Introduction Methodology and data Average impact The role of high-frequency market-making Institutional trading Conclusion
SLIDE 3 Context
◮ Renewed interest for financial transactions taxes (FTT)
since the onset of the crisis:
◮ Budget deficits ◮ Public discontent with financial sector ◮ 11 countries committed to a European FTT
◮ “Historical” evidence rather negative, but...
◮ No micro evidence ⇒ few/no links to economic
mechanisms
◮ Poor data (no counterfactuals, emerging markets, etc.) ◮ Market structure has changed (e.g. HFT)
SLIDE 4
UK Stamp Duty Revenue/Volume
SLIDE 5 This paper
◮ Evidence on the French FTT (August 2012)
◮ Stamp duty on ownership transfers ◮ Exemptions for liquidity provision ◮ Tax on domestic non-MM HFT activity
◮ Diff-in-diff with other Euronext stocks ◮ (Lit) market quality
◮ Role of MM exemption ◮ Trader types (HFT, nonHFT, Mixed)
◮ Institutional trading
◮ Impact on different clienteles ◮ Transaction costs (Implementation shortfall)
SLIDE 6 Results
◮ On average, the FTT had a negative, but muted impact
◮ Drop in volume (−10%), depth, resiliency, price
efficiency
◮ No effect on bid-ask spread and volatility
SLIDE 7 Results
◮ On average, the FTT had a negative, but muted impact
◮ Drop in volume (−10%), depth, resiliency, price
efficiency
◮ No effect on bid-ask spread and volatility
◮ Is there any role for the MM exemption?
SLIDE 8 Results
◮ On average, the FTT had a negative, but muted impact
◮ Drop in volume (−10%), depth, resiliency, price
efficiency
◮ No effect on bid-ask spread and volatility
◮ Is there any role for the MM exemption?
◮ Stocks w/ HFT MM: no impact ◮ Stocks w/o HFT MM: ր vola, price impact, spreads
SLIDE 9 Results
◮ On average, the FTT had a negative, but muted impact
◮ Drop in volume (−10%), depth, resiliency, price
efficiency
◮ No effect on bid-ask spread and volatility
◮ Is there any role for the MM exemption?
◮ Stocks w/ HFT MM: no impact ◮ Stocks w/o HFT MM: ր vola, price impact, spreads
◮ relative increase in informed trading ◮ HFT MMs able to avoid being picked off
⇒ structure of liquidity provision matters for tax design
SLIDE 10 Results
◮ To wash out the effect of HFT, we analyze institutional
trading (changes in portfolio holdings)
◮ Average impact of −20% ◮ Larger reduction in trading volume for funds with ◮ high turnover (Amihud and Mendelson (1986)) ◮ scope for asset substitution (Campbell and Froot (1994))
◮ Institutional trading costs (implementation shortfall) did
not increase significantly ⇒ confirms muted average effect on market liquidity
SLIDE 11 Literature - Theory
◮ Keynes (1936), Tobin (1978), Stiglitz (1989), Summers
and Summers (1989), Schwert and Seguin (1993)
◮ Potential Rationales for taxing (some) trading activity:
◮ Noise traders (DeLong et al. (1990b)) ◮ Speculators (DeLong et al. (1990a), Di Maggio (2013)) ◮ Intermediaries (Menkveld and Yueshen (2013)) ◮ Short-termism (Shleifer and Vishny (1990))
◮ Net effect determined by changes in market composition
◮ Kupiec (1996), Song and Zhang (2005), Bloomfield et
◮ Empirical challenge: need disaggregated evidence
SLIDE 12 Literature - Empirics
◮ Empirics: Roll (1989), Umlauf (1993), Campbell and
Froot (1994), Jones and Seguin (1997), Hau (2006), Baltagi et al. (2006), Pomeranets and Weaver (2012), Liu and Zhu (2009), Deng et al. (2014), etc.
◮ Empirical challenges
◮ no disaggregated data ⇒ harder to link to theory ◮ emerging markets or pre-2000s ◮ no X-section, no control groups
◮ Other papers on French FTT confirm average impact:
Meyer et al. (2014), Haferkorn and Zimmermann (2013), Capelle-Blancard and Havrylchyk (2013), Coelho (2014), Becchetti et al. (2013).

