We construct optimal growth models where labor resources can be allocated either to production, technology adoption or capital maintenance. We first characterize the balanced growth paths of a benchmark model without maintenance. Then we introduce maintenance activity via the depreciation rate of capital. We characterize the optimal allocation of labor across the three activities. Although maintenance deepens the technological gap by diverting labor resources from adoption, we show that it generally increases the long run output level. Moreover, we find that equilibrium maintenance and adoption efforts respond in opposite directions to policy or technology shocks. Finally, we find that the long-term output response to policy shocks is slightly higher in the presence of maintenance. Adapted from the source document.

This article studies the services exchanged in a particular Spanish time bank. Using data from users and transactions, we analyse the users' profile as well as the determinants of providing and receiving different services. Our results show that the representative user is a Spanish female, not married, middle aged, highly educated and unemployed. We also find differences in the personal characteristics driving the supply and demand of services. ; Financial support from the Spanish Government under project ECO2011-29751 by the first author, under project ECO2010-17943 by the second author and under project ECO2012-32854 by the third author is gratefully acknowledged.
