Is the Short Rate Drift Actually Nonlinear? 总被引:7,自引:0,他引:7
Aït-Sahalia (1996) and Stanton (1997) use nonparametric estimators applied to short-term interest rate data to conclude that the drift function contains important nonlinearities. We study the finite-sample properties of their estimators by applying them to simulated sample paths of a square-root diffusion. Although the drift function is linear, both estimators suggest nonlinearities of the type and magnitude reported in Aït-Sahalia (1996) and Stanton (1997). Combined with the results of a weighted least squares estimator, this evidence implies that nonlinearity of the short rate drift is not a robust stylized fact. 相似文献

Bondholder Wealth Effects in Mergers and Acquisitions: New Evidence from the 1980s and 1990s 总被引:3,自引:0,他引:3
We examine the wealth effects of mergers and acquisitions on target and acquiring firm bondholders in the 1980s and 1990s. Consistent with a coinsurance effect, below investment grade target bonds earn significantly positive announcement period returns. By contrast, acquiring firm bonds earn negative announcement period returns. Additionally, target bonds have significantly larger returns when the target's rating is below the acquirer's, when the combination is anticipated to decrease target risk or leverage, and when the target's maturity is shorter than the acquirer's. Finally, we find that target and acquirer announcement period bond returns are significantly larger in the 1990s. 相似文献

Abstract: We examine the marginal choice between debt and equity securities using a factor analytic approach. This data reduction property eliminates the need to select the one best variable to proxy for a particular theoretical construct. Our results reinforce numerous existing findings using traditional methods and suggest both static tradeoff and asymmetric information based considerations are relevant in determining security choice. Two new results are presented related to the accounting liquidity of the firm. First, the preference for equity is increasing with liquidity as suggested by the window of opportunity hypothesis. Secondly, the market response to equity issuance announcements is inversely related to the liquidity of the firm. Profitability and growth measures support Jensen's (1986) agency cost of free cash flow as a potential explanation for the second finding. 相似文献

An alternative theoretical approach to the analysis for dichotomous causal systems that involve probabilistic causation, the conditional probability approach, has recently been explicated. It was shown that there exist various composition and decomposition rules for analyzing various kinds of general causal systems, and an important distinction between pure-“or”-and pure-“and”-causal systems was explicated. In this paper these earlier results are used to analyze a causal system which has been studied by J.A. Davis (1976), who uses his linear flow graph approach to analysis. The results of the conditional probability approach are compared to the linear flow graph, and it is shown that the two approaches lead to strikingly different results. 相似文献

This study tests the application of the Ho and Saunders (1981) model of bank net interest margins (NIMs), and its subsequent developments, using Australian data. The core elements of this model apply in Australia. Bank market power is found to increase NIMs, consistent with McShane and Sharpe (1985) , with evidence of bank buying market share and mispricing for risk. Operating costs also have an important role in determining NIMs, together with implied payments and management quality. Bank NIMs are found to have fallen over the study period. 相似文献

This paper examines whether there is increased inter-year instability in food consumption at the national level, and to what extent this is attributable to increased instability of food production in the wake of adoption of modern agricultural technology. The data analysed indicates that increased production instability does translate into increased fluctuations in consumption. Nevertheless, year-to-year consumption variability among the sample of 38 countries has declined during the past 25 years. This is attributed to improved stocking operations and trade practices which accompany economic growth. Nevertheless, food insecurity, as measured in terms of fluctuations around trend levels of consumption, does remain a problem, especially among the poor. Therefore, policy options to reduce consumption instability are outlined. 相似文献

说迪士尼仅仅是像嘉年华那样的游乐企业,一定没有看到游乐园在香港、东京的巨亏,在巴黎的那家分店还因为经营不善倒闭了。迪士尼本质上,还是一家媒体公司,每年从《玩具总动员》这样的影视产品大获其利,顺带还卖点同品牌的童装。 相似文献
