This paper develops a revealed preference methodology for exploring whether time inconsistencies in household choice are the product of nonstationarities at the individual level or the result of individual heterogeneity and renegotiation within the collective unit.  An empirical application to...

The conventional view is that an increase in the value of a natural resource can lead to private property over it.  Many Igbo groups in Nigeria, however, curtailed private rights over palm trees in response to the palm produce trade of the nineteenth and early twentieth centuries.  I present a...

In contrast to other studies, this paper examines the determinants of short-term child health by controlling for the long-term health status of children.  Using data from rural Ethiopia and linear mixed models that control for individual heterogeneity, the empirical analysis indicate that the...

The paper contrasts early theories of the utility function (starting with Bentham and elaborated by Jevons) with the modern theory (laid down by Fisher and Samuelson).  The former include in the utility function not only the sensation of current events but also the memory of past events and the...

We undertake a generalization of the cumulative sum of squares (CUSQ) test to the case of non-stationary autoregressive distributed lag models with quite general deterministic time trends.  The test may be validly implemented with either ordinary least squares residuals or standardized...

This paper introduces a class of cointegration tests based on estimated low-pass and high-pass regression coefficients from the same wavelet transform of the original time series data.  The procedure can be applied to test the null of cointegration in a n + k multivariate system with n...

We consider model selection for non-linear dynamic equations with more candidate variables than observations, based on a general class of non-linear-in-the-variables functions, addressing possible location shifts by impulse-indicator saturation.  After an automatic search delivers a simplified...

India's development experience over the past fifty years suggests that the increasing importance of the services sector deserves analysis.  The literature on structural change has emphasised changing patterns of demand as an explanation for the increasing importance of the services sector.  In...

We propose a new, easy-to-implement, class of payment rules, "Reference Rules", to make core-selecting package auctions more robust.  Small, almost-riskless, profitable deviations from "truthful bidding" are often easy for bidders to find under currently-used payment rules.  Reference Rules...

I discuss models which allow the local level model, which rationalised exponentially weighted moving averages, to have a time-varying signal/noise ratio.  I call this a martingale component model.  This makes the rate of discounting of data local.  I show how to handle such models...
