September 2020To Stay or to Migrate? When Becker Meets Harris-Todaro
with Pei-Ju Liao, Ping Wang, Yin-Chi Wang: w27767
Allowing migration activity as an integral part of demographic transition and economic development, we establish a locational quantity-quality trade-off of children and explore its macroeconomic consequences. We construct a dynamic competitive migration equilibrium framework with rural agents heterogeneous in skills and fertility preferences. We then establish and characterize a mixed migration equilibrium where high-skilled rural agents with low fertility preferences always migrate to cities, low-skilled with high fertility preferences always stay, and only an endogenously determined fraction of high-skilled/high fertility preferences or low-skilled/low fertility preferences ends up moving. By calibrating our model to fit the data from China, we find interesting interactions between ferti...
August 2018Mismatch and Assimilation
with Ping Wang, Tsz-Nga Wong: w24960
Income disparity across countries has been large and widening over time. We develop a tractable model where factor requirements in production technology do not necessarily match a country's factor input profile. Appropriate assimilation of frontier technologies balances such multi-dimensional factor input-technology mismatch, thus mitigating the efficiency loss. This yields a new measure for endogenous TFP, entailing a novel trade-off between a country's income level and income growth that depends critically on the assimilation ability and the factor input mismatch. Our baseline model accounts for 80%-92% of the global income variation over the past 50 years. The widening of mismatch and heterogeneity in the assimilation ability account for 41% and 20% of the global growth variation, where...
October 2017Educational Choice, Rural-urban Migration and Economic Development
with Pei-Ju Liao, Ping Wang, Yin-Chi Wang: w23939
Observing rapid structural transformation accompanied by a continual process of rural to urban migration in many developing countries, we construct a micro founded dynamic framework to explore how important education-based migration is, as opposed to work-based migration, for economic development, urbanization and city workforce composition. We then calibrate our model to fit the data from China over the period from 1980 to 2007, a developing economy featuring not only large migration flows but major institutional reforms that may affect work and education based migration differently. We find that, although education-based migration only amounts to one-fifth of that of work-based migration, its contribution to the enhancement of per capita output is larger than that of work-based migration...
Dynamic Trade, Endogenous Institutions and the Colonization of Hong Kong: A Staged Development Framework
with T. Terry Cheung, Theodore Palivos, Ping Wang, Yin-Chi Wang: w23937
To explore the interplays between trade and institutions, we construct a staged development framework with multi-period discrete choices to study the colonization of Hong Kong, which served to facilitate the trade of several agricultural and manufactured products, including opium, between Britain and China. Based on the historical data and documents that we collected from limited sources, we design our dynamic trade model to capture several key features of the colonization process and use it to characterize the endogenous transition from the pre-Opium War era, to the post-Opium War era and then to the post-opium trade era, which span the period 1773-1933. We show that while the low opium trading cost and the high warfare cost initially postponed any military action, the high valuation of t...
