Improving Reliability and Assessing Performance of Global Navigation Satellite System Precise Point Positioning Ambiguity Resolution [PDF]
, 2018 Conventional Precise Point Positioning (PPP) has always required a relatively long initialization period (few tens of minutes at least) for the carrier-phase ambiguities to converge to constant values and for the solution to reach its optimal precision ...

Broke Autocrats, Broken Elections: Trade Shocks and Electoral Fraud in Autocracies
Economics &Politics, EarlyView.ABSTRACT We argue that when terms‐of‐trade (ToT) shocks reduce resource rents, autocrats lose the fiscal capacity to sustain loyalty through patronage and increasingly rely on electoral manipulation as a survival strategy. We present a simple model in which rents finance patronage in normal times, while adverse shocks reduce the effectiveness of ...
