Financial information
• Financial information could be key for effective taxation– On extensive margin: detect unregistered taxpayers– On intensive margin: estimate revenue and assets
• Financial information trail leveraged to detect varioustypes of income
– Multinational tax avoidance and wealthy individuals(Zucman 2014) Big debate in OECD countries (e.g. USIRS and Swiss banks)
– Domestic tax avoidance/evasion (Gordon & Li 2009)Particularly important in the absence of other info trails?
• Increasing pressure to end bank secrecy but still stronginstitution in developing countries.

Financial services taxes
• Many countries have taxed financial services -Sometimes with an “information trail” logic. (L.A. , India,Pakistan). What characterizes these policies:
– Taxing basic transactions (deposits and withdrawals) -often cash specific.
– Fill urgent budgetary needs - initially collects a lot ofrevenue (Coehlo et al 2009)
– Short-lived, justified as repealed once having served itsinformation-collection purpose. Could also be becausebehavioural responses→ zero revenue in medium-run
• But no micro-evidence on behavioral responses:– Distortions could be large in countries developing
financial inclusion.
Bachas & Jensen Bank non-secrecy: taxation and financial service use in Mexico 5/54
What this study does
• Study a policy motivated by leveraging the financialinformation trail and fighting tax evasion in Mexico
– Large informal sector and low tax/gdp ratio– Low financial inclusion given gdp
• Show important behavioral responses:– Policy led to restriction in cash deposits– Large share can be explained by substitution to other
deposits types. → Limitted loss of total deposits
• New puzzle: technology disadoption?

IDE
• Base = monthly cash deposits above threshold
• Non-cash deposits are not taxed
• Control tax: fully deductible against any other tax liability
• Financial institutions are liable for tax collection andinforming their clients (Transaction costs incurred).

IDE quotes
• El Economista, June 2009“Superando lo esperado, el Impuesto a los Depositos en Efectivo (IDE) cumple hoy
un ano. Por un lado, dejo al descubierto a casi 2 millones de posibles evasores queahora el fisco tendra que ir a buscar. Esta cifra equivale al numero de personasreportadas por los bancos al SAT, que nunca declararon el pago del Impuesto.”
• Jose Gonzalez Anaya, revenue subsecretary, July 2011:“El IDE ha sido fundamental para afinar la fiscalizacion en el pais, pues ha
permitido inscribir a unos 21,023 contribuyentes solo en el 2010 y ha permitidocorregir el Registro Federal de Contribuyentes (RFC) de otros 384,000 causantes,”
• Forum, Financial Red ”Como funciona IDE”, January 2012“Lo que deberiamos hacer todos es guardar el dinero en cajas fuertes, en casa, enun colchon, que se yo. pero sacarlo del banco”
• “Al igual que todos odio este maldito impuesto, pero he sabido de algunos tips sobretodo a los comerciantes pequenos, les recomiendo que el pago a sus probedoressea por deposito a cuentas de ellos generalmente son grandes empresas y el ide noles afecta por que lo deducen, paguen cuanto mas servicios y productos se puedaen efectivo, y solo depositen lo que verdaderamente es su utilidad ...

GDP Total deposits Tax revenue
Bachas & Jensen Bank non-secrecy: taxation and financial service use in Mexico 11/54
Macro picture
• IDE directly collected revenue only in first 2 years:I Delays in deduction and learning about IDE?I Formalization so everyone deducts?I Financial disintermediation?
• Macro levelI Tax revenue and total deposits grow faster than GDP
over period.I However cash economy and informality on the rise over
period (INEGI, OECD)I Polarization of informal and formal sector?
• Go to micro level to look deeper
Bachas & Jensen Bank non-secrecy: taxation and financial service use in Mexico 12/54
Theory: set-up
• Agent generates revenue flow Fit , which she has tostore. Three storage technologies:
– Store flow at home, c– Deposit flow at bank under cash format, d– Deposit flow at bank under non-cash format, e
• Relative gains and losses– Gain of financial usage (d , e) over cash at home c:
Safety, access to loans, bank relation, etc.– Gain of non-cash e over cash financial use d : more
efficient services, improved credit conditions (?)– Loss from non-cash e: technology adoption cost f
Bachas & Jensen Bank non-secrecy: taxation and financial service use in Mexico 13/54
Theory: introduction and repeal of IDE
• Agent maximizes: Vit = cit + βitdit + γiteit − f .1(eit > 0)
• Pre-IDE: financial usage dominates cash-economy ifmin(γit − f , βit) > 1if γit − f > βit , then adopt non-cash financial technology• IDE introduction: βi ↓ if dit > Threshold
– Decrease in d , can switches to c or e
• IDE repeal with tax reform: γt ↓ , βtγt↑ , βt unclear
– Increase in d ; some agents switch from e to d (butpotentially not complete reversal from pre-IDE).
– Assumptions on fixed cost f : incurred every period oronce?
Bachas & Jensen Bank non-secrecy: taxation and financial service use in Mexico 14/54
Theory: basic predictions and extensions
• Basic prediction: IDE-introduction leads to ↓ d , switch toc or e is governed by agent-heterogeneity in thetwo-dimensional space (βi , γi)
– Corollary of basic set-up: bunching dit = Threshold isoptimal strategy for subset of agents
• Dynamic extension: forward-looking choices– If agent faces Fit >> Threshold , possibly optimal to
repeatedly bunch d in periods t , t + 1, t + 2, ...– Agent will weigh net present value of dynamic bunching
relative to one-off net gain from switching to e: foragents with high Fit , repeated bunching is too costly
Bachas & Jensen Bank non-secrecy: taxation and financial service use in Mexico 15/54
Data
• Panel of accounts from large Mexican bank (300,000clients)
– Current focus on balanced panel of self-employed(N=82,000), most responsive to policy.
– All Deposits and withdrawals at monthly level bytransaction method
– Other financial products (e.g loans and credit cards)– Socio-demographics (locality, occupation, gender, age)
• Continuous monthly panel starting April 2011 untilOctober 2014.
• Main data issue: hard to study all effects of 2008 and2010 reforms as only have month of December of 2006,08, 09, 10.

