Governments in emerging markets often behave like a quot;tormented insurer,quot; trying to use non-state-contingent debt instruments to avoid cuts in payments to private agents despite large fluctuations in public revenues. In the data, average public debt-GDP ratios decline as the variability...

We contribute to the debate on the macroeconomic effects of fiscal stimuli by showing that the impact of government expenditure shocks depends crucially on key country characteristics, such as the level of development, exchange rate regime, openness to trade, and public indebtedness. Based on a...

This paper assesses the impacts of the WTO Government Procurement Agreement (GPA) on trade in both goods and services among members using a gravity model applied to a panel dataset covering 20 OECD countries over the period 1996-2008 for trade in goods and 1999-2008 for trade in services. The...

Large population / rapidly growing economies such as China and India have argued that in the upcoming UNFCCC negotiations in Copenhagen, any emission reduction targets they take on should be based on their intensity of emissions (emissions/$GDP) on a target date not the level of emissions. They...

This paper focuses on the causes of increased wage inequality in OECD countries in recent years and its decomposition into the component factors of trade surges in low wage products and technological change that has preoccupied the trade and wages literature. It argues that the length of...

I discuss the tax treatment of transborder capital income, focussing on prevailing arrangements rather than de novo design of optimal tax arrangements. These comprise unilateral reliefs from double taxation under credit or exemption systems, and treaty reliefs (largely following the OECD model...

In the paper we discuss China's participation in both the 2009 Copenhagen negotiations on a post-Kyoto global climate change regime currently under way and out beyond Copenhagen in further negotiations likely to follow. China is now both the largest and most rapidly growing carbon emitter, and...

We discuss emerging proposals for border tax adjustments (BTAs) to accompany commitments to reduce carbon emissions in the EU, the US and other OECD economies. The rationale offered for such border adjustment is that various entities, such as the EU, if making commitments to reduce emissions...

We discuss recent cases of Chinese buyout activity in the OECD (especially in the US and the EU) in resource and manufacturing sectors. While most of the buyout attempts have been unsuccessful, they can serve as a catalyst for a wider discussion on the implications for global arrangements over...

How high can public debt rise without compromising fiscal solvency? We answer this question using a stochastic ability-to-pay model of sovereign default in which risk-neutral investors lend to a government that displays "fiscal fatigue," because its ability to increase primary balances cannot...
