aggregated observations (see Working (1960)). This paper investigates the effect of aggregation on the relation between variables … (cointegration). It will be shown that aggregation does not distort the cointegration relation while some other features of the data … cointegration analysis seems to be robust against various aggregation strategies. -- cointegration ; aggregation ; time series …

asymptotic theory based on large aggregation intervals we derive conditions for a correspondence between both concepts. These … examining the consequences of temporal aggregation in (possibly) Granger causal systems of variables. Our approach is to compare … results allow us to differentiate between spurious contemporaneous correlation arising because of aggregation, and true …

is provided by a productivity-based model of the real value of the euro. Some panel regression estimates of the … relationship between intercountry relative productivity differentials and real exchange rates is presented. Using these estimates … to conduct some calculations, one comes to the conclusion that unless drastic changes to productivity trends occur, there …
