We estimate a dynamic oligopoly entry game in the early U.S. local telephone market. We observe the identities of potential entrants into local markets and therefore the waiting time of each potential entrant before it commits actual entry. To capture the feature of the data, we allow firms to...

We analyze the behavior of start-ups in e-commerce, namely on Austria's leading price-comparison-site, a multi-product environment with almost complete information. We use weekly panel data on price-quotes of digicams, Audio/HiFi-equipment and hardware. We furthermore use advanced estimation...

In contrast to previous studies, I allow chains to not only choose which markets to enter but also how many stores to open in...

This paper links empirical literature on the use of price as an entry deterring mechanism with literature on the effect of multi-market contact on competition. The analysis uses a dataset of cable TV system prices to provide evidence that incumbent cable TV firms use price to deter entry by...
