协整还是协变:来自中国进出口时间序列的经验证据(1950-2004)

结构突变是经典计量经济学所面临的难题之一,也是当前国际计量经济学界的一个前沿热点问题.本文采用带有内生结构突变的单位根检验,判定我国进出口时间序列服从具有两次结构变动的趋势平稳过程,而不是单位根过程.在此基础上进一步建立了同期协同结构突变向量自回归模型,即协变模型,得出了一些与常规的协整分析不同的结论,该模型具有更强的解释能力和更好的预测效果.

Cities, hinterlands and agglomeration shadows: Spatial developments in Finland during 1880–2004

This paper analyzes long-term spatial developments in Finland by focusing on two predictions of the new economic geography (NEG) models: the increasing persistence of locational patterns and the rising dominance of growth centers. The empirical analysis is based on regional population data from 1880 to 2004. The results support the hypotheses. Evolutions in rank and rank-size distributions during the processes of industrialization and urbanization suggest increasing persistence of regional structures. The analysis of causal processes between population centers and their hinterlands shows that these regions grew hand-in-hand in the pre-war period, whereas agglomeration shadows started to come about during the post-war period.     

Trade‐led growth hypothesis in Cuban commercial regimes since 19601,2

This study examines the impact of trade on Cuban growth during different commercial policy regimes spanning the period from 1960 up to 2004, encompassing two essential economic structural transformations: the Cuban revolution and the fall of the Berlin Wall. For this purpose, the Granger causality is used by means of the modified Wald test for augmented‐level vector autoregressive model with integrated and cointegrated processes introduced by Toda and Yamamoto (1995) and Dolado and Lutekepohl (1996) . We show an import‐led growth hypothesis during the Soviet‐oriented pattern that is rejected after 1990, when exports are not only responsive to growth expansion but also to imports’ behaviour.     

Defining Markets for Ex Ante Regulation using the Hypothetical Monopoly Test

The EU is gradually systematizing its approach to ex ante regulation (notably with the publication of the recent regulatory framework for Electronic communications). Market definition is viewed as an essential first step in this, with the ‘Hypothetical Monopoly Test’ a useful conceptual tool for use in the assessment. This paper examines the use of this test for market definition when there are several differentiated goods or services under consideration. It sets out an analytic framework, discusses the pros and cons of using the test and illustrates its use in a Telecom context.
