measuring and improving the performance of customs valuation controls an illustration with gabon modern customs administrations aim to both facilitate legal trade and combat fraud to meet this dual objective many customs administrations in developing countries must give risk management a highly prominent role in this context of modernisation this paper first provides stylised facts on the performance of the customs controls carried out at the gabon border then we compare gabon s granular import customs data with international trade statistics based on this comparison we identify undetected fraud and present a methodology to target ex post audits finally we define indicators to monitor the performance of customs valuation controls

an econometric investigation of capital flight this paper seeks to give a comprehensive empirical survey of private capital flight from developing countries first three alternative calcualtions of net private capital outflows are presented for 22 developing countries during 1978 85 it turns out that several of these countries had experienced major capital flight second using an economtric model which combines time series and cross section data a portfolio model is estimated in order to find some of the reasons for capital flight third on quarterly time series capital flight from mexico is determined in a time jseries model this analysis gives further insight into the causes of capital flight the overall result from both studies is that changes in the expected relative rate of return on assets between the foreign and domestic market are a major cause of capital flight

tariff evasion and rules of origin violations under the canada u s free trade agreement using product level data on trade between canada and the u s this paper presents evidence of tariff evasion and violation of the rules of origin occurring under the canada u s free trade agreement cusfta it shows that more imports go unreported at the destination country when tariffs are higher consistent with the tariff evasion hypothesis this result implies that the trade creation effect of a free trade agreement may in fact be due to less underreporting further this paper shows that the larger canadian tariff preference margin for the u s is associated with more goods originating in third countries being transshipped through the u s territory for re export the preference margin is also positively correlated with the value of excess imports from the u s which qualify for preferential treatment both results suggest the presence of persistent violations of cusfta s rules of origin a l aide de donnees au niveau des produits sur les flux de commerce entre le canada et les etats unis on montre qu il y a evitement de tarif et violation des regles d origine dans les operations de l accord de libre echange canada etats unis on montre que davantage d importations ne sont pas declarees au point de destination quand les tarifs sont eleves dans l esprit meme de l hypothese d evitement de tarif ce resultat implique que l effet de creation de commerce d un accord de libre echange peut en fait etre attribuable a moins de sous declaration de plus le texte montre que les plus grandes marges preferentielles des tarifs avec les etats unis sont associees a davantage de biens en provenance de tiers pays et convoyes a travers le territoire americain pour re exportation la marge preferentielle est aussi positivement co reliee avec la valeur des importations excedentaires en provenance des etats unis qui se qualifient pour un traitement preferentiel ces deux ensembles de resultats suggerent la presence persistante de violations des regles d origine de l accord de libre echange canada etats unis

entrepot trade and smuggling in west africa benin togo and nigeria official trade statistics indicate very little intra african trade but this is often because of the prevalence of unrecorded trade particularly smuggling this paper explores smuggling from benin and togo into nigeria nigeria has very high import tariffs and bans on certain products togo and benin have deliberately maintained low import barriers to facilitate an entrepot role vis a vis nigeria and land locked sahelian countries togo competes at a geographic disadvantage relative to benin for access to the nigerian market and compensates with lower transit taxes the volume and composition of cross border trade is analysed using data obtained from benin and togo customs authorities as well as interviews with traders and customs officials in both countries benin and to a lesser extent togo are the origin of a very large volume of transshipment of precisely those products which are heavily protected in nigeria such as used cars cloth and rice it is common knowledge in benin and togo that these imports although declared for domestic consumption or transit to other countries are in fact overwhelmingly intended for nigeria smuggling is a major source of income and employment in benin and togo but provides a fragile and unreliable foundation for economic development

the effect of financial liberalization on capital flight in african economies summary in this paper we assess the effects of financial liberalization on capital flight in african economies a portfolio model in which capital flight is one of the assets is estimated on a sample of nine african countries for 1970 91 the estimation results suggest that financial liberalization induces a reduction in capital flight after augmenting the model with submodels for the banking sector the government sector and the external sector we conduct simulation experiments involving an interest rate deregulation a decrease in reserve requirements and a change in exchange rate policy the simulation results show that capital flight is reduced by all the three financial liberalization measures the effects however are very small considering both the estimation and simulation results we conclude that financial liberalization policies are useful in attempts to reduce capital flight in african economies but per se the policies may not be the panacea

