Extracting Business Cycle Fluctuations: What Do Time Series Filters Really Do?
Various methods are available to extract the “business cycle component” of a given time series variable. These methods may be derived as solutions to frequency extraction or signal extraction problems and differ in both their handling of trends and noise and their assumptions about the ideal time-series properties of a business cycle component. The filters are frequently illustrated by applicat...
متن کاملNber Working Paper Series Measuring What Employers Really Do about Entry Wages over the Business Cycle
In models recently published by several influential macroeconomic theorists, rigidity in the real wages that firms pay newly hired workers plays a crucial role in generating realistically large cyclical fluctuations in unemployment. There is remarkably little evidence, however, on whether employers’ hiring wages really are invariant to business cycle conditions. We review the small empirical li...

متن کاملWhat do scaffold proteins really do?
Scaffold proteins play an important role in coordinating signal transduction cascades. However, their exact mechanism of action and the ultimate effect they have on the signal output remain unclear. Ferrell discusses how computer simulations have provided insight into the multiple possible functions that scaffold proteins may have. What remains is to test the predictions in real cells to determ...
متن کاملWhat Does PLIER Really Do?
MOTIVATION Our goal was to understand why the PLIER algorithm performs so well given its derivation is based on a biologically implausible assumption. RESULTS In spite of a non-intuitive assumption regarding the PM and MM errors made as part of the derivation for PLIER, the resulting probe level error function does capture the key characteristics of the ideal error function, assuming MM probe...
