Urban and agricultural soils: conflicts and trade-offs in the optimization of ecosystem services

On-going human population growth and changing patterns of resource consumption are increasing global demand for ecosystem services, many of which are provided by soils. Some of these ecosystem services are linearly related to the surface area of pervious soil, whereas others show non-linear relationships, making ecosystem service optimization a complex task. As limited land availability creates conflicting demands among various types of land use, a central challenge is how to weigh these conflicting interests and how to achieve the best solutions possible from a perspective of sustainable societal development. These conflicting interests become most apparent in soils that are the most heavily used by humans for specific purposes: urban soils used for green spaces, housing, and other infrastructure and agricultural soils for producing food, fibres and biofuels. We argue that, despite their seemingly divergent uses of land, agricultural and urban soils share common features with regards to interactions between ecosystem services, and that the trade-offs associated with decision-making, while scale- and context-dependent, can be surprisingly similar between the two systems. We propose that the trade-offs within land use types and their soil-related ecosystems services are often disproportional, and quantifying these will enable ecologists and soil scientists to help policy makers optimizing management decisions when confronted with demands for multiple services under limited land availability.     

Strategizing in NPOs: A Case Study on the Practice of Organizational Change Between Social Mission and Economic Rationale

This article presents the main results of a longitudinal case study of a strategic change process in a cooperative bank. Pursuing both a “social” mission and an explicitly economic rationale, this particular nonprofit organization provides an exemplary research setting for inquiring into the delicate and contradictory interplay of mission focus and commercial imperatives. Departing from the practice perspective as a micro-view on everyday strategizing—an approach that seems to have not found its way into NPO-research yet—allows us to take an in-depth look at how people go about the process of making strategy despite the tensions between mission and profit. Our data yields three patterns of strategizing practices that aim at fostering economic growth without damaging the social mission, namely supporting diverse positions, protecting stabilized relationships, and relating to organizational experiences. Building upon our empirical results, we tentatively conceptualize “balancing practices” as potentially important acts of strategizing in NPOs.     

The Effect of a Family Policy Reform on Mother’s Pay: A Natural Experiment Approach

All parents in Norway with children aged one to three, who do not attend publicly subsidised day care, are entitled to a cash-for-care (CFC) subsidy. Studies have shown that the reform has reduced mothers labour supply. In this paper we analyse wage effects of the reform. We put forward a framework for evaluating reforms when reforms are uniformly and equally accessible nation-wide. First, running a simple Difference in differences (DD) analysis, results suggest that the CFC reform has reduced the mothers wages. However, after controlling for the age of the child effect, by running a triple difference approach, we no longer find any evidence of negative wage effects.This revised version was published online in May 2005 with corrections to the authors name and to the heading of table A2.     

Entwickeln im Team – Effekte für den Einzelnen

This study tested the effects of a 2-day team building intervention on team members’ team identification, social support and collective self-efficacy. Members (n?=?32) of three teams from different sectors completed questionnaires before, directly after and six weeks after the team building intervention. Two teams served as control groups. Results showed lasting positive effects of team building on identification, support and collective self-efficacy in the training groups but no changes in the control groups.     

The Gender Dimension of Social Policy Reform in Turkey: Towards Equal Citizenship?

This article discusses the current social policy reform process in Turkey from a gender perspective. Until now, social security and labour regulations have provided women with special benefits and protections. Depending on the particular case, these gender‐specific policies can be interpreted differently – as positive discrimination, satisfying practical gender interests, or as a reinforcement of traditional gender norms and relations, stigmatizing women as a weaker, vulnerable group in need of special protection. Ongoing reform initiatives, however, neutralize most of these long‐lasting gendered policies, either by terminating rights formerly enjoyed only by women or by extending these rights to men as well. The article questions this changing nature of social policy as to whether it promises equal citizenship for women or increases their vulnerability, in the absence of former benefits and without sufficient policy measures for improved capability.     

Entitlement and the efficiency-equality trade-off: an experimental study

When randomly assigning participants to experimental roles and the according payment prospects, participants seem to receive “manna from heaven.” In our view, this seriously questions the validity of laboratory findings. We depart from this by auctioning off player roles via the incentive compatible random price mechanism thus avoiding the selection effect of competitive second price auctions. Our experiment employs the generosity game where the proposer chooses the size of the pie, facing an exogenously given own agreement payoff, and the responder is the residual claimant. We find that entitlement crowds out equality seeking and strengthens efficiency seeking. More generally, we find that inducing entitlement for the roles in which participants find themselves makes a difference. Interpreting participants’ willingness to pay for their role as their aspiration level further allows to test satisficing and explore “mutual satisficing.” We find that responder participants apparently do not anticipate proposer generosity in aspiration formation.     

Incentive effects and the income tax treatment of employer-provided workplace benefits

Employers often provide their employees with different kinds of benefits in the workplace to create comfortable working conditions. In order to avoid distortions of the wage-benefit ratio in employee compensation, economic theory suggests that fringe benefits should be subject to income taxation at a value placed on them by employees. This article shows that this approach does not apply to workplace benefits. Since the goal of these benefits is to reduce the employees’ disutility from work, treating them simply as wage substitutes disregards their incentive effects. Therefore, the rules for taxing workplace benefits are derived from an agency model. It is shown that in contrast to the standard economic approach, cost can be a more efficient tax base than willingness to pay, even though this results in higher tax payments. Moreover, with non-distortionary tax rates it is always better to tax the employer rather than the employee.
