By assigning rights and conditions of use, spectrum policy regulates how radio frequencies can be used by mobile networks. We develop a parameterised calculator tool to estimate the impact of various spectrum policy aspects on the emissions of the mobile sector. We model the impacts during the...

We investigate the dynamics of voluntary cooperation to either reduce the size or the probability of stochastic losses. For variants of a repeated four person prisoner’s dilemma game, we show that cooperation is larger and more stable when it affects the probability rather than the size of the...

Based on unique data from representative computer-based surveys among more than 3400 citizens, this paper empirically examines the determinants of climate change beliefs, climate policy support, and climate protection activities in three countries which are key players in international climate...

The results in this paper show that a policy maker who ignores regional data and instead relies on aggregated integrated assessment models will strongly underestimate the carbon price and thus the required climate policy. Using a stylized theoretical model we show that, under the mild and...

When politicians negotiate in international climate conventions they may suffer from incomplete information about each other's preferences about reaching an agreement. As is known, this may cause failure to reach an efficient cooperative agreement. We study the role of the clean development...

Economic measures are advanced to environmental problems in EU nations. The economic approach imposes a constant economic load on activities negatively affecting the environment, and it is also a technique for giving a constant profit for activities conserving the environment. The whole society...

This paper discusses the developments in the markets for CO2 emissions rights since the Kyoto Protocol has been signed. The different emission trading schemes dominated by the ETS of the European Union and the Clean Development mechanism are surveyed. These schemes will need to be incorporated...

To analyze the effect of unilaterally tightened climate policies, we augment the two country model of Hoel (2011) with fossil fuel extraction costs. It turns out that a tighter climate policy of the country with the initially stricter policy causes neither a weak nor a strong green paradox if...

Cities, home to more than half of the world's population and important economic hubs, are vulnerable to impacts of climate change and worthy to protect. To address these challenges, implementing climate change adaptation measures is inevitable. The paper provides insights into climate change...
