We combine real estate data with various types of crime data using time and geospatial information to detect discontinuities in transaction densities and pricing around crime events in Rochester, NY. Discontinuities in transaction densities invalidate causal inference for price responses implied by the regression discontinuity design (RDD) approach. However, these discontinuities also capture the liquidity response to crimes and, together with the commonly emphasized price response, provide a richer picture of how crime affects housing valuation. A calibrated match-and-bargain model reveals that house valuations decrease between 6% and 25% after a crime, depending on the type of crime. These predictions are manifolds of the estimated effect on prices documented in this paper and in the literature. The welfare effects of crime are not uniform across market participants and can elicit considerable disappointment to uninformed buyers that move into a high-crime neighborhood.
Old age retirement pensions are an important concern among the Swiss but estimating one’s income after retirement is difficult due to the Swiss insurance system’s complexity. This project’s aim is to prepare for developing a digital platform that will allow individuals to plan for retirement in a simplified manner. The main objective of the platform will be togive individuals the tools to check that their savings and retirement benefits will allow them to continue the lifestyle to which they are accustomed once they are retired. The research results from qualitative (focus group) and quantitative (survey) methodologies, recommend the scope and functionalities for a digital platform to be developed. A main outcome is the need to limit the platform’s scope to old-age pension only (excluding survivors’ or disability pensions, for instance). Furthermore, an outcome regarding the functionalities is the proposition of scenarios such as early retirement, changes to income, or modifications to personal status. The development of the digital platform will be a subsequent project.
This paper presents a solution to dismiss a digital evidence from a permissioned blockchain-based legal system, serving as evidence chain of custody. When challenged into court, a digital evidence can be entirely dismissed, as well as all the procedural acts originating from this evidence, including personal gathered data. Since a blockchain, by design, cannot be altered, this paper proposes an alternative solution based on an access control to the blockchain. This solution relies on an additional structure, linked to the blockchain, representing the history and current legal state of the case. Access to the blockchain is controlled by first interrogating this additional structure in order to serve only legally accepted evidence. Therefore, an evidence stored into the blockchain is not destroyed, but is no longer visible nor accessible. Furthermore, evidence data is separated from the blockchain transaction’s payload, that holds only metadata, and this separation reinforces privacy protection. The solution presented in this paper is explainable to all parties to a court trial.
