In this paper, bivariate probit estimation procedures and nonindependent selectivity adjustments are employed to investigate the determinants of the joint welfare participation-labor supply decisions made by single males, single females, lone fathers, and lone mothers, using data from the...

The longitudinal, 1988-89 LMAS makes it possible to study the interaction between social assistance and labour supply while allowing for substantial time dependence. Tobit equations for hours worked on and off social assistance, which allow for endogenous selection of social assistance status,...

We conduct an update of the ranking of economic journals by <link>Kalaitzidakis, Mamuneas, and Stengos (2003)</link>. However, our present study differs methodologically from that earlier study in an important dimension. We use a rolling window of years between 2003 and 2008, for each year counting the...

We extend the sensitivity analysis of cross-country growth regressions of Levine and Renelt (1992) by introducing a semi-parametric formulation of their regression function. Our results differ from theirs in how certain policy variables affect growth rates. We find that distortion variables,...

This paper examines the joint pricing decision of products in a firm's product line. When products are distinguished by a vertical characteristic, those with higher values of that characteristic will command higher prices. We investigate whether, holding the value of the characteristic constant,...

An additive partially linear regression model is used to estimate non-parametrically the effects of total expenditure and age in the context of Engel curves and to investigate the specification and welfare interpretation of the age effects in parametric models of consumer behaviour. Empirical...
