    Trade Liberalization versus Climate Change Policy for Reducing Greenhouse Gas Emissions in Agriculture: Some Insights from Norway (2015)
    Oxford University Press
    Details
    Publication Date: 2015-08-11
    Description: Using a mathematical programming model of Norwegian agriculture, we explore interconnections between trade liberalization and reductions in greenhouse gas (GHG) emissions. We show that the Doha Round proposals for a new agreement on agriculture through the World Trade Organization would not generate significant reductions in emissions. Further trade liberalization would reduce emissions by cutting agricultural production but would not change production methods. Imposing a carbon tax would lead both to a reduction in output and the extensification of production. In contrast, if farmers are allowed to claim a credit for carbon sequestration the effect is to intensify agricultural production.

    Supply Response, Marginal Cost, and Soil Erosion Implications of Stover-based Biofuels (2015)
    Oxford University Press
    Details
    Publication Date: 2015-08-11
    Description: Existing economic analysis of corn stover as an energy feedstock has not considered potential changes in land use associated with different stover prices. We estimate the response of corn stover supply density to its price driven by changes in land use and examine its implications for a processing plant's pricing strategy and marginal cost, as well as associated changes in soil erosion. We find that plants will exploit the intensive margin as well as the extensive margin to secure additional amounts of stover. Our results show, counterintuitively, that a market for stover may result in lower soil erosion due to reallocations of land to continuous corn with removal, which, combined with no-till farming, results in lower soil erosion than the baseline without stover removal. Also contrary to expectations, using cover crops with stover removal may result in higher soil erosion due to land use changes within the fuel shed associated with optimal pricing.

    Temperature Changes, Household Consumption, and Internal Migration: Evidence from Tanzania (2016)
    Oxford University Press
    Details
    Publication Date: 2016-07-09
    Description: Large rural-urban wage gaps observed in many developing countries are suggestive of barriers to migration that keep potential migrants in rural areas. Using long panel data spanning nearly two decades, I study the extent to which migration rates are constrained by liquidity constraints in rural Tanzania. The analysis begins by quantifying the impact of weather variation on household welfare. The results show how household consumption co-moves with temperature, rendering households vulnerable to local weather events. These temperature-induced income shocks are then found to inhibit long-term migration among men, thus preventing them from tapping into the opportunities brought about by geographical mobility.

    Local warming and violent conflict in North and South Sudan (2015)
    Oxford University Press
    Details
    Publication Date: 2015-04-14
    Description: Our article contributes to the emerging micro-level strand of the literature on the link between local variations in weather shocks and conflicts by focusing on a pixel-level analysis for North and South Sudan between 1997 and 2009. Temperature anomalies are found to strongly affect the risk of conflict, whereas the risk is expected to magnify in a range of 24–31% in the future under a median scenario. Our analysis also sheds light on the competition over natural resources, in particular water, as the main driver of such relationship in a region where pastoralism constitutes the dominant livelihood.

    Dealing with Uncertainty in Agent-Based Simulation: Farm-Level Modeling of Adaptation to Climate Change in Southwest Germany (2015)
    Oxford University Press
    Details
    Publication Date: 2015-04-18
    Description: Climate change will most likely confront agricultural producers with natural, economic, and political conditions that have not previously been observed and are largely uncertain. As a consequence, extrapolation from past data reaches its limits, and a process-based analysis of farmer adaptation is required. Simulation of changes in crop yields using crop growth models is a first step in that direction. However, changes in crop yields are only one pathway through which climate change affects agricultural production. A meaningful process-based analysis of farmer adaptation requires a whole-farm analysis at the farm level. We use a highly disaggregated mathematical programming model to analyze farm-level climate change adaptation for a mountainous area in southwest Germany. Regional-level results are obtained by simulating each full-time farm holding in the study area. We address parameter uncertainty and model underdetermination using a cautious calibration approach and a comprehensive uncertainty analysis. We deal with the resulting computational burden using efficient experimental designs and high-performance computing. We show that in our study area, shifted crop management time slots can have potentially significant effects on agricultural supply, incomes, and various policy objectives promoted under German and European environmental policy schemes. The simulated effects are robust against model uncertainty and underline the importance of a comprehensive assessment of climate change impacts beyond merely looking at crop yield changes. Our simulations demonstrate how farm-level models can contribute to a process-based analysis of climate change adaptation if they are embedded into a systematic framework for treating inherent model uncertainty.

