This paper studies the origins and consequences of international technology gaps. I develop an endogenous growth model where R&D efficiency varies across countries and productivity differences emerge from firm-level technology investments. The theory characterizes how innovation and learning...

We construct a new database which covers production and trade in 136 primary commodities and 24 manufacturing and service sectors for 145 countries. Using this new more granular data, we estimate spillover effects from plausible trade fragmentation scenarios in a new multi-country, multi-sector,...

Economists generally agree that free trade leads to economic growth. This proposition is supported both by theoretical models and empirical data. Further, while the empirical evidence is more limited on this question, the general consensus among economists holds that trade restrictions are...

More than 170 years ago, Frédéric Bastiat noted in his masterly work Economic Sophisms that the “opposition to free trade rests upon errors, or, if you prefer, upon half-truths.”1 Ever since Adam Smith successfully replaced mercantilist orthodoxy with free trade doctrine in his celebrated...

This study explores the impact of oil sector on global competitiveness of the GCC states in a panel data framework for the period from 2006 to 2014. The focus is placed on how the non-traditional factors; oil rents, fuel exports as percentage of merchandise exports, oil prices, and mining sector...

The paper shows that the relationship between GDP per capita and levels of specialization can be predicted differently depending on whether the intensive or the extensive margin is considered. It shows that at the extensive margin countries continuously diversify their exports and that...

According to recent UN projections more than 50 percent of the growth in world population over the next half century will be due to population growth in Africa. Given this, any policy that influences African demography will have a significant impact on the world distribution of income. In this...

This work shows the asymmetric effect of the reduction in transportation costs across different sectors in the process of the Great Divergence. Specifically, the analysis indicates that reductions in transportation costs of industrial goods enhance convergence of the growth rates of trading...

Most of the expansion of global trade during the last three decades has been of the North-South kind – between capital-abundant developed and labour-abundant developing countries. Based on this observation, I argue that the recent growth of world trade is best understood from a...

The weak global GDP growth since the financial crisis in 2007-2009 has coincided with unusually weak growth in global trade. Organisations that monitor international macro-economic development have identified growing protectionism – not least the increase in non-tariff barriers to trade, such...
