The monetary policy literature assumes increasingly that policies are formulated according to the timeless perspective (Woodford, 1999a). However, treating the auxiliary state variables that characterize the timeless perspective equilibrium appropriately when evaluating policy performance, this paper shows that discretionary policymaking can be superior to timeless perspective policymaking and ...

We present an analysis of Chandra ACIS observations of the field of TeV J2032+4130, the first unidentified TeV source, detected serendipitously by HEGRA. This deep (48.7 ksec) observation of the field follows up on an earlier 5 ksec Chandra director’s discretionary observation. Of the numerous point-like X-ray sources in the field, the brightest are shown to be a mixture of early and late-type ...

Data Envelopment Analysis (DEA) is used to measure the relative efficiency of the fourteen police precincts in Taipei city, Taiwan. Our results indicate how DEA may be used to measure these police precincts from commonly available police statistical data for the years 1994, 1995, and 1996. To sharpen our efficiency estimates, we use window analysis, slack variable analysis, and output-oriented ...

Discretionary policymakers cannot manage private-sector expectations and cannot coordinate the actions of future policymakers. As a consequence, expectations traps and coordination failures can occur and multiple equilibria can arise. To utilize the explanatory power of models with multiple equilibria it is first necessary to understand how an economy arrives to a particular equilibrium. In thi...

When corporate insiders sell their stock in quantities that deviate from firm-specific trends, their trades are more likely to precede bad news over a horizon of several months, but not in the short run. This is consistent with insiders avoiding “suspicious timing” when engaging into “suspicious amounts” of trading, the combination of which would likely result in Rule 10b-5 securities lawsuits....
