Использование производственных функций с фиктивной переменной для прогнозирования добычи природного газа Газпромом в посткризисный период
This paper proposes econometric models built around a dummy-variable production function, aiming to assess future Gazprom’s natural gas production across Tyumen fields. The effort targets feasible accuracy improvements with these projections over the post-crisis period. The dummy variable is introduced into the production function here specifically for 2009 when sharp production declines were reported, to offset the missing author’s history data concerning annual averages for upstream gas capacity utilisation across Gazprom. This econometric analysis indicates that the dummy variable-based production function tended to deliver more accurate gas production outlooks for Gazprom over 2010–2013, against the earlier functions, without the dummy variable included.
