This paper sets out a general algorithm for calculating true cost-of-living indices or true producer price indices when demand is not homothetic, i.e. when not all expenditure elasticities are equal to one. In principle, economic theory tells us how we should calculate a true cost-of-living...

We look for evidence of habituation in twenty waves of German panel data: do individuals, after life and labour market events, tend to return to some baseline level of well-being? Although the strongest life satisfaction effect is often at the time of the event, we find significant lag and lead...

We look for evidence of adaptation in wellbeing to major life events using eighteen waves of British panel data. Adaptation to marriage, divorce, birth of child and widowhood appears to be rapid and complete; this is not so for unemployment. These findings are remarkably similar to those in...

Gaps in welfare attainment between boys and girls in China have attracted international attention. In this paper demand analysis is used to try and uncover the factors which may be driving the emergence of the gender gaps. Drawing on household expenditure data from a poor (Sichuan) and rich...

I set out a new method for estimating true (Konüs) PPPs. Household consumption per head deflated by these PPPs answers the question: by how much must the average expenditure per head of poor country A be increased to enable the typical inhabitant of A to enjoy the same utility level as the...

At the heart of any distributional analysis there is the problem of allowing for differences in people's non-income characteristics. We examine the role of standard equivalence scales in distributional comparisons and the welfare implications of the basis for constructing equivalence scales. We...

This paper analyses optimal irreversible investment policy when profits are subject to a multiplicative geometric Brownian motion shock. The marginal product of capital is increasing initially and decreasing thereafter. In the latter range, optimal policy is familiar: capacity is added gradually...

Growth of 'global cities' in the 1980s was supposed to have involved an occupational polarisation, including growth of low paid service jobs. Though held to be untrue for European cities, at the time, some such growth did emerge in London a decade later than first reported for New York. The...

The goal of the present paper is to investigate not only the dynamics of the Greek public debt, but also what are the appropriate measures required for achieving fiscal consolidation. The empirical estimation is carried out using a macroeconomic dataset spanning the period 1980-2008 and both the...

This paper introduces a new model for portfolio credit risk incorporating default and spread widening in a simple and consistent framework. Credit spreads are modelled by geometric Brownian motions with a dependence structure powered by a t-copula. Their joint evolution drives the spreads...
