票据行为是一种法律行为,自然也可以以代理方式为之。民法上有关代理制度的规则一般也都可以适用于票据代理行为。但由于民法与商事法的立法旨趣各有侧重,为促进票据流通、保障交易安全,票据代理不能照搬民法上关于代理制度的规定。票据的无权代理是票据代理中一个非常典型的问题,与民法上的无权代理区别很大,其中存在的问题很多。对于票据的无权代理中是否应当赋予本人以追认权,多数大陆法系国家的立法例与英美法系国家之立法例有所不同。 相似文献

The mitigation hierarchy (MH) is a prominent tool to help businesses achieve no net loss or net gain outcomes for biodiversity. Technological innovations offer benefits for business biodiversity management, yet the range and continued evolution of technologies creates a complex landscape that can be difficult to navigate. Using literature review, online surveys, and semi-structured interviews, we assess technologies that can improve application of the MH. We identify six categories (mobile survey, fixed survey, remote sensing, blockchain, data analysis, and enabling technologies) with high feasibility and/or relevance to (i) aid direct implementation of mitigation measures and (ii) enhance biodiversity surveys and monitoring, which feed into the design of interventions including avoidance and minimization measures. At the interface between development and biodiversity impacts, opportunities lie in businesses investing in technologies, capitalizing on synergies between technology groups, collaborating with conservation organizations to enhance institutional capacity, and developing practical solutions suited for widespread use. 相似文献

Let X (r, n, m, k), 1 r n, denote generalized order statistics based on an absolutely continuous distribution function F. We characterize all distribution functions F for which the following linearity of regression holds
E(X(r+l,n,m,k) | X(r,n,m,k))=aX(r,n,m,k)+b.We show that only exponential, Pareto and power distributions satisfy this equation. Using this result one can obtain characterizations of exponential, Pareto and power distributions in terms of sequential order statistics, Pfeifers records and progressive type II censored order statistics.

Market impact is the link between the volume of a (large) order and the price move during and after the execution of this order. We show that in a quite general framework, under no‐arbitrage assumption, the market impact function can only be of power‐law type. Furthermore, we prove this implies that the macroscopic price is diffusive with rough volatility, with a one‐to‐one correspondence between the exponent of the impact function and the Hurst parameter of the volatility. Hence, we simply explain the universal rough behavior of the volatility as a consequence of the no‐arbitrage property. From a mathematical viewpoint, our study relies, in particular, on new results about hyper‐rough stochastic Volterra equations. 相似文献

A partir de datos del Panel de Hogares de la Unión Europea (PHOGUE) sobre Austria, España, Grecia, Irlanda, Italia y Portugal de 1995–2001 se examina la influencia de la discapacidad en el absentismo laboral utilizando tres variables: el estado de salud autoevaluado, el número de visitas al médico y el número de noches de ingreso en hospital. Según los resultados, el absentismo entre los trabajadores con discapacidad es mayor. La gravedad de la discapacidad también tiene influencia. El efecto total de la discapacidad en el absentismo representa un incremento marginal de entre 6 y 26 días de ausencia al año (dependiendo del país). 相似文献

This paper examines the use of go‐shop provisions in M&A. We find that go‐shop deals tend to have higher deal premiums and receive more competing bids while the length of the go‐shop period does not affect deal premium and competition. Also, deals are less likely to be completed when a go‐shop provision is included and when the go‐shop length is longer. However, go‐shops have no effect on the completion of high premium deals. We also find that the presence of a go‐shop provision leads to a positive market reaction to deal announcements. Overall, our findings support the proposition that go‐shops reflect the efforts of target managers to fulfill the Revlon duties in the form of a post‐signing market check, which is consistent with stewardship theory. 相似文献

This paper assesses the distributional consequences of technical changes that improve the efficiency of land and of other inputs in a multifactor crop‐production system. We introduced an equilibrium displacement model (EDM) by using the specification of a factor‐augmenting approach. Given the uncertainty about the EDM parameters, a Monte Carlo simulation is used to produce a distribution of possible return measures. We found that land suppliers (likely farmers) receive a larger share (73%) of total benefits from the adoption of land‐technical change than they do from the adoption of other input technologies. Each input supplier receives a larger share of total benefits from technical change in her own input. However, this result is sensitive to the value of the parameters, especially the value of the elasticity of substitution. We applied the EDM to the case of no‐tillage (NT) to provide insight into how the aggregate return from the adoption of NT was distributed among different groups on the Canadian Prairies. The results of this study can be used by policymakers and funding agencies in order to influence landowners and farming communities to adopt environmentally sound land technologies to achieve both greater agricultural productivity and sustainability. 相似文献
