The mobile data roaming market in the European Union is characterized by a lack of competition which is one of the main reasons for wholesale and retail prices being well above cost-based prices. In 2012, the European Commission has enacted new regulatory measures such as allowing for more players competing in the wholesale data roaming market and forcing mobile network operators to unbundle ro...

We conduct an investigation of supply chain contracts where a supplier incurs the holding cost of inventory and uses it to directly satisfy a retailer's demand. These contracts, known as " pull " contracts, have increased in popularity in practice, but have yet to be studied empirically. We investigate three pull contracts in a controlled laboratory environment: a wholesale price contract and t...

The objective of this study was to estimate genetic parameters for the weights of different wholesale cuts, using an experimental and a commercial data set. The experimental and commercial data sets included 413 and 635 crossbred Belgian Blue, Charolais, Limousin, Angus, Holstein, and Simmental animals, respectively. Univariate analyses using a mixed linear animal model with relationships were ...

I present a vertical differentiation model to assess the quality-wise strategy of an incumbent telecommunications operator under open access regimes. I show that it is always profitable for an incumbent subject to wholesale regulation to degrade wholesale quality in a non-recoverable fashion. The findings are robust to the number of competitors and the price cap level, unlike those predicted by...

This study investigates price relationships along the Norwegian salmon value chains in France, EU’s leading consumption market for salmon, and Poland, largest “processing hub.” Using a vector error correction model framework, our results indicate that determination is supplier-driven process, with export prices Norway influencing France but not vice versa. Results also suggest linkages are stro...

We employ a stylized model of the electricity industry to examine the effects of restructuring on capacity investments, retail prices and welfare, allowing for uncertain demand. We consider the following market configurations: (i) integrated monopoly, (ii) integrated duopoly with wholesale trade, and (iii) separated duopoly with wholesale trade. We find that generators install sufficient capaci...

Changes in production cost always lead to changes in wholesale and retail price. How to adjust the wholesale price, retail price and order quantity in order to derive an optimal strategy for the supplier and the retailer is one of the most perplexing problems. The purpose of this study is to develop a strategy to maximize the expected profit by simultaneously determining the adjustment ratio o...
