developmental models and evolutionary models

The methodology of ________ economics says that models should be based on predictions and not assumptions.

The cornerstones of all economic models that help negotiate a tradeoff between complexity and interpretability are scarcity assumptions rationality none of the other choices are correct

In the Romer Model (1990), if the level of technological knowledge is 1000, productivity parameter in the R&D sector is 0.0001, and wage paid to human capital is 50, what is the price of a new design from the R&D activities? (Show calculation steps.) In the Romer Model (1990), suppose the productivity parameter in the R&D sector is 0.0001 and the stock of human capital in the economy is 5000, of which 4000 is allocated to the manufacturing of the final goods. In the final goods production sector, output elasticity with respect to labor is 0.3 and output elasticity with respect to human capital is 0.5. Find the equilibrium interest rate.
