A sequential procedure for determination of trend degree and testing for unit root is introduced; its properties are investigated by Monte Carlo experiments. We compare the performance of Augmented Dickey-Fuller tests and the GLS tests of Elliott, Rothenberg and Srock (1996), in both cases with lag...

We obtain an inequality for th esmaple varaince of a Brownian motion on [0,1] and an associated Ornstein-Uhlenbeck process. The result is applied to a regression involving a near-integrated regressor, and establishes that in the limit the dispersion of the least squares estimator is greater in...

In this paper, we analyse the behaviour of regression-based tests for seasonal unit roots when the error is periodically heteroscedastic. We show, using the case of quaterly data to illustrate, that the limiting null distribution of tests for unit roots at the zero and Nyquist frequencies are...

We introduce 'formal methods' of mechanized reasoning from computer science to address two problems in auction design and practice: is a given auction design soundly specified, possessing its intended properties; and, is the design faithfully implemented when actually run? Failure on either...

NREGS (Mahatma Gandhi National Rural Employment Guarantee Scheme) is the Indian government's flagship anti-poverty program and is one of the largest public works programmes in the world which aims to increase employment opportunities for the poor and in particular, improve women's access to the...

This paper uses the staggered implementation of a legal change in inheritance law in India to estimate the effect of women's improved access to inheritance on both police-reported and self-reported violence against women. I find a decrease in reported violence and female unnatural deaths...
