TINJAUAN KRITIS TERHADAP KEBIJAKAN HARGA GABAH DAN BERAS DI INDONESIA

<p>The government intervened unhulled rice and rice price policies which requires a large budget and is faced by a trade off between protecting producers and consumers. There is also a rice trading system that has an interest in creating profits. This condition creates obstacles in achieving policy objectives. Objectives of this paper are (1) to analyze the effectiveness of unhulled rice and rice price policies and factors that affect policy effectiveness, (2) to formulate policy recommendations in minimizing side effects. Analysis using secondary data and literature review methods. Results showed that with support of other rice policies, price policy has achieved its goal of stabilizing prices and supporting economic stability. However, it is not yet effective enough to protect farmers' income, affordability of rice prices, and safeguard government rice reserves. Pricing policies need to be carried out selectively with a clear target date and be accompanied by policy instruments for farmer income and food consumption flexibility, as well as encouraging farmer independence. Farmers can be facilitated to choose profitable commodities supported by an information system, market access, credit policies, <em>input</em> subsidies and agricultural infrastructure such as irrigation.</p>

Econometric Analysis of Residential Sector Gas Demand Elasticities in Gas Exporting Countries

This paper examines how residential sector gas demand in gas exporting countries response to changes by taking into consideration the economic variables. For this purpose, the short and long-run price and income elasticities of residential sector gas demand in the GECF countries for 2000 and 2019 are measured. Using Cobb-Douglas functional form, this paper applies the bounds testing approach to co-integrate within the framework of ARDL (Autoregressive Distributed Lag). Findings of this research show that there is a significant long-run relationship in nine GECF countries, including Algeria, Egypt, Iran, Malaysia, Norway, Peru, Russia, Trinidad and Tobago and Venezuela, that use gas as a source of energy in their residential sector. On average, long-rung income elasticity for underlying countries is 2.65, while long-run price elasticity is negative and calculated at 0.79. This shows that in considered gas exporting countries, residential sector gas demand is very sensitive to income policies, while the price policies impact on demand is more limited. Furthermore, short-run income and price elasticities are estimated at 6.99 and -0.02 (near zero) respectively, which implies that natural gas is very inelastic to price, as a result,price policies are unable to make significant changes in demand over the short-term. Meanwhile, as expected short-run price elasticity is lower than long-run elasticities, indicating that gas exporting countries are more responsive to price in the long-term than in the short-term. Finally, it was found that most of the preferred models have empirical constancy over the sample period.&nbsp;

The impacts of fuel price policies on air pollution: A case study of Tehran

Background: This study aims to investigate the impacts of fuel price policies on the concentration of air pollutants emitted from the transport sector.Methods: Autoregressive distributed lag (ARDL) estimation models were used to investigate the impacts of gasoline and diesel prices along with the weather and economic variables on the following traffic-related pollutants: Carbon monoxide (CO), Nitrogen dioxide (NO2), and Particular matter 10 micrometers or less (PM10).Results: In the short term, one percent increase in gasoline prices leads to 0.02 and 0.012 percent decrease in the concentration of CO and PM10, respectively. In addition, in the short term, one percent increase in diesel prices leads to 0.008, 0.02, and 0.015 percent decrease in the concentration of CO, PM10, and NO2, respectively. Results demonstrate that one percent increase in gasoline prices leads to 0.011 and 0.02 percent increase in NO2 concentration in the short term and long term, respectively. Fuel prices had a greater impact on air pollutant concentration in the long term than in the short term. In the long term, one percent increase in diesel prices leads to 0.011, 0.024, and 0.029 percent decrease in the concentration of CO, NO2, and PM10, respectively.Conclusion: Although fuel price increases lead to a significant reduction in air pollution concentration, other factors related to weather conditions (wind speed, temperature, and rainfall) as well as economic activities have a greater impact on air pollution. Therefore, other policies such as improving fuel quality and technology along with other economic policies can be more effective.
