The workshop will bring together key individuals and institutions to shed light on the capabilities and limitations of existing models in the Kingdom. New oil price environment and a new policy agenda to reform, diversify and grow the Saudi economy have emphasized the need to utilize available modeling capabilities in the Kingdom. Different modeling groups have been operating to assess the impact of alternative policies on the economy. Each model has strengths and weaknesses so that a strategy of using multiple models where economists and modelers share knowledge and data would potentially provide the greatest insights for the kingdom. Furthermore, due to the cost and complexity associated with building and maintaining models, it is essential to maintain close cooperation between policymakers, economists, and modelers. The goal of this workshop is to leverage their different perspectives, discuss emerging policy questions and potential modeling gaps, and build relationships that last beyond the workshop.
