Public organizations involved in marine management are increasingly confronted with coordination challenges in marine governance. This study examines why and how the Norwegian Institute of Marine Research (IMR) reorganized its formal coordination structures between the areas of fisheries management and marine environmental management The findings indicate that organizing efficient and, at the same time, legitimate coordination structures between different areas of marine governance is a "wicked" organizational problem with no ultimate and single optimal solution. In contrast to the assumptions of classical organization and management theory, the study finds that the reorganization of formal coordination structures is not necessarily driven for reasons of efficiency and perceived coordination problems. Instead, public marine management organizations also change their organizational structures to live up to external expectations to adopt modern management concepts, such as the Ecosystem Approach to Management (EAM). However, the study indicates that the adoption of the EAM has stimulated coordination and integration efforts in the research and advisory activities of the IMR. (C) 2015 Elsevier Ltd.

Many countries support business start-ups to spur economic growth and reduce unemployment with different programmes. Evaluation studies of such programmes commonly rely on the conditional independence assumption (CIA), allowing a causal interpretation of the results only if all relevant variables affecting participation and success are accounted for. While the entrepreneurship literature has emphasised the important role of personality traits as predictors for start-up decisions and business success, these variables were neglected in evaluation studies so far due to data limitations. In this paper, we evaluate a new start-up subsidy for unemployed individuals in Germany using propensity score matching under the CIA. Having access to rich administrative-survey data allows us to incorporate usually unobserved personality measures in the evaluation and investigate their impact on the estimated effects. We find strong positive effects on labour market reintegration and earned income for the new programme. Most importantly, results including and excluding individuals׳ personalities do not differ significantly, implying that concerns about potential overestimation of programme effects in the absence of personality measures might be less justified if the set of other control variables is rich enough.
I examine the determinants of both perceived inflation and unemployment in one single survey and include Big Five traits in the analysis. This is the first survey on this topic in Germany. My sample consists of 1771 students from different fields and levels. Using PhD students’ estimates as a reference, I create categories for underestimation and overestimation of both variables. Multinomial logit regressions show that females overestimate both variables. Education and news consumption reduce misestimation. A higher level of Neuroticism is related with a higher probability to overestimate unemployment. Overstating (understating) one indicator is associated with overstating (understating) the other.
Ramsey meets Thünen

Land taxes can increase production in the manufacturing sector and enhance land conservation at the same time, which can lead to overall macroeconomic growth. Existing research emphasizes the non-distorting properties of land taxes (when fixed factors are taxed) as well as growth-enhancing impacts (when asset portfolios are shifted to reproducible capital). This paper furthers the neoclassical perspective on land taxes by endogenizing land allocation decisions in a multi-sector growth model. Based on von Thünen’s observation, agricultural land is created from wilderness through conversion and cultivation, both of which are associated with costs. In the steady state of our general equilibrium model, land taxes not only may reduce land consumption (associated with environmental benefits) but may also affect overall economic output, while leaving wages and interest rates unaffected. When labor productivity is higher in the manufacturing than in the agricultural sector and agricultural and manufactured goods are substitutes (or the economy is open to world trade), land taxes increase aggregate economic output. There is a complex interplay of conservation policy, technological change and land taxes, depending on consumer preferences, sectoral labor productivities and openness-to-trade. Our model introduces a new perspective on land taxes in current policy debates on development, tax reforms as well as forest conservation.
Situated at the intersection of the literatures on speculative storage and non-renewable commodity scarcity, this paper considers whether changes in persistence have occurred in long-run U.S. prices of the energy commodities crude oil, natural gas and bituminous coal. We allow for a structural break when testing for a break in persistence to avoid a change in the stochastic properties of prices being confounded by an unaccounted-for deterministic shift in the price series. We find that coal prices are trend stationary throughout their evolution and that oil prices change from stationarity to non-stationarity in the decade between the late 1960s to late 1970s. The result on gas prices is ambiguous. Our results demonstrate the importance of accounting for a possible structural shift when testing for breaks in persistence, while being robust to the exact date of the structural break. Based on our analysis we caution against viewing long-run energy commodity prices as being non-stationary and conclude in favor of modeling commodity market fundamentals as stationary, meaning that speculative storage will tend to have a dampening effect on prices. We also cannot reject that long-run prices of coal and, with some hesitation, gas follow a Hotelling-type rule. In contrast, we reject the Hotelling rule for oil prices since the late 1960s/early 1970s. (C) 2016 Elsevier B.V. All rights reserved.
The 2008-2010 food crisis might have been a harbinger of fundamental climate-induced food crises with geopolitical implications. Heat-wave-induced yield losses in Russia and resulting export restrictions led to increases in market prices for wheat across the Middle East, likely contributing to the Arab Spring. With ongoing climate change, temperatures and temperature variability will rise, leading to higher uncertainty in yields for major nutritional crops. Here we investigate which countries are most vulnerable to teleconnected supply-shocks, i.e. where diets strongly rely on the import of wheat, maize, or rice, and where a large share of the population is living in poverty. We find that the Middle East is most sensitive to teleconnected supply shocks in wheat, Central America to supply shocks in maize, and Western Africa to supply shocks in rice. Weighing with poverty levels, Sub-Saharan Africa is most affected. Altogether, a simultaneous 10% reduction in exports of wheat, rice, and maize would reduce caloric intake of 55 million people living in poverty by about 5%. Export bans in major producing regions would put up to 200 million people below the poverty line at risk, 90% of which live in Sub-Saharan Africa. Our results suggest that a region-specific combination of national increases in agricultural productivity and diversification of trade partners and diets can effectively decrease future food security risks.
Since spring 2014 the relations between the EU and Russia are stuck in an Ice Age. From a Western point of view, especially the annexation of Crimea by Russia and the intervention in the conflict in Ukraine are responsible. The EU has frozen their relations to Russia and applied sanctions against it. Russia reacted in the same way. Can this vicious circle be broken without betraying the values of the EU? This book presents the analysis and ideas of social scientists from Germany, Poland and Russia. The reasons for this crisis are seen quite differently but all try to find a way out of the current confrontation.
We analyze the link between R&D, innovation, and productivity in MSMEs with a special focus on micro firms with fewer than 10 employees; usually constituting the majority of firms in industrialized economies. Using the German KfW SME-panel, we examine to what extent micro firms are different from other firms in terms of innovativeness. We find that while firms engage in innovative activities with smaller probability, the smaller they are, for those firms that do make such investment, R&D intensity is larger the smaller firms are. For all MSMEs, the predicted R&D intensity is positively correlated with the probability of reporting innovation, with a larger effect size for product than for process innovations. Moreover, micro firms benefit in a comparable way from innovation processes as larger firms, as they are similarly able to increase their labor productivity. Overall, the link between R&D, innovation, and productivity in micro firms does not largely differ from their larger counterparts. (C) 2016 Elsevier B.V. All rights reserved.
Buyer-seller negotiations have significant impact on a company’s profitability, which makes practitioners aim at maximizing their performance. One lever for increasing bargaining performance is to pursue a clearly defined aspiration, i.e. one’s most desired outcome. In this context, the author explores the role of such aspirations in the three negotiation phases: preparation, bargaining, and striking a deal. She investigates determinants of aspirations, unintended consequences such as unethical bargaining behavior, and the consequences of overly ambitious aspirations. As a result, she does not only close existing gaps in negotiation research, but also derives valuable implications for practitioners
This article is a response to calls in prior research that we need more longitudinal analyses to better understand the foundations of PSM and related prosocial values. There is wide agreement that it is crucial for theory building but also for tailoring hiring practices and human resource development programs to sort out whether PSM-related values are stable or developable. The article summarizes existent theoretical expectations, which turn out to be partially conflicting, and tests them against multiple waves of data from the German Socio-Economic Panel Study which covers a time period of 16 years. It finds that PSM-related values of public employees are stable rather than dynamic but tend to increase with age and decrease with organizational membership. The article also examines cohort effects, which have been neglected in prior work, and finds moderate evidence that there are differences between those born during the Second World War and later generations.

