The financial revolution improved the British government's ability to borrow, and thus its ability to wage war. North and Weingast argued that it also permitted private parties to borrow more cheaply and widely. We test these inferences with evidence from a London bank. We confirm that private bank credit was cheap in the early eighteenth century, but we argue that it was not available widely. Importantly, the government reduced the usury rate in 1714, sharply reducing the circle of private clients that could be served profitably. 相似文献

We empirically investigate the interactions among hedging, financing, and investment decisions. We argue that the way in which hedging affects a firm's financing and investing decisions differs for firms with different growth opportunities. We find that high growth firms increase their investment, but not leverage, by hedging. However, we also find that firms with few investment opportunities use derivatives to increase their leverage. 相似文献

In this article we study a very simple trial and error learning process in the context of a Cournot oligopoly. Without any knowledge of the payoff functions players increase, respectively decrease, their quantity as long as this leads to higher profits. We show that despite the absence of any coordination or punishing device this process converges to the joint‐profit‐maximizing outcome. 相似文献

The margin system is the first line of defense against the default risk of a clearinghouse. From the perspectives of a clearinghouse, the utmost concern is to have a prudential system to control the default exposure. Once the level of prudentiality is set, the next concern will be the opportunity cost of the investors, because high opportunity cost discourages people from hedging futures, and thus defeats the function of a futures market. In this article, we first develop different measures of prudentiality and opportunity cost. We then formulate a statistical framework to evaluate different margin‐setting methodologies, all of which strike a balance between prudentiality and opportunity cost. Three margin‐setting methodologies, namely, (1) using simple moving averages; (2) using exponentially weighted moving averages; (3) using a GARCH approach, are applied to the Hang Seng Index futures. Keeping the same prudentiality level, it is shown that the one using a GARCH approach by and large gives the lowest average overcharge. © 2004 Wiley Periodicals, Inc.

This article uses a nonparametric test based on the arc‐sine law (see, e.g., Feller, 1965 ), which involves comparing the theoretical distribution implied by an intraday random walk with the empirical frequency distribution of the daily high/low times, in order to address the question of whether the abandonment of pit trading has been associated with greater market efficiency. If market inefficiencies result from flaws in the market microstructure of pit trading, they ought to have been eliminated by the introduction of screen trading. If, on the other hand, the inefficiencies are a reflection of investor psychology, they are likely to have survived, unaffected by the changeover. We focus here on four cases. Both the FTSE‐100 and CAC‐40 index futures contracts were originally traded by open outcry and have moved over to electronic trading in recent years, so that we are able to compare pricing behavior before and after the changeover. The equivalent contracts in Germany and Korea, on the other hand, have been traded electronically ever since their inception. Our results overwhelmingly reject the random‐walk hypothesis both for open‐outcry and electronic‐trading data sets, suggesting there has been no increase in efficiency as a result of the introduction of screen trading. One possible explanation consistent with our results would be that the index futures market is characterized by intraday overreaction. © 2004 Wiley Periodicals, Inc.

This article analyzes the effects of the length of hedging horizon on the optimal hedge ratio and hedging effectiveness using 9 different hedging horizons and 25 different commodities. We discuss the concept of short‐ and long‐run hedge ratios and propose a technique to simultaneously estimate them. The empirical results indicate that the short‐run hedge ratios are significantly less than 1 and increase with the length of hedging horizon. We also find that hedging effectiveness increases with the length of hedging horizon. However, the long‐run hedge ratio is found to be close to the naïve hedge ratio of unity. This implies that, if the hedging horizon is long, then the naïve hedge ratio is close to the optimum hedge ratio. © 2004 Wiley Periodicals, Inc. Jrl Fut Mark 24:359–386, 2004 相似文献

Research on ethnic residential patterns is overwhelmingly empiricist in focus. The discursive context surrounding the socio‐spatial phenomenon needs to be acknowledged since it can have concrete impacts on the practice of urban social planning as well as the spatial behaviour of individuals and groups. Using Henri Lefebvre's insights into the production of social space, this article looks at how a dominant representation of space is constructed, with its implications for ‘lived’ spaces and the spatial practices which circumscribe them. The case of Singapore is examined, where the government has appropriated the discourse surrounding ‘ethnic regrouping’ in an attempt to legitimize the unpopular policy of ethnic quotas in public housing. Alleging that ‘ethnic regrouping’ had been taking place during the 1980s, this was portrayed as undesirable and contrary to the ideal of integration. The imposition of ethnic quotas was thus justified as necessary and appropriate. Systematic analysis using the index of dissimilarity, however, problematizes this representation of space. The rhetoric surrounding ethnic regrouping is revealed to be a means of social discipline whereby the government imposes a particular representation of space and seeks to manipulate the social landscape via technocratic means. Les recherches sur les modèles résidentiels ethniques débordent d'empirisme. Or, le contexte discursif du phénomène socio‐spatial doit être reconnu puisque celui‐ci peut avoir des incidences tangibles sur l'exercice de l'urbanisme social, ainsi que sur le comportement des individus et groupes dans l'espace. A partir des idées d'Henri Lefebvre sur la production de l'espace social, l'article analyse comment s'élabore une représentation dominante de l'espace, avec ses implications sur les espaces ‘vécus'et les pratiques spatiales qui les délimitent. Dans le cas de Singapour, le gouvernement s'est approprié le discours autour du ‘regroupement ethnique’ dans le but de légitimer la politique impopulaire des quotas ethniques dans les logements publics. Sous le prétexte que le ‘regroupement ethnique’ s'était déroulé dans les années 1980, il a été présenté comme indésirable et contraire à l'idéal d'intégration. Les quotas ethniques ont donc été justifiés comme nécessaires et pertinents. Cependant, une analyse systématique utilisant l'indice de dissemblance remet en cause cette représentation de l'espace. La rhétorique entourant le regroupement ethnique apparaît comme un outil de discipline sociale grâce auquel le gouvernement impose une représentation particulière de l'espace, cherchant à manipuler le paysage social par des moyens technocratiques. 相似文献

Structural vector autoregressive (SVAR) models have emerged as a dominant research strategy in empirical macroeconomics, but suffer from the large number of parameters employed and the resulting estimation uncertainty associated with their impulse responses. In this paper, we propose general‐to‐specific (Gets) model selection procedures to overcome these limitations. It is shown that single‐equation procedures are generally efficient for the reduction of recursive SVAR models. The small‐sample properties of the proposed reduction procedure (as implemented using PcGets) are evaluated in a realistic Monte Carlo experiment. The impulse responses generated by the selected SVAR are found to be more precise and accurate than those of the unrestricted VAR. The proposed reduction strategy is then applied to the US monetary system considered by Christiano, Eichenbaum and Evans (Review of Economics and Statistics, Vol. 78, pp. 16–34, 1996) . The results are consistent with the Monte Carlo and question the validity of the impulse responses generated by the full system. 相似文献
