Policy analysis from first principles

Policy analysis from first principles.

The argument of this paper is predicated on the view that social science should start with observation and the specification of a problem to be solved. On that basis, the appropriate properties and conditions of application of relevant tools of analysis should be defined. Evidence is adduced from data for sales volumes and values of a disparate range of goods to show that frequency distribution...

Central Bank Policy: Some First Principles

Counterfactual Causality from First Principles?

In this position paper we discuss three main shortcomings of existing approaches to counterfactual causality from the computer science perspective, and sketch lines of work to try and overcome these issues: (1) causality definitions should be driven by a set of precisely specified requirements rather than specific examples; (2) causality frameworks should support system dynamics; (3) causality ...

Energy decomposition analysis of metal silicide nanowires from first principles

We investigate the structure, stability, and electronic properties of yttrium silicide nanowires with AlB2-type structure, using ab initio calculations. The results confirm experimental findings that yttrium silicide nanowires are robust and conductive. In particular, the dependencies on nanowire thickness are analyzed. Furthermore, calculations show that the vacancy formation in stoichiometric...

Exciton multiplication from first principles.

Third-generation photovolatics require demanding cost and power conversion efficiency standards, which may be achieved through efficient exciton multiplication. Therefore, generating more than one electron-hole pair from the absorption of a single photon has vast ramifications on solar power conversion technology. Unlike their bulk counterparts, irradiated semiconductor quantum dots exhibit eff...