This article introduces the concept of sustainability-rooted anticonsumption (SRAC), which refers to consumers' anticonsumption practices of voluntary simplicity in living and, on a smaller level, collaborative consumption and boycotting with the goal of supporting sustainable economic development. The SRAC measurement approach is validated based on three empirical studies. Results of a representative German sample (Study 2) reveal that SRAC is predominantly negatively linked to consumer overconsumption dispositions. Exemplary, voluntary simplification and boycott intention may result in declining levels of indebtedness. Study 3 shows that psychosocial well-being is positively related to SRAC and overconsumption. However, a simplified lifestyle and a greater willingness to boycott are not necessarily associated with psychosocial well-being. This article provides insights for practitioners and policymakers to leverage existing SRAC values via “new” business models (sharing offers) or to influence the existing level of consciousness to effectively pave the way for solid progress in the sustainability movement.
The positive aspects of open innovation projects are widely discussed in innovation management research and practice by means of case studies and best practices. However, enterprises, particularly small and medium-sized enterprises (SMEs) also face miscellaneous challenges in open innovation practice, leading to uncertainty and even renunciation of open innovation project participation. Thus, it is essential for SMEs to find the right balance between possible positive effects and negative consequences - the latter being the less studied "dark sides" of open innovation. However, appropriate methods of finding this balance are still lacking. In this article, we discuss the assessment of open innovation project participation by presenting a weighing and decision process framework as a conceivable solution approach. The framework includes an internal, external, and integrated analysis as well as a recommendation and decision phase. Piece by piece, we investigate the current situation and the innovation goals of the enterprise as an initial point for a decision for or against engaging in open innovation. Furthermore, we discuss the development of a software tool that automatically applies this framework and allows self-assessment by SMEs.
This paper studies the effectiveness of building height limits as a policy to limit greenhouse gas (GHG) emissions. It shows that building height limits lead to urban sprawl and higher emissions from commuting. On the other hand, aggregate housing consumption may decrease, which reduces emissions from residential energy use. A numerical model is used to evaluate whether total GHG emissions may be lower under building height restrictions. Welfare is not concave in the strictness of building height limits, so either no limit or a very strict one (depending on the strength of the externality) might maximize welfare. The paper discusses several extensions, such as congestion, endogenous transport mode choice, migration, and urban heat island effect. (C) 2016 Elsevier B.V. All rights reserved
