The Impact of Telecommunication Technologies on Competition in Services and Goods Markets: Empirical Evidence
实证发现，电信技术的更密集使用和更广泛采用显著提升了服务与商品市场的竞争水平，结果支持电信技术降低进入和搜索成本的观点。
Abstract In this paper, we empirically show that a more intensive use and wider adoption of telecommunication technologies significantly increases the level of product market competition in services and goods markets. Our results are consistent with the view that the use of telecommunication technologies can lower the costs of entry and search. These findings are robust to various measures of competition and a wide range of specification checks.
