A New Prepayment Model (with Default): An Occupation-time Derivative Approach

A new prepayment model is developed, which improves the modeling of the borrowers decision process by incorporating an occupation-time derivative in the valuation framework of a fixed-rate mortgage. This option-theoretic mortgage valuation model is based on stochastic house-price and interest-rate models, and requires a particularly subtle technique to incorporate a new type of occupation-time derivative, where the barrier (which activates the derivative) is in the value process and not the underlying process (as it is in standard occupation-time derivatives). This new model simulates a delay in prepayment by the borrower (beyond the time simple ruthless prepayment dictates), thus increasing the value of the mortgage to the lender, compared to the value gained using more basic models. This allows for a more advanced borrower decision process, where a rational exercise structure is retained in a modified form. Empirical evidence supports this theory, which should be beneficial for accurate mortgage-backed security pricing. The results in this paper explore thoroughly the effect on the mortgage value of a delay in prepayment by the borrower on the embedded options held and on the insurance component.

The challenge of long-term structural change

In the next 15 years, provided that aggressive rearmament is avoided, the world economy is likely to grow relatively slowly and erratically, constrained by the availability of oil. Besides energy, two other factors are challenging the established economic order—Third world industrialisation and new technologies. The author argues that the only way for a developed economy, particularly the UK, successfully to meet all three challenges is by adopting these new technologies as quickly as possible: to yield to protectionist pressures would be self-defeating since growing Third world markets will be essential to the growth of the developed world. The policy dilemma is that slow growth and rising unemployment exacerbate the rigidities of the system and slow down adjustment at a time when the need for change is at its greatest.     

Figuratively speaking: analogies in the accounting classroom

One of the foundational subjects comprising most Master of Business Administration (MBA) programs is an introductory accounting course, in which students are exposed to the study of financial and management accounting at a basic level. For many students accounting is arguably the most feared subject in the MBA program. Although some students embrace the challenge and opportunity to develop an appreciation of accounting, the part it plays in organisations, and its role in management decision-making, for others the prospect of entering the world of accounting is one fraught with apprehension. Frequently described as ‘the language of business’, for students with limited experience or prior instruction in accounting, engaging with this language is formidable, and the demystification of the accounting lexicon represents a major challenge to accounting educators. This paper advocates the use of analogies, metaphors, and similes in helping MBA students understand accounting principles and engage with the conceptual underpinnings of the discipline.     

Revising the conventional tax-effort principle

The standard methodology on tax-effort (i.e., the ratio of actual tax revenue to its optimal level) is to run a regression of actual tax revenue on countries’ specific (macroeconomic, demographic, geographical, political, social, and institutional) variables. The resulting predicted (fitted) values are then taken to represent the optimal (desired or maximum) level of tax revenue. The crucial issue of tracing out how the optimal tax revenue should be allocated to the fiscal objectives (equity, efficiency) does not seem to be of any interest to the researchers on tax-effort. The present paper argues that the standard methodology is not without faults and needs revising. We demonstrate that an optimal tax system can be safely derived from maximizing a utility function with respect to (in)direct tax rates. The manipulation of the first-order conditions, using a novel mathematical module, leads to an infinite number of optimal direct–indirect tax rates. The selection of the optimal mix of these tax rates is dependent on the country-specific households’ preferences over equity/efficiency, as they are formulated by voters’ volition in election periods. A simulation procedure helps understanding how the optimal tax revenue is chosen and how it can be optimally allocated to fiscal objectives, in the context of a panel data set including a large number of developed and developing countries. Throughout our text, the optimal tax revenue is defined as the sum of the products of the optimal (in)direct tax rates and their corresponding tax bases. In the simple Arrow–Debreu economy, the above sum is shown to be equal to the difference between income and consumption.     

Greasing the wheels of rural transformation? Margarine and the competition for the British butter market

This article considers an example of the impact of a new good on producers of close substitutes: the invention of margarine and its rapid introduction into the British market from the mid‐1870s. This presented a challenge to the traditional suppliers of that market, butter producers from different European countries. We argue that the capacity to react quickly to the appearance of this cheap substitute by improving quality and establishing product differentiation was critical for the fortunes of butter producers. This is illustrated by a discussion of the different reactions to margarine and quality upgrading in Ireland, Denmark, and the Netherlands. A statistical analysis using monthly data for Britain from 1881–7 confirms that margarine had a greater impact on the price of poor quality butter than that of high quality butter, presumably because it was a stronger substitute.     

How to grow a brand: Retain or acquire customers?

While customer acquisition is clearly important for new brands, mature brands are often said to rely on defection management for maintenance and growth. Yet the theory to support this approach has been subject to very little empirical investigation. How do brands actually increase the size of their customer base? Through superior acquisition or by reducing customer defection? Or some mixture of both? Conversely, do brands decline through deficient acquisition or excessive defection? This work analyzes changes in ‘first brand loyal’ customers to answer these questions, using a combination of panel data on the prescribing behavior of doctors and a cross-sectional tracking survey for residential finance. This study is the first research to compare defection and acquisition against stochastic benchmarks for customer churn under stationary conditions. The results are surprising: for both growth and decline, unusual acquisition plays a much stronger role than unusual defection. This finding demonstrates that acquisition has been under-rated in the past, and implies that prospect management is at least as important as defection reduction. A simulation shows that unusual acquisition also accounts for far more improvement in profit than does unusual defection.     

The inter‐relationship between capital structure and dividend policy: empirical evidence from Jordanian data

The study investigates the under‐researched relationship between capital structure and dividend policy in emerging markets with regard to the Jordanian market. The empirical analysis focuses on the estimation of both single equation models and structure equation models using the reduced form equations to examine the joint determinants of capital structure and dividend policy. The study investigates whether capital structure and dividend policy theories can explain the financial decisions in emerging market such as the Jordanian market. Namely, the study examines agency theory, signalling theory, pecking order theory and bankruptcy theory. The results indicate that there is a positive relationship between debt‐to‐asset ratio on the one hand, and asset tangibility, profitability, market‐to‐book, liquidity, firm size, and industry classification on the other hand. Also, there is a negative relationship between debt‐to‐asset ratio and profitability. In addition, there is a positive relationship between dividend payout ratio on the one hand, and profitability, asset tangibility, market‐to‐book and industry classification on the other hand. Finally, the results of the reduced form equations show that capital structure and dividend policy have the following common factors: profitability; asset tangibility; market‐to‐book; industry classification; and limited evidence of institutional ownership. Therefore, the determinants of capital structure and dividend policy in emerging markets such as the Jordanian market share the same set of suggested factors with the developed markets.     

Cultural and socioeconomic constraints on international codes of ethics: Lessons from accounting

This paper provides a framework for the examination of cultural and socioeconomic factors that could impede the acceptance and implementation of a profession's international code of conduct. We apply it to the Guidelines on Ethics for Professional Accountants issued by the International Federation of Accountants (1990). To examine the cultural effects, we use Hofstede's (1980a) four work-related values: power distance, uncertainty avoidance, individualism, and masculinity. The socioeconomic factors are the level of development of the profession and the availability of economic resources. We evaluate the applicability and relevance of the accounting guideline, and discuss the implications for accounting and other professions.Jeffrey R.
