This paper discusses an optimal investment, consumption, and life insurance purchase problem for a wage earner in a complete market with Brownian information. Specifically, we assume that the parameters governing the market model and the wage earner, including the interest rate, appreciation rate, volatility, force of mortality, premium-insurance ratio, income and discount rate, are all random processes adapted to the Brownian motion filtration. Our modeling framework is very general, which allows these random parameters to be unbounded, non-Markovian functionals of the underlying Brownian motion. Suppose that the wage earner’s preference is described by a power utility. The wage earner’s problem is then to choose an optimal investment-consumption-insurance strategy so as to maximize the expected, discounted utilities from intertemporal consumption, legacy and terminal wealth over an uncertain lifetime horizon. We use a novel approach, which combines the Hamilton–Jacobi–Bellman equation and backward stochastic differential equation (BSDE) to solve this problem. In general, we give explicit expressions for the optimal investment-consumption-insurance strategy and the value function in terms of the solutions to two BSDEs. To illustrate our results, we provide closed-form solutions to the problem with stochastic income, stochastic mortality, and stochastic appreciation rate, respectively. 相似文献
Using a sample of workers and managers employed by a hotel located in Southeastern People’s Republic of China, we investigated the relationship between various human resource management practices and the perceived organizational support (POS) experienced by the employees. We then investigated the effects of POS on employee satisfaction. Our data suggest that hiring practices, training, and compensation practices predict POS. These results are consistent with previous research. We also found that POS influences worker satisfaction and acts as a mediator between select HR practices and satisfaction. This study contributes to the literature by replicating Western-based findings with a Chinese sample and illustrating that the attitudes of Chinese employees can be influenced through the use of HR practices. 相似文献
State-owned (SO) multinational enterprises (MNEs) from emerging economies face two contradictory effects on their foreign operations due to their linkage with their home-country governments. Although home governments provide SO MNEs with resources, the affiliation also exposes SO MNEs to the legitimacy challenges in the host countries. Given this theoretical debate, we propose that home government support may facilitate SO MNEs’ post-entry operations in the host markets. Furthermore, because the legitimacy pressures directed at SO MNEs may be contingent on the interstate relations between the host and home governments facilitated by China’s Belt and Road Initiative (BRI), the BRI cooperative relations may shift the effect of home government support. Using survey and archival data, we find that home government support has a positive impact on the foreign performance of SO subsidiaries. This effect is weaker in countries that are cooperating with the BRI than in those that are not. Moreover, institutional distance weakens the negative interactive effect between BRI cooperation and home government support on the performance of SO MNEs’ foreign subsidiaries. These findings extend the institutional perspective by highlighting an alternative source of legitimacy for MNEs with distinctive attributes and in various host conditions.
