Содержание слайда: (6.1.) Structure of the Ricardo-Viner (R-V)
model of international trade
Structure of the world economy:
2 countries (h, f);
All final goods are tradable;
Production factors are immobile between the countries.
Structure of the production sector:
2 industries that produce 2 final homogeneous goods (X, Y);
3 production factors, 1 is a homogeneous, non-specific resource, mobile between industries (for example, labor - L), and 2 homogeneous, specific resources (for example, capital specific for each industry - Rx, Sy), immobile between industries;
Countries differ in absolute endowment of specific resource; endowment of mobile resource is the same for two countries: for example, Rxf>Rxh, Syf<Syh, Lf=Lh;
Specific features of the production technology:
CRS (an essential feature of functional dependence between production quantity and the quantity of the resources used in production);
Technologies differ among the industries, but not among the countries.
Structure of the household sector:
Tastes are identical and homogeneous among the households and the countries.
Market structure:
Perfect competition on the markets of production factors and of final goods.
№7 слайд
Содержание слайда: (6.1.) Exogenous parameters of the R-V model
(1) Exogenous parameters of the model :
Production technology - production functions :
Хh = fxh(Rxh, Lxh) = ARxhLxh(1-); Yh = fyh(Syh, Lyh) = BSyhLxh(1- );
Хf = fxf(Rxf, Lxf) = ARxfLxf(1-); Yf = fyf(Syf, Lyf) = BSyfLxf(1- ); where АВ, .
Resource endowment in each economy: Rxh, Rxf, Syh, Syf, Lh, Lf;
Preferences of representative household in each of the economies – utility functions:
Ui = Ui (Xi, Yi); i = h, f;
Market structure on the final goods markets – perfect competition.
Market structure on the resource market – perfect competition.
№8 слайд
Содержание слайда: (6.1.) Endogenous parameters of the R-V model
(2) Endogenous parameters of the model :
Equilibrium production and consumption of final goods in closed economies – Xha, Yha, Xfa, Yfa;
Equilibrium price ratios for final goods in closed economies – Pxha/Pyha, Pxfa/Pyfa;
Equilibrium production of final goods in the open economy – Xph*, Yph*, Xpf*, Ypf*;
Equilibrium consumption of final goods in the open economy – Xсh*, Yсh*, Xсf*, Yсf*:
If (Xc*-Xp*)>0 or (Yc*-Yp*)>0 – the good is imported;
If (Xc*-Xp*)<0 or (Yc*-Yp*)<0 – the good is exported;
Equilibrium world price ratio for final goods – Px*/Py*.

Содержание слайда: (6.1.) Specific features of
the Ricardo-Viner (R-V) model
(1) The Ricardo-Viner model – a version of neoclassical general economic equilibrium model.
(2) The main differences of R-V model from the other international trade models are connected to the production sector.
(3) The Ricardo-Viner model is a model of medium term (среднесрочного) adjustment of the economy to the exogenous shocks *.

Содержание слайда: (6.2.) Interrelation between change in the production factor quantities and final goods output in the Ricardo-Viner model
Graphical illustration 1 – interrelation between changes in quantities of specific resources and production quantities: conclusion
Exogenous increase in the supply of a specific factor will lead to an increase in the output of the commodity that uses this factor, and a decrease in the output of the other commodity;
Besides, any expansion of the endowment of a specific factor at constant commodity prices will lower the real return to both specific factors and increase the real return to the mobile factor;
The key feature is immobility of the resource between industries (the resource is specific), not resource intensity.

Graphical illustration 2 – interrelation between changes in quantities of mobile (non-specific) resource and production quantities

Содержание слайда: (6.2.) Interrelation between change in the production factor quantities and final goods output in the Ricardo-Viner model
Graphical illustration 2 – interrelation between changes in quantities of mobile (non-specific) resource and production quantities: conclusion
Exogenous increase in the supply of mobile factor will lead to an increase in the output of both commodities;
Besides, an increase in the endowment of the mobile factor will reduce its own real income and increase the real income of both specific factors.
№15 слайд
Содержание слайда: (6.3.) The pattern of international trade
(структура международной торговли) in the Ricardo-Viner model
The main assumption for simplification of the international trade structure analysis in the Ricardo-Viner model:
Countries differ in absolute endowment of specific production factors, mobile resource endowment being the same: for example, Rxf>Rxh, Syf<Syh, Lf=Lh.
№18 слайд
Содержание слайда: (6.3.) The pattern of international trade
(структура международной торговли) in the Ricardo-Viner model
The pattern of international trade in the Ricardo-Viner model: conclusion
In the specific-factors model, each country will export the good with the absolutely abundant stock of specific capital, assuming identical endowments of labor, the mobile factor;
With differences in labor endowments, trade patterns will depend on the nature of the production functions and on the allocation of capital (that is, on the stocks of specific factors);
Unlike the Heckscher-Ohlin-Samuelson model, trade structure in the Ricardo-Viner model depends on the immobile (specific) resource, not on the resource intensity *.

Содержание слайда: (6.4.) Interrelation between change in final goods prices and production factor prices
Graphical illustration - interrelation between change in final goods prices and mobile / specific production factor prices

№20 слайд
Содержание слайда: (6.4.) Interrelation between change in final goods prices and production factor prices
Graphical illustration - interrelation between change in final goods prices and mobile / specific production factor prices: conclusions
Exogenous increase in the commodity relative price results into
- increase in real return (real price) of the specific factor used in production of this commodity,
- decrease in real price of the other specific factor and
- has an indefinite impact on the real return of the mobile factor;
The conclusions depend on the factor mobility versus factor specificity, rather than factor intensities as in the H-O-S model.

Содержание слайда: (6.4.) Interrelation between change in final goods prices and production factor prices
Does the Stolper-Samuelson theorem hold in the Ricardo-Viner model?
The essential difference between medim- and long term effects from trade liberalization policy measures from the view point of gains and losses for the owners of production factors.
Explain this statement.
Does the factor price equalization theorem hold in the Ricardo-Viner model?
It does not hold.
Formulate factor price equalization theorem. Explain why it does not hold.
