In this article, we examine the order of integration of the U.S. long-term interest rate by means of using fractionally integrated techniques. Using annual data for the time period 1940-2000, the results based on the univariate tests of Robinson [Journal of American Statistical Association 84 (1994) 1420] support the hypothesis of a unit root. However, using a much longer span of the data (1798-2000), the order of integration seems to be smaller than one if the disturbances are white noise, while the unit root cannot be rejected if they are weakly autocorrelated.  相似文献

In this paper we provide an overview of empirical data relating to the use, scale and cost of executive options schemes in Australia. Our data is based on a sample of 100 large listed Australian corporations. Our data suggests that approximately 80% of large listed corporations in Australia presently employ executive options schemes, but that the size and cost of these schemes reduced significantly after 2000. We argue that this reflects the impact of increased public scrutiny over options schemes and the impending move in Australia towards a financial reporting regime in which treating the cost of options as an expense for the purposes of calculating annual profit and loss is mandatory.  相似文献

This letter is a discussion of the application of the pitch template developed by Faff (2015) to a financial accounting research topic. The pitch template focuses ideas into key areas, giving clear and concise direction in planning and structuring the research idea. In this instance, the template is used in a nonlinear manner to develop a research proposal to investigate the relation between cash bonus payments and firm financial performance.  相似文献

Option prices vary with not only the underlying asset price, but also volatilities and higher moments. In this paper, we use a portfolio of options to seclude the value change of the portfolio from the impact of volatility and higher moments. We apply this portfolio approach to the price discovery analysis in the U.S. stock and stock options markets. We find that the price discovery on the directional movement of the stock price mainly occurs in the stock market, more so now than before as an increasing proportion of options market makers adopt automated quoting algorithms. Nevertheless, the options market becomes more informative during periods of significant options trading activities. The informativeness of the options quotes increases further when the options trading activity generates net sell or buy pressure on the underlying stock price, even more so when the pressure is consistent with deviations between the stock and the options market quotes.

Accounting standards require companies to assess the fair value of any stock options granted to executives and employees. We develop a model for accurately valuing executive and employee stock options, focusing on performance hurdles, early exercise and uncertain volatility. We apply the model in two case studies and show that properly computed fair values can be significantly lower than traditional Black–Scholes values. We then explore the implications for pay-for-performance sensitivity and the design of effective share-based incentive schemes. We find that performance hurdles can require a much greater fraction of total compensation to be a fixed salary, if pre-existing incentive levels are to be maintained.  相似文献

We investigate how corporate payout policy is influenced by executive incentives, i.e. stock and option holdings, stock option deltas and stock-based pay-performance sensitivity for 1,650 publicly listed firms from the UK, Germany, France, Italy, the Netherlands and Spain, over the period from 2002 to 2009. Our results show that executive stock option holdings and stock option deltas are associated with lower dividend payments in our sample of European countries, where we do not observe any presence of dividend protection for executive stock options. We find that this relationship is mainly driven by exercisable stock options and by options that are in the money. Additionally, we observe that executive stock option holdings and stock option deltas have a negative impact on total payout, suggesting that executives do not substitute share repurchases for dividends. Furthermore, the fraction of share repurchases in total payout increases as executive stock option holdings and stock option deltas increase. Finally, our results show that executive share ownership and stock-based pay-performance sensitivity may mitigate agency conflicts by significantly increasing the level of total payout.  相似文献

In this paper, we test for the existence of long memory and structural breaks in the realized variance process for the DM/US$ and Yen/US$ exchange rates. While long memory is evident in the actual processes, a structural break analysis reveals that this feature is partially explained by unaccounted changes in regime. We then compare the forecasting performance of Markov switching models with that of an ARFIMA model. The results indicate that neglecting the break process is not important for very short term forecasting once it is allowed for a long memory component in the model, but that superior forecasts can be obtained at longer horizons by modelling both long memory and structural change.  相似文献

