State Kaldor’s stylized facts (4 of them). Derive their implications for the share of national income paid to the owners of capital, the capital income share. Assume firms combine capital and labor to produce output according to Y = K α N 1−α where α is the elasticity of output to capital, i.e. the percentage change in output for a given percentage change in capital. What type of data would be informative of the value of this elasticity? Explain your answer and any assumptions you may need to reach your conclusion.
Kaldor's facts are six statements about economic growth, proposed by Nicholas Kaldor in his article of 1957. He described these as "a stylised view of the facts", which coined the term stylized fact.
Stylized facts of economic growthEdit
Nicholas Kaldor summarized the statistical properties of long-term economic growth in an influential 1957 paper.[1] He pointed out the 6 following 'remarkable historical constancies revealed by recent empirical investigations':
Kaldor did not claim that any of these quantities would be constant at all times; on the contrary, growth rates and income shares fluctuate strongly over the business cycle. Instead, his claim was that these quantities tend to be constant when averaging the data over long periods of time. His broad generalizations, which were initially derived from U.S. and U.K. data, but were later found to be true for many other countries as well, came to be known as 'stylized facts'.
These may be summarized and related as follows:
