This note provides a simple exposition of what IV can and cannot estimate in a model with a binary treatment variable and heterogeneous treatment effects. It shows how linear IV is a misspecification of functional form and the reason why linear IV estimates for this model will always depend on...

This paper documents the convergence of incomes across Indian states over the period 1965 to 1998. It departs from traditional analyses of convergence by tracking the evolution of the entire income distribution, instead of standard regression and time series analyses. The findings reveal...

Equilibrium models have been proposed in literature with the aim of describing the evolution of the price of emission permits. This paper derives first a reducedform model from an equilibrium model and thereby explains how existing reducedform models are related to equilibrium models. Second, by...

The non-negativity constraint on inventories imposed on the rational expectations theory of speculative storage implies that the conditional mean and variance of commodity prices are non-linear in lagged prices and have a kink at a threshold point. In this paper, the structural parameters of...

This article examines the links that have recently been studied between poverty, high fertility and undernourishment, on the one hand, and degradation of the local environmental-resource base and civic disconnection, on the other, in poor countries. An account is offered of a number of pathways...

Sometimes regulators become experimenters: they try ideas out before implementing them, put novel schemes to the test in order to predict their likely impact, or conduct pilot programmes before executing new policies. Regulators find experiments very expedient, as they allow them to forecast the...

Abstract Commentators on the `East Asian Miracle' of inclusive growth have often pointed toward shared rural growth policies. But why were these policies not chosen elsewhere? This paper models voters who invest in either subsistence or a complex technology in which public goods complement...

It has been suggested in the literature that taxes and subsidies play an important role in explaining the differences in working hours across countries. In this paper I test whether public programmes for family support play a role in explaining this variation. I analyse two types of policies:...

In this paper we examine the concept of "vulnerability" (Townsend 1994) within the context of income mobility of the poor. We test for the dynamics of vulnerable households in the UK using Waves 1 - 12 of the British Household Panel Survey and find that, of three different types of risks that we...

We focus on the statics and dynamics of poverty in Spain using data from the first eight waves of the European Community Household Panel from 1994 to 2001, a period not sufficiently covered by recent literature. The results confirm the pattern of poverty changes noted by other authors for the...
