Model closure and price formation under switching grain market regimes in South Africa

Ferdinand Meyer; Patrick C. Westhoff; Julian Binfield; Johann F. Kirsten

Abstract This paper develops the structure and closure of an econometric regime-switching model within a partial equilibrium framework that has the ability to generate reliable estimates and projections of endogenous variables under market switching regimes. Models used in policy evaluation usually either ignore the possibility of regime switching using just a single method of price determination based on average effects, or incorporate highly stylised components that may not reflect the complexities of a particular market. This paper proposes an approach that the authors believe allows the incorporation of features of regime switching in a multisector commodity level model that capture salient features of the South African market and therefore are able to produce more reliable projections of the evolution of the sector under alternative shocks.

‘Deal’ or ‘No Deal’? Impacts of Alternative Post-Brexit Trade Agreements on UK Agriculture

Siyi Feng; Myles Patton; Julian Binfield; John Davis

Brexit will have important implications for UK agricultural commodity markets due to potentially significant changes to trade flows. We quantify the sectoral impacts on UK agriculture of three illustrative scenarios, which capture a broad range of potential trade arrangements: Bespoke Free Trade Deal, WTO Default and Unilateral Trade Liberalisation. It is estimated that the projected market impacts are relatively small if the UK negotiates a Bespoke Free Trade Agreement with the EU. The projected impacts are much greater under the two other scenarios, which capture potential trade arrangements if ‘no deal’ is reached. The high tariffs imposed under the WTO default scenario lead to significant adjustments in trade between the UK and EU†27, with the impact on the domestic UK market depending on whether the UK is a net importer or a net exporter of the relevant commodity. All sectors experience price and production declines under the trade liberalisation scenario in which the UK unilaterally sets tariffs on imports from both the EU†27 and the rest of the world to zero; the impacts are particularly severe in the beef and sheep sectors where international competition is very strong.Le Brexit aura des rA©percussions importantes sur les marchA©s des produits agricoles du Royaume†Uni car les flux commerciaux pourraient varier notablement. Nous quantifions les impacts sectoriels sur lagriculture du Royaume†Uni de trois scA©narios illustratifs, qui couvrent un large A©ventail daccords commerciaux potentiels: Accord de libre†A©change sur mesure, OMC par dA©faut et LibA©ralisation commerciale unilatA©rale. Selon les projections, les impacts sur les marchA©s sont relativement faibles si le Royaume†Uni nA©gocie un accord de libre†A©change sur mesure avec lUnion europA©enne. Les impacts projetA©s sont beaucoup plus importants dans les deux autres scA©narios, qui permettent de prendre en compte les accords commerciaux potentiels si lon ne parvient pas A saccorder. Les tarifs A©levA©s imposA©s dans le cadre du scA©nario OMC par dA©faut entraA®nent des ajustements importants dans les A©changes entre le Royaume†Uni et lUE A 27, limpact sur le marchA© intA©rieur du Royaume†Uni variant selon que le pays est importateur net ou exportateur net du produit concernA©. Tous les secteurs enregistrent des baisses de prix et de production dans le cadre du scA©nario de libA©ralisation du commerce dans lequel le Royaume†Uni A©tablit unilatA©ralement des tarifs nuls sur les importations de lUE A 27 et du reste du monde; les impacts sont particuliA¨rement sA©rieux dans les secteurs bovins et ovins oA¹ la concurrence internationale est trA¨s forte.Durch mA¶glicherweise signifikante A„nderungen der HandelsstrA¶me wird der Brexit starke Auswirkungen auf die AgrarmA¤rkte im Vereinigten KA¶nigreich haben. Wir messen die sektorspezifischen Auswirkungen auf die Landwirtschaft im Vereinigten KA¶nigreich mithilfe dreier anschaulicher Szenarien, die ein breites Spektrum potenzieller Handelsregelungen abbilden: MaAŸgeschneiderte Freihandelsabkommen, WTO Standard und Unilaterale Handelsliberalisierung. Es wird geschA¤tzt, dass die vorhergesagten Auswirkungen auf den Markt relativ gering sind, wenn das Vereinigte KA¶nigreich ein MaAŸgeschneidertes Freihandelsabkommen mit der EU aushandelt. Die vorhergesagten Auswirkungen der beiden anderen Szenarien, die mA¶gliche Handelsabkommen darstellen fA¼r den Fall, dass es zu “Kein Abkommen†kommt, sind um einiges gravierender. Die hohen ZA¶lle, die im WTO Standard†Szenario erhoben werden, fA¼hren zu signifikanten Anpassungen des Handels zwischen dem Vereinigten KA¶nigreich und den EU†27†Mitgliedsstaaten und haben damit Einfluss auf diejenigen inlA¤ndischen MA¤rkte des Vereinigten KA¶nigreichs, die davon abhA¤ngig sind, ob das Vereinigte KA¶nigreich ein Nettoimporteur oder Nettoexporteur des jeweiligen Rohstoffes ist. Im Szenario Handelsliberalisierung, in dem die UK die ZA¶lle auf Importe aus den EU†27 und dem Rest der Welt unilateral auf null setzt, werden alle Bereiche Preis und ProduktionsrA¼ckgA¤nge erleben. FA¼r die Rinder†und Schafwirtschaft, in der der internationale Wettbewerb sehr stark ist, werden die Auswirkungen besonders massiv sein.

