I examine the extent to which public sector outsourcing relates to public employment in OECD countries. I use new panel data on public sector outsourcing. The sample includes 26 countries over the period 2009-2015. Contrary to common expectations, the results do not suggest that public sector outsourcing expenditure was negatively related to public employment in the full sample. The relation between public sector outsourcing and public employment, however, does vary across countries. If anything, the growth in public sector outsourcing in period t-1 was positively correlated with the growth in public employment in period t. When public sector outsourcing gives rise to regrouping public employees but not reducing public employment, outsourcing may even increase inefficiencies in the public sector.

公共部门外包会减少公共就业吗？经合组织国家的经验证据

我研究了经合组织国家公共部门外包与公共就业的关联程度。我使用有关公共部门外包的新面板数据。该样本包括2009-2015年期间的26个国家/地区。与普遍预期相反，该结果并不表明在整个样本中公共部门的外包支出与公共就业负相关。但是，各国之间公共部门外包与公共就业之间的关系确实有所不同。如果有的话，t-1时期公共部门外包的增长与t时期公共就业的增长呈正相关。当公共部门外包导致重新组合公共雇员但不减少公共就业时，外包甚至可能增加公共部门的效率低下。
