We apply duality methods of linear and convex programming to the problems of operation and rental valuation of facilities for conversion and storage of cyclically priced goods, e.g. , energy. Both problems are approached by shadow-pricing the stock (which is a purely intermediate commodity); and...

Emerging-market countries are being urged to choose between freely floating exchange rates and firmly fixed rates supported by strong institutional arrangementsûcurrency boards, monetary unions, or formal dollarization. This paper assesses the benefits and costs of institutionalizing fixed...

Frequency domain statistics are studied in the presence of fractional deterministic and stochastic trends. It is shown how the behaviour of the sample variance-covariance matrix of nonstationary processes can be dominated by components corresponding to a possibly degenerating band around zero...

This paper investigates why children work by studying the wage elasticity of child labour supply. Incorporating subsistence constraints in to a model of labour supply, we show that a negative wage elasticity favours the hypothesis that poverty compels work whereas a positive wage elasticity...

We derive the asymptotic distribution of a new backfitting procedure for estimating the closest additive approximation to a nonparametric regression function. The procedure employs a recent projection interpretation of popular kernel estimators provided by Mammen, Marron, Turlach and Wand...

The paper discusses the reasons for the observed variation in the sequencing, speed and content of reform policies, in the 1990s, among 25 post-socialist countries of Central Europe and the Former Soviet Union. It argues that these differences, while considerable in the early 1990s, did not...

This paper investigates the extent to which certain social characteristics and personal attributes could help explain income inequality in Greece. This analysis is quite revealing for understanding and explaining income idfferences among certain population subgroups with apparent policy...

This paper explores the extent to which the presence of ex-ante transaction costs may lead to failures of the Coase Theorem. In particular we identify and investigate the basic ‘hold-up problem’ which arises whenever the parties to a Coasian negotiation have to pay some ex-ante costs for the...

This paper challenges the consensus on the nature of unemployment dynamics in Britain. We show that the argument that changes in unemployment arise mostly from changes in the duration of unemployment (rather than in the chance of becoming unemployed) is flawed. In fact, while shocks to the...

The nonparametric censored regression model, with a fixed, known censoring point (normalized to zero), is y = max[0,m(x) + e], where both the regression function m(x) and the distribution of the error e are unknown. This paper provides estimators of m(x) and its derivatives. The convergence rate...
