Korspriser

Korspriser is a term used in some Nordic-language economic texts to refer to the prices of related goods that influence the demand for a particular good. The concept sits within the broader idea of cross-price effects. In this usage, korspriser describe how a change in the price of one good affects the quantity demanded of another good, depending on whether the goods are substitutes or complements. While the English-language literature typically uses cross-price or cross-price elasticity of demand, korspriser is a regional term that may appear in Swedish, Norwegian, or Danish pricing analyses. Because terminology varies, the same concept may be labeled korspriser, cross-pris, or korspriselasticitet in different sources.

Several applications exist: firms studying competitive pricing compare korspriser across related products to anticipate market share changes when rivals adjust prices; policymakers consider korspriser when evaluating indirect effects of taxes or subsidies on related markets.

Measurement follows the same principle as cross-price elasticity: E_xy = (%ΔQx)/(%ΔPy). A positive value indicates substitutes, a negative value indicates complements; larger absolute values signal stronger interdependencies.

Examples: An increase in coffee price may raise demand for tea (positive cross-price elasticity). A rise in milk price may reduce cereal consumption if milk is a complement for cereal.
