Our current static approach follows the bulk of public policy analysis, but we do plan to add dynamic responses. For example, https://compute.studio/PSLmodels/Tax-Brain which supports "partial equilibrium" which adjusts earnings based on user-provided labor supply elasticities. https://compute.studio/PSLmodels/OG-USA performs general equilibrium analysis, which also considers feedback loops labor and capital over decades, though it takes several hours to solve. (We've contributed to both of these open-source projects.)

These labor supply elasticities and other parameter values are debated (especially when it comes to deficits and corporate taxes), so we're starting with the less controversial results while also describing changes to labor incentives through the marginal tax rate charts.
