We quantify marginal excess burden, defined as the change in deadweight loss for an additional dollar of tax revenue, for different taxes. We use a dynamic general equilibrium, overlapping generations model featured with heterogeneous agents and a realistic structure of corporate finance and...

A well-established principle of public finance holds that taxes impose costs on society beyond the amount of revenue government collects. Estimates vary depending on the type of tax, but the "marginal excess burden" of federal taxes most likely ranges from 14 to 52 cents per dollar of tax...

This paper analyses the efficiency of the Australian tax system using CGETAX, a large-scale, long-run CGE model designed for tax policy analysis. This follows an analysis with CGETAX of an Australian Government proposal to reduce the corporate tax rate from 30 to 25 per cent in Murphy (2016a)...

In this note we discuss how to treat taxes in a cost-benefit analysis (CBA). In particular we relate the shadow price of taxes in CBA to the concepts the marginal cost of public funds MCPF) and the marginal excess burden (MEB) of taxes. In particular we demonstrate that the MCPF is equal to one...

To help first- or second-year graduate students in economics apply their theoretical training, this paper shows how to solve a simple and intuitive computable general equilibrium (CGE) model using a calculator. Because this simplified Harberger model uses Cobb Douglas functional forms for...

The importance of capital loss offset provisions in a world of risk is well documented in the tax literature. However, the potential deadweight losses (DWLs) owing to imperfect offset has not been fully explored. This paper develops a framework whereby that investigation can be carried out, and...

Energy markets and energy-intensive industries in all EU member states - especially in Germany - are subject to a diverse set of policies related to climate change. We analyse the potential efficiency losses from simultaneous application of emission taxes and emissions trading in qualitative and...
