We provide one of the first large sample comparisons of cash policies in public and private U.S. firms. We first show that despite higher financing frictions, private firms hold, on average, about half as much cash as public firms do. By examining the drivers of cash policies for each group, we are able to attribute the difference to the much higher agency costs in public firms. By combining ev...

Recently, some divisible electronic cash (e-cash) systems have been proposed. However, in existing divisible e-cash systems, efficiency or unlinkability is not sufficiently accomplished. In the existing efficient divisible cash systems, all protocols are conducted in the order of the polynomial of logN where N is the divisibility precision (i.e., (the total coin amount)/ (minimum divisible unit...

Untraceability and unreuseability are essential security properties for electronic cash protocols. Many protocols have been proposed to meet these two properties. However, most of them have not been formally proved to be untraceable and unreuseable. In this paper we propose to use the applied pi calculus as a framework for describing and analyzing electronic cash protocols, and we analyze Fergu...

I quantify a new motive of holding cash through the channel of financing risk. I show that if the access to future credit is risky, firms may issue long-term debt now and save funds in cash to secure the current credit capacity for the future. I structurally estimate the model and find that this motive explains about 30% of cash holdings in the data. Counterfactual experiments indicate that the...

Online mobile payment systems based on mobile cash provide privacy to customers and are feasible for real point of sale, virtual point of sale, and person-to-person mobile commerce scenarios. The merchant does not perform complex operations and the bank verifies the validity of the mobile cash before the merchant delivers the product. The bank must store the mobile cash spent in a database to p...

We analyze the risk characteristics and the valuation of assets in an economy in which the investment opportunity set is described by the real interest rate and the maximum Sharpe ratio. It is shown that, holding constant the beta of the underlying cash flow, the beta of a security is a function of the maturity of the cash flow. For parameter values estimated from U.S. data, the security beta i...

We examine whether and how a US cross-listing mitigates the risk that insiders will turn their firm’s cash holdings into private benefits. We find strong evidence that the value investors attach to excess cash reserves is substantially larger for foreign firms listed on US exchanges and over-the-counter than for their domestic peers. Further, we show that this excess-cash premium stems not only...

Abstrac t . We propose a micro-cash technique based on a one-time signature scheme: signing a message more than once leads to disclosure of the signer's private key. In addition to usual cash properties such as off-fine bank for payment and spender's anonymity, the technique also provides a number of useful features. These include: identifying double spender with strong proof, cash revocable fo...

Electronic Invoice Presentment and Payment (EIPP) can assist corporate treasurers in cash management and can be integrated with e-marketplaces and other B2B financial settlement activities. Its interactive approach to dispute resolution and robust payment options are critical if corporate financiers are to secure the advantages of B2B marketplaces and straight through processing (STP). Cash man...

We use China as a laboratory to test the effect of government quality on cash holdings. We build on, and extend, the existing literature on government expropriation and its interaction with firm-level agency problems by proposing a financial constraint mitigation argument. We find that firms hold less cash when local government quality is high, which is not consistent with the state expropriati...
