We build a novel endogenous growth model with information carrier technology, in which knowledge may be lost in storage and dissemination. In the asymptotic balanced growth path equilibrium, we establish two main findings. First, the growth rate of information carrier technology and the...

We develop a growth model that features the endogenous two-tier innovations of information carrier technology and production technology. Information carrier technology promotes production technology innovation and thus economic growth through improving the preservation and dissemination of...

We build an endogenous growth model with consumer-generated data as a new key factor for knowledge accumulation. Consumers balance between providing data for profit and potential privacy infringement. Intermediate good producers use data to innovate and contribute to the final good production,...

The digital economy’s functioning hinges upon the close collaboration of various core elements. Data, as a pivotal production factor, derives its value not in isolation but rather from its intricate connection to physical media, like data processors and storage devices. This paper introduces a...

We build an endogenous growth model to study the optimal design of data rights in a data economy. Analysis shows that the duration of data rights protection can significantly affect long-term economic growth through three channels: consumers' privacy concerns, the incentives to develop processed...

We propose a theory of rational "Rush", emphasizing the quantity of rational over-investment in contrast to the theory of irrational price "Bubble". We illustrate an important friction when financing breakthrough innovations: non-excludability and spillover of uncertain knowledge due to...

We model a dynamic data economy with fully endogenous growth where agents generate data from consumption and share them with innovation and production firms. Different from other productive factors such as labor or capital, data are nonrival not only among firms but also in their uses across...
