Taxes and transfers reduce inequality in disposable income relative to market income. The effect varies, however, across OECD countries. The redistributive impact of taxes and transfers depends on the size, mix and the progressivity of each component. Some countries with a relatively small tax...

Three main approaches can be used to assess infrastructure performance. The first employs macro-econometric techniques to estimate the impact of the existing infrastructure capital stock on growth and to infer its growth-maximising level. This approach neglects the impact of infrastructure on...

Despite the economic importance of the road transport sector, there is no systematic cross-country evidence on the sector’s efficiency. This paper develops a conceptual framework for analysing the social efficiency of the road transport sector, including non-market inputs – such as travel...

The recent economic crisis has provided a stress test for the vulnerability of social institutions. This paper assesses the vulnerability of social institutions in light of the current crisis, and surveys past episodes, when social institutions faced similar challenges. Public pay-as-you-go...
