We consider a sequence of financial markets that converges weakly in a suitable sense and maximize a behavioral preference functional in each market. For expected concave utilities, it is well known that the maximal expected utilities and the corresponding final positions converge to the corresponding quantities in the limit model. We prove similar results for nonconcave utilities and distorted expectations as employed in behavioral finance, and we illustrate by a counterexample that these results require a stronger notion of convergence of the underlying models compared to the concave utility maximization. We use the results to analyze the stability of behavioral portfolio selection problems and to provide numerically tractable methods to solve such problems in complete continuous‐time models.  相似文献

Due to the differences in economic and social conditions among the Belt‐and‐Road (B&R) countries, resources exchange might bring significant effect on companies and organizations in these countries. In recent years, vigorously developing university education and attracting more outstanding international students have become important means for “B&R” countries to expand education market and enhance international influence. However, there is limited research discussing the impact of “B&R” on the internationalization of higher education. Taking the sponsoring country (China) of the “B&R” strategy as an example, this article explores the impact of this strategy on Chinese universities' expansion in the education market, and further analyzes the important relevant factors from the perspectives of international competitiveness. The findings show that the B&R Initiative has a significant impact on the expansion of Chinese universities in overseas markets along the route. Furthermore, we have found “push” factors related to China's macro and micro environments, and “pull” factors associated with countries along the B&R route.  相似文献

BEHAVIORAL PORTFOLIO SELECTION IN CONTINUOUS TIME   总被引:5,自引:0,他引:5  
This paper formulates and studies a general continuous-time behavioral portfolio selection model under Kahneman and Tversky's (cumulative) prospect theory, featuring S-shaped utility (value) functions and probability distortions. Unlike the conventional expected utility maximization model, such a behavioral model could be easily mis-formulated (a.k.a. ill-posed) if its different components do not coordinate well with each other. Certain classes of an ill-posed model are identified. A systematic approach, which is fundamentally different from the ones employed for the utility model, is developed to solve a well-posed model, assuming a complete market and general Itô processes for asset prices. The optimal terminal wealth positions, derived in fairly explicit forms, possess surprisingly simple structure reminiscent of a gambling policy betting on a good state of the world while accepting a fixed, known loss in case of a bad one. An example with a two-piece CRRA utility is presented to illustrate the general results obtained, and is solved completely for all admissible parameters. The effect of the behavioral criterion on the risky allocations is finally discussed.  相似文献

This paper investigates the impact of “One Belt & One Road” as an exogenous policy shock on the utilisation of foreign capital in China in the short term. Based on provincial panel data for the years 2003–15, the empirical study is conducted with difference‐in‐differences design. The first difference is whether a province is an OBOR province, and the second is whether “One Belt & One Road” initiative has been proposed. The empirical results suggest the utilisation of foreign capital in OBOR provinces has decreased significantly compared to non‐OBOR provinces after the initiative has been proposed. The study has further shown that the OBOR construction not only means factor movements and projects but also stands for policy shock. Its impact on utilisation of foreign capital cannot be simply captured by the commonly quantifiable “going global” indicators, namely outward direct investment, overseas contracted projects or overseas labour services. The negative impact of the initiative on foreign capital utilisation is strongly reflected in the OBOR provinces with low levels of economic development, heavy fiscal burdens and high proportions of state‐owned economy. In the short term, the negative impact of the initiative on foreign capital utilisation may be due to its role in resource competition and signal delivering. The former means that the OBOR initiative may induce resource competition between “going global” and “bringing in,” and the latter suggests that this initiative is likely to be regarded as a “signal” by foreign investors that “going global,” not “bringing in,” has become the priority of the government.  相似文献

The collapse in global trade during the 2008–09 crisis has been widely studied using the developed nation(s) data. I use firm‐level data from Indian manufacturers to show that: (a) Indian firms experience strong negative demand shocks concerning their exports to the USA and the EU, the effect being significantly higher in case of the USA. Results assert that 1% increase in the exposure towards the crisis‐affected zones (the USA and the EU combined) reduces an average Indian manufacturing firm's export earnings by 1.17%–1.36%; (b) trade in consumer non‐durables and durables are the two most affected sectors, impact being higher for the latter; (c) evidence in support of similar effects throughout the size distribution of firms, with the effect being highest for small or the most vulnerable firms; (d) drop in demand, as a result of the 2008–09 crisis, only affects the high‐exposure industries. My results are robust to IV analysis and a variety of checks.  相似文献

We fill a gap in the proof of a (rather critical) lemma, Lemma B.1, in Jin and Zhou (2008: Math. Finance 18, 385–426). We also correct a couple of other minor errors in the same paper.  相似文献

A portfolio choice model in continuous time is formulated for both complete and incomplete markets, where the quantile function of the terminal cash flow, instead of the cash flow itself, is taken as the decision variable. This formulation covers a wide body of existing and new models with law‐invariant preference measures, including expected utility maximization, mean–variance, goal reaching, Yaari's dual model, Lopes' SP/A model, behavioral model under prospect theory, as well as those explicitly involving VaR and CVaR in objectives and/or constraints. A solution scheme to this quantile model is proposed, and then demonstrated by solving analytically the goal‐reaching model and Yaari's dual model. A general property derived for the quantile model is that the optimal terminal payment is anticomonotonic with the pricing kernel (or with the minimal pricing kernel in the case of an incomplete market if the investment opportunity set is deterministic). As a consequence, the mutual fund theorem still holds in a market where rational and irrational agents co‐exist.  相似文献

We consider an optimal insurance design problem for an individual whose preferences are dictated by the rank‐dependent expected utility (RDEU) theory with a concave utility function and an inverse‐S shaped probability distortion function. This type of RDEU is known to describe human behavior better than the classical expected utility. By applying the technique of quantile formulation, we solve the problem explicitly. We show that the optimal contract not only insures large losses above a deductible but also insures small losses fully. This is consistent, for instance, with the demand for warranties. Finally, we compare our results, analytically and numerically, both to those in the expected utility framework and to cases in which the distortion function is convex or concave.  相似文献

Many investment models in discrete or continuous‐time settings boil down to maximizing an objective of the quantile function of the decision variable. This quantile optimization problem is known as the quantile formulation of the original investment problem. Under certain monotonicity assumptions, several schemes to solve such quantile optimization problems have been proposed in the literature. In this paper, we propose a change‐of‐variable and relaxation method to solve the quantile optimization problems without using the calculus of variations or making any monotonicity assumptions. The method is demonstrated through a portfolio choice problem under rank‐dependent utility theory (RDUT). We show that this problem is equivalent to a classical Merton's portfolio choice problem under expected utility theory with the same utility function but a different pricing kernel explicitly determined by the given pricing kernel and probability weighting function. With this result, the feasibility, well‐posedness, attainability, and uniqueness issues for the portfolio choice problem under RDUT are solved. It is also shown that solving functional optimization problems may reduce to solving probabilistic optimization problems. The method is applicable to general models with law‐invariant preference measures including portfolio choice models under cumulative prospect theory (CPT) or RDUT, Yaari's dual model, Lopes' SP/A model, and optimal stopping models under CPT or RDUT.  相似文献
