In this appendix we expand the explanation in Subsection 4.3.1. The IV estimate of the export elasticity to finance is 7.8 times larger than the OLS estimate. We expect the attenuation bias of the OLS estimator to be of the such order of magnitude. This is why. We are interested in the following model of supply-induced variation in exports —demand variation is absorbed by the product-destinatio...

Estimates of intergenerational economic mobility that use point in time measures of income and earnings suffer from lifecycle and attenuation bias. We consider these issues for the National Child Development Study (NCDS) and British Cohort Study (BCS) for the first time, highlighting how common methods used to deal with these biases do not eradicate these issues. To attempt to overcome this, we...

This the problem maximum asymptotic bias of regression estimates over a-contamination for the joint of the response carriers. Two classes of estimates are treated: (1) Msestimates with bounded function p applied to the scaled residuals, using a very general class of scale estimates, and (2) Bounded influence function type generalized M-estimates. Estimates in the first class are oblta1rled as p...

Simultaneous solar wind measurements from the monitors, WIND and ACE, differ due to spatial temporal structure of wind. Correlation studies that use these as input may infer an incorrect correlation uncertainties arising this structure, especially at extreme rare values. In particular, regression analysis will lead a function whose slope is biased towards mean value measurement parameter. This ...

We analyze the decision to announce an open market share repurchase and the share price reaction to the announcement. We use a conditional estimation approach which takes into account that the repurchase decision is made rationally and that, consequently, there is a potential selection bias. This approach requires a ‘non-event sample’ of firms that could reasonably be expected to announce a rep...
