Context matters: How existing sectors and competing technologies affect the prospects of the Swiss Bio-SNG innovation system 总被引:1,自引:0,他引:1

Emerging technological fields are affected by developments in their broader context. This article proposes a differentiation of context structures as a crucial step in the analysis of technological innovation systems. A thorough context analysis, so the argument, is essential for understanding the pace and direction of technology development and the prospects of an emerging technological innovation system. Empirical insights are provided for Bio-SNG, a technology in an early stage of development. The article discusses the conditions under which actors from different sectors (forestry, wood industry, and energy supply) may play a role in the emerging field. It is shown that Bio-SNG is likely to become a victim of the recent boom in wood-to-energy technologies that has favored investments in more mature but technologically inferior alternatives. The case provides lessons for policy making as it highlights how effective support schemes might foster a lock-in into technologies that are readily available. 相似文献

Pigouvian taxes are efficient — but unpopular among voters — and hence often politically infeasible. Earmarking of revenues has been widely reported to increase public support for taxes, but earmarking is generally not the most efficient use of the revenues. This trade-off between efficiency and political feasibility is the motivation for our primary research objective: to quantify the effect of earmarking on support for fuel tax rises. Our secondary research objective is to investigate why earmarking increases support. Using data from a representative sample of the Norwegian voter population (N = 1147), we estimate models of voter preferences for fuel taxes using logistic regression models. Our results show that, in the absence of earmarking, the majority of voters would like to reduce fuel taxes, but earmarking the revenues for environmental measures has a substantial effect on voter support for fuel tax increases, garnering a majority for increases of up to 15% above present levels. Further analysis indicates that a prime reason why earmarking for environmental measures is popular is that it increases the perceived environmental effectiveness of the tax, and hence its legitimacy as an environmental rather than a fiscal policy instrument. 相似文献

In this paper, we challenge the widespread notion that replacement level fertility is the most desirable level of fertility both for countries currently above and below this level. We discuss possible alternative criteria for choosing one fertility level over another. In accordance with earlier studies, we focus on age dependency as the sole criterion. But we do so by relaxing the strong assumption that all individuals of a given age are equal in terms of their economic contribution to society and introduce education as probably the most relevant observable source of population heterogeneity. Our criterion variable is the education-weighted support ratio and we perform thousands of alternative simulations for different constant levels of fertility, starting from empirically given populations. If education is assumed to present a cost at young age and results in higher productivity during working age, then for most countries the desirable long-term total fertility rate turns out to be well below replacement level. 相似文献

In this paper we examine the value implications of 192 M&A transactions in the fashion and leather accessories industry during the period from 1994 to 2009. Contrary to general cross-country evidence we find highly significant, positive abnormal returns to acquiring shareholders. Cross-sectional analysis further reveals that the key value drivers are diversifying fashion M&A transactions for smaller, profitable companies that reduce idiosyncratic risk whereas deals executed by large companies that act as frequent acquirers do not, on average, significantly enhance shareholder wealth. 相似文献

Members of organizations are often called upon to trust others and to reciprocate trust while at the same time competing for
bonuses or promotions. We suggest that competition affects trust not only within dyads including direct competitors, but also
between individuals who do not compete against each other. We test this idea in a trust game where trustors and trustees are
rewarded based either on their absolute performance or on how well they do relative to players from other dyads. In Experiment
1, we show that competition among trustors significantly increases trust. Competition among trustees decreases trustworthiness,
but trustors do not anticipate this effect. In Experiment 2, we additionally show that the increase in trust under competition
is caused by a combination of increased risk taking and lower sensitivity to non-financial concerns specific to trust interactions.
Our results suggest that tournament incentives might have a “blinding effect” on considerations such as betrayal and inequality
aversion. 相似文献

In the last two decades, many U.S. states introduced policies to promote electricity generation from renewable energy sources (RES‐E). Renewable portfolio standards (RPS) are considered to be the key RES‐E policy tool to date. This article tackles the question on why some state legislators were front‐running the trend of RPS implementation whereas others adopted policies just recently, and why others have not adopted them at all. We compile data on financial contributions of conventional energy interest groups (CEI) and renewable energy interest groups (REI) to state‐level policy‐makers between 1998 and 2010. By means of hazard and tobit regressions, we test the effect of these financial contributions on the probability of RPS adoption and on RPS stringency. The article provides evidence in favor of interest group theory. First, CEI have donated more to state‐level legislators affiliated with the Republican Party than to Democrats while contributions from REI went largely to the latter. Second, there are statistically significant links between the likelihood of RPS adoption and private interest contributions. Contributions from CEI have a negative effect on the likelihood of RPS adoption whereas REI contributions have a positive effect. 相似文献
