Applied general equilibrium models of taxation and international trade, developed by John B. Shoven and John Whalley, aim to evaluate policy options by simulating the effects of tax and trade policies on resource allocation and welfare. These models use numerical methods to analyze the impacts of policies such as corporate tax reform, value-added taxes, and trade agreements. The models incorporate production and demand functions, tax parameters, and policy variables to assess how changes in tax rates or trade policies affect economic outcomes. The paper discusses the structure of these models, the choice of functional forms, parameter selection, and the implementation of solution methods. It highlights the importance of using realistic data and elasticities to ensure the models reflect actual economic conditions. The paper also addresses the challenges of applying these models, including the need for accurate data, the complexity of policy interactions, and the limitations of numerical simulations. The authors emphasize the value of these models in providing insights into policy issues, particularly in taxation and international trade, and suggest future research directions to improve the accuracy and applicability of these models. The paper concludes that applied general equilibrium models are essential tools for policy analysis, offering a comprehensive framework for evaluating the effects of tax and trade policies on economic welfare.Applied general equilibrium models of taxation and international trade, developed by John B.
