The ethnically homogeneous middleman groups (EHMGs), which are informal trading networks, are ubiquitous in less-developed economies where the legal infrastructure for contract enforcement is not well developed. This paper develops a formal model of social interaction among members of the EHMG as well as in more general situations in a multi-ethnic or multi-cultural society consisting of identifiable ethnic or linguistic groups. Behavioral patterns are transmitted between generations and altered via imitation in social contacts. The model demonstrates how different discriminatory behavioral patterns can evolve and persist over time. One result is that the trust between such groups can increase due to a higher frequency of inter-group contacts. In concluding the paper, we speculate about how the model can be expanded to include changes in legal structures, especially contract law. This could lead to an increase in the trust between the different groups. 相似文献

Outsourcing,Importing and Innovation: Evidence from Firm‐level Data for Emerging Economies 下载免费PDF全文
This paper investigates two sourcing strategies of firms, outsourcing and importing, and links these to innovation activities. The authors examine this empirically using firm‐level data for 28 emerging market economies and find robust evidence that outsourcing increases the likelihood to spend on R&D and via this channel raises innovation output, whereas importing increases innovation output, but not R&D. The results hold when implementing an instrumental variables approach. It is found that results crucially depend on the institutional environment in the economy, e.g. property rights and intellectual property rights protection. The results suggest that better institutions magnify the gains from importing, but not from outsourcing. EU countries also reap additional positive innovation effects from importing compared with non‐EU countries. 相似文献

The aim of the present study was to investigate consumers' awareness, acceptance and attitudes towards functional foods in Turkey. Eight hundred and eight people participated in this study: aged between 20 and 80 years, 38.5% were male and 61.5% were female. Participants were given a questionnaire and were asked to fill it in by themselves to minimize the influence of the interviewer. Results indicated that socio‐demographic characteristics such as age, education level and income level are important indicators of consumers' awareness and consumption of functional food. The results show that the female respondents were 2.987 times more aware of functional food than the male respondents. Similarly, the likelihood of respondents having awareness of functional food was 1.431 times greater among those who had a higher educational level than among those with a lower educational level. Consumers who used vitamin supplements were 1.228 times more aware of functional food than other consumers. The results show that older respondents were 3.395 times more aware of functional food than younger respondents. Respondents with a history of familial diseases were more likely than others to have consumed margarine with plant sterol, fruit juices fortified with vitamin C, and breakfast cereals fortified with vitamins and minerals. Those with a diet‐related problem were more likely to have consumed cholesterol‐lowering products than those without a problem. As a conclusion, this study has shown that socio‐demographic characteristics such as age, education and income levels, and prices are important indicators that influence consumers' awareness and consumption of functional food. These results suggest that this type of knowledge could affect consumers' interest in functional foods, and therefore educational strategies might be necessary to encourage the consumption of functional foods. 相似文献

In Turkey, the empirical results on the link between financial development and economic growth are mixed. The existing studies do not take into account the fact that Turkey has experienced endemic political and economic instabilities over extended periods. This study aims to analyse the role of macroeconomic instability and public borrowing on the finance–growth nexus in Turkey by using time series econometric techniques over the 1980–2010 period. In doing so, we attempt to extend the existing literature by taking into account the role of macroeconomic instability as well as public borrowing. Our results reveal that there are additional – albeit indirect – channels between finance and growth via the effects of macro instability and public borrowing on financial development and economic growth. After taking into account the effects of overall instability and public borrowing, we found that growth–financial development relationship is bidirectional and permanent. In other words, in Turkish case, economic growth and financial development are jointly determined. Thus, our results shed some light on the ambiguity of the evidence on the link between financial development and economic growth for Turkey. 相似文献

Innovation speed is widely considered to be a key factor for a firm's ability to maintain competitive advantage. Primarily, empirical evidence has found contradictory interdependencies regarding the role of innovation speed. The prevailing proposition of “the faster the better” has been challenged by results of empirical studies heavily depending on the methodological setup used. In contrast, we propose a model of the complete innovation process to study innovation speed under uncertainty and competition. We find that higher market uncertainty speeds up innovation and encourages firms to innovate incrementally. Strong competition tends to reduce innovation speed and encourages rather radical innovation. 相似文献

Welfare-state transformation and entrepreneurial urban politics in Western welfare states since the late 1970s have yielded converging trends in the transformation of the dominant Fordist paradigm of social housing in terms of its societal function and institutional and spatial form. In this article I draw from a comparative case study on two cities in Germany to show that the resulting new paradigm is simultaneously shaped by the idiosyncrasies of the country's national housing regime and local housing policies. While German governments have successively limited the societal function of social housing as a legitimate instrument only for addressing exceptional housing crises, local policies on providing and organizing social housing within this framework display significant variation. However, planning and design principles dominating the spatial forms of social housing have been congruent. They may be interpreted as both an expression of the marginalization of social housing within the restructured welfare housing regime and a tool of its implementation according to the logics of entrepreneurial urban politics. 相似文献
