Testing for PPP: Should we use panel methods? [PDF]
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.

A mixed-methods comparison of the performance of Dutch PPP and non-PPP infrastructure projects
, 2022 Rijkswaterstaat, the Netherlands' major procurer of transport infrastructure, uses two primary contract types: Design and Construct (D&C) and Design-Build-Finance-Maintain (DBFM). In this chapter, we comparatively analyze the cost and time performance of these contract types using quantitative financial data on DBFM (N=12) and large D&C ...

Development of a Combined GPS/GLONASS PPP Method [PDF]
Journal of Positioning, Navigation, and Timing, 2014 Precise Point Positioning (PPP) is a stand-alone precise positioning approach. As the quality of satellite orbit and clock products from analysis centers has been improved, PPP can provide more precise positioning accuracy and reliability. A combined use of Global Positioning System (GPS) and Global Orbiting Navigation Satellite System (GLONASS) in PPP
