We exploit a unique data-set matching individual-level data for the 1993 cohort of UK university leavers to DfEE school-level data. We analyze the determinants of undergraduate degree performance using an ordered probit regression model, and find that degree performance is influenced positively...

This paper describes simple methods for testing various hypotheses of proportionality between the cause-specific hazards in competing risks models. It provides methods for estimating competing risks models with equality restrictions across the cause-specific hazards as single risk models. Thus,...

type="main" xml:id="obes12063-abs-0001" <title type="main">Abstract</title> <p>The empirical literature on the determinants of charities’ donation income, distinguishing the charitable cause, is small. We consider the case of development charities specifically. Using a panel covering a quarter of a century, we observe a...</p>

This paper presents a convenient shortcut method for implementing the Heckman estimator of the dynamic random effects probit model and other dynamic nonlinear panel data models using standard software. It then compares the estimators proposed by Heckman, Orme and Wooldridge, based on three...

This note points out to applied researchers what adjustments are needed to the coefficient estimates in a random effects probit model in order to make valid comparisons in terms of coefficient estimates and marginal effects across different specifications. These adjustments are necessary because...

This article presents a formal explanation of the forecast combination puzzle, that simple combinations of point forecasts are repeatedly found to outperform sophisticated weighted combinations in empirical applications. The explanation lies in the effect of finite-sample error in estimating the...

This paper uses the multivariate cointegration technique of Johansen to construct a manufacturing imports equation for the UK over the period from 1970 to the end of 1991. Imports are modeled in share form with a unit long-run elasticity on demand. The long-run equations are similar to those...
