Opdracht 4
Opdracht 4a
Gegeven:
De volgende relaties tussen vraag (qv), aanbod (qa) en prijs (p) gelden op de markt:
- Qv = –0,4 p + 0.04 Y + 5 (1)
- Qa = 0,6 p – 15 (2)
- Qv = Qa (3)
Qv = Vraag functie
Qa = Aanbodfunctie
Y verwijst naar het inkomen (Y = 500).
Vragen
4a) Wat is de algemene evenwichtsprijs? Hoe groot is de bijbehorende hoeveelheid die gevraagd
wordt (Qv) en de bijbehorende hoeveelheid die aangeboden wordt (Qa)?
Qv = Qa
-0,4p + 0,04Y + 5 = 0,6p - 15
-p + 0,04Y = -20
Y = 500
-p + 0,04 * 500 = -20
-p + 20 = -20
p = 40
4b) Veronderstel dat het evenwicht op de markt verstoord is door een stijging van het inkomen met
25%. Bereken het nieuwe evenwicht voor p, Qv and Qa.
Y = 500 * 1,25 = 625
