Enhancing the Accessibility of Accounting and Business Archives: The Role of Technology in Informing Research in Accounting and Business

The application of advanced digitization technologies to accounting and business archives has created new opportunities for accounting and business historians. The joint American Accounting Association and European Accounting Association Task Force (2006–2010) that examined digitization confirmed this. This paper explores these opportunities, along with some attendant challenges and cautions, with reference to the digitization of two significant archives located in Australia. The first is the archive of CPA Australia, a professional accounting association that has its beginnings in 1886 and which today has over 132,000 members. The second is the archive accumulated by the pre‐eminent accounting scholar Raymond Chambers during his long and extraordinarily productive tenure at the University of Sydney. Studies of surviving business records, biography and institutional history provide examples of scholarship that is enabled by digitization technology and which has the capacity to inform contemporary issues and debates.     

Local authority budgets 1981

Information technology has tremendous potential as a tool of management in developing ever more sophisticated ways of handling management information. But it can never do away with the need for management, the process of using human ingenuity and creativity to come up with practical solutions to real problems. There is a danger that the technology could be used to diminish the human dimension of management.     

Simple formulas for standard errors that cluster by both firm and time

When estimating finance panel regressions, it is common practice to adjust standard errors for correlation either across firms or across time. These procedures are valid only if the residuals are correlated either across time or across firms, but not across both. This paper shows that it is very easy to calculate standard errors that are robust to simultaneous correlation along two dimensions, such as firms and time. The covariance estimator is equal to the estimator that clusters by firm, plus the estimator that clusters by time, minus the usual heteroskedasticity-robust ordinary least squares (OLS) covariance matrix. Any statistical package with a clustering command can be used to easily calculate these standard errors.     

Estimating unobservable valuation parameters for illiquid assets

A problem that often arises in applied finance is one where decision‐makers need to choose a value for some parameter that will affect the cash flows between two parties involved in the operation of an illiquid asset. Because the values of the cash flows also depend on various unobservable parameters, identifying the value of the policy parameter that achieves the desired allocation between the parties is no simple task, often resulting in disputes and the invocation of ad hoc approaches. We show how this problem can be solved using an extension of the well‐known ‘implied volatility’ technique from option pricing, and apply it to the determination of equilibrium rental rates on ground leases of commercial land.     

THE EFFECT OF MARKET PROXY REBALANCING POLICIES ON DETECTING ABNORMAL PERFORMANCE

In this paper, effects on the measured abnormal performance of test portfolios are compared against market proxies having the same or different rebalancing policies. Results show that the common practice of comparing buy-and-hold test portfolios with equally weighted market proxies produces lower Jensen [ 7 ] alphas and lower alpha t-values. Comparing buy-and-hold test portfolios with value-weighted market proxies produces higher portfolio betas and alphas, but lower alpha t-values. Finally, comparing buy-and-hold test portfolios with buy-and-hold market proxies produces the most powerful tests of abnormal performance.
