In this paper, we study the effects of entry deregulation on firm innovation, using the business registration reform in China as a case in point. Entry deregulation has negative impacts on patent applications, and the effects are more pronounced for larger firms and older firms. Firms spend more...

In this paper, I examine the effects of China's civil examination system (keju) on modern-day innovation and firm dynamics. Using the variation in the density of jinshi (the highest exam qualification) and using the distance to the printing ingredients (pine and bamboo) as the instrumental...

In this paper, I study the effects of corruption on firm innovation, using a data set that covers the registration and patent application records of the universe of firms in China. I provide empirical evidence that corruption significantly deters innovation. Such effects are stronger for...

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...

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...

Facing scarcity of a production factor, a firm can develop technologies to either substitute the scarce factor (price effect) or complement the more abundant factors (market size effect). Whether the market size effect or the price effect dominates largely depends on the elasticity of...

Although both infrastructure and innovation play an important role in fostering a country's economic growth, discussion in the literature about how the two are connected is limited. This paper examines the impact of road density on firm innovation in China using a matched patent database at the...
