Using climate models to improve Indonesian food security   总被引:1,自引:0,他引:1  
El Niño Southern Oscillation (ENSO) events exert significant influence on Southeast Asian rice output and markets. This paper measures ENSO effects on Indonesia's national and regional rice production and on world rice prices, using the August Niño 3.4 sea surface temperature anomaly (SSTA) to gauge climate variability. It shows that each degree Celsius change in the August SSTA produces a 1,318,000 metric ton effect on output and a $21/metric ton change in the world price for lower quality rice. Of the inter-annual production changes due to SSTA variation, 90% occur within 12 provinces, notably Java and South Sulawesi. New data and models offer opportunities to understand the agricultural effects of ENSO events, to reach early consensus on coming ENSO effects, and to use forecasting to improve agencies' and individuals' capacity to mitigate climate effects on food security. We propose that Indonesia hold an ‘ENSO summit’ each September to analyse the food-security implications of upcoming climate events.  相似文献

Large areas of Northeast Asia experienced drought in 1939. Agricultural production in Korea decreased significantly, but the drought did not cause famine in Japan despite its dependence on rice imports from Korea. The paper analyses the impact of the 1939 drought on the markets for rice and electricity in Japan. The authorities were ill-prepared for such a disaster but willing to use it for the purpose of covering for other problems. The drought thus accelerated the move of Japan's economic system towards a managed economy. A lower total rainfall in Japan in 1940 did not generate similar problems, suggesting that the broader political, economic, and social context is crucial to the identification of short-term climatic fluctuations as crises.  相似文献

Wheat production stagnated in France during the late nineteenth and early twentieth century, while cultivated acreage and wheat output declined sharply around the Mediterranean from the 1870s. Wheat output never recovered in this region despite the introduction in 1885 of tariff measures, such as the 1892 Méline Tariff. This paper analyses the response of Mediterranean wheat growers to changes in local rainfall and to variations of the duty on imported grains. It uses regional level data for nine administrative divisions located on or near the Mediterranean and assesses the impact of rainfall on yields. It argues that an interplay of protectionist policies and environmental conditions explain the decline of wheat production.  相似文献

In the South African agricultural (specifically grain) markets an interesting phenomenon exists: where futures and options on grain products exist (i.e. white maize, yellow maize, soy beans, wheat, and sunflower seeds) price discovery in the spot (also known as “cash”) markets is poor, whereas price discovery in the futures markets is considered respectable. Consequently, whenever a spot deal is undertaken, this price is “derived” from the relevant futures market. This severely anomalous phenomenon will be evident: futures are generally labeled “derivatives” because their prices are “derived” from their spot markets, whereas here we have a situation where spot prices are derived from their futures price (specifically the price of the near – as opposed to far – future). Because of this unusual phenomenon the mathematics involved is not readily available in the literature; this article is an attempt to briefly outline the phenomenon and to present the relevant mathematics.  相似文献

The paper investigates energy price co-movement over the period 01/1999–12/2005 for China as a whole, and over sub-periods and for seven regions, using panel unit root and panel cointegration tests developed by Pedroni (1999, 2004). The results suggest that not all energy sources are spatially homogenous in prices and the processes of energy price cointegration are different over sub-periods; over groups of fuels; and over regions. Coal and electricity prices have co-moved since 2003 while gasoline and diesel prices have co-moved since 1997. The results show that there are clearly variations in the emergence of energy price co-movement over regions, implying that regional fuel markets have emerged in China. Important lessons that can be learnt from the results are that an energy market has, to some extent, already emerged in China and, as a result, energy prices are substantially less distorted than before. If correct, these findings have significant global implications both in terms of future emission reductions, emission trading and trade negotiations where China should be treated as a ‘market driven economy’.  相似文献

It is well known that intra-industry trade and cross-border production networks have promoted economic growth and regional integration in East Asia. However, regional supply and production chains may have been formed differently across industries, reflecting different degrees and a different scope of regional economic linkages at an industry level. This paper makes a threefold contribution. First, to assess industry-level differences, this study adopts the generalized purchasing power parity (G-PPP) model using industry-specific producer prices. Second, the momentum threshold autoregressive (M-TAR) model is employed to allow for possible nonlinearity arising from the dynamic nature of regional economic growth and development. Third, the Granger causality test is also conducted to assess whether regional economies have autonomously integrated. The empirical results reveal that economic integration has progressed more autonomously in the electrical industry, as well as in the transportation equipment industry, as China and the ASEAN countries have become the final destination markets for finished products in these two industries.  相似文献

