We propose the Virtual Bingo Blower (VBB) as a way to generate credible risk and ambiguity in computerized experiments …, we measure ambiguity attitudes and vary the source of ambiguity, using either the VBB or natural events. We find that the … VBB and natural events result in a similar degree of ambiguity aversion. Further, we find that, by manipulating the number …
