THE REINSURANCE DECISION IN LIFE INSURANCE FIRMS: AN EMPIRICAL TEST OF THE RISK-BEARING HYPOTHESIS

Several explanations have been advanced in the financial economics literature to explain the reinsurance decision in insurance firms. Prominent amongst these is the risk-bearing hypothesis which holds that reinsurance is motivated by the ability of residual claimants to effectively hedge against operational risk. Since the efficiency of risk-bearing is influenced by organisational factors, such as ownership structure and firm size, the amount of reinsurance should also vary according to the characteristics of insurance firms. This study tests empirically the hypothesis that reinsurance is related to firm-specific factors. Using 1988–1993 data gathered from New Zealand's life insurance industry, a fixed-effects covariance regression model is estimated. Consistent with expectations, the results indicate that reinsurance is associated with smaller and more highly leveraged life insurance entities, and companies with greater underwriting risk. However, contrary to predictions, it also appears that it is stocks and companies with diversified production that tend to reinsure. The risk-bearing hypothesis thus receives only partial support.     

AN EMPIRICAL INVESTIGATION OF THE EXTENT AND NATURE OF BRAND VALUATION ACTIVITY IN NEW ZEALAND

An empirical study concerned with investigating the prevalence and nature of brand valuation activity in strongly-branded New Zealand based companies is reported. Analysis of data provided by 60 companies responding to a questionnaire mailed to all New Zealand companies identified as owning recognisable brand names revealed that 15 (25%) had been involved in brand valuation activity. Support for a hypothesised relationship between the acquisitive orientation of companies and the propensity to value brands has been provided. The extent to which brand valuation is conducted as an information service to management suggests that the financial accounting orientation that has characterised much of the brand valuation debate may be somewhat inappropriate.     

AN EMPIRICAL STUDY OF A NEW CLASS OF NO-ARBITRAGE-BASED DISCRETE MODELS OF THE TERM STRUCTURE

We present empirical tests of the new no-arbitrage-based term structure paradigm in discrete time. We derive and test empirical specifications for deterministic one-factor forward rate volatility models and examine the compatibility of these forward rate volatility functions using term structure dynamics. Our estimation technique uses the generalized method of moments and is based on forward bond price deviations. We do not impose restrictions on the market price of risk, and we incorporate all available term structure information. Our data consist of four sets of pure discount bonds derived from the CRSP bond files and U.S. Treasury bill quotes.     

AN EMPIRICAL MODEL OF CAPITAL STRUCTURE: SOME NEW EVIDENCE

Using a general autoregressive distributed lag model, we estimate the longrun steady state determinants of corporate capital structure. We find that, in the long run, the leverage ratio is related positively to the corporate tax rate and firm size and negatively to future growth opportunities and stock returns. By contrast, there appears to be no relation between leverage and the corporate tax rate on a short-run year to year basis. Our results suggest that prior empirical evidence on capital structure is of questionable value precisely because of its failure to clearly separate the short-run relationship between leverage and its determinants from its long-run relationship.     

DECENTRALIZATION, ACCOUNTING CONTROLS AND PERFORMANCE OF GOVERNMENT ORGANIZATIONS: A NEW ZEALAND EMPIRICAL STUDY

This paper reports the results of a study which was conducted in five departments of the New Zealand Government and investigated the relationships between (a) decentralization and the use of accounting control systems, (b) the use of accounting control systems and district office performance, and (c) the decentralization and district ofice performance. The performance was assessed using the managers' perception of their district office (unit's) performance. Data for the study were collected from 59 district office managers using a structured questionnaire. The results indicate that an increased decentralization is associated with a greater managerial use of accounting control systems which, in turn, is associated with improved district office performance.     