corruption trade costs and gains from tariff liberalization evidence from southern africa this paper exploits quasi experimental variation in tariffs in southern africa to estimate trade elasticities traded quantities respond only weakly to a 30 percent reduction in the average nominal tariff rate trade flow data combined with primary data on firm behavior and bribe payments suggest that corruption is a potential explanation for the observed low elasticities in contexts of pervasive corruption even small bribes can significantly reduce tariffs making tariff liberalization schemes less likely to affect the extensive and the intensive margins of firms import behavior the tariff liberalization scheme is however still associated with improved incentives to accurately report quantities of imported goods and with a significant reduction in bribe transfers from importers to public officials

capital flight in the presence of domestic borrowing evidence from eastern european economies summary we estimate capital flight from 10 central and eastern european countries for the period 1996 2009 capital flight from the transition economies is mainly an economic phenomenon driven by differences in interest rates and investors perceptions of economic conditions in their countries as well as by the ease with which they are able to obtain funds that can be transferred overseas through domestic loans and capital inflows domestic credit expansion is an important source of financing for capital flight paradoxically financial liberalization has fueled rather than reduced capital flight by reducing its costs and increasing the funds that can be moved abroad

national trade policies and smuggling in africa the case of the gambia and senegal summary much of inter regional trade in africa is unrecorded and consists of smuggling the gambia is almost wholly enclosed within senegal yet official trade statistics show almost no trade between the two countries failing to capture large scale smuggling smuggling reflects pre colonial traditional trading relationships the artificial nature of borders created in the colonial era and the disparities in trade policies between the two countries following independence inducing large cross border price differentials for goods this paper documents the magnitude of trade protection in the two countries the resulting price differences and estimates the volume of smuggling

wto accession and tariff evasion abstract this study documents some unintended consequences of the world trade organization wto membership by providing evidence on displacement of tariff evasion driven by the wto accession process the analysis focuses on the wto customs valuation agreement cva which limits the discretion of customs officials when it comes to assessing the price of imports while prior to the wto accession customs officials are free to use their own judgment or apply minimum or reference prices after their country joined the wto they are mandated to accept the invoice price issued by the exporter if customs officials enjoy discretion with respect to assessing the import price they may assist importers with tariff evasion in exchange for bribes removing such discretion limits their ability to facilitate misrepresentation of import prices using data on 15 countries which joined the wto between 1996 and 2008 we find a positive relationship between underreporting of import prices and the tariff rate which is expected as the incentive to evade increases with the tariff rate importantly this relationship disappears after a country joins the wto this result is consistent with the cva closing one channel for corrupt behavior however we also find that changes to customs valuation procedures induce importers to seek alternative ways of tariff evasion such as underreporting of quantities and product misclassification the overall level of evasion remains unchanged

tariffs enforcement and customs evasion evidence from india we examine the effect of tariff policies on evasion of customs duties in the context of the trade reform in india of the 1990s by exploiting the variation in tariff rates across time and products we identify a robust positive elasticity of evasion with respect to tariffs a second contribution of the paper is to provide some evidence on the impact of enforcement while we cannot identify the direct impact of enforcement on evasion we can establish the extent to which enforcement related factors such as product characteristics that determine the ease of detection of evasion affect the evasion elasticity the results render support to the hypothesis that improvements in enforcement can reduce the responsiveness of evasion to tariffs

china s capital flight pre and post crisis experiences abstract we study china s illicit capital flow and document a change in its pattern specifically we observe that china s capital flight especially the one measured by trade misinvoicing exhibits a weakened response in the post 2007 period to the covered interest disparity which is a theoretical determinant of capital flight further analyses indicate that the post 2007 behavior is influenced by quantitative easing and other factors including exchange rate variability capital control policy and trade frictions our study confirms that china s capital flight pattern and its determinants are affected by the crisis event further both the canonical and additional explanatory variables have different effects on different measures of capital flight these results highlight the challenges of managing china s capital flight which requires information on the period and the type of capital flight that the policy authorities would like to target

are politically connected firms more likely to evade taxes evidence from tunisia are politically connected firms more likely to evade taxes using tax social security and customs records from tunisia in which firms owned by former president ben ali and his family are identified this paper demonstrates that connected firms were more likely to evade taxes ceteris paribus connected firms are 4 6 more likely not to submit a tax declaration in spite of registering workers and or customs transactions and 8 4 more likely to report anomalously low sales when submitting a tax declaration