Current discussions of climate change are overly focused on the science underpinning environmental impact, with little attention to socioeconomic consequences. The economics of environmental change in particular is insufficiently informed by the lessons that past experiences can yield. Drawing on case studies from Europe and Asia, this special issue underlines the importance of historical context, as well as markets, institutions, technology, and the role of international trade in understanding how economic systems have responded to environmental changes. Past economies have responded dynamically to environmental change rather than simply constrained deterministically by the climatic and ecological events that have engulfed them.  相似文献

This paper examines differences in the spatial and temporal variations of rice yields in China and Brazil. Our analysis indicates that, in China, rice yields have converged over time and rice production has become increasingly homogeneous. In contrast, rice yields in Brazil have diverged over time, primarily due to variations in upland rice yields. Three hypothetical explanations may account for the different behaviors of rice yields in Brazil and China, namely: 1) differences in production systems (i.e. irrigated in China vs. upland in Brazil); 2) changes in rainfall patterns; and 3) bias in agricultural research and development (R&D) towards irrigated rice. Our empirical analysis supports the first two hypotheses by establishing that: 1) upland rice shows much more variation in yields compared to irrigated rice; and 2) changing rainfall patterns have primarily affected upland rice. We also provide evidence of the bias towards irrigated systems by looking at the patterns of varietal release.  相似文献

Spot to retail price pass-through behavior of the U.S. gasoline market was investigated at the national and regional levels, using weekly wholesale and retail motor gasoline prices from January 2000 to the present. Asymmetric pass-through was found across all regions, with faster pass-through when prices are rising. Pass-through patterns, in terms of speed and time for completion, were found to vary from region to region. Spatial aggregation was investigated at the national level and the East Coast with the aggregated cumulative pass-through being greater than the volume-weighted regional pass-through when spot prices increase. These results are useful to the petroleum industry, consumers, and policy makers by providing a basis to estimate the retail price effects that result from a change in spot price.  相似文献

Despite the impact of El Niño-Southern Oscillation (ENSO) events on climate in the Indo-Pacific region, models linking ENSO-based climate variability to Indonesian cereal production are not well developed. This study measures connections among sea-surface temperature anomalies (SSTAs), rainfall, and Indonesian rice and corn production from 1971 to 1998. Year-to-year August SSTA fluctuations explain about half the interannual variance in paddy production during the main (wet) season. These effects are cumulative for rice: during strong El Niño years, wet season production shortfalls are not made up subsequently. For corn, the cumulative area sown is actually higher in El Niño years than La Niña years. Indonesia's paddy production varies on average by 1.4 million tons for every 1°C change in August SSTAs. The paper illustrates how an SSTA model might assist policy makers with budgetary processes, and private sector cereal traders with framing production expectations.  相似文献

Housing markets and the economy: the assessment   总被引:3,自引:0,他引:3  
Housing markets have multiple interactions with the rest ofthe economy and these are surveyed in this paper. The driversof house prices include income, the housing stock, demography,credit availability, interest rates, and lagged appreciation,the latter a potential mechanism for overshooting. There israther less agreement on the determinants of new construction,though planning constraints are widely seen as a major issueand one of the causes of the UK housing affordability problem.The paper argues that housing collateral and downpayment constraintsare the key to understanding the role of house-price variationsin explaining medium-term consumption fluctuations. Institutionalvariations between countries and over time account for majordifferences in linkages between house prices and economic activity.This illuminates debates about how monetary and other policyshould react to house-price variations. The paper also discussesthe role of housing markets in explaining regional migrationand location decisions, intergenerational inequality, and restrictingaccess of the less affluent to public goods, such as good schools,which are capitalized in local house prices.  相似文献

This study analyses the Ezemvelo Farmers' Organisation (EFO), a certified organic smallholder group in KwaZulu‐Natal province (South Africa), as an institution to improve smallholder access to a niche market by reducing unit production and transaction costs in the supply chain. Using a multinomial logit model, results suggest that EFO is more likely to survive if it continues to secure fully subsidised information, transport, fencing, and certification services for its members, and if it improves the benefits of participating by synchronising harvest and delivery dates, negotiating price discounts for organic inputs, and by maintaining an office with telephone, fax and postal services.  相似文献

