We consider a pure exchange economy consisting of a single risky asset whose dividend drift rate is modeled as an Omstein-Uhlenbeck process, and a representative agent with power-utility who, in equilibrium, consumes the dividend paid by the risky asset. Endogenously determined interest rates are found to be of the Vasicek (1977) type the mean and variance of the equilibrium stock price are stochastic and have mean-reverting components A closed-form solution for a standard call option is determined for the case of log-utility. Equilibrium values have interesting implications for the equity premium puzzle observed by Mehra and Prescott (1985) 相似文献

The question of whether optimal provision of these services comes mainly from established relationships between banks and client firms or can result from arms'‐length market transactions has been the topic of considerable recent debate. This discussion has paralleled the debate in the commercial banking literature on the “specialness” of banks and whether lending can and should be relational or purely transactional. Whether the provision of investment bank services is relationship‐based or transactional is especially relevant now thanks to recent trends that have blurred the distinction between commercial and investment banks, and changed the competitive landscape for investment bank services. In their study summarized in this article, the authors examine whether investment bank‐client relationships create valuable relationship‐specific capital using stock market evidence from the period surrounding the collapse of Lehman Brothers. Specifically, they studied the effect of the Lehman collapse on companies that used Lehman for (1) underwriting equity offerings, (2) underwriting debt offerings, (3) advice on mergers and acquisitions, (4) analyst research services, and (5) market‐making services. The study addressed two specific questions. First, which investment bank services, if any, are associated with the creation of relationship‐specific capital; and second, what are the value drivers of this relationship capital? The authors report finding that companies that used Lehman as lead underwriter for public equity offerings experienced significantly negative abnormal stock returns in the days surrounding Lehman's bankruptcy announcement. By contrast, they find no significant reaction to the announcement for Lehman's debt underwriting clients or any of the other client categories they examine. While most of these investment bank services have at least the potential to create relationship‐specific capital, the authors' findings suggest that except for equity underwriting, all the other investment bank services appear to be transactional rather than relationship‐based, at least in the average case. Moreover, the authors report significant differences even among different groups of Lehman's equity underwriting clients. An equity underwriting relationship with Lehman appears to have been especially valuable for smaller, younger, and more financially constrained firms—those firms which presumably had a high degree of dependence on Lehman to access the capital market. 相似文献

We study the mutual relationships between institutional ownership, analyst following and share prices. We show that the pressure on firms to set lower share prices to attract analysts is attenuated by institutional monitoring. Our theory refutes the assumed causal relation between share price and institutional ownership, attributed to the share price–liquidity relation, and we show empirically that share prices and institutional ownership are positively related after controlling for liquidity. Our study provides a rationale for why better firms generally maintain higher share price levels, and offers new insights into the puzzling empirical linkages observed between nominal share price levels and firm fundamentals. 相似文献

The authors use a capital budgeting example to show students how to incorporate price elasticity into financial analysis as an application of what students learn in their microeconomics course. They present simple as well as more advanced price-quantity relationships, and using various “what-if” scenarios; the authors show how risk analysis can be used to improve revenue projections and valuation models. A project analysis example is employed to illustrate results for negative predictive value and IRR based on three models of price elasticities across a range of potential product pricing. Students are then encouraged to replicate and create similar models, helping them improve their vital Excel and financial modeling skills. 相似文献

In the first phase of pharmaceutical development, and assuming that the probability of positive response increases with dose, the main statistical goal is to estimate a percentile of the dose–response function for a given target value . We compare the Maximum Likelihood and centred isotonic regression estimators of the target dose and we discuss several performance criteria to assess inferential precision, the amount of toxicity exposure and the trade-off between them for a set of some exemplary adaptive designs. We compare these designs using graphical tools. Several scenarios are considered using simulation, including the use of several start-up rules, the change of slope of the dose-toxicity function at the target dose and also different theoretical models, as logistic, normal or skew-normal distribution functions. 相似文献

This article describes the process for preparing a survey, which will be used to measure relevant variables, which are involved
in a study of training needs in a Spanish sports organisation. The variables which have been considered are: problems and
difficulties in carrying work of specific positions; “strong points” in carrying out this work; usefulness of the training
received in facing and solving the above-mentioned problems and difficulties; usefulness of the training received in acquiring
and strengthening these “strong points” in carrying out work; opinion and suggestions with respect to future training. Due
to the applied nature of the study, a data collection methodology was designed which was based on interviews and group discussions
with a representative sample of workers. Finally, the predictive capacity of perception, which workers have, of their motivation
at work was clearly shown in order to then identify different attitude and conduct patterns. 相似文献

This article discusses how the slowdown in the real estate market during the most recent economic and financial crisis has affected residential tourism destinations on the Spanish coast. The afore-mentioned crisis, which gave rise to a standstill in residential activity, coincided with the turbulences experienced in the competing destinations of Northern Africa, which brought about a record number of international tourist arrivals to Spain. The resulting situation enables us to explore the future scenario of all the Spanish destinations that, due to the depletion of available land, are reaching their maximum levels of urban growth. Examining the case of Calpe, a destination which is representative of the Spanish Mediterranean, the study analyses whether the foreseeable dynamics for the future are conceptualized in the favourable terms that characterize “sustainable development” or, on the contrary, exhibit negative implications which the classic economists refer to as the “steady state”. 相似文献

Intrapreneurial activity is positively associated with the organizational growth, and the factors that stimulate such behaviors need to be identified. The general goal of this work is to explore the relationship of authentic leadership with employees’ intrapreneurial behavior and the intervening processes. A correlational study was carried out with 212 employees of Spanish companies, in which two cross-level mediation hypotheses were tested. The results obtained indicate that employees’ organizational identification and organizational empowerment both mediate the relationship between authentic leadership and employees’ intrapreneurial behaviors. In this work, we note the importance of including authentic leadership as an antecedent of intrapreneurship. 相似文献

The empirical analyses of firm diversification decisions, both for new activities (new products) and markets (for example, new routes for airlines), have usually estimated a binary dependent variable model for each of the decisions the firm makes. To obtain consistent estimators, every relevant effect must be considered in the specification. As this will hardly happen, the presence of nonobserved firm effects (either because such data do not exist or because it is impossible to obtain them) must be econometrically treated, because it causes inconsistency in the estimations. In this paper we propose to use the estimators provided by the maximization of the conditional likelihood function in problems of this kind because they give consistent results even when unobserved firm effects are present. Finally, we apply this technique to an example of diversification among Spanish manufacturers. © 1997 John Wiley & Sons, Ltd. 相似文献

The football club market is changing fast in the social media era. In this global market, clubs must maintain or improve fans’ attendance at the stadium; simultaneously, they need, more than ever, to take care of social media. The aim of this article is to test and discuss a comprehensive approach to analysing the performance of football clubs regarding their multiplicity of objectives. We analyse the efficiency of English Premier League (EPL) clubs during three seasons (2012/13–2014/15). The methodologies employed are data envelopment analysis (DEA) and a bootstrapped DEA model. The input is the market value of the squad, and the outputs are sports results, total revenue, the ratio of stadium utilization during the season and an index of social media impact. The results are robust to alternative estimation methods and indicate that EPL clubs still have a margin for improving their overall efficiency, mainly the medium clubs. The analysis of football clubs’ performance with the proposed comprehensive approach provides a useful tool to help managers with evaluation and feedback considering the actual context of the market. The approach brings closer the opportunity to design appropriate strategies to improve clubs’ efficiency as well as competition policies. 相似文献
