Our finаl shоrt prоblem invоlves building internаtionаl trade into a model of supply and demand.  We consider what happens in the market for widgets when imports expand supply.  First, we describe the relationship between the domestic supply of widgets and the price with the equation qdomS = 3p - 10. The relationship between the demand for widgets and their price is given by the equation qD = 150 - 5p. First, solve for the market equilibrium before trade: we have p0* = [p0] and q0* = [q0].  Total revenue for domestic producers here is obtained by multiplying the price by the quantity of domestic widgets sold: $[tr1].  . Next, we describe the relationship between the foreign supply of widgets and the price with the equation qforS = 2p. To consider the total supply of widgets, we must have qtotS = qdomS + qforS, where each part of the right-hand side is given above.  Simply add these parts together to get qtotS.  To find the new price and quantity sold after trade, set qtotS = qD.  Here, in the new equilibrium, we have p1* = [p1] and q1* = [q1].  To calculate the quantity of domestic widgets sold after trade, plug p1* into qdomS.  Domestic suppliers are able to sell [qdom] widgets here for a total revenue of $[tr2].  Foreign suppliers are able to sell [qfor] widgets (obtained in an equivalent manner to domestic suppliers) for a total revenue of $[tr3].  Does trade increase or decrease revenue for domestic suppliers?  Does it increase or decrease total revenue?
