新商品开发中的VE和创造性

价值工程所指的价值通常限定于“使用价值”,其使用价值又由功能价值和美学价值构成.以往价值工程主要围绕商品的功能价值的设计与改进而展开,本文拟在价值工程应用领域以美学价值为主的新商品开发方面作一些理论性的研究与探索.     

The impact of the tomato agroindustry on the rural poor in Mexico

This article addresses the issue of whether the tomato agroindustry (TAI) has been an effective instrument in the reduction of rural poverty. The TAI is by far the most important agroindustry in Mexico in terms of exports and employment creation. Most of the laborers employed by the TAI in northwest Mexico are temporary migrants coming from poverty-stricken regions in southern Mexico. Conditions of poverty-induced migration are explained. The characteristics and strategies of large, modern tomato enterprises are analyzed. The main conclusion is that migrant income earned in the tomato fields and packing plants, is fundamental for the bare survival in villages in poverty-stricken regions. However, this does not provide a solution to poverty alleviation because migrant income is not sufficient to contribute to capital formation in the migrating communities, or the to create the conditions for endogenous local development.     

On Terms of Trade and Capital Accumulation

This paper studies, within an OLG general equilibrium framework, the role of relative factor intensities in determining the relationship between the terms of trade and the capital stock. It shows that a diversified production equilibrium can be characterized by a positive association between these two variables if the investment sector is more labor-intensive and sector technologies are relatively dissimilar. Therefore, capital accumulation and terms-of-trade improvements do not require an import sector growing faster than the export sector when the latter is more capital-intensive. Large Stolper–Samuelson effects on factor incomes drive the results.     

Foreign bank participation and access to credit across firms in developing countries

Combining responses from a survey of firms operating in 35 developing and transition economies with data on the degree of foreign bank presence across these countries, we investigate whether higher foreign bank participation improves the accessibility of external financing for firms. The results suggest that all enterprises, including small and medium-sized ones, report facing lower financing obstacles in countries having higher levels of foreign bank presence. The results are robust to the inclusion of many controls and to econometric adjustments for the potential endogeneity of foreign bank presence and for the likely correlation of responses across firms within countries.

Strategic procurement, openness and market structure

We examine strategic procurement behaviour by governments and its effect on market structure in sectors, such as defence and pharmaceuticals, where the government is the dominant consumer. In a world economy with trade between producer countries, and between producers and non-producers, we use a modified Dixit–Stiglitz utility function with an independent taste for variety. There is free entry and exit by firms, but by anticipating their participation constraint governments can indirectly choose the number of domestic firms and their size through its choice of procurement price. Unlike the standard model with no independent taste for variety and no external sector of non-producer countries, there are incentives for subsidies, openness impacts on industrial structure and procurement coordination between producer countries affects firm numbers.     

The changing role of science in the innovation process: From Queen to Cinderella?

An overview of how the role of science in relation to innovation has been defined over the past five decades is given, showing a change from a linear to a chain-linked model of interpretation. A third analytical grid, leading to a new model is proposed, summarizing the current research on the nature of economically useful knowledge, the diversity of intervening players in learning and the outcomes of innovation. While the chain-linked view surpassed the linear model by emphasising that science is part of the process but not necessarily the initiating step, we need today to explicitly acknowledge the multi-player dimension of innovation and the wider institutional setting where distinct forms of learning take place. The reason is simple: almost all high added value products embody elements of scientific knowledge. But science is only one of a plurality of other sources of knowledge that induce innovation-based growth. More attention should also be given to understanding markets and organisations.
