Do oil price changes really matter to the trade balance? Evidence from Korea-ASEAN commodity trade data

The contribution of this article is to assess the effect of oil prices have on the trade balance in the framework of bilateral commodity trade data between Korea and each of the four ASEAN member countries—Indonesia, Malaysia, Singapore, and Thailand. To examine this subject thoroughly, we first assume the effects of oil price changes to be symmetric and apply the linear autoregressive distributed lag (ARDL) method to the subject. We find that the price of crude oil indeed has an important role in affecting Korea's trade balance with those four ASEAN economies in both the long- and short-run. We then separate oil price hikes from oil price plunges and implement the nonlinear ARDL method to reveal that there is evidence that changes in oil prices appear to have asymmetric effects on the trade balance for certain products in the long- and short-run.     

Assessing the Exchange Rate Sensitivity of U.S. Bilateral Agricultural Trade

This paper uses an autoregressive distributed lag approach to cointegration to examine the short- and long-run effects of exchange rate changes on bilateral trade of agricultural products between the United States and its 10 major trading partners. Results show that, in the long run, while U.S. agricultural exports are highly sensitive to bilateral exchange rates and foreign income, U.S. agricultural imports are mostly responsive to the U.S. domestic income. In the short run, on the other hand, both the bilateral exchange rates and income in the United States and its trading partners are found to have significant impacts on U.S. agricultural exports and imports.
Dans le présent article, nous avons utilisé un modèle autorégressif à retards échelonnés (autoregressive distributed lag (ARDL) approach to cointegration) pour examiner les effets à court et à long terme des variations de taux de change sur le commerce bilatéral des produits agricoles entre les États-Unis et ses dix principaux partenaires commerciaux. Les résultats ont montré que, à long terme, bien que les exportations agricoles des États-Unis soient très sensibles aux taux de change bilatéraux et au revenu étranger, les importations agricoles des États-Unis sont principalement sensibles au revenu intérieur des États-Unis. À court terme, par contre, les taux de change bilatéraux et le revenu des États-Unis et de ses partenaires commerciaux ont des répercussions considérables sur les exportations et les importations agricoles des États-Unis.     

Death imagery in antipoaching advertising

In three studies, death imagery and regulatory focus are examined for their effects in wildlife protection campaigns. Images of death are found to lead to positive intentions to conserve wildlife through fear, but only when ads are prevention-focused rather than promotion-focused. In Study 1, participants who view an image of a dead elephant indicate feeling fear and stronger intentions to conserve wildlife. In Study 2, participants who view a prevention-focused ad depicting a dead rhino indicate stronger intentions to sign a wildlife conservation pledge, but the effect is attenuated when the ad is promotion-focused. Study 3 finds similar results using the image of a dead tiger. Theoretical insights and practical implications are discussed.     

Do types of foreign capital matter for income equality?

We investigate the link between financial integration and income inequality, suggesting that different channels of financial integration have contrasting distributional effects. Using an unbalanced panel of 65 countries from 1992 to 2015 and employing dynamic panel data methods, we find that greater financial integration through debt-creating capital increases income inequality compared to equity-type capital. Furthermore, a larger share of direct investment in financial integration is associated with lower income inequality; the converse is true for loans and credit, while the share of portfolio investment has no significant effect when considered as a whole. Evidence also shows that increased financial integration and trade is beneficial for reducing the income inequality of emerging economies.     

On the Determinants of Surges and Stops in Foreign Loans: An Empirical Investigation

This paper examines the determinants of surge and stop episodes in foreign loans using quarterly data from 55 countries covering 1990Q1 to 2011Q4. The estimation results show that, first, global, contagion and domestic factors are all significantly associated with both loan-led surge and stop episodes. Second, domestic factors are more relevant to stops than to surges and are associated more strongly with episodes in emerging countries than with those in advanced countries. Third, global risk and domestic growth shock are most consistent and important in predicting both types of episodes. Fourth, financial linkage is the most important contagion channel in the occurrence of loan-led episodes. Fifth, capital control is not a useful tool for avoiding either type of episode and may actually increase their likelihood. Finally, stops in emerging countries are strongly related to macroeconomic fundamentals such as inflation, current account balance, net foreign assets, real exchange rate, and previous occurrence of surge episodes. Our results strongly suggest that emerging countries with lower institutional quality levels are more likely to experience both surges and stops.     

Are Female Executives More Risk-Averse than Male Executives?

It is often argued that women are more risk averse than men. This paper provides additional evidence on this issue by examining the stock selling behavior of male and female executives in response to stock option awards. When corporate executives sell shares of their firm upon new stock option awards, it is an indication that they are attempting to reduce risk through diversification of their personal portfolio. More rigorous stock sales by female executives would indicate that they are more risk averse than their male counterparts. However, this paper finds that male executives are more risk averse by engaging in higher diversification-related stock sales than the female executives. It is also found that the stock sales by male executives approximate the optimal hedge ratio.     

Food choice,nutrition education and parental influence on British and Korean primary school children

The nutritional status of children can influence their health and the risk factors for developing chronic diseases later in life. Korea is unique in that it is relatively westernized and yet maintains much of the traditional foods and cooking methods. Effective nutrition education should help children to choose a healthy diet through the establishment of positive dietary practices and habits. The main purpose of this research is to compare awareness towards nutrition education between primary schools in the UK and Korea and nutritional knowledge that children and parents have in these countries. Dietary and healthy eating knowledge data were collected by a questionnaire as part of a case study comparison using one primary school in Manchester, UK, and one in Seoul, Korea. A total of 171 primary school children and 124 parents of the children were recruited. The results indicated that children and parents appeared to be aware of the importance of limiting fat, sodium and sugar intakes, and requiring non‐starch polysaccharide (NSP). However, in the case of some foods they did not have satisfactory nutritional knowledge of which foods were high in fat, salt, sugar and NSP. British children had a better understanding of the health implication of fat than Korean children, whereas more Korean children considered excessive salt intake harmful than British children. There seemed to be differences in dietary pattern and familiarity with food between the two countries. Children identified parents as the main source of nutritional information. Therefore, parents as well as children need to learn about nutrition in order to give appropriate information or advice to improve the diets of their children. Children preferred exciting, fun, positive and a practical approach to learning about nutrition, such as computer packages and cookery classes. Parents wanted schools to give their children more information about nutrition. This research has shown that nutrition education in schools should be concerned not only to provide nutritional knowledge but also to encourage children to choose healthy food by redesigning nutrition education and school meals.     

International trade and macroeconomic dynamics: The case of U.S. bilateral trade with G-7 countries

The short- and long-run effects of exchange rates, income, interest rates and government spending on U.S. bilateral trade with the other G-7 countries are investigated using an autoregressive distributed lag (ARDL) model. The primary contribution of this study is to consider separating the analysis of exports and imports in an integrated model that empirically encompasses four major schools of thoughts – elasticity, Keynesian income, absorption and monetary approaches – in order to identify macroeconomic linkages to U.S. bilateral trade with the other G-7 countries accurately. Results suggest that, in both the short- and long-run, U.S. imports and exports are highly sensitive to changes in U.S. and foreign income, while U.S. imports and exports are relatively insensitive to changes in bilateral exchange rate. It is also found that both exports and imports are more responsive to changes in government spending than changes in interest rates in both the short- and long-run.
