This paper proposes several statistical tests for finite state Markov games to examine whether data from distinct markets can be pooled. We formulate homogeneity tests of (i) the conditional choice and state transition probabilities, (ii) the steady-state distribution, and (iii) the conditional state distribution given an initial state. The null hypotheses of these homogeneity tests are necessary conditions (or maintained assumptions) for poolability of the data. Thus rejections of these null imply that the data cannot be pooled across markets. Acceptances of these null are considered as supporting evidences for the maintained assumptions of estimation using pooled data. In a Monte Carlo study we find that the test based on the steady-state distribution performs well and has high power even with small numbers of markets and time periods. We apply the tests to the empirical study of Ryan (2012) that analyzes dynamics of the U.S. Portland cement industry and assess if the data across markets can be pooled.

“…Only one study that uses OECD and ITU data for NGA adoption finds insignificant results (Samanta et al, 2012). Whereas all these studies use aggregate country level data, one study makes use of Japanese data (Minamihashi, 2012) at the municipal level and also finds that unbundling regulations have a negative impact on entrants' incentive to invest in NGA infrastructure (while leaving the incumbents´ investment unaffected). A recent study by Bourreau et al (2017) employs panel data for French municipalities.…”

“…Minamihashi (2012) has examined whether unbundling regulations imposed on the Japanese incumbent operator have prevented entrants from self-deploying new broadband infrastructures, using municipal level data from 2005 to 2009. The author has found that unbundling regulations hinder entrants from investing in their own NGN infrastructure.…”

How to Fill the Digital Gap?The ( AbstractThis paper provides evidence on the migration from an "old" technology to a "new" technology, taking into account the impact that regulatory interventions on the old one might have on the incentives to invest and adopt the new one. This analysis has been applied to a sample of EU27 countries using panel data from 2004 to 2014 on the adoption, coverage and take-up rate of ultra-fast broadband infrastructures, whose development is one of the flagship initiatives of the Europe 2020 programmes.Results show that a 1% increase in the regulated price to access the old technology increases the adoption and the investment on the new broadband technology by ~0.45% and ~0.47%. These effects are not homogeneous across countries and are weakened in Eastern European countries, where the existing old broadband infrastructures are less developed than in the rest of Europe. It has also been shown that the access price to old networks negatively affects the take-up rate of the new technology-based services, thus calling for the need of more specific and complementary demand side policy incentives to enhance service adoption.~ 1 ~
