We propose a protection framework for resource sharing to promote cooperation among nodes in multi-hop wireless networks. In the resource sharing protocol, a node claims credits when it relays others’ packets. A node also issues rewards to the node which relays its packets. Rewards are used to validate the correctness of credits. In order to protect credits and rewards, we devise a secure regis...

Regardless of the approach taken, tax credit policies must address risk selection issues to ensure coverage for the chronically ill. Proposals that link tax credits to purchasing pools would avoid risk selection by grouping risks similar to the way large employers do. Volun...

Several studies have suggested that geostatistical techniques could be employed to reduce overall transactions costs associated with contracting for soil C credits by increasing the efficacy of sampling protocols used to measure C-credits. In this paper, we show how information about the range of spatial autocorrelation can be used in a measurement scheme to reduce the size of the confidence in...

A dividend imputation tax system provides shareholders with a credit (for corporate tax paid) that can be used to offset personal tax on dividend income. This paper shows how to infer the value of imputation tax credits from the prices of derivative securities that are unique to Australian retail markets. We also test whether a tax law amendment that was designed to prevent the trading of imput...

Child Care Assistance: Are Subsidies or Tax Credits Better? We evaluate price subsidies and tax credits for child care. We focus on partnered women’s labor supply, household income and welfare, demand for formal and informal child care and government expenditure. Using Australian data, we estimate a joint, discrete structural model of labor supply and child care demand. We introduce two methodo...
