Vertical Structure and Patent Pools

It is well known that patent pools can enhance efficiency by eliminating the complements problem. This paper investigates how the presence of vertically integrated firms affects the economic impact of a patent pool. Without a patent pool, the presence of integrated firms may either increase or decrease the final product price as there are two countervailing effects – reduced double marginalization and raising rivals costs. However, when there is a patent pool, vertical integration always lowers the final product price. In conclusion, the economic efficiency arguments for patent pools are enhanced when some firms are vertically integrated.     

On the asymptotically uniform distribution modulo 1 of extreme order statistics

Let (X_m)∞₁ be a sequence of independent and identically distributed random variables. We give sufficient conditions for the fractional part of rnax (X₁., X_n) to converge in distribution, as n ←∞ to a random variable with a uniform distribution on [0, 1).

Headline Impression Management in the Earnings Press Releases of TSX Venture Exchange Firms*

This paper explores firms traded on the Toronto Stock Exchange (TSX) Venture Exchange and their voluntary disclosure practices by focusing on earnings press releases (EPRs). We compare the characteristics of EPR issuers and non-issuers and investigate how the former group uses headline impression management in their EPRs to highlight firm performance. More precisely, we examine emphasis and tone management techniques in the headlines of over 1,300 EPRs by TSX Venture Exchange (TSX-V) firms. Our results show that the main determinants of the EPR disclosure choice are the achievement of positive revenue, an increasing trend in firm market value, and industry type. We find that EPR issuers reinforce and repeat positive results in the headlines of EPRs and use positive tone management to highlight positive financial performance. Our results confirm the association between firm performance and strategic placement of performance results, while illustrating that the strength of this association varies by industry and by EPR characteristics such as EPR length and numerical intensity. Overall, this paper sheds light on TSX-V firms, their disclosure practices, and potential violations of recommendations from regulators regarding avoiding exaggerated or promotional language in press releases.
