The paper discusses methodological questions related to econometric time-series modelling of I(2) data. Long-run and medium-run relationships between two general price indices, the US CPI and WPI and four commodity prices indices, the WBI, CRBI, GSCI, and ECI are investigated in a multivariate...

Based on a money market analysis the paper discusses possible pitfalls in acroeconomic inference related to inadequate stochastic model formulation. A number of questions related to concepts such as empirical and theoretical steady-states, speed of adjustment, feed-back and interaction effects,...

This paper examines the interrelations between purchasing power parity, uncovered interest parity, the term structure of interest rates and the Fisher real interest rate parity using cointegration analysis. Dynamic adjustment and feed-back effects are estimated jointly in a full system of...

Asset prices undergo long swings that revolve around benchmark levels. In currency markets, fluctuations involve real exchange rates that are highly persistent and that move in near-parallel fashion with nominal rates. The inability to explain these two regularities with one model has been...

Some recent developments in the macroeconometric analysis of time series are discussed in the light of Haavelmo (1944). Experimental design in econometrics is discussed and related to the case of passive observation. The general ideas are illustrated with an analysis of the long-run and...

Asset prices tend to undergo wide swings around long-run equilibrium values, which can have detrimental effects on the real economy. To get a better understanding of how the financial sector and the real economy interact, this paper models the long swings in the Swiss franc-US dollar foreign...
