The authors report new evidence on the existence of sex discrimination in wages and whether competitive market forces act to reduce or eliminate discrimination. Specifically, they use plant- and firm-level data to examine the relationships between profitability, growth and ownership changes, product market power, and the sex composition of a plant's or firm's workforce. Their strongest finding is that among plants with high levels of product market power, those that employ relatively more women are more profitable. No such relationship exists for plants with apparently low levels of market power. This is consistent with sex discrimination in wages in the short run in markets where plants have product market power. The authors also examine evidence on the longer-run effects of market forces on discrimination, asking whether discriminatory employers with market power are punished over time through lower growth than non-discriminatory employers, or whether discriminatory employers are bought out by non-discriminators. There was found little evidence that this occurs over a five-year period, as growth and ownership changes for plants with market power are generally not significantly related to the sex composition of a plant's workforce.

This article deals with two problems: the timing of exits from the teaching profession and the reasons for these exits. Approximately 67 % of exiting female teachers leave the work force altogether. The presence of a newborn child is the single most important determinant of exits for females. The paper discusses why studies of quit behavior that simply include a person's total number of children may fail to capture the true importance of fertility behavior on a female's quit decision. It is also examined in this paper the return rates of departing teachers and compares the exit behavior of teachers to that of nonteachers.

This paper examines the impact of childcare prices and wage rates on the joint employment and childcare mode (center, sitter, relative, and husband) choice decisions of married mothers by estimating both a mixed logit and universal logit choice model. Data are drawn from the 1988 Canadian National Child Care Survey and the 1988 Labour Market Activity Survey. The estimation results show that wages have a positive impact on the probability of choosing any of the working states and that childcare prices for center, sitter, and relative care reduce the probability of working and using each respective mode of care. Sensitivity analyses reveal that the wage elasticity for employment is fairly robust across model specifications, while the own-price elasticity of childcare is sensitive to model specification, differing identifying assumptions in the estimation of childcare price equations, and sample selection. The simulation results show that differences exist in the degree to which government subsidies in the form of wage subsidies, targeted childcare subsidies, or unconditional childcare subsidies, impact on labor supply decisions and decisions to substitute across different modes of care by those mothers already in the labor market.

Return to employment, after a period of unemployment, is analyzed for a large sample of Swedish occupationally disabled workers. A piece-wise constant model is used, extended to allow for Gamma heterogeneity. Three competing exits from unemployment are accounted for; regular employment, sheltered/subsidized employment and withdrawal from the labor force. The model is also generalized by accounting for differing search behavior within the population. The hazard rate is constant or slightly increasing over time, for exit to some kind of employment. However, for exit from unemployment by leaving the labor force, the hazard shows quite strong positive duration dependence. Men tend to be more probable to leave unemployment for regular employment, and less probable than women to leave the labor force. The probability of finding regular employment is smallest for workers with psychological disabilities, while high-school or university education as well as previous professional experience increases the hazard rate for regular employment. The heterogeneity due to differing search behavior appears to be at least as important as the Gamma heterogeneity. The estimated probabilities of no search for one particular exit varies, across exits and subsamples, between 0.0 and 0.4.

This paper studies the interaction between time inconsistency problems in labor market policy and monetary policy. When both policies are discretionary, there is a positive inflation bias, whereas the bias in labor market programs may be either positive or negative. A commitment of labor market programs to zero increases inflation, as compared to the case when both labor market policy and monetary policy are discretionary. Delegation of labor market policy to a liberal labor market board may improve the discretionary outcome, even if labor market programs crowd out regular employment. A conservative central bank always reduces the social loss, even when monetary policy interacts with labor market policy.

The Swedish experiences of the 1990s provide a unique example of how large-scale active labour market programmes (ALMPs) have been used as a means to fight high unemployment. This paper discusses the mechanisms through which ALMPs affect (un)employment and surveys the empirical studies of the effects of ALMPs in Sweden. The main conclusions are: (i) there is hardly any evidence for a positive effect on matching efficiency; (ii) there are some indications of positive effects on labour force participation; (iii) subsidised employment seems to cause displacement of regular employment, whereas this appears not to be the case for labour market training; (iv) it is unclear whether or not ALMPs raise aggregate wage pressure in the economy; (v) in the 1990s, training programmes seem not to have enhanced the employment probabilities of participants, whereas some forms of subsidised employment seem to have had such effects; and (vi) youth programmes seem to have caused substantial displacement effects at the same time as the gains for participants appear uncertain. On the whole, ALMPs have probably reduced open unemployment, but also reduced regular employment. The overall policy conclusion is that ALMPs of the scale used in Sweden in the 1990s are not an efficient means of employment policy. To be effective, ALMPs should be used on a smaller scale. There should be a greater emphasis on holding down long-term unemployment in general and a smaller emphasis on youth programmes. ALMPs should not be used as a means to renew unemployment benefit eligibility.

This paper investigates the extent to which employees with a casual employment contract can be viewed as a group with broadly similar personal characteristics and work arrangements. If most casual contract employees are similar, then it is probably valid to make general conclusions about their circumstances. Conversely, the presence of considerable diversity would suggest that generalisations about casual contract employment are inappropriate. This issue is of interest because generalisations are often made about how the welfare of workers has been affected by the rapid increase in casual employees as measured in regular surveys by the Australian Bureau of Statistics (ABS).

Recent advances in incentive theory stress the multi- dimensional nature of agent effort and particularly the case where workers can improve the performance of others through `helping' efforts. This paper provides a simple model of an agent's incentive to help depending on the compensation package, the cost of monitoring, and the allocation of tasks. We then analyze the determinants of reported helping efforts within workgroups for a sample of Australian workers. As expected, workers are less likely to help one another when promotion incentives are strong. Subsidiary results are consistent with our `contest' interpretation of this finding and not consistent with `gift exchange' or other variants of the efficiency wage hypothesis. Also as predicted, a wide range of job tasks amplifies the negative effect of promotional incentives, while monitoring of help mitigates the negative effect. We find an unexpected positive effect of piece rates on helping effort for long-term employees which we show is consistent with repeated game effects between workers. These considerations do not overturn our findings about the effects of tournaments.

This paper describes the labor market in general, and the job search process in particular, as stochastic decay processes. this has implications in terms of information, discrimination and the Natural Rate Hypothesis.

This paper extends the theory of investment under uncertainty to incorporate fixed costs of investment, a wedge between the purchase price and sale price of capital, and potential irreversibility of investment. In this extended framework, investment is a non-decreasing function of q, the shadow price of installed capital. There are potentially three investment regimes, which depend on the value of q relative to two critical values. For values of q above the upper critical value, investment is positive and is an increasing function of q, as is standard in the theory branch of the adjustment cost literature. For intermediate values of q, between two critical values, investment is zero. Although this regime features prominently in the irreversibility literature, it is largely ignored in the adjustment cost literature. Finally, if q is below the lower critical value, gross investment is negative, a possibility that is ruled out by assumption in the irreversibility of literature. In general, however, the shadow price q is not directly observable, so we present two examples relating q to observable varieties.

A historical look at the origin and uses of the word inflation, arguing that although the term has become nearly synonymous with "price increase," its original meaning--a rise in the general price level caused by an imbalance between the quantity of money and trade needs--is the definition driving many of those who advocate an anti-inflation policy for the Federal Reserve.