CORPORATE GOVERNANCE AND CAPITAL STRUCTURE DYNAMICS: AN EMPIRICAL STUDY

Consistent with theoretical predictions, we find that both a higher level of financial leverage and a faster speed of adjustment of leverage toward the shareholders' desired level are associated with better corporate governance quality as defined by a more independent board featuring CEO–chairman separation and greater presence of outside directors, coupled with larger institutional shareholding. In contrast, managerial incentive compensation on average discourages use of debt or adjustments toward the shareholders' desired level, consistent with its entrenchment effect. The effect of corporate governance on leverage adjustments is most pronounced when initial leverage is between the manager's desired level and the shareholders' desired level where the interests of managers and shareholders conflict.     

AN EMPIRICAL STUDY OF THE DIFFUSION PROCESS OF SECURITIES AND PORTFOLIOS

The nature of the stochastic process generating the path of security prices through time plays an important role in dynamic theories of financial economics. An important consideration is the possible dependency of return variances on price levels. Using 55 years of data separated into five-year intervals, this study demonstrates that, in general, security and portfolio variances are dependent on stock price levels and the relationship is a function of portfolio size. The relationship is unstable over time. The results suggest possible detrimental effects of diversification and financial models based on log-normality are questionable.     

THE INFORMATION CONTENT AND USEFULNESS OF THE TERM STRUCTURE OF THE NEW ZEALAND BANK BILL MARKET

This paper applies the rationality concept and expectations hypothesis to test the information efficiency of the term structure of the New Zealand bank bill market. Weekly data is collected from June 1986 to November 1988. The sample period is partitioned into two subperiods by the sharemarket crash in October 1987. The empirical results suggest the presence of a time varying risk premium. This is reflected by the significantly positive volatility measure in the first subperiod and the significant interest rate level variable in both subperiods. The forecast errors correlate significantly with the growth in money supply and overseas interest rate variables. Factors other than market information inefficiency could be responsible for the significant correlation; namely the impact of the sharemarket crash on market perceptions about inflation expectations and the non-simultaneous data problem in calculating the differential costs of borrowing. Despite the rejection of the joint hypothesis, forward rates are found to have information about future spot rates beyond that contained in past spot rates, and are able to predict interest rates at least 30 days ahead.     

VISION AND PRACTICE OF E-GOVERNMENT: AN EMPIRICAL STUDY

With the internet expanding rapidly in the 1990s, most of the reform agendas of Western countries embedded information technologies in their vision for change (Heeks, 1999; and Holmes, 2001). Existing studies into the diffusion of e-government has mainly centred on the USA and exposed a limited diffusion of digital delivery systems. This paper focuses on e-government by way of the adoption and use of ICT and internet for the delivery of information and services and explores the extent to which local governments endorse the e-government agenda by looking at the strategies and policies of municipalities and their actual use of e-government for the delivery of services and information. The paper utilizes data from a survey conducted during the winter of 2005-2006, addressed to the Chief Information Officers at Italian MUs with a population greater than 40,000. The results show that despite a certain degree of endorsement in terms of strategies for e-government, the use of e-government for the delivery of services is still quite limited.     

THE SLOPE OF THE TERM STRUCTURE OF CREDIT SPREADS: AN EMPIRICAL INVESTIGATION

In this article we analyze the slope of the term structure of credit spreads. We investigate the explanatory role of interest rate, market, and idiosyncratic equity variables that the recent empirical literature highlights as important determinants of credit spread levels. This study extends the analysis and assesses its effect on credit slopes for a sample of corporate bonds. We find that these factors affect credit spreads at short and long maturities in a significantly different way. A closer inspection of the credit spread slope also reveals that it is a useful indicator of the direction of changes in future short‐term credit spreads. This evidence has important implications for the trading and risk management of portfolios of bonds with different maturities.     

THE REPORTING OF INVESTMENTS IN ASSOCIATED COMPANIES AND CREDIT EVALUATIONS: AN EXPERIMENTAL STUDY

Policymakers have been concerned with the problem of accounting for investments in associated companies. A field experiment was conducted to investigate the effects of alternative methods of recognising revenue from investments in associated companies on creditors' evaluations and decisions. Results indicate that most creditors do not adjust financial statements based on alternative methods of accounting and that different methods of accounting affect credit assessments and decisions. The implications of these findings for policymakers and creditors are discussed.
