The purpose of the study is to characterize different styles of work organization in French firms and their current changes and to link them to the use of specific technologies and to firms performance. The data which are used arc of two kinds: a labor force survey (1 470 blue collar) and a business survey (7 089 firms). We show that two main variables create differences among firms' organization devices: the intensity of communication within the workshop and the level of autonomy of workers (facing technological and hierarchical constraints). The use of advanced technologies and the skill of the labor force are positively linked to both organizational variables. Therefore. ‘Communicating organization’ and organizational innovation seem to aim at creating conditions for individual and collective learning on new technologies. They also enhance the ability of the firm to adapt to changing market conditions through technological innovation and inventory reduction, These views are supported by econometric estimation.  相似文献

Using the findings of the 1999 Survey of Innovation in the Canadian manufacturing sector, we analyse the impediments, i.e. the problems and obstacles, that firms in the sector face when they innovate. In particular, we assess the factors which inhibit innovation, especially with regard to by small and medium enterprises (SMEs). First we try to establish the relationship between the impediments to innovation and various firm characteristics. Then we assess whether these impediments actually prevent firms from innovating or whether firms are able to overcome them.

We find that the perception of impediments to innovation vary according to firm characteristics. For example, large firms are more likely to report the high cost of developing innovation and organizational rigidities as impediments than small firms. However, they seem to have less difficulty with regard to financing innovation projects compared to SMEs. Our results also show that firms seem to be able to overcome most of the obstacles to innovation. Therefore, the impediments featured in innovation survey(s) should not be interpreted as impenetrable barriers that prevent innovation. The sole exception is organizational rigidities. Firms facing organizational rigidities are less likely to become innovative, whether they are small, medium, or large. From our results, we conclude that small firms do not face particular impediments which prevent them from becoming innovative.  相似文献

This paper investigates how various conjoint designs (full versus fractional) and estimation procedures (LINMAP, MONANOVA, OLS) may interact with basic characteristics of the “true” utility functions (i.e., their range, shape, and curvature) when estimating attribute importance weights. Substantial weight distortions are found, especially under a fractional design.  相似文献

Exchange Rate Pass-Through and Rivalry in the Swiss Automobile Market. —This paper investigates the pricing rivalry among foreign automobile producers in the Swiss market. The main results from the dynamic analysis of two categories of automobiles between 1977 and 1991 are: First, the degree of exchange rate pass-through differs among source-countries despite the absence of quantitative restrictions on imports and of domestic production facilities. However, for some countries, pricing strategies show remarkable consistency across product categories and time spans. Second, the degree of exchange rate pass-through is low, especially in the market for small-size automobiles. Third, this low degree of pass-through may be attributed to a low degree of competition among foreign sellers.  相似文献

We propose a transactions cost theory of total factor productivity (TFP). In a world with asymmetric information and transactions costs, productivity must be induced by incentive schemes. Labor contracts trade off marginal benefits and costs of effort. The latter include, in addition to the workers' marginal disutility of effort, organizational costs and rents. As the economy grows, contracts change endogenously, inducing higher effort and productivity. Transactions costs are also affected by societal characteristics that determine the power of incentives. Differences in these characteristics may explain cross‐economy productivity differences. Numerical experiments demonstrate the model's consistency with time‐series and cross‐country observations.  相似文献

The investment performance of a Canadian portfolio of Canadian public real estate companies is analyzed over the period 1971–79. Using Sharpe's index of performance, it would appear at first sight that this portfolio exhibited remarkable superior performance. Moreover, this conclusion is not due to some peculiarity of the Sharpe measure: results using Treynor's measure suggest a similar conclusion. We then apply the significance tests recently recommended by Jobson and Korkie (1981). When their preferred test is applied, we are unable to reject the null hypothesis that the real estate portfolio did not exhibit superior investment performance. This result illustrates the necessity of performing adequate statistical significance tests whenever investment performance is being evaluated.  相似文献

This study outlines potential futures for the global economy through the 2050 with a specific focus on the countries of Asia. With underlying assumptions about population and output growth, a baseline scenario assesses the growth of greenhouse gas emissions and the ensuing impacts on the climate. Under the baseline scenario, Asia's high growth leads to a strong rotation in global output and emissions by the year 2050. The analytical framework traces back the changes in temperature to economic damages – limited to the agricultural sectors. Parts of Asia are likely to see much higher dependence on food imports as a consequence of these damages. Various carbon tax scenarios are implemented to assess the potential for reducing carbon emissions. Because of the structure of their economies, Asian countries are likely to bear the greatest burden in reducing emissions in an efficient global tax scheme, but there is significant scope to ease this burden through financial transfers.  相似文献

Genetically modified rice with a high folate content, i.e., folate biofortified rice, was recently developed to tackle folate deficiency. A consumer segmentation study is conducted to explore its market potential in the Chinese Shanxi Province, where the burden of folate deficiency is among the world’s highest. Cluster analysis of 451 rice consumers identified three segments: enthusiasts (14.2%), cautious (41.2%), and opponents (44.6%). Enthusiasts obtain the highest score of GM food knowledge and attitudes and have the highest GM rice acceptance rate, followed by cautious and reluctant consumers. Regarding GM food information, enthusiasts use almost entirely audiovisual channels and rely more on the industry, while other segments depend more on informal channels and anti-GM sources. Trust levels in these channels/sources differ between enthusiasts (high), opponents (neutral), and cautious (low). Based on multinomial regression, a targeted communication approach is recommended with a focus on female, cautious consumers and rural, low-educated opponents.  相似文献