    Is there a term structure in land lease rates? (2015)
    Oxford University Press
    Details
    Publication Date: 2015-12-29
    Description: This article applies the concept of a term structure to agricultural land rental prices. Based on theoretical considerations, we develop a hedonic pricing model that allows for different shapes of the term structure curve while controlling for other price-relevant characteristics. We apply this model to land lease contracts in Saxony-Anhalt. We find an upward-sloping term structure during the agricultural price boom in 2007 and 2008, where market participants expected increasing rental prices. For the subsequent years, however, we detect a single-humped term structure. Hence, market participants revised their expectations and assumed a decline of land rental prices in the long term.

    Irrigation Decisions for Major West Coast Crops: Water Scarcity and Climatic Determinants (2015)
    Oxford University Press
    Details
    Publication Date: 2015-12-13
    Description: This article uses the 2007 Farm and Ranch Irrigation Survey database developed by the U.S. Department of Agriculture to assess the impact of water scarcity and climate on irrigation decisions for producers of specialty crops, wheat, and forage crops. We estimate an irrigation management model for major crops in the West Coast (California, Oregon, and Washington), which includes a farm-level equation of irrigated share and crop-specific equations of technology adoption and water application rate (orchard/vineyard, vegetable, wheat, alfalfa, hay, and pasture). We find that economic and physical water scarcity, climate, and extreme weather, such as frost, extreme heat, and drought, significantly impact producers’ irrigation decisions. Producers use sprinkler technologies or additional water applications to mitigate risk of crop damage from extreme weather. Water application rates are least responsive to surface water cost or groundwater well depth for producers of orchard/vineyard. Water supply institutions influence producers’ irrigation decisions. Producers who receive water from federal agencies use higher water application rates and are less likely to adopt water-saving irrigation technologies for some crops. Institutional arrangements, including access to distinct water sources (surface or ground) and whether surface water cost is fee based, also affect the responsiveness of water application rates to changes in surface water cost. The analysis provides valuable information about how producers in irrigated agricultural production systems would respond and adapt to water pricing policies and climate change.

    An Introduction to the Green Paradox: The Unintended Consequences of Climate Policies (2015)
    Oxford University Press
    Details
    Publication Date: 2015-07-18
    Description: How important is the Green Paradox? We address this question in three ways. First, we present a simple model explaining how announcing a future climate policy may increase carbon emissions today – the Green Paradox effect. This effect is a result of fossil fuel producers increasing their extraction today as a response to a reduction in future resource rents. Second, we examine the theoretical and empirical literature to assess whether green paradoxes are likely to occur, and if they are, whether they are big enough to be of concern for policy makers. We consider several factors that affect the existence of the green paradox, including long-term extraction costs, short-term extraction capacities, the mix of policy instruments, and potential spatial carbon leakage to countries that have no climate policy. We find that these and other factors can sometimes strengthen, but mostly weaken, the case for concern about the green paradox. Third, we identify the lessons the literature offers for policy makers. We argue that in designing climate policy, policy makers need to consider the supply side of the fossil fuel market.

    Introductory Comment-The Green Paradox: A Supply-Side View of the Climate Problem (2015)
    Oxford University Press
    Details
    Publication Date: 2015-07-18
    Description: Why have policies aimed at reducing the demand for carbon not succeeded in slowing down global carbon extraction and CO 2 emissions, and why have carbon prices failed to increase over the last three decades? This comment argues that this is because of the Green Paradox, that is, the anticipation of sales by resource owners who try to preempt the destruction of their markets by green policies. Reviewing some of the conditions under which strong and weak versions of the Green Paradox may emerge, it is argued that there is little hope that green replacement technologies will impose hard price constraints that would keep long-run extraction within a fixed carbon budget and that, therefore, even strong versions of the paradox cannot easily be avoided.

    The Green Paradox in Open Economies: Lessons from Static and Dynamic Models (2015)
    Oxford University Press
    Details
    Publication Date: 2015-07-18
    Description: This article examines how, in a world with incomplete coordination among countries, well-intentioned unilateral environmental policies may actually harm the global environment. This outcome is known as the "Green Paradox." The incentives for free-riding and the challenge of achieving an effective international environmental agreement are reviewed. I examine the various channels that lead to carbon leakage in static models of open economies, and report some simulation results. This is complemented by a review of the potential for Green Paradox outcomes in dynamic open-economy models in which forward-looking firms exploit an exhaustible resource. I show that border tax adjustments can lead to Green Paradox outcomes. I also discuss priorities for future research on environmental policies in a trading world that lacks a central enforcement agency.
