城市轨道交通作为城市综合交通体系的重要组成部分,其站间距的设置与客流吸引能力、旅客出行时间、列车运行效率等因素密切相关。通过分析城市轨道交通站间距设置的影响因素,提出合理站间距的设置方法及优化模型,结合实例计算并综合考虑各方面因素,推荐城市中心区车站的合理站间距以1050～1 150 m为最优,郊区车站的合理站间距以1 800 m左右为优。 相似文献

This paper studies the optimal dividend strategies of an insurance company when the manager has time-inconsistent preferences. We consider the problem for a naive manager and a sophisticated manager, and analytically derive the optimal dividend strategies when claim sizes follow an exponential distribution. Our results show that the manager with time-inconsistent preferences tends to pay out dividends earlier than her time-consistent counterpart and that the sophisticated manager is more inclined to pay out dividends than the naive manager. Furthermore, we extend these results to the case with claim sizes following a mixed exponential distribution, and provide a numerical analysis to reveal the sensitivity of the optimal dividend strategies to changes in the premium, claims and surplus volatility. 相似文献

我国上市公司年报与第一季报的披露时间底线同为4月30号,存在上市公司年报与第一季报披露时间间隔异常的现象,本文以2004年至2008年第一季度连续存在的上市公司为样本,比较分析了年报与第一季报披露时间间隔在一周之内的上市公司,与披露时间间隔在一周之外的上市公司的盈利水平和盈利质量。结果表明,年报与第一季报披露时间间隔异常的上市公司的盈利水平和盈利质量都显著低于其他上市公司,并对这类上市公司的监管和投资策略提出了建议。 相似文献

This study examines the quantitative properties of optimal sustainable monetary policies using a monetary model with a stabilization bias. As in Kurozumi (2008), the optimal sustainable policy is a strategy considered in the absence of commitment technologies; however it is implemented following an optimal quasi-sustainable policy derived by assuming that the commitment technologies are present. This study finds that solving for the policy function of the optimal quasi-sustainable policy yields a result basically identical to the Ramsey-optimal commitment policy under a set of parameters commonly used in the literature. The simulation shows two further results: policymakers have incentive to deviate from the Ramsey-optimal commitment policy when the lagged output gap is large and the optimal quasi-sustainable policy endogenously diminishes the steadfastness of policymakers׳ commitment. 相似文献

Many environmental problems are due to damage caused by pollutants that accumulate with a time lag following their emission. In this study, we focus on nitrates used in agriculture, which can pollute groundwater many years after their initial application. A dynamic optimal control problem with heterogeneous farmers is proposed. The usual structural parameters such as the discount rate, the natural clearing rate and the lagged time interval between the occurrence of soil‐level pollution and the impact on groundwater are taken into account. We also examine pollution as caused by a continuous set of farms characterised by their individual performance index and by their individual marginal contribution to the pollution. The issue is further investigated by taking account of change in the information context, successively related to perfect information and to asymmetric information. As a result, when the delay between the spreading of N‐fertilizer and the impact on the aquifer increases, that is, the longer the lag, the steady‐state pollution stock and the steady‐state shadow price of the stock both increase. Moreover, we show that the optimal regulation may require a decreasing amount of fertilizer over time, even in the case of initial underpollution. 相似文献

Economic theory considers physical production characteristics and related property rights as key determinants of the organization of an industry. Yet, we frequently observe coexisting governance modes within industries and firms, even when the transaction attributes of a commodity are homogenous. We test whether risk and time preferences, price expectations, and trust in supply chain types can explain variations and coexistence in governance. Specifically, we experimentally elicit economic preferences of forest managers in the Swiss wood sector. We find that all behavioral dimensions are related to the choice of sales channel. Most importantly, trust and expectations are key determinants in transferring property rights, while risk aversion, patience, and ownership structure explain the existence of plural forms at the firm level. 相似文献

By comparing liquidity and price discovery effects, the market microstructure literature insists that in‐the‐money options (ITMs) are informationally inferior to out‐of‐the‐money options. However, such an argument is at odds with the anecdotal point that ITMs may be more effective for hedging future volatility risk. ITMs are driven by institutional investors, who are considered to be informed traders, and can provide significant hedging benefits such that a hedging with ITMs requires fewer options and less frequent rebalancing. To clear this suspicion, we compare implied risk‐neutral densities, implied risk aversions and volatility forecasting performances. Contrary to the anecdotal evidence, our findings show the inferiority of ITMs in forecasting future volatilities, even after adjusting for the risk attitude of investors. These findings offer support for the arguments made in the extant market microstructure literature. 相似文献
