Università degli Studi di Cagliari Facoltà di Scienze Economiche, Giuridiche e Politiche Dipartimento di Scienze Sociali e delle Istituzioni Corso di Laurea in Scienze Politiche Prof. Romano Piras ESAME DI ECONOMIA POLITICA 6 settembre 2016 Cognome ________________________ Nome _________________________ Matricola n. _______________ Esercizio 1 Giovanni consuma frutta (bene x) e verdura (bene y). Il prezzo unitario della frutta è pari a 3€ al chilo, quello della verdura è pari a 1,5€ al chilo. Le sue preferenze sono rappresentate dalla funzione di utilità U(x, y)=10xy e il tasso marginale di sostituzione tra i due beni è pari a y/x. 1. Scrivete e rappresentate graficamente il vincolo di bilancio di Giovanni, sapendo che il reddito di cui dispone è pari a 300€ mensili. Indicate bene il valore delle due intercette e dell’inclinazione del vincolo di bilancio. Ricordate di indicare il bene x sull’asse orizzontale ed il bene y su quello verticale. ________________________________________________________________________________________________ ________________________________________________________________________________________________ ________________________________________________________________________________________________ ________________________________________________________________________________________________ ________________________________________________________________________________________________ ________________________________________________________________________________________________ ________________________________________________________________________________________________ ________________________________________________________________________________________________ ________________________________________________________________________________________________ ________________________________________________________________________________________________ ________________________________________________________________________________________________ ________________________________________________________________________________________________ ________________________________________________________________________________________________ ________________________________________________________________________________________________ ________________________________________________________________________________________________ ________________________________________________________________________________________________ ________________________________________________________________________________________________ ________________________________________________________________________________________________ ________________________________________________________________________________________________ 2.
