| Abstract: | We explore the indirect network effect in the market for home video games. We examine the video game console makers’ strategic choice between increasing demand by lowering console price and by encouraging the growth of software variety. We also explore the existence of an applications barrier to entry in the console market, and find that there is little evidence for such a barrier. Finally, we assess the applicability of the model to out-of-sample situations, to look at whether our model and previous similar models can generalize to other markets for purposes of marketing or antitrust inquiry. We find that the model generalizes reasonably well to the Japanese market for the same generation of gaming systems, but poorly to previous generations in the US market. |

| Abstract: | In Portugal, the telecommunications incumbent o®ers broadband access to the Inter- net, both through digital subscriber line and cable modem. In this article, we estimate the impact on broadband access to the Internet of the structural separation of these two businesses. We use a panel of consumer level data and a discrete choice model to estimate the price elasticities of demand and the marginal costs of broadband access to the Internet. Based on these estimates, we simulate the e®ect on prices and social welfare of the structural separation. Our results indicate that the structural separation would lead to substantial price reductions. For broadband clients, on average, each household would save 3:37 euros per month, or 14% of the current price levels. Overall, on average, each household would save 2:73 euros per month, or 14% of the current price levels. We test the robustness of our results in terms of: (i) the estimates of the demand elasticities, (ii) the strategic behavior of the ¯rms, and (iii) the market share estimates. There is no evidence of collusion. |

| Abstract: | In this paper, we study the dynamics of usage intensity of second-generation cellular telephony over the diffusion curve. We address two specific questions: First, does information about usage intensity over time allow us to draw conclusions about the underlying drivers of technology diffusion? Second, what effect does the existence and penetration of previous generations and other networks in the same generation on network usage intensity? Using an operator-level panel covering 41 countries with quarterly data over 6 years, we find that heterogeneity among adopters dominates network effects and that different technological generations are complements in terms of usage, but substitutes in terms of subscription. |
