Government intervention and market integration in Indonesian rice markets

Long-run spatial price relationships in Indonesian rice markets and factors affecting the degree of market integration are evaluated using multivariate cointegration tests with weekly price data for the 1982-1993 period. The analysis includes evaluation of pre-self-sufficiency and post-self-sufficiency periods as well as Cot the entire period. The cointegration tests for entire Indonesian rice market, represented by the nine most relevant price series, indicate that relative to the pre-self-sufficiency period, the post-self-sufficiency period has a smaller degree of market integration. The change of the degree of market integration over time indicates that rationalizing of the Indonesian rice price policy beyond 1984 rice self-sufficiency has resulted in a less integrated market. This suggests that the policy shift has allowed the government to decrease its intervention without significantly decreasing market integration, indicating that the private sector is responding to price signals appropriately. It is possible that further reduction in intervention through widening the band between the floor and ceiling price could be accomplished without greatly affecting market integration. Regression results show that government intervention in terms of rice procurement significantly influenced market integration during the period of post-self-sufficiency (1985-1993) and the entire period of 1982-1993. This indicates that this aspect of government intervention has had positive influences on market integration, in contrast to distribution efforts, which were not found to be statistically significant, Procurement prices may be high, and could perhaps be lowered, reducing program costs. Regional per capita income is also found to be positively related to highei levels of market integration, suggesting that in periods of economic growth, government intervention may be decreased, thereby reducing program costs.     

Food scares, market power and price transmission: the UK BSE crisis

This paper is concerned with the impact of food scares, principallythe BSE crisis in the UK, and focuses on price transmissionin vertically related markets. We show that if market powerhas an effect on the farm–retail margin, this determinesthe specification of the cointegrating relationship and thusprovides a test of market power. The results for the UK beefchain suggest that we cannot reject the importance of marketpower. The impact of the BSE crisis on farm prices is foundto be more than double that on retail prices, thus corroboratingpublic concerns regarding a differential impact of food scareson retailers and producers.     

Spatial integration between Finnish and Dutch potato markets

This study estimated a conditional mean model for producer prices of fresh potatoes in Finland and for wholesale selling prices of fresh potatoes in the Netherlands. Unit roots were tested in the Finnish and Dutch price series. Then, an asymmetric error correction model with thresholds was estimated for potato prices between Finland and the Netherlands. Asymmetry was allowed both in short and long-run price transmission. The results suggest that the prices are cointegrated and the arbitrage system is functioning, but with a significant time lag between the Finnish and Dutch potato markets. The price response is also asymmetric in that the Finnish price moves towards a steady state equilibrium faster from above than from below the equilibrium.     

Price integration in the Australian rock lobster industry: implications for management and climate change adaptation

Rock lobster fisheries are Australia's most valuable wild fisheries in terms of both value of production and value of exports. Different states harvest and export different lobster species, with most of the landings being sent to the Hong Kong market. A perception in the Australian lobster industry is that the different species are independent on the export market, such that a change in landings of one species has no impact on the price of the others. This study investigates the market integration of Australian exports to Hong Kong for the four species and different exporting states. Our results indicate all four species and producers/export states are perceived to be substitutes for one another, so that, in the long run, prices paid to operators in the industry will move together. The integrated nature of the Hong Kong export market for Australian lobster suggests that the potential impacts of alternative fisheries management and development strategies at state and species levels cannot be considered in isolation, at least from an economic perspective. In addition, impacts of external shocks affecting production in one state (e.g. climate change) can be expected to affect all Australian lobster fisheries.     

Cross country maize market linkages in Africa: integration and price transmission across local and global markets

In order to study short‐run price shock propagation, we model twenty seven Sub‐Saharan Africa (SSA) domestic maize markets within a Global Vector Autoregression framework. The main purpose is to fully embed multilateral trade flows as a way to better structure local price transmission dynamics and interdependencies, and get a more comprehensive picture of food price shocks propagation. We found significant between‐country market contagion and prompt regional price shock propagation when trade connection exists. Yet, the integration of SSA domestic maize markets within the continent and with global markets remains generally weak. Furthermore, under regular market conditions, most local price series appear to be more responsive to regional neighbors than to global shocks.     

Evaluating price transmission between global agricultural markets and consumer food price indices in the European Union

This paper uses error correction models to evaluate the extent to and speed at which world agricultural commodity price movements affect consumer food prices in the European Union member states. We consider three types of world commodity price indices, each containing different commodities and weighting criteria. Results reveal a long‐run relationship between world agricultural commodity and consumer food prices in over half of the member states. Consumer prices in different member states and categories of member states respond differently to specific world price indices, suggesting that there are disparities in the structure and the efficiency of their food markets. The eurozone founders generally have lower transmission elasticities. This should be taken into account when predicting the impacts of extreme world price volatility and consumer food price rises, prompting governments to pay attention to the most vulnerable households.     

Animal disease outbreaks and food market price dynamics: Evidence from regime‐dependent modelling and connected scatterplots

The economic impacts of animal disease outbreaks have been widely discussed in the literature. Most authors have centred their attention on estimating the direct costs. Recent studies have shown that the indirect economic effects might lead to equal or even higher welfare losses. This study aims to contribute to this field of research by assessing the effect of an animal disease outbreak on food market price dynamics in Mexico, accounting for the potential effect of an antitrust intervention. We employ a regime‐dependent vector error correction model and a connected scatterplot analysis. The results show that both the outbreak and the antitrust intervention caused structural breaks in food market price dynamics between producers and consumers, reflected in an increase in the absolute component of the marketing margin, with serious food security implications.     

Resource abundance,financial crisis and economic growth: did resource‐rich countries fare better during the global financial crisis?

This study examines the role of resource abundance in the cross‐country differences in the impacts of the global financial crisis (GFC) of 2008–2009. Using forecasts from the unobserved components model and exponential smoothing technique, we estimate the output levels a country would reach in 2009 and 2013 in the absence of the GFC, and compare these with the realised output levels. We find large variations in the output losses across 72 countries. The mineral‐rich countries have been found to be in a strong position to survive any adverse shocks stemming from the GFC. Income per capita, trade openness, and institutional quality and government effectiveness are also found to be key factors determining the differences in output loss in the post‐crisis period. These findings have strong implications for resource‐rich countries such as Australia and are expected to shed new light on alternative policy designs and appropriate strategies to deal with any future economic crisis.
