Value Capture and Policy Design in a Digital Economy

Pervasive information and communication technology (ICT), intertwined with global dispersion of supply chains, is inducing a sizable structural transformation. All the articles in this special issue highlight that even though technology is the key driver, the reactions of businesses and countries to these transformations will depend on economic, political, and social arrangements within each organization and society. The competitive landscape of the ICT industry itself is likely to remain in flux. Also in other industries, both value creation and value capture are becoming increasingly complex—and remain more favorable for the developed countries than some commonly used measures suggest. According to the prevailing economic thinking, public policies should set market-friendly “rules of the game” and then stay out of the way. In the ICT domain, technical standards, spectrum allocations, and market power associated with various types of lock-ins play crucial roles calling for more active public involvement. In particular, the dynamic aspects of competition and anti-trust policies are important yet complex. While there is limited scope for sectoral or horizontal industrial policies, this special issue provides alternative avenues for considering matrix or systemic policies emphasizing education, openness, and national competitiveness.

Fine-scale conservation planning outside of reserves: Cost-effective selection of retention patches at final harvest

Retaining forest patches at final harvest is a key conservation measure in boreal forests, but guidelines for how to increase its cost-effectiveness are lacking. In a study in boreal Sweden, we compared the cost-effectiveness of three different approaches a forest owner may use to select patches: selection based on the conservation value of patches alone, economic cost alone or both of them combined. We also compared the cost-effectiveness of six different common types of patches. Conservation value was measured as species richness of bryophytes and lichens and as structural characteristics of patches. Compared to the selection approach in which both conservation value and cost were used, cost-effectiveness was 5-14% lower when only conservation value was used, depending on how conservation value was measured. On the contrary, using only the economic cost decreased the cost-effectiveness by only 1-2%. Among the patch types, swamp forest areas and deciduous tree groups were cost-effective types to retain. However, the patch types were complementary in their species composition and all hosted unique species. We argue that, ideally, assessments of both conservation values and economic costs of retaining patches should be made prior to harvest to enable planners to make well-informed and cost-effective decisions.
