Resum Cash management is concerned with optimizing costs of short-term cash policies of a company. Different optimization models have been proposed in the literature whose focus has been only placed on a single objective, namely, on minimizing costs. However, cash managers may also be interested in risk associated to cash policies. In this paper, we propose a multi-objective cash management mod...

Recently, Fan et al. proposed a novel e-cash scheme which allows a user to recover the e-cash he lost. They claimed their e-cash possesses properties of anonymity, unlinkability (i.e. untraceability), bank-off-line payment, doublespending detection, and anonymity revocation. The ecash untraceability is greatly related to users’ privacy and indicates that no one including the issuer bank can lin...

Money is important for us since we can use it to purchase the desired goods and services in a convenient and anonymous way. However, carrying paper cash may be a little annoying sometimes, since the paper cash could be stolen by thieves and become a media for bacteria. So, using the existing cryptographic tools and security measures, can we replace paper cash with digital cash? In this lecture,...

In this paper we provide evidence on how firm-specific and macroeconomic uncertainty affects shareholders’ valuation of a firm’s cash holdings. This extends previous work on this issue by highlighting the importance of the source of uncertainty. Our findings indicate that increases in firm-specific risk generally increase the value of cash while increases in macroeconomic risk generally decreas...

Pairs of discrete event time series are characterised by their asynchronous nature, often hampering direct application of otherwise common analysis methods. For correct application of scatter plots, pairs of discrete event time series first have to be pre-processed and merged into a new synthetic time series of so-called coobservations. While standard scatter plots suggest analysis of global st...

This paper analyzes how low-income fathers allocate their resources across complex parenting situations, and why some fathers provide no support at all to their non-custodial children. Data come from the Time, Love, and Cash among Couples with Children (TLC3) project, a longitudinal, qualitative study of 75 romantically involved parents who have just shared a birth. One possible explanation for...

T he 1999 Purdue Land Values Survey indicates that the value of an acre of average bare Indiana cropland was $2,092 per acre in June 1999. This was $63 less than the value reported in June 1998, a 2.9 percent decrease. This decline ends 11 consecutive years of increasing values. Cash rents declined from 1998 to 1999 on average land by a little less than two percent to $110 per acre. This is the...
