The 2005 International Comparison Program's (ICP) estimates of economy-wide purchasing power parity (PPP) are based on parity estimates for 155 basic expenditure headings, mainly estimated using country product dummy (CPD) regressions. The estimates are potentially inefficient and open to...

The empirical analysis in "International R&D Spillovers" (Coe and Helpman, 1995) is first revisited by applying modern panel cointegration estimation techniques to an expanded data set that we have constructed for the purpose of this study. The new estimates confirm the key results reported in...

We consider a cointegrating regression in which the integrated regressors are messy in the sense that they contain data that may be mismeasured, missing, observed at mixed frequencies, or have other irregularities that cause the econometrician to observe them with mildly nonstationary noise....

Sample surveys are often affected by missing observations and non-response caused by the respondents' refusal or unwillingness to provide the requested information or due to their memory failure. In order to substitute the missing data, a procedure called imputation is applied, which uses the...

Utilizing a new survey of employers, this paper examines how and why establishments differ in their willingness to permit an older full-time white-collar worker to take phased retirement. Phased retirement means that an older worker remains with his or her employer while gradually reducing work...

This paper examines whether the empirical evidence supports the strategic bequest motive, as opposed to pure altruism, using SHARE data on ten European countries. The availability of internationally comparable data, as in SHARE, allows exploiting the cross-country variability in inheritance laws...
