This research, supported by the Leverhulme Trust, investigates the relationship between the employment status of husbands and the labour market behaviour of their wives. In the UK the unemployment insurance system encourages the wives of unemployed men who are in receipt of unemployment benefit...

It is well known that over the next few decades there will be significant changes in the demographic structures of nearly all developed countries; in the absence of massive immigration, or of catastrophic new fatal illnesses, by the middle of the next century the ratio of people of working age...

For small group sizes, the Generalised Least Squares (CLS) estimator in multilevel models is biased and inconsistent when the random cluster effects are correlated with the regressors. A fixed effects approach, conditioning on the cluster effects, provides consistent estimates for the slope...

This paper investigates whether tax competition can survive under tax coordination, when information is private or nonverifiable. We focus on a two-jurisdiction model where capital can move across jurisdictions, and where the two jurisdictions have different public good requirements, but are...

This paper investigates whether the impact of financing constraints on company investment spending differs between firms in Belgium, France, Germany and the UK. Many previous studies have found that investment spending displays "excess sensitivity to cash flow" for individual countries, and...

According to the econometric literature, unemployed jobseekers who use a Public Employment Agency (PEA) have longer unemployment spells than those choosing alternative search methods. This contrasts sharply with the findings from well-designed US experiments where treatments subject to increased...

The generalized method of moments (GMM) estimation technique is discussed for count data models with endogenous regressors. Count data models can be specified with additive or multiplicative errors and it is shown that, in general, a set of instruments is not orthogonal to both error types....

We show that older male pensioners have substantially lower incomes than younger pensioners. There are a number of possible reasons for this including under-indexation of private pensions and the running down of income-producing assets. In fact we find that cohort differences more than account...

Many budget surveys present the interesting feature that for a wide range of goods they contain information, not only on expenditures, but also on quantities consumed. This allows the computation of individual unit values for the spending of each household on any good for which this is true. The...

Both direct utility function and Frisch cost function representations of demand system rank are derived. The results are used to construct a revealed preference (GARP) type test of rank. They are also used to derive results involving block separability, additive separability, and the class of...
