This paper considers the identi…cation and estimation of network models with agents interacting in multiple activities. We establish the model identi…cation using both linear and quadratic moment conditions. The quadratic moment conditions exploit the covariance structure of individuals’choices in the same and related activities, and facilitate the identi…cation of peer e¤ects when exclusion re...

nowadays, audio and video media data is already facilitates generation, transmission, storage and circulation on the global scale. Audio and video data is geometrically fast as the rate of growth, the video data processing and analysis have lagged behind the pace of development in the growth of data, resulting in large amounts of data is wasted. Therefore, it becomes an urgent need for efficien...

This study investigates the impact of environmental-technological innovation and energy credit rebates on carbon reductions in Australia its global comparison. We applied a system generalized method moment (S-GMM) dataset 11 years (from 2008 to 2019) for 23 top green scheme economies. The main findings suggested that Australia's environmental are associated with reduction. Similarly, we found i...
