Testing the specification of multivariate models in the presence of alternative hypotheses

In this paper we propose a non-nested hypothesis test for testing the specification of a multivariate econometric model in the presence of an alternative model which purports to explain the same phenomenon. We demonstrate that the new test statistic tends to minus the same random variable as the CPD test statistic introduced by Pesaran and Deaton (1978), provided that the truth is ‘close’ to the null hypothesis. Since the new test is simpler to compute than the multivariate CPD test, it would seem to be the procedure of choice.     

Insider ownership and dividend signals: Additional evidence from the banking industry

This study investigates the relationship between the concentration of insider ownership and the share-price response to dividend-policy changes implemented by bank holding companies (BHCs). Using a cross-industry sample, previous research (Born 1988) found that there are differences in the magnitude of the share-price response to dividend initiations which may be explained by the concentration of insider ownership of the sampled firms. We hypothesize that the concentration of insider ownership does not play a role in differences in share price for BHCs due to the presence of regulatory monitors. The results of this study support our hypothesis.     

The effects of urban transportation changes: A general equilibrium simulation

This paper uses a general equilibrium simulation model of residential land use to study the long-run effects of transportation changes in a closed city. The effects considered here include the aggregate benefits from and income distributional impact of the changes, in addition to the induced alterations in the physical characteristics of the city and in the location and modal choice of different income groups. The paper breaks new ground in its treatment of modal choice in a location theory model. An interesting point brought out in the simulations is the welfare-interdependence of different groups resulting from their spatial interaction.     

Economic valuation of product features

We develop a market-based paradigm to value the enhancement or addition of features to a product. We define the market value of a product or feature enhancement as the change in the equilibrium profits that would prevail with and without the enhancement. In order to compute changes in equilibrium profits, a valid demand system must be constructed to value the feature. The demand system must be supplemented by information on competitive offerings and cost. In many situations, demand data is either not available or not informative with respect to demand for a product feature. Conjoint methods can be used to construct the demand system via a set of designed survey-based experiments. We illustrate our methods using data on the demand for digital cameras and demonstrate how the profits-based metric provides very different answers than the standard welfare or Willingness-To-Pay calculations.     

HomeGrocer.com: Anatomy of a failure

This case study examines the initiation, financing, development, and failed merger of an ambitious online grocery retail venture: HomeGrocer.com. It highlights the risks and challenges associated with developing a revolutionary venture. Even though the HomeGrocer.com team did many things right developmentally, some key errors and unfortunate timing resulted in them expanding too quickly and running low on cash. It also forced them to make a tough strategic decision about whether to scale back operations and renege on their IPO commitments or merge with a well-funded competitor, Webvan. The case discusses lessons that can be learned from business failure.     

Effects of Earnings Forecasts and Heightened Professional Skepticism on the Outcomes of Client–Auditor Negotiation

Dismissal is a major issue for distributive justice at work, because it normally has a drastic impact on an employee’s livelihood, self-esteem and future career. This article examines distributive justice under the US’s employment-at-will (EAW) system and New Zealand’s just-cause dismissal system, focusing on the three main categories of dismissal, namely misconduct, poor performance and redundancy. Under EAW, employees have limited protection from dismissal and remedies are restricted to just a few so-called exceptions. Comparatively, New Zealand’s just-cause system delivers much more just outcomes, both in terms of remedies and punishments. Despite a few shortcomings, it should be considered as a reasonable reference for policy changes in the US.     

The Diffusion of Tax Effect Accounting in Australia

This paper examines the impact of regulation and earnings management incentives on the evolution of tax effect accounting in Australia. Following the release of the first accounting standard on the issue the method spread roughly equally throughout the mining and industrial sectors. Amendments to the standard, which loosened the recognition criteria for tax loss carry forwards, led to a significant increase in the proportion of companies (particularly industrials) adopting income tax allocation. Subsequent amendments restricting such carry forwards were associated with a significant decline in the proportion of companies allocating tax (particularly miners). We also observe differential financial statement effects between mining and industrial companies and, within both sectors, differential financial statement effects across time. Consistent with the arguments of Leppinus (1977) and Gibson (1984) the adoption of tax effect accounting is, on average, earnings enhancing in the post-DS4 period. However, in the pre-DS4 period, adoption was just as likely to reduce income for industrial companies as it was to increase it. In contrast, adoption was almost uniformly earnings reducing for mining companies. Thus something other than an earnings management hypothesis is needed to explain the voluntary adoption decision of the early (pre-DS4) adopters. We conjecture on the alternatives.
