Personalized goal-based investing via multi-stage stochastic goal programming

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.

Vertical Specialization and Trade Growth in Northeast Asia

As the global economy has become further integrated, the international production chain has become more sophisticated, with diversified stages of production located in different countries. Economic theorists have argued that the fragmentation of the global production chain is partly attributable to the high growth in international trade over the past several decades. In this study, we examine vertical specialization in China, Japan and Korea, and its contribution to these nations' trade. Using a multilevel model, it is illustrated that vertical specialization has encouraged increases in trade among all three countries. In particular, China's outcome is remarkable considering how recently it became a member of the WTO.     

Prepayment and future cross-buying: an exploratory analysis

Recent research has provided important insights on consumers’ preferences for prepayment mechanisms and on its impact on consumption of a given product or service. However, little is known about how prepayment influences future purchases of goods and services. We consider this question in a contractual setting within the services industry, involving different purchasing decisions over time. Based on a large-scale empirical test, we find that prepay customers make fewer changes to their cross-buying levels (i.e., the number of different services they buy from the company) from one contractual period to another, and that this effect is more salient for the firm's new customers. We propose possible explanatory mechanisms for this effect. For instance, based on mental budgeting theory, we suggest that prepayment customers may set mental budgets and track expenditures against this budget leading them to resist further investments. Alternatively, prepayment customers may be more certain about their consumption behavior leading to fewer changes over time.

     

基本公共服务均等化如何促进了个人创业--来自医保改革的证据

在高质量发展目标下,推行基本公共服务均等化、促进大众创业是中国经济新常态下的工作重点。基于中国城镇职工基本医疗保险在创业者和非创业者之间可得性的外生差异,本文使用中国健康与营养调查(CHNS)的微观数据,研究社会保险这一基本公共服务在创业者和非创业者之间的相对可得性如何影响个人的创业决策。我们发现,如果城镇职工基本医疗保险对于非创业者更可得,将成为“创业枷锁”,降低个人选择创业的可能性;如果城镇职工基本医疗保险对于创业者更可得,将成为“创业催化剂”,提高个人选择创业的可能性。此外,我们发现,城镇职工基本医疗保险的“创业催化剂”作用对于来自中等收入家庭和小家庭的个人更为显著,而“创业枷锁”效应则更多地影响城镇职工基本医疗保险在薪酬体系中重要性更高的个体。本文认为中国的社会保险对于大众创业具有积极正面的影响。这对于我国社会保险制度的设计和促进经济高质量发展具有重要意义。     

Doing business in Poland: What U.S. managers need to know

Poland has been and continues to be the leader of the transition economies of Eastern Europe. This study provides an in‐depth look at the ongoing economic, legal, and administrative policies of the Polish government in laying the ground‐work for a free‐market society. With the smaller business in mind, we first examine how the government of Poland moved decisively to lay the cornerstone for a private‐sector economy. Next, we demonstrate how Poland redirected its political and legal processes for long‐term global business. Finally, we describe what the U.S. government is doing to help Poland become a better trading partner and what this means to interested American firms. While there are many deep‐seated positive changes throughout Poland as it becomes a more significant global business player, there also are many challenges that must be understood by interested U.S. businesses if their investments in Poland are to be successful. © 2004 Wiley Periodicals, Inc.     

Motivations and Use Context in Mobile Tourism Shopping: Applying Contingency and Task–Technology Fit Theories

Mobile tourism shopping is an emerging market, but there is little theoretically based research on the topic. This study investigates the impact of motivations (value, enjoyment, time saving and mobility) on consumer satisfaction by applying contingency and task–technology fit theories in the mobile tourism shopping context. The results show that value and enjoyment have significant effects on satisfaction. Use context is found to have a full mediating role between time saving and satisfaction as well as between mobility and satisfaction. This study offers theoretical and practical contributions to the tourism literature and mobile tourism industry. Copyright © 2013 John Wiley & Sons, Ltd.     

商业年金消费决策的行为经济学分析

商业年金是我国养老保险体系的重要组成部分,虽然近年来我国在政策层面不断推动商业年金的发展,但是我国居民的商业年金需求仍然十分低,存在“年金谜题”现象。本文从行为经济学的视角展开对商业年金消费决策的分析,首先从理论层面阐述了行为因素对商业年金消费决策的影响机制,随后设计调查问卷收集个体数据,从实证层面进行了验证。结果发现,主观概率、心理账户、信息感知、金融素养等行为因素会显著影响个人的商业年金消费水平,其他客观因素如性别、年龄、婚姻状况、风险态度以及收入水平等也会显著影响个人的商业年金消费水平。基于本文研究结果,认为未来商业年金回归保障属性、弱化个人账户概念以及发展保险咨询服务等可以带来商业年金需求的提升。     

Customers’ Risk Factor Disclosures and Suppliers’ Investment Efficiency

This study examines the effect of downstream firms’ (i.e., customers’) risk factor disclosures contained in annual reports on the investment efficiency of upstream firms (i.e., suppliers). We find that more informative disclosures of customers’ risk factors are associated with less under‐ or overinvestment by suppliers. In addition, this inverse association is stronger when the suppliers are at a bargaining disadvantage, when they operate in the durable goods industries, and when they are more concerned about the volatility of future demand. Overall, our results suggest that risk factor disclosures provided by firms in their annual reports contain useful information that could potentially help their suppliers achieve better investment efficiency.
