Both climate change and technical change are uncertain. In this paper we show the importance of including both uncertainties when modeling for policy analysis. We then develop an approach for incorporating uncertainty of technical change into climate change policy analysis. We define and demonstrate a protocol for bottom-up expert assessments about prospects for technologies. We then describe a...

This paper considers the effect of different firm leadership on the innovative performance of firms from seven EU countries. We investigate whether owner-led or manager-led firms achieve a larger share of their turnover with product innovations. Economic theory does not propose clear answers to this question. In the empirical analysis, it turns out that the manager-led firms are more active inn...

Within the recent literature studying participation in international markets using micro data, a small number have suggested that firms benefit from their exposure to international markets. One channel considered for this role has been investments in R&D. A common finding in this literature is that firms involved in international trade are also more likely to also undertake R&D. In this paper w...

This paper compares the geographic “reach” of knowledge flows from university inventions through two important channels: market contracts (licenses) and non–market “spillovers” exemplified by patent citations. We find that knowledge flows through market transactions to be more geographically localized than those operating through non–market spillovers. Moreover, the differential effects of dist...

Focusing on the electronics industry, this paper verifies and compares how bipolar R&D policy contributed to growth in productivity in Korea and Taiwan. Two implications are derived from the empirical results. First, in Korea, government’s business group-centered R&D policy encouraged private R&D expenditure rather than public R&D infrastructure. Second, and in contrast, publicly funded R&D inf...

a simple, sensitive, accurate and precise simultaneous uv spectrophotometric method has been developed for the estimation of carisoprodol, paracetamol and caffeine in tablet dosage form. the absorption maxima of the drugs were found to be 221, 248 and 273 nm for carisoprodol, paracetamol and caffeine respectively, in methanol, using a double beam uv/visible spectrophotometer. carisoprodol, para...

The literature on R&D contests implicitly assumes that contestants submit their innovation regardless of its value. This ignores a potential adverse selection problem. The present paper analyzes the procurement of innovations when the procurer cannot commit to never bargain with innovators who bypass the contest. We compare fixed-prize tournaments with and without entry fees, and optimal scorin...

When effort is multi-dimensional, firms will optimally “balance” the provision of incentives. Setting high-powered incentives along one dimension raises the returns to providing high-powered incentives along other dimensions which compete for the worker’s effort and/or attention (Holmstrom and Milgrom, 1991). We test for this effect in the context of for-profit pharmaceutical laboratories using...

Despite mounting evidence on the potential benefits of inbound open innovation, little is known about how firms purposefully manage inflows of knowledge. We investigate the use of two knowledge governance procedures—project management and knowledge matching—in collaborative inbound open innovation. Our findings suggest that, in addition to “knowledge-precursors,” which the literature on open in...
