Answer:
The Ricardian Model as described by David Ricardo is a model which explains trade between two countries and the products which they are most likely to export. The answer to your problem is given below.
Explanation:
(a) Calculate the autarky price of Goods in both countries: pG, and p*G.
The autarky price here means a price at which there will be no trade between the two countries:
Data:
The marginal product of labor in service industry of home country:
MPLS = 1
The marginal product of labor in goods industry of home country:
MPLG = 1
The marginal product of labor in service industry of foreign country:
MPLS* = 1/4
The marginal product of labor in goods industry of foreign country:
MPLG* = 1/2
The price of services in home country is:
Ps = $2
The price of goods in foreign country is:
Ps* = 12 Pesos
As per current exchange rate, the value of 12 Pesos is equal to $0.63.

Thus,
Ps* = $0.63
The autarky price of goods in both countries are calculated as follows:
Ps/PG = MPLS/MPLG
2/PG = 1/1
PG = $2
And,
Ps*/PG* = MPLS*/MPLG*
0.63/PG* = (1/4)/(1/2)
PG* = $1.26
