In this paper, we explore the reasons for the survival of some Internet start-ups within the framework of organizational adaptation, and propose that the performance of a firm in a fast-changing environment is related to the adaptability of its business model. Our motivation is the lack of empirical work on firm adaptation in a hyper-competitive environment. We use the event-study methodology t...

IFC Inside: Retrofitting Languages with Dynamic Information Flow Control

Ca2+ lightning conveys cell-cell contact information inside the cells.

Cells communicate with each other to form organized structures by cell-cell adhesion and cell-cell repulsion, but it remains to be clarified how cell-cell contact information is converted into intracellular signals. Here, we show that cells in contact with neighbouring cells generate local transient intracellular Ca(2+) signals (Ca(2+) lightning). Ca(2+) lightning was observed near cell-cell co...

Decoding Inside Information

Exploiting the fact that insiders trade for a variety of reasons, we show that there is predictable, identifiable “routine” insider trading that is not informative for the future of firms. A portfolio strategy that focuses solely on the remaining “opportunistic” traders yields value-weighted abnormal returns of 82 basis points per month, while abnormal returns associated with routine traders ar...