The present paper describes the benefits and costs, in qualitative terms, of managing food price instability in Asia in the context of promoting economic growth and poverty reduction to improve food security. The experience of Asian governments in actual practice with price stabilization is discussed in the context of managing an efficient transition to market‐mediated food security. Recent experience in Indonesia, where a sharp increase in rice prices (caused by a ban on rice imports) pushed 4 million people into poverty, provides continued motivation for the analytical story in this paper.  相似文献

Diverse instruments have been used to encourage developing agriculture. In the process, billions of dollars have been spent on providing incentives to peasants. Given scarce resources, an important concern has been the issue of what policy instruments to emphasize. In this regard, useful policy information can be gleaned from the role of expected profits (revenue and input prices), assets (irrigation and infrastructure), and relevant risks, in evoking peasant response. Using panel data for the period 1967/1968 to 1999/2000 pertaining to seven major Indian cash crops cultivated across 14 major states, we find strong evidence of a differential producer response in the post‐liberalization phase, although the important variables per se are much the same. Our results suggest that the preferred policy ought to emphasize availability of irrigation, affordable fertilizer, and rural infrastructure, rather than incessant increases in output prices.  相似文献

This paper examines monthly wage data collected by the Agro Economic Survey from seven villages in the Cimanuk River Basin of West Java, where data on agricultural and non-agricultural wages and prices of nine essential commodities were collected twice monthly between 1977 and 1983. Movements in money wages deflated by both the rice price and a weighted index of basic commodities are analysed in detail and differences between lowland and upland villages are discussed.  相似文献

This article studies the interrelation between spot and futures prices in the two major rice markets in prewar Japan from the perspective of market efficiency. Applying a non‐Bayesian time‐varying model approach to the fundamental equation for spot returns and the futures premium, we detect when efficiency reductions in the two major rice markets occurred. We also examine how government interventions affected the rice markets in Japan, which colonized Taiwan and Korea before the Second World War, and argue that the function of rice futures markets crucially depended on the differences in the structure of rice spot markets. Initially the increased volume of imported rice of a different variety from domestic rice disrupted the rice futures markets. Then, government intervention in the rice futures markets failed to improve the disruption. Changes in colonial rice cropping successfully mitigated the disruption, and colonial rice was promoted in order to unify the different varieties of inland and colonial rice.  相似文献

Price formation provides critical insights into the attributes of fledgling property markets in developing countries. This article investigates asking-price formation across the Indonesian archipelago, including previously unstudied regional property markets. We compile a rich micro dataset of asking prices for residential, commercial, and undeveloped land from a nationwide classifieds database. Through a hedonic price analysis we identify the impact of property and advertisement attributes on asking prices for each type of property, using spatial fixed effects to control for spatially correlated unobservable characteristics at the district and city levels. Results indicate that property characteristics, land ownership status, and advertising method are all statistically significant indicators of asking price. We find considerable heterogeneity in asking-price formation in residential, commercial, and undeveloped land, and identify key differences between urban and rural markets.  相似文献

We analyze empirically export-price strategies across export destinations using detailed firm-product data. Most recent studies using disaggregated data to investigate why firms charge different prices for the same product on different markets focus on the cost component of prices and neglect the markup component. In this paper, we concentrate on the markup component and examine how variations in firms’ export prices may reflect price discrimination by comparing the markup of firms with different pricing strategies. We make use of detailed firm-level data for exporting firms in the Swedish food sector consisting of both manufacturing and intermediary trading firms. The paper documents the export-price variations within the two sub-sectors and explores how different price strategies correlate with markups. The results offer new information beyond the fact that exporters tend to have a higher markup. In particular, we find that firms in the food-processing sector with a greater ability to discriminate across markets mark their products up even more. This result points to the importance of underlying firm decisions in order to explain differences in export premiums across firms. In addition, the results reveal that markups are a complex function of firm and destination characteristics, and that the relationship between markups and pricing strategies in the manufacturing sector is not necessarily observed in other sectors of the supply chain.  相似文献

In this paper we measure the pricing to market for the main export products in the Eurozone automobile industry. Results reveal that significant markup adjustments exist following exchange rate variations. In general, these adjustments allow a strong stabilization of prices in buyer's currency terms. Nevertheless, the degree of pricing to market is quite heterogeneous and differs highly across both product categories and destination markets.  相似文献
