The book "The Indonesian Oil and Gas Industry Regulatory Reform" offers a comprehensive analysis of the introduction of competitive forces in Indonesian oil and gas regulation. It examines the challenges and strategies associated with reforming a vertically integrated network. Key aspects such as the unbundling of existing structures, non-discriminatory access to markets, and pricing for access are addressed. Additionally, the market dominance of established companies during the transition period is discussed. The work not only provides theoretical foundations but also relies on empirical evidence from other countries to support its arguments. The discussion of vertical separation compared to vertical integration in connection with liberalization is another important component of the analysis. This specialized book is aimed at students and professionals who wish to engage with the complex dynamics of the oil and gas industry in Indonesia.
