The Shapiro-Stiglitz model plays an important role in the employment theory. Woodford pointed out the theoretic limitation of the linear worker's utility function in that model. He questioned the model's implication of the secular decline in the unemployment rate when such rate was in fact...

Population growth induces structural transformation. We posit two-sector growth models where land is a fixed production factor. When two sectoral goods are consumption complements, population growth pushes production factors towards the sector with stronger diminishing returns to labor through...

This paper uncovers the mechanism and assumptions underlying how population growth induces structural transformation. We construct two-sector models that give analytically tractable closed-form solutions. If sectoral goods are consumption complements, population growth induces a more than...

We develop a unified growth theory with Industrious Selection to explain the Five Revolutions in the development process (Agricultural Revolution, Structural Transformation, Industrial Revolution, Industrious Revolution, Demographic Revolution) and the Two Divergences in Eurasia (Little...

We develop a unified growth theory for the Western Hemisphere during the colonization era. We posit a unified growth model with transatlantic migration and slavery trade to reconcile development in the Thirteen Colonies/United States during AD1700-AD1860. Then we apply the model across American...

Rise of Women, industrialization and demographic transition are integral components in a nation’s development. We posit a two-sector unified growth model with endogenous female empowerment to study the interrelationship between women and development. Female empowerment would hamper fertility,...

Expansionary monetary policy is ineffective in a liquidity trap. In another case, which we call a “reserve trap,” money supply increase is trapped in bank reserves; there is no credit expansion through the banking system. In such case, quantitative easing (QE) will not boost credit to the...
