Nearly 75 years ago, John Hicks introduced and formalized the concept of the elasticity of substitution between capital and labour and its relation to derived demand. The resulting formula has proven very useful in understanding the derived demand for productive factors, the distribution of...

Long run economic growth goes along with structural change. Recent work has identified explanatory factors on the demand side (non-homothetic preferences) and on the supply-side, in particular differential productivity growth across sectors and differences in factor proportions and capital...

There is growing interest in multi-sector models that combine aggregate balanced growth, consistent with the well-known Kaldor facts, with systematic changes in the sectoral allocation of resources, consistent with the Kuznets facts. Although variations in the income elasticity of demand across...

Based on recent empirical evidence, this paper includes human capital and knowledge in an integrated assessment model and it assesses the interplay between innovation, human capital, climate change, and education policies. Results indicate that climate policy stimulates a dedicated form of...

We discuss the sustainability of Chinese high growth relative to growth experience elsewhere, and specifically Soviet Russia in the 1950s to the 1960s by asking if the aggregate technology can eventually similarly constrain high growth performance in the Chinese case as argued by Weitzman in a...

We develop a dynamic model of intermediate goods trade in which the pattern and the extent of intermediate goods trade are endogenous. We consider a small open economy whose final good production employs an endogenous array of intermediate goods, from low technology (high cost) to high...

This paper develops an open economy model with heterogeneous final goods producers who simultaneously choose whether to export their goods and whether to use imported intermediates. The model highlights mechanisms whereby import policies affect aggregate productivity, resource allocation, and...

We consider a monopolistic supplier’s optimal choice of wholesale tariffs when downstream firms are privately informed about their retail costs. Under discriminatory pricing, downstream firms that differ in their ex ante distribution of retail costs are offered different tariffs. Under uniform...

This paper investigates how the presence of social capital affects the externality arising from status-seeking preference as a parable for inefficient antagonistic behavior. It is assumed that the stock of social capital is accumulating through joint social interaction between rational...
