China's high corporate savings rate is commonly claimed to be a key driver for the country's large current account surplus. The mainstream explanation for high corporate savings is a combination of windfall profits in state-owned firms, especially in resource sectors, and mis-governance of...

This short essay surveys recent literature on the competitive saving motive and its broader economic implications. The competitive saving motive is defined as saving to improve one's status relative to other competitors for dating and marriage partners. Here are some of the key results of the...

Motivated by recent empirical work, this paper formalizes a theory of competitive savings - an arms race in household savings for mating competition that is made more fierce by an increase in the male-to-female ratio in the pre-marital cohort. Relative to the empirical work, the theory can...

China experiences an increasingly severe relative surplus of men in the pre-marital age cohort. The existing literature on its consequences focuses mostly on negative aspects such as crime. In this paper, we provide evidence that the imbalance may also stimulate economic growth by inducing more...

Large savings and current account surpluses by China and other countries are said to be a contributor to the global current account imbalances and possibly to the recent global financial crisis. This paper proposes a theory of excess savings based on a major, albeit insufficiently recognized by...

In partial equilibrium, a reduction in import barriers may be thought to lead to an increase in imports and a reduction in trade surplus. However, the general equilibrium effect can go in the opposite direction. We study how trade reforms affect current accounts by embedding a modified...

Sticky (or slow-adjusting) current accounts are observed for many countries. This paper explores the role of domestic factor market flexibility in understanding the phenomenon. To do so, we consider multiple tradable sectors with different factor intensities and allow substitution between...

Though the real exchange rate is a key price for most economies, our understanding of its determinants is still incomplete. This paper studies the implications of status competition in the marriage market for the real exchange rate. In theory, a rise in the sex ratio (increasing relative surplus...

In partial equilibrium, a reduction in import barriers may be thought to lead to an increase in imports and a reduction in trade surplus. However, the general equilibrium effect can go in the opposite direction. We study how trade reforms affect current accounts by embedding a modified...
