Where did all the remittances go? Understanding the impact of remittances on consumption patterns in rural China

We focus on the impact of migrants’ remittances on consumption patterns in China. Using a large homogenous sample of rural households surveyed in 2001 and 2004, we find that remittances are spent on nonhousing consumption expenditures at the margin, virtually dollar-for-dollar, when we instrument remittances and local employed earnings using proxies of social networks. Our findings are robust to intra-household division of labour and to fixed-effect for the county in which the respondents are registered. These results imply that rural households largely take remittances as permanent income and are consistent with the prevalence of circular and repeat migration in China.     

日本中小企业创新研究制度(SBIR)考察

经过多年对美国中小企业创新研究制度的研究后，日本于1999年建立了自己的中小企业创新研究制度．在此之前，日本已有许多支援中小企业的政策．但这些政策都单纯把中小企业视为应保护对象。而中小企业创新研究制度则注重中小企业的技术创新能力，旨在向那些有能力的中小企业提供特定的研究课题和经费补助．日本中小企业创新研究制度在政策实施方面也有一个与以往政策的不同点。它将创新过程分为可行性研究(Ⅰ)、研究开发(Ⅱ)和商品化(Ⅲ)3个阶段，对(Ⅰ)阶段的援助课题数量多，但每个课题的补助金额较小；而对于(Ⅱ)(Ⅲ)阶段的援助课题数量少，但补助金额较大。这样有利于保证国家经费的使用效率，提高创新成功的可能性。     

Patterns of industrialization and the flying geese model: the case of electronics in East Asia

We use the “flying geese” framework to study the change in the geography of comparative advantages in the electronics sector in East Asia, China and the USA. Doubts have been raised about the capacity of the “flying geese” model to interpret the most recent phases of Asian development, in particular as far as progress in the electronics sector is concerned. This paper takes issue against these negative conclusions on both theoretical and empirical grounds. On the theoretical side, the paper takes up the formulation proposed by Kaname Akamatsu, arguing that some of the critical observations raised against the model look to a distorted and simplified version of Akamatsu's original theory. Analyzing the behavior of the “revealed comparative advantage index” per products and area, it is concluded that the “flying geese model” is compatible with manifold industrial development models, increasing interdependence in an integrated area which crucially also includes the US, and that asymmetries and hierarchical order persist across the countries.     

Patterns of innovation diffusion and technological competition in Portuguese manufacturing and service industries

This article uses data from the Portuguese Community Innovation Survey (CIS III) to analyse the inter‐industry heterogeneity in the diffusion of innovations and level of technological competition in Portuguese manufacturing and service industries. The industries are classified with reference to the relationship between the level of participation in innovation and the strategies of innovative firms. Methods of multivariate statistics are used to synthesize the data and to group the observations into subsets. Four distinctive innovation patterns are identified, defined along the following dimensions: output‐orientation of innovation, importance of disembodied innovation, role of technologically advanced innovation and level of innovation opportunities. It is also found that high levels of technological competition tend to occur in sectors with relatively low dimension, productivity and overall investment.     

Relationships between transport emissions and travel patterns in Britain

This paper explores the relationship between transport emissions and various measures of passenger travel patterns in Britain. The paper uses original data from the 1989/91 National Travel Survey and identifies a method for incorporating a range of vehicle operating conditions into calculations of vehicle emissions and energy consumption for each journey recorded in the National Travel Survey data. The paper shows that travel distance is a reasonable proxy for vehicle energy consumption and emissions of most pollutants. Travel distance per person is therefore a simple and readily available environmental indicator for transport. This indicator has potential application in the assessment of current transport policies and programmes and in the development of future policies and programmes.     

Consumers’ perspectives on online banking services

The forces of economic change, coupled with advancements in technology, prompt banks to rethink their use of traditional branches and begin forming new partnerships to deliver financial services. The Internet seems to be the new delivery channel in the banking sector. Factors such as the security of personal data or the reliability of a financial institution have been identified by previous studies as the determinants of electronic‐banking adoption. In this paper, a series of new factors, such as the difficulties of using the Internet, are shown to play a crucial role in the consumer’s attitude – adoption or rejection – of this new alternative channel. We examine consumer behaviour by modelling multivariate categorical response data using a generalized linear model. Our choice model is based on the assumption that an individual’s decision to use electronic services depends on a number of explanatory variables, and we try to estimate the factors that affect an individual’s decision to use online services.

Measuring intensity of technological change: The seismic approach

The abundance of typologies, within the economics of innovation, has resulted in the same name being used for different innovation types and the same innovation being classified under different typologies. The present research introduces the Scale of Innovation Intensity (SIIN) based on metataxonomy that subsumes other, less comprehensive taxonomies. The SIIN is similar to the seismic Mercalli's scale used to measure the intensity of earthquakes. The impact of technological change is measured by an indicator, called magnitude, based on the impact of technological innovations on the economic system. The theory is applied to some product and process innovations such as agricultural mechanization, aircraft technology, muffler catalytic, aluminum processing, etc. The results show that some innovations have a higher technological intensity and energy (economic impact) on well-being than others. Some concluding remarks are discussed in the final part of this research.     

Structure of neutral and monotonic binary social decision rules with quasi-transitive individual preferences

The paper investigates the structure of neutral and monotonic binary social decision rules with unrestricted domain under the assumption that individual weak preference relations are reflexive, connected, and quasi-transitive. Among other results, neutral and monotonic binary social decision rules on this domain are characterized for alternative social rationality assumptions.
