Multinational Corporations, Transfer Prices, and Taxes: Evidence from the U.S. Petroleum Industry
Economic research on transfer-pricing behavior by multinational corporadons has emphasized theoretical modeling and institutional description. This paper presents the fiit systematic empirical analysis of transfer prices, using data from the petroleum industry. On the basis of oil imported into the United States over the period 1973 - 1984, we test two propositions: i) Are prices set by integrated companies for their internal transfers different from those prevailing in arm 's-length (i.e., inter-company) trade, when other variables, such as oil quality, are controlled for? ii) Do average effective corporate income tar rates explain observed patterns of transfer pricing? Regression analysis leads to the following conclusions: i) Transfer and arm's-length prices differ significantly for oil origznating in some countries but not all. When multiplied by the relevant import volumes, these differences are relatively smalL The revenue transferred through deviations from arm's-length prices represents two percent or less of the value of the crude oil imported by multinational companies each year. ii) The observed differences between arm's-length and transfer prices are not easily explained by average effective tax rates in exporting countries. Our results provide little support for the claim that multinational petroleum companies set their transfer prices to evade taxes. We offer several hypotheses to explain our findings.

Electromagnetic Polarisability of the Nucleon in Chiral Perturbation Theory
We compute the polarisability of the nucleon to leading order in chiral
perturbation theory. The contributions from kaons and baryon resonances as
intermediate states are included in addition to the contribution from pions and
nucleons that had been previously computed. The isoscalar operators are
dominated by the infrared behaviour of pion loops giving rise to a
coefficient. In contrast, the isovector operators are dominated by loops
involving kaons, giving a coefficient, and further demonstrates that
the strange quark is an important component of the nucleon. In addition, the
inclusion of the decuplet of baryon resonances as intermediate states
substantially modifies the result found from the octet baryons alone for the
isoscalar polarisability.Comment: 11 pages (uses harvmac, figures available upon request) , UCSD/PTH

Virtual Compton Scattering and Generalized Polarizabilities of the Proton
Threshold photon electroproduction off the proton allows one to measure new
electromagnetic observables which generalise the usual polarisabilities. There
are -- a priori -- ten "generalised polarisabilities", functions of the virtual
photon mass. The purpose of this paper is to lay down the appropriate formalism
to extract these quantities from the photon electroproduction cross sections.
We also give a first estimate of the generalised polarisabilities in the non
relativistic quark model.Comment: 45 page postscript file including 2 figures (length just over 1Mb);

Higher Order Polarizabilities of the Proton
Compton scattering results are used to probe proton structure via measurement
of higher order polarizabilities. Values for
determined via
dispersion relations are compared to predictions based upon chiral symmetry and
from the constituent quark model. Extensions to spin-polarizabilities are also
discussed.Comment: 18 pages, revised version with one reference adde
Electromagnetic Polarizabilities and Charge Radii of the Nucleons in the Diquark-model
The diquark model is used to calculate the electromagnetic polarizabilities
and charge radii of the nucleons for three different potentials. Making the
scalar diquark lower in mass introduces a mixing angle between the
and states ,which allows an
improvement in value of all 6 properties. Generalizing the Gamov-Teller matrix
and the magnetic moment operator to the diquark model gives constraints on this
mixing. We obtain for the Richardson potential
Additional pion cloud contributions could
improve on all six results.Comment: 15 Pages, Latex, Figs on request, to be published Phys.Lett.B. Minor

Electric Polarizability of the Nucleon in the Nambu--Jona-Lasinio Model
The electric polarizability of the nucleon is calculated in the soliton
approach to the Nambu--Jona-Lasinio model. We analyze the leading-
contributions, as well as the effects of rotational corrections and
- mass splitting. Our model prediction is substantially reduced
compared to other soliton calculations, and is closer to the experimental
value.Comment: 16 pages, RevTeX, 3 figures (included, PS, uuencoded), RUB-TPII-55/93
