OxTalks is Changing
OxTalks will soon move to the new Halo platform and will become 'Oxford Events.' There will be a need for an OxTalks freeze. This was previously planned for Friday 14th November – a new date will be shared as soon as it is available (full details will be available on the Staff Gateway).
In the meantime, the OxTalks site will remain active and events will continue to be published.
If staff have any questions about the Oxford Events launch, please contact halo@digital.ox.ac.uk
Informality, Consumption Taxes and Redistribution
Joint seminar with Applied Microeconomics
What is the redistributive capacity of taxes on consumption in developing countries? We combine household expenditure data from 32 countries with theory to establish the optimal design of consumption taxes and their impact on income inequality. We use the type of store in which purchases occur to proxy for informal (untaxed) consumption. In all countries, the budget share spent in informal stores steeply declines with income. This makes consumption taxes strongly progressive as the effective tax rate rises with income. We derive optimal tax policies by extending the canonical commodity tax model to allow for informal consumption and calibrate it to our data. Contrary to consensus, our results show that consumption taxes are redistributive and reduce inequality. Moreover, once informality is considered, the widespread policy of rate differentiation across goods has limited redistributive impact. In particular, reduced rates on necessities cannot be justified on equity grounds in the poorest countries.
