Essentials of Jamaican taxation

This fourth edition of Essentials of Jamaican Taxation as with earlier editions covers the material for an undergraduate course in Jamaican taxation and deals with the theory of taxation and its application through the main provisions of the Income Tax Act, the various Acts governing payroll taxes, the General Consumption Tax Act and the Contractors Levy Act. This edition covers changes which took place after 2007 including the main provisions in the 2012 budget. The text is designed to give mainly students of accounting a working knowledge of taxation as it is administered in Jamaica so they are equipped to perform computations of tax payable by businesses/employers, employees, self-employed, and persons with income from sources other than employment. Most of the text should be understood quite readily by readers other than students who wish to be informed on taxation matters.

Why does tax have to be so taxing? The Court revisits the Franked Investment Income litigation

Examines the European Court of Justice ruling in Test Claimants in the FII Group Litigation v Inland Revenue Commissioners (C-35/11) on whether the differential tax treatment of domestic and foreign-sourced dividends in the UK was compatible with the freedom of establishment and free movement of capital principles. Outlines its guidance on how to assess this compatibility. Considers the ruling's implications for the UK tax system, the relationship between tax sovereignty and the internal market and the third-country dimension of the free movement of capital principle.

The determinants of tax haven FDI

This paper examines the determinants of a multinational enterprise’s (MNEs) decision to set up tax haven subsidiaries. We adapt the Firm-specific advantage–Country-specific advantage (FSA–CSA) framework and construct a number of empirically testable hypotheses. The analysis is based on a database covering 14,209 MNEs in twelve OECD countries. We find that the variety of capitalism of a MNEs home location and the level of technological intensity has a strong impact on this decision. We also find that the home country corporate tax rate has a minimal impact. This suggests that corporate tax liberalisation is unlikely to deter MNEs from undertaking this activity.

Flat-top supercontinuum and tunable femtosecond fiber laser sources at 1.9-2.5 μm

We report the high-energy flat-top supercontinuum covering the mid-infrared wavelength range of 1.9-2.5 μm as well as electronically tunable femtosecond pulses between 1.98-2.22 μm directly from the thulium-doped fiber laser amplifier. Comparison of experimental results with numerical simulations confirms that both sources employ the same nonlinear optical mechanism - Raman soliton frequency shift occurring inside the Tm-fiber amplifier. To illustrate that, we investigate two versions of the compact diode-pumped SESAM mode-locked femtosecond thulium-doped all-silica-fiber-based laser system providing either broadband supercontinuum or tunable Raman soliton output, depending on the parameters of the system. The first system operates in the Raman soliton regime providing femtosecond pulses tunable between 1.98-2.22 μm. Wide and continuous spectral tunability over 240 nm was realized by changing only the amplifier pump diode current. The second system generates high-energy supercontinuum with the superior spectral flatness of better than 1 dB covering the wavelength range of 1.9-2.5 μm, with the total output energy as high as 0.284 μJ, the average power of 2.1 W at 7.5 MHz repetition rate. We simulate the amplifier operation in the Raman soliton self-frequency shift regime and discuss the role of induced Raman scattering in supercontinuum formation inside the fiber amplifier. We compare this system with a more traditional 1.85-2.53 μm supercontinuum source in the external highly-nonlinear commercial chalcogenide fiber using the Raman soliton MOPA as an excitation source. The reported systems1 can be readily applied to a number of industrial applications in the mid-IR, including sensing, stand-off detection, medical surgery and fine material processing.
