We consider a supply chain with an upstream supplier who invests in innovation and a downstream manufacturer who sells to consumers. We study the impact of supply chain contracts with upstream innovation, focusing on three different contract scenarios: (i) a wholesale price contract, (ii) a quality-dependent wholesale price contract, and (iii) a revenue-sharing contract. We confirm that the rev...

The issue of power in distribution channels remains a topic of interest among both practitioners and researchers of marketing. This interest has, no doubt, been fueled by the growing power of retailers and the emergence of retail powerhouses such as Walmart. Power, in a distribution channels context, is often de…ned as the ability to appropriate a larger share of the total channel surplus. In a...

a r t i c l e i n f o JEL classification: D82 D83 Q49 L11 L12 L94 Keywords: Price pass-through Norwegian electricity market Price asymmetry Market power Transmission lag In this paper we estimate the pass-through of wholesale electricity price to the end consumer price with variable price contracts in the Norwegian electricity market using weekly data. We find substantial asymmetry when retaile...

The effects of axial stellar rotation on the wind–momentum relation (WLR) for determining the extragalactic distances are investigated. Despite the fact that the mass loss rates grow quite a lot with rotation, remarkably the effects on the WLR are found to be very small on the average. As an example, for an average orientation angle between the rotation axis and the line of sight, the luminosit...

Brighter Type Ia supernovae (SNe Ia) have broader, more slowly declining B-band light curves than dimmer SNe Ia. We study the physical origin of this width-luminosity relation (WLR) using detailed radiative transfer calculations of Chandrasekhar mass SN Ia models. We find that the luminosity dependence of the diffusion time (emphasized in previous studies) is in fact of secondary relevance in u...

Objective. Compare glaucoma medication costs between the United States (USA) and Canada. Methods. We modelled glaucoma brand name and generic medication annual costs in the USA and Canada based on October 2013 Costco prices and previously reported bottle overfill rates, drops per mL, and wastage adjustment. We also calculated real wholesale price changes from 2006 to 2013 based on the Average W...
