Estimating labour supply elasticities based on cross-country micro data

A bridge between micro and macro estimates?

The Nordic model relies on high tax rates to finance an extensive welfare state. If labour supply elasticities are large, the burden of financing the model can be large even if, arguably, the practice of providing subsidised goods that support labour supply is likely to mitigate these effects. We utilise repeated cross sections of micro data from several countries, including the four major Nordic countries, available from the Luxembourg Income Study, LIS, to estimate labour supply elasticities, both at the intensive and extensive margins. The data span over four decades and include a large number of tax reform episodes, with tax rate variation arising both from cross-sectional and country-level differences. Using these data, we investigate whether micro and macro estimates differ in a systematic way. The results do not provide strong support for the view that elasticities at the macro level would be higher than the corresponding micro elasticities.
