More than imagination: Making social and critical accounting real

We offer a critical consideration of the roles of cognitive dissonance, imagination, and critical thinking in accounting education, suggesting that all three are important elements of critical and emancipatory accounting education, but that they must be set within a context that is rooted in the “real lives” of students and teachers alike, seeking to both understand the world and to challenge it.     

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.     

A UK Empirical Test of the Larson-Gonedes Exchange Ratio Model

This paper adopts the Larson-Gonedes merger exchange ratio determination model to investigate the bargaining area in UK takeovers involving share-for-share exchanges. The model focuses on price-earnings ratios rather than share price returns and so is more consistent with practical valuation methods than other approaches. The basic model is extended for the UK to consider both cash alternative offers and mixed offers involving cash and equity consideration. The model is tested on a sample of 95 UK takeovers between 1984 and 1988 using consecutively unadjusted, FT All Share Index adjusted and beta adjusted price bases. The analysis adopts the conventional chi-square test used by Conn and Nielsen but, in addition, a new test is developed based on a Generalised Likelihood Ratio. We find that on an unadjusted price basis there is greater support for the Larson-Gonedes model in the UK than Conn and Nielsen found for the US. However, our extended model based on adjusted prices provides more cautious support. In addition, we conduct a sensitivity analysis to test the robustness of the results and provide further evidence on the wealth effects on acquiring and acquired company shareholders.     

Using proxies for the short rate: when are three months like an instant?

The dynamics of the unobservable short rate are frequently estimateddirectly using a proxy. We examine the biases resulting fromthis practice (the 'proxy problem'). Analytic results show thatthe proxy problem is not economically significant for single-factoraffine models. In the two-factor affine model of Longstaff andSchwartz (1992), the proxy problem is only economically significantfor pricing discount bonds with maturities of more than fiveyears. We also describe two different numerical procedures forassessing the magnitude of the proxy problem in a general interestrate model. When applied to a nonlinear single-factor model,they suggest that the proxy problem can be economically significant.     

Corporate Equity Ownership, Strategic Alliances, and Product Market Relationships

This paper examines long-term block ownership by corporations and performance changes in firms with corporate block owners. We also examine potential reasons for corporate ownership including benefits in product market relationships, alleviation of financing constraints, and board monitoring by corporate owners. We find the largest significant increases in targets' stock prices, investment, and operating profitability when ownership is combined with alliances, joint ventures, and other product market relationships between purchasing and target firms, especially in industries with high research and development. Our findings are consistent with the conclusion that block ownership by corporations has significant benefits in product market relationships.     

Shared organizational values: Measurement and impact upon strategic marketing implementation

The concept of shared organizational values and its impact upon successful marketing strategy implementation are discussed. The need to measure the degree to which values within the organization are shared is stressed. A method to quantitatively measure the degree of value congruency and the strength of value consistency is proposed. An exploratory, empirical study is presented in which organization values are measured and found to impact upon strategy implementation.     

Fish as the “bank in the water” – Evidence from chronic-poor communities in Congo

Small-scale fisheries in developing countries are often perceived as being a low-productivity and backward informal sector. As a result they are rarely considered in poverty reduction programmes and rural development planning. In this paper, we investigate the dual role of fish as a food and cash crop through data collected in river fisheries in Democratic Republic of Congo (DRC). Fishing in this very remote rural region of DRC is operated both by men and women, as part of a household multiple activity livelihood strategy. The data shows that poor households rely heavily on fishing for their supply of protein-rich food, in particular through women’s subsistence catches. Fishing also appears to be the main source of cash-income for the majority of households, including local farmers. Based on these findings and a review of the literature, the paper argues that small-scale fisheries can play a fundamental role in local economies, especially in remote rural areas where they strengthen significantly the livelihoods of people through their role in both food security and cash-income generation.