Stochastic Partial Equilibrium Modelling: An Application to Crop Yield Variability

Siyi Feng; Julian Binfield; Myles Patton; John Davis

Market volatility is of increasing concern within the agricultural sector of the EU and consequently the FAPRI-UK and EU-GOLD partial equilibrium modelling system is being developed to produce stochastic projections, which reflect underlying uncertainties. This chapter describes the underlying methodology. In the initial simulations, only one source of uncertainty, namely crop yield variability within the EU, is examined. Positive correlations among crop yield deviates amplify variations in crop production. This is supported by our results of the experimental simulations in which correlations among crop yield deviates are taken into account and compared to results where they are not addressed. Variability in output value varies widely depending on the aggregation level under consideration. In particular, at levels below where prices are determined, output value variability is larger than either production variability or price variability alone, supporting the potential need for risk management policy.

Uneven Natural Hedge Effects in the Wheat Sector and Implications for Risk Management Tools

Siyi Feng; Myles Patton; Julian Binfield; John Davis

Summary n nRisk management tools have risen up the EU agricultural policy agenda in recent years due to greater market volatility. Market mechanisms can provide a natural hedge effect that moderates variability in revenue and income but not all regions benefit from this effect to the same extent. Core producing regions tend to benefit more while peripheral producing regions with dissimilar weather conditions benefit relatively little. We quantify the strength of natural hedge effects in the EU soft wheat sector. The two largest producing countries – France and Germany – have highly positively correlated yields and production thus driving EU wheat price changes. Our simulation shows that this hedge effect moderates revenue variability in these two countries by more than a third compared to price variability when crop yield is the only uncertainty source. By contrast, revenue variability in peripheral producing regions is consistently larger than price variability. This implies that there is a greater need for risk management tools in peripheral producing regions than in the core ones. The need for risk management tools is strongly linked to market conditions and so it is imperative that local characteristics are adequately considered if the over-arching risk management policy framework is to be designed and set up at the EU level. n n n nLes outils de gestion du risque ont grimpe dans lordre du jour de la politique agricole europeenne dans les dernieres annees, du fait de laugmentation de la volatilite des marches. Les mecanismes de marche peuvent apporter une couverture naturelle qui modere la variabilite des recettes et des revenus, mais toutes les regions ne profitent pas de cet effet dans la meme mesure. Les principales regions productrices tendent a en profiter davantage alors que les regions de production peripherique avec des conditions meteorologiques differentes en retirent peu davantages. Nous mesurons la force des effets de couverture naturelle dans le secteur du ble tendre europeen. Les rendements et la production des deux principaux pays producteurs – la France et lAllemagne – sont fortement lies et ont donc une force influence sur les variations du prix du ble dans lUnion europeenne. Nos simulations montrent que cet effet de couverture reduit la variabilite des recettes dans ces deux pays de plus dun tiers par rapport a celle enregistree lorsque le rendement des