There is increasing interest in star recruitment policies as a means to catalyze the development of clusters in targeted research areas. While there is growing evidence of positive star-arrival effects, we know less about how relatedness to the arriving star intermediates the size of the...

We model a key step in the innovation process, hypothesis generation, as the making of predictions over a vast combinatorial space. Traditionally, scientists and innovators use theory or intuition to guide their search. Increasingly, however, they use artificial intelligence (AI) instead. We...
