Re-examining the sources of ethnic inequality in Vietnam, we use an instrumental variable approach to provide consistent estimators of explanatory variables at household and commune levels for ethnic differences in household expenditure per person. Four key conclusions are drawn. First, removing...

The method of 'excess sensitivity' of Bajada (1999, 2000, 2001) indicates a large underground economy in Australia, with estimates of unrecorded income approximately 15 per cent of official gross domestic product. These estimates concern policy-makers, especially those agencies responsible for...

This paper analyses the properties of the fixed-effects vector decomposition estimator, an emerging and popular technique for estimating time-invariant variables in panel data models with unit effects. This estimator was initially motivated on heuristic grounds, and advocated on the strength of...

Bajada (2006) recognises that his earlier books and papers used a faulty method for measuring the underground economy in Australia. He also reports finding a new “more serious problem” in the method. All of these failures can be avoided, it is claimed, by reduced use of currency modelling...

This paper re-examines the sources of inequality in Vietnam, a transitional economy with large reductions in poverty from recent and dramatic economic growth, but vastly unequal gains across ethnic groups. Using an instrumental variable approach to provide consistent estimators of explanatory...

Are global temperatures on a warming trend? It is difficult to be certain about trends when there is so much variation in the data and very high correlation from year to year. We investigate the question using statistical time series methods. Our analysis shows that the upward movement over the...
