Effects of Increased Biofuel Blending on Demand for Biomass, Food Production and Commodity Prices in Eastern Germany AgEcon
Zeller, Heiko; Haring, Anna Maria; Khachatryan, Armen.
Renewable resources are gaining importance in modern society due to their expected positive effects on agriculture, the environment and the economy. To support renewable energy from biomass the EU promotes the cultivation of energy crops. A spatial equilibrium model is applied based on the concept of maximizing net welfare, to provide information whether energy crop production competes with food production for land area and to show the effects of increased biofuel demand on food prices. The Model of Interregional Trade of Energy Crops (ITEC) refers to Eastern Germany and adjacent areas of Poland. Results show that the regions produce enough feedstocks to meet the demand for food and biofuel production. In many cases both food crops and biofuels are either...

An Ex post Evaluation of Economic Impacts of Foot-and-Mouth Disease on Taiwan Using a Dynamic Computable General Equilibrium Model AgEcon
Hsu, Shih-Hsun; Lee, Duu-Hwa; Chang, Ching-Cheng; Lin, Hsing-Chun; Yang, Tzu-Chiang.
The outbreak of foot-and-mouth disease (FMD) in 1997 has resulted in significant losses to Taiwan's hog industry which was the most important industry in Taiwan's agricultural sector at that time. Hog farmers have suffered great losses due to the cost of slaughtering infected hogs and reduced revenues in the hog market. Furthermore, all pork exports are prohibited according to the Office International des Epizooties (OIE) regulation. There have been a number of ex ante studies that have quantified the potential impacts of FMD on Taiwan's economy (e.g., Tsai 1999, Lin and Hsu 1999). That is, the potential impact assessment was done when the event of FMD just broke out. This article provides an ex post economy-wide assessment of the FMD impacts on...

The impact of property rates on agricultural land, focusing on Gauteng AgEcon
Reynolds, Sanri; van Schoor, Melt.
Municipalities across the country are in the process of implementing property rates on all property, following the Local Government: Property Rates Act (2004) that came into effect on 1 July 2005. This study investigates the economic impact of property rates on agricultural land, using a static computable general equilibrium model. The direct and indirect effects of property rates on the macro-economy, factor incomes, household welfare, prices and agricultural output are discussed. The results indicate that the impact of raising property rates depends on the use made of the additional revenue by government. There is a small negative impact on the economy and the overall welfare of households decline if government spends the additional revenue. On the other...

Assessing the Economic Impacts of Climate Change. An Updated CGE Point of View AgEcon
Bosello, Francesco; Eboli, Fabio; Pierfederici, Roberta.
The present research describes a climate change integrated impact assessment exercise, whose economic evaluation is based on a CGE approach and modeling effort. Input to the CGE model comes from a wide although still partial set of up-to-date bottom-up impact studies. Estimates indicate that a temperature increase of 1.92°C compared to pre-industrial levels in 2050 could lead to global GDP losses of approximately 0.5% compared to a hypothetical scenario where no climate change is assumed to occur. Northern Europe is expected to benefit from the evaluated temperature increase (+0.18%), while Southern and Eastern Europe are expected to suffer from the climate change scenario under analysis (-0.15% and -0.21% respectively). Most vulnerable countries are the...

A multi-regional general equilibrium model to assess policy effects at regional level AgEcon
Lovo, Stefania; Magnani, Riccardo; Perali, Carlo Federico.
This paper develops a multi-regional general equilibrium model (MEG-R) to compare the social desirability of the CAP reform in the three Italian macro-regions: North, Center and South. The model employs a mixed complementary framework that allows for the decision of not producing a particular crop in one or more regions and presents an attempt to model interregional trade flows. The model incorporates the links between production and consumption that characterize farm household’s behavior and allows for heterogeneous household responses across regions. Results show a general tendency to reallocations from cereal crops to forage that appear more severe in the South. In this region, the reduction in crops cannot be translated into an effective expansion of...

The economic assessment of changes in ecosystem services: and application of the CGE methodology AgEcon
Bosello, Francesco; Eboli, Fabio; Parrado, Ramiro; Nunes, Paulo A.L.D.; Ding, Helen; Rosa, Renato.
The present study integrates Computable General Equilibrium (CGE) modelling with biodiversity services, proposing a possible methodology for assessing climate-change impacts on ecosystems. The assessment focuses on climate change impacts on carbon sequestration services provided by European forest, cropland and grassland ecosystems and on provisioning services, but provided by forest and cropland ecosystems only. To do this via a CGE model it is necessary to identify first the role that these ecosystem services play in marketable transactions; then how climate change can impact these services; and finally how the economic system reacts to those changes by adjusting demand and supply across sectors, domestically and internationally

GHG Mitigation Policies in Livestock Sectors: Competitiveness, Emission Leakage and Food Security AgEcon
Golub, Alla A.; Henderson, Benjamin B.; Hertel, Thomas W..
Recent research on livestock’s role in climate change has raised awareness about contribution that livestock climate policies can make to global mitigation efforts, and has increased the likelihood that mitigation policies will eventually be imposed on the sector. This study investigates effects of GHG mitigation policies on livestock sectors emissions and production by regional sector under a range of global mitigation polices that are broadly aligned with the different responsibilities of developed and developing countries under the UNFCCC. The study also examines emission leakage effects, impacts on food security in developing countries, and the implications of large informal livestock sectors in regions such as Sub Saharan Africa.

