TL;DR: In this article, the authors study the dynamics of usage intensity of second-generation cellular telephony over the diffusion curve and draw conclusions about the underlying drivers of technology diffusion by studying usage intensity.

TL;DR: In this article, a single-stage econometric approach to a standard diffusion model was proposed to estimate how the saturation level co-varies with independent factors. But the model was not applied to hypermarkets.

TL;DR: In this paper, two distinct types of pre-entry experience, core technological experience and market-based complementary experience, were studied for post-entry performance in a new industry, focusing on the fit between capabilities generated through preentry experience and the preferences of heterogeneous consumer segments.

TL;DR: In this paper, the authors consider the trade-effects of one particular standard (ISO 9000) by measuring standardization via national penetration of ISO 9000, allowing standardization to manifest via multiple (quality-signaling, information/compliance-cost, and common-language) channels, and using instrumental variable, multilateral resistance and panel data techniques to overcome endogeneity.

TL;DR: In this paper, the authors developed a structural model of demand with network effects to provide a rigorous definition of critical mass as a function of installed base, price and network effects, and found that differences in the critical mass point in different countries rest mainly on different countries' socioeconomic characteristics and the extent of competition in a country.
