This paper provides new evidence on the objectives and determinants of different typesof innovations and patents, environmental as opposed to other innovations and patents,and different variants of environmental innovations and patents. We investigate howfirm-specific and sector-specific driving...

This thesis studies the interaction between new and used durable goods without physical depreciation. In product categories such as CDs/DVDs and video games, the competition from used goods markets has been viewed as a serious problem by producers. These products physically depreciate...

Empirical analyses of the determinants of environmental innovations were rarely able to distinguish between different areas of environmental impacts. The paper tries to close this gap by employing a new and unique dataset based on the German Community Innovation Survey conducted in 2009. The...

Estimating structural models is often viewed as computationally difficult, an impression partly due to a focus on the nested fixed-point (NFXP) approach. We propose a new constrained optimization approach for structural estimation. We show that our approach and the NFXP algorithm solve the same...

Disagreement among researchers regarding types of optimal choice experiments is often best seen as resulting from differences in the set of assumptions researchers are willing to make about the underlying data generating process. Much of the current debate may have confused, rather than...
