This paper develops methods of investigating the existence and extent of cointegration in fractionally integrated systems. We focus on stationary series, with some discussion of extension to nonstationarity. The setting is semiparametric, so that modelling is effectively confined to a...

We frequently observe that one of the aims of time series analysts is to predict future values of the data. For weakly dependent data, when the model is known up to a finite set of parameters, its statistical properties are well documented and exhaustively examined. However, if the model was...

We develop generalised indirect inference procedures that handle equality and inequality constraints on the auxiliary model parameters. We also show that the asymptotic efficiency of such estimators can never decrease by explicitly taking into account Lagrange multipliers associated with...

This paper examines the determinants of self-employment success for microcredit borrowers. Theories of social capital and neighbourhood effects are integrated in an attempt to account for earnings differentials amongst a unique sample of microfinance borrowers. The paper posits that social...

This paper brings together data from the 1998 Workplace Employee Relations Survey, National Survey of Unions and TUC focus on recognition survey to investigate influences on union organising effectiveness. Organising effectiveness is defined as the ability of trade unions to recruit and retain...

Parametric estimation is discussed in a variety of models exhibiting longrange dependence

This Paper shows how microeconomic data on investment plans can be used to study the structure of risk faced by firms. Revisions of investment plans form a martingale, and thus reveal the underlying shocks driving investment. We decompose revisions in investment plans into micro, sector and...

Given recent emphasis on externality to education, macroeconomic studies have a role to play in the analysis of return to schooling. In this paper we study the connection between growth and human capital in a convergence regression for the panel of Italian regions. We include measures of...

Over the period since 1970, Britain has improved its relative productivity performance, but there remains a significant gap in market sector productivity between Britain and both Continental Europe and the United States. Much of the gap between Britain and Continental Europe is due to lower...

When firms cluster in the same local labor market, they face a trade-off between the benefits of labor pooling (i.e., access to workers whose knowledge help reduce costs) and the costs of labor poaching (i.e., loss of some key workers to competition and the indirect effect of a higher wage bill...
