Online hot selling period and its impact on e-retailer’s pricing strategies

The express delivery industry is often overloaded in some hot online selling seasons, which causes consumers’ dissatisfaction. Under such a circumstance, the e-retailer can utilise two opposite strategies, i.e. to set-up either a low price with a pre-announced markdown pricing (PMDP) strategy, or a high price with a pre-announced markup pricing (PMUP) strategy for the hot selling period. As both the prices and the express service quality are different between the regular period and the hot selling period, consumers can strategically choose their purchase time, which will in turn influences the e-retailer’s pricing strategy. To investigate under what condition one pricing strategy will dominate the other, we propose a two period pricing model in which the selling season are divided into regular and hot selling period, and all consumers are assumed to be strategic. The e-retailer determines the prices over the two kinds of periods to maximise its profit. The comparison shows that a PMUP (resp. PMDP) strategy is preferred when the overloading degree in the hot selling period is slight (resp. heavy). Furthermore, we extend our model by incorporating the competition of traditional retailers.

The choice of gamma spectrometer for determining the content of 241Am

An express-estimation algorithm for determining the minimum detectable activity of ²⁴¹Am is developed. Semiconductor spectrometers manufactured by the ORTEC Company (USA) and scintillation spectrometers manufactured by the Atomtekh Company (Belarus) are compared. It is proposed to use the results to estimate the suitability of the existing inventory of measuring instruments for the radiation monitoring of territory contaminated by ²⁴¹Am. __________ Translated from Izmeritel’naya Tekhnika, No. 9, pp. 62–66, September, 2006.