Are The Poverty Effects of Trade Policies Invisible? AgEcon
Verma, Monika; Valenzuela, Ernesto; Hertel, Thomas W..
With the advent of the WTO’s Doha Development Agenda, as well as the Millennium Development Goals aiming to reduce poverty by 50 percent by 2015, poverty impacts of trade reforms have attracted increasing attention. This has been particularly true of agricultural trade reform due to the importance of food in the diets of the poor, relatively higher protection in agriculture, as well as the heavy concentration of global poverty in rural areas where agriculture is the main source of income. Yet some in this debate have argued that, given the extreme volatility in agricultural commodity markets, the additional price and poverty impacts due to trade liberalization might well be undetectable. This paper formally tests this “invisibility hypothesis” via...

Capital Malleability and the Macroeconomic Costs of Climate Policy AgEcon
Lanzi, Elisa; Sue Wing, Ian.
This paper argues for introducing the role of capital malleability into the analysis of environmental policies. The issue is explored by means of a theoretical model, a numerical analysis and a computable general equilibrium (CGE) model. Considering the three approaches together is fundamental in obtaining theory-compatible policy-relevant results. The model outcomes reveal differences between results under separate assumptions regarding the malleability of capital. When capital is imperfectly malleable a carbon policy is less effective than under the assumption of perfect malleability of capital. Therefore, it is important that, especially for the analysis of short-term environmental regulations, the issue of capital malleability is taken into...

An EU-Canada bilateral trade agreement: A DefraTAP application AgEcon
Kitou, Elisavet; Philippidis, George.
The first round of negotiations held in Ottawa on the 19th October, 2009, heralded the opening of bilateral trade talks intent on reaching a Canadian-European Union (EU27) free trade area (FTA) agreement. A second round of negotiations were staged in Brussels in January, whilst further rounds are scheduled for 2010, with the longer term aim of ratifying an agreement within 24-30 months. Although stumbling blocs will be encountered, the divergent political interests of each region are compatible. In Canada, a FTA with its second largest trading partner offers a viable alternative to its current overdependence on the US. Similarly, the EU27 sees an opportunity to regain a competitive foothold in the North American market. This paper re-examines the long run...

Sectoral and welfare effects of the global economic crisis on Uganda: a recursive dynamic CGE analysis AgEcon
Twimukye, Evarist P.; Matovu, John Mary; Levine, Sebastian; Birungi, Patrick.
This paper analyses the impact of the global economic and financial crisis on Uganda notably on macro-economic aggregates, sectoral output and household welfare, and the potential role of fiscal policy and reform in mitigating the impacts. We find that second round effects from a reduction in financial inflows such as remittances, foreign direct investments and overseas development assistance, as well as reduction in international demand from cash crops such as cotton, tea and coffee, could lead to a reduction in economic growth by 0.6 percentage points on average annually over the period 2008- 2010 compared to a baseline reflecting pre-crisis conditions. A surge in regional exports and early counter-cyclical policies in particular are found to dampen the...

The Economy-wide Greenhouse Gas Impacts of the Biofuels Boom (or Bust) AgEcon
Birur, Dileep K.; Golub, Alla A.; Hertel, Thomas W.; Rose, Steven K..
Several studies in the recent past have offered a contrasting and wide range of perspectives on economic and environmental implications of biofuels. In this study we develop a comprehensive and consistent framework for analyzing the global economic interactions and the direct and indirect impacts of biofuels production on greenhouse gas (GHG) emissions. We utilize a global Computable General Equilibrium (CGE) model which consists of interaction of energy commodities with explicit biofuels and their by-product sectors, land endowment classified by agro-ecological zones, and emission of four major GHGs - carbon dioxide, methane, nitrous oxide, fluorinated gases from agricultural and economic activities, including emissions associated with biofuel feedstock,...

The welfare impact of targeted transfers to poor households AgEcon
Pauw, Kalie.
Despite widespread poverty there is general consensus among policymakers about the preference of targeted welfare transfers over non-targeted grants due to the budgetary implications of the latter. Targeting, however, adds to the administrative complexities of disbursing welfare grants, thus introducing a cost dimension that is as yet largely unexplored. In this paper a series of targeted transfer simulations are run in a general equilibrium model calibrated with a Social Accounting Matrix for South Africa. Deficit financing and tax replacement policies are considered as financing options, assuming a hypothetical budget constraint of R15 billion. The effectiveness of broad targeting and a low per capita transfer value versus narrow targeting and high...

Imports in the Washington State Economy: Importance and Regional Effects of Import Liberalization AgEcon
Wieck, Christine; Wahl, Thomas I..
This paper focuses on the import side of a regional economy quantifying the economic impact of import levels and trade liberalization. An innovation represents the linkage of a regional with a national model by combining two separate Computable General Equilibrium models into one framework. This allows for import price formation in liberalization scenarios on the national level and subsequent incorporation of these nationally simulated prices into the regional model. The regional model is applied to Washington State, one of the most trade dependent states of the U.S, the national model to the U.S. Data for the two identically structured models origin from the IMPLAN database which divides the U.S. and Washington economy into 509 industries. For both...

The Incentives to Participate in, and the Stability of, International Climate Coalitions: A Game-theoretic Analysis Using the Witch Model AgEcon
Bosetti, Valentina; Carraro, Carlo; De Cian, Enrica; Duval, Romain; Massetti, Emanuele; Tavoni, Massimo.
This paper uses WITCH, an integrated assessment model with a game-theoretic structure, to explore the prospects for, and the stability of broad coalitions to achieve ambitious climate change mitigation action. Only coalitions including all large emitting regions are found to be technically able to meet a concentration stabilisation target below 550 ppm CO2eq by 2100. Once the free-riding incentives of non-participants are taken into account, only a “grand coalition” including virtually all regions can be successful. This grand coalition is profitable as a whole, implying that all countries can gain from participation provided appropriate transfers are made across them. However, neither the grand coalition nor smaller but still environmentally significant...
