1. An economy has the following variables: Goods Market: Y=500 C=25 + 2/3 (Y-T)-100r I=120-300r G=75 T=50 a) Graphically draw (a rough sketch is fine) of the goods market. Assuming you start at the closed economy equilibrium what is the initial r, S, I? b) Suppose that there is a reduction of G by 25, What is the new r, S, I? Show this graphically. c) Starting with the initial information suppose instead that there is a reduction of I by 25, What is the new r, S, I? Show this graphically.

Question Another important aspect of Tourism Economics is the multiplier effect, which refers to the additional economic activity generated by tourism spending. When tourists spend money in a destination, it circulates through the local economy, benefiting not just the direct recipients of this spending but also other businesses and their employees. For example, tourists spending money in local restaurants support not only the restaurant staff but also local suppliers and their workers. The multiplier effect in Tourism Economics is essential because it: A) Reduces overall economic activity B) Only benefits the tourism sector C) Generates additional economic activity beyond the initial spending D) Leads to economic stagnation