This study investigates the relation between discretionary accounting choices and executive compensation in Japanese firms. The results show that the use of discretionary accruals increases executive compensation. The analyses also show that firm managers receiving no bonus adopt income-decreasing accruals and extraordinary items. In particular, evidence shows that negative extraordinary items are strongly associated with no bonus payment. Finally, the research indicates that the association between discretionary accruals and executive bonus varies depending upon the circumstances of the firm. This study contributes to the literature on earnings management from an international comparative perspective since most previous studies on earnings management and executive compensation have focused on U.S. firms.  相似文献

This paper introduces the Smooth Transition version of FIGARCH model which is designed to account for both long memory and nonlinear dynamics in the conditional variance. Nonlinearity is introduced via a logistic transition function. The model can capture smooth changes in the volatility across different regimes as well as asymmetric response to negative and positive shocks and allows for nonzero thresholds. Simulations find that the Smooth Transition FIGARCH model outperforms the standard FIGARCH model when nonlinearity is present, and ignoring nonlinearity in the data may induce considerable costs in terms of bias and efficiency. Applications to exchange rate and stock market data show that the proposed model performs well both in-sample fit as well as in forecasting one-day ahead volatility.  相似文献

Data from 1,374 firms across four broad industrial groupings are used to assess the contribution that real (adaptation) options make to overall equity values. The analysis indicates that real (adaptation) options make a significant contribution to the equity value of firms with a market to book ratio (of equity) of around unity or less. As the market to book ratio grows beyond this level, however, the contribution made by real (adaptation) options decays quickly away and equity values are mainly comprised of the present value of the dividends that firms are expected to pay. This means that for around one in every five of the firms in our sample real (adaptation) options make a significant contribution to overall equity value. Thus, while linear equity valuation models would seem to be appropriate for the substantial majority of firms on which our sample is based, there is a sizeable minority of firms where real (adaptation) options have a significant impact on equity values. For this latter group of firms there will be a non-linear relationship between equity value and its determining variables. This has important implications for the regression procedures that are applied in this area of accounting research.  相似文献

This paper tests the effects of central bank intervention on the ex ante volatility of $/DM and $/yen exchange rates between 1985 and 1991. In contrast to previous research which employed GARCH estimates of conditional volatility, we estimate ex ante volatility using the implied volatilities of currency option prices. We also control for the effects of other macroeconomic announcements. We find little support for the hypothesis that central bank intervention decreases expected exchange rate volatility. Instead, central bank intervention is generally associated with a positive change in ex ante exchange rate volatility, or with no change.  相似文献

This paper provides empirical evidence on the long memory behavior of the stock markets of Egypt, Jordan, Morocco, and Turkey. To test for long memory in the returns and volatility, we employ the modified rescaled range statistic R/S proposed by Lo [Lo, A.W., 1991. Long-term memory in stock market prices. Econometrica 59, 1279–1313] and the recently proposed rescaled variance V/S statistic developed by Giraitis et al. [Giraitis, L., Kokoszka, P.S. Leipus, R., Teyssiere, G., 2003. Rescaled variance and related tests for long memory in volatility and levels. J. Econ. 112, 265–294]. Further analysis is conducted by employing the ARFIMA (p, d, q) model to estimate the long memory parameters. Egypt and Morocco show evidence of long memory in the return series, while Jordan and Turkey display negative persistence. For the volatility series, long memory is conclusively demonstrated for all markets. Then, we compare the forecasting performance of ARMA and ARFIMA models and find that the ARFIMA model outperforms in out-of-sample forecasting of the markets. Our results should be useful to regulators, practitioners and derivative market participants, whose success depends on the ability to forecast stock price movements in these markets.  相似文献

Implied standard deviation is widely believed to be the best available forecast of the volatility of returns over the remaining contract life (Jorion, 1995 ). In this paper, we take this result two steps further to the higher moments of the distribution (skewness and kurtosis) based on a Gram–Charlier series expansion of the normal distribution (Corrado and Su, 1996 ) using long-term CAC 40 option prices contract, named PXL. First, we found that implied first moments contain a substantial amount of information for future moments of CAC 40 returns although this amount decreases with respect to the moment's order. Secondly, we found that the different shapes of the volatility smile are consistent with different distribution of the underlying returns. Based on these results, we also observed that including other implied moments significantly improves the out-of-sample pricing performance of the Black–Scholes, (1973) model.  相似文献
