The innovation trajectory of eco-cement in the Netherlands: a co-evolution analysis

In this article, we scrutinize the innovation trajectory of eco-cement in the Netherlands by examining the innovation nexus of eco-cement manufacturers, scientists/researchers, waste producers and policymakers as part of a broader analysis of markets, policy and society, with special attention to standards and regulations. The influence of policy and innovation interactions are substantiated by policy documents, media news, patterns of eco-cement use, and in-depth interviews conducted with relevant eco-cement actors. Our analysis brings forward empirical evidence of how policymakers are involved in the innovation trajectory of eco-cement in multiple ways through building regulations, sector policies, waste policies, and science and innovation policies. Political economy aspects of regulation and innovation in cement industry (e.g. the cooperative approach of waste authorities with regard to re-use of waste, absence of policies to put a price on CO₂ emissions from cement production) are being described, together with the specificities of the cement market. Bans on the disposal of fly ash and sewage sludge resulted in the use of those materials either as a supplementary cementitious material or a fuel. Demand for green cement from is presently growing but meets with several obstacles. Carbon policies are shown to constitute a weak influence. Innovation in eco-cement co-evolved with policy, through mutual dependencies, as a theoretical finding for innovation studies.     

Growth with Unused Capacity and Endogenous Capital Depreciation

The paper contributes to the debate on growth and distribution in a non‐mainstream perspective. It looks at the role that capacity utilization plays in the process of growth under the hypothesis that the rate of capital depreciation is a function of the degree of capacity utilization. Our hypothesis implies results partly different from those obtained by other models in which capacity utilization plays a key role. In particular, a varying rate of depreciation affects the conditions under which distributional changes in favor of wages affect the rate of growth positively.     

Organic as a Heuristic Cue: What Spanish Consumers Mean by Organic Foods

One of the strategies employed by companies to differentiate themselves from others, in the food market, has been to market organic products according to the assumption that environmental values are an important influence on people's behavior. However, studies of the behavior of organic food consumers show that there is some debate on this subject. Although some studies associate organic food consumption with motives and attitudes in which the environment plays a predominant role, a greater number conclude that the motives for consuming this type of food are basically egoistic (related to health, food safety, or the quality or flavor of the food). This can lead to problems in deciding the central thrust of the marketing strategy. The purpose of this paper is to analyze the meaning and interpretations placed on the term “organic,” and how they are integrated, as a way to explain consumption behavior. Qualitative research methods were adopted for this purpose. Four focus group sessions with different sociodemographic profiles, held in the cities of Madrid and Seville, in Spain, displayed two evident paradoxes, which could indicate that environmental motives are not important for consumers in this market. It is concluded that the term “organic” plays an important role as a heuristic cue to superiority, irrespective of the consumer's knowledge about the real features of organic food. Three alternative models are presented to explain consumer behavior. These results could be useful to food companies, largely in connection with positioning this type of product and with their communications policy.     

IFRS framework-based case study: DaimlerChrysler – Adopting IFRS accounting policies

This instructional case applies a framework-based approach to explore the concept of comparability in financial reporting and retrospective application of new accounting policies. The DaimlerChrysler (DC) case provides an opportunity for you to research key financial reporting concepts, analyze accounting policy differences between U.S. GAAP and IFRS, determine adjustments necessary to convert financial statements from U.S. GAAP to IFRS, and compute and discuss key ratio impacts following financial statement conversion. This case demonstrates that transitioning to IFRS is more than an accounting issue; it provides opportunities for financial restructuring (e.g., Daimler’s amendments to pension plans and its 2007 sale of Chrysler). It also illustrates the importance of professional judgment when initially adopting IFRS accounting policies. Also, despite FASB and IASB convergence efforts, you learn that most of the key differences between U.S. GAAP and IFRS identified in DC’s reconciliations continue today. This case helps you to: (1) develop skills to interpret and apply the requirements on first-time adoption of IFRS to a real-world setting; (2) research key differences between U.S. GAAP and IFRS and their effects on the financial statements and ratios; and (3) understand significant impacts of the transition to IFRS on businesses and financial statements. Completing the case develops your critical thinking and research/technological skills.     

Exploring the (un-) usefulness of mandatory assessment documents in primary technology

Every student in the Swedish compulsory school system is entitled to information regarding their progress in all school subjects given. In 2008, a mandatory assessment tool, called the individual development plan (IDP) with written assessment, was introduced by the Government. The statutory purpose was to provide teachers with a formative assessment tool to be used mandatory in the follow-up of student’s progress all thru mandatory compulsory school (year 1–9). This study explores the use of the IDP documents in technology education. Authentic documents from different municipalities, different schools and different school years have been studied. In this article findings regarding formal assessment documents and teacher’s formal assessment practice in primary (year 1–6) technology education are presented.     

Forecast combination through dimension reduction techniques

This paper considers several methods of producing a single forecast from several individual ones. We compare “standard” but hard to beat combination schemes (such as the average of forecasts at each period, or consensus forecast and OLS-based combination schemes) with more sophisticated alternatives that involve dimension reduction techniques. Specifically, we consider principal components, dynamic factor models, partial least squares and sliced inverse regression.Our source of forecasts is the Survey of Professional Forecasters, which provides forecasts for the main US macroeconomic aggregates. The forecasting results show that partial least squares, principal component regression and factor analysis have similar performances (better than the usual benchmark models), but sliced inverse regression shows an extreme behavior (performs either very well or very poorly).     

The age-productivity gradient: Evidence from a sample of F1 drivers

Estimating the effect of aging on productivity requires clean measures of productivity. Additionally, one needs to control for unobserved heterogeneity at the worker, firm and worker/firm level, to account for the role of experience and to correct for selection bias. We tackle these issues exploiting a panel of Gran Prix Formula One drivers, which provides a unique setting to single out the data requirements needed to credibly estimate the effect of age on productivity. Results robust to the inclusion of worker, firm and match effects show that the age-productivity link has an inverted U-shape profile with a peak at the age of 30-32. The use of repeated cross-sections of individuals also produces consistent results provided that cohort effects are properly accounted for. Relying on team-average measures of productivity makes instead inference harder.     

Conflicting tasks and moral hazard: Theory and experimental evidence

We study a multi-task principal-agent problem in which tasks can be in direct conflict with each other. In theory, it is difficult to induce a single agent to exert efforts in two conflicting tasks, because effort in one task decreases the success probability of the other task. We have conducted an experiment in which we find strong support for the relevance of this incentive problem. In the presence of conflict, subjects choose two efforts significantly less often when both tasks are assigned to a single agent than when there are two agents each in charge of one task.     

Outrunning the gender gap—boys and girls compete equally

Recent studies find that women are less competitive than men. This gender difference in competitiveness has been suggested as one possible explanation for why men occupy the majority of top positions in many sectors. In this study we explore competitiveness in children, with the premise that both context and gendered stereotypes regarding the task at hand may influence competitive behavior. A related field experiment on Israeli children shows that only boys react to competition by running faster when competing in a race. We here test if there is a gender gap in running among 7–10 year old Swedish children. We also introduce two female sports, skipping rope and dancing, to see if competitiveness is task dependent. We find no gender difference in reaction to competition in any task; boys and girls compete equally. Studies in different environments with different types of tasks are thus important in order to make generalizable claims about gender differences in competitiveness.
