Empirical Economics, 2001 A common finding in the empirical literature on the validity of purchasing power parity (PPP) is that it holds when tested for in panel data, but not in univariate (i.e. country specific) analysis. The usual explanation for this mismatch is that panel tests for unit roots and cointegration are more powerful than their univariate counterparts.

Assessment of the Feasibility of PPP-B2b Service for Real-Time Coseismic Displacement Retrieval
Remote Sensing, 2021 Traditional coseismic displacement retrieval generally uses real-time kinematic (RTK) and precise point positioning (PPP) services. However, both RTK and real-time PPP need a network link to transmit the corrected data.

Measuring Global Poverty: Why PPP Methods Matter [PDF]
Review of Economics and Statistics, 2013 Abstract We present theory and evidence to suggest that, in the context of analyzing global poverty, the EKS approach to estimating purchasing power parities yields more appropriate international comparison of real incomes than the Geary-Khamis approach.
