The geographical distribution of factors of production can have a profound impact on their mobility and, subsequently, on PES. If factors of production, especially labour and capital, are concentrated in specific regions or locations, their mobility might be limited. For instance, if a particular region specialises in car manufacturing and has most of the country's skilled automobile workers, it might be challenging for a sudden boom in another industry, say electronics, to attract these workers quickly. This geographical concentration can make the supply inelastic. Conversely, a more even distribution of factors across regions can enhance mobility, allowing for a more elastic supply as industries can adjust more readily to price changes.

Government policies and regulations can either facilitate or hinder the mobility of factors of production. For instance, policies that promote education and training can enhance labour mobility by equipping workers with diverse skills, allowing them to transition between industries more easily. On the other hand, strict immigration policies might limit labour mobility by restricting the inflow of foreign workers. Similarly, regulations that impose heavy taxes or duties on the import and export of machinery can limit capital mobility. In essence, government interventions can play a decisive role in determining how easily factors of production can move, thereby influencing the PES.

Sunk costs refer to costs that have already been incurred and cannot be recovered. In the context of spare capacity and PES, if a firm has made significant sunk investments in machinery or infrastructure that is currently underutilised, it might be more inclined to ramp up production when prices rise. This is because the firm would want to utilise its existing resources to the fullest and recover its sunk costs. As a result, the presence of significant sunk costs can make the supply more elastic, as firms with spare capacity are more responsive to price changes, aiming to maximise their returns on previous investments.

Some industries might have a more elastic supply in the short run due to the nature of their production processes and the resources they utilise. For instance, service-based industries, like software development or consultancy, might have a more elastic supply because they can quickly adjust their output by hiring more staff or increasing working hours. On the other hand, industries that rely heavily on natural resources or have longer production cycles, like agriculture or mining, might have a more inelastic supply in the short run. This is because they can't instantly increase their output in response to price changes due to the time it takes to extract resources or grow crops.

Technological advancement can significantly enhance the mobility of capital, thereby influencing the Price Elasticity of Supply (PES). As technology progresses, machinery and equipment often become more versatile and adaptable. For instance, with advancements in manufacturing technology, a single piece of machinery might be reconfigured to produce a variety of products. This adaptability means that capital (in this case, machinery) can be swiftly repurposed in response to market demands. As a result, the supply can adjust more rapidly to price changes, making it more elastic. In essence, technological progress can make capital more mobile, allowing producers to respond more flexibly to market conditions and thus influencing PES.
