    A number of misleading or incorrect comments by C.Giunti on seven arXiv preprints that I have written on the theory of neutrino oscillations are discussed. The essential new features of my approach are also briefly reviewedComment: 5 pages, no figures, no table

    A comment on the paper `Coherence in Neutrino Oscillations' by C.Giunti. Either lepton flavour eigenstates or neutrino oscillations do not exist

    The definition of `lepton flavour eigenstates' introduced in a recent paper hep-ph/0302045 is in disagreement with the Standard Model prediction for the structure of the leptonic charged current and implies the absence of neutrino oscillations following pion decay, in contradiction to experimental dataComment: 5 pages, no tables, no figures.

    Economic Growth and Recovery in the United States, 1919-1941

    The first part of this chapter provides an overview of what lay behind record productivity growth in the US economy between 1929 and 1941. The second part considers the role of rigidities and other negative supply conditions in worsening the downturn and slowing recovery. While arguing consistently that the overarching explanation of the Great Depression will and should continue to emphasise a collapse and slow revival in the growth of aggregate demand, the chapter spends relatively little time on what drives this. The emphasis of the chapter is on aggregate supply—both the broad array of positive shocks that propelled potential and, eventually, actual output forward, and the negative conditions which, in interaction with aggregate demand, may have increased the size of the output gap and prolonged its persistence. An appendix offers discussion and updated calculations of productivity growth rates for the critical period 1929–41
