China and international market integration: Evidence from the law of one price in the Middle East and Africa

We model market integration in the Middle East and Africa by analyzing price dispersion and testing the law of one price (LOP) on highly-comparable actual local retail prices of 135 goods and services across 23 countries in the region over the period of 1990–2016. Second-generation panel estimators are applied to four price benchmarks: Regional average, South Africa, China, and US prices. Cross-regional price dispersion diminishes considerably over time up to 2008, particularly for non-tradeables around China price. The test of LOP indicates the percentage of convergent prices is highest in China price benchmark, followed by US, South Africa, and regional average benchmarks. Direct estimation of the convergence speed confirms this order. Overall, the results show evidence of increasing market integration in Middle East and Africa but it appears to be driven by global forces and, especially, the rise of China as a new economic power. The results show that some emerging market economies, such as China, can step up and promote integration while traditional economic powerhouses, such as the USA and UK, disengage from international economic relations.     

Is current institutional quality linked to legal origins and disease endowments? Evidence from Africa

This paper empirically assesses if and to what extent cross-country differences in institutions inherited from the past affect current institutional quality in Africa. Specifically, the work evaluates if legal origins and disease endowments explain cross-country differences in the quality of contemporary institutions that are widely considered to be important for financial system development and other economic outcomes, such as those related to creditor rights protection and the credit information infrastructure, as well as the judicial, legal property and insolvency systems. Empirical tests are carried out on a sample of 46 African former European colonies with data on current institutional quality from 2004 to 2013. The findings reveal that the legal origins hypothesis receives strong support in the data: historical factors, rooted in legal origins, have long-lasting effects on current institutional quality in the African context. Mixed evidence is instead found for the endowment view.     

《土地管理法》成片开发征收标准的体系阐释

研究目的:阐明《土地管理法》成片开发征收标准的核心要旨及其体系构成。研究方法:规范分析法,文献分析法。研究结果:成片开发标准应当以促成公益目的实现为核心要义,并秉持系统思维,既要明确其面积范围、用地构成及类型、补偿方式等基本构成要素,还应建立征收权行使之事前、事中、事后全过程动态监控机制。研究结论:成片开发征收入法本身具有权宜性,待土地要素市场化配置机制更加健全,成片开发征收完成特定历史时期使命之后应退出公益征收范围。     

创新网络领域知识主题研究述评

在知识经济时代，创新网络在企业创新中扮演着重要角色，而研究网络中知识要素的产生、传播、吸收等问题对了解企业网络化创新具有重要意义。基于国内外核心文献数据库，收集创新网络领域知识要素相关文献，并结合文献计量分析方法，对该领域近30年有关知识主题研究的演化规律、整体趋势等进行梳理。结果表明，国内外研究年度发文量均呈现3个阶段变化趋势，且分别拥有各自重要载文期刊，国内研究已形成核心团队，而国外并未形成；国内外研究既有相同之处，也存在差异性，且均形成较为清晰的研究框架；在演化规律上，国内横向拓展和纵向深化研究特征显著，而国外更加注重纵向深入探索分析，研究内容也更加分散；在未来前沿热点分析上，中外学者关注内容既有相同点，也有不同点，知识协同、知识惯例、企业数字化转型对知识影响的研究是未来关注重点。     

Defending Gibrat’s Law as a long-run regularity

According to Gibrat’s Law of Proportionate Effect, the growth rate of a given firm is independent of its size at the beginning of the period examined. While earlier studies tended to confirm the Law, more recent research generally rejects it. This article reconciles these two streams of literature, taking into account the role of market selection and learning in reshaping a given population of firms through time. Consistently with previous studies, we find that Gibrat’s Law has to be rejected ex ante, since smaller firms tend to grow faster than their larger counterparts. However, a significant convergence toward Gibrat-like behavior can be detected ex post. This finding is an indication that market selection “cleans” the original population of firms, so that the resulting industrial “core” does not depart from a Gibrat-like pattern of growth. From a theoretical point of view, this result is consistent with those models based on passive and active learning, and can be seen as a defense of the validity of the Law in the long-run.

Market integration and convergence to the Law of One Price: evidence from the European car market

This paper exploits the unique case of European market integration to investigate the relationship between integration and price convergence in international markets. Using a panel data set of car prices, we examine how the process of integration has affected cross-country price dispersion in Europe. We find surprisingly strong evidence of convergence towards both the absolute and the relative versions of the Law of One Price (LOOP). Our analysis illuminates the main sources of segmentation in international markets and suggests the type of institutional changes that can successfully reduce it.     

论法治化财政

财政的法治化是公共财政建设的重要内容.本文讨论法治化财政的理想指标体系,并结合中国现实,对中国财政的法治化进程进行定性评价.理想的财政法治化指标体系至少应涵括六个方面的内容:财政的民主立法、财政的法律至上、财政法律体系的完备(健全性)、财政的权利保障度、财政的司法公正、财政行政行为的受约束程度.中国财政立法奉行了民主立法原则,但民主立法进程仍需进一步加快;财政行为的法律至上度有待进一步提高;财政法律体系虽已覆盖财政各领域,但立法层次低,立法质量不高,法律体系尚不够完备;财政的权利保障度和财政司法的公正性正在得到逐步改善;财政行政行为已经有了各种各样的法律约束,但是财政法律体系的不健全从根本上影响了约束程度.     

经济全球化下海关法面临的挑战及对策

经济全球化对各国海关的最大挑战就是如何处理好海关有效监管和便利贸易之间的矛盾。20世纪90年代以来各国海关法纷纷进行改革以适应经济发展需要。改革的主要内容包括:改革海关组织和通关程序,实现快捷通关、促进贸易发展;合理分配权利和义务,满足通关效率的需要;海关法的立法体例凸现通关制度的模式等。海关法的渊源则表现为国内海关法的国际化、国际海关法的国内化、区域海关法的兴起等特点。中国海关法应进一步完善海关法律体系,以适应经济全球化的挑战。     

实施知识产权战略——我国企业应对美国337条款的有效途径

我国加入世贸组织之后,中美之间的贸易战逐渐出现一些新的变化,在反倾销措施不断加强的同时,美国正在越来越多地使用对贸易和知识产权限制更为严格的337条款作为保护其贸易的手段,使中国企业蒙受了巨大的损失。因此,实施知识产权战略,是我国企业维护自身利益,跨越美国337条款这道贸易壁垒最有效的途径。     

我国存在最优政府规模曲线吗

本文运用格兰杰方法对我国1978-2004年政府支出与经济增长的因果关系进行检验,结果表明:经济增长是我国政府规模的格兰杰原因,但政府规模不是经济增长的格兰杰原因。这一结论说明我国并不存在最优政府规模曲线,但验证了瓦格纳定律,同时也为我国现阶段的财政政策取向提供了有益的参照。
