This paper sets up a general equilibrium model, in which firms are heterogeneous due to productivity differences and workers have fairness preferences and hence provide full effort only if their factor return is sufficiently high. With the wage considered to be fair by workers depending on the...

Theories in political economy depend critically on assumptions about motivations of politicians. Our analysis starts from the premise that politicians, like other economic agents, are rational individuals who make career decisions by comparing the expected returns of alternative choices. The...

We present a non-technical account of ambiguity in strategic games and show how it may be applied to economics and social sciences. Optimistic and pessimistic responses to ambiguity are formally modelled. We show that pessimism has the effect of increasing (decreasing) equilibrium prices under...

This paper examines the effects of the Working Families' Tax Credit (WFTC) on couples in Britain. We develop a simple model of household decisions which explicitly accounts for the role played by the tax and benefit system. Its main implications are then tested using panel data from the British...

This paper formulates a model to examine the effects of changes in tax-benefit policy on the behavior of divorced parents and the well-being of children in single-parent households. Noncustodial parents choose the level of a child support payment to transfer to custodians. These, in turn, decide...

The recent financial crisis has highlighted the limits of the 'originate to distribute' model of banking, but its nexus with the macroeconomy and monetary policy remains unexplored. I build a DSGE model with banks (along the lines of Holmström and Tirole [28] and Parlour and Plantin [39]) and...

Several authors have proposed staggered wage bargaining as a way to introduce sticky wages into search and matching models while preserving individual rationality. I evaluate the quantitative implications of such an approach. I feed through a series of estimated shocks from US data into a search...

This paper documents a puzzling fact, namely that there is a significant negative relation between employment protection legislation and the usage of the intensive margin of labor market adjustments. We then make use of a Real Business Cycle model and introduce search and matching frictions as...

Empirical data indicate that firms tend to have below-average productivity upon entry and that they tend to experience post-entry productivity growth. I present a New Keynesian model with growth in firm-specific productivity and firm turnover that captures these two phenomena. The model predicts...
