Pro-poor growth or poverty trap? : estimating intergenerational income mobility in rural Philippines

Using an intergenerational database covering nearly a quarter of a century, we explored the degree of intergenerational income mobility among individuals who had grown up in rural Central Luzon, the Philippines. We found that the intergenerational income elasticity is significantly lower than unity, at roughly 0.23, indicating that the average income growth rate is higher for children born to poorer families. The detailed analysis, however, revealed that its magnitude significantly varies across percentiles in a U-shape. The results provide supporting evidence of multiple equilibria or poverty trap.

The middle-income trap from the viewpoint of trade structures

In this study, we try to elucidate the middle-income trap from the viewpoint of international trade. We conduct regression analyses on the relationship between income level and net export ratios for different types of goods for trapped and non-trapped samples separately. Our findings indicate that industrial upgrading appears to occur exactly as depicted by the flying-geese model for non-trapped countries while trapped countries tend to depend on the export of primary commodities, and industrialization appears to be driven by forward linkages to processed goods and a narrow base. The results of our analyses suggest that the middle-income trap is a form of Dutch disease or a 'resource curse' in the middle-income stage.

Avoiding the middle income trap : indigenous innovative effort vs foreign innovative effort

This paper investigates how innovation potential of a country contributes to avoid or escape the middle income trap. We measure innovation potentials of 77 countries from 1975 to 2010 from patent data. Then, we test whether indigenous innovative efforts or foreign ones help avoid and escape middle income traps
