Product elimination: A barrier to successful financial service sector company mergers?

The UK's financial service sector is in a process of consolidation predominately via merger and acquisition activity. Driving this process is the desire to reduce costs, increase efficiency and acquire larger customer volumes. This may result in the amalgamation of product management functions and product portfolios, leading inevitably to the need for product rationsalisation. A key controlling factor within this is the inability easily to eliminate financial service products. This may jeopardise the organisation's ability to gain the objectives that have driven the merger/acquisition action. Two key factors were seen to hinder the portfolio amalgamation process. First, the incompatibility of IT-based product management systems. Secondly, the existence of a ‘knowledge gap’ which made it harder to plan and implement effectively large-scale product elimination and portfolio amalgamation. It is likely that this will lead to higher than desired operating costs, duplication in product and service function, and loss of freedom in managing customers.     

Regoo plots as a regression diagnostic tool

Given the widespread use of regression methods in the social sciences, the recent concern with regression diagnostics is timely and important. Every diagnosis must be followed by an appropriate data analytic procedure: diagnosis and treatment are complementary and interdependent tasks. We propose a graphical diagnostic procedure for use in ordinary least squares contexts, several data analytic treatments, and illustrate them in an extant data set.     

Corporate investment and financing under asymmetric information

We develop a dynamic model of corporate investment and financing decisions in which corporate insiders have superior information about the firm's growth prospects. We show that firms with positive private information can credibly signal their type to outside investors using the timing of corporate actions and their debt-equity mix. Using this result, we show that asymmetric information induces firms with good prospects to speed up investment, leading to a significant erosion of the option value of waiting to invest. Additionally, we demonstrate that informational asymmetries may not translate into a financing hierarchy or pecking order over securities. Finally, we generate a rich set of testable implications relating firms’ investment and financing strategies, abnormal announcement returns, and external financing costs to a number of managerial, firm, and industry characteristics.     

Predictive density construction and accuracy testing with multiple possibly misspecified diffusion models

This paper develops tests for comparing the accuracy of predictive densities derived from (possibly misspecified) diffusion models. In particular, we first outline a simple simulation-based framework for constructing predictive densities for one-factor and stochastic volatility models. We then construct tests that are in the spirit of Diebold and Mariano (1995) and White (2000). In order to establish the asymptotic properties of our tests, we also develop a recursive variant of the nonparametric simulated maximum likelihood estimator of Fermanian and Salanié (2004). In an empirical illustration, the predictive densities from several models of the one-month federal funds rates are compared.     

Trade, investment and growth: nexus, analysis and prognosis

Patterns of causation between income, export, import and investment growth for 39 developing countries are examined using model selection techniques which are based on ex ante predictive ability criteria to identify the best predictive model for each country. In particular, we look at the incidence of causation and reverse causation between various economic variables which are commonly believed to lead economic growth and find that there is less reverse causation from income to these variables than previously thought. We also construct an index of global business cycle conditions and find that models of countries with high trade exposure, growth rates and investment rates tend to gain in predictive ability from the addition of this variable.     

Diverging Measures of Capacity Utilization: An Explanation

In the wake of the recent recovery in manufacturing production, the capacity utilization rates published by the Federal Reserve Board (FRB) have rebounded much more slowly than those published by the Institute for Supply Management (ISM). As a result, some observers have speculated that the manufacturing sector may have considerably less slack than is indicated by the FRB measures. Our view is that the two characterizations of manufacturing slack are not as incongruent as they first appear. This paper discusses the practical and conceptual differences between these measures of capacity utilization, and concludes that the recent divergence simply reflects the character of the latest business cycle.

Audit Fees: A Meta‐analysis of the Effect of Supply and Demand Attributes*

We evaluate and summarize the large body of audit fee research and use meta‐analysis to test the combined effect of the most commonly used independent variables. The perspective provided by the meta‐analysis allows us to reconsider the anomalies, mixed results, and gaps in audit fee research. We find that, although many independent variables have consistent results, several show no clear pattern to the results and others only show significant results in certain periods or particular countries. These variables include a loss by the client and leverage, which have become significant in comparatively recent studies; internal auditing and governance, both of which have mixed results; auditor specialization, regarding which there is still some uncertainty; and the audit opinion, which was a significant variable before 1990 but not in more recent studies.     

Book-Tax Differences and Inland Revenue Audit Adjustments in New Zealand

Abstract:  Using confidential data from US manufacturing firms' tax returns and Inland Revenue Service (IRS) audit adjustments, Mills (1998) tests, and finds support for, her hypothesis that IRS audit adjustments increase as the book-tax differences increase. We test Mills' hypothesis using confidential data obtained from the New Zealand Inland Revenue (hereafter Inland Revenue). Confidential data provide the key variable of interest, Inland Revenue's proposed audit adjustment, which is not available from public sources. These data provide the exact audit adjustment amounts, eliminating measurement errors inherent in proxy variables, and enable a temporal alignment of the book-tax differences with the Inland Revenue audit adjustments, thereby enhancing the internal validity of the relation between book-tax differences and Inland Revenue audit adjustments. Because the results of our study using New Zealand data, another time period, a more diverse set of firms, and a different institutional environment are consistent with those of Mills, we argue for the generalizability of Mills' hypothesis that proposed audit adjustments are positively related to the excess of book income over taxable income.
