4. The catch-up effect

Consider the economies of Hermes and Gribinez, both of which produce glops of gloop using only tools and workers. Suppose that, during the course of 30 years, the level of physical capital per worker rises by 5 tools per worker in each economy, but the size of each labor force remains the same.

Complete the following tables by entering productivity (in terms of output per worker) for each economy in 2020 and 2050.

Initially, the number of tools per worker was higher in Hermes than in Gribinez. From 2020 to 2050, capital per worker rises by 5 units in each country. The 5-unit change in capital per worker causes productivity in Hermes to rise by a (larger/smaller) amount than productivity in Gribinez. This illustrates the (natural resources/human captial/catch-up/technology) effect.

In the model Yi = β0 + β1X1 + β2X2 + β3(X1 × X2) + ui, suppose X1 increased by 1 unit, then expected effect for Y is (How much Y will increase?):

A. β1.

B. a change in X by one unit is associated with a 100 β1 % change in Y.

C. a change in X by one unit is associated with a β1 change in Y.

D. a 1% change in X is associated with a 100β1 % change in Y.
