Abstract
This paper employs the green technology classification published by the Japan Patent Office to estimate the values of green and non-green innovations. By computing patent values based on stock price reactions to the announcement of patent issuance, this paper finds that, on average, green patents have higher values than non-green patents in the pooled sample. However, results from the matched sample indicate the presence of selection biases.
