Recent empirical findings attribute a central role to the degree of economic openness for determining the size of the fiscal multiplier. However, traditional macroeconomic models have difficulties in accounting for this evidence. It is the purpose of this paper to provide a theoretical framework...

This essay examines the implications of openness to trade, capital mobility, and exchange rate exibility for the fiscal multiplier. It presents a New Open Economy Macroeconomics model which is extended with the formation of 'deep habits' by individual households. Hereby, an inter-temporal...

This paper provides international evidence on time-variation in trend productivity growth, based on the dataset for hours worked constructed by Ohanian & Raffo (2012). Applying both the endogenous break tests of Bai & Perron (1998, 2003) and the Stock & Watson (1996, 1998) TVP-MUB methodology,...

Using a novel data set, we reassess the evidence for (or against) a key implication of the basic RBC model: that aggregate hours worked respond positively to a positive technology shock. Two novel aspects of the analysis are the scope (14 OECD countries) and the inclusion of data on both labor...

We construct a composite index to measure real activity of the Swiss economy on a weekly frequency. The index is based on a novel high-frequency data-set capturing economic activity across distinct dimensions over a long-time horizon. An adequate adjustment of raw data prior to deriving the...

This study uses trade data from Switzerland's Federal Customs Administration to examine the impact of Covid-19 on international goods trade between January and July 2020. We show that Swiss trade during that period fell by 11% compared to 2019 and that the contraction following the "Federal...

We develop a small-scale dynamic factor model for the Swiss economy based on an appropriately selected set of indicators. The resulting business cycle factor is in striking accordance with historical Swiss business cycle fluctuations. Our proposed model demonstrates a remarkable performance in...
