In this paper we empirically compare the transaction costs from monitoring, reporting and verification (MRV) of two environmental regulations directed to cost-efficiently reduce greenhouse gas emissions: a carbon dioxide (CO2) tax and a tradable emissions system. We do this in the case of Sweden, where a set of firms are covered by both types of regulations, i.e., the Swedish CO2 tax and the European Union’s Emissions Trading System (EU ETS). This provides us with an excellent case study as it allows us to disentangle the costs of each regulation from other firm-specific variables that might affect the overall cost of MRV procedures. Our results indicate that the MRV costs of CO2 taxation do not depend on firms’ emissions, while they do in the case of the EU ETS. For firms of equivalent emissions’ size, the MRV costs are lower for CO2 taxation than for the EU ETS, which confirms the general view that regulating emissions upstream by means of a CO2 tax yields lower transaction costs vis-á-vis downstream regulation by means of emission trading.
To the best of our knowledge, this is the first paper comparing empirically the transaction costs of the monitoring, reporting and verification (MRV) required by two environmental regulations aimed to cost-efficiently reduce greenhouse gas emissions: a carbon dioxide (CO2) tax and an emissions trading system. We do this in the case of Sweden, where a set of firms are covered by both types of regulations—the Swedish CO2 tax and the European Union’s Emissions Trading System (EU ETS). Our results indicate that there is a significant degree of heterogeneity in the transaction costs of the firms in our sample. Moreover, for some of the firms, the transaction costs are high when compared with the actual cost of the CO2 tax and the price of the EU ETS. Furthermore, we find that the MRV costs are lower for CO2 taxation than for the EU ETS, which confirms the general view that regulating emissions upstream via a CO2 tax yields lower transaction costs vis-á-vis downstream regulation via emissions trading.
We investigate the process of electricity price formation in the Swedish intraday market, given a large share of wind power in the Swedish electricity system. According to Karanfil and Li's (2017) approach, if the intraday market is efficient, with large shares of intermittent electricity in the entire electricity system, intraday prices should send signals based on scarcity pricing for balancing power. Based on this theory, we analyze Swedish electricity market data for the period 2015–2018 and find that the Swedish intraday market, despite its small trading volumes, is functioning properly. In particular, our results show that intraday price premia mostly respond to wind power forecast errors and other imbalances resulting from either supply or demand sides of the electricity market, as they should if the intraday market is efficient. The results of wind power forecast errors hold for central and southern Sweden, but not for northern Sweden where the share of wind power production is still very small. However, we find no effect of unplanned nuclear power plant outages on intraday price premia.
Using a cross-country firm-level dataset this study empirically analyses how the implemented renewable electricity promotion systems Tradable Green Certificates vs. Feed-in-Tariffs affected the profitability of the electricity production sector in Europe during the 2002-2010 period. In particular, it tests the hypothesis that due to market imperfections, namely because of higher investment risk, higher capital constraints and higher transaction costs, TGC schemes will be associated with excess profits for renewable electricity generating firms. The results somewhat support this hypothesis, showing that electricity generating firms, operating in EU countries that implemented TGC, were more profitable compared to FIT firms.
Until now, there has been little empirical evidence that EU Emissions Trading Scheme (ETS) transaction costs are incurred at firm level. The transaction costs (internal costs, capital costs, consultancy and trading costs) incurred by Irish firms under the EU ETS during its pilot phase (2005–2007) were measured and analysed. Evidence for the sources of transaction costs, their magnitude and the distribution of costs shows that these were mainly administrative in nature. Considerable variation in costs was found due to economies of scale, as the costs per tonne of CO2 were lower for participants with larger allocations. For the largest firms—accounting for over half the emissions—average transaction costs were €0.05 per tonne. However, for small firms, average transaction costs were €2.02—over 18% of the current allowance price. This supports the concerns that transaction costs are excessive for smaller participants. The immediate policy implication is that additional attention will be needed to address different sizes of firms, number of installations per firm, and the size of the initial allocations.
We use a panel dataset of about 5,000 Lithuanian firms between 2003 and 2010, to assess the impact of the EU ETS on the environmental and economic performance of participating firms. Using a matching methodology, we are able to estimate the causal impact of EU ETS participation on C02 emissions, C02 intensity, investment behaviour and profitability of participating firms. Our results show that ETS participation did not lead to a reduction in C02 emissions, while we identify a slight improvement in C02 intensity. ETS participants are shown to have retired part of their less efficient capital stock, and to have made modest additional investments from 2010. We also show that the EU ETS did not represent a drag on the profitability of participating firms.
