While the usefulness of monitoring expectations, opinions and sentiments of economic agents is undoubted, one can argue that existing indices are based on a selected number of surveys and a low monitoring frequency resulting in a partial view of more complex dynamics. In this paper we present a web based tool based on the concept of Information Markets that can be used to aggregate expectations on policy indices and provide accurate and timely information to policy makers and policy modellers. %G English %Z TC 8 %Z WG 8.5 %2 https://inria.hal.science/hal-01637233/document %2 https://inria.hal.science/hal-01637233/file/430552_1_En_12_Chapter.pdf %L hal-01637233 %U https://inria.hal.science/hal-01637233 %~ SHS %~ IFIP-LNCS %~ IFIP %~ IFIP-TC %~ IFIP-TC8 %~ IFIP-EPART %~ IFIP-WG8-5 %~ IFIP-LNCS-9821
