This paper uses the 1998-99 Canadian National Population Health Survey (NPHS) data to examine the health-income relationship that underlies the absolute income hypothesis. To allow for nonlinearity and data heterogeneity, we use a partially linear semiparametric quantile regression model. The...

Stabilizing pollution levels in the long run is a pre-requisite for sustainable growth. We develop a neoclassical growth model with endogenous emission reduction predicting that, along optimal sustainable paths, pollution growth rates are (i) positively related to output growth (scale effect)...

This paper extends the simple threshold regression framework of Hansen (2000) and Caner and Hansen (2004) to allow for endogeneity of the threshold variable. We develop a concentrated least squares estimator of the threshold parameter based on an inverse Mills ratio bias correction. We show that...

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

We conduct an update of the ranking of economic journals by Kalaitzidakis, Mamuneas and Stengos (2003). 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 number...

We consider the effects of demographic and expenditure variables on consumer demand in a system of Engel curves using a smooth coefficient semiparametric model where the expenditure effects on the budget shares vary nonparametrically with demographic variables such as the age of head and number...

We investigate the evolution of global welfare in two dimensions: income per capita and life expectancy. First, we estimate the marginal distributions of income and life expectancy separately. More importantly, in contrast to previous univariate approaches, we consider income and life expectancy...

In this paper we examine the effect of pollution, as measured by CO2 emissions, on economic growth among a set of OECD countries during the period 1981-1998. We examine the relationship between total factor productivity (TFP) growth and pollution using a semiparametric smooth coefficient model...

This paper examines the effect of FDI on the process of economic growth by allowing the impact to differ both across each country and also across each time period. We apply non-parametric techniques taking into account the previously documented nonlinear effects of initial income and human...

This paper extends the simple threshold regression framework of Hansen (2000) and Caner and Hansen (2004) to allow for endogeneity of the threshold variable. We develop a concentrated two-stage least squares (C2SLS) estimator of the threshold parameter that is based on an inverse Mills ratio...
