Introduction
Cashless economy
Economy in which different payment methods have the same sets of barriers (are not discriminated against)
Interchange fees
Key tariffs in retail payments market, which is usually paid by acquiring bank to issuing bankupon every transaction. Interchange fees affect fees of all other market participants
National Payment System (NPS)
Payment system that is established for uses in a particular country or region. Could be implemented by bank association (JCB), commercial firm (EFTPOS, Bancontact) or regulator (Unionpay, NSPC)
Types of regulatory interference into retail payments market considered here:
• Interchange fees regulation
• Implementation of NPS3
Motivation
Idea: Empirically test the correlations between government interference (interchange fee regulation and NPS creation) into retail payments market and the market development (volume of cashless transactions)
Main Additions:
▪ Empirical evidence of consequences of government intervention in retail payments market development
▪ Cross-country analysis
Contribution: Empirical correlation between government intervention and retail payments market development allows understanding the directions for optimal stimulating policies development

Theoretical framework (1/2)
Interchange fee regulation effects
Lower interchange fee as a result of regulation leads to lower profit of payment systems => lower individuals’ benefits => lower incentive to use cards payments => in terms of welfare inefficient regulation (Rochet & Tirole, 2011; Krivosheya & Korolev, 2016, 2017; Krivosheya, 2018, 2020; Bedre-Defolie & Calvano, 2013)
Lower interchang fee => lower merchants’ costs => more merchants can afford accepting cashless payments => more card transactions => stimulation of cashless payements (Gurthie & Wright, 2007; Vickers, 2005; Rochet & Tirole, 2011)
Low interchange fee => lower merchants’ costs => lower market prices => stimulation of all types of purchases (Weiner & Wright, 2005; Evans. 2011; C. Arango & Taylor, 2008; Rochet & Tirole, 2011; Bolt & Mester, 2017)

Theoretical framework (2/2)
NPS implementation effects
• Better introduction into government payments (e.g., Multibanco) (Kayalidereden& Cetiner, 2018; Chaplin et. all, 2014)
• NPS serves as operator of POS terminals => more possibility to use cashless payment (e.g., Unionpay) (Yip & Yao, 2015)
• Targeting previous non-users (e.g., Rupay & Troy) (Kayalidereden & Cetiner, 2018; Gupta, 2017)
• Providing cards without fees mainly for social transfers (e.g., NSPC) (Krivosheya & Korolev, 2016; Krivosheya, 2018; Krivosheya, 2020)

Hypotheses
H1:
▪ National payment systems introduction correlates with higher cashless payments usage, i.e. volume of cashless transactions.
H2:
▪ Interchange fee regulation (cuts) correlate with higher volume of cashless transactions.

Distribution of countries (number of countries on the chart):
Model
• Volumeit is the logarithm of volume of transactions in country i at time t
• Macro factorsit is the vector of control variables of macroeconomic factors (e.g., GDP per capita, population size, urbanization rate, government efficiency, etc)
• Market specific factorsit is vector of control variables of retail payments market controls (e.g., number of ATMs, number of POS terminals, etc)
• Governmentit is vector of two explanatory dummy variables: interchange fee regulation (1 if interchange fee was regulated; 0 otherwise) and implementation of NPS (1 if NPS is introduced & operating; 0 otherwise)
• ε is vector of robust standard errors
Models for debit and credit cards markets are observed separately due to market specificsEstimation method: Arellano-Bond estimation (GMM)Robustness checks for alternative estimation methods were performed

Results (1/3): anecdotal evidence
▪ Hypothesis H1 about interchange fees regulation may be rejected
▪ Hypothesis H2 about stimulation of debit card payments market by NPS introduction may be supported
▪ Formal econometric testing is needed

Robustness checks
Robustness check Result
Inclusion of further control variables
Included variables, which may influence transaction volume and checked coefficient sensitivity of variables
Key results are robust to changes
Alternative methods
Checked other possible model estimation methods: Pooled OLS, FE, RE
Key results are robust to changes. Arelano-Bond outperforms the alternatives due to data structure
14
Conclusions
Outcomes: ▪ Interchange fee regulation is inefficient for both card markets (credit card market may be stimulated more)
▪ NPS introduction correlates with higher activity in retail payments market
Further research directions:
▪ More recent or previously omitted data in reports can alter results (although the sample is representative for global payments market)
▪ Other metrics for retail payments market development (e.g., transactions value)
▪ Cause-and-effect analysis of government intervention may be helpful
15
Practical implications
For policy makers:
▪ Understand the correlation between interference into retail payments market and its development
▪ Anticipate potential effects in the markets, where there was no/partial interference
▪ Use the estimate to improve the policies of cashless economy stimulation (especially, the efficiency of tariff stimulation)
For Banking & Financial services
▪ Estimate the potential consequences for consumer behavior after government interference
