This paper investigates the relationship between product market competition (PMC) and innovation. A Schumpeterian growth model is developed in which firms innovate ѳtep-by-stepҬ and where both technological leaders and their followers engage in R&D activities. In this model, competition...

This paper uses the first twelve waves of the British Household Panel Survey covering the period 1991-2002 to investigate single women's labour supply changes in response to three tax and benefit policy reforms that occurred in the 1990s. We find evidence of small labour supply effects for two...

<p>We summarise what economic theory predicts about how retirement savings decisions are affected by marginal withdrawal rates created by the tax, tax credit and benefit system, and by the information individuals are provided with. All these predictions vary across individuals with their...</p>

This paper analyzes the relationship between aggregate wages and individual wages when there is time series variation in employment and in the dispersion of wages. A new and easily implementable framework for the empirical analysis of aggregation biases is developed. Aggregate real wages are...

We extend the collective model of household behavior to allow for the existence of public consumption. Under a separability assumption, we show that the observation of the labor supplies and the household demand for the public good allow to identify preferences and the decision process up to...

<p>Significant departures from log normality are observed in income data, in violation of Gibrat's law. We identify a new empirical regularity, which is that the distribution of consumption expenditures across households is, within cohorts, closer to log normal than the distribution of income. We...</p>

This paper is an evaluation of the British labor market program the "New Deal for the Young Unemployed" using administrative panel data on individuals between 1982 and 1999. This mandatory program involves extensive job assistance followed by various other options, including wage subsidies. We...

This paper develops a new separability concept - latent separability. This is shown to provide a useful empirical and theoretical framework for investigating the grouping of goods and prices. It is a generalisation of weak separability in which groups are identified by specific exclusive goods...

<p>This paper examines the tax schedule for low income families with children. We take an optimal tax approach based on a structural labour supply model which incorporates unobserved heterogeneity, fixed costs of work, childcare costs and the detailed non-convexities of the tax and transfer system....</p>
