Trade networks and economic fluctuations in Asian countries

The paper presents a new methodology, based on tensor decomposition, to map dynamic trade networks and to assess its strength in forecasting economic fluctuations at different periods of time in Asia. Using the monthly merchandise import and export data across 33 Asian economies, together with the US, EU and UK, we detect the community structure of the evolving network and we identify clusters and central nodes inside each of them. Our findings show that data are well represented by two communities, in which People's Republic of China and Japan play the major role. We then analyze the synchronisation between GDP growth and trade. Furthermore we apply our model to the prediction of economic fluctuations. Our findings show that the model leads to an increase in predictive accuracy, as higher order interactions between countries are taken into account.

Biological Adaptation in Human Societies: a ‘Basic Needs’ Approach

The groundzero premise (so to speak) of the biological sciences is that survival and reproduction is the basic, continuing, inescapable problem for all living organisms; life is at bottom a survival enterprise. It follows that survival is the paradigmatic problem for human societies as well; it is a prerequisite for any other, more exalted objectives. Although the term adaptation is also familiar to social scientists, until recently it has been used only selectively, and often very imprecisely. Here a more rigorous and systematic approach to the concept of adaptation is proposed in terms of basic needs. The concept of basic human needs has a venerable history – tracing back at least to Plato and Aristotle. Yet the development of a formal theory of basic needs has lagged far behind. The reason is that the concept of objective, measurable needs is inconsistent with the theoretical assumptions that have dominated economic and social theory for most of this century, namely, valuerelativism and cultural determinism. Nevertheless, there have been a number of efforts over the past 30 years to develop more universalistic criteria for basic needs, both for use in monitoring social wellbeing (social indicators) and for public policy formulation. Here I will advance a strictly biological approach to perationalizing the concept of basic needs. It is argued that much of our economic and social life (and the motivations behind our revealed preferences and subjective utility assessments), not to mention the actions of modern governments, are either directly or indirectly related to the meeting of our basic survival needs. Furthermore, these needs can be specified to a first approximation and supported empirically to varying degrees, with the obvious caveat that there are major individual and contextual variations in their application. Equally important, complex human societies generate an array of instrumental needs which, as the term implies, serve as intermediaries between our primary needs and the specific economic, cultural and political contexts within which these needs must be satisfied. An explicit framework of Survival Indicators, including a profile of Personal Fitness and an aggregate index of Population Fitness, is briefly elucidated. Finally, it is suggested that a basic needs paradigm could provide an analytical tool (a biologic) for examining more closely the relationship between our social, economic and political behaviors and institutions and their survival consequences, as well as providing a predictive tool of some value.     

对我国现时夫妻财产制度的探讨

夫妻财产制度，是有关夫妻财产的使用、归属、管理、收益，以及夫妻债务的清偿，夫妻家庭生活等费用的负担，婚姻终止时夫妻财产的清算和分割等的法律制度。夫妻财产制度是夫妻婚姻家庭生活得以正常运转的物质保证，因而它的完善关系到夫妻财产关系平等与否，关系到与夫妻发生交易的第三人的利益安全问题，关系到社会经济的发展问题。     

美国《社区再投资法案》理论争议与实践述评

美国《社区再投资法案》的颁布实施以及修正案的实施,鼓励了商业银行尤其是那些准备或正在进行并购的商业银行对低收入群体和少数民族居户抵押贷款的增长.该法案对于改善中低收入社区融资困难的状况起到了不可小视的作用.但CRA并不能有效解决市场失败和信贷歧视,其成本大于收益,且加重了市场扭曲.因此,CRA在理论界有所争议.我国正在推进信用社区建设,《社区再投资法案》对我国社会信用体系建设具有一定的借鉴作用.     

西方产业竞争政策的体系和目标

本文讨论美国、欧共体和日本的竞争政策的方法和体系的差异问题。美国的竞争政策侧重于追求消费者剩余和生产者剩余最大化 ,强调通过竞争的作用来达到这一经济效率目标。欧共体的竞争政策则强调在消费者福利的基础地位 ,通过协调竞争规则来促进欧共体经济一体化的进程。日本的反垄断法原本从西方吸收过来的 ,经过半个世纪的发展和演变 ,已经具有明显的日本特色 ,其基本功特征是对价格机制的运作缺乏信任 ,对规模经济神话的盲目崇拜和信任 ,结果是经常提倡和鼓励那种必然会导致寡占市场结构的兼并活动。     

Rationality,foolishness, and adaptive intelligence

Technologies of model‐based rationality are the core technologies of strategic management, having largely replaced earlier technologies that placed greater reliance on traditional practice or on communication either with the stars or with the gods. The technologies used by organizations in their pursuit of intelligence can be imagined to change over time as a result of responding to the successes and failures associated with the technologies. Although technologies of rationality seem clearly to be effective instruments of exploitation in relatively simple situations and to derive their adaptive advantage from those capabilities, their ventures in more complex explorations seem often to lead to huge mistakes and thus unlikely to be sustained by adaptive processes. Whether their survival as instruments of exploratory novelty in complex situations is desirable is a difficult question to answer, but it seems likely that any such survival may require hitchhiking on their successes in simpler worlds. Survival may also be served by the heroism of fools and the blindness of true believers. Their imperviousness to feedback is both the despair of adaptive intelligence and, conceivably, its salvation.

The future of India's obsolete dams: Time to review their safety and structural integrity

India has built over 5000 large dams till date to boost electric power and to enhance irrigated agriculture. In spite of this big dam building venture, India lacks expertise in decommissioning old dams. As a matter of fact, India has more than 500 large dams that were built 50 years ago, and 100 of them have passed over a century. This article analyses the existing facts on India's outdated dams, their safety matters and recommends future strategies to safeguard the large dams from potential future threats.
