We explicitly consider strategic interaction between governments to study currency competition and its effects on the circulation of currencies and welfare in a two-country twocurrency search theoretic model. Each government finances public goods by means of seigniorage. Compared with a regime with two local currencies, a regime with one international currency allows the issuer of the internati...

The Lévy Libor or market model which was introduced in Eberlein and Özkan (2005) is extended to a multi-currency setting. As an application we derive closed form pricing formulas for cross-currency derivatives. Foreign caps and floors and cross-currency swaps are studied in detail. Numerically efficient pricing algorithms based on bilateral Laplace transforms are derived. A calibration example ...

BACKGROUND Transmission of human pathogens can be occurred via inert objects. Paper currency is a further common contact surface whereby pathogens can be transferred within a population although the significance remains unknown. Hence, the aim of the present study was to investigate microbial populations associated with Iranian paper currency. METHODS This study was carried out by getting 108...

This paper develops a firm-dynamics model with heterogenous firms and endogenous currency debt composition to jointly study financing and investment decisions in developing economies. In our model, foreign currency borrowing arises from a trade-off between aggregate deviations from the risk-free uncovered interest rate parity and firms’ growth potential. Crucially, there is crosssectional heter...

Bangladesh is a densely populated agricultural country with an acute shortage of dairy milk. There are about 24.5 million cattle in Bangladesh, of which about 10 million are breeding cows. They provide mainly milk, meat, draught power, transport, and hide (an important export item). Dairying is practiced in Bangladesh as a part of local crop livestock farming systems, typically involving one or...

The present paper analyzes the existence of a long-run relationship between the trade balance and exchange rate of Iran and South Korea by a new approach. It proposes an asymmetric co-integrating NARDL model by two positive and negative partial sum decompositions which can use mixed I (0) and I (1) variables by bounds testing approach. The proposed tests are based on calculated F –statistics an...

Security: Forging paper currency is difficult. Unfortunately, electronic currency is just data and is easily copied. Copying or double spending of electronic currency should be prevented or detected. Ideally the illegal creation, copying, and reuse of electronic cash should be unconditionally or computationally impossible. Some systems rely instead on post-fact detection and punishment of doubl...
