This paper utilizes the concept of aggregative consistency defined in Rubinstein and Fishburn [1986], and the FASB's concept of representational faithfulness to evaluate foreign currency translation and accounting for changing prices as embodied in SFAS 70. The paper shows that SFAS 70 produces measurement errors and creates a foreign currency translation adjustment which does not reflect the effects of exchange rate changes. The conditions defined in the paper also facilitate an evaluation of the relative merits of restate/translate and translate/restate.

This paper is motivated by two facts: failure of log-linear empirical exchange rate models of the 1970's and the observed variability of risk premiums in the forward market. Rational maximizing models predict that changes in conditional variances of monetary policies, government spendings, and income growths affect risk premiums and induce conditional volatility of exchange rates.

Trading on private information creates inefficiencies because there is less than optimal risk sharing. This occurs because the response of market makers to the existence of traders with private information is to reduce the liquidity of the market. The institution of the monopolist specialist may ease this inefficiency somewhat by increasing the liquidity of the market. While competing market makers will expect a zero profit on every trade, the monopolist will average his profits across trades. This implies a more liquid market when there is extensive trading on private information.

This paper describes efforts to validate a multiple car dispatch queueing (MCD) model of police patrol operations using New York City data. The MCD model was designed for use in a computer system that has been disseminated to many police departments in the U.S. to help planners allocate patrol cars among precincts. It has also been used to evalute specific changes in patrol policy in New York. We define validation as a series of hierarchical procedures ranging from tests of mathematical correctness to evaluations of model robustness.

This article looks at the alternative methods that can be employed by firms with regards to rewarding equity holders. Economists have long been puzzled by why firms pay dividends when alternative methods of rewarding shareholders and financiers exist which involve less taxes. Dividend paying equity appears to be the most heavily taxed capital instrument available. It is subject to two levels of taxation: first, the federal corporation income tax (set at a 34 percent marginal rate in the U.S. as of June 1989) and second, the personal income tax if the shares are owned by households.

Analyzing the location choices of the post-1964 U.S.

Patterns of optical flow produced at the eye of a moving observer are important for the guidance of locomotion. This study examined age-related changes in the ability to perceive one's direction of self-motion, or heading, from optical flow, using computer displays that simulate translational or curvilinear movement parallel to a random-dot ground surface.
