How is firm creation affected by imperfect information? Our model of rational inattention generates inefficient entry and labor misallocation, because startups make error-prone decisions. Learning decisions prospective entrepreneurs alter the effects lump-sum transfers to startups: total employment gain amplified due an unintended increase in entry, most entrants hire fewer workers, misallocati...

Accuracy of quantum process estimation is limited to noisy operations in the preparations and measurements devices. Such imperfections may lead to inaccuracies in the process reconstruction due to the fact that standard data analysis techniques presume ideal devices. Here, we provide a scheme for estimation of completely positive quantum maps acting on qubit systems using calibrated faidty stat...

Several approaches to the matter creation problem in the context of cosmological models are summarily reviewed. A covariant formulation of the general relativistic imperfect simple fluid endowed with a process of matter creation is presented. By considering the standard big bang model, it is shown how the recent results of Prigogine et alii [1] can be recovered and, at the same time their limit...
