Incentives and Information Exchange in International Taxation

The exchange of taxpayer-specific information between national tax authorities has recently emerged as a key and controversial topic in international tax policy discussions, most notably with the OECD's harmful tax practices project and the EU's savings tax initiative. This paper analyzes the effects of information exchange and withholding taxes, recognizing that countries which agree to exchange information do not forfeit the ability to levy withholding taxes, and also focusing in particular on the effects of innovative revenue-sharing arrangements. Amongst the findings are that: (i) the transfer of withholding tax receipts to the residence country, as planned in the European Union, has no effect on equilibrium tax rates, but acts purely as a lump-sum transfer; (ii) in contrast, allocating some of the revenue from information exchange to the source country—counter to usual practice (though no less so than the EU agreement)—would have adverse strategic effects on total revenue; (iii) nevertheless, any withholding tax regime is Pareto dominated by information exchange combined with appropriate revenue sharing; and, in particular, (iv) sharing of the additional revenues raised from information provided, while efficiency-reducing, could be in the interests of large countries as a means of persuading small countries to provide that information voluntarily.

Tax revenue and (or?) trade liberalization

With the public finances of many developing and emerging market countries still heavily dependent on trade tax revenues, further trade liberalization may be hindered unless they are able to develop alternative sources of revenue. Against a background of, and to inform, heightened theoretical controversy as to the appropriate balance between trade and other taxes (not least the VAT), this paper uses panel data for 117 countries over 32 years—cleaned for a variety of problems in standard data sources—to address a central question of fact: Have countries recovered from domestic taxes the revenues they have lost from past episodes of trade liberalization? For high income countries, the answer is clearly ‘yes.’ For middle income countries, there are robust signs of strong replacement both concurrently with the revenue loss and—essentially dollar-for-dollar—in the long run. Signs of significant recovery by low income countries are flimsier, however, and their experiences appear to have varied widely. The picture that emerges for low income countries is thus that replacement has been (and become) higher than previous studies have suggested, but sufficiently incomplete in many cases to give cause for concern.     

Indirect Taxes on International Aviation*

There has recently been much discussion of the possible use of internationally coordinated indirect taxes, or equivalent charges, on international aviation, whether as a source of finance for development or as part of a response to heightened concerns with climate change. This paper considers the strengths and weaknesses of the leading candidate instruments of this kind. It argues that, on both policy and administration grounds, the case for increasing indirect taxes on international aviation is strong: the indirect tax burden on international aviation is very low, yet aviation contributes significantly to border-crossing environmental damage, is just as proper an object of taxation as any other commodity, and incipient tax competition is likely to result in these taxes being set at inefficiently low levels. But the form(s) in which such taxes are levied matters: a tax on aviation fuel would address the key border-crossing externalities most directly; a tax on final ticket values would have greater revenue potential, and perhaps some distributional advantage; departure/arrival taxes face the least legal obstacles, but are much blunter instruments. Optimal policy, it is shown, typically requires deploying both a fuel tax and a ticket tax, and the paper explores, both in principle and by simulation, the key considerations and trade-offs involved in designing a suitable indirect tax regime for international aviation.     

SUCCESSIVE MEASUREMENT EXPERIMENTS

Abstract. We consider methods for the analysis of successive measurements, with emphasis on practical usefulness. It is described how the methods can be applied by using common techniques like regression analysis and analysis of variance.     

Zero expenditures and the estimation of engel curves

Over the brief interview periods typical of budget surveys (such as the U.K. Family Expenditure Survey) households' recorded expenditures are liable to be misleading indicators of their underlying consumption. Most starkly, a household may not be observed to purchase commodities that it nevertheless consumes. This paper considers the implications of such measurement errors for the estimation of demand systems, and derives a consistent estimator for the special case of linear Engel curves.     

The rise and fall of Spain (1270–1850)1

Two distinctive regimes are distinguished in Spain over half a millennium. The first one (1270s–1590s) corresponds to a high land–labour ratio frontier economy, which is pastoral, trade‐oriented, and led by towns. Wages and food consumption were relatively high. Sustained per capita growth occurred from the end of the Reconquest (1264) to the Black Death (1340s) and resumed from the 1390s only broken by late fifteenth‐century turmoil. A second regime (1600s–1810s) corresponds to a more agricultural and densely populated low‐wage economy which, although it grew at a pace similar to that of 1270–1600, remained at a lower level. Contrary to pre‐industrial western Europe, Spain achieved its highest living standards in the 1340s, not by mid‐fifteenth century. Although its death toll was lower, the plague had a more damaging impact on Spain and, far from releasing non‐existent demographic pressure, destroyed the equilibrium between scarce population and abundant resources. Pre‐1350 per capita income was reached by the late sixteenth century but only exceeded after 1820.     

Uganda's experience with aid

This paper presents Uganda's experience with aid flows overthe period 1970-96. It discusses the compilation of aid dataand also reviews the chronological developments in aid flowsto Uganda. Over this period, the sectoral distribution and typeof aid is largely dictated by the government's economic programmesin place. The period 1962-71 largely reflects government borrowingfor on-lending to agriculture and industry whereas the period1979-85 shows a wider range of sector-specific programmes drivenby the need to reconstruct and rehabilitate the economy. Althoughthe need to reconstruct and rehabilitate the economy continued,support for policy reform began to take up an increasing proportionof aid over the period 1987-96. We also analyse the impact ofaid on some major macroeconomic variables and find that investmentand real exchange rate developments have been largely drivenby official development aid flows. Although we find a similarrelationship between aid and improved policy environment, thefindings show that in the latter part, i.e., 1992-6, the continuedpolicy reform was driven more by ownership of the programmethan by aid. Indeed, in this latter period, the aid/GDP ratiosdeclined. The major lesson drawn from this study is that ownershipof a reform programme is more critical for its success, henceour conclusion that aid should be used for financing ratherthan buying reforms.
