    Historical perspectives on a program for mathematically talented students

    Get PDF
    The University of Minnesota Talented Youth Mathematics Program (UMTYMP) is a highly accelerated program for students who are extremely talented in mathematics. This paper describes our experiences running UMTYMP since its inception thirty years ago, the challenges in implementing such a program, and how changes in the student body have necessitated changes in the program over three decades

    Designed to fail : a biopolitics of British Citizenship.

    Get PDF
    Tracing a route through the recent 'ugly history' of British citizenship, this article advances two central claims. Firstly, British citizenship has been designed to fail specific groups and populations. Failure, it argues, is a design principle of British citizenship, in the most active and violent sense of the verb to design: to mark out, to indicate, to designate. Secondly, British citizenship is a biopolitics - a field of techniques and practices (legal, social, moral) through which populations are controlled and fashioned. This article begins with the 1981 Nationality Act and the violent conflicts between the police and black communities in Brixton that accompanied the passage of the Act through the British parliament. Employing Michel Foucault's concept of state racism, it argues that the 1981 Nationality Act marked a pivotal moment in the design of British citizenship and has operated as the template for a glut of subsequent nationality legislation that has shaped who can achieve citizenship. The central argument is that the existence of populations of failed citizens within Britain is not an accident of flawed design, but is foundational to British citizenship. For many 'national minorities' the lived realities of biopolitical citizenship stand in stark contradistinction to contemporary governmental accounts of citizenship that stress community cohesion, political participation, social responsibility, rights and pride in shared national belonging

    Evidence and Ideology in Macroeconomics: The Case of Investment Cycles

    Get PDF
    The paper reports the principal findings of a long term research project on the description and explanation of business cycles. The research strongly confirmed the older view that business cycles have large systematic components that take the form of investment cycles. These quasi-periodic movements can be represented as low order, stochastic, dynamic processes with complex eigenvalues. Specifically, there is a fixed investment cycle of about 8 years and an inventory cycle of about 4 years. Maximum entropy spectral analysis was employed for the description of the cycles and continuous time econometrics for the explanatory models. The central explanatory mechanism is the second order accelerator, which incorporates adjustment costs both in relation to the capital stock and the rate of investment. By means of parametric resonance it was possible to show, both theoretically and empirically how cycles aggregate from the micro to the macro level. The same mathematical tool was also used to explain the international convergence of cycles. I argue that the theory of investment cycles was abandoned for ideological, not for evidential reasons. Methodological issues are also discussed

    The War on Poverty after 40 Years: A Minskyan Assessment

    Full text link
    Twenty to 25 years ago, a debate was under way in academe and in the popular press over the War on Poverty. One group of scholars argued that the war, initiated by Presidents Kennedy and Johnson, had been lost, owing to the inherent ineffectiveness of government welfare programs. Charles Murray and other scholars argued that welfare programs only encouraged shiftlessness and burdened federal and state budgets. In recent years, despite the fact that the extent of poverty has not significantly diminished since the early 1970s, the debate over poverty has seemingly ended. In a country in which middle-class citizens struggle to afford health insurance and other necessities, the problems of the worst-off Americans seem to many remote and less than pressing. Moreover, the welfare reform bill of 1996 has deflected much of the criticism of the welfare state by ending the individual-level entitlement to Aid to Families with Dependent Children benefits (now known as Temporary Assistance to Needy Families) and putting time limits on welfare recipiency, among other measures

    The Return of Fiscal Policy: Can the New Developments in the New Economic Consensus Be Reconciled with the Post-Keynesian View?

    Full text link
    The monetarist counterrevolution and the stagflation period of the 1970s were among the theoretical and practical developments that led to the rejection of fiscal policy as a useful tool for macroeconomic stabilization and full employment determination. Recent mainstream contributions, however, have begun to reassess fiscal policy and have called for its restitution in certain cases. The goal of this paper is to delimit the role of and place for fiscal policy in the New Economic Consensus (NEC) and to compare it to that of Post-Keynesian theory, the latter arguably the most faithful approach to the original Keynesian message. The paper proposes that, while a consensus may exist on many macroeconomic issues within the mainstream, fiscal policy is not one of them. The designation of fiscal policy within the NEC is explored and contrasted with the Post-Keynesian calls for fiscal policy via Abba Lerner's "functional finance" approach. The paper distinguishes between two approaches to functional financeone that aims to boost aggregate demand and close the GDP gap, and one that secures full employment via direct job creation - a link that the Post-Keynesian approach promises to restore

    Unemployment: The Silent Epidemic

    Full text link
    This paper examines two key aspects of unemployment-its propagation mechanism and socioeconomic costs. It identifies a key feature of this macroeconomic phenomenon: it behaves like a disease. A detailed assessment of the transmission mechanism and the existing pecuniary and nonpecuniary costs of unemployment suggests a fundamental shift in the policy responses to tackling joblessness. To stem the contagion effect and its outsized social and economic impact, fiscal policy can be designed around two criteria for successful disease intervention-preparedness and prevention. The paper examines how a job guarantee proposal uniquely meets those two requirements. It is a policy response whose merits include much more than its macroeconomic stabilization features, as discussed in the literature. It is, in a sense, a method of inoculation against the vile effects of unemployment. The paper discusses several preventative features of the program

    Bayesian Averaging over Many Dynamic Model Structures with Evidence on the Great Ratios and Liquidity Trap Risk

    Full text link
    A Bayesian model averaging procedure is presented that makes use of a finite mixture of many model structures within the class of vector autoregressive (VAR) processes. It is applied to two empirical issues. First, stability of the Great Ratios in U.S. macro-economic time series is investigated, together with the effect of permanent shocks on business cycles. Second, the linear VAR model is extended to include a smooth transition function in a (monetary) equation and stochastic volatility in the disturbances. The risk of a liquidity trap in the U.S.A. and Japan is evaluated. Although this risk found to be reasonably high, we find only mild evidence that the monetary policy transmission mechanism is different and that central banks consider the expected cost of a liquidity trap in policy setting. Posterior probabilities of different models are evaluated using Markov chain Monte Carlo techniques
