We analyze the endogenous formation of patent pools among three patent owners and the associated welfare effects. Under a condition of synergistic three-patent combination, either a unique symmetric equilibrium or infinitely many asymmetric equilibria can arise when patents are fragmented. By...

This study investigates the long-term impact of artificial intelligence (AI) and machine learning (ML) patent intensity on firms' performance, focusing on innovation-driven competitive advantage. Using a panel of 20 technology-intensive firms from 2013 to 2023, this study employs eXtreme...

Innovation is widely believed to play an important role in addressing climate change. Nevertheless, estimating such effects is difficult due to the endogeneity of innovation measures. I use a novel shift-share instrument building from cross-border patent citations to deal with this endogeneity....

This study investigates the relationship between Artificial Intelligence (AI) and innovation inputs in Spanish manufacturing firms. While AI is increasingly recognized as a driver of productivity and economic growth, its role in shaping firms’ innovation strategies remains underexplored. Using...

The target responsibility system of environmental protection, introduced during the 11th Five-Year Plan period, is a key feature of China's environmental regulation policy framework. Guided by the principle of high-quality development, this system addresses the challenge of incentivizing green...

We find that patents registered by multinational enterprises (MNEs) in tax havens help avoid taxes in the EU but fail to increase the total factor productivity (TFP) of EU-located group members. We conclude that many of those patents' prime purpose is not to make technology available and then...

Regional coordinated development necessitates achieving sustained economic growth and balanced development through regional synergy. In the digital economy era, digital knowledge constitutes a critical source of technological progress and represents a significant determinant of regional...

The recent surge in global financial and patent innovations and rising CO2 emissions in the global energy sector have drawn significant attention to China's transportation industry. This study examines how financial innovations (FINI), patent innovations (PTIN), and bioenergy (BIOE) affect CO2...

China's patenting activity has surged over the past two decades, yet questions remain about the quality and sources of innovation. We develop a new method to measure the importance of a patent for innovation, based on the use of a Large Language Model to process patent text data and a new theory...

This study investigates the relationship between Artificial Intelligence (AI) and innovation inputs in Spanish manufacturing firms. While AI is increasingly recognized as a driver of productivity and economic growth, its role in shaping firms' innovation strategies remains underexplored. Using...
