The phrase "demand shifter" is correct and usable in written English.
It can be used in economic contexts to refer to factors that cause a change in demand for a product or service.
Example: "Changes in consumer preferences can act as a demand shifter, leading to increased sales for certain products."
Alternatives: "demand influencer" or "demand determinant".
In order to identify both the supply and the demand equation, we would need both a variable (or shifter) Z entering the demand equation but not the supply equation (e.g. in agricultural economics it is common to use weather variables), and X entering the supply equation but not the demand equation (e.g. in agricultural economics a common approach is to introduce income as demand shifter).
Our control variables are competition, potential patient capacity (describing firm size), average rental rate (a cost shifter) and the amount of disabled individuals receiving physiotherapy (a demand shifter).
In other words, we need to introduce Z, a demand shifter (e.g. income) and X, a supply shifter (e.g. weather variable): textrm{demand:} Q=a_{1}+b_{1}P+c_{1}Z, ,;,, textrm{supply:} Q=a_{2}+b_{2}P+c_{2}X, with positive b 2 and negative b 1.
For instance, while we need demand shifters to estimate the slope of the supply, we need supply shifters to estimate the slope of the demand.
These perceived benefits act as demand shifters and enter the demand function through the 'tastes' component.
In the health economics literature, D variables are often referred as demand shifters and C variables are referred as cost shifters.
D i again is a (set of) demand shifters (ranging over all insurers), and C h is a set of hospital product-specific control variables (cost shifters).
To capture demand shifters, we construct indicators for the relative importance of the competitive segment for a specific hospital or insurer.
Most studies follow the structure conduct performance (SCP) tradition and estimate a reduced form model in which price or margins are regressed on control variables (mostly cost and demand shifters) and a measure of either buyer or seller concentration.
Demand shifters: Changes in disposable income Changes in tastes and preferences - tastes and preferences are assumed to be fixed in the short-run.
These demand function shifters reflect changes in consumer preferences or the implementation of stricter legal sustainability criteria in the EU (or other markets) that would reduce the imports of palm oil from Indonesia.
