We study the development of conjunctive keyword searchable scheme which enables one to search encrypted documents by using more than one keyword. The notion of conjunctive keyword searching was presented by Golle et al. in 2004. However, their security model was constructed in a symmetric-key setting which is not applicable for the overall applications in the reality. So Park et al. extended Go...

In this paper we present several proofs on the extension of M. Riesz fractional integration and di¤erentiation to the contexts of spaces of homogeneous type and measure metric spaces with non-doubling measures. 1. Introduction, some de…nitions, and a basic lemma Professor M. Ash asked me to write a survey article on some of the results that Stephen Vági and I obtained in the nineties on fractio...

In this paper, tests are made for the effect that the spatial distribution of welfare and Food Stamp caseloads may have on caseload change in the South. Spatial effects are captured by contrasting caseload trends overtime in metropolitan (urban) counties and nonmetropolitan (rural) counties within two southern states, Mississippi and South Carolina. Tests for a location effect on caseload chang...

Incentives and Welfare Effect of Sharing Firm-Specific Information by Jim Y. Jin* This paper studies the incentives and the welfare effect of sharing firm-specific information in asymmetric Cournot and Bertrand oligopoly with mixed substitute and complement goods.

The links between Medicaid and welfare exits are examined using longitudinal Medicaid program data. Few people who leave welfare get any sort of ongoing or transitional Medicaid protection. Moreover, it appears that many who are eligible for transitional benefits are not getting them. Finally, people with high expected medical costs appear to be less likely to leave welfare. The loss of Medicai...

The equivalent variation and the compensating variation, introduced by John R. Hicks (1939), are used in demand theory to monetize the effect of a given welfare change on a consumer. The compensating variation C corresponds to the consumer’s willingness to pay (WTP) to effectuate the welfare change, while the equivalent variation E measures the consumer’s willingness to accept (WTA) to reverse ...

The Transition from Welfare to Work and the Role of Potential Labor Income It is often argued that the high level of welfare claims in Germany causes little incentive for workers with low productivity to seek for a job. We examine the influence of the ratio between estimated potential labor income and the welfare payment level on the probability of leaving social welfare. Using the GSOEP, we es...
