Exploring the interaction of firm-level change and national institutional environments in shaping employment and union relations: a comparative case study of four European airlines

Drawing on the example of the airline industry, this paper explores in a longitudinal comparative case study the question of how firm-level changes and national institutional environments interact in shaping employee and union relations. Adding to previous research in comparative institutional analysis and comparative employment relations, we illustrate that the way in which industry pressures and national-level effects play out to influence employee and union relations depends on firm-level changes, mainly in the form of firm growth, acquisitions and the foundation of new subsidiaries. We show in particular that depending on firm-level changes, the very same firm might engage differently with a given institutional context at different points in time. Hence, our work illustrates the importance of firm growth, acquisitions and the foundation of new subsidiaries in explaining the shifting interaction between the firm and its institutional environment, and its implications for changing employee and union relations within firms.     

Integrating a virtual learning environment into a second-year accounting course: determinants of overall student perception

Rapid acceptance of, and changes in, information technology are revolutionizing the way educators teach and students learn. This study reports on the use of Blackboard as a tool for creating a virtual learning environment (VLE). Responses from undergraduate accounting students in New Zealand provide data on the use of the VLE as a learning aid. Findings suggest that the students have openly embraced the VLE and support its adoption by faculty members in other courses. However, students appear unwilling to actively participate in two-way online activities. This has implications for faculty contemplating the adoption of a VLE in their courses.     

The Impact of Equity-preferences on the Stability of International Environmental Agreements

This paper uses a coalition formation model to explore how equity considerations affect countries’ cooperation on global environmental issues, e.g. on climate change. When developing countries are exempted from obligations to reduce their emissions, I find that opening them for abatement projects financed by industrialized countries changes the incentives to cooperate in a way which can increase emissions and decrease welfare. Equity- concerns in industrialized countries regarding the difference between their per capita emission levels and those of developing countries lead to increased abatement but do not qualitatively change the incentives to cooperate. Inequality-aversion with respect to differences to abatement targets across industrialized countries generally induces larger coalition sizes and stricter abatement. Here, the inclusion of developing countries improves upon the prospects of cooperation.     

Climate Change and the Irreversibility Effect – Combining Expected Utility and MaxiMin

This paper analyzes decisions on emissions of a stock pollutant under uncertaintyin a two period model. Decisions are based on a weighted average of expected utility (EU) and the MaxiMin criterion. I first show that more weight on the worst case (less weight on EU) may lead to increased first period emissions. The effect of learning possibilities on emissions is not clear in general, but depends qualitatively on the weight given to MaxiMin: For the quadratic utility case, considering prospective learning increases today's abatement effort, i.e. the irreversibility effect holds, if the weight on EU is small. This contrasts standard results on the irreversibility effect for EU which translates to small weights on MaxiMin. There is, however, the possibility of a negative value of learning. It is shown that the irreversibility effect holds if and only if thevalue of learning is negative. Consequences for the applicability of generalized EU-MaxiMin are discussed.     

Beyond GDP: Towards a Green Economy Index

Given the broad (economic, social and environmental) objectives of a green economy, and the limitations associated with mainstream measures of economic performance (such as gross domestic product), an alternative or expanded set of indicators is required for measuring progress toward a green economy. This article develops a composite index for measuring green economic performance, based on 26 indicators across the economic, social and environmental dimensions. The index will enable comparison of a country's green economic performance both over time and relative to other countries. Furthermore, the index is constructed in such a way as to allow for disaggregation (i.e. for scores on individual components to be seen at a glance), such that areas of specific concern can be easily identified and addressed, and progress in each area monitored over time. The index was tested on data from 193 countries, and the resulting country rankings were assessed.     

(Un)fair Delegation: Exploring the Strategic Use of Equity Rules in International Climate Negotiations

We provide a new approach for identifying a strategic use of equity arguments in international (climate) negotiations. We first develop a theoretical model of strategic delegation which accounts for both environmental as well as equity preferences. We show that the strategic use of equity arguments qualitatively depends on the extent to which environmental preferences can be misrepresented: representatives from different countries may be expected to have similar equity views rather than widely differing perceptions of a fair share. Based on survey data on climate negotiations, we then provide empirical evidence for differences between equity preferences of citizens from Germany, China, and the U.S. and the perceived view on the position of their respective countries.     

Forecasting financial market volatility: Sample frequency vis-à-vis forecast horizon

This paper explores the return volatility predictability inherent in high-frequency speculative returns. Our analysis focuses on a refinement of the more traditional volatility measures, the integrated volatility, which links the notion of volatility more directly to the return variance over the relevant horizon. In our empirical analysis of the foreign exchange market the integrated volatility is conveniently approximated by a cumulative sum of the squared intraday returns. Forecast horizons ranging from short intraday to 1-month intervals are investigated. We document that standard volatility models generally provide good forecasts of this economically relevant volatility measure. Moreover, the use of high-frequency returns significantly improves the longer run interdaily volatility forecasts, both in theory and practice. The results are thus directly relevant for general research methodology as well as industry applications.     

Education policy and tax competition with imperfect student and labor mobility

This paper analyzes the effect of increasing human-capital mobility—i.e. student and labor mobility—on net tax revenues when revenue-maximizing governments compete for human capital by means of income tax rates and amenities offered to students (positive expenditure) or rather tuition fees (negative expenditure). An increase in labor mobility implies neither an intensified tax competition nor an erosion of revenues. In fact, the equilibrium tax rate even increases in labor mobility. Amenities offered to students are non-monotonically related to labor mobility; overall, net revenues increase with labor mobility. An increase in student mobility, however, erodes revenues, mainly due to intensified tax competition. A concurrent cutback in expenditures mitigates this erosion but cannot fully prevent it.
