Product Innovation, Product Diversification, and Firm Growth: Evidence from Japan’s Early Industrialization

We explore how firms grow by adding products. We leverage detailed data from Japan’s cotton spinning industry at the turn of the last century to do so. This setting allows us to fully characterize the type of differentiation (vertical or horizontal) of new product introductions as well as whether the product is within or outside of the firm’s prior technological capabilities. We find that trying to introduce innovative products beyond the firm’s previous technologically feasible set, even if such trials fail, is a key to firm growth. Indeed, it mostly facilitates growth through the firm’s later success in horizontal product diversification. In long-term outcomes, the right tail of the firm size distribution becomes dominated by firms that first moved into technologically challenging products and then later applied their newly acquired technical competence to horizontal expansion of their product portfolios. Two mechanisms through which this knowledge transfer occurs are greater production system flexibility and higher product appeal to downstream buyers. (JEL D22, L11,L67, N65, N85, O31, O33)

Industrial Policy in China: Some Intended or Unintended Consequences?

The authors explore the impact of a 2004 tax reform in China that reduced the value-added tax (VAT) on investment goods. Although the goal of the reform was to encourage upgrading of technology, results suggest there was no significant increase in fixed investment, new product introductions, or productivity. Rather, the authors find that firms shifted the composition of investment toward machinery and increased the capital intensity of production, which is consistent with a fall in the price of capital relative to labor. As a result, employment fell significantly in the treated provinces and sectors. Results are robust to a variety of approaches and suggest that the primary impact of the policy has been to induce labor-saving growth. In 2009, the VAT reform was extended to the rest of China.
