Optimal tax depreciation

Currently, solutions to the choice of depreciation methods for tax purposes are obtained through numerical simulation. This paper presents a simple capital budgeting technique which, in conjunction with Descartes' rule of signs, analytically derives the optimal regular depreciation method under the existing U.S. tax code. This technique is then used to determine the optimal depreciable life for short-lived assets and, finally, the analysis is extented to cover the choice of depreciation methods under the Class Life Asset Depreciation Range System.     

Exchange Rate Shocks and the Speed of Trade Price Adjustment

A quantity adjustment cost model is developed in the context of international trade along the lines proposed by Krugman (1987). The model implies that prices adjust dynamically to exchange rate fluctuations. The price adjustment speed is determined as a function of foreign demand responsiveness, the appropriate discount rate, and an adjustment cost parameter. Pass-through is incomplete and increases over time and with the speed of price adjustment. A preliminary empirical analysis finds that the speed of price adjustment from the time series by industry and then in a cross-sectional regression tentatively relates the obtained adjustment speeds to their theoretical determinants.     

Earnings Forecasts and the Information Contained in Spinoff Announcements

This study examines spinoff announcements in conjunction with financial analysts’ forecasts of earnings. The analysis shows that spinoff announcement abnormal returns are significantly related to the firm's information environment as proxieci by financial analysts’ earnings prediction errors. The findings also indicate that analysts significantly increase their short-term earnings forecasts in response to spinoffs, but do not significantly revise their long-term earnings forecasts. However, the earnings revisions are not significantly different across prediction error groups, which confirms that spinoff-related abnormal returns cannot be attributed solely to expected performance gains.     

Spatial Statistics and Real Estate

Real estate has historically employed statistical tools designed for independent observations while simultaneously noting the violation of these assumptions in the form of clustering of same sign residuals by neighborhood, along roads, and near facilities such as airports. Spatial statistics takes these dependencies into account to provide more realistic inference (OLS has biased standard errors), better prediction, and more efficient parameter estimation. This article provides an overview of the field and directs readers to the relevant literature and software.     

Pay as incentive or pay as reward? The case of Taiwan

By the 1980s, Taiwan had gradually transformed itself from an economy in which labor was plentiful, while capital was in short supply, into an economy in which a surplus of capital was accompanied by a shortage of labor. For labor economists interested in rapidly evolving labor markets, there are many intriguing questions arising out of this transition. This study explores how conventional labor market and efficiency wage theories apply during this transformation. Based on monthly data over the period 1982–2007, we examine the linear causality between pay and productivity using Geweke's [Geweke, J. (1982). Measurement of linear dependence and feedback between multiple time series. Journal of the American Statistical Association, 77, 304–313] linear feedback technique. The results indicate that both pay as reward and pay as incentive behaviors are significant in the Taiwanese economy, with pay as incentive especially strong in the manufacturing sector.     

The behaviour of unemployment and unfilled vacancies in Great Britain: a search-turnover View

Previous empirical estimates of the relationship between unemployment and unfilled vacancies in Great Britain have been obtained from a mis-specified model. In particular, past studies have attempted to estimate an equilibrium relation directly from observations which have in general been generated from disequilibrium states of the labour market. This paper presents and estimates a disequilibrium, job search-labour turnover model of the labour market, using quarterly British data, from which a static equilibrium ‘UV’ relationship can be derived. The empirical results suggest that there is no statistically significant equilibrium relationship between unemployment and vacancies in Great Britain. Consquently, the recent controversy over explanations for alleged for alleged shifts in this relationship may have been ‘much ado about nothing’.     

Wine choice and drivers of consumption explored in relation to generational cohorts and methodology

The objectives of the present study were to: (1) assess the relative importance of driver and choice factors in wine consumption behaviour, (2) assess the impact of generational cohorts upon drivers of wine consumption and wine choice factors, and (3) compare the present study's survey results relating to wine choice to those obtained by means of Discrete Choice Analysis (DCA). A geographically balanced sample of 1,229 Australian wine consumers was obtained via means of telephone survey. The results of the present study indicate that taste is the primary choice and driver factor. The present findings failed to support the empirical literature's predications relating to generational cohorts and wine consumption behaviour. Further research is required in order to assess the suitability of making and marketing wine based on generational cohort characteristics. Finally, the findings of the present study suggest that, when it comes to wine choice, a simple, cost and time effective questionnaire that utilises indirect questioning may be equally as effective as DCA. If further research continues to show congruence between results collected using both methodologies, the research community may be behoved to continue the use of traditional survey methodology.
