Oxford Events, the new replacement for OxTalks, will launch on 16th March. The two-week OxTalks freeze period starts on Monday 2nd March. During this time, there will be no facility to publish or edit events. The existing OxTalks site will remain available to view during this period. Once Oxford Events launches, you will need a Halo login to submit events. Full details are available on the Staff Gateway.
We compare two approaches to increasing tax revenue: tax administration and tax rates. We show that when Indonesia moved top regional firms into “medium taxpayer offices,” with high staff-to-taxpayer ratios, tax revenue more than doubled. Examining nonlinear changes to corporate income tax rates, we estimate an elasticity of taxable income of 0.579. Combining these estimates, improved tax administration is equivalent to raising top rates on all firms by 8 percentage points. On net, improved tax administration can have significant returns for developing countries.
