Nations import and export biophysical resources. With many ecosystems worldwide under mounting stress, countries may be increasingly interested in knowing the extent and origin of their ecological imports and dependencies. In this paper the Ecological Footprint is used as a tool to measure the biophysical (as opposed to financial) value of international trade flows. This paper attempts to answer the following question: How large of an Ecological Footprint does a given country exert inside the borders of each of its trading partners? Records in the UN COMTRADE bilateral trade database are multiplied by a matrix of per-product Footprint yield coefficients to translate from values in dollars and tonnes to units of hectares. The results show that the largest interregional flows are from Latin to North America, and from North America to Asia-Pacific. Grouping countries by GDP, high and middle income countries appear in Footprint terms to trade predominantly with other high and middle income countries and much less with low income countries. 相似文献
ABSTRACTAlthough many studies have recognised the importance of defining specific public policies to encourage technology diffusion, many authors fail to provide a clear view about either the policies that affect the diffusion of technologies or the effect of the different political instruments. Adopting a content analysis of papers that directly or indirectly refer to the diffusion of a new technology, this study applies the integrative propositional analysis (IPA) methodology to: (a) identify the repertoire of the different diffusion policies identified by previous studies; (b) classify these policies according to the type of instruments that they use; (c) analyse the impact of each policy on the different adoption factors that may inhibit or foster the diffusion of a new technology; and (d) evaluate the scope of each type of policy in terms of the number of affected adoption factors. 相似文献
This symposium contains three papers that discuss aspects of social capital. Social capital has become a major focus of research in many social sciences. Its increased prominence in economics reflects a general increase in interest in questions that have traditionally been deemed sociological. Regardless of one's opinion of social capital per se , this broadening of questions addressed within economics has been very salutary. 相似文献
University business incubators (UBIs) are an important part of the ecosystem that supports entrepreneurial activities and economic development. Extant research has focused on examining UBI activities at a single point in time, but there is a paucity of theoretical and empirical work aimed at understanding the forces that explain why and how UBIs change over time. This is an important gap because establishing a university business incubator does not assure its development and growth. We address this issue by drawing upon the Fisher et al. Academy of Management Review, 41(3), 383-409 (2016) Identity-Legitimacy-Life Cycle model to explain how the pursuit of resources and organizational legitimacy shapes the development of UBIs along key strategic and operational dimensions, which has implications for performance evaluation over time. We illustrate with a case study about the creation and evolution of the DMZ, a leading UBI at Ryerson University in Canada. This case provides new insights about the dynamics of UBIs and their relationships with the entrepreneurial ecosystems in which they are embedded. Implications for future research, management practice, and public policy are discussed.
The National Basketball Association contracting rules provide plausibly exogenous variation in career concerns near contract end. We use this setting to study how individual career concerns affect risk‐taking behavior and can sabotage team performance. Using the frequency and duration of player injuries from 1991 to 2013 we measure individual risk‐taking behavior. We find that the average player's likelihood of missing a game due to injury falls by 0.06 percentage points (or over 100% relative to the mean injury rate) in the final 3 months of his contract, and when missing games due to injury is unavoidable, his recovery time drops by 22 days. However, “elite” players with virtually no career concerns actually miss more games due to injury. Finally, we find that elite players missing too many games and “average” players playing before healthy, combine to hurt team performance. For each additional player in the last 3 months on contract, the win probability for that team falls by over 2.6%. 相似文献
Hong Kong's role has been integral to China's unprecedented economic growth, but privatization ranks first in importance. Another key factor is Beijing's putting economic reform before political reform. Giving democracy to a society in chaos likely makes matters worse. Hong Kong and China both have profited from their partnership. As China has opened up to allow transformation into a market economy, Hong Kong has provided informational impetus for change, a capitalist model to copy, and middleman functions for China to participate in outside-world goods and financial markets. The collapse of Communism in China and elsewhere has increased the supply of cheap labour perhaps by 2 billion. Manufacturing countries with expensive labour and high cost welfare programmes—such as those in the United States, Canada, and Europe—will have difficulty. Capitalists in these countries will do well by investing abroad but not in their own countries. Though wrong in detail, the factor price equalization theorem—that international movement of goods and international movement of factors of production are equivalent—basically is correct. If China continues moving toward privatisation and joining the international community, it will become fiercely competitive, and prospects will be bright for both China and Hong Kong. However, China's recent drift from capitalism clouds those prospects. Fundamentally, three kinds of rights systems exist: (i) a capitalist system, with well defined private property rights, protected by law, where control of resources is based on ownership; (ii) a hierarchical system, such as Communism, where control of resources is based on one's rank in the hierarchy; (iii) a system of corruption, where control of resources is based on bribes and patronage. China rapidly had been making a transition from the second system to the first but recently seems to have derailed into the third. In any case, Communism's collapse is one of the great events in human history. The hero of that event is Deng Xiaoping—not Gorbachev, nor Thatcher, nor Reagan. Hong Kong, by contributing significantly to China's capitalist movement, has led the Communist world to change. 相似文献
Our purpose is to answer two questions pertinent to the international transmission of changes in equity values. First, do lead-lag relationships documented in short-horizon (daily) studies continue to hold in longer time (monthly) horizons? Second, does the lead-lag structure remain stable over time? The questions are answered by examining monthly equity returns for nine countries during the 1980s. We find evidence that is somewhat surprising—significant lead-lag relationships among some countries persist in monthly horizons, particularly during the first half of the 1980s. During the second half, the lead-lag relationships are substantially weaker. During the same period, we find that contemporaneous correlations across countries have largely increased, implying greater influence of worldwide factors in determining equity prices. 相似文献
This paper tests the effect on stock value of an expected change in future trading costs. The capitalized value of a reduction in trading costs is hypothesized to increase the stock value, a trading cost effect. Improved liquidity reduces trading costs. Inclusion as an S&P 500 Index replacement stock is an event hypothesized to increase liquidity. We use 114 observations between January 1, 1983 and October 12, 1989 of stocks added to the Index as replacements for stocks removed. The abnormal return of each stock is regressed against the ratio of the bidask spread to the price of the stock, the change in trading volume of the stock, and the open interest in the Index futures contracts at the close of the month prior to the replacement announcement. We find that the positive abnormal returns for replacement stocks are related to increased daily trading volume after inclusion in the Index. Further, the trading cost effect is proportional to percentage bid-ask spreads prior to inclusion. The trading cost effect increases as trading in derivatives of the Index increases. The volume and stock price changes after replacement are not transitory, indicating an improvement in liquidity. Three alternate hypotheses suggested in prior research to explain the abnormal returns for replacement stocks are tested. Testing each of the three models previously considered: price pressure, inelastic demand curves, and information, we find that none can be accepted with statistical confidence. The abnormal returns of Index replacement stocks are consistent with rational pricing of an anticipated reduction in future transaction costs. This anticipated reduction is capitalized in the value of the stock at the time of the replacement announcement. These results are consistent with a trading cost effect. 相似文献
