The behaviour of averaged periodograms and cross-periodograms of a broad class of nonstationary processes is studied. The processes include nonstationary ones that are fractional of any order, as well as asymptotically stationary fractional ones. The cross-periodogram can involve two...

Often for a non-regular parametric hypothesis, a tractable test statistic involves a nuisance parameter. A common practice is to replace the unknown nuisance parameter by its estimator. The validality of such a replacement can only be justified for an infinite sample in the sense that under...

This paper develops a simple model to show how social insurance affects the desire to revolt against property rights. It then tests for the effect of social insurance on revolt by introducing a panel data set derived from surveys across 200,000 randomly sampled individuals from the 1970s to the...

In this paper we propose to measure inequality of educational achievements by constructing a Gini index on educational attainments. We then use the proposed measure to analyse the relationship between inequality in incomes and educational achievements (in terms of both the average attainments...

We provide empirical evidence on the nature of spatial externalities in a matching model for the UK. We use a monthly panel of outflows, unemployment and vacancy stocks data from the registers at Jobcentres in the UK; these are mapped on to travel-to-work areas. We find evidence of significant...

Although property rights are the cornerstone of capitalist economics, throughout history existing claims have been frequently overturned and redefined by revolution. A fundamental question for economists is what makes revolutions more likely to occur. A large literature has found contradictory...

This article reports upon aspects of a small-scale qualitative study of low-income working families. The study was conducted in the context of recent policy changes in Britain that are intended to promote labour force participation by low-income parents, especially mothers. It is argued that...

Various versions of the wild bootstrap are studied as applied to regression models with heteroskedastic errors. It is shown that some versions can be qualified as 'tamed', in the sense that the statistic bootstrapped is asymptotically independent of the distribution of the wild bootstrap DGP....

In the mid-1980s, many European countries introduced fixed-term contracts. Since then their labor markets have become more dynamic. This paper studies the implications of such reforms for the duration distribution of unemployment, with particular emphasis on the changes in the duration...
