The concepts of resource frontier and commodity frontier are often treated interchangeably. This article suggests the benefits of clarifying these concepts because frontiers remain important analytics for understanding drastic land‐use changes and other socio‐environmental transformations. Based on long‐term field research in different parts of South and Central America, we use frontier concepts as heuristic devices to analyze heterogeneous frontier situations and make broader generalizations. Our synchronic and diachronic analyses of frontier dynamics elucidate different frontier modalities and shifting frontier expansions. The concept of commoditizing resource frontier is introduced to explain recent frontier‐makings in Brazilian Amazonia and Cerrado and in the Nicaraguan Río San Juan. Although earlier frontier research took a short‐term time perspective and created conceptualizations based on a single modality of a particular period, our longitudinal analysis shows that drastic changes and complex overlappings are the hallmarks of frontier dynamics.  相似文献

Applying business theatre can not only make a contribution in the context of change management, learning and development processes in companies, but also in the new service development (NSD) process. The authors show how business theatre can be applied in each step of NSD and present insights that they gained from a students’ and a research project. As service theatre addresses the “emotional side”, it is an ideal complement to a systematic NSD approach that addresses the “rational side” of a service.  相似文献

The following article throws some light on the (fragile) legal foundations of the Galileo Project, the European Satellite Navigation System, and gives an interpretation of the normative procurement rules of the EU. Additionally it tries to reveal the practical problems of upholding the principle of free competition and an open market in as much as the procurement of high technology concerns a highly olipolistic market.  相似文献

Abstract

The idea of “Smithian growth” rests on a “natural” development out of agriculture through capital accumulation, and the division of labour. We confront these concepts with an “historical experiment” and the case of Danish agriculture in the nineteenth century. Specifically, we look at how accounting was used to promote specialization, ultimately in butter production, leading to the massive increases in productivity that Smith predicted. We also observe the emergence of Smithian “philosophers”. This ultimately led to the capital-intensive industrialization of Danish agriculture through butter factories, and general development. We argue that this establishes the historical relevance of Smith’s theories.  相似文献

Schumpeter 1911: Farsighted Visions on Economic Development   总被引:2,自引:0,他引:2  
This paper presents to the English-speaking reader a sample of material contained only in Schumpeter's first German edition (1911) of Theorie der wirtschaftlichen Entwicklung , material subsequently omitted from later German editions and from the English translation. The newly-translated material, presented here for the first time in English, comprises a substantial part of the second chapter, only available in a completely rewritten version, and fully half of the famous seventh chapter, which has not been previously available at all in English. This material merits attention today because it contains remarkable and farsighted visions on economic theory that may inspire current efforts to devise models of economic and social evolution. In order to better appreciate the original text, we briefly introduce the "background" to Theorie and its revisions, briefly describing the social and intellectual environment of the time. We then discuss how the entrepreneur evolved over the three editions of Theorie (from 1911 to 1934) in view of the shift in Schumpeter's personal and intellectual life and outline the most important implications raised by the first German edition of 1911. Finally, we use Schumpeter's own statements to settle the obstinate confusion on the publication year of Theorie in favour of the year 1911.  相似文献

Notwithstanding their common features, hedge funds remain an extremely diverse asset class. Information on fund styles is important for numerous purposes, such as portfolio construction, performance attribution and risk management. With fund self‐declaration being prone to (strategic) misclassification, return‐based taxonomies grouping funds along similarities in realized returns provide a useful alternative. We provide a consistent classification system of homogeneous groups of hedge funds based on self‐organizing maps. Whereas some fund categories such as managed futures are largely consistent in their self‐declared strategies, others, especially so‐called ‘equity hedge’ funds, display no or very limited return similarities. Furthermore, we also find evidence of fund managers performing undisclosed changes of their trading style over time. Those funds that misclassified themselves once are particularly likely to change their trading style again. Although style self‐declaration can, therefore, be quite misleading, our results indicate that hedge funds do not misdeclare their style strategically to improve their relative performance.

Foreign exchange trading is performed in opaque and decentralized markets. The two-tier market structure consisting of a customer segment and an interdealer segment to which only market makers have access gives rise to the possibility of price discrimination. We develop a theoretical pricing model that accounts for market-power considerations and analyze a database of the trades of a foreign exchange market maker. We find that the market maker generally exerts low bargaining power vis-á-vis customers. The dealer earns lower average spreads on trades with financial customers than commercial customers, even though the former are perceived to convey exchange-rate-relevant information.  相似文献

We show that highly liquid Exchange‐Traded Funds (ETFs), especially those that are more liquid than their underlying basket of securities (i.e., positive relative liquidity), are particularly attractive to investors. Using three definitions of liquidity, we find that relative liquidity predicts net fund flows, as well as inflows and outflows positively and significantly. We further document a liquidity clientele among institutional investors: (i) relative liquidity is significantly more important for short‐ than for long‐term investors; and (ii) relative liquidity is inversely related to investors’ average holding duration in the ETFs. These two findings provide evidence that relative liquidity encourages short‐term demand.  相似文献

Anecdotal evidence suggests and recent theoretical models argue that past stock returns affect subsequent stock trading volume. We study 3,000 individual investors over a 51 month period to test this apparent link between past returns and volume using several different panel regression models (linear panel regressions, negative binomial panel regressions, Tobit panel regressions). We find that both past market returns as well as past portfolio returns affect trading activity of individual investors (as measured by stock portfolio turnover, the number of stock transactions, and the propensity to trade stocks in a given month). After high portfolio returns, investors buy high risk stocks and reduce the number of stocks in their portfolio. High past market returns do not lead to higher risk taking or underdiversification. We argue that the only explanations for our findings are overconfidence theories based on biased self-attribution and differences of opinion explanations for high levels of trading activity.  相似文献
