This paper uses the adoption and invention of the spinning jenny as a test case to understand why the industrial revolution occurred in Britain in the eighteenth century rather than in France or India.  It is shown that wages were much higher relative to capital prices in Britain than in other...

The commercial value of basic knowledge depends on the arrival of follow-up developments mostly from outside the boundaries of the inventing firm. Private returns would depend on the extent the inventing firm internalizes these follow-up developments. Such internalization is less likely to occur...

It is shown that spillovers can enhance private returns to innovation if they feed back into the dynamic research of the original inventor (Internalized spillovers), but will always reduce private returns, if the original inventor does not benefit from the advancements other inventors build into...

The current paper demonstrates a dochotomy of the growth response to changes in the barter terms of trade (TOT), employing as case studies the following two African countries: Botswana and Nigeria.  Using distributed-lag analysis, the paper finds that the effect of TOT on output is positive and...

The spatial distribution of oil is determined by natural geography alone. However, we show that the distribution of oil exploration is affected by the quality of countries’ institutions. A global data set on the precise location of oil wells and national borders allows for a regression...

Social instability is a concept that economists rarely analyse, and yet it can lurk behind much economic policy-making.  China’s leadership has often publicly expressed its concerns to avoid ‘social instability’.  It is viewed as a threat both to the political order and to...

This paper uses the pooled mean group estimator and an extended annual dataset to examine the effectiveness of aid on growth. The results indicate a significant long-run impact of aid on growth, but conditioning aid on `good` policy reduces the long-run growth rate.

This paper surveys the experience of economic growth in the 20th century with a focus on technological change at the frontier together with issues related to success and failure in catch-up growth.  A detailed account of growth performance based on historical national accounts data is given and...

We develop a framework in which: (i) a firm can have a new product tested publicly before launch; and (ii) tests vary in toughness, holding expertise fixed.  Price flexibility boosts the strong positive impact on consumer beliefs of passing a tough test and mitigates the strong negative impact...

We show that introducing an external capital market with information asymmetry into a product market model reduces opportunistic substitution of sub-standard goods and encourages producers to concentrate on long-run reputation building.  We test this result with a laboratory experiment.  We...
