THE BUILT-IN FLEXIBILITY OF INCOME AND CONSUMPTION TAXES IN NEW ZEALAND

This paper provides estimates of individual and aggregate revenue elasticities of income and consumption taxes in New Zealand, based on the 2001 tax structure and expenditure patterns. Using analytical expressions for revenue elasticities at the individual and aggregate levels, together with a simulated income distribution, values for New Zealand were obtained. Results using equi-proportional income changes suggest that the aggregate income and consumption tax revenue elasticities are both fairly constant as mean income increases, at around 1.3 and 0.95 respectively. This latter estimate assumes that increases in disposable income are accompanied by approximately proportional increases in total expenditure. If there is a tendency for the savings proportion to increase as disposable income increases, a somewhat lower total consumption tax revenue elasticity, of around 0.9, is obtained for 2001 income levels. However, non-equiproportional income changes are more realistic. Allowing for regression towards the geometric mean income reduces these elasticities, giving an elasticity for income and consumption taxes combined that is only slightly above unity. Examination of the tax-share weighted expenditure elasticities for various goods also revealed that, despite the adoption of a broad based GST at a uniform rate in New Zealand, the persistence of various excises has an important effect on the overall consumption tax revenue elasticity, especially for individuals at relatively low income levels.     

Growth and Welfare Maximization in Models of Public Finance and Endogenous Growth

This paper evaluates the trade‐off between growth and welfare maximization from two perspectives. First, it synthesizes and extends endogenous growth models with public finance to compare the growth‐ and welfare‐maximizing tax rates. Second, it examines the distinct model outcomes in terms of the growth rates and welfare levels. This comparison highlights the range of trade‐offs: the growth‐maximizing tax rate can lie above, below, or on the welfare‐maximizing equivalent. We find however that even relatively large differences in growth‐ and welfare‐maximizing tax rates translate into relatively small differences in growth rates, and, in some cases, welfare levels.     

R&D Project Selection Models: An Assessment

Abstract— The R&D project selection decision is described as a process by which an intermittent stream of changes are made to lists of currently active and proposed projects. It includes generating alternatives, determining when a decision is required, collecting data, specifying constraints and criteria, and recycling. The decision is viewed as imbedded within a hierarchical, diffuse budgeting and planning process. Process characteristics such as multiple criteria whose relative importance varies over time, inherent uncertainty, and parameter interrelationships result in a highly complex decision problem. The existing normative R&D benefit measurement and project selection literature is assessed and the limitations inherent in the proposed models are determined. A number of research opportunities are identified for both methodological and empirical studies.     

Shelf Registrations and Shareholder Wealth: A Comparison of Shelf and Traditional Equity Offerings

This study examines the effect of issuing common stock on shareholder wealth under two alternative methods of registration, shelf registration under the Securities and Exchange Commission's Rule 415 and the traditional method of registering shares for immediate sale. The stock price reactions accompanying security registrations and offerings over the period from March 1982 through November 1983 are examined for over two hundred issues. A negative price reaction is observed for traditional and shelf registrations for both utility and non-utility issuers. No statistically significant difference is observed between shelf and traditional registrations. Further negative price reactions precede the offerings of these securities.     

CO‐MOVEMENT OF AUSTRALIAN STATE BUSINESS CYCLES*

We use a variety of techniques to examine the nature and degree of co‐movement among Australian state business cycles. Consistent with the results of Dixon and Shepherd (2001 ), we find that these cycles move quite closely together, with particularly strong links between the cycles of the larger states. We then seek to understand the causes of this co‐movement by using an unobserved components model to distinguish between various shocks and their transmission. Our model implies that the major source of this co‐movement in state activity is the commonality of shocks affecting state cycles. In contrast, spillovers of region‐specific shocks appear to play only a minor role in creating co‐movement, though region‐specific shocks themselves have a moderate influence on cyclical fluctuations. These findings are consistent with the results of recent studies for the United States, Canada and Europe, where common shocks have also been found to dominate regional cyclical activity.     

Conditional Earnings Conservatism and Corporate Refocusing Activities

We extend standard models of conditional earnings conservatism and adaptation value to the context of the corporate refocusing activities of UK listed companies. This analysis is interesting because refocusing activities are: (1) commonly anticipated by significant negative returns in the financial year(s) before the refocusing event; (2) typically associated with large material charges; and (3) likely to be part of a strategic plan with the internal decision preceding the formal public announcement. We complement Burgstahler and Dichev [1997] by showing how their nonlinear relation between share prices and earnings changes around refocusing events as adaptation options are exercised. Because refocusing events also involve large realized losses and major changes to firms’ strategic plans, we expect to see systematic changes in the timing relations between stock returns and reported earnings. To capture this, we show how the coefficients of Basu's [1997] model of conditional conservatism change around refocusing events.     

Dealer Networks

Dealers in the over‐the‐counter municipal bond market form trading networks with other dealers to mitigate search frictions. Regulatory data show that this network has a core‐periphery structure with 10 to 30 hubs and over 2,000 peripheral broker‐dealers in which bonds flow from periphery to core and partially back. Central dealers charge investors up to double the round‐trip markups compared to peripheral dealers. In turn, central dealers provide immediacy by matching buyers with sellers more directly and prearranging fewer trades, especially during stress times. Investors thus face a trade‐off between execution cost and speed, consistent with network models of decentralized trade.
