Mortgage Markets and Inter-Regional Differences in Conventional Mortgage Terms

One of the purposes of the secondary mortgage market is to move funds from areas of capital surplus to areas of capital shortage. If mortgage funds move freely throughout the economy then the price of mortgage funds (the terms of the mortgage) should be the same everywhere. Thus, if the secondary mortgage market is efficient, mortgage terms should show less geographic variation after the secondary market began in 1970 than they showed before. In this paper, the efficiency of the market is tested in two stages. In the first, the average terms of mortgage loans in 1968 and 1978 are examined to determine whether they became more homogeneous after the secondary market was begun. In the second stage, the terms are modeled as a function of region, year by region interaction variables, foreclosure rates, the usury ceiling and the average cost of funds. This model is estimated and analyzed using a multivariate multiple regression technique.     

Green Project Bonds als finanzielle Alternative für Energieunternehmen

The reorientations of energy policy, and in particular the promotion of renewables, have changed the market conditions for energy companies significantly. Over recent years, the resulting challenges put the energy companies’ financial ratios under severe stress. As the need to invest remains urgent, energy firms seek to broaden and diversify their sources of funding. Against this backdrop, the article addresses an innovative form of securities-based debt financing for energy companies, which explicitly links the financing transaction to the investing of funds in renewable energy projects. Due to the early stage of development of so called green (project) bonds, an initial disambiguation is essential. Thereafter, current market processes, structures and rules are considered. Based hereupon, it is possible to discuss the new opportunities that green project bonds afford energy companies.     

我国封闭式基金的业绩和驱动因素研究

以基金的平均周收益率、詹森指数、特雷诺指数、夏普指数以及基金的选股能力、择时能力、抗跌能力为基础研究了54只封闭式基金的业绩排名,发现平均周收益率高的基金经过风险调整后的回报率仍然很高,这说明能够在一定程度上控制风险的基金其业绩较佳;大多数平均周收益率高的基金其收益突出是因为其选股能力突出,而这些选股能力突出的基金中大部分的基金抗跌能力也很强;少数平均厨收益率高的基金其收益突出是因为其择时能力突出,但这部分择时能力强的基金却未表现出强的抗跌能力。根据这些指标提出了基金的诊断式评级,以为投资者和监管机构提供更多的信息。

The Year in Review: Economics at the Antitrust Division, 2006–2007

In this paper, we evaluate the scope of Chadwick’s claim on the superiority of competition for the market over competition in the market under incomplete information. We firstly characterize the expected outcome achieved under competition in the market at a Cournot Bayesian-Nash equilibrium. Then we characterize the optimal expected outcome achieved under a competition for the market mechanism designed by a government facing a shadow cost of public funds. We show that a regulated monopoly selected by an auction mechanism results in higher expected welfare than does duopoly competition when the entry cost is low but that the opposite holds when the market size is small and the entry cost is high for some values of the shadow cost of public funds. These results are explained by the influence of adverse selection on the entry decision at the Cournot equilibrium and by the level of expected total fixed costs in both mechanisms.      

认真履行工程项目业主的职责,实现项目目标

工程项目业主作为未来工程项目的所有和建设市场上的买方，对项目目标实现起主导作用，是工程项目的责任主体，工程项目业主应当依法认真履行自己的职责。但是，目前许多工程项目业主将应由自己完成的有关项目工作，强加给承包商、监理去做，项目运行过程中许多工作，达不到项目的需求，搞乱了建筑市场，虽经几年整顿规范建筑市场，此问题没有从分配上解决。我们已加入WTO，将有大量的国外承包商、监理涌入我国，工程项目业主认真履行职责是一个焦点问题，本在分析业主、承包商、监理关系基础上，较具体地指出了项目业主应履行的职责。

A systems approach for developing high technology products

Product development for high technology products is comprised of the three stages of assessment, development, and execution. In addition, all three stages consist of information and decisions involving technological, product, and market dimensions. This article presents a systematic approach for integrating these three dimensions by which a go—no-go decision can be reached prior to the expenditure of large amounts of funds for research and development.     

Does the Need for High Levels of Performance Curtail the Development of Creativity in Design and Technology Project Work?

This article seeks to examine the relationship that exists between the development of high order thinking such as creative and problem solving skills and the need for pupils to achieve high levels of performance in their design and technology public examinations during the final year of compulsory education in the UK.The data under discussion were collected during the final year of a four year research project when a sample of fifty 15–16 year old pupils was chosen from eight schools in the north-east of England.For the purpose of this article a further sub-sample of twenty-seven pupils [twelve pupils who achieved high marks for their project work (sixty-five percent and above) and the fifteen pupils who achieved low marks in their project work (forty percent and below) was selected.In discussing the findings, the relationship between levels of creativity, performance, personal goal characteristics, motivation and design procedures used by the pupils will be highlighted. Conclusions will then be drawn concerning the part played by GCSE Design and Technology examination project work in enhancing the development of creative, innovative thinking and problem solving skills.     

Index fund optimization using a hybrid model: genetic algorithm and mixed-integer nonlinear programming

Abstract

Index funds consist of a subset of stocks, an index tracking portfolio, included in the market index. The index tracking portfolio aims to match the performance of the benchmark index. In this paper, we propose a hybrid model for solving the multiperiod index tracking problem, which includes rebalancing concerns, transaction costs, limits on the number of stocks, and diversification by sector, market capitalization, and stock weight. Our hybrid model combines the genetic algorithm (GA) to select stocks of the index tracking portfolio and mixed-integer nonlinear programming (MINLP) to estimate its weights. Finally, we apply our proposed hybrid model to the S&P500 to find an index tracking portfolio that includes those constraints. The results show that our hybrid model is able to create an index fund whose return rate is similar to the market index with significantly lower risk.
