THERMOLUMINESCENCE DATING OF MATERIALS WHICH EXHIBIT ANOMALOUS FADING

This article reports a generalised and systematic approach to the thermoluminescence (TL) dating of samples which suffer from anomalous fading. We hypothesise that the TL signal from each mineral phase is composed of a stable and an unstable portion. The decay of the unstable TL is accelerated thermally, until only stable TL remains. The dating is then carried out on this stable signal. The results, on four known-age, coeval samples, exhibiting gross anomalous fading (25-50% loss over a few days), indicate that many, if not all, samples may successfully be dated with this approach.     

TRANSPORTATION RATES AND LOCATION OF THE FIRM: A COMPARATIVE STATIC ANALYSIS*

ABSTRACT This paper examines the role of the structure of transportation rates in the Weber-Moses triangle model. It shows that, in Zeigler's analysis, the appearance of the price elasticities of demand for inputs actually vanish by a simple application of the envelope theorem. Applying comparative statics analysis, we show when transportation rates are a function of quantity and distance, the assumptions that the production function is homogeneous of degree one and the transportation rates elasticities with respect to quantity and distance are constant are not sufficient to insure that the optimum location is independent of the level of output. This result is significantly different from that obtained by either Miller and Jensen or Zeigler.     

INTERRELATIONAL INCOME-DISTRIBUTION MULTIPLIERS FOR THE WEST VIRGINIA ECONOMY*

ABSTRACT. This paper presents a set of Miyazawa interrelational multipliers, which measure how direct changes in the income of each income bracket result in indirect and induced income changes in all other brackets. The multipliers have been calculated for a 9-by-9 pairing of income brackets for West Virginia in 1982. Their estimation is based on a combination of survey and nonsurvey data in three forms: a 1982 West Virginia input-output table, a multisector income-distribution matrix, and an income disaggregated consumption matrix. The paper illustrates the usefulness of the multipliers by showing how they provide insight into the viability of trickle-down theory and the incidence of regional development policy.
