The article attempts to show the role of the patent system in the internationalization of diffusion of technical knowledge. Its purpose is to analyse, use of international technical knowledge made available through patent systems, by Polish companies that are inventively active. For its...

Infl ows of foreign knowledge are the key for developing countries to catch up with the world technology frontier. In this paper, I construct a simple tractable model to analyze (a) the incentives of foreign fi rms to bring their know-how to a developing country and (b) the incentives of...

The aim of this paper is to investigate the productivity impact of business visits, relative to traditional drivers of productivity enhancement, namely capital formation and R&D. To carry out the analysis, we combine unique and novel data on business visits sourced from the U.S. National...

In the past several decades, the U.S. economy has witnessed a number of striking trends that indicate a rising market concentration and a slowdown in business dynamism. In this paper, we make an attempt to understand potential common forces behind these empirical regularities through the lens of...

This paper examines the trends in geographic localization of knowledge spillovers via patent citations, extracting multiple cohorts of new sample US patents from the period of 1976-2015. Despite accelerating globalization and widespread perception of the "death of distance," our matched-sample...

This paper examines the trends in geographic localization of knowledge spillovers via patent citations, considering US patents from the period of 1976-2015. Despite accelerating globalization and widespread perception of the \death of distance," our multi-cohort \matched-sample" study reveals...

The diffusion of innovations is supposed to dissipate inventors' rents. Yet in many documented cases, inventors freely shared knowledge with their competitors. Using a model and case studies, this paper explores why sharing did not eliminate inventors' incentives. Each new technology coexisted...

We provide a unified framework for quantifying the cross country and cross-sector interactions among trade, innovation, and knowledge diffusion. We study the effect of trade liberalization in a multi-country, multi-sector endogenous growth model in which comparative advantage and the stock of...

In this paper I propose a novel abstract mechanism for the creation and diffusion of knowledge and use an agent based modelling approach to explore it. The mechanism takes into account the relation between the phenomena that agents attempt to explain and the stocks of knowledge available in a...

This paper uses a large language model to develop an ex-ante measure of the commercial potential of scientific findings. In addition to validating the measure against the typical holdout sample, we validate it externally against 1.) the progression of scientific findings through a major...
