Reduction of the mean hedging transaction costs
Miklavž Mastinšek, 2015, izvirni znanstveni članek

Opis: Transaction costs of derivative hedging appear in financial markets. This paper considers the problem of delta hedging and the reduction of expected proportional transaction costs. In the literature the expected approximate proportional transaction costs are customarily estimated by the gamma term, usually the largest term of the associated series expansion. However, when options are to expire in a month or few weeks, other terms may become even larger so that more precise estimates are needed. In this paper, different higher-order estimates of proportional transaction costs are analyzed. The problem of the reduction of expected transaction costs is considered. As a result, a suitably adjusted delta is given, for which the expected approximate proportional transaction costs can be reduced. The order of the mean and the variance of the hedging error can be preserved. Several examples are provided.

Diagonal cumulation of origin as the EU's institutional incentive mechanism for promoting international trade and business
Milan Jurše, Klavdij Logožar, Romana Korez-Vide, 2010, izvirni znanstveni članek

Opis: In this paper we explore the effects of a diagonal cumulation of origin as the EU's Common Commercial Policy (CCP) incentive mechanism that affects the intraregional trade and transaction cost structure of firms engaged in cross-border business operation. The research explores how firms should frame their cross-border physical flows of goods and the configuration of their value-adding processes for taking advantage of diagonal cumulation of origin. The empirical analysis is based on an in-depth case study of effects of the 'SAP+ diagonal cumulation of origin' on changes in the transaction cost structure of a selected Slovenian firm operating within the household-appliance sector in one of the Western Balkan Countries. Based on eligibility of local subsidiary for using origin of goods in its import/exporttransactions the cost calculations were made for its products and then three different business scenarios were developed for showing the effects of the mechanism on transaction cost changes of a firm. The paper concludes that, at the conceptual level, the mechanism of diagonal cumulation of origin may serve as an effective institutional cross-border trade-promoting tool.

Small scale gold mining effects on the miners and local communities in semi-arid region of Ethiopia
Hailemariam Meaza, Mushir Ali, Solomon Hishe, Zbelo Tesfamariam, 2015, izvirni znanstveni članek

Opis: North Ethiopian highlands are traditionally known for gold mining which has been means of livelihood of the rural community. The present work was conducted to investigate socio- economic conditions of gold miners, ways of obtaining the gold, their earning and negative consequences of the gold mining. On the basis of random sampling, 140 miners were interviewed. Moreover, focus group discussions transect walks and practical observations across the mining sites were made with team leaders on different issues of gold mining and its effects. Descriptive statistics was used to compute socio-economic characteristics, gold harvesting, and income dynamics. ANOVA was run to observe variations of income from gold mining and other sources, 2009 to 2012. The positive effects of gold mining for involved people were regarding income, employment, expenditure on education, health and food consumption. On the other hand, conflicting interest, communicable diseases, aggressive child labour, school dropouts, social disruptions and injuries were challenges of the small scale gold mining. The findings highlight that the income generated from small scale gold mining plays a pivotal role in reducing rural poverty. Therefore, providing integrated training for gold miners can mitigate the challenges of small scale gold mining and thereby to improve livelihoods of the small scale gold miners in Ethiopia.
