Abstract
This study examines inflation dynamics in Indonesia, a large archipelagic country, using the Phillips curve specification. Utilising province-level data from 2015 to 2019, the analysis accounts for regional interaction across Indonesian provinces and estimates spatial spillovers. To address the challenges of applying spatial methods to the world's largest archipelagic nation, two new approaches for the spatial weight matrix criteria are introduced: contiguity-based from artificial boundaries (Thiessen polygons) and trade-based from the Interregional Input–Output Tables. Furthermore, exploiting a new dataset, the study contrasts alternative measurements of inflation and output gap. These distinctions yield new findings. The results indicate the presence of a conventional Phillips curve in Indonesia. Different measures of inflation and the output gap have distinct spatial spillover effects.
期刊介绍:
Economic Papers is one of two journals published by the Economics Society of Australia. The journal features a balance of high quality research in applied economics and economic policy analysis which distinguishes it from other Australian journals. The intended audience is the broad range of economists working in business, government and academic communities within Australia and internationally who are interested in economic issues related to Australia and the Asia-Pacific region. Contributions are sought from economists working in these areas and should be written to be accessible to a wide section of our readership. All contributions are refereed.
