The increasing unacceptability of the concept of entity law and the emergence of the doctrine of enterprise law with respect to many aspects of the legal relationships of parent and subsidiary corporations particularly in insolvent situations is a very interesting issue. This change is very significant because it reflects a growing unwillingness on the part of the courts and legislatures to continue accepting the traditional view of corporate law when it no longer corresponds to the economic reality of the modern business enterprise in a complex industrialized international society. This paper examines the American case law and in particular the decisions that have imposed liability where a company is liable for the obligations of an insolvent subsidiary and by contrast the decisions that have denied liability. The paper also examines the position in Argentina within the Argentine law and the UNCITRAL recommendations in respect of liability issues within corporate groups in insolvency.

Technological resources in the form of patents, trade secrets, and know‐how have become key assets for modern enterprises. This paper addresses a critical issue in technology and innovation management, namely, the commercial exploitation of technological resources resulting from research and development (R&D) investments. Extracting economic value from these resources by maximizing the benefits for shareholders is an extremely challenging task because technological resources are intangible, idiosyncratic, uncertain, predominantly tacit, and with poorly defined property rights. In their attempt to extract the maximum value from their technological resources, firms increasingly combine their internal exploitation through new product development (NPD) with external exploitation through licensing. However, most existing studies on NPD and technology licensing have treated the two exploitation paths independently and in isolation, which has resulted in two separate research streams using different theories and addressing different managerial challenges. The purpose of this paper is to contribute to filling this gap by developing and testing a comprehensive conceptual framework that simultaneously considers the antecedents affecting the successful implementation of NPD and licensing strategies as well as their consequences on firm profitability. The paper in particular investigates the effects of the interplay between technological resources and three types of complementary resources, marketing, manufacturing, and relational. We test the model using structural equation modeling on a sample of 733 Spanish manufacturing firms observed from 2003 to 2007. The data provide support for the existence of different paths to market firm technologies: an internal path, whereby the ownership of technological resources fully explains NPD performance, and an external path, whereby high intensity of marketing and relational resources reinforces the positive effect of technological resources on licensing performance. This sustains the relevance of the resource‐based value‐enhancing effects of complementary resources in licensing, as opposed to the motivation‐reducing effects advanced by transaction cost‐based literature. Moreover, the empirical analysis shows a substitution effect between NPD and licensing, whereby their simultaneous pursuit at intense levels is associated with lower profit margins. This provides evidence of the much theorized, but seldom tested, rent dissipation effect. These findings offer several contributions to research on licensing, NPD, open innovation, and the resource‐based view of the firm. On a managerial level, they suggest that achieving maximum value from proprietary technologies may not entail exploiting them both through external and internal paths. Managers are also informed that the resource combinations that enhance licensing performance include marketing and relational resources. 相似文献

We analyze the statistical properties of three price discovery measures: The variance ratio, the weighted price contribution (WPC), and the R2 of unbiasedness regressions. We find that, if the price process is a driftless martingale, only the WPC is an unbiased estimator for the return variance explained during a time interval. For autocorrelated processes with a drift, only the R2 of the unbiasedness regression is consistent, but it is biased for small samples. 相似文献

The paper estimates the relationship between the nominal Treasuries rate and inflation in China. The dynamic econometric analysis yields a preferred, automatically reduced, empirical model revealing a Fisher effect. But the results are sensitive to using different sub-samples encompassed in the decade-and-a-half period following the disassociation of Treasuries from the People’s Bank of China administered interest rates at the end of the 1990s. 相似文献

The implied volatility skew has received relatively little attention in the literature on short-term asymptotics for financial models with jumps, despite its importance in model selection and calibration. We rectify this by providing high order asymptotic expansions for the at-the-money implied volatility skew, under a rich class of stochastic volatility models with independent stable-like jumps of infinite variation. The case of a pure-jump stable-like Lévy model is also considered under the minimal possible conditions for the resulting expansion to be well defined. Unlike recent results for “near-the-money” option prices and implied volatility, the results herein aid in understanding how the implied volatility smile near expiry is affected by important features of the continuous component, such as the leverage and vol-of-vol parameters. As intermediary results, we obtain high order expansions for at-the-money digital call option prices, which furthermore allow us to infer analogous results for the delta of at-the-money options. Simulation results indicate that our asymptotic expansions give good fits for options with maturities up to one month, underpinning their relevance in practical applications, and an analysis of the implied volatility skew in recent S&P 500 options data shows it to be consistent with the infinite variation jump component of our models. 相似文献

This article studies the performance of the high-order moment capital asset pricing model (CAPM) market models in emerging markets. We apply the cubic market model (4-moment CAPM) to 16 emerging market stock indices ranging from January 2010 to September 2015. Performance of the model is evaluated through the Fama and MacBeth’s two-step regression and through different corrections proposed in the literature, as well as generalized method of moments (GMM) estimation. According to Fama–MacBeth’s procedure, CAPM, the quadratic and cubic market models seem to be insignificant for the analyzed sample; however, the GMM estimation shows that quadratic model is valid for Indian, Polish, and Thai country indices, whereas cubic market model is accurate for Indian country index. 相似文献

The paper tests the hypothesis that female applicants have a lower probability of being hired from a pool of applicants than their male counterparts. The results indicate that male and female candidates have about the same probability of being hired independently of the type of vacancy. The probability of hiring a candidate of a certain sex is therefore determined by the gender composition of the pool of applicants who have selected themselves on the basis of job characteristics, hiring standards and the type of sector. This indicates that male and female job-seekers select themselves in such a way that they have equal probabilities of being accepted. 相似文献
