Based on patent data and industry specific energy prices for 18 OECD countries over 30 years we investigate on an industry level the impact of energy prices on green innovation activities. Our econometric models show that energy prices and green innovation activities are positively related and...

In a first step, we developed based on existing theoretical and empirical literature a series of hypotheses with respect to the relative importance of possible determinants of exploration and exploitation of knowledge in collaboration with universities and tested them on Swiss firm data. In a...

Based on a comprehensive data set comprising 13 countries, 22 industries and a period of 30 years we investigate the impact of internal and external knowledge pools of both green and ‘other than green’ technologies on green patent activities. It turned out that the internal green knowledge...

We propose a new patent-based measure of knowledge spillovers that calculates technological proximity based on firms that were identified via patent backward citations links. We argue that this measure has a couple of advantages as compared to the 'standard' measure proposed by Jaffe: First, it...

This paper investigates the R&D persistence of R&D active firms in different markets with different intensities of competition, based on firm-level panel data for the period 1996-2008. In a dynamic setting of the empirical model it turns out that persistence is strongly related to market...

This paper analyzes the impact of technological diversity on innovation inputs and success using Swiss firm-level panel data. While we do not find any impact of diversity on R&D intensity, we confirm a positive impact of diversity on patent applications as suggested by the literature. However,...

While recent literature has focused on explaining the determinants of green innovations, it is not well understood how such innovations affect performance. To analyse the relationship between green innovation and performance, new industry-level panel data were exploited: these include 12 OECD...

This paper investigates how the macroeconomic business cycle impacts the empirical relation between firms' innovations and their sales growth rates. Based on firm-level panel data over the time period 1995-2014, the paper finds no visible sales growth differentials between firms in booming...

This paper investigates the causal relationship between firms' research and development expenditures (R&D) and their investments into fixed capital. The literature provides two contrasting views in this respect. The first view holds that a firm's research activity causes, via the creation of...

This paper investigates the causal effect of funding research and development (R&D) cooperation with public universities on the performance of firms. We use comprehensive firm-level panel data from Switzerland that spans from 2010 to 2022 and covers a broad set of variables including the...