SLIDE 14 The policy experiment
◮ France introduced an FTT on August 1st, 2012 ◮ Restricted to French stocks with market cap ≥ 1 bln e ◮ Purchases are taxed at 0.2% (ownership transfers) ◮ Several exemptions (market making, primary market) ◮ Additional tax on HFT (traders residing in France) ◮ HFT defined as activity below a threshold of 0.5 seconds
SLIDE 15 Identification strategy
◮ Standard diff-in-diff ◮ Control group: non-French stocks traded on Euronext ◮ Identification assumption: common trends ◮ Standard checks: placebo DiD, visual inspection ◮ Allow for differences in short-/long-run impacts

SLIDE 22 Discussion
◮ Overall, the FTT’s impact is rather muted
◮ Spreads and volatility are unchanged ◮ Economically small reductions in resiliency and price
efficiency
◮ Result on depth potentially driven by reduced demand for
liquidity (e.g. Parlour and Seppi (2003))
◮ Consistent with a positive role of safeguarding liquidity
provision
◮ Market making exemption ◮ Ownership transfers

SLIDE 24 Two groups of stocks
◮ It turns out that HFT market making is heavily
concentrated in the most active French stocks
◮ Idea: Split sample into groups with and without HFT MM
% of trading volume by each category:
Trader/Group MMGroup Non-MM Group Client 18.4 30.5 Proprietary 44.7 65.0 MM 32.5 HFT 27.5 17.0 Mixed 56.4 55.8 NonHFT 16.0 27.2

SLIDE 25 ◮ AEX25 and Dutch stocks with low cancelation times
control for MM stocks
◮ Few control stocks without HFT MM > 1 bln EUR
⇒ stocks < 1 bln EUR as control for non MM stocks

SLIDE 30 Wrap-up
◮ More adverse impact on stocks without HFT MM ◮ Volume: tax-exempt market-making activity
clouds impact on volume
◮ Liquidity: higher adverse selection ◮ Two potential mechanisms
◮ Change in trading population, informed/uninformed ◮ Change in behavior or trading strategy

SLIDE 36 Discussion
◮ Support for both mechanisms
◮ HFTs and Non HFTs less impacted ⇒ ambiguous ◮ All trader types focus on more informed trades
(more short-term?)
◮ Evidence consistent both with:
◮ FTT (relatively) encouraging short-run/more informed
strategies
◮ HFT MM seem able to mitigate adverse consequences
◮ Additional evidence on composition effects
⇒ data on institutional trades

SLIDE 38 Impact on long-term investors
◮ Aggregate market activity clouds the impact on end
investors
◮ Large chunk of volume is short-term and tax-exempt ◮ Difficult to filter out the impact on the taxpayer
= end investor
◮ Use trading volume estimated from changes in portfolio
holdings (Factset) Volumef
i,t = |xf i,t − xf i,t−1| × pi,t
◮ evaluate the average effect on institutional trading
activity
◮ investigate differences across investor types (clienteles)

SLIDE 40 Impact on end investors

◮ Overall, results are consistent with a considerable effect
◮ Large variation: technical trades (e.g. Dividends)
+ different clienteles
◮ Same evidence as before, but more indirect
SLIDE 41 Discussion
◮ Consistent with viewing funds as “liquidity traders”
(from a short-term microstructure perspective)
◮ Long-term change in market composition, less trading by:
◮ high turnover funds (Amihud and Mendelson (1986)) ◮ funds with scope for asset substitution (Campbell and
Froot (1994))
⇒ impact on the informed/uninformed ratio (Bloomfield et al. (2009))

Introduction Methodology and data Average impact The role of high-frequency market-making Institutional trading Conclusion
SLIDE 43 Conclusion
◮ Overall, the FTT’s average impact is relatively muted ◮ Significant discrepancy across stocks: ◮ Adverse selection increases for less liquid stocks
◮ Stamp duty relatively discourages long-horizon
investment strategies
◮ Stocks with HFT MMs more protected against this effect
◮ Underlines the role of the MM exemption
SLIDE 44 Implications for the European FTT
◮ European FTT has much wider scope
◮ Other asset classes (bonds, derivatives...) ◮ No exemptions, all transactions
◮ Protecting liquidity provision seems important ◮ The EC expects to raise 4.8 to 6.5 bln EUR for equities ◮ We estimate that extending the French implementation to
EU-27 would raise 3.4 bln EUR
◮ A more cautious implementation need not forego too
much revenue