Empirics preview
Focus on Repeal of IDE, part of 2014 Fiscal Reform:
1. Distribution over time of cash deposits:→ large reaction of cash to the reform.
2. Distributions of non-cash and total deposits:→ Substitution from non-cash to cash deposits.→ Limitted evidence of change in total deposits.
3. Study the behavior of subgroup (“bunchers”) that arerevealed preference constrained in their cash deposits.
4. Heteorgeneity and correlations with other factors

Bachas & Jensen Bank non-secrecy: taxation and financial service use in Mexico 25/54
Beyond cash deposits
• Clear evidence that IDE repeal (and tax reform?)encouraged use of cash deposit:
– Reduced frequency of small cash deposits (5-25k) anddisapreance of excess mass at threshold (15k)
– Increased frequency of medium (30-100k) andespecially of large ( > 100k ) cd.
• Substitution away from non-cash deposits or increase intotal deposits?Look at:
1. Checks, electronic, cards which are non taxable.2. Total deposits. Ex-ante effect is ambiguous:
IDE repeal ↑, Fiscal reform ↓3. Buncher’s deposit behavior post reform

Substitution and total effect
• Focus ont two moments: % deposits at 0 and %deposits above $100,000
• Slowdown in growth rate of 0 cash deposits mirrors dropin 0 non-cash deposits.
• Increase of large cash dep from 7 to 11% correspondsto drop in large non-cash dep from 40 to 36%→ Substitution across deposit technologies.
• Substitution seems to explain total deposits behavior.→ No change in total dep?

Bunchers
• Focus on group particularly affected by IDE reform:“bunchers”
– Defined as having deposited in the 13-15k c.d. -¿ Half ofthose firms constrained.
– Threshold potentially represented binding constraint.– Can think of intensity of treatment (regularility of c.d
bunching) and different comparison groups (note: nevera clean “control” group)
• Look at their behavior:– “Event studies” around reform: look at average deposits
in subsequent month following bunching month.– Regression analysis: compare bunchers to smaller
depositors and within bunchers number of timesbunching

Buncher summary
• Large increase of bunchers c.d post reform:→ bunchers were c.d constrained
• Avg $10,000 increase in c.d. explained by $10,000 dropin non-cash deposits.
• Total deposit effect seems again limitted:– Bunchers did not increase total dep by more than
smaller depositors despite increasing c.d. by more.– Only subgroup of regular bunchers increased total
deposits.

Summary and technology
• IDE repeal:– ↑ cash deposit which substitute non-cash deposits– Limitted effect on total deposits. IDE repeal cancelled by
increased information component of fiscal reform?– Bunchers were c.d constrained
• Seems IDE encouraged other deposit technologywithout a significant disintermediation effect?
• Technology puzzle: non-cash technology dis-adoptedfast after IDE repeal. → Against standard technologyadoption models.

Welfare and discussion
• Welfare evalution of IDE balances revenue gains againstreform-induced distortions• Clear evidence that IDE distorted the financial behaviour
of bank-clients– IDE repeal ↑ cash deposits and substitute away from
non-cash deposit types– But not clear if IDE had any effect on total deposits→
limitted financial disintermediation?– Difficult to study 2008 and 2010 reform: clients
disintermediated then and in 2014 reform only observebehavior of substituters?
– Are there costs to the bank from changing deposittypes? Second round effects on credit?
– Bank and clients incurred transaction and liquidity costs

Empirics preview
Focus on Repeal of IDE, part of 2014 Fiscal Reform:
1. Distribution over time of cash deposits:→ large reaction of cash to the reform.
2. Distributions of non-cash and total deposits:→ Substitution from non-cash to cash deposits.→ Limitted evidence of change in total deposits.
3. Study the behavior of subgroup (“bunchers”) that arerevealed preference constrained in their cash deposits.
4. Heteorgeneity and correlations with other factors

Heterogeneous responses
• Expect heterogeneity in response to IDE– by legal type/industry: technological variation in ability to
trade in cash?– by state/size of informal sector: variation in prevalence
of cash-economy?
• Use bunching from the 2008 introduction of IDE– Bunching intensity summary measure: number of
monthly cash deposits in bin 22.5-25k, relative tonumber of cash deposits in 25-30k bin
