SUMMARY One of the major challenges of empirical tax research is the identification and calculation of appropriate tax data. While there is consensus that average marginal tax rates are most suitable for studying the effects of tax policy on economic growth, because of data limitations the calculation of marginal tax rates has been limited to the USA and the UK. This paper provides calculations of average marginal tax rates for the four Scandinavian countries using the methodologies of Seater (1982, 1985) and Barro and Sahasakul (1983, 1986). Then, by pooling the newly calculated tax rates for the Scandinavian countries with the data for the USA and the UK, we investigate the effects of tax policy shocks on the per capita GDP growth rate. Our results suggest that an increase in average marginal tax rates has a negative impact on economic growth. Employing additive mixed panel models with penalized splines as estimation approach, we show that changes in tax rates have nonlinear effects. Increasing average marginal tax rates turn out to be the most distorting at relatively moderate tax rates. Copyright © 2013 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]

Using industry data for the United States and the United Kingdom, we provide new evidence on the impact of information and communications technology (ICT) capital on real output growth. The traditional industry panel data analysis fails to find a positive contribution. We argue that this is due to heterogeneity across industries, particularly in the time dimension. Pooling the data for the two countries and using a dynamic panel data estimation method yield a positive and significant effect of ICT on output growth. Individual country estimates suggest a strong impact in the United States, while results are less conclusive in the United Kingdom. [ABSTRACT FROM AUTHOR]

We analyze the impact of volatility per se on real exports for a small open economy concentrating on Irish trade with the United Kingdom and the United States. An important element is that we take account of the time lag between the trade decision and the actual trade or payments taking place by using a flexible lag approach. Rather than adopting a single measure of risk, we adopt a spectrum of risk measures and detail varied size characteristics and statistical properties. We find that the ambiguous results found to date may be due to not taking account of the timing effect, which varies substantially depending on which volatility measure is used.

This article presents the Hudson report on economic condition of Great Britain. According to the standard economic indices, Britain's growth rate averaged a mere 2-8 per cent, over the last eighteen years, comparable with that of the U.S., but well below that of France, Italy, Germany and Japan. If the problem is not solved, say the authors, Britain is headed for "a social and political upheaval". There is no shortage of explanations for Britain's relative decline, though it is hard to tell from the writing which is cause and which is effect.
