State-owned enterprises (SOEs) contribute approximately 10% of the world's GDP. SOEs at one time were predicted to disappear from the economic landscape of the world, but today SOEs are growing more prevalent in the world economy. The current theories of the firm that form the pillars of the management discipline largely ignore the theoretical differences that SOEs introduce into the conceptualization of the firm. Therefore, we extend four core theories of the firm by incorporating SOEs as a mainstream (not special or marginal) organizational form into these theories. We focus specifically on property rights theory, transaction cost theory, agency theory, and resource-based theory, culminating in a research agenda with 12 testable propositions.

Water table drawdown across peatlands increases carbon dioxide (CO 2 ) and reduces methane (CH 4 ) emissions. The net climatic effect remains unclear. Based on observations from 130 sites around the globe, we found a positive (warming) net climate effect of water table drawdown.Using a machine-learning based upscaling approach, we predict that peatland water table drawdown driven by climate drying and human activities will increase CO 2 emissions by 1.13 (95% interval: 0.88 -1.50 ) Gt yr -1 and reduce CH 4 by 0.26 (0.14 -0.52) Gt CO 2 -eq yr -1 , resulting in a net increase of greenhouse gas (GHG) of 0.86 (0.36 -1.36) Gt CO 2 -eq yr -1 by the end of the 21 st century under the RCP8.5 climate scenario. This net source drops to 0.73 (0.2 -1.2) Gt CO 2 -eq yr -1 under RCP2.6. Our results point to an urgent need to preserve pristine and rehabilitate drained peatlands to decelerate the positive (more warming) feedback among water table drawdown, increased GHG emissions and climate warming.
