20.500.12556/DKUM-94102 Inflation, inflation uncertainty and economic growth in Tunisia nonlinear modelling framework Inflacija, inflacijska negotovost in gospodarska rast v Tuniziji: nelinearni model Inflation uncertainty is a critical factor influencing not only the market mechanisms but also the economic activity efficiency. In this paper, we investigated the relationship between inflation and growth to capture the impact of inflation uncertainty in Tunisia. The study relied on a dataset covering the period 1984.01-2018.08 and was characterized by a nonlinear specification. We used Hansen’s (2001) Threshold Regression (TR) analysis to determine one threshold effect of inflation on growth while explaining the role of inflation uncertainty in the whole process. This study concluded that an optimal inflation rate does exist. Under this rate, a little rise in inflation may enhance economic growth, allowing an adverse impact of inflation uncertainty. Above the critical threshold of 3%, it was revealed that inflation and inflation uncertainty play opposite roles: while the former harms growth, the latter benefits it. Thus, we cannot sustain the Friedman-Ball hypothesis for the two regimes. To the best of the authors’ knowledge, this is the first study that aimed to investigate the simultaneous effects of inflation and inflation uncertainty on growth in Tunisia using a non-linear methodology. This study aims to fulfil the knowledge gap of such studies for developing countries. threshold regression model inflation inflation uncertainty economic growth Tunisia pragovni regresijski model inflacija negotovost glede inflacije gospodarska rast Tunizija true false true Angleški jezik Slovenski jezik Znanstveno delo 2025-08-01 14:22:54 2025-08-01 14:22:54 2026-03-12 15:18:28 0000-00-00 00:00:00 2025 0 0 str. 44-57 no. 2 Vol. 71 jun. 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-06-01 336.748.12(611) 244625923 10.2478/ngoe-2025-0011 0547-3101 https://journals.um.si/index.php/oe/article/view/5263 1 404c0a3d-6ed2-11f0-b4b0-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=194687 RAZ_Boujelbene_Thouraya_Dammak_2025.pdf RAZ_Boujelbene_Thouraya_Dammak_2025.pdf 1 01ECCB2111F55A0F61D3FD932031026F d3b4e31dcdc69fccef5523e9355098e92a8076de35c33cb1fd6247a4c804b47b 511b9c5a-6ed2-11f0-b4b0-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=194688 Ekonomsko-poslovna fakulteta Naše gospodarstvo Naše gospodarstvo 0 0 0
