In the words of Lipsey, The price effect shows how much satisfaction of the consumer varies due to the change in the consumption of two goods, as the price of one changes, the price of the other and money income remains constant. [ ].
Port of Dover: An Overview. Located 76 miles (122 kilometers) to the east of London, Dover is a major passenger cruise port (as much for cruise ferries as it is for conventional ships) that's considered England's gateway to Europe.
One route is Dover to Calais which is the most popular. This route is operated by two ferry companes: SeaFrance and P&O. Because they compete quite closely you will find they offer similar prices. With P&O the duration is about 1 hour and 30 minutes and there are up to 24 sailings per day.
