Consumers' switching inertia in a fictitious electricity market

Consumers in the deregulated Swedish electricity market do not switch from their incumbent supplier to the extent that would be economically beneficial. To examine potential causes for this switching inertia, a mail survey was administered to 540 Swedish electricity consumers who were randomly assigned to four experimental conditions and a control condition. Survey participants in the experimental conditions first made a choice of a supplier; then, they made choices between this alternative (their ‘incumbent supplier’) and other alternatives that differed from the incumbent supplier on price, quality of information, market share and availability of ‘green’ electricity. The results showed that lower price, higher quality of information, medium–large market share, and availability of green electricity increased switching to the alternatives to the incumbent supplier. A remaining general preference for choosing the incumbent supplier was reduced by instructions that removed feelings of loyalty and informed about the economic benefits of switching for all consumers.     

The impact of flexibility on operational supply chain planning

We study in this paper the effects of volume flexibility, delivery flexibility and operational decision flexibility in operational supply chain planning under uncertain demand. We use a rolling schedule to plan supply chain operations for a whole year. The planning horizon is 4 weeks with deterministic demand in the first week and predicted for the following 3 weeks. Using a case from the Norwegian meat industry, we compare the annual operating results of using a two-stage stochastic programming model to the deterministic expected value problem in order to discuss the impact of flexibility in the supply chain.     

Learning unit prices in a new currency

In the European Union, some citizens adapt to the Euro transition by converting the new currency to the old familiar one (‘re‐scaling’), whereas some adapt by learning the product prices in the Euro (‘re‐learning’). Employing a total of 65 undergraduates in two laboratory experiments, factors that may make such price learning difficult were identified. In Experiment 1, learning of unit prices for cellular phone calls from sequences of duration–price examples was more difficult when a fixed connection fee is added to the price of each call. Witnessing the adverse impact of price variation, Experiment 2 showed that simultaneous learning of several unit prices was less accurate than learning of single unit price.