cultures est la seule source de variabilite. Par contre, dans les regions de production peripherique la variabilite des recettes est toujours plus forte que la variabilite des prix. Cela signifie quil y a un plus grand besoin doutils de gestion du risque dans les regions de production peripherique que dans les celles de production principale. Ce besoin est fortement lie aux conditions du marche et il est indispensable de bien considerer les caracteristiques locales si le cadre general de la politique de gestion du risque est concu et etabli au niveau de lUnion europeenne. n n n nAufgrund zunehmender Marktvolatilitat haben Instrumente zum Risikomanagement auf der Agenda der europaischen Agrarpolitik im Laufe der letzten Jahre einen hoheren Stellenwert erhalten. Marktmechanismen konnen sich wie ein naturlicher Hedgingeffekt auswirken, der die Ertrags- und Einkommensschwankungen abmildert; jedoch profitieren nicht alle Regionen in gleichem Mase davon. Hauptanbaugebiete werden einen eher hoheren Nutzen haben, wahrend entlegenere Anbaugebiete mit wechselnden Witterungsbedingungen relativ wenig profitieren. Wir quantifizieren die Auswirkungen von naturlichen Hedgingeffekten im europaischen Weichweizensektor. In den beiden grosten Erzeugerlandern Frankreich und Deutschland herrscht eine starke Korrelation zwischen Ertragen und Produktion, was die Weizenpreisanderungen in der EU antreibt. Unsere Simulation verdeutlicht, dass der Hedgingeffekt die mit den Preisschwankungen verbundenen Ertragsschwankungen in diesen beiden Landern um mehr als ein Drittel auffangt, wenn es sich beim Bodenertrag um den einzigen Unsicherheitsfaktor handelt. Im Gegensatz dazu sind die Ertragsschwankungen in entlegeneren Anbaugebieten durchweg hoher als die Preisschwankungen. Daraus folgt, dass entlegenere Anbaugebiete einen hoheren Bedarf an Instrumenten zum Riskomanagement haben als Hauptanbaugebiete. Der Bedarf an Instrumenten zum Riskomanagement ist eng mit den Marktbedingungen verknupft; daher ist es unerlasslich, die Gegebenheiten vor Ort hinreichend zu berucksichtigen, wenn der allumfassende politische Rahmen zum Risikomanagement entworfen und auf EU-Ebene implementiert werden soll.

The Tunisia Wheat Market in the Context of World Price Volatility: A Stochastic Partial Equilibrium Approach

Abderraouf Laajimi; Kateryna G. Schroeder; William H. Meyers; Julian Binfield

ABSTRACT Food security is a key objective of agricultural and food policy in Tunisia. The 2007–2008 food crisis highlighted the negative impacts of price volatility on international markets both in terms of food insecurity and budget exposure. Tunisian food subsidy expenditures ranged from

710 million in 2006–2010, so volatile world prices meant volatile subsidy costs. Moreover, cereal production in Tunisia still has much instability due to climate conditions, which also influences imports and, consequently, subsidy expenditures. This study applies a structural model to conduct stochastic analyses of trade and policy impacts on food security and budget expenditures in the Tunisian wheat market. The methodology disaggregates durum wheat and soft wheat markets and generates projections of import prices of durum wheat and soft wheat, using projections of world prices provided by the Food and Agricultural Policy Research Institute at University of Missouri (FAPRI-MU). The key innovation is the generated stochastic analyses of subsidy costs based on stochastic world price projections and stochastic domestic wheat yields based on historic yield variances. The analysis highlights the sensitivity of subsidy costs to world prices, volumes imported and domestic production, so that alternative policy tools can be considered.
