  • Why large-scale bioenergy production on marginal land is unfeasible: A conceptual partial equilibrium analysis
  • 2013
  • record:In_t: Energy Policy. - : Elsevier BV. - 0301-4215. ; 55, s. 454-466
  • swepub:Mat_article_t (swepub:level_refereed_t)abstract
    • A transparent and conceptual partial equilibrium model of global land use is used to explore long-term effects of large-scale introduction of bioenergy, under different policy cases. The transparency of the model, and the consideration of clear-cut policies, provides a clear picture of how main mechanisms of land-use competition work, and how they influence the food and bioenergy systems. The model is subjected to a detailed characterization, in which parameters critical to the results and conclusions are detected and their impacts depicted. A large-scale introduction of bioenergy would raise food prices in all cases/scenarios investigated, and relative price increases of extensively produced crops would be at least twice as high as compared to intensively produced crops. Banning production of bioenergy from the most productive land (limiting production to “marginal land”) would reduce this price impact. However, we show that bioenergy is unlikely to ever be produced on any commercial scale only on land of low productivity. The economic incentives would be strong for owners of more productive land to grow bioenergy anyway and out-compete the more costly production on low yielding land. Large-scale deforestation would become attractive in response to increased bioenergy demand, especially for extensive production systems such as grazing.

  • A cobweb model of land-use competition between food and bioenergy crops
  • 2015
  • record:In_t: Journal of Economic Dynamics and Control. - : Elsevier BV. - 0165-1889. ; 53, s. 1-14
  • swepub:Mat_article_t (swepub:level_refereed_t)abstract
    • We present a model of interacting cobweb markets and apply it to land-use competition between food and bioenergy crops. In our model the markets are interlinked on the supply side by the limited availability of land. Therefore, instabilities are transferred between the markets and we find that bioenergy demand affects food price volatility. The agents in the model have heterogeneous production capacities, representing variation in global land quality. When we allow agents to choose price predictor, we find that a more sophisticated (but costly) predictor is concentrated to some key parcels of land, which enables the system to reduce instability significantly. The system can also be brought closer to a stable state by introducing costs for changing production type, but it may then be shifted away from the optimum situation predicted by the corresponding equilibrium model.

  • A conceptual partial equilibrium model of global agricultural land use
  • 2012
  • swepub:Mat_article_t (swepub:level_scientificother_t)abstract
    • We introduce a conceptual partial equilibrium model of global agricultural land use, based on heterogenous land quality--an area that has received less theoretical attention than location theory. The model is based on maximization of land rent at each parcel through choice of crop and input intensity. Mechanisms of land rent and land-use competition are illustrated in a transparent way, which can be used for e.g. policy testing and for improved understanding of results from larger land-use models. A strength with this approach is that the model to a large extent can be analytically explored. We show how different crops are optimally distributed on land according to their respective area-dependent cost, i.e. costs paid per area regardless of yield. Crops with high such costs are grown on more productive land and crops with low such costs are grown on less productive land, in equilibrium. The equilibrium solution of the model is unique. Further we show how prices are connected between crops that compete for land.

  • Evolutionary dynamics in game-theoretic models
  • 1997
  • record:In_t: The Economy as an Evolving Complex System II. ; , s. 337-368
  • swepub:Mat_conferencepaper_t (swepub:level_refereed_t)abstract
    • A number of evolutionary models based on the iterated Prisoner's Dilemma with noise are discussed. Different aspects of the evolutionary behaviour are illustrated (i) by varying the trickiness of the game (iterated game, mistakes, misunderstandings, choice of payoff matrix), (ii) by introducing spatial dimensions, and (iii) by modifying the strategy space and the representation of strategies. One of the variations involves the finitely iterated game, that has a unique Nash equilibrium of only defecting strategies, and it is illustrated that when a spatial dimension is added, evolution usually avoids this state. The finite automaton representation of strategies is also revisited, and one model shows an evolution of a very robust error-correcting strategy for the Prisoner's Dilemma game.

  • Impacts on Stability of Interdependencies Between Markets in a Cobweb Model
  • 2015
  • record:In_t: Lecture Notes in Economics and Mathematical Systems. - Cham : Springer International Publishing. - 2196-9957 .- 0075-8442. ; 676, s. 195-205
  • swepub:Mat_article_t (swepub:level_refereed_t)abstract
    • We present a cobweb model of interdependent markets on both the sup- ply and demand sides and apply it to a food and bioenergy framework. The supply side is represented by an agent based model of global land use while the consumer side consists of interlinked demand functions. We find that the two kinds of inter- dependencies have opposing effects. Linking markets on the supply side transfers instabilities within the system and may cause price fluctuations in previously sta- ble markets. Market interdependency on the demand side, on the other hand, has a stabilizing effect.

  • OPEC strategies and oil rent in a climate conscious world
  • 2009
  • record:In_t: The Energy Journal. - 0195-6574. ; 30:3, s. 23-50
  • swepub:Mat_article_t (swepub:level_refereed_t)abstract
    • In the UNFCCC process, energy exporting countries (primarily OPEC) claim compensation for losses in expected oil rent due to CO 2 mitigation measures. However, there are mechanisms that may raise rather than lower the oil rent. If a carbon price is implemented universally, the cost of using oil substitutes such as unconventional oil or synthetic diesel from coal or natural gas will increase even more than the cost of using conventional oil. Here, a dynamic model that takes into account OPEC's dominant position in the world's liquid fuel market is developed in order to analyze these mechanisms. In this model, OPEC is assumed to act as strategic leader while all other liquid fuel producers act as price-takers. We find that the net present value of OPECs conventional oil rent increases by about 5% due to the carbon prices needed to reach stringent CO 2 emission targets. For less ambitious targets, the increase in oil rent could be even higher. An extensive sensitivity analysis is also performed, which corroborates the main result.

  • Financing the Transition Toward Carbon Neutrality—an Agent-Based Approach to Modeling Investment Decisions in the Electricity System
  • 2021
  • record:In_t: Frontiers in Climate. - : Frontiers Media SA. - 2624-9553. ; 3
  • swepub:Mat_article_t (swepub:level_refereed_t)abstract
    • Transitioning to a low-carbon electricity system requires investments on a very large scale. These investments require access to capital, but that access can be challenging to obtain. Most energy system models do not (explicitly) model investment financing and thereby fail to take this challenge into account. In this study, we develop an agent-based model, where we explicitly include power sector investment financing. We find that different levels of financing constraints and capital availabilities noticeably impact companies' investment choices and economic performances and that this, in turn, impacts the development of the electricity capacity mix and the pace at which CO2 emissions are reduced. Limited access to capital can delay investments in low-carbon technologies. However, if the financing constraint is too relaxed, the risk of going bankrupt can increase. In general, companies that anticipate carbon prices too high above or too far below the actual development, along with those that use a low hurdle rate, are the ones that are more likely to go bankrupt. Emissions are cut more rapidly when the carbon tax grows faster, but there is overall a greater tendency for agents to go bankrupt when the tax grows faster. Our energy transition model may be particularly useful in the context of the least financially developed markets.
