Necessary and sufficient conditions are derived for optimal saving in a stochastic neo-classical one-good world with discrete time. The usual technique of dynamic programming is replaced by classical variational and concavity arguments, modified to take account of conditions of measurability...

We study substitutions between home and market production over long periods of time. We use the results to get predictions about long-run trends in aggregate market hours of work and about employment shifts across economic sectors, driven by uneven TFP growth in market and home production. The...

Many cultural products have the same nonrival nature as scientific knowledge. They therefore face identical difficulties in creation and dissemination. One traditional view says market failure is endemic: societies tolerate monopolistic inefficiency in intellectual property (IP) protection to...

In Part A of the present study, subtitled 'The Consumption Function as Solution of a Boundary Value Problem' Discussion Paper No. TE/96/297, STICERD, London School of Economics, we formulated a Brownian model of accumulation and derived sufficient conditions for optimality of a plan generated by...

Do other peoples’ incomes reduce the happiness which people in advanced countries experience from any given income? And does this help to explain why in the U.S., Germany and some other advanced countries, happiness has been constant for many decades? The answer to both questions is ‘Yes’....

How big a boost to long run growth can countries expect from the ICT revolution? I use the results of growth accounting and the insights from a two-sector growth model to answer this question. The use of a two-sector rather than a one-sector model is required because of the very rapid rate at...

We study a multi-sector model of growth with differences in TFP growth rates across sectors and derive sufficient conditions for the coexistence of structural change, characterized by sectoral labor reallocation, and balanced aggregate growth. The conditions are weak restrictions on the utility...
