The Disparate Effects of Strategic Manipulation
When consequential decisions are informed by algorithmic input, individuals
may feel compelled to alter their behavior in order to gain a system's
approval. Models of agent responsiveness, termed "strategic manipulation,"
analyze the interaction between a learner and agents in a world where all
agents are equally able to manipulate their features in an attempt to "trick" a
published classifier. In cases of real world classification, however, an
agent's ability to adapt to an algorithm is not simply a function of her
personal interest in receiving a positive classification, but is bound up in a
complex web of social factors that affect her ability to pursue certain action
responses. In this paper, we adapt models of strategic manipulation to capture
dynamics that may arise in a setting of social inequality wherein candidate
groups face different costs to manipulation. We find that whenever one group's
costs are higher than the other's, the learner's equilibrium strategy exhibits
an inequality-reinforcing phenomenon wherein the learner erroneously admits
some members of the advantaged group, while erroneously excluding some members
of the disadvantaged group. We also consider the effects of interventions in
which a learner subsidizes members of the disadvantaged group, lowering their
costs in order to improve her own classification performance. Here we encounter
a paradoxical result: there exist cases in which providing a subsidy improves
only the learner's utility while actually making both candidate groups
worse-off--even the group receiving the subsidy. Our results reveal the
potentially adverse social ramifications of deploying tools that attempt to
evaluate an individual's "quality" when agents' capacities to adaptively
respond differ.Comment: 29 pages, 4 figure
Curriculum reform in UK economics: A critique
This paper offers a multi-dimensional critique of recent reforms to UK Economics curricular frameworks. The paper assesses the reforms in terms of their extent and the positions taken within them on their approach to economics, treatment of politics, and, crucially, educational philosophy. Despite claims of innovation and new epistemological caution in the wake of the global financial crisis, the reforms are found to be minor and superficial. The CORE programme and the revised Subject Benchmark Statement document for Economics still ignore educational philosophy; yet they are implicitly educationally instrumental and remain limitedly pluralist. Our conclusions are buttressed by contrasts made between UK reforms and the curriculum architecture found in the Brazilian system
Whither political economy? Evaluating the CORE project as a response to calls for change in economics teaching
This article offers a critique of a major recent initiative in economics teaching: the CORE project. CORE emerged in the wake of the global financial crisis, which was also something of a crisis for economics. The article deploys four evaluative criteria to pose four questions of CORE that address the demands of the student movement. CORE claims to be innovative and responsive to criticism. However, the article concludes that its reforms are relatively minor and superficial. CORE, like curricula that preceded the global financial crisis, still exhibits limited pluralism, ignores power and politics, and ignores key educational goals. Despite its opportunity to do so, CORE has not opened up space within economics for the teaching of political economy
CHAMP - Chippewa Homestead Antenna & Mission Program
On January 28, 2021 the Michigan Aerospace Manufacturing Association (MAMA) announced the site selection for the Michigan Launch Initiative (MLI) Satellite Command and Control Communications (C3) center. The Chippewa Homestead Antenna & Mission Program (CHAMP) was selected to host, implement, and conduct the C3 functions for MLI\u27s vertical and horizontal launch capabilities. This poster presents in detail the CHAMP phased implementation strategy to support the complex mission operations needs of the next generation Hybrid Architectures and Mesh Networks
