A note on the high-quality advantage in vertical differentiation models
نویسنده
چکیده
It is well established in vertical product differentiation models that the high-quality firm reaps a larger profit in a two-stage quality-price game as long as the cost of quality improvement is zero or is borne as fixed cost in the first stage quality choice. This note shows that the highquality advantage may fail to hold if there is variable cost of production that is dependent on quality. JEL Classification: L13, L15

Vertical Specialization and Intra-industry Trade: the Role of Factor Endowments
In this paper, we rely on vertical differentiation models (Falvey-Kierzkowski type) to study the effects of differences in factor endowments on vertical intra-industry specialization. These effects can vary depending on the relative position of each country in terms of both its specialization in high or low qualities and its technological (dis)advantage. We focus on the Spanish intra-industry t...

متن کاملEffects of Impeller Gap on Rotor Vibration in a High Speed Centrifugal Compressor: A Numerical and Experimental Analysis (TECHNICAL NOTE)
Centrifugal compressors produce high pressure ratio and rotate at speeds. So, a tiny unbalance can produce severe vibration. In this paper, effects of impeller gap on rotor vibration in a high speed centrifugal compressor is investigated. For this purpose, a numerical and experimental analysis are carried out. The moving reference frame method in FLUENT software is used for modeling of geometri...
