In brane inflationary scenarios, the cosmological perturbations are supposed to originate from the vacuum fluctuations of the inflaton field corresponding to the position of the brane. We show that a significant, and possibly dominant, contribution to the curvature perturbation is generated at the end of inflation through the vacuum fluctuations of fields, other than the inflaton, which are lig...

Using subjective well-being data for more than 91,000 individuals in 30 OECD countries, 1990-2008, we study how people’s implicit aversion towards inflation varies with income and other socio-economic characteristics. While inflation aversion decreases with income, it increases with the education level. Contrary to previous findings using statedpreference methods, these relationships apply not ...

Reasoning about how much content to generate when space is limited presents an increasingly important challenge for generation systems, as the diversity of potential delivery channels continues to grow. The problem is multi-facetted: the generated text must fit into the allocated space, the space available must be well utilised, and the resulting text must convey its intended message, and be co...

Using quantitative survey data from the Swedish Consumer Tendency Survey as well as a unique data set on media reports about inflation, we analyze the formation process of inflation perceptions and expectations as well as interrelations between the variables. Throughout the analysis, the role of media reports about inflation is emphasized and results for the low inflation period January 1998 to...

Central banks’ international reserve holdings have increased significantly in the recent past. This paper assesses the consequences for monetary policy both on theoretical and empirical grounds. According to the quantity theory of money, the accumulation of reserves might result in inflationary pressures if the resulting monetary expansion is not fully sterilized and exceeds the growth of money...

European Monetary Union will come into existence in 1999. This raises questions related to the monetary policy targets that will be adopted by the European Central Bank (ECB). For both likely candidates, targeting a money aggregate or an inflation target, the existence of a stable money demand function at a European level is important. In this paper estimates of such a European money demand for...
