This paper investigates, in a unified framework, the effects of sibship size, birth order and sibling sex composition on children's school enrolment in urban Turkey. We utilize an instrumental variable estimation method to address parents' joint fertility and schooling decisions using twin...

The phenomenon that married men earn higher average wages than unmarried men - the marriage premium - is well known. However, the robustness of the premium across the wage distribution and the underlying causes of the marriage premium are unclear. Focusing on the entire wage distribution and...

The main goal of this paper is to warn practitioners of the danger of neglecting outliers in regression analysis, in particular, good leverage points (i.e. points lying close to the regression hyperplane but outlying in the "x"-dimension). While the types of outliers which do influence...

I derive the exact distribution of the exact determined instrumental variable estimator using a geometric approach. The approach provides a decomposition of the exact estimator. The results show that by geometric reasoning one may efficiently derive the distribution of the estimation error. The...

We show that improvements in aggregate productivity in UK manufacturing during the first years after the implementation of the Euro, by the UK's main trading partners in Europe, are determined by both market share reallocation and within-company productivity growth. Furthermore, we outline a...

Single-state generalized autoregressive conditional heteroscedasticity (GARCH) models identify only one mechanism governing the response of volatility to market shocks, and the conditional higher moments are constant, unless modelled explicitly. So they neither capture state-dependent behaviour...

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...

Recent studies find that exporters are more productive than non-exporters and that entry into exporting does not increase firms' productivity. Thus, firms self-select into foreign markets. This paper examines productivity before entry into exporting. Using Chilean plant-level data, we find that...

This paper describes a capital services dataset for the United Kingdom developed for use in empirical work, and some of its key features. The estimates are consistent with National Accounts output estimates, making them ideal for use in growth-accounting or business-cycle analysis. The...
