This notes outlines how to solve Hayashi and Prescott (2007) "The 1990s: Japan's Lost Decade", extended with an exogenous population growth and labour-augmenting technical progress, using a Linear-Quadratic Approximation as in Ljungqvist and Sargent (2004).

This paper investigates the effect of market size on innovation activities across different durable good industries in the Chinese manufacturing sector. We use a potential market size measure driven only by changes in the Chinese income distribution which is exogenous to changes in prices and...

We analyze an economy where managers engage both in the adaptation of technologies from the world frontier and in innovation activities. The selection of high-skill managers is more important for innovation activities. As the economy approaches the technology frontier, selection becomes more...

A unified growth theory is developed that accounts for the roughly constant living standards displayed by world economies prior to 1800 as well as the growing living standards exhibited by modern industrial economies. Our theory also explains the industrial revolution, which is the transition...

Technology change is modeled as the result of decisions of individuals and groups of individuals to adopt more advanced technologies. The structure is calibrated to the U.S. and postwar Japan growth experiences. Using this calibrated structure we explore how large the disparity in the effective...

We develop a tractable dynamic model of productivity growth and technology spillovers that is consistent with the emergence of real world empirical productivity distributions. Firms can improve productivity by engaging in in-house R\&D, or alternatively, by trying to imitate other firms'...
