Back in the day, some innovative economists combined fancy inter-industry analysis with econometric frameworks. This merge had many regional economists hooked on! Now, many studies have emerged, all about using this innovative integrated framework to understand regional economies. They all have different ways of merging the input-output and econometric models. The goal is to get the best of both worlds and make some fancy predictions. This study? Well, it takes an attempt at using a technique called intersectoral demand variable (ISDV) to mix input-output analysis with a time-series model. We picked the economy of Illawarra in Australia for our experiment. And... The result is a super-duper dynamic model that's pretty good at predicting employment in different sectors. It's like having a crystal ball for the job market!
