In this paper we develop a theory of union bargaining power based on firm-specific skills acquired by the insider work-force. We show that unions increase the bargaining power of insiders only in states of the world in which the firm would like to retain insiders but not hire outsiders. Union...

After unification, real wages in Eastern Germany rose rapidly relative to labour productivity despite high and rising levels of unemployment. This substantial increase in wage levels relative to those in Western Germany is difficult to explain without recourse to models of union behaviour or...

Several recent studies based on 'exogenous' sources of variation in education outcomes show Instrumental Variables (IV) estimates of returns to schooling that are substantially higher than the corresponding Ordinary Least Squares (OLS) estimates. Card (1995a) suggests that these results can be...

An important component of the long-run cost of a war is the loss of human capital, suffered by children of schooling age who receive less education because of the war. This paper shows that in the European countries involved in World War II, children who were ten years old during the conflict...

Wages may be observed to increase with seniority because of firm-specific human capital accumulation or because of self-selection of better workers in longer jobs. In both these cases the upward sloping wage profile in cross-sectional regressions would reflect higher productivity of more senior...

This paper analyses the Rubinstein bargaining game with random alternating offers when the firm has an inventory of finished goods. If the firm can sell out of that inventory during a strike, we show that the negotiated wage is a decreasing function of the inventory stock. Conversely, if the...

This paper attempts to explain disparities among the unemployment experiences of different OECD countries in terms of the `fragility' of the short-run unemployment equilibrium (the impact of labour market shocks on the short-run unemployment rate) and the lag structure of the employment...

This paper shows that search in the labour market has important effects on accumulation decisions. In a labour market characterized by search, employment contracts are naturally incomplete and this creates a wedge between the rates of return and marginal products of both human and physical...
