We estimate the determinants of various types of product innovation. Knowledge spillovers from rivals have a positive impact on incremental innovations. This impact is largely independent of the participation in R&D cooperations. Spillovers exert no such independent influence on drastic...

This paper studies the introduction of new products (increase in product variety) in the automobile industry. The focus is on the two sources of market power that may allow the firms to get higher profits (and, thus, recoup investments): new products and brand-name reputation. The effects of new...

The importance of understanding how consumers gather and evaluate information about the new products is essential for providers. This paper considers the student population as consumers and attempt to determine where students as consumers learn information about new products and their attitudes...

Nowcasting has been a challenge in the recent economic crisis. We introduce the Toll Index, a new monthly indicator for business cycle forecasting and demonstrate its relevance using German data. The index measures the monthly transportation activity performed by heavy transport vehicles across...

We analyze the effect of a labor market reform on firms' product innovation. The re- form, which amounts to a natural experiment, differentially reduced firing costs for some firms, thereby lowering adjustment costs in the presence of demand uncertainty. Using a difference-in- differences...

We consider an example of the impact of a new good on producers of close substitutes: the invention of margarine and its rapid introduction into the British market from the mid-1870s. This presented a challenge to the traditional suppliers of that market, butter producers from different European...

Satiation of need is generally ignored by growth theory. I study a model where consumers may be satiated in any given good but new goods may be introduced. A social planner will never elect a trajectory with long-run satiation. Instead, he will introduce enough new goods to avoid such a...

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,...

Mobile phones are increasingly used as a gateway to the Internet. The take-up of mobile phone-enabled Internet services was, however, initially slower than expected, at least in Europe. We estimate non-parametrically the price elasticities of demand for first-generation wireless services using...
