Usury and Just Compensation: Religious and Financial Ethics in Historical Perspective

Usury is a concept often associated more with religiously based financial ethics, whether Christian or Islamic, than with the secular world of contemporary finance. The problem is compounded by a tendency to interpret riba, prohibited within Islam, as both usury and interest, without adequately distinguishing these concepts. This paper argues that in Christian tradition usury has always evoked the notion of money demanded in excess of what is owed on a loan, disrupting a relationship of equality between people, whereas interest was seen as referring to just compensation to the lender. Although it is often claimed that hostility towards ‘usury’ has been in retreat in the West since the protestant Reformation, we would argue that the crucial break came not with Calvin, but with Jeremy Bentham, whose critique of the arguments of Adam Smith, upholding the reasonableness of the laws against usury, led to the abolition of the usury laws in England in 1854. There has to be a role for law, whether Islamic or secular, in regulating financial relationships. We argue that by retrieving the necessary distinction between demanding usury as illegitimate predatory lending and interest as legitimate compensation, we can discover common ground behind the driving principles of financial ethics within both Islamic and Christian tradition that may still be of relevance today. By re-examining past ethical discussions of the distinction between usury and just compensation, we argue that the world’s religious traditions can make significant contributions to contemporary debate.

A Model for Studying the Effect of EMU on European Yield Curves

In January 1999, the European monetary union (EMU) was formally launched with 11 member countries. However, before May 1998 there was considerable uncertainty about who would join EMU, and whether the project would start on time. When a monetary union is formed, exchange rates between the member countries are irrevocably fixed, and yield spreads stemming from exchange-rate risk are eliminated. As a direct consequence, EMU affected the prices of long-term bonds well before 1999, but quantifying this effect can be difficult when there is uncertainty about the monetary union. We address these issues and develop a bond-pricing model which explicitly takes into account that a country may join a monetary union at a future, unspecified date. The empirical results show that a narrow EMU, consisting of Germany, France and the Benelux countries, has been priced with almost 100% probability throughout the period 1995–1998, whereas, on average, the implied probability of joining EMU has been somewhat lower for the other EU countries. However, in the period leading up to May 1998, the estimated probabilities have increased considerably for the countries that joined EMU in January 1999.     

浅议利率波动对房地产投资信托基金的影响

房地产投资信托基金(Real estate investment trusts,REITs)的高分配收益特征使其对利率波动的敏感性较强,而房地产业自身也易受利率变化的影响。1973年和2005年美国联邦局对利率的上调对REITs价格和收益都造成了重大影响,利率上调,REITs经营成本增加,REITs的总体回报率减少,直接影响到其投资价值和回报率。     

How venture capitalists respond to unmet expectations: The role of social environment

In this paper, we seek to explain venture capitalists' reactions to disappointments caused by entrepreneurs. Our basic assumption is that venture capitalists' social environment, defined as exposure to venture capital and business communities, will influence their responses to problematic situations. The results of our study suggest that venture capitalists with strong ties to their colleagues and with managerial experience are more inclined to use active and constructive approaches than venture capitalists with a lesser exposure to the venture capital and business communities.

Internal Versus External R&D: A Study of R&D Choice with Sample Selection

This paper extends previous analyses of the choice between internal and external R&D to consider the costs of internal R&D. The Heckman two-stage estimator is used to estimate the determinants of internal R&D unit cost (i.e. cost per product innovation) allowing for sample selection effects. Theory indicates that R&D unit cost will be influenced by scale issues and by the technological opportunities faced by the firm. Transaction costs encountered in research activities are allowed for and, in addition, consideration is given to issues of market structure which influence the choice of R&D mode without affecting the unit cost of internal or external R&D. The model is tested on data from a sample of over 500 UK manufacturing plants which have engaged in product innovation. The key determinants of R&D mode are the scale of plant and R&D input, and market structure conditions. In terms of the R&D cost equation, scale factors are again important and have a non-linear relationship with R&D unit cost. Specificities in physical and human capital also affect unit cost, but have no clear impact on the choice of R&D mode. There is no evidence of technological opportunity affecting either R&D cost or the internal/external decision.     

区域贸易优惠与最惠国待遇关系的冲突与法律协调——兼论我国之应对措施

区域贸易合作与多边贸易体制虽具有互补性,但彼此不能相互替代;区域贸易优惠与多边最惠国待遇实质上存在冲突,但它作为一项特殊例外存续于世贸组织体制之内。世贸组织规则确立了区域贸易优惠的合法性,从而为区域贸易提供了前所未有的发展机遇。分析区域贸易合作与多边贸易体制的关系、区域贸易优惠与世贸组织最惠国待遇的冲突,以及世贸组织规则对两者间关系的协调,有助于了解区域一体化发展进程,及时采取积极的应对措施。     

利率变动周期与商业银行绩效的实证研究

利率风险的计量、评估、监控是银行市场风险管理的重要内容。科学分析利率波动与银行收益之间关系,进而了解银行资产负债期限特征及利率风险管理水平,对实现我国商业银行资产负债管理科学决策,提升利率风险管理水平意义重大。本文采用Flannery的部分调整模型对我国上市银行的利率风险管理进行长时间窗口实证分析,结果表明:样本银行呈“借短贷长”的资产负债期限特征,利率变动期内其资产负债管理并未为银行带来实质收益,利率风险管理水平有待提高。
