The marginal-products-of-labour (MPL) wage gap is studied in the early-reform Chinese economy, using the Olley-Pakes estimation technique to estimate the production function, based on micro data including different categories of labour. From this measurement of MPL-wage gaps and econometric analyses, several conclusions are drawn. First, the MPL-wage gap was anomalously large for managers in state-owned enterprises (SOEs) compared with other categories of labour. Second, the large MPL-wage gap of managers raised the average MPL-wage gap across various categories of labour, resulting in higher than the average wage MPL throughout the entire workforce, which is regarded as homogeneous. Third, the large MPL-wage gap, or, in other words, the under-employment of managers, occurred not only because the state still centrally employed and allocated labour to SOEs, but because the economy faced a labour-supply constraint of managers in early-reform China. This observation supports a modified version of the state labour-monopsony hypothesis.     

Understanding early diffusion of digital wireless phones

There is increasing empirical evidence from academic research and strong recognition among policymakers that wide diffusion and innovative uses of digital wireless phones are important sources of a country's economic growth and social development. Adopters do not necessarily adopt digital wireless phones at the same time though. Although the diffusion of innovation theory suggests five adopter categories according to their degree of innovativeness, this approach lacks theoretical justification and, more importantly, it makes a critical assumption of a normal distribution of adopters that needs empirical validation. This study investigates the basis for defining different adopter categories and factors that affect adoption decisions of digital wireless phones using the aggregate data on 46 developed and developing countries from 1992 to 2002. This paper utilizes a two-step analysis approach. The first step evaluates the distribution of adopters over time using various diffusion models. The second step uses iterative survival analysis to examine the patterns of influential factors on adoption behavior by evaluating the survival models using a 1% increment of cumulative penetration as the targeted events. The results of the best-fitting diffusion models indicate that digital wireless phone adoption patterns did not follow a normal distribution and did not map exactly into Rogers’ five adopter categories. The results from the iterative survival analysis suggest four adopter categories (innovators, early adopters, breakthrough adopters, and mainstream adopters) among the first 30% of adopters. Different factors are observed to influence various adopter categories’ adoption decisions. The results offer insights to support telecommunication operators to develop strategies to attract these adopters. It also supports policymakers’ efforts to design effective regulatory frameworks.     

Determinants of agro-food trade competition of Central European countries with the European Union

The two-way trade flows are classified into four competition categories: successful price competition when trade surplus is at lower export than import price, unsuccessful price competition when trade deficit is at higher export than import price, successful quality competition when trade surplus is at higher export than import price, and unsuccessful quality competition when trade deficit is at lower export than import price. Using a panel dataset of determinants of agro-food trade competition between the five Central European Countries (Czech Republic, Hungary, Poland, Slovakia, and Slovenia) and the European Union, we found the effect of trade balance on trade competition to be more significant than the effect of export–import unit values. Natural, and to a lesser extent human factor endowments increase price and quality competition and reduce unsuccessful price and quality competition. R&D expenditures improve quality competition and reduce price competition. Foreign direct investment reduces unsuccessful price competition and increases unsuccessful quality competition. The size of the economy improves price competition and reduces quality competition. Consumer demands associated with higher level of income per capita increase unsuccessful price and quality competition.     

汉语中“不A不B”格式语义关系之考察

汉语中"不A不B"是一种很常见的四字格.它的结构严密紧凑,格式整齐均匀,音调和谐上口,而且节奏鲜明,表述精练,含义丰富,因而在语言中使用频率很高.对于中国人来说,这种格式比较容易理解,而在对外汉语教学中,很多学生经常会把这种格式理解为简单的否定,本文以"不A不B"格式的语义关系为分析对象,把A和B在语义上大致分为三类:同、近义,对、反义和同属于一个类属义场来分析"不A不B"的语义关系类型并考察其在语境中的运用.

A ranking of journals for the aspiring health economist

This article identifies and ranks 104 journals that might logically serve as the core for the interdisciplinary field of Health Economics. These journals are identified by analysing approximately 15 000 articles contained in the current CVs of 100 top health economists. Of the nearly 1200 journals spanned by these CVs, 104 journals were outlets for more than five of these top health economists. The 104 journals are ranked using eigenfactor and article influence scores as well as the percentile rank for each journal within its Institute for Scientific Information category. The primary intention is to create a broad-based journal list that exposes possible research outlets for aspiring health economists and to report the relative rankings of such outlets using established metrics.
