When will knowledge holders share their knowledge with peers? Several studies suggest that norms of knowledge disclosure encourage knowledge transfer. More recently, scholars have hypothesized that norms of knowledge use may indirectly promote it. In this article, we synthesize a theoretical framework of the effect of norms of knowledge use and test its predictions by means of a field experiment involving more than 500 Italian chefs. For the literature on knowledge transfer, we confirm the importance of norms, but we also show that they are not complete substitutes for other means of protecting private knowledge. For the literature on social norms, we provide evidence of how actors assess others' propensity to conform and how this influences the intention to participate in the norm‐regulated exchange.

This paper provides a critical review of the recent empirical evidence on the links between regulations affecting the hiring
and firing of workers, labour reallocation and productivity growth. It also reviews how workers affected by labour mobility
fare and discusses policy options to support them. The upshot is that stringent employment protection has a sizeable negative
effect on labour market flows and, through this channel, hinders productivity growth. At the same time, the evidence also
shows that while greater labour market reallocation benefits many workers through higher real wages and better careers, some
displaced workers lose out via longer unemployment durations and/or lower real wages in post-displacement jobs. In this context,
reforms of employment protection should be considered as part of a comprehensive package that also includes an adequate safety
net for the unemployed and effective re-employment services. 相似文献

Summary. We consider two ascending auctions for multiple objects, namely, an English and a Japanese auction, and derive a perfect Bayesian equilibrium of the Japanese auction by exploiting its strategic equivalence with the survival auction, which consists of a finite sequence of sealed-bid auctions. Thus an equilibrium of a continuous time game is derived by means of backward induction in finitely many steps. We then show that all equilibria of the Japanese auction induce equilibria of the English auction, but that many collusive or signaling equilibria of the English auction do not have a counterpart in the Japanese auction.Received: 2 September 2004, Revised: 20 April 2005, JEL Classification Numbers:

Share-based payments are of widespread use in today's economy. Consulting firms are increasingly accepting equity compensation for their services (particularly from startups) and many governments provide fiscal incentives to support this choice. Likewise, profit-sharing licensing is an on-trend business practice by innovative firms and patent holders when transferring their technology to interested adopters. This paper unveils strategic considerations according to which an agent/seller designs its optimal policy in regard to the equity share to request in exchange for its service, technology, or trademark. The model assumes a fringe of interested users/customers differentiated by both the support they need from the seller and the value of the underlying relationship; and also holding an informational disadvantage on their own type. Given the seller's cost configuration, equilibrium outcomes entail entering a profit-sharing relationship either with the high-type customers only or with all customers. Yet, in this case, equity-based payment claims are —for rent extraction purposes— common (i.e., not differentiated) across types. 相似文献

Several asymptotic results for the implied volatility generated by a rough volatility model have been obtained in recent years (notably in the small-maturity regime), providing a better understanding of the shapes of the volatility surface induced by rough volatility models, supporting their calibration power to SP500 option data. Rough volatility models also generate a local volatility surface, via the so-called Markovian projection of the stochastic volatility. We complement the existing results on implied volatility by studying the asymptotic behavior of the local volatility surface generated by a class of rough stochastic volatility models, encompassing the rough Bergomi model. Notably, we observe that the celebrated “1/2 skew rule” linking the short-term at-the-money skew of the implied volatility to the short-term at-the-money skew of the local volatility, a consequence of the celebrated “harmonic mean formula” of [Berestycki et al. (2002). Quantitative Finance, 2, 61–69], is replaced by a new rule: the ratio of the at-the-money implied and local volatility skews tends to the constant (as opposed to the constant 1/2), where H is the regularity index of the underlying instantaneous volatility process. 相似文献
