The failure to fully internalize externalities from production and consumption, including on future generations, is supposed to be at the core of the perceived failure to ensure (ecological) sustainability within the realm of antitrust enforcement. While some argue that sustainability should constitute a goal in itself that must be balanced against economic efficiency in antitrust analysis, we instead want to explore whether and how sustainability can be incorporated into a consumer welfare approach. We make a key distinction between what we term an individualistic and a collective consumer welfare analysis. Within an individualistic consumer welfare analysis, consumers’ willingness-to-pay is measured ceteris paribus, holding other consumers’ choices fixed. In a collective consumer welfare analysis, consumers may express their willingness-to-pay also for the choices of others and, thereby, also for the reduction of externalities on themselves. Borrowing from environmental and resource economics, we also discuss more indirect ways of incorporating such externalities. And we critically assess the possibility of ‘laundering’ consumers’ sustainability preferences in the light of supposed biases and cognitive limitations. Finally, we relate our analysis to the Draft Horizontal Guidelines of the European Commission, published in March 2022. antitrust, consumer welfare, conjoint analysis, contingent valuation, Draft EU Horizontal Guidelines, environmental economics, externalities, laundering preferences, sustainability, willingness-to-pay

This paper constitutes a first analysis on stock returns and stock return volatility of energy corporations from the Eurozone. According to our results, the gas market does not play a role for the pricing of Eurozone energy stocks. However, changes in the Euro to U.S. Dollar exchange rate as well as developments at the money and especially at the oil market strongly affect returns of the energy stock portfolios analyzed. While oil price hikes negatively impact on stock returns of European utilities, they lead to an appreciation of oil and gas stocks. Most importantly, we show that oil market volatility negatively affects European oil and gas stocks. In contrast, energy stock volatility is not driven by volatility of the resource market, but only by its own dynamics.

This paper examines the interrelationships between energy consumption, foreign direct investment and economic growth using dynamic panel data models in simultaneous-equations for a global panel consisting of 65 countries. The time component of our dataset is 1990-2011 inclusive. To make the panel data analysis more homogenous, we also investigate this interrelationship for a number of sub-panels which are constructed based on the income level of countries. In this way, we end up with three income panels; namely, high income, middle income, and low income panels. In the empirical part, we draw on growth theory and augment the classical growth model, which consists of capital stock, labor force and inflation, with foreign direct investment and energy. Generally, we shows mixed results about the interrelationship between energy consumption, FDI and economic growth.

Sectoral heterogeneity is crucial to address several economic questions. This paper provides a detailed mapping of sectoral production possibility frontiers, using different nesting structures and levels of aggregation (primary, secondary, tertiary activities and energy-intensive firms). Elasticities of substitution between capital, labour and energy are identified by employing an international multi-sector dataset, accounting for biased technological change and normalising the production function to clusters of observations. Complementarity dominates, with the noteworthy exception of the capital-labour composite, close to Cobb-Douglas. I also present some stylized facts relating substitution elasticities to sectoral characteristics.

We analyze the impact of carbon and greenhouse gas emissions on firms’ accounting and market performance. Over a sample of 115 non-financial firms from 9 European countries during the 2008-2016 period, our results suggest that higher volume of both country-level carbon and greenhouse emissions have, on average, a positive and statistically significant impact on firms’ accounting performance. However, no statistical effect is found in terms of stock market performance. The results are more relevant in the case of firms with higher levels of equity and higher levels of intangible assets. We document the existence of an inverse U-shaped relation between country-level greenhouse emissions and firms’ performance suggesting that, after a certain point, greenhouse gas emissions negatively affect firms’ performance. Our results are robust to different estimation technics and control variables, to the consideration of the financial crisis period, and to the inclusion of financial firms in the sample.

The economic evaluation of ultra-long-lived investment projects is not only challenging due to the choice of the planning horizon but also due to the discounting of future uncertain cash flows. Thus, for real world investment decisions a better understanding of the project’s risks and their effect on the project’s value is crucial. If long-term investments are modeled, stochastic processes may be used to reflect the uncertain development of future prices and cash flows. The choice of the stochastic process is consequently an essential assumption in the modeling process. This paper critically discusses the risk of ultra-long-lived investment projects implied if future pay-off’s are assumed to follow geometric Brownian motion processes. In our analysis, we distinguish between projects driven by costs and such driven by revenues. For both kind of projects we compare the value at risk with the returns of a risk-free asset. Therein, the value at risk describes the threshold value of the confidence levels of the uncertain cash flow’s probability density function. The comparison for long time horizons shows that the lower confidence interval exceeds the returns of a risk-free asset used as a benchmark for any choice of the confidence level, which implies that the returns of a “worst-case” scenario (within the assumed confidence interval) will still exceed the returns of a risk-free asset in the long-term perspective. For the case of uncertain future cost, the risk measure is defined as the difference between the expected value and the boundary of the confidence interval. This value is also found to become negative in the long-term perspective.

Abstract We examine drivers of cost overruns in Norwegian development projects in the oil and gas sector. The multivariate longitudinal econometric analysis employs a unique and detailed dataset consisting of 79 different projects between 2000 and 2013. Among the significant results, we find that the unexpected change in economic activity has a positive effect on the overruns, there is a considerable positive momentum in the transitional cost overruns, more experienced operators tend to incur less overruns and finally that the size of the investment of the projects has a positive impact on the overruns. Furthermore, we find evidence that current economic activity matters to an extent, but that the pivotal factor is the unexpected change in activity.

We decompose the economic implications of the Kyoto Protocol at the cross-country level, splitting the total economic impact for each region into contributions from its own emission abatement policy and those from other regions. Our analysis which is based on a large-scale computable general equilibrium model for the world economy indicates that spillover effects are an important consequence of multilateral carbon abatement policies.. We calculate a crosscountry matrix for monetary transfer payments which would have to be assigned on a bilateral basis in order to provide compensation for the international spillovers associated with the implementation of the Kyoto Protocol.
