Fine‐Tuning a Corporate Hedging Portfolio: The Case of an Airline

Industrial companies typically face a multitude of risks that could cause significant fluctuations in their cash flow. This is a case study of the hedging strategy adopted by an international air carrier to manage its jet‐fuel price exposure. The airline's hedging approach uses “strips” of monthly collars constructed with Asian options whose payoffs are based on average of “within‐prompt‐month” oil prices. Using the carrier's own implicit objective function based on an annual granularity, the authors show how the air carrier could fine‐tune its current hedge portfolio by adding tailored exotic options. The article describes annual average‐price options, provides an explicit valuation of them, and considers how such instruments may affect corporate liquidity. Consistent with its annual objective function, the airline made this exotic derivative the central tool to hedge across all potential realized values of annual jet‐fuel spot prices. The authors believe this modified portfolio is better suited to address the firm's hedging cost and its overall exposure to jet‐fuel price fluctuations.

The Structure and Growth of the Credit Union Industry in the United states: Meeting Challenges of the Market

A bstract . Credit Unions in the United States have grown significantly in recent years. This paper identifies and analyzes the unique characteristics of the credit union industry contributing to this growth. The consolidation of smaller institutions and product diversification among larger credit unions in the environment of financial deregulation in recent years has resulted in enhanced services for credit union members. The industry is expected to continue its growth in membership and assets relative to other depository intermediaries.     

Linear and nonlinear dynamic relationships between housing prices and trading volumes

This study applied linear and nonlinear causality tests and estimation models to investigate the efficiency of housing prices and volumes in the United States and its four major regions. The results of this study confirm that housing volumes can function as a price-discovery indicator. According to the nonlinear volatility of housing prices, this study verified numerous hypotheses. Housing returns can also influence housing volume. The results of this study imply that housing price efficiency can vary based on market conditions. Consequently, estimating the behavior of housing prices through a linear model can result in underestimating the information reflected by housing returns.     

Technological heterogeneity and corporate investment

We propose an importance-sampling procedure to improve the computational performance of the simulated method of moments (SMM) for the estimation of structural models with fixed parameter heterogeneity. The main advantage of the procedure is that it does not require to simulate observations every time that the structural parameters change during the minimization of the SMM criterion function. We illustrate the use of our method by estimating a neoclassical model of investment for a sample of US manufacturing companies, allowing the technological parameters to vary across firms.     

What drives returns to euro area housing? Evidence from a dynamic dividend–discount model

We apply a dynamic dividend–discount model to analyse housing returns for eight euro area countries comprising over 90% of euro area GDP, both individually and as a panel. A vector autoregressive model (VAR) is estimated for four variables – excess return to housing, rents, the real interest rate and real disposable per capita income – using quarterly data over the period 1978–2009. This empirical investigation – which allows for a decomposition of house price movements into movements in rent (cash-flow) and expected return news components – indicates that the bulk of the variability of euro area house price movements can be attributed to movements in fundamentals. There remains nonetheless an important but less sizeable influence of market-wide (or expected-return) variations in house prices. Country-specific estimation indicates considerable heterogeneity around the euro area result, both for what concerns long-term impacts and dynamics. Notably, changes in expected returns play a relatively strong role in the house prices of Ireland and Spain.     

The Implied Longevity Yield: A Note on Developing an Index for Life Annuities

I develop an index for tracking the dynamic behavior of life (pension) annuity payouts over time, based on the concept of self‐annuitization. Our implied longevity yield (ILY) value is defined equal to the internal rate of return (IRR) over a fixed deferral period that an individual would have to earn on their investable wealth if they decided to self‐annuitize using a systematic withdrawal plan. A larger ILY number indicates a greater relative benefit from immediate annuitization. I use age 65—with a 10‐year period certain—compared against the same annuity at age 75 as the standard benchmark for the index, and calibrate to a comprehensive time series of weekly (Canadian) life annuity quotes from 2000 through 2004. I find that during this period the ILY varied from 5.45 percent to 6.90 percent for males and from 5.00 percent to 6.42 percent for females and was highly correlated with a duration‐weighted average yield of 10‐year and long‐term Government of Canada bonds. I believe our ILY metric can help promote and explain the benefits of acquiring lifetime payout annuities by translating the abstract‐sounding longevity insurance into more concrete and measurable financial rates of return.     

Environmental Finance: Innovating to Save the Planet*

This article demonstrates that it is not only possible, but urgently necessary, to apply principles of finance and economics—efficient use of scarce capital, price transparency, and lowered transaction costs—to environmental issues. From limiting acid rain with the sulfur dioxide‐allowance market to the implementation of the Clean Water Act, market‐based solutions have proven consistently more effective in protecting the environment than government regulation alone. Project financing, public‐private partnerships, and tradable permits have come to supplement or replace conventional command‐and‐control regulation and purely tax‐based instruments. Tradable permit systems have been deployed to phase down use of leaded gasoline, end the use of ozone‐depleting chloro‐fluorocarbons, and even reduce air pollution in the smoggy skies above Los Angeles. And the United Nations Environment Program has launched a Finance Initiative as a formal means of mobilizing the financial sector to take a more active role in protecting the environment. Such an approach can minimize the aggregate costs of achieving environmental targets while providing dynamic incentives for the adoption and diffusion of greener technologies.     

会计变革与经济效率：基于会计思想史的角度

财务会计是确定企业经济效益的工具。在企业外部,通过财务会计提供的企业利润信息,借助资本逐利天性,引导投资者的理性决策,客观上"自发地"实现社会资源的配置效率。在企业内部,经营者通过会计提供的利润信息,决策并引导资源在产品之间的有效率配置和有效率生产。因此,会计就是一个服务于提高经济效率的工具。当一个时期的会计能够满足实现提高经济效率的需要,它就对经济发展起促进作用;反之则会扭曲资源配置,阻碍经济发展。会计确定企业利润的方法,一定要与不同时期经济发展状况相适应,以满足合理引导资源配置、提高经济效率的需要,这是促进会计变革的根本动力。功利性利用会计未尝不可,但如何成功地功利性利用会计,是一个需要继续研究的问题。
