â â â â â â â â â â â  â  abstract â  the foreign exchange market (fx market) accounts for 40% of the total volume of the world’s e-commerce by its own. based on statistics, sometimes up to 90 per cent of the traders lose their total capital in this market just within six months to one year and leave this market. the probability of loss in the fx market can be estimated by probability theory....

Combining total energy and structure optimization calculations, we explored new possible crystalline phases of covalently bonded C60 fullerenes and determined their structural, elastic, and electronic properties. Motivated by reported observations that bulk structures of polymerized fullerenes may be stiffer than diamond, we have explored possible ways of fullerene polymerization and have ident...

the major challenge facing iranian economy is its overwhelming dependence on the oil exports. however, the world oil price has been subject to a lot of shocks, which have destabilized the iranian terms of trade. hence, this paper empirically examines the effect of terms of trade volatility on iran’s economic growth over 1967-2006. for this purpose, based on a garch model, a proxy for the terms ...

in this research at the first, xylometazoline hydrochloride drug (xy) and its fullerene connected form (fxy) were optimized. natural bond orbital (nbo) calculations for these compounds were carried out at the b3lyp/6-31g* quantum chemistry level, in the gas phase and the liquid phase. these calculations can be performed at different accuracy levels depending on the aim of the theoretical study....

This paper examines the exporting behaviour of Russian manufacturers by considering the interaction of firm characteristics and external conditions. An important distinction is made between general exporting activity and export to developed countries. Firm features and specific export experience are found to be important in determining the international orientation of manufacturers and the dest...

Article history: Received 17 August 2014 Received in revised form 16 February 2015 Accepted 30 March 2015 Available online 17 April 2015 This paper examines the asymptotic dependence between the Chinese stock market and the world crude oil market based on the Extreme Value Theory (EVT) and finds a positive extremal dependence. We explain this positive dependence in terms of economic cycles due ...

Immigrant Participation in Social Assistance Programs* The share of foreigners in the German social assistance program exceeds their population share and continues to grow. This study tests whether higher foreigner welfare dependence is due to foreign-native differences in behavior as opposed to exogenous characteristics. The determinants of welfare dependence are analyzed using data from the G...

modeling dependence structure in financial economics is of paramount importance when estimating portfolio’s value at risk, since risk of an asset in addition to its own behavior is also dependent on the behavior of other assets in the portfolio. application of joint distribution copula is one of the methods for incorporation dependence at lower and upper tail of returns’ distribution in financi...

This note explores the analogy between the dynamics of the interest rate term structure and the implied volatility surface of a stock. In particular, we prove an impossibility theorem conjectured by Steve Ross.

Long memory in volatility is a stylized fact found in most ̄nancial return series. This paper empirically investigates the extent to which interdependence in emerging markets may be driven by conditional short and long range dependence in volatility. We ̄t copulas to pairs of raw and ̄ltered returns, analyse the observed changes in the dependence structure may be driven by volatility, and discu...
