    Systematic influences on teaching evaluations: The case for caution
    Davies, M ; Hirschberg, J ; Lye, J ; Johnston, C ; Mcdonald, I (WILEY, 2007-03)
    In this paper, we examine eight years of Quality of Teaching (QOT) responses from an Economics Department in an Australian University. This is done to determine what factors, besides the instructor, have an impact on the raw average student evaluation scores. Most of the previous research on student ratings has been conducted in the US. One significant difference between US and Australian tertiary education is that, on average, the number of foreign undergraduate students in Australia is ten times the number in US institutions. We find that cultural background significantly affects student evaluations. Other factors that have an influence on the average QOT score include: year level; enrolment size; the quantitative nature of the subject; the gender of the student; fee‐paying status by gender; course of study; the differences between the course mark and previous marks; the quality of workbooks; the quality of textbooks; and the QOT score relative to those in other subjects taught at the same time. In addition, average QOT scores for instructors who have taught in a mix of subjects are similar to those based on scores adjusted to account for subject and student characteristics.

    The role of portfolio shocks in a structural vector autoregressive model of the Australian economy
    Fry, R ; Hocking, J ; Martin, VL (BLACKWELL PUBLISHING, 2008-03)
    Domestic and foreign equity shocks on the Australian economy are analysed within a five‐variate structural vector autoregressive model, with identification achieved through long‐run restrictions based on the natural rate hypothesis, monetary neutrality, long‐run portfolio balance and purchasing power parity. The results show that real equity values were undervalued by 19 per cent by June 2005, with the gap narrowing thereafter. Foreign crises are important factors explaining this deterioration. The real wealth effects of equity market shocks impact significantly upon financial and goods market prices, whereas output tends to be immune. The model is also able to address puzzles that exist in the vector autoregression literature.

    Overcoming measurement error problems in the use of survey data on expectations
    Lee, K ; Shields, K (BLACKWELL PUBLISHING, 2007-09)
    Survey data frequently requires conversion from qualitative responses to quantitative series and it is often asserted that the conversion procedures introduce measurement errors that render the series unusable in structural modelling. We investigate the nature and treatment of the measurement error that arises when conversion procedures are used to obtain direct measures of expectations. We use simulation experiments to demonstrate the need for the adequate treatment of conversion errors and show that a procedure proposed to ‘purge’ the series of conversion error is extremely successful in circumventing the problems. We illustrate the procedures in empirical applications using business survey data.