This study uses the EU public power generating sector as a case study to investigate the environmental efficiency and productivity enhancing performance of the European Union's CO2 Emissions Trading Scheme (EU ETS) in its first phase. Using Data Envelopment Analysis methods, we measure the environmental efficiency and the productivity growth registered in public power generation across the EU over the 1996–2007 period. In the second stage of our analysis we attempt to explain changes in productivity and efficiency over time using econometric techniques. Our analysis suggests two conclusions: carbon pricing led to an increase in environmental efficiency and to a shift outwards of the technological frontier; and, the overly generous allocation of emission permits had a negative impact on both measures. These results are shown to be robust to changes in controls and specifications.
Given the intensifying debates whether governments should use industrial policies to promote particular renewable energy technologies, the main objective of this study is to investigate the long-run effects of renewable energy support policies on economic growth and employment in 15 European Union (EU) member states for the 1990-2012 time period by using panel-data time-series econometric techniques. The first hypothesis is that the EU’s renewable energy support policies lead to technological advancement, followed by economy growth, in the long-run. The second hypothesis states that these policies at least generate an increase in output and employment in the short-run. In summary, our results provide some evidence in support of the second hypothesis, but, in contrary to the similar studies, our findings do not support the first hypothesis that these policies promote growth in the long-run.
Given the intensifying debates on whether governments should promote particular renewable energy technologies, the main objective of this study is to investigate the long-and short-run effects of policy-induced expansion of renewable solar and wind technologies on economic growth and employment in 15 European Union (EU) member states during 1990-2013 by using panel-data time-series econometric techniques. Instead of relying on renewable energy consumption or generation as commonly done in the literature, we focus on the capacity for solar and wind power generation, which is largely a consequence of the EU's renewable energy policies. In summary, we find that, to date, renewable energy policy-induced wind and solar power capacity promotes growth and/or employment in the short run, but these capacity increases do not stimulate economic growth in the long run in the EU-15 region. In fact, our results tend to support the opposite relationship: increases in wind and solar power capacity are associated with negative economic growth, at least at the total economy level.
EU farmers are subject to mandatory cross-compliance measures, requiring them to meet environmental conditions to be eligible for public support. These obligations reinforce incentives for farmers to change their behaviour towards the environment. We apply quasi-experimental methods to measure the causal relationship between cross-compliance and some specific farm environmental performance. We find that cross-compliance reduced farm fertiliser and pesticide expenditure. This result also holds for farmers who participated in other voluntary agro-environmental schemes. However, the results do not support our expectations that farmers who relied on larger shares of public payments had a stronger motivation to improve their environmental performance.
This study provides new evidence on the determinants of environmental expenditure and investment. In particular, it investigates how environmental expenditure and investment of Swedish industrial firms responded to climate policies, such as the European Union's Emission Trading System (EU ETS) and the Swedish CO2 tax, directed to mitigate air pollution. Overall, an important conclusion of this analysis is that climate policies, both on the national and international levels, were highly relevant motivations for firm environmental expenditure. However, the findings do not support the expectations that the EU ETS and the Swedish CO2 tax encouraged investment in air pollution abatement.
This study is one of the first to empirically investigate firm trading behaviour and the importance of permit trading transaction costs, such as information costs and search costs, in the first phase of the European Union’s Emissions Trading System (EU ETS). The signs and significance of our constructed transaction costs proxy variables indicate for a presence of these costs in the initial years of the EU ETS. In particular, this paper shows that ETS firms with the smaller number of installations and with less trading experience were less likely to participate in the European emissions trading market and traded the lower quantities of permits. Furthermore, these firms chose to trade permits indirectly via third parties. This study also supports the concerns that transaction costs could be excessive for smaller participants and firms operating in the new EU member states.
A large body of literature shows that the provision of social comparisons can cause households to reduce residential energy and water use. In this paper, we carry out a field experiment that contributes to this literature in two important ways. First, we study a social comparison treatment that is continuous and communicated via pre-installed in-home displays, which are salient and updated in real time. Second, we estimate the effects of provision of social comparisons on two distinguished resources – electricity and water – in the same experimental setting. We find that, on average, our social comparison reduces daily residential energy consumption by 6.7 percent but has no effect on overall residential water use. The electricity savings are impersistent and occur in the evening hours, which only slightly overlap with peak hours. We argue that electricity conservation due to social comparisons is driven by short-run changes in households’ electricity saving behavior
With policies to promote power generation from renewable energy sources (RES) becoming important part of climate and energy policy worldwide, there is now considerable interest in understanding how these different market-based mechanisms affect power generating firms in practice. The existing theory provides conflicting guidance regarding profitability of Tradable Green Certificates (TGC) over Feed-in-Tariff (FIT) based policies. Thus, the main goal of this study is to empirically assess the performance of power generating firms operating in the TGC scheme environment relative to the performance of power generating firms operating under alternatives RES support mechanisms. The main finding of this study is that, in Europe, TGC schemes are associated with higher returns for power generating firms. This supports the hypothesis that higher investment uncertainty induced by the TGC policy nature coupled with some market imperfections lead to higher profits for electricity producers operating in TGC schemes.
