Our Boss Doesn’t Believe in Australian Zombies

But Do Australian Zombies Exist…?1. How many zombie firms are there?2. Are zombies real?3. Do zombies pose risks to the economy?
5
So What’s a Zombie?• A zombie is a firm that…
1. Has debt2. Is at least 3 years old3. Doesn’t make enough profit to cover its interest payments
• Interest Coverage Ratio (ICR) = EBIT/interest payments• We consider multiple definitions:
– Broad definition: ICR < 1 for 3 years on average– Narrow definition: ICR < 1 for 3 consecutive years
6
Zombie Data• Business Longitudinal Analysis Data Environment (BLADE)
– All businesses in Australia between 2001/02 and 2016/17– Focus on private non-financial sector– P&L and balance sheet indicators (e.g. sales, profits, interest payments)– Some caveats (e.g. no balance sheets for sole traders)
• Publicly listed company data– P&L and balance sheet indicators– Can directly identify firms– Can look at composition of debt
7
Why Do We Care About Zombies?• Financial stability: They may pose persistent credit risks if always
on the verge of insolvency• Economic stability: Zombies may clog up economic resources and
distort competition

But Are Zombies Real…? Like, Really?• Yes – most zombies are created, not born
– Evidence from the life of a zombie• No – some may be part of a `profit shifting’ arrangement
– Evidence from business enterprise groups and foreign ownership• No – zombies don’t have bank debt
– Evidence from listed company balance sheets

Fear the Working Dead
Zombie Risks to the Economy
• Zombies lower aggregate productivity– They are less productive– They make others less productive
• Zombie spillover (or infestation) effects– Crowd out economic resources (labour and capital)– The effect is strongest on young viable firms– Zombies also appear to reduce start-up rates

Zombie Conclusions• Zombies live amongst us
– More prevalent amongst companies, particularly listed companies– Most prevalent in the farm and mining sectors
• But are they real…?– Yes and no!– Most are not `born’ zombies– But many don’t have bank debt
• Zombies appear to adversely affect…– Growth in output, employment and productivity– Business entry and exit rates
