Philanthropic foundations are the object of little research in Canada and Quebec. Our article recognizes the role of these organizations, as well as the presence of powerful new foundations, rich in assets and donations. This article consists of three parts. The first part presents a theoretical review of the American literature published from 2000 on. The second part examines data that we extracted from three main repertoires. Though informative, these repertoires tend to classify Canadian and Quebec foundations in categories that are mostly fiscal and legal and tend to break them down as public or private foundations. We therefore question the limits of studies based on such categories. In the third part of the article we propose a theoretical framework based on a sociopolitical point of view in an attempt to transcend the binary approach. Our approach borrows from the concepts of social and solidarity economy (SSE) and plural economy in order to better understand the new institutional arrangements in which foundations operate. This theoretical framework allows us to analyse foundations as actors of the SSE even though they might not reproduce automatically the principles and the values of the SSE in their behaviours. On the contrary, from the standpoint of a plural economy we may be in a better position to develop a sound sociopolitical analysis of diverse configurations and hybrid forms resulting from emulations or transactions between the principles of the social and solidarity economy (reciprocity), the private economy (competition) and the public economy (redistribution).  相似文献

Economic views held by the general public tend to differ significantly from those of economic experts. Would these differences fade away if people were exposed to some economic instruction? In this article, the authors identify college students' preconceptions about economic issues at the beginning of the semester, verify their persistence throughout the semester, and test whether their beliefs are correlated to course performance. The authors conduct a survey at the beginning and end of the semester on a sample of first-year students taking an economic principles course. They find evidence of preconception persistence and reasoning inconsistencies, pointing to some cognitive biases as a plausible cause. Most students do not integrate the newly learned tools into their thinking process, even if they perform well in tests.  相似文献

Social capital refers to social networks and the norms of reciprocity, cooperation and trust associated with them. It can be studied at different levels of analysis. As previous literature suggests, social capital has aspects at both the individual and collective levels. However, theory development and empirical research have focused on separate, sometimes diverging levels. In an attempt to address this, this research examines the simultaneous influence of individual and regional social capital on the discovery and exploitation of entrepreneurial opportunities using individual-level data from the Global Entrepreneurship Monitor linked with regional-level data on social capital. The results show that individuals from regions with higher social capital are more likely to discover and to exploit entrepreneurial opportunities. Moreover, individuals having networks with other entrepreneurs are also more likely to identify a business opportunity and to become an entrepreneur. Also, we found that social capital at individual level had a greater effect than social capital at regional level in the two stages of the entrepreneurial process.  相似文献

The systemic change of 1989/1990 is usually identified as the critical juncture in the modern economic history of post-communist economies. While the change itself was indeed a remarkable moment in time, a branching point from which a multitude of new paths originated in most of the countries in Central and Eastern Europe, this was only partially true in the case of Hungary. If a critical juncture is sought for Hungary, it is more likely to be 1968, the year the New Economic Mechanism was launched. By applying the conceptual framework of historical institutionalism, the article argues that what made Hungary unique during the communist era and what rendered its position as a (one-time) frontrunner proved to be a serious constraint after the systemic change. The legacy of a pre-born welfare state, the constant need for compensating potential losers of any economic reform, along with short-sighted decision-making, have together generated specific path dependencies in the Hungarian trajectory of economic development.  相似文献

The aim of this article is to examine the impact of stock exchange mergers on the degree of informational efficiency. For this purpose, we apply the generalized spectral shape test for the martingale difference hypothesis to the stock returns before and after the 31 domestic and cross-border mergers completed from 1997 to 2011. The test is conducted with moving subsample windows, allowing us to detect the periods of (in)efficiency, and thus to conduct a comparative analysis for pre-merger and post-merger periods. We find that higher levels of efficiency are less frequent than lower levels of efficiency after a stock exchange merger. We also find that the impact on the level of efficiency depends on a range of merger characteristics such as the level of development, size, geographical diversification and industrial diversification of stock exchange.  相似文献

The BRICS countries in general, and China and India in particular, are now widely regarded as the areas of the world likely to challenge the economic leadership of the United States (US) and the European Union (EU). A large part of this challenge will come from rapid technological catch‐up by China and India. Yet, despite a recent rise in interest, there is limited knowledge about how and where innovation takes place in these two leading emerging countries and to what extent the Chinese and Indian territorial systems of innovation differ from those in the EU or the US. In this article we explore the geography of innovation in China and India, concentrating on understanding key territorial‐level innovation trends by country, region and technology field, using the US and the EU as benchmarks. We find significant contrasts between the geography of innovation in China and India and that of the US and the EU. First, the degree of concentration of innovative activities in both countries is extremely high. Levels of agglomeration of innovation in the coastal provinces of China, as well as in Delhi and the South of India, significantly exceed the levels of agglomeration found in the USA and the EU. Secondly, China has witnessed a more rapid increase in the degree of concentration of innovation than India. We posit that the differences in the geography of innovation between, on the one hand, China and India and, on the other hand, between these countries and the developed world are rooted in different institutional settings, different systems of innovation and different national innovation strategies.  相似文献

At a theoretical level this article discusses Piketty’s hypothesis that the distribution of income and wealth tends to become more concentrated over time when the rate of return on capital is greater than the growth rate of real output. We develop a post Keynesian model of growth and distribution showing that once capital is differentiated from wealth, the increase in income and wealth concentration actually occurs when the rate of valorization of financial and real estate assets is greater than the growth rate of real output, and that this situation may be triggered by financial liberalization.  相似文献

The present study analyses firm heterogeneity and sector‐specific technology. The theoretical model stands on the assumption of maximizing the return on capital and overcomes problems involved in simple profit maximization. The results show that a random parameter model with sector dummies and heteroscedasticity is the most appropriate model specification for distinguishing firm‐level and sector‐level efficiency and heterogeneity. The heterogeneity among firms as well as among sectors was found to be an important characteristic in Czech food processing. This holds for production technology as well as for technical efficiency. Moreover, the decomposition of total variance shows that intrasectoral differences in technologies are much more pronounced than the intersectoral differences. The differences in intrasector heterogeneity also suggest that the food processing industry will be subject to accelerated structural change in the coming years. Moreover, we found that on average the companies highly exploit their production possibilities. However, some companies cannot keep pace with competitors. Because leapfrogging does not appear to be present in selected industries (except for Milling), structural change is expected to occur in such a way that the most successful companies will strengthen their position.  相似文献
