Using rich panel data recently available from Spanish Social Security records, we find that a negative motherhood earnings differential of 2.3 log points remains even after controlling for both individual- and firm-level unobserved heterogeneity. The analysis of the mothers and childless women's...

This paper is the first to examine the implications of switching to PT work for women's subsequent earnings trajectories, distinguishing by their type of contract: permanent or fixed- term. Using a rich longitudinal Spanish data set from Social Security records of over 76,000 prime-aged women...

While much of the literature that investigates the part-time (PT) / full-time (FT) hourly wage differential and its causes focuses on average effects, very few studies analyze the heterogeneous effects of PT work across different subgroups, despite the policy relevance of understanding channels...

Fixed effects estimators in nonlinear panel models with fixed and short time series length T usually suffer from inconsistency because of the incidental parameters problem first noted by Neyman and Scott (1948). Moreover, even if T grows but at a rate not faster than the cross sectional sample...

Part-time work has recently received renewed attention in Spain as its Prime Minister, José Luís Rodríguez Zapatero, has offered to use part-time (PT) work as a measure to increase labor market flexibility in the midst of the current economic crisis. However, little is known in Spain on...

The 2005 International Comparison Program's (ICP) estimates of economy-wide purchasing power parity (PPP) are based on parity estimates for 155 basic expenditure headings, mainly estimated using country product dummy (CPD) regressions. The estimates are potentially inefficient and open to...
