The corporate income tax in an open economy

The paper begins with a brief review of the distortion literature, stressing its relation to the general equilibrium consequences of the corporate income tax. The consequences for international trade of the distortions associated with the tax are then examined, and among other things it is found that trade could reduce welfare. Finally, the implications of trade for the incidence question are examined, and it is shown that whether labor or capital bears the burden of the tax depends entirely on whether the tax is imposed in the labor-intensive or the capital-intensive industry.     

The computation of costs for price decisions

Business should compute costs in a particular way of pricing purposes. The correct cost computation varies with its purpose, though most executives still believe that an item has a true cost regardless of why it is computed.Even cost estimates made for price decisions will differ according to the type of price decision that is at issue. One finds important differences depending on whether one is estimating costs for a one-shot bid, for a promotional price offer that is to last for a short period, or for a decision concerning long-term price. Although the same basic principles would apply in all three cases, their application is different. The appropriate concept is that of “decision cost”, a very simple but powerful idea that leads to different cost conclusions than are reached by prevailing costing methods.     

Comparing bank concentration across countries

Cross-country comparisons of traditional measures of concentration, such as the Herfindahl index, are of limited use for answering normative questions such as: ‘Is the banking system too concentrated in our country?’ This paper develops a measure of concentration, essentially by normalising the Herfindahl index by a minimum feasible value for that index based on market size for each country. A formal derivation is given, and the measure is related to the mark-up of price over marginal cost for banking services. The empirical implications of the new measure are illustrated by reference to some recent studies.     

The effect of property taxes on urban areas

The effects of property taxes on urban areas are studied relative to a local wage tax. The changes in urban population and in the consumption and price of housing are determined in cities with various types of production sectors. Distortions in the composition of housing and residential density patterns are also reported. Examples are constructed to quantify the size of the changes and test whether property taxes are capitalized into land values.     

CLOTHING,AMBIENT TEMPERATURE AND COMFORT – I

Male and female students prefer much the same ambient temperature in their study-bedrooms but it is noticeable that men wear significantly more clothing than women. The same is true of Japanese students even though the preferred temperature is lower than the English students find comfortable. Overseas students of recent arrival in England tend to keep their rooms at the same temperature as the English students but wear more clothing. After a longer period in England these overseas students wear less clothing but keep their rooms significantly warmer.     

Gains in efficiency from joint estimation of systems of autoregressive-moving average processes

The paper examines gains in efficiency from joint estimation of systems of ARMA processes where cross-correlation is due to contemporaneous correlation among disturbances. The asymptotic variance of joint estimates is derived and it involves only variances and covariances among purely AR processes corresponding to the AR and MA parts of the constituent processes. Small sample gains are evaluated by Monte Carlo methods. Application of joint estimation to two short-term interest rates is shown to result in more accurate post-sample predictions relative to both univariate models and the FMP econometric model.
