Abstract

The qualitative behavior of the optimal premium strategy is determined for an insurer in a finite and an infinite market using a deterministic general insurance model. The optimization problem leads to a system of forward-backward differential equations obtained from Pontryagin’s Maximum Principle. The focus of the modelling is on how this optimization problem can be simplified by the choice of demand function and the insurer’s objective. Phase diagrams are used to characterize the optimal control. When the demand is linear in the relative premium, the structure of the phase diagram can be determined analytically. Two types of premium strategy are identified for an insurer in an infinite market, and which is optimal depends on the existence of equilibrium points in the phase diagram. In a finite market there are four more types of premium strategy, and optimality depends on the initial exposure of the insurer and the position of a saddle point in the phase diagram. The effect of a nonlinear demand function is examined by perturbing the linear price function. An analytical optimal premium strategy is also found using inverse methods when the price function is nonlinear.  相似文献

Cooperative Research and Development Agreements (CRADAs) between Federal R&D laboratories and private companies in the US are intended, in large part, to transfer technologies developed at Federal R&D laboratories to private companies. We surveyed the Federal laboratory and private CRADA partners involved in CRADAs at Los Alamos National Laboratory in New Mexico in order to identify certain difficulties inherent in CRADAs as mechanisms for technology transfer. Company partners do not share a common organizational culture with their Federal laboratory counterparts, and are critical of the length of time and complexity of government administrative arrangements necessary to form a CRADA.  相似文献

We reassess Mankiw, Romer and Weil's [mrw] version of the Solow model using, as did mrw, cross-sectional data to estimate the steady-state equation governing income per capita levels. The model fails in two critical areas. First, plausible factor shares obtained by mrw are not robust to the substitution of two measures of human capital that are more precise than the secondary school enrollment rates used by mrw. Second, the null hypothesis of an exogenous and identical level of technology in all countries is rejected. We also explain why the Solow model performed well despite the above shortcomings.  相似文献

We consider the estimation of the conditional mode function when the covariates take values in some abstract function space. The main goal of this paper was to establish the almost complete convergence and the asymptotic normality of the kernel estimator of the conditional mode when the process is assumed to be strongly mixing and under the concentration property over the functional regressors. Some applications are given. This approach can be applied in time‐series analysis to the prediction and confidence band building. We illustrate our methodology by using El Nio data.  相似文献

  • Although corporate support for many nonprofit organisations (NPOs) represents only a relatively small component of their overall income its importance is growing. As a consequence, the need to understand corporate giving behaviour in a way that supports the development of strategically targeted and successful marketing campaigns is of growing importance to marketing managers in many NPOs around the globe.
  • This paper presents the findings of a study into the ‘why’ and ‘how’ of corporate giving behaviour in Australia. In the seven case studies examined, there was no strong evidence that Australian corporations give for other than strategic profit maximisation or political reasons. In contrast to the literature, altruistic and managerial utility did not emerge as strong motivational factors.
  • This study also found that corporations are likely to have a number of corporate giving programmes each with its own underlying motivation and strategic purpose which network together to form a hierarchy of corporate giving programmes.
  • The paper concludes by discussing the implications of this research for NPO managers attempting to increase their level of corporate support.

The paper analyzes the phenomenon of industry-specific direct foreign investment (DFI) which occurs with the view to defusing the threat of future protection by the host country (quid pro quo), under alternative imperfectly competitive market structures. It is established that, even in the absence of government intervention, firms in imperfectly competitive markets change the level of trade and DFI in response to future protectionist threats.  相似文献

We formally analyze the pattern and volume of trade by embedding quasilinear preferences in the standard perfectly competitive, two‐factor, two‐good, two‐country trade model. Quasilinear preferences deliver a natural partition of the two goods into a luxury and a necessity, and preserve the validity of the Heckscher–Ohlin and Heckscher–Ohlin–Vanek theorems. In addition, the predicted factor content of trade under quasilinear preferences is smaller (larger) than the predicted factor content of trade under homothetic preferences if and only if the luxury good is capital (labor) intensive. This result offers a novel explanation for the “missing‐trade” mystery.  相似文献

The accounting profession has emphasized the need for ethics education in the accounting curriculum. The current study examines professional commitment and anticipatory socialization, operationalized by perception of financial reporting, as possible determinants of Accounting students’ ethical perceptions and intentions. Accounting students with higher levels of professional commitment and higher perception of the importance of financial reporting were more likely to perceive questionable actions as unethical and less likely to engage in such actions compared to those students with lower commitment and lower perception of financial reporting. The results have implications for accounting instructors and accounting employers as they socialize students in the accounting profession at this early stage.  相似文献
