Using data from multiple sources, we show that in Bangladesh, the increase in real wages, particularly female wages, has accelerated since the late 2000s, suggesting that the Lewis turning point (the point at which the labor market starts to shift in favor of workers) has arrived in Bangladesh....

Most of the poor in the developing countries are smallholder farmers. Improving their productivity is essential for reducing poverty. Despite small landholdings, a high degree of land fragmentation, and rising labor costs, agricultural production in China has steadily increased. If one treats...

Talhelm et al. (2014) provided an original rice theory to explain large psychological differences across countries and even within countries and their impact on innovation. However, their findings are subject to the problems of sample bias, measurement error, and model misspecification. After...

Innovations are a key driver of long-term economic growth. There has been an explosion of patent filings in China in the past three decades. But empirical studies on the pattern of innovations at the firm level are rather scant primarily due to lack of firm-specific patent data. We have made...

It is a daunting task to build institution and infrastructure over a short time period in developing countries. But in the absence of sound institutions and adequate infrastructure, it is difficult for economic transformation to take place. An alternative is to facilitate existing industrial...

The high level of inequality in China has been a focus of interest for policy makers and researchers. However, few studies have evaluated the trend since 2010. With changes in the economic structure and new policy tools introduced in recent years, a revisit of Chinese inequality should give us...

Because many rural poor live in areas far away from markets, we investigate whether better road access could help improve their livelihood and reduce rural poverty. We use three waves of a primary panel survey at the household level conducted in 18 remote natural villages in China to study how...

In many developing countries, gift expenses account for a substantial share of total household expenditures. As incomes rise, gift expenses are escalating in several developing countries. We develop a theoretical model to demonstrate how (unequal) income growth may trigger “gift competition”...

The literature has placed great emphasis on the advantages of competition on market efficiency while ignoring the downside of competition on health. Using a natural experiment in Taiwan, we show that excessive competition comes at a health cost. In the late 1940s, half a million soldiers...

While there is a large body of literature on the negative health effects of air pollution, there is much less written about its effects on cognitive performance for the whole population. This paper studies the effects of contemporaneous and cumulative exposure to air pollution on cognitive...
