Do firms manipulate earnings after winning public-private partnership bids? Evidence from China

We examine whether firms manipulate their reported earnings after winning investment project bids. China's adoption of the public-private partnership (PPP) provides a unique setting for our analysis. Using the PPP announcements to identify the firms participating in PPP projects, we find that firms conduct both accrual-based and real earnings management after PPP participation. Our findings survive difference-in-differences design with different matching methods. We document that PPP-participating firms have strong incentives to manipulate earnings because of abnormal administrative expenditure and greater short-term performance pressure than non-PPP participating firms. The auditors respond by charging higher audit fees due to the increased risk. Moreover, government subsidies relieve performance pressure and decrease the likelihood of earnings management among PPP-participating firms. Overall, this study documents the unintended consequences of PPP participation.
