Il lemma di Shephard (Shephard's lemma) è un'importante proprietà delle funzioni di costo che nell'economia della produzione permette di derivare, in quello che è noto come approccio duale (dual approach), le equazioni delle domande condizionali di input (conditional input demands), cioè la domanda di input vincolata ad un dato vettore di output, dalla funzione di costo.

Theorem. If a function F(x) is homogeneous of degree r in x then (∂F/∂xl)  Definition. In consumer theory, Shephard's lemma states that the demand for a particular good i for a given level of utility u and given prices p , equals the  Shephard's lemma gives a relationship between expenditure (or cost) functions and Hicksian demand. The lemma can be re-expressed as Roy's identity, which  A further remark on Shephard's Lemma. Susanne Fuchs-Selinger* lnstitut fiir Wirtschaftstheorie und Operations Research, Universitiit Karlsruhe, Karlsruhe  Jul 25, 2018 Shephard's lemma in economics. It is known that if the demand function is continuously differentiable, then the local existence of this equation  Shephard's lemma gives a relationship between expenditure (or cost) functions and Hicksian demand. The lemma can be re-expressed as Roy's identity, which  It is important to note that Shephard's Lemma 1.1.d is simply an application of imization as Shephard's Lemma plays in the theory of competitive cost minimiza-.
