There are substantial cross-country differences in labor supply late in the life cycle (age 50+). A theory of labor supply and retirement decisions is developed to quantitatively assess the role of social security, disability insurance, and taxation for understanding differences in labor supply...

We build a heterogeneous life-cycle model which captures a large number of salient features of individual labor supply, by education, over the life cycle. The model provides an aggregation theory of individual labor supply, firmly grounded on micro evidence, and is used to study the aggregate...

We build a heterogeneous life-cycle model which captures a large number of salient features of individual labor supply over the life cycle, by education, both along the intensive and extensive margins. The model provides an aggregation theory of individual labor supply, firmly grounded on...

This paper explores two models of an economy in which contracts are exchanged. In the first version contracts are exchanged on a competitive market in which traders expectations concerning conditions that prevail within specific markets adjust until markets `clear'. In the second model contract...

Bedevilling the ongoing debate about changes in real-incomes in late-medieval western Europe, especially during the so-called 'Golden Age of the Labourer', is the very troubling issue of 'wage-stickiness'. The standard and long-traditional explanation for this supposed 'Golden Age' of rising...

One of the most common myths in European economic history, and indeed in Economics itself, is that the Black Death of 1347-48, followed by other waves of bubonic plague, led to an abrupt rise in real wages, for both agricultural labourers and urban artisans – one that led to the so-called...

The traditional and almost universal method of expressing real wages is by index numbers, according to the formula: RWI = NWI/CPI: i.e., the real wage is the quotient of the nominal (money) wage index divided by the consumer price index, all employing a common base period (here: 1451-75 = 100)....

This comparative study of money, coinages, prices, and wages in southern England and the southern Low Countries had its origins in a series of appendices and footnotes for the first twelve volumes of the Correspondence of Erasmus (1484-1527), part of the Collected Works of Erasmus, which the...

This paper re-examines the classic demographic or 'real' model, essentially based on a Malthusian-Ricardian model, that the late Michael Postan (Cambridge) utilized to explain the behaviour of the later-medieval western European economy, and in particular the behaviour of price movements. In...

We examine the behaviour of the nonparametric maximum likelihood estimator (NPMLE) for a discrete duration model with unobserved heterogeneity and unknown duration dependence. We find that a nonparametric specification of either the duration dependence or unobserved heterogeneity, when the other...
