs of the dismal science. The symposium on Rodrik’s Economics Rules is the first attempt to seize this opportunity.     

美国碳关税政策对中美贸易的影响

基于环境保护和贸易保护的目的,美国提出了征收碳关税诉求。这将对中国对美国的商品出口产生什么样的影响?本文根据我国各行业的碳排放强度和出口贸易细分数据,分析了美国征收碳关税可能会对我国各行业出口贸易的影响,并提出,中国应该在多边贸易组织的框架下对美国将实行的碳关税政策进行限制约束,及时调整国内产业结构。
