Jackson and Kaserman (1991) model diffusion of an innovation an investment decision where the time of adoption is motivated by cost-minimization. This paper tests this model, using the adoption by American major airlines of jet aircraft embodying high bypass turbojet engine technology.The results support the Jackson-Kaserman model. The effect of aircraft age has the appropriate and significant sign. Likewise, average stage length measuring relative variable cost performance of the old and new technology is appropriately signed. 相似文献

Prior research has shown that pro-forma (recurring operating) earnings reported by managers and analysts are more value relevant than GAAP net income. Since GAAP net income contains many non-operating items that reduce its value relevance compared to operating earnings, comparing the value relevance of GAAP net income with operating earnings unduly favors operating earnings. We show that operating earnings reported by managers and analysts are more value relevant than a measure of operating earnings derived from firms' financial statements, as reported by Standard and Poor's. Our evidence is important because it indicates that operating earnings reported by managers and analysts contain value relevant information beyond that provided by operating earnings obtained by sophisticated users from firms' financial statements. 相似文献

Time pacing: competing in markets that won't stand still 总被引:6,自引:0,他引:6
Most companies change in reaction to events such as moves by the competition, shifts in technology, or new customer demands. In fairly stable markets, "event pacing" is an effective way to deal with change. But successful companies in rapidly changing, intensely competitive industries take a different approach. They change proactively, through regular deadlines. The authors call this strategy time pacing. Like a metronome, time pacing creates a rhythm to which managers can synchronize the speed and intensity of their efforts. For example, 3M dictates that 25% of its revenues every year will come from new products, Netscape introduces a new product about every six months, and Intel adds a new fabrication facility to its operations approximately every nine months. Time pacing creates a relentless sense of urgency around meeting deadlines and concentrates people on a common set of goals. Its predictability also provides people with a sense of control in otherwise chaotic markets. The authors show how companies such as Banc One, Cisco Systems, Dell Computer, Emerson Electric, Gillette, Intel, Netscape, Shiseido, and Sony implement the two essentials of time pacing. The first is managing transitions--the shift, for example, from one new-product-development project to the next. The second is setting the right rhythm for change. Companies that march to the rhythm of time pacing build momentum, and companies that effectively manage transitions sustain that momentum without missing important beats. 相似文献

Measurement effects and the variance of returns after stock splits and stock dividends 总被引:2,自引:0,他引:2
This article examines the relation between two factors affectingstock returns, the bid-ask spread and price discreteness, andthe increase in return variance after ex-dates of stock splitsand stock dividends. Controlling for these effects, the varianceof daily returns still increases significantly. The varianceof weekly returns also increases significantly, and the varianceof returns for a control sample of nonsplitting firms showsno significant increase. Variance ratio tests show that bid-askerrors are small for these stocks and therefore cannot explainthe large increase in variance. Spreads and price discretenessdo not explain increased variance after stock distributions. 相似文献

Ranking Accounting Ph.D. Programs and Faculties Using Social Science Research Network Downloads 总被引:1,自引:1,他引:1
Brown Lawrence D. Laksmana Indrarini 《Review of Quantitative Finance and Accounting》2004,22(3):249-266
We rank accounting Ph.D. programs and accounting faculties based on downloads individuals' working papers posted to the Social Science Research Network (SSRN) receive. We retain 185 individuals included in Accounting Faculty Directory 2002–2003 (Hasselback, 2002) whose work has been most heavily downloaded as of August 21, 2002. We rank Ph.D. programs (faculties) both adjusting and not adjusting for program (faculty) size. We provide rankings both without regards to when individuals graduated and for individuals graduating during three consecutive sub-periods: pre-1982, 1982–1991 and 1992–2001. We first provide rankings without regards to teaching or research area. After dichotomizing individuals into those whose teaching/research area is financial versus non-financial we provide additional rankings focusing on non-financial research areas. 相似文献

A Temporal Analysis of Earnings Surprises: Profits versus Losses 总被引:11,自引:1,他引:11
Lawrence D. Brown 《Journal of Accounting Research》2001,39(2):221-241
I show that median earnings surprise has shifted rightward from small negative (miss analyst estimates by a small amount) to zero (meet analyst estimates exactly) to small positive (beat analyst estimates by a small amount) during the 16 years, 1984 to 1999. I show that a rightward temporal shift in median surprise from negative to positive describes earnings, but neither profits nor losses. Median profit surprise shifts within the positive quadrant, from zero to one cent per share. Median loss surprise shifts within the negative quadrant from extreme negative (about -33 cents per share) to zero. I show that the median surprise for profits exceeds that for losses in every year. I document significant positive temporal trends in both meet and beat analyst estimates for both profits and losses, but I find a greater frequency of profits that either meet or beat analyst estimates in every year. I find a significant positive temporal trend in positive profits that are "a little bit of good news," and a significant negative temporal trend in managers who report losses that are an "extreme amount of bad news." My results are robust to the four internal validity threats I consider—namely temporal changes in: (1) analyst forecast accuracy, (2) the mix of earnings of one sign preceded by earnings of another sign four quarters ago, (3) the timeliness of the most recent analyst forecast, and (4) the I/B/E/S definition of actual earnings. I find that managers of growth firms are relatively more likely than managers of value firms to report good news profits. I show that when they do report positive profit surprises, managers of growth firms are more likely to report "a little bit of good news" in every year. 相似文献
