This article, the eighth in a series on the new millennium, describes timelines that provide the setting and context for basing very long forecasts. The longer and more complete the historic patterns of past and present, coupled with conceptual possibilities and prospective developments, the clearer the pattern of ongoing incremental change becomes. Likely patterns of continuing change literally “pop out” when assessing such chronologies. Feasibility, credibility and practicality of 1000 year forecasting typically is dismissed out-of-hand. To help dispel such mindsets, timelines covering wide-ranging natural science phenomena spanning thousands to billions of years are presented here. Depicting the coming and going of familiar natural science phenomena in this manner reveals how the future fate of the world we live in is predetermined. These very long horizons suggest potentials for projecting physical science possibilities a mere 1000 years into the future.  相似文献

We compare the performance in employment, wages and productivity for domestic plants acquired by new domestic and foreign owners. Prospective foreign owners pick large, high‐wage, high‐productivity plants, while new domestic owners choose average performers of above‐average size. Employment, labour productivity, and total factor productivity decline in domestic acquisition targets before acquisitions; only wages recover afterwards. Employment, wages and labour productivity increase after foreign acquisitions. The sample selection introduced by long‐term comparisons and a focus on unique events introduces a downward bias into the results for domestic acquisitions and an upward bias for the foreign acquisitions.  相似文献

North American “future studies” and the French concept of “prospective” have been integrated to provide the basis for an attempted “Canadian Synthesis” in the approach developed by the Montreal-based think-tank, the Gamma Institute. In this paper the founding president of Gamma outlines the four stages of the approach in a conceptual framework entitled the “Chronospace” and illustrates its applicability by referring to some of Gamma's projects in the last 12 years.  相似文献

For marriage markets [Gale, D. and Shapley, L.S., 1962, College admissions and the stability of marriage, American Mathematical Monthly 69, 9–15.] so-called fair matchings do not always exist. We show that restoring fairness by using monetary transfers is not always possible: there are marriage markets where no amount of money can guarantee the existence of a fair allocation.  相似文献

What is the role of “large players” (e.g., hedge funds) in speculative attacks? Recent work suggests that large players move early to induce smaller agents to attack. However, many observers argue that large players move late in order to benefit from interest‐rate differentials. We propose a model in which large players can do both. Using data on currency trading by foreign (large) and local (small) players, we find that foreign players moved last in three attacks on the Norwegian krone during the 1990s. During the attack on the Swedish krona after the Russian moratorium in 1998, foreign players moved early. Gains by delaying attack were small, however, because interest rates did not increase.  相似文献

D. Blackwell and L. Dubins (1962, Ann. Math. Statist.38, 882–886) showed that opinions merge when priors are absolutely continuous. E. Kalai and E. Lehrer (1993, Econometrica61, 1019–1045) use this result to show that players in a repeated game eventually play like a Nash equilibrium. We provide an alternative proof of merging of opinions that clarifies the role of absolute continuity while casting doubt on the relevance of the result. Persistent disagreement, the opposite of merging, allows the construction of a sequence of mutually favorable “bets.” By a law of large numbers, both agents are certain they will win these bets on average. This certain disagreement violates absolute continuity. Journal of Economic Literature Classification Numbers: C11, C69, C72, D83.  相似文献

Financial poverty indicators assess which people have few financial resources and are thereby at risk of having an unacceptably low living standard. Most countries use one or several “official” poverty indicators, but they typically use either an absolute or a relative benchmark to determine what is unacceptable; absolute benchmarks are based on basic needs or rights while relative benchmarks depend on what is considered to be a “normal” living standard. Applying the absolute U.S. and the relative EU poverty indicators on the U.S. and 15 EU member states, this research shows that it makes sense to use both benchmarks.  相似文献

The paper seeks to understand how eight companies in the European car industry responded to changing business conditions under the threat of regulation on the waste problem of end-of-life vehicles. It was observed that the companies pursued diverging innovation tracks in dealing with the regulatory pressure, although competing in the same markets and subject to similar regulatory pressure. The case is interesting to consider in the light of recent discussions of differences in styles of innovation. The question then is whether any sort of style of innovation may be distinguished in the diverging innovation tracks. The objective of the paper is to add to these discussions by considering the results of this case study in the light of “similarity” and heterogeneity hypotheses that may be advanced around “styles” of innovation.  相似文献

This paper provides empirical evidence that there is no convergence between the GDP per‐capita of the developing countries since 1950. Relying upon recent econometric methodologies (non‐stationary long‐memory models, wavelet models and time‐varying factor representation models), we show that the transition paths to long‐run growth (the catch‐up dynamics) are very persistent over time and non‐stationary, thereby yielding a variety of potential steady states (conditional convergence). Our findings do not support the idea according to which the developing countries share a common factor (such as technology) that eliminates per‐capita output divergence in the very long run. Instead, we conclude that growth is an idiosyncratic phenomenon that yields different forms of transitional economic performance: growth tragedy (some countries with an initial low level of per‐capita income diverge from the richest ones), growth resistance (with many countries experiencing a low speed of growth convergence), and rapid convergence.  相似文献

Economic studies of the Roma population, which is the largest and the poorest ethnic minority in Europe, remain sparse due to the limited availability of appropriate micro level data. This paper provides a comparative analysis of life satisfaction between Roma and non‐Roma young adults aged between 15 and 24 years using survey data collected from Serbia in 2010 and from Bosnia and Herzegovina in 2011. Results from raw answers show that the young Roma population living in settlements is less satisfied with life than non‐Roma. However, we find instead that the former group is more satisfied once we account for the fact that Roma have more disadvantaged characteristics on average. Also, Roma young adults expect a better life within one year compared to the non‐Roma in Serbia while there is no difference in Bosnia and Herzegovina.  相似文献
