State business taxes and investment: state-by-state simulations
构建了一个框架，用于模拟州商业税变化对州内投资和产出的影响，并给出了48个州的模拟结果，对研究税收政策的经济效应有参考价值。
This article develops a framework for simulating the effects of state business taxes on state investment and output. Our simulations provide the predicted increase in investment—both in equipment and structures (E&S) and in research and development (R&D)—and the predicted increase in output for a given state resulting from a specified change in one of its three tax policies—the E&S investment tax credit, the R&D tax credit, or the corporate income tax. The simulations depend on a set of formulas linking economic parameters and state data to investment and output, all of which are reported in this article. We report results, based on our preferred set of parameters, for each of the 48 contiguous states. We also discuss alternative parameter values and explore the resulting sensitivity of predicted changes in state investment and output. Finally, we describe a simple web tool that we have made available online (www.frbsf.org/csip/taxapp.php) that allows users to insert their own preferred parameter values and simulate the economic effects for the state and tax policy of their choosing.
