Evaluation of the mathematical and economic basis for conversion processes in the LEAP energy-economy model

An evaluation was made of the mathematical and economic basis for conversion processes in the LEAP energy-economy model. Conversion processes are the main modelling subunit in LEAP used to represent energy conversion industries and are supposedly based on the classical economic theory of the firm. The study arose out of questions about the uniqueness and existence of LEAP solutions and their relation to classical equilibrium economic theory. An analysis of classical theory and LEAP model equations was made to determine their exact relationship. The conclusions drawn from this analysis were that LEAP theory is not consistent with the classical theory of the firm. Specifically, the capacity for factor formalism used by LEAP does not support a classical interpretation in terms of a technological production function for energy conversion processes. The economic implications of this inconsistency are suboptimal process operation and short term negative profits in years where plant operation should be terminated. A new capacity factor formalism, which retains the behavioural features of the original model, is proposed to resolve these discrepancies.     

对外贸易与宁波经济发展的关系

亚洲金融危机之后，宁波乃至全国的外贸都面临严峻的考验，在这种条件下，中国政府提出扩大内需的措施来缓解不利的经济发展环境。宁波的对外贸易乘数逐渐减少，出口对经济的牵动作用下降。良性发展的经济不是仅仅依靠国内市场或国际市场，而是应充分利用国际、国内两个市场、两种资源，通过两个市场的发展，共同促进宁波经济的发展。本文拟通过对宁波对外贸易发展现状的实证分析，指出宁波应重视国内市场，真正实现国内市场与国外市场的互动，实现国内需求与国外需求的同时增长，带动整个宁波经济的发展。     

浙江省油桐生产动态的分析

浙江省栽培油桐的历史悠久 , 在抗日战争以前的本世纪二三十年代 ,国际市场桐油价格十分昂 贵 ,浙江省由于紧靠上海 ,出口便利 ,油桐种植相当发达 ,桐油的年产量曾高达 1 . 5× 10 7 kg,约相当于近 10年来我国年平均出口量的 70% ;抗日战争期间 ,桐油的销路受阻 ,浙江省的种桐业逐渐衰落 ;抗战胜 利后 ,由于国际市场购买力不旺 ,种桐业再也没有恢复往日的辉煌. 从 50年代初到现在 ,浙江省的油桐 连年减产 ,并有继续一路下滑的趋势 ,其原因一方面是由于国内外市场对桐油的需求有限 ,另一方面则 是由于农村产业结构的调整导致了浙江等沿海省份的桐农向其它收益更高的行业转移 .     

Rational instability in the natural coalition forming

The work aims to investigate a paradigm of instability in coalition forming among countries, using a model inspired from Statistical Physics. The instability is a consequence of decentralized maximization of the individual benefits where contradictory associations into coalitions occur due to independent evolution of pairwise propensity bonds. In contrast to the existing literature we analyze the phenomena within a long horizon rationality of actors. This allows to explore the complex behaviors and phenomena such as instability, infinite cycling and non-optimal stability. Along with the formal implementation, we illustrate the phenomena in a multi-thread simulation created for this aim, and provide analysis of several real cases including the Eurozone.     

Electrocatalytic one pot synthesis of medicinally relevant 4H-benzo[g]chromene and pyrano[2,3-g]chromene scaffold via multicomponent-domino approach

A highly efficient one pot, multicomponent synthesis of 4H-benzo[g]chromene and pyrano[2,3-g]chromene derivatives are reported by electrochemically stimulated condensation of an aromatic aldehyde, malononitrile and some enolizable acidic compounds in ethanol at room temperature under constant current density. By utilizing common electrode materials and a simple constant current protocol, this method is a new alternative to conventional methods.
