with , : w26181
We document that the nature of business cycles evolves over the process of development and structural change. In countries with large declining agricultural sectors, aggregate employment is uncorrelated with GDP. During booms, employment in agriculture declines while labor productivity increases in agriculture more than in other sectors. We construct a unified theory of business cycles and structural change consistent with the stylized facts. The focal point of the theory is the simultaneous decline and modernization of agriculture. As capital accumulates, agriculture becomes increasingly capital intensive as modern agriculture crowds out traditional agriculture. Structural change accelerates in booms and slows down in recessions. We estimate the model and show that it accounts well for bo...
|August 2013||Rational Housing Bubble|
This paper studies an economy inhabited by overlapping generations of homeowners and investors, with the only difference between the two being that homeowners derive utility from housing services whereas investors do not. Tight collateral constraint limits the borrowing capacity of homeowners and drives the equilibrium interest rate level down to the housing price growth rate, which makes housing attractive as a store of value for investors. As long as the rental market friction is high enough, the investors will hold a positive number of vacant houses in equilibrium. A housing bubble arises in an equilibrium in which investors hold houses for resale purposes only and without the expectation of receiving a dividend either in terms of utility or rent. The model can be applied to China, wher...
