This article seeks to show how a sectoral system approach may contribute to the analysis of the determinants of environmental innovations. By using Malerba's [F. Malerba: Sectoral systems of innovation and production, Res. Policy Vol. 102, 845-859, (2002)] concept of sectoral system of innovation and production, we develop a sectoral framework based on three building blocks: technological regimes, demand conditions and environmental and innovation policy. Within this framework, the sectoral patterns of environmental innovation result from the interplay between these three blocks. The conceptual framework is applied to the case of the French automotive industry, with a specific focus on the development of low emission vehicles. The analysis shows how technological regime and demand conditions lead to technological inertia, and so to a strong persistence of the dominant design. Finally, environmental and innovative policy are considered in an integrated way, so that we can study how they influence technological regime and demand conditions, and in the meantime how they are conditioned by these two blocks.  相似文献

The dynamics of US Treasury prices may be interrupted by jumps, and cojumps — where these occur simultaneously across the term structure. This paper finds significant evidence of jumps and cojumps in the US term structure using the Cantor-Fitzgerald tick dataset sampled over the period 2002–2006. While cojumping is frequently found in response to scheduled macroeconomic news announcement, around one-fifth of cojumps occur independently of news. The results are discussed in relation to term structure theories, day of the week effects, asymmetric news effects and trading volume.  相似文献

Prior research has demonstrated that consumers who take an opportunity and are satisfied (satisfied takers) are likely to avail of a future opportunity when it is presented again but those who forsake an opportunity and experience regret (regretful forsakers) are less likely to do so, exhibiting inaction inertia. In this research we demonstrate when and why regret for inaction may result in the intent to avail of a future opportunity and compare this intent with that of satisfied consumers. Specifically, we demonstrate in two studies that (1) when consumers forgo an opportunity and experience regret, they are motivated to avail of a similar opportunity when it is presented in the future, and (2) this intent by regretful forsakers may be more intense than that experienced by satisfied customers due to the elicitation of mental imagery regarding the anticipated consumption episode. All authors contributed equally to this paper.  相似文献

Integrated pest management (IPM) potentially reduces pesticide use and costs of agricultural production. However, IPM is knowledge intensive and its spread may dissipate over time due to knowledge required for its effective implementation and to competing messages about pest control. We examine IPM spread and adoption several years after formal intensive IPM outreach efforts ceased in a potato‐producing region in Ecuador. We describe adoption patterns and sources of IPM knowledge in 2012 and compare them with patterns that existed when outreach ceased in 2003. Results show that IPM adoption continues in the area but with a lower proportion of farmers fully adopting all practices and a higher proportion adopting low to moderate levels as compared to 2003. Almost all potato farmers in the area use some IPM practices, reflecting a major increase in IPM use. Farmer‐to‐farmer spread has supplanted formal training and outreach mechanisms. IPM adoption significantly lowers pesticide use and saves production costs for adopters.  相似文献

Management control in the workplace ultimately rests on the power to dismiss employees who are deemed to be underperforming. This article examines a more recent trend away from annual appraisal and towards continual monitoring and review. Based on a study of specialist proprietary performance management (PM) software packages and interviews with the consultants who market them, the contention is that these developments are driven by the need to control dismissal. In the case of the UK, we argue that the adoption of PM systems needs to be understood as a means of ‘retiring’ older workers who might otherwise remain in employment. The systems studied here draw on a range of data, allowing managers considerable discretion in how this evidence is used. Specifically, by dispensing with explicit ranking methods, these systems suggest a new employer confidence in the use of subjective evidence.  相似文献

From a Chinese perspective, chances of any change in the Yuan exchange rate look pretty slim. If you were an official in Beijing, would you stick your neck out even recommending this idea? If the status quo looks fairly acceptable, and it is ‘stability oriented’ (a very Chinese preference), why go rocking the boat? You certainly do not make any changes just because Japan or the US tell you to. And financial markets are not that persuasive – after all they wanted a devaluation only a short while ago. In this article, Vanessa Rossi and Simon Knapp assess the likelihood of a Yuan revaluation and its implications for the economic outlook.  相似文献

This paper presents a quarterly global model combining individual country vector error‐correcting models in which the domestic variables are related to the country‐specific foreign variables. The global VAR (GVAR) model is estimated for 26 countries, the euro area being treated as a single economy, over the period 1979–2003. It advances research in this area in a number of directions. In particular, it provides a theoretical framework where the GVAR is derived as an approximation to a global unobserved common factor model. Using average pair‐wise cross‐section error correlations, the GVAR approach is shown to be quite effective in dealing with the common factor interdependencies and international co‐movements of business cycles. It develops a sieve bootstrap procedure for simulation of the GVAR as a whole, which is then used in testing the structural stability of the parameters, and for establishing bootstrap confidence bounds for the impulse responses. Finally, in addition to generalized impulse responses, the current paper considers the use of the GVAR for ‘structural’ impulse response analysis with focus on external shocks for the euro area economy, particularly in response to shocks to the US.