a note on the measurement of equity duration and convexity the appropriate measure of equity duration and by extension convexity is a controversial matter in 1986 leibowitz presented empirical duration measures that are considerably shorter than those derived from a traditional dividend discount model a class of dividend discount models developed by hurley and johnson is used to try to reconcile the difference the values derived for equity duration are intermediate between the leibowitz and traditional measures these models overcome the standard criticism of dividend discount models by allowing for realistic patterns of future dividend growth corresponding models of equity convexity developed by johnson are used to derive equity convexity

capital flight and political risk abstract this paper provides the first serious attempt to examine the relationship between political risk and capital flight for a large set of developing countries the outcomes of the analysis show that in most cases political risk variables do have a statistically robust relationship to capital flight once domestic and international macroeconomic circumstances are added at least when the robustness test as proposed by sala i martin is applied we conclude that on the basis of the analysis in this paper we have found support for the hypothesis that political risk leads to increased capital flight

differentiated products and evasion of import tariffs emerging literature has demonstrated some unique characteristics of trade in differentiated products this paper contributes to the literature by postulating that differentiated products may be subject to greater tariff evasion due to the difficulties associated with assessing their quality and price using product level data on trade between germany and 10 eastern european countries during 1992 2003 the authors find empirical support for this hypothesis they show that the trade gap defined as the discrepancy between the value of exports reported by germany and the value of imports from germany reported by the importing country is positively related to the level of tariff in 8 out of 10 countries further the authors show that the responsiveness of the trade gap to the tariff level is greater for differentiated products than for homogeneous goods a one percentage point increase in the tariff rate is associated with a 0 6 percent increase in the trade gap in the case of homogeneous products and a 2 1 percent increase in the case of differentiated products finally the data indicate that greater tariff evasion observed for differentiated products tends to take place through misrepresentation of the import prices

tax rates and tax evasion evidence from missing imports in china tax evasion by its very nature is difficult to observe we quantify the effects of tax rates on tax evasion by examining the relationship in china between the tariff schedule and the evasion gap which we define as the difference between hong kong s reported exports to china at the product level and china s reported imports from hong kong our results imply that a one percentage point increase in the tax rate is associated with a 3 percent increase in evasion furthermore the evasion gap is negatively correlated with tax rates on closely related products suggesting that evasion takes place partly through misclassification of imports from higher taxed categories to lower taxed ones in addition to underreporting the value of imports

political connections and tariff evasion evidence from tunisia are politically connected firms more likely to evade taxes this paper presents evidence suggesting firms owned by president ben ali and his family were more prone to evade import tariffs during ben ali s reign evasion gaps defined as the difference between the value of exports to tunisia reported by partner countries and the value of imports reported at tunisian customs were correlated with the import share of connected firms this association was especially strong for goods subject to high tariffs and driven by underreporting of unit prices which diminished after the revolution consistent with these product level patterns unit prices reported by connected firms were lower than those reported by other firms and declined faster with tariffs than those of other firms moreover privatization to the ben ali family was associated with a reduction in reported unit prices whereas privatization per se was not

evasion behaviors of exporters and importers evidence from the u s china trade data discrepancy abstract since the late 1990s reported u s imports from china and hong kong have regularly and increasingly exceeded reported exports of china and hong kong to the united states this discrepancy which is not caused by re exporting through hong kong varies by product categories and in some cases takes the opposite sign in this paper we focus on china s direct exports to the united states using a model that allows for simultaneous misreporting to two authorities we find strong statistical evidence of under reporting exports at the chinese border to avoid paying value added tax vat the value of vat avoided is estimated at 6 5 billion during 2002 2008 and the associated understatements account for approximately two thirds of the discrepancy we also provide evidence of tariff evasion at the u s border in particular for related party transactions and indirect evidence of transfer pricing and evasion of chinese capital controls an estimated 2 billion of u s tariff revenue is lost due to such evasion during 2002 2008 which reduces the apparent size of the statistical discrepancy

estimating border tax evasion in mozambique abstract the relationship between border tax rates and evasion is examined for mozambique using the methodology developed by fisman and wei 2004 we find that high tax rates are associated with high levels of under reporting of import values and that tax rates have a strong and positive effect on tax evasion results also strongly confirm the presence of fraudulent classification of merchandise into lower taxed product categories finally analysis of the revenue implications of lower trade taxes finds that the revenue curve is quite flat but remains upward sloping with respect to the tax rate when only evasion is considered

