‘Better safe than sorry’: consumer perceptions of and deliberations on nanotechnologies

Although nanotechnologies are considered key technologies that can drive growth‐generating innovations in well‐saturated markets, worldwide investment in nanotechnologies has to date focused largely on technology‐related development programmes and little effort has been expended to research associated risks. As a result, even though prior discourses have sensitized western consumers to potential health‐related dangers, solid knowledge on, for example, the toxicological and eco‐toxicological risks and unintended side effects of nanotechnology are scarce. This paper therefore presents an overview of the current evidence on consumer knowledge and perceptions of nanotechnology and public engagement with it, with a focus on the US, the UK and Germany. Overall, even though survey data suggest that awareness of the term ‘nanotechnology’ has risen slightly, today's consumers are generally ill informed about its nature and its applications in consumer‐related products. Hence, based on our analysis of these data, we argue that early political engagement in the nanotechnology issue – for example, consumer policy options that support consumer interest in the marketing of ‘nanos’– would facilitate objective public discourse.     

The spatial component of R&D networks

We study the role of geography in R&D networks by means of a quantitative, micro-geographic approach. Using a large database that covers international R&D collaborations from 1984 to 2009, we localize each actor precisely in space through its latitude and longitude. This allows us to analyze the R&D network at all geographic scales simultaneously. Our empirical results show that despite the high importance of the city level, transnational R&D collaborations at large distances are much more frequent than expected from similar networks. This provides evidence for the ambiguity of distance in economic collaboration which is also suggested by the existing literature. In addition we test whether the hypothesis of local buzz and global pipelines applies to the observed R&D network by calculating well-defined metrics from network theory.     

How do fiscal and technology shocks affect real exchange rates?: New evidence for the United States

Using vector autoregressions on U.S. time series relative to an aggregate of industrialized countries, this paper provides new evidence on the dynamic effects of government spending and technology shocks on the real exchange rate and the terms of trade. To achieve identification, we derive robust restrictions on the sign of several impulse responses from a two-country general equilibrium model. We find that both the real exchange rate and the terms of trade—whose responses are left unrestricted—depreciate in response to expansionary government spending shocks and appreciate in response to positive technology shocks.
