Consider two economies that are identical in all dimesions -- the same population, same saving rate, the same production function, etc, -- except for the fact that one has a level of productivity that is twice as high as the other, that is Ah = 2Al . Assume both economies are in their steady states. what is the relationship between the levels of income per worker in these two economies?

Solutions

Expert Solution

There are 2 ecoonomies that are identical in population, saving rate and same production function. The level of productivity is different. In one economy the level of productivity is twice as hish as other Ah=2Al.

Both economies are in the steady state. The percapita income at steady state in 2 economies are

Economy 1:

y1*=ka(sAh/d+n)(a/1-a)

y1*=ka(2sAl/d+n)(a/1-a)

k is the per capita capital, s is the saving rate, Ah is the productivity of one country, d is the deprication rate and n is the population growth rate , a is the share of capital in the output.

Economy 2:

y2*=ka(sAl/d+n)(a/1-a)

k is the per capita capital, s is the saving rate, Ah is the productivity of one country, d is the deprication rate and n is the population growth rate , a is the share of capital in the output.

If all factors are same in 2 economies then comapring y1 and y2 we can say y1 is higher than y2 by a multiple of

2(a/1-a). The multiple value depends on the capital share of the output in the economy.

Two period saving model) Consider an economy populated by identical people who live for two periods. They have preferences over consumption of the following form: U=ln(c1) +βln(c2), where ct denotes the stream of consumption in period t. They also receive an income of 50 dollars in period 1 and an income of 55 dollars in period 2. They can use savings to smooth consumption over time, and if they save, they will earn an interest rate of 10% per period....

This question deals with internal economies of scale, when firms are not all identical and there is an option to engage in horizontal foreign direct investment (FDI). This entails paying some fixed cost (F) to set up a plant in a foreign country. Setting up a plant means that firms do not have to pay the per unit export cost (t) when selling units of output to the foreign country. You can think of firms as differing in terms of...
