The social cost of through traffic: Contribution to the suburban-central city exploitation thesis

This paper deals with the conflict between local and through traffic when allocating land for transportation at the expense of residential consumption. The model developed in this paper gives the optimal allocation of land between both uses, via Pontryagin's Maximum Principle, and shows the impact of through traffic on the urban structure, on local transportation costs and on the cost of housing supply. The cost functionals are used to measure the total burden to the inner city and a connection is made to the ongoing discussion of the ‘exploitation’ thesis.

Ein empirischer Test der Annahme der permanenten Einkommenshypothese von Milton Friedman

Summary We apply the Variate-Difference-Method to yearly Austrian data from 1956 to 1975 to test the permanent-income-hypothesis byM. Fiedman.First we determe the degree of the polynomial, which is sufficient to eliminate the trend (i.e. the permanent part) from time series of disposable income. Then the permanent income variable is constructed in two alternative ways: first, as a polynomial in time and second bySheppard's smoothing formulae. Transitory consumption is identified with the residuals of the consumption function. A correlation analysis shows that, transitory income and consumption are correlated, if permanent income is determined by a trend polynomial, while this is not the case ifSheppard's smoothing formulae is used to estimate permanent income.Consumption functions are specified for total consumption, durables and non-durables and eleven sub-groups of total private consumption. The results indicate that autocorrelation can considerably be reduced by usingSheppard's smoothing formulae.     

Diffusion and scale dynamics: A case study

This paper examines the relationship between the diffusion of a major process innovation, oxygen steel-making, and the growth of plant sizes. As in some previous studies, a step-wise pattern of scale increases is observed; however, there is no stable correlation of these increases to cumulative capacity expansion, maximum plant sizes appear to have stabilized, and plants of widely dispersed capacities continued to be built as oxygen steel-making became the dominant technique, world-wide. Factors responsible for scale increase are analyzed; steadily growing equipment size, the addition of equipment to existing plants, and a wide range of minor innovations and adaptations have contributed to growth in plant capacities; in most instances, scale-up continued after the beginning of operations. It is concluded that the frequently-used concept of an optimal, or maximum feasible, plant scale remains ambiguous without reference to the specific technical and economic conditions of production systems, and that plant-size increases are fully dependent on continuing technological effort.
