Last May I wrote about the European March Toward Open Data. A Finnish study had found 15% better economic performance in countries with open data policies compared to those trying to recover their costs. Based on that finding, Finland had begun making their geodata available free of charge to all users.
I neglected an important issue. The growth came from small and medium enterprises (SMEs). Lower costs allow SMEs to develop new GI-based products and services. Large firms, able to pay full fees, didn’t do anything different when data became cheaper. See Does Marginal Cost Pricing of Public Sector Information Spur Firm Growth?
