We examine whether social capital mitigates managerial opportunism around share repurchase announcements. We find that firms headquartered in high social capital states are associated with: (i) higher repurchase completion rates, and more so in environments where governance is weak and the potential for misleading investors is high, (ii) a smaller likelihood of information manipulation such as revealing bad news before repurchases, and (iii) lower completion rates when shares are less undervalued. By documenting that firms’ external social environments help curb managerial (...) opportunism, our study suggests that the location of headquarters facilitates trustworthiness and affects ethical considerations in corporate announcements.

An astonishingly diverse biomolecular circuitry orchestrates the functioning machinery underlying every living cell. These biomolecules and their circuits have been engineered not only for various industrial applications but also to perform other atypical functions that they were not evolved for—including computation. Various kinds of computational challenges, such as solving NP‐complete problems with many variables, logical computation, neural network operations, and cryptography, have all been attempted through this unconventional computing paradigm. In this review, we highlight key experiments across three different ‘‘eras’’ (...) of molecular computation, beginning with molecular solutions, transitioning to logic circuits and ultimately, more complex molecular networks. We also discuss a variety of applications of molecular computation, from solving NP‐hard problems to self‐assembled nanostructures for delivering molecules, and provide a glimpse into the exciting potential that molecular computing holds for the future.
