r Rural tourism s Urban tourism a Agriculture m Manufacture xi Domestic demand for good i yi Domestic supply of good i pi Price of good i L Labor endowment K Capital endowment l Land endowment, l =1 T Land used in agriculture n Natural Park, (n+T=1) u Aggregate utility level z Pollution emitted from manufacturing t Pollution tax t Tariff Mi Net import of tradable good i Summary of Notation
Summary of Functions • Aggregate Expenditure Function • Total Revenue Function
Aggregate Expenditure Function (1) • Homogenous of degree one in all prices • Concave in prices • Non-decreasing in prices, utility, pollution emission, and natural park
Aggregate Expenditure Function (2) • Shephard’s lemma, the demand for good i • Output demand is downward sloping • The shadow price of clean environment, or the marginal willingness for consumer to pay to for clean environment
Aggregate Expenditure Function (3) • The shadow price of natural park, or the marginal willingness for consumer to pay to preserve natural park: • Utility function
Total Revenue Function (1) • Homogenous of degree one in all prices • Homogenous of degree one in all factor endowments
Total Revenue Function (2) • Convex in prices • Concave in factor endowments • The supply of good i
Total Revenue Function (3) • Output supply is upward sloping • The quantity of pollution emitted
Total Revenue Function (4) • The wage of factor • Factor demand is downward sloping
Equilibrium Conditions (1) • The economy’s budget constraint total expenditure = total revenue [1]
Equilibrium Conditions (2) • Net import of tradable goods [2] to [5] • Good is imported if • Good is exported if
Equilibrium Conditions (3) • Pollution [6] • Land market [7] • Inverse world demand for rural tourism [8] • Inverse world demand for urban tourism [9]
Welfare Analysis (1) • Exogenous variables • are given at world market prices • Endogenous variables • are set by world demand for rural and urban tourism
Welfare Analysis (2) • Total differentiate [1], yield • Rearrange and using [2] to [6], yield [10]
Welfare Analysis (3) • Total differentiate [8], and rearrange, yield [11] [11’]
Welfare Analysis (4) • Similarly, total differentiate [9], yield [12] [12’] • Where, for Proportional change of tourism prices Proportional change of tourism import
Welfare Analysis (5) Own inverse elasticity of world demand for tourism Cross inverse elasticity of world demand for tourism Inverse elasticity of Natural Park to tourism prices Inverse elasticity of pollution to tourism prices
