Neural network pruning allows for impressive theoretical reduction of models sizes and complexity. However it usually offers little practical benefits as is most often limited to just zeroing out weights, without actually removing the pruned parameters. This precludes from actual advantages provided by sparsification methods. We propose Simplify, a PyTorch compatible library achieving effective...

The history of the mining industry is intimately connected with government regulation. As in many other countries, this reflects the fact that the Crown has reserved almost all mineral rights to itself. In many cases regulation has had adverse consequences for the sector. A notorious example was the ban on exports of iron ore in the 1960s, which depressed exploration activity and postponed the ...

The persistently high number of people reporting that they have no health insurance has precipitated a number of new comprehensive proposals to extend coverage to most Americans. Such proposals must find solutions to fundamental problems that have thus far eluded policymakers, including the role of government regulation, how much to spend, and who should pay. The experience of the 1990s suggest...

The paper tests the applicability of Whitley’ s business systems framework to the study of international differences in corporate ownership structure. In support of Whitley’ s framework we document the existence of large differences among the largest companies in 12 European nations. Furthermore we find that these differences can be partly attributed to the institutional determinants stressed b...

Antitrust litigation involving hospitals is common. This paper describes recent developments and underlying issues in antitrust law with respect to hospital-hospital relations, hospital-physician relations, and hospital-payer relations. A key unanswered question in each of these areas is how government regulation and public purchasing affect competitive markets for hospital services.
