TLDR
In this paper, the importance of the double-hurdle approach for modelling individuals' cigarette consumption, using data from the UK General Household Survey, and argues that participation and consumption should be treated as separate individual choices.Abstract:
This paper shows the importance of the double-hurdle approach for modelling individuals' cigarette consumption, using data from the UK General Household Survey, and argues that participation and consumption should be treated as separate individual choices. The likelihood function for the full double-hurdle is derived, and it is shown how restrictions on the stochastic specification of the model and auxillary information, which identifies ex-smokers, allow it to be decomposed. The empirical results highlight the value of the sample separation information and the need to model starting and quitting as separate decisions.read more

Health Behavior, Health Knowledge, and Schooling
TL;DR: Part of the relationship between schooling and the consumption of cigarettes, alcohol, and exercise is explained by differences in health knowledge, but most of schooling's effects on health behavior remain after differences in knowledge are controlled for.

Farmers' perceptions and adoption of new agricultural technology: evidence from analysis in Burkina Faso and Guinea, West Africa
TL;DR: In this article, a Tobit model of modern sorghum and rice varietal technologies in Burkina Faso and Guinea was used to test the hypothesis that farmers' perceptions of technology characteristics significantly affect their adoption decisions.

twopm: two-part models
TL;DR: The twopm command allows the user to leverage the capabilities of predict and margins to calculate predictions and marginal effects and their standard errors from the combined first- and second-part models.

IMF lending programs: Participation and impact
TL;DR: In this article, a detailed analysis of such participation over the period 1976-1986 provides a number of insights into the motivations for and the macroeconomic effects of participation in the IMF programs.

Sample selection versus two-part models revisited: the case of female smoking and drinking.
TL;DR: The debate between Heckman sample selection and two-part models in health econometrics is revisited in the context of female smoking and drinking, and the two approaches are evaluated on three grounds: theoretical, practical and statistical.

Sample Selection Bias as a Specification Error
TL;DR: In this article, the bias that results from using non-randomly selected samples to estimate behavioral relationships as an ordinary specification error or "omitted variables" bias is discussed, and the asymptotic distribution of the estimator is derived.

A Simple Test for Heteroscedasticity and Random Coefficient Variation.
Trevor Breusch,Adrian Pagan +1 more
TL;DR: In this paper, a simple test for heteroscedastic disturbances in a linear regression model is developed using the framework of the Lagrangian multiplier test, and the criterion is given as a readily computed function of the OLS residuals.

Some statistical models for limited dependent variables with application to the demand for durable goods
TL;DR: This article developed several models for limited dependent variables, which are extensions of the multiple probit analysis model and differ from that model by allowing the determination of the size of the variable when it is not zero to depend on different parameters or variables from those determining the probability of its being zero.

The World of Goods
Mary Douglas,Baron Isherwood +1 more
TL;DR: The World of Goods as mentioned in this paper is a classic of economic anthropology whose insights remain compelling and urgent, arguing that poverty is caused as much by the erosion of local communities and networks as it is by lack of possessions and contrast small-scale with large-scale consumption in the household.
