The main objective of this paper is to analyze the potential goal conflict between two of Sweden's environmental objectives: Sustainable Forests and Reduced Climate Impact – or, more precisely, the conflict between forest conservation and the supply of wood fuel. To accomplish this, we use a forest sector model that includes the suppliers and major users of roundwood. The econometric results, based on a data set that spans 40 years, show that all the own price elasticities have the expected signs. Among the three forestry products, the supply and (long-term) demand of forest fuel seems to be most sensitive to a price change. In a second step, the estimated model is used to simulate the effect of increased forest conservation – the Sustainable Forest objective – on the supply of wood fuel. If oil is used as a substitute, Swedish emissions of greenhouse gases will increase by almost 0.92 percent, which indicates a clear conflict with the Reduced Climate Impact objective.  相似文献

This note proposes a non‐parametric estimation method controlled for endogeneity to calculate poverty elasticities for a panel of countries. Results show that usual linear estimates without control for endogeneity overestimate the growth elasticity of poverty.  相似文献

In this paper we consider two important aspectsin the complex problem of transboundary airpollution in Europe, namely (i) theinterdependence of the problems of troposphericozone and acidification and (ii) the dynamicprocesses related to soil acidification. Wedevelop an optimal control model to analyse theinteraction between acidification as a stockpollutant and tropospheric ozone as a flowpollutant for several countries. Using acost-benefit framework an analysis is performedto determine efficient emission paths fornitrogen oxides, sulphur dioxide and volatileorganic compounds. The model jointly analysesacidification and ozone. The current Europeanreduction plans do not fully take into accountthe multi-pollutants multi-targets nature ofthe problem. In addition, the plans allow fortemporary exceedance of critical loads withoutconsidering the consequences for the temporaldevelopment of the soil quality. This papershows the complex relations and interactionswhich one should deal with while designingpolicies that are efficient with respect to thecross-effects between the differentenvironmental problems. It also shows howdynamic efficient abatement strategies wouldlook if the cross effects and the dynamicprocesses in soil acidification are explicitlyincorporated in the analysis.  相似文献

We propose a new empirical specification of volatility that links volatility to the information flow, measured as the order flow in the market, and to the price sensitivity to that information. The time-varying market sensitivity to information is estimated from high-frequency data, and movements in volatility can therefore be directly related to movements in order flow and market sensitivity. Empirically, the model explains a large share of the long-run variation in volatility. Importantly, the time variation in the market's sensitivity to information is at least as relevant in explaining the persistence of volatility as the rate of information arrival itself. This may be evidence of a link between changes over time in the aggregate behavior of market participants and the time-series properties of realized volatility.  相似文献

When firms launch a new product into the marketplace they often aim to find a balance between building scale and provoking extensive and quick competitive reactions. Competitors react to new products when they perceive the product introduction as hostile, committed or when they feel that the product entry will have a large impact on their profitability. The present study develops a framework that shows how strong and fast incumbents react to perceived market signals resulting from a new product's launch decisions (broad targeting, penetration pricing, advertising intensity and product advantage). The strength of the relationships between the launch decisions and the perceived market signals was expected to depend on one industry characteristic (i.e., market growth) and on one entrant characteristic (i.e., aggressive reputation). We distinguished three market signals in our framework: hostility, commitment and consequences. Signal hostility refers to the extent to which the approach used by an acting firm to introduce the new product is perceived hostile whereas the commitment signal refers to the extent to which incumbents perceive the entrant firm to be committed to the new product introduction. The consequence signal is defined as the incumbents' perception of the impact of a new product entry on their profitability. We tested our framework using cross‐sectional data provided by 73 managers in The Netherlands who recently reacted to a new product entry. The results clearly reveal which launch decisions create which market signals. For example, incumbents consider high advantage new products hostile and consequential. Penetration pricing and an intense advertising campaign are also considered hostile, especially in fast growing markets. Broad targeting is not perceived hostile, especially not when used by entrants with an aggressive reputation. In addition, this study explored the impact of three perceived market signals on the strength and speed of competitive reaction. The results reveal that perceived signals of hostility and commitment positively impact the strength of reaction, whereas the perceived consequence signal positively impacts the speed of reaction. The article concludes with the implications of our study for managers and academics. The relevance to managers was assessed from both the perspective of the incumbent firm that must defend, and that of the rival firm that is introducing the new product.  相似文献

Cartographic roadmaps used for navigating from A to B provide a strong metaphor for innovation roadmaps used at firms for navigating from the present to the future. Now ready to move beyond this metaphor—the pace and proliferation of knowledge on innovation roadmapping have reached a point at which it would be useful to lay out some groundwork for extended theorizing and research in this area. This paper contributes here by reporting on a qualitative inductive research based on documented practitioners’ insights. To better understand the phenomenon of innovation roadmapping (what it is and what it is not) and its impact on innovation performance, this study builds concepts in the context of strategic innovation management theory. Through a systematic analysis of the qualitative data extracted from 12 cases selected from the extant literature, this research found five concepts with common ground in these cases and built a framework in which innovation roadmapping is established by (1) a strategy of time pacing, (2) synchronizing dialogues, and (3) mapping innovation elements to a timeline. Furthermore, the systematic analysis of the documented practitioners’ insights indicates that roadmapping affects either the innovation performance of (4) competitive timing or (5) industry synergy. Overall, this leads to an initial formulation of theory with this conceptual framework and six related propositions. The key insights for innovation managers in industrial firms are that, in striving for competitive timing or industry synergy, roadmapping provides a means to achieve these objectives and, in deploying roadmapping in the organization, dialogue and pacing are critically important.  相似文献
