RESUMEN
Background: This study investigates the impact of price changes on decision to buy particular foods among adults in Surabaya, East Java, Indonesia. Tax and subsidy were introduced for influencing decision buy particular foods, especially unhealthy foods that are predicted have consequences on health outcome. Unhealthy foods such as fast foods or junk foods, sugar sweetened beverages (SSB), salty, and fatty foods are reported as one of main causes of obesity incidence in most countries, such as Indonesia. Design and method: Computer laboratory experimental is designed for investigating the impacts of difference rates of taxes and subsidy on decision to buy foods. Taxes and subsidies rate are designed from low (5%), moderate (15%), and high rates (25%). Results: The findings are as follows. Firstly, participants do not respond immediately to price changes, that is, higher prices due to taxes and lower prices due to subsidies. Economic theory suggests that consumers demand for basic need such as foods is sensitive with change in price, they respond inversely to the price changes. However, the finding in this experimental study do not support this theory prediction. Secondly, 15% and subsidies are the threshold and the larger taxes and rate for changing consumer's choices on targeted foods. Conclusion: This study concludes that low rates of taxes and subsidies for unhealthy and healthy foods make these targeted foods affordable for majority of consumers. Besides introducing higher rates of taxes and subsidies, promoting and encouraging healthy life style such as consuming fresh and healthy foods is another alternative policy option.
RESUMEN
The opening of the Indonesian Trade Promotion Center is one of the policies implemented by the government to increase Indonesia's non-oil and gas exports. However, fluctuations in the value of non-oil exports make the role of the ITPC doubtful. This study aims to analyze the impact of Indonesia Trade Promotion Center as Export Promotion Agency (EPA) on the value of Indonesia's non-oil and gas exports globally, to developing countries, and developed countries from 2000 to 2018. The method used in this study is the Random Effect Model and gravity model. Estimation results show that EPA Indonesia (ITPC) has a positive and significant effect on the value of Indonesian non-oil exports in all models. Foreign direct investment (FDI) has a positive effect and significant for global and developing countries model. GDP per capita and Free Trade Agreements have a significant positive effect on non-oil exports in all models. The geographical distance variable has a negative impact for Indonesian non-oil exports in all models, except for the developed countries model.
RESUMEN
This paper tests whether economic growth and unemployment rates matter in the re-election of incumbent district leaders in Indonesia. Applying the Probit and Hekcprobit model on Indonesia's local direct elections during 2005-2013, we find that both unemployment and GDP per capita growth has an impact on election outcomes in the election year. However, for incumbent district leaders' it is only the average annual GDP per capita growth that matters for re-election. However, when we separate luck (district's performance due to regional or national economy) from competence (district's own economic performance), we find that competence matters for re-election in the election year, while luck matters for re-election in the average annual performance of the incumbents' tenure. The findings suggest that voters put more attention and vigilance on the incumbents' performances in the last year of their tenure, rather than on their whole tenure.
