The 52-week high,momentum, and predicting mutual fund returns

George and Hwang (J Finance 59:2145–2176, 2004) have shown that the 52-week high share price carries significant predictive ability for individual stock returns, dominating other common momentum-based trading strategies. Based upon their results and other methods, this paper examines and compares the performance of three momentum trading strategies for mutual funds, including an analogous 1-year high measure for the net asset value of mutual fund shares. Strategies based on prior extreme returns and on fund exposure to stock return momentum are also examined. Results show that all three measures have significant, independent, predictive ability for fund returns. Further, each produces a distinctive pattern in momentum profits, whether measured in raw or risk-adjusted returns, with profits from momentum loading being the least transitory. Nearness to the 1-year high and recent extreme returns are significant predictors of fund monthly cash flows, whereas fund momentum loading is not.     

Who Cares about Skills? The Impact and Limits of Statutory Regulation on Qualifications and Skills in Social Care

This article examines the impact of statutory regulation on qualifications and skills in the social care sector in the UK. It draws on various sources and a set of case studies, first carried out in 2003 and replicated in 2008. The analysis shows that the advent of the statutory regime has had a positive effect on the volume of training and qualifications in the sector. However, few organizations have combined training with a broader set of human resource management practices of the kind required for the establishment of a high‐performance work system. This constitutes one of the continuing limits to further skill development. Changes in the regulatory regime risk losing benefits that have been gained.     

Import elasticities and the external constraint in Mexico

The paper estimates and analyzes an equation for intermediate imports in Mexico during the 1988–2006 post-liberalization period. While some results are obtained from Johansen's VECM model, most of the analysis is carried out within an Error-Correction ARDL framework, following the bounds testing approach of Pesaran et al. (2001). Besides showing that an aggregate equation for intermediate imports can be satisfactorily estimated, the paper focuses on two specific results. First, exports have a very significant effect on imports, and failure to control for this effect (as in most previous studies) can yield misleading results, like an over-estimation of the output elasticity of imports. Second, the response of imports to variations in the real exchange rate has fallen over time, presumably because of the rising share of maquila in Mexico's export basket and the increasing “vertical specialization” of non-maquila export production. Some implications of the estimation results are briefly discussed, making reference to the possible external constraint on Mexico's economic growth.     

Textbook Treatments of the Financial Market in the IS-LM Model

Intermediate macroeconomics textbooks introduce financial markets into the IS-LM analysis but typically as a beginning-of-period consideration. Here the financial market is introduced in an end-of-period model.     

Statistical Independence and Fractional Age Assumptions

Abstract

This paper considers in some detail the issue of statistical independence of the curtate future lifetime and the fractional part of the future lifetime of a general status.

Statistical independence is often employed in actuarial contexts, primarily because it leads to simple relationships between quantities of interest and statistical information that is of a discrete nature, such as a life table. The uniform distribution of deaths (UDD) assumption is the most commonly used because of its simplicity and intuitive appeal, but it can be somewhat restrictive. For example, all deaths or withdrawals may be assumed to be at a particular point in the year such as the middle; assumptions of this type are often made in a multiple decrement context. This paper attempts to unify these assumptions and extend their applicability in an actuarial context.

The conditions for independence need to be stated carefully, and the last-survivor status is cited as an example in which failure to do so can lead to erroneous conclusions.

The fractional independence (Fl) assumption is defined, and it is demonstrated that many of the formulas for life table functions that hold under the more restrictive UDD assumption are extended easily to the general Fl case. The simple relationship under UDD between insurances payable on other than an annual mode and those payable at the end of the year of death is extended to the Fl case as well. These results are then used to obtain results for annuities and reserves, again generalizing UDD relationships. It is then demonstrated that many contingent probabilities in the multiple life context are exactly the same under the Fl assumption as under the more restrictive UDD assumption. Finally, a very general result that holds in the multiple decrement context is shown to hold under the Fl assumption.     

Technical Progress and Product Reliability under Competition and Monopoly

Technical progress lowers costs and prices but appears to have an ambiguous effect on product reliability. This paper presents a simple model which explains this observation. Copyright © 2013 John Wiley & Sons, Ltd.     

Performance Reporting under Fair Value Accounting

Abstract

This paper compares performance measurement under fair value accounting vs. U.S. GAAP accounting. As illustrated in the paper, the main difference between fair value accounting and U.S. GAAP accounting lies in the treatment of gains and losses on both assets and liabilities. Fair value accounting would report all gains and losses on both assets and liabilities in the period in which they arise. U.S. GAAP on the other hand, recognizes gains and losses over the life of the block of business (or at the time of a transaction). When net gains and losses on assets and liabilities are immaterial, the pattern of earnings under both systems can be quite similar. However, If a company is generating significant gains or losses on its net book of business (such as in the case of an asset/liability mismatch), fair value accounting will reveal this much sooner than U.S. GAAP. When the full impact of its actions (including gains and losses) is reported in the current period, management is in a better position to understand how the value of the company is changing and adjust its decisions accordingly. This is one of the main reasons for moving to a fair value system and is expected to be a major benefit if fair value accounting is ultimately adopted.     

Use of select mortality tables for forecasting the number of recipients of different types of Pensions

At present, planning of the number of pensioners during execution of the budget of the RF Pension Fund is carried out on the basis of analysis of the state statistical accounting data on the population number and mortality. Construction of mortality tables by categories of pensioners on the basis of summarizing the data available at the RF Pension Fund and further use thereof during planning of the budget will permit achieving both forecasting of the number of pensioners by means of moving of ages and planning of expenditures for payment of pensions and benefits as a whole with higher accuracy.
