The number of independent countries has almost tripled since World War II: in 1946 there were 76 independent countries; today there are 193. Until recently, most countries had their own currencies. Hence, the expansion of the number of countries led to a proliferation of the number of currencies. More recently, however, the identification of currencies with countries has weakened, and the discu...

Despite the increasing acceptance and usage of Online Social Networks (OSN), particularly the currency of user data has been identified as a crucial success factor for both, users as well as providers. However, while research on Data Quality (DQ) in traditional information systems is considered to be relatively mature, findings from prior research on currency have not yet been confirmed for the...

In January 1999, members of the European Union introduced a single currency, the Euro. In 2002, the Euro will replace national currencies, and each country’s currency will cease to exist. It is our belief that within the next ten years the Euro will merge with the Dollar to create a single currency for the United States, Europe, and eventually for other countries. These articles explore the imp...

I examine, in a controlled, experimental laboratory setting, the acceptance of a secondary currency when a primary currency already circulates in an economy. The underlying model is an indivisible good / indivisible money, dual currency search model similar to that in Kiyotaki and Wright (1993) and Craig and Waller (2000). In such models, there are two pure Nash equilibria total acceptance or t...

In modelling bumble bee foraging, net rate of energetic intake has been suggested as the appropriate currency. The foraging behaviour of honey bees is better predicted by using efficiency, the ratio of energetic gain to expenditure, as the currency. We re-analyse several studies of bumble bee foraging and show that efficiency is as good a currency as net rate in terms of predicting behaviour. W...

Market participants’ risk attitudes, wealth and portfolio composition influence their positions in a pegged foreign currency and, therefore, may have important effects on the sustainability of currency pegs. We analyze such effects in a global game model of currency crises with continuous action choices, generating a rich set of theoretical comparative static predictions related to often discus...

At the end of the experiment, you will receive a show-up fee of NT$100 plus the NTD converted from the “Standard Currency Units” you have earned in the experiment. (“Standard Currency Units” are the experimental currency units used in the experiment.) The amount of “Standard Currency Units” you will receive, which will be different for each participant, depends on your decision, the decision of...

Using sovereign CDS spreads and currency option data for Mexico and Brazil, we document that CDS spreads covary with both the currency option implied volatility and the slope of the implied volatility curve in moneyness. We propose a joint valuation framework, in which currency return variance and sovereign default intensity follow a bivariate diffusion with contemporaneous correlation. Estimat...

This study evaluated the properties of adhesion, cracking, rusting, and accumulated irradiance on surface four vinyl acrylic resin coatings. QUV accelerated aging technique was applied. The coatings in cyclic form controlled by tests atmospheric temperature relative humidity. A paper money currency validator counterfeit has been used because its constant 1,41 mW/cm2; a power 9 W UV radiation; 2...
