In the Netherlands, vacancy of retail properties is a relatively new problem in contrast to vacancy in the office market, which has been on the agenda for years. The main reason for this development is the web shop-march. The service economy is no longer bounded from nine to five while opening hours of physical shops still are. By gaining insight in consumer preferences and behavior concerning extended shop opening hours, potential for inner cities to compete with online shops will increase. Resulting in more viable and profitable retail surface.
