Background
I Much emphasis in tax and development debates on thepotential losses of tax revenues that is due to capital �ight
I Capital �ight (sudden out�ow of cash and securities) canpartly be illicit / at least in the gray area
I Such activities can be undertaken by both individuals (notreporting capital income they hold o�shore) or �rms (bytransfer pricing)
I How severe are the revenue losses due to such activities?
I Our recent UNU-WIDER study (Johannesen and Pirttilä,2016) o�ers a critical review of current estimates

Estimates of hidden wealth by individuals
I Zucman (2013, 2015) estimates the extent of �nancial wealthheld by private individuals o�shore
I The method relies on anomalies in countries' portfoliosecurities data (assets and liabilities positions of countries)
I worldwide total liabilities exceed total assetsI because assets held in tax havens are not reported
I there is also a systematic pattern that tax havens feature thelargest discrepancies

The sources-and-uses and hot-money methods
I Uses countries' balance of payments dataI Sources: (net) increases in foreign debt and (net) increases inforeign direct investment
I Uses: the de�cit on the current account and increases in thecountry's foreign reserves
I If sources exceed uses, it is thought that this must be due totransfers of capital to foreign countries by private individuals
I This includes errors and omissions + some other �ows (suchas deposits by foreign banks + short-term capital �ows)
I Therefore, recent hot money estimates concentrate only onerrors and omissions
9 / 24
Results from these methods
I Zucman estimates that 8% of �nancial wealth is hidden in taxhavens
I Using assumptions on rates of return and e�ective capitalincome tax rates, the stock can be changed into a �ow ofrevenue losses
I worldwide summing up to around 200 billion USD annually
I Sources and usesI United Nations Development Programme (2011): US$20billion from the least developed countries
I Henry (2012):US$150�200 billion from all developing countries
I Hot money narrowI Global Financial Integrity (2015): US$200 billion fromdeveloping countries

Corporate tax spillovers
I Using country-level panel data, the IMF (Crivelli, de Mooij,and Keen, 2015) examines responses of
I countries' tax bases on their neighbours' tax ratesI countries' tax rates on their neighbours' tax rates
I The former, the base spillovers, more important in relativeterms for countries outside of the OECD
I Their tax revenue losses amount to approximately 1.3 per centof their GDP
13 / 24
Gross excluding reversals
I Estimates by Global Financial Integrity (2015) have attractedmuch attention
I Their methodI hot-money-narrow + trade misinvoicing = total illicit �owsI 200 billion USD + 800 billion USD = 1 trillion USD
I The trade misinvoicing part responsible for the great majorityof �ows
I whether this part is right is decisive
14 / 24
Trade misinvoicing channel
I If rich country imports exceed exports from developing country+ trade costs (10%) = seen as evidence of exportunderinvoicing = illicit out�ow
I Similarly overinvoiced imports lead to unreported out�ows
I Some problemsI estimates can be sensitive to what is assumed of trade costsI all false claims are assumed to be made by developing countriesI estimates very fragile (�uctuate a lot from year to year)I products di�erently categorized in origin and destinationcountries (that is why product-level analysis often misleading)
15 / 24
Trade misinvoicing channel II
I Perhaps most puzzling is that if one estimates also illicitin�ows using the same method (but a mirror image), theyexceed illicit out�ows. So on average, developing countriesbene�t from these �ows
I Bottom line: it is hard to use their numbers to come up withconvincing estimates (see also Nitsch 2016)
I Even if numbers were correct, one needs to remember that thegreatest out�ows are from large middle-income countries,meaning that public �nance issues in poorest countries wouldnot be solved if these �ows were curtailed

Utilizing international enterprise data sets
I This research strategy utilizes �rm-level panels where parentsand their subsidiaries are linked to study transfer mispricing
I �rms can use within-company-chain pricing to shift pro�tsacross borders
I The pro�t shown in an a�liate is explained by the tax variables(e.g. the tax di�erence between the destination and the origin)
I The method has been used outside of developed countries onlyvery recently:
I OECD (2015): estimated annual global loss of governmentrevenue from base erosion and pro�t shifting of aroundUS$100�240 billion
I Johannesen, Tørsløv, and Wier (2016): develop methods thatare less demanding in terms of data requirements and applythem to a global sample of multinational �rms. Reportedpro�ts are roughly twice as sensitive to tax incentives indeveloping countries as in developed countries.

Some new approaches
I Using customs data to impute transfer pricingI Cristea and Nguyen (2016): Danish �rms + foreign taxvariation
I Event studiesI Johannesen and Larsen (2016): study the adoption of new�nancial reporting standards by the European Commission forthe value of oil, gas, and mining �rms (value dropped up to10%)
I LeaksI Galizia and Galizia (2016): leaked data by InternationalConsortium of Investigative Journalists used to study theresponses to European savings directive

What do the numbers mean for Africa?
I Zucman (2015) calculates that Africa loses tax revenuesamounting to 14 billion USD due to capital held o�shore byindividuals
I Applying the estimates of Crivelli, de Mooij, and Keen (2015)implies that the revenue loss from income-shifting by MNEs isapproximately 20 billion USD
I At the same time, ODA to Africa (50 billion USD) exceeds therevenue loss due to illegal capital �ight in Africa
I the revenue loss is around 10% of their tax revenuesI also smaller than FDI or remittances
I To sum up: illicit capital �ight is a serious problem butunlikely to solve African revenue issues. Domestic sourcesmust continue to be responsible for the bulk of tax collection
21 / 24
Conclusion
I It is true that developing countries are more vulnerable tocapital �ight (also because of the greater relative importanceof the CIT)
I Research on illicit �nancial �ows bene�ts from shiftingattention to more credible micro-data based estimates
I also studies evaluating the e�ectiveness of policies designed tocombat these �ows
I using peer review to screen the results before publishing
I Investing in technical assistance to help tax agencies to raiserevenues from both domestic actors and multinationals holdsconsiderable promise
I Supporting international tax units in the revenue authorities indeveloping countries to bene�t more from international taxinformation exchange would be one example of such initiatives.
