The Effect of the Hedge Horizon on Optimal Hedge Size and Effectiveness When Prices are Cointegrated
This study compares two alternative regression specifications for sizing hedge positions and measuring hedge effectiveness: a simple regression on price changes and an error correction model (ECM). We show that, when the prices of the hedged item and the hedging instrument are cointegrated, both specifications yield similar results which depend on the hedge horizon (i.e., the time frame for measuring price changes). In particular, the estimated hedge ratio and regression R2 will both be small when price changes are measured over short intervals, but as the hedge horizon is lengthened both measures will converge toward one. These results imply that, when prices are cointegrated, a longer hedge horizon will yield an optimal hedge ratio closer to one, while at the same time enhancing the ability to qualify for hedge accounting. © 2011 Wiley Periodicals, Inc.

This paper analyzes the effects of regulatory uncertainty regarding labor costs on investment in a liberalized market. We distinguish between the external investment margin (market entry) and the internal investment margin (technology), and establish that regulatory uncertainty affects these margins differently, encouraging market entry, but discouraging technological investment. As a consequence, the impact of regulatory uncertainty on competition in liberalized markets is a combination of these two countervailing forces. 相似文献

This paper analyzes a multinational corporation that may use tax evasion and profit shifting as a means to minimize tax liabilities. Our main finding is that profit shifting may occur even when tax rates are the same across countries. This will be the case whenever there is a tax differential in effective tax rates resulting from differences in tax enforcement. In this context, profit shifting occurs to enable tax evasion in a country where tax enforcement is less harsh. Moreover, for a given differential in tax rates, differences in tax enforcement may either accentuate or dampen profit shifting. Importantly, the predictions regarding the direction of profit shifting that would result in our set-up may contrast sharply with those of the preceding literature. 相似文献

We build on our earlier model of money in which bank liabilities circulate as a medium of exchange. We investigate optimal bank behavior and the resulting provision of liquidity under a range of central bank regulations. In our model, banks issue inside money under fractional reserves, facing the possibility of excess redemptions. Banks consider the float resulting from money creation and make reserve‐management decisions that affect aggregate liquidity conditions. Numerical examples demonstrate positive bank failure rates when returns to banking are low. Central bank interventions may improve banks' returns and welfare through a reduction in bank failure. 相似文献

Mega‐sporting events such as the Fédération Internationale de Football Association (FIFA) World Cup are expensive affairs. Host countries often justify the spending required to stage these events by predicting that mega‐events will draw large numbers of tourists. This paper analyzes monthly foreign tourist arrivals into Brazil between 2003 and 2015 and finds that the 2014 FIFA World Cup increased foreign tourism by roughly 1 million visitors. This number far exceeded expectations, but we show that roughly a quarter of this increase in foreign tourism was caused by the fortuitous advancement of Argentina's national team, and potential hosts should not count on the event to consistently produce out‐sized tourism figures. We conclude that on‐field results can greatly influence FIFA World Cup tourism. (JEL L83, F14) 相似文献

美国政府正在对美国几家世界顶尖的金融机构采取刑事调查。高盛有罪与否?我看高盛是做了令人厌恶的事情,但它的行为并不违法。我们赞同高盛,因为高盛发展了抵押业务,并将其设计成对冲基金中最赚钱的“噱头”。其次,高盛人也清楚,投资基金可能会给投资者带来巨大的损失。其实,高盛赢在其战略,它将盈利用在了冲抵投资的失败。 相似文献

We analyze bureaucracy and corruption in a market with decentralized exchange and “lemons.” Exchange is modeled as a sequence of bilateral, random matches. Agents have private information about the quality of goods they produce and can supplement trade with socially inefficient bribes. Bureaucracy is modeled as a group of agents who enjoy centralized production and consumption. Transaction patterns between the bureaucracy and the private sector are fully endogenous. Centralized production and consumption in the bureaucracy give rise to low power incentives for the individual bureaucrats. As a result, private agents might bribe bureaucrats, whereas they do not bribe each other. An equilibrium with corruption and an equilibrium without corruption can coexist. We discuss some welfare implications of the model. 相似文献

In active investment climates where firms sequentially improve each other's products, a patent can terminate either because it expires or because a non-infringing innovation displaces its product in the market. We define the length of time until one of these happens as the effective patent life, and show how it depends on patent breadth. We distinguish lagging breadth, which protects against imitation, from leading breadth, which protects against new improved products. We compare two types of patent policy with leading breadth: (1) patents are finite but very broad, so that the effective life of a patent coincides with its statutory life, and (2) patents are long but narrow, so that the effective life of a patent ends when a better product replaces it. The former policy improves the diffusion of new products, but the latter has lower R&D costs. 相似文献

A research project was undertaken within a multi‐county region in southeastern Ohio to ascertain the attitudes of local residents toward future outdoor recreation development within the area. A systematic random sample of 1493 respondents was drawn from a five‐county region to test a theoretical perspective developed from selected components of social exchange theory. The findings demonstrated that the respondents held very favorable attitudes toward outdoor recreation development. Multivariate analysis of the data revealed that the theoretical model was basically supported. The findings are discussed from both applied and theoretical perspectives. 相似文献
