The question asks about the difference between total factor productivity (TFP) in the Solow-Swan model and the stock of ideas in the Romer model. Option a: 'TFP grows but ideas are fixed.' In the Solow-Swan model, TFP is exogenous and typically treated as a fixed, long-run productivity parameter unless you alter technology over time through a stochastic process; the standard Romer framework instead endogenizes ideas, not fi......Login to view full explanation

Question7 In the Romer model, if Canada and Taiwan have the same proportion of researchers and the same knowledge efficiency parameter but Canada’s population is larger, then Taiwan has a higher per capita output growth rate. Canada has a higher per capita output growth rate. Canada’s level of income is greater than Taiwan’s. Canada has higher per capita income than Taiwan. each country’s per capita output grows at the same rate. ResetMaximum marks: 1 Flag question undefined

Question6 The growth rate of per capita GDP in the Romer model depends on the number of workers engaged in research. However, the country of Luxemburg, which has far fewer researchers than the U.S., grows at a rate faster than the U.S. and has a higher per capita GDP. How can the Romer model explain this difference in growth rates? This difference in growth rates is not consistent with the Romer model. The model fails to predict the facts. Due to the nonrivalry of ideas, the economy of Luxemburg grows because the model is based on ideas created throughout the world, not just within that country. The productivity of researchers or the share of workers engaged in research must be smaller in Luxemburg than in the U.S. Luxemburg is richer so according to the principle of transition dynamics, its economy should grow faster.
