We have investigated two large Japanese firms with their patent data, technological histories and product sales data of over 30 years especially in terms of intra-firm technology diversification and interactions between multiple technological trajectories. Patent data showed the process of emergencies of technological trajectories and interactions (cross-fertilization) between them quantitative...

a diversification of the country’s export structure through the concerted development of its export-oriented manufacturing capacity could offer a viable alternative, as also stipulated in the country’s second socioeconomic and cultural development plan, by increasing the resilience of its economy against external shocks, supporting employment creation and technological innovation, and adding do...

This paper examines firms and the products they manufacture — and abandon — over time. We find strong relationships between product switching and a number of microand macroeconomic variables, including firm performance, aggregate manufacturing growth and product diversification. Most importantly, product switching is a very important — and active — margin of firm adjustment that is positively c...

Several definitions of diversification exist. Such motivation for diversification could apply Typically, the concept is dynamic and refers to-the equally to proprietary or cooperative forms of relationship among various activities or enterprises in business. which the firm is engaged. As new activities are The purpose of this paper is to quantitatively acquired by a firm from some existing base...

We explore how firms grow by adding products. leverage detailed data from Japan’s cotton spinning industry at the turn of last century to do so. This setting allows us fully characterize type differentiation (vertical or horizontal) new product introductions as well whether is within outside firm’s prior technological capabilities. find that trying introduce innovative products beyond previous ...

So it is in the American economy. Just to retain its relative position, a business firm must go through continuous growth and change. To improve its position, it must grow and change at least "twice as fast as that." According to a recent survey of the ioo largest United States corporations from 1909 to 1948, few companies that have stuck to their traditional products and methods have grown in ...

Countries differ markedly in the diversification of their exports. Products differ in the number of countries that export them, which we define as their ubiquity. We document a new stylized fact in the global pattern of exports: there is a systematic relationship between the diversification of a country’s exports and the ubiquity of its products. We argue that this fact is not implied by curren...

The present paper investigates relatedness and coherence with reference to both product and technological diversification. In particular, it is argued that: (i) relatedness can be disentangled into three dimensions: industry-, technologyand firm-specific; and that (ii) coherence refers to both product and technological diversification. We provide empirical support of our premises with a study o...
