Using new estimates of ad valorem equivalent of nontariff measures (NTMs) over time, this paper examines NTMs and tariffs’ relationship for a sample of 70 economies for 4,949 products at the 6‐digit harmonized system level over the period 2003–2015. A panel data methodology models the lagged adjustment of NTMs to tariffs, consistent with a causal relationship. Trade policy substitution is found when the models are estimated in both levels and changes; with this holding for both OECD and non‐OECD countries, but not for the agriculture sector in OECD countries. Overall, there is a fairly complete substitution between policy instruments in absolute terms. 相似文献

In this paper, we propose a goal-based investment model that is suitable for personalized wealth management. The model only requires a few intuitive inputs such as size of wealth, investment amount, and consumption goals from individual investors. In particular, a priority level can be assigned to each consumption goal and the model provides a holistic solution based on a sequential approach starting with the highest priority. This allows strict prioritization by maximizing the probability of achieving higher priority goals that are not affected by goals with lower priorities. Furthermore, the proposed model is formulated as a linear program that efficiently finds the optimal financial plan. With its simplicity, flexibility, and computational efficiency, the proposed goal-based investment model provides a new framework for automated investment management services. 相似文献

基于信任理论,从不同角色视角探究各信任要素对分享经济行为意图的影响。通过构建分享经济信任机制概念模型以及实证检验发现:从需求方视角来看,对个体(供给方)3个维度(能力、正直和善意)的信任、对平台善意的信任以及对产品能力的信任对需求意图产生积极地影响。从供给方视角来看,对个体(需求方)能力的信任和对平台3个维度(能力、正直和善意)的信任对供给意图有正向的影响。需求方更关注人与人之间的信任,而供给方则更看重对平台的信任。通过进一步比较还发现,需求方对平台和个体(供给方)的信任聚焦于善意信任,但供给方则是侧重于对平台和个体(需求方)能力的信任。 相似文献

The extant literature shows that institutional investors engage in corporate governance to enhance a firm's long‐term value. Measuring firm performance using the F‐Score, we examine the persistent monitoring role of institutional investors and identify the financial aspects of a firm that institutional monitoring improves. We find strong evidence that long‐term institutions with large shareholdings consistently improve a firm's F‐Score and that such activity occurs primarily through the enhancement of the firm's operating efficiency. Other institutions reduce a firm's F‐Score. Moreover, we find evidence that, while monitoring institutions improve a firm's financial health, transient (followed by non‐transient) institutions trade on this information. 相似文献

Leisure has become a topic of interest in stress-coping research. This study examined the relationships between receiving leisure social support, providing leisure social support, leisure self-determination and leisure competence in older adults and their stress. A total of 639 community-dwelling older adults were recruited. Data were collected using face-to-face surveys, which included measures of leisure social support (receiving and providing), leisure self-determination, leisure competence and stress. Data were analysed using regression analysis. The results indicated that receiving leisure social support, providing leisure social support, leisure self-determination and leisure competence were significantly and negatively correlated with stress and that providing leisure social support was more significantly correlated with reduced stress than the other leisure factors. Implications of the results are discussed. 相似文献

This study adopts a new approach, the multi-choice goal programming (MCGP), to evaluate houses in order to help homebuyers
to find better house based on the residential preferences. According to the function of MCGP, homebuyers can set multiple
housing goals with multiple aspiration levels. This increases the flexibility to find a suitable house. Compared with other
classical methods such as checklist and analytic hierarchy process, MCGP is more efficient, especially while considering a
lot of housing criteria and house alternatives. In order to demonstrate the usefulness of MCGP decision aid for housing selection,
a real case study is then provided. Furthermore, ten volunteers are invited to participate in the empirical experiment. The
results also validate the effectiveness and efficiency of MCGP decision aid. 相似文献

This paper investigates the problem of asymmetric information in Taiwan’s cancer insurance market. Through the survey data, we find evidence of adverse selection existing in this market. Furthermore, we collect additional information on the individual, and find that the individual’s family cancer history contains additional valuable information. It can not only more accurately predict the probability of contracting cancer, as well as predict the willingness to purchase extended cancer insurance, but it can also help to mitigate the severity of adverse selection in the insurance market. 相似文献

An intergenerational (IG) appeal in an advertising campaign usually presents a nostalgic image with family portraits, emphasizing the traditions that have been passed on from generation to generation or harkening back to the ‘good old days’ between father and son, or mother and daughter. The IG appeal can effectively enhance a brand's image and induce that all-important consumer purchase. This paper takes gender differences (father/son or mother/daughter) into consideration while examining two moderators related to branding: (in)congruent brand–gender extension and brand history. Results indicate that a well-established brand history enhances the effects of the IG appeal. In addition, a congruent brand–gender extension increases the effects of the IG appeal. More interestingly, IG appeals can be effective in presenting a less established brand which has an incongruent brand–gender extension. 相似文献
