In this paper we study the coevolutionary dynamics of knowledge creation, diffusion and the formation of R&D collaboration networks. Differently to previous works, knowledge is not treated as an abstract scalar variable but represented by a portfolio of ideas that changes over time through innovations and knowledge spillovers between collaborating firms. The collaborations…

External circumstances and internal bodily states often change and require organisms to flexibly adapt valuation processes to select the optimal action in a given context. Here, we investigate the neurobiology of context-dependent valuation in 22 human subjects using functional magnetic resonance imaging. Subjects made binary choices between visual stimuli with three attributes (…

Based on a massive data collection effort since the St. Petersburg G20 summit last September, in which a further 2,001 trade-related state initiatives have been documented, this report demonstrates that the resort to protectionism has been substantially higher than previously thought.

This study tests the two assumptions underlying popularly held notions that
maternal employment negatively affects children because it reduces time spent with parents: (1) that maternal employment reduces children's time with parents, and (2) that time with parents affects child outcomes. We analyze children's time-diary data from the Child Development Supplement of…

This paper shows that debt crises do not always have a fiscal nature and suggests that fiscal retrenchment may not be the optimal response to a crisis that did not originate from irresponsible fiscal policies. The paper starts by discussing the origin of debt crises and the unexplained part of public debt and for avoiding debt explosions linked to financial crises or poor debt…

Understanding the institutional features that can improve learning outcomes and reduce inequality is a top priority for international and development organizations around the world. Economists appear to have a good case for support to non-governmental alternatives as suppliers of schooling. However, unlike other policy domains, freer international trade or privatization, economists…

We introduce matched-filter fMRI, which improves BOLD (blood oxygen level dependent) sensitivity by variable-density image acquisition tailored to subsequent image smoothing. Image smoothing is an established post-processing technique used in the vast majority of fMRI studies. Here we show that the signal-to-noise ratio of the resulting smoothed data can be substantially increased by…

It is well established that private information is critical to our understanding of asset prices. In this paper we argue that it also affects international capital flows and use a simple two-country DSGE model to illustrate its impact. We show that private information (i) increases the volatility of both net and gross capital flows, (ii) leads to a high correlation between capital…

Since time immemorial, parents have struggled with the question of how best to raise their children. This column argues that the choice of parenting style is driven by incentives. Parents weigh the expected costs and benefits of implementing a certain parenting style. The popularity of the authoritarian style is declining because the economic returns to the independence of children…
