Tax Salience vs. Price Uncertainty: Disentangling the Effects of Attention and Rational Habits

Scott, Rebecca K - Department of Economics, Oxford University - 2014

A recent surge of literature on tax salience has included studies that use tax type as a proxy for salience. The … relationship between tax type and salience is not always apparent, however, nor is salience the only feature by which taxes differ … salient. This paper develops a model to disentangle and test for tax salience and rational habits effects. Differentiating …

A Reconsideration of the Optimal Income Tax

Roberts, Kevin - Department of Economics, Oxford University - 2000

This paper develops a formula for the optimal nonlinear income tax, the terms of which are familiar from the theory of linear income taxation. The development uses the idea of a perturbation of the optimal schedule and is based upon as assumption of differentiability. It is also shown that the...

Teacher Shocks and Student Learning: Evidence from Zambia

Dercon, Stefan - Department of Economics, Oxford University - 2004

We examine the effect of shocks to teacher inputs on child performance in school. We start with a household optimization framework where parents spend optimally in response to teacher and other school inputs. This helps to isolate the impact of teachers from other inputs. As a proxy measure for...

When Can School Inputs Improve Test Scores?

Dercon, Stefan - Department of Economics, Oxford University - 2004

Most studies fail to find an impact of school inputs on outcomes such as test scores. We argue that this might be a consequence of ignoring the possibility that households respond optimally to changes in school inputs and thus obscure the real effect of such provision on cognitive achievement....

Migration, Remittances and Public Transfers: Evidence from South Africa

Sienaert, Alex - Department of Economics, Oxford University - 2007

What drives migration and remittance behaviour in South Africa, and what are the implications for public policy? This paper evaluates existing empirical evidence, posits a simple theoretical model and undertakes a fresh evaluation using longitudinal data spanning 1993 to 2004 from KwaZula-Natal...

Rational Habits and Uncertain Prices: Simulating Gasoline Consumption Behavior

Scott, K. Rebecca - Department of Economics, Oxford University - 2012

When consumers are forward-looking with respect to their demand for a habit-forming good, traditional measures of price elasticity are misleading. In particular, such measures will underestimate sensitivity to long-run shifts - and therefore underestimate the potential effect of policy...

Time Inconsistent Environmental Policy and Optimal Delegation

Helm, Dieter; Hepburn, Cameron; Mash, Richard - Department of Economics, Oxford University - 2003

Time consistency problems can arise when environmental taxes are employed to encourage firms to take irreversible abatement decisions. Setting a high carbon tax, for instance, would induce firms to invest in low-carbon technology, yet once investment has occurred the government can then reduce...

Decomposition of Household Expenditure and Child Welfare in Rural Ethiopia

Kebede, Bereket - Department of Economics, Oxford University - 2003

The methodology by Lazear and Michael (1988) is used to decompose household expenditures into that for adults and children. Some specific estimation procedures are modified and cross section-time series (panel) data are used to control for household level heterogeneity. In addition, a new and...

Smoking and Endogenous Mortality: Does Heterogeneity in Life Expectancy Explain Differences in Smoking Behavior?

Lechene, Valerie; JérÃƒÂ³me Adda - Department of Economics, Oxford University - 2001

This paper proposes a joint model of tobacco consumption and mortality over the life-cycle. The decision to smoke is a trade off between current utility derived from smoking and a mortality risk increasing with age. Individuals with a longer potential life expectancy have more incentive to cut...

Revealed preferences over risk and uncertainty

Quah, John; Polisson, Matthew; Renou, Ludovic - Department of Economics, Oxford University - 2015

Consider a finite data set where each observation consists of a bunde of contingent consumption chosen by an agent from a constraint set of such bundles. We develop a general procedure for testing the consistency of this data set with a broad class of models of choice under risk and under...
