Options on federal funds futures and interest rate volatility

This study examines the response of the spot and futures interest rates on the fed funds, Eurodollar, and Libor to the listing of CME fed funds options. With the exception of the Libor futures, the introduction of options is associated with a decrease in the conditional volatility of the interest rates in the sample. There is also evidence that the volume of options trading has a negative effect on the fed funds and the Eurodollar spot rates. In contrast, the fed funds and the Eurodollar futures rates respond positively to the volume of options trading. Overall, strong generalization of the effects of options listing and options trading across the markets is not possible. These results remain robust even after controlling for several exogenous variables including changes in the Fed's target for the fed funds rate, the TED spread, the 9/11 terrorist attacks, and day‐of‐the‐week effects.     

中国的居民收入：被忽略的低消费之解析

近年来中国政府一直在强调促进消费、平衡经济增长。尽管中国经济飞速增长，但消费在总支出中的占比很低、且不断下降，对此普遍的解释是：由于上世纪90年代中期以来，养老、医疗和教育支出的不确定性增加导致了中国居高不下的居民储蓄率。本文发现，储蓄率的增加只是消费占比下降的次要原因，重要的原因是国民收入中的居民收入占比持续下降，包括工资、投资收益和政府转移支付在内全面减少。金融业的不发达又限制了企业从银行获得营运资金贷款，这是造成工资和投资收益不断下降的主要原因。     

Information content of the fed funds rates

This study shows that the Fed Funds spot rate mostly affects the level of key interest rates while the Fed Funds futures rate tends to affect both the level and the volatility. Such effects are more concentrated on the shorter segment of the yield curve. In addition, only an unexpected change in the target rate affects both the level and the volatility of interest rates. Finally, the FOMC's increased disclosure of its policy stance has a calming effect on the volatility of key interest rates. © 2005 Wiley Periodicals, Inc. Jrl Fut Mark 25:753–774, 2005     

REDISTRIBUTIVE OUTCOMES OF SICKNESS INSURANCE ON INCOME: AN EMPIRICAL STUDY OF SOCIAL INSURANCE INSTITUTIONS

We analyzed the redistributive outcomes of sickness benefits using a typology of social insurance institutions, including four different systems, after adjusting for sickness risk factors. The aim is to empirically observe if the expected redistributive pattern of the typology could be verified whether or not considering the variations in sickness risk across the countries. Data on household earnings and sickness benefits in ten countries and for different years were taken from the Luxembourg Income Study. We also used data on labor force demography and educational attainment. Gini coefficients were used for measuring earnings inequality. Relative changes in earnings inequality for sickness benefits were predicted by social insurance institutional dummies using multiple regression analyses. Among the four different schemes, the encompassing system is found to be most redistributive, followed by basic security and targeting systems. The corporatist system has shown no significant difference from the encompassing system in redistributive outcomes.

Hedging performance of multiscale hedge ratios

In this study, the wavelet multiscale model is applied to selected assets to hedge time-dependent exposure of an agent with a preference for a certain hedging horizon. Based on the in-sample and out-of-sample portfolio variances, the wavelet-based generalized autoregressive conditional heteroskedasticity (GARCH) model produces the lowest variances. From a utility standpoint, wavelet networks combined with GARCH have the highest utility. Finally, the wavelet-GARCH model has the lowest minimum capital risk requirements. Overall, the wavelet GARCH and wavelet networks offer improvements over traditional hedging models.     

APPLICATION OF PANEL DATA MODELS IN BENCHMARKING ANALYSIS OF THE ELECTRICITY DISTRIBUTION SECTOR*

ABSTRACT ** : This paper explores the application of several panel data models in measuring productive efficiency of the electricity distribution sector. Stochastic Frontier Analysis has been used to estimate the cost‐efficiency of 59 distribution utilities operating over a nine‐year period in Switzerland. The estimated coefficients and inefficiency scores are compared across three different panel data models. The results indicate that individual efficiency estimates are sensitive to the econometric specification of unobserved firm‐specific heterogeneity. This paper shows that alternative panel models such as the ‘true’ random effects model proposed by Greene (2005) could be used to explore the possible impacts of unobserved firm‐specific factors on efficiency estimates. When these factors are specified as a separate stochastic term, the efficiency estimates are substantially higher suggesting that conventional models could confound efficiency differences with other unobserved variations among companies. On the other hand, refined specification of unobserved heterogeneity might lead to an underestimation of inefficiencies by mistaking potential persistent inefficiencies as external factors. Given that specification of inefficiency and heterogeneity relies on non‐testable assumptions, there is no conclusive evidence in favour of one or the other specification. However, this paper argues that alternative panel data models along with conventional estimators can be used to obtain approximate lower and upper bounds for companies' efficiency scores.     

The Development of Accounting and Reporting in Ghana

In this paper, we examine the economic, political, and legal systems as well as the institutional factors that influence the accounting and disclosure practices in Ghana. The impact of International Financial Reporting Standards (IFRS) on disclosure is also investigated, as Ghana has recently completed full adoption. We find that the accounting and reporting practices are significantly influenced by legal, political, institutional, and economic factors and that the regulatory environment is neither effective nor efficient due to the weak monitoring and enforcement of compliance. Although there has been some recent progress, the Companies' Code, which is the corporate legal framework of Ghana, must be updated to reflect the dynamic nature of world operations. This study advances the course of standards setters, regulators, accounting practitioners, and policymakers to improve the corporate reporting and accounting practices. Urgent measures need to be undertaken to reform and build the capacities of institutions charged with the responsibility of regulating and monitoring Ghanaian accounting and reporting practices to ensure best practices and build investors' confidence.