cheating ourselves the economics of tax evasion no government can announce a tax system and then rely on taxpayers sense of duty to remit what is owed some dutiful people will undoubtedly pay what they owe but many others will not over time the ranks of the dutiful will shrink as they see how they are being taken advantage of by the others thus paying taxes must be made a legal responsibility of citizens with penalties attendant on noncompliance but even in the face of those penalties substantial tax evasion exists and always has the history of taxation is replete with episodes of evasion often notable for their inventiveness during the third century many wealthy romans buried their jewelry or stocks of gold coin to evade the luxury tax and homeowners in eighteenth century england temporarily bricked up their fireplaces to escape notice of the hearth tax collector webber and wildavsky 1986 p 141 this essay reviews what is known about the magnitude nature and determinants of tax evasion with an emphasis on the u s income tax alm 1999 andreoni erard and feinstein 1998 and slemrod and yitzhaki 2002 offer more comprehensive recent reviews of the literature it then places this information into a conceptual and policy context

the economics of the arab spring summary a singular failure of the arab world is the absence of a private sector that is independent competitive and integrated with global markets this paper argues that private sector development is both a political and regional challenge in so far as the private sector generates incomes that are independent of the rent streams controlled by the state it can pose a direct political challenge it is also a regional challenge since fragmented markets deny scale economies to firms and entrench the power of insiders we argue that overcoming regional economic barriers constitutes the single most important collective action problem facing the region since the fall of ottoman empire

public debts and private assets explaining capital flight from sub saharan african countries we investigate the determinants of capital flight from 30 sub saharan african countries including 24 countries classified as severely indebted low income countries for the period 1970 1996 the econometric analysis reveals that external borrowing is positively and significantly related to capital flight suggesting that to a large extent capital flight is debt fueled we estimate that for every dollar of external borrowing in the region roughly 80 cents flowed back as capital flight in the same year capital flight also exhibits a high degree of persistence in the sense that past capital flight is correlated with current and future capital flight the growth rate differential between the african country and its oecd trading partners is negatively related to capital flight we also explore the effects of several other factors inflation fiscal policy indicators the interest rate differential exchange rate appreciation financial development and indicators of the political environment and governance we discuss the implications of the results for debt relief and for policies aimed at preventing capital flight and attracting private capital held abroad

capital flight to germany two alternative measures abstract we use two measures to study two capital flight channels for germany one measure is based on the concept of trade misinvoicing and one on net claims and liabilities in the eurosystem of central banks for both measures we propose refinements to enhance the assessment of capital flight we find that capital flight towards germany via these two channels has been quite sizable in the recent decade and can tally to about 2 of gdp annually regarding their determinants we show that the two capital flight measures are driven by both common and measure specific factors traditional determinants such as covered interest differentials only play a limited role while crisis specific factors such as economic policy uncertainty the ecb collateral policy as well as currency misalignment are driving factors of the investors apparent flight to safety behavior

trade policy trade costs and developing country trade this paper briefly reviews new indices of trade restrictiveness and trade facilitation that have been developed at the world bank the paper also compares the trade impact of different types of trade restrictions applied at the border with the effects of domestic policies that affect trade costs based on a gravity regression framework the analysis suggests that tariffs and non tariff measures continue to be a significant source of trade restrictiveness for low income countries despite preferential access programs this is because the value of trade preferences is quite limited a new measure of the relative preference margin developed in the paper reveals that this is very low for most country pairs most countries with very good duty free access to a market generally have competitors that have the same degree of access the empirical analysis suggests that measures to improve logistics performance and facilitate trade are likely to have the greatest positive effects in expanding developing country trade increasing the trade impacts of lowering remaining border barriers by a factor of two or more

integrity for hire an analysis of a widespread customs reform abstract can governments improve bureaucratic performance by hiring integrity from the private sector in the past 2 decades a number of developing countries have hired private firms to conduct preshipment inspections of imports generating independent data on the value and tariff classification of incoming shipments i find that countries implementing such inspection programs subsequently experience large increases in import duty collections by contrast the growth rate of other tax revenues does not change appreciably additional evidence suggests that declines in falsification of import documentation are behind the import duty improvements the programs also lead to declines in undervaluation and misreporting of goods classifications historically this hired integrity appears to have been cost effective with improvements in import duty collections in the first 5 years of a typical inspection program amounting to 2 6 times the program s costs
