Politically connected firms in Tunisia
Bob Rijkers, Leila Baghdadi, Hassen Arouri
Introduction
Why Study State-Business Relationships?
• Arab Spring often blamed on inequality, corruption, and economic stagnation– Stipulated Common Cause: Abuse of power by ruling elite
• Examining state-business relationships can– Unveil mechanisms by which rent seeking arises – Help identify reform priorities
• Case-Study: Tunisia
How Do Dictators Get Rich? Mechanisms and Hypotheses
– Regulatory Capture H0: Entry regulation was not (ab)used to serve the
president’s (family’s) business interests
– Privatization H0: Privatization served the public interest
– Tax Evasion H0: Connected entrepreneurs are not more likely to evade taxes
Why Tunisia?• Celebrated development model & (Pre-)Arab Spring “Success” Story
– Highly interventionist policies & extensive interaction between Ben Ali and investors– Stable growth – but also persistent unemployment– The Birthplace of the Arab Spring
• Data Availability– Information on Ben Ali owned firms confiscated in the aftermath of the revolts– Other data:
• firm census (1996-2010)• tax data (2000-2010)• data on investment regulations (1994-2010)• data on privatizations (1998-2010)• customs transactions records (by firm-product and country – 2000-2009)
– Complemented with ‘mirror’ statistics
Why Tunisia?
Outline • Introduction
• Data & Descriptive Statistics
• Regulatory Capture
• Privatization
• Tax Evasion
• Conclusion
Outline
Main Findings• Ben Ali’s business interests were important in aggregate
– 662 connected firms (0.2% of all firms) account for 5% of private output and 16% of profits
• The Ben Ali clan engaged in– (i) regulatory capture– (ii) perverted privatizations– (iii) tax evasion
…. and these were resulted in fiscal losses, inequity and inefficiency – Ben Ali presence is associated with reduced competition– 1.2 billion in foregone import tariffs alone
• State-Business relationships continue to be problematic– The Revolution reduced privileges enjoyed by Ben Ali firms– But evidence that corruption “democratized”: Tax evasion has increased– Laws that Ben Ali put in place have not been changed
• Connected firms are more likely to evade import tariffs

There is a premium on being connected Which is especially big for large firms in highly regulated sectors
Taking Stock
• Ben Ali firms are important from a macroeconomic perspective
• Being connected is especially valuable for large firms in sectors subject to severe entry restrictions
• Causality is difficult to establish, but the results are consistent with regulatory capture
Taking Stock
Privatization
Perverted Privatizations?• 8 out of 84 privatizations since 1998 ended up in the
hands of the Ben Ali family– 2 of them coincided with family events
• ENNAKL was privatized to Sakhr el-Matri (husband of Nesrine Ben Ali – following their marriage)
• STAFIM-PEUGEOT was privatized to Mehdi Ben Gaied (fiancé of Halima Ben Ali -following their engagement)
• Were prices appropriate?– Example: ENNAKL:
• Sold for 17 million TND in 2006 (annual profits 3 million TND)• Cumulative profits 2007 & 2008: 39 million TND
Privatization to the family was associated with improved performance
Tax Evasion
Taking Stock
• Strategy: Identify discrepancies between different administrative databases– Do firms that report hiring workers to the social security
administration and/or exporting or importing submit tax declarations?
– Are the sales reported to the tax authorities consistent with the amount they spent on wages, and their reported imports and exports?

What Happened After the Revolution?
Conclusion
Conclusion
• The Ben Ali clan enriched itself both by (ab)using the law and by breaking it, resulting in:– Fiscal Losses
• Connected firms are estimated to have evaded at least 1.2 billion USD worth of import tariffs
– Inequity• BA firms accounted for a disproportionate share of profits & enjoyed
regulatory privileges
– Inefficiency• Evasion endows perpetrators with a cost advantage not based on
performance• BA presence was associated with less competition in highly regulated
sectors
Conclusion
Conclusion• The Arab Spring reduced regulatory privileges enjoyed by the Ben
Ali clan – Competition improved in highly regulated sectors in which the clan had
extensive interests– Tariff evasion diminished in product lines previously dominated by Ben Ali
• Yet state-business relationships continue to be problematic – arguably more now than ever before– Tax evasion is on the rise– Laws put in place by Ben Ali that facilitate capture have remained in place
What happened after the Arab Spring?
Extra Slides
Data• Identification of Ben Ali’s Business Interests
– 662 firms owned by Ben Ali or his family confiscated in the aftermath of the Jasmin Revolution
• Administrative data on firm performance– Firm census data: 1996-2010: all private firms– Tax data: 2000-2010: all private firms– Customs transactions data by firm-product-origin: 2000-2009:
all firms• And “mirror” data from WITS
– Privatizations: 1998-2010
• Data on investment regulations (coded manually)
Data
Provisions in the Investment Code
• Tunisian Investment Code (Law 93-120)– Governs investments in all sectors of the economy except mining,
finance, and domestic commerce.– Amended by 25 presidential decrees provides variation over time
• Decrees were signed by Ben Ali and ratified by the cabinet
• Two Types of Restrictions on Entry: – Authorization Requirements – e.g. need government approval to be
able to run a firm.• E.g. in fishing, tourism (travel agencies), air transport, maritime transport,
road transport, telecommunication, education, the film industry, real estate, marketing, health related industries
– FDI Restrictions – need permission from the Commission superieure d’Investissement – notoriously difficult
• e.g. in transport, communications, tourism, education, cultural production, entertainment, construction, real estate

But prices drop when firms become connected
How Big Were the Losses Due to Evasion?
• Losses due to underreporting alone: 1.2 Billion USD (between 2002-2009) MORE than other firms
• Key assumption– Unit price difference between Ben Ali and other private firms
are due to evasion
• Conservative: – Tariff data often missing & Don’t always have a private sector
reference price s– Do not account for other types of fraud
• E.g. abuse of duty suspension regimes, under-reporting of quantities, smuggling etc.
