Models for the Analysis of Labor Force Dynamics

Abstract: This paper presents new econometric methods for the empirical analysis of individual labor market histories. The techniques developed here extend previous work on continuous time models in four ways: (1) A structural economic interpretation of these models is presented. (2) Time varying explanatory variables are introduced into the analysis in a general way. (3) Unobserved heterogeneity components are permitted to be correlated across spells. (4) A flexible model of duration dependence is presented that accommodates many previous models as a special case and that permits tests among competing specifications within a unified framework. We contrast our methods with more conventional discrete time and regression procedures. The parameters of continuous time models are in- variant to the sampling time unit used to record observations. Problems plague the regression approach to analyzing duration data which do not plague the likelihood approach advocated in this paper. The regression approach cannot be readily adopted to accommodate time varying explanatory variables. The functional forms of regression functions depend on the time paths of the explanatory variables. Ad hoc solutions to this problem can make exogenous variables endogenous to the model and so can induce simultaneous equations bias. Two sets of empirical results are presented. A major conclusion of the first analysis is that the discrete time Markov model widely used in labor market analysis is inconsistent with the data. The second set of empirical results is a test of the hypothesis that "unemployment" and "out of the labor force" are behaviorally different labor market states. Contrary to recent claims, we find that they are separate states for our sample of young men.

Temporary Contracts and Employee Effort

Abstract: Temporary contracts provide employers with a tool to screen potential new employees and have been shown to provide 'stepping stones' into permanent employment for workers. For both reasons, workers on temporary contracts have an incentive to provide more effort than permanent employees. Using indicators for unpaid overtime work and absences taken from the Swiss Labor Force Survey, we present evidence that temporary workers indeed provide higher effort than permanent employees: their probability of working unpaid overtime exceeds that of permanently employed workers by 60%. We show the heterogeneity of this effect across different types of temporary contracts, investigate differences between men and women, and discuss the relevance of endogenous selection into temporary employment.

Do Incentive Contracts Crowd out Voluntary Cooperation

Abstract: In this paper we provide experimental evidence indicating that incentive contracts may cause a strong crowding out of reciprocity-driven voluntary cooperation. This crowding out effect constitutes costs of incentive provision that have been largely neglected by economists. In our experiments the crowding out effect is so strong that the incentive contracts are less efficient than contracts without any incentives. Principals, nonetheless, prefer the incentive contracts because they allow them to appropriate a much larger share of the (smaller) total surplus and are, hence, more profitable for them.

The changing nature of the school-to-work transition process in OECD countries

Abstract: This paper highlights the contrasting trends in youth labour market performance over the past decade using a wide range of indicators. It presents new evidence on the length of transitions from school to work, and the degree to which temporary jobs serve as either traps for young people or stepping-stones to good careers. The paper also reviews some recent policy innovations to improve youth employment prospects.

The Trade Effects of Endogenous Preferential Trade Agreements

Abstract: Recent work by Anderson and van Wincoop (2003) establishes an empirical modelling strategy which takes full account of the structural, non-(log-)linear impact of trade barriers on trade in new trade theory models. Structural new trade theory models have never been used to evaluate and quantify the role of endogenous preferential trade agreement (PTA) membership for trade in a way which is consistent with general equilibrium. Apart from this gap, the present paper aims at delivering an empirical model which takes into account both that preferential trade agreement membership is endogenous and that the world matrix of bilateral trade flows contains numerous zero entries. These features are treated in an encompassing way by means of (possibly two-part) Poisson pseudo-maximum likelihood estimation with endogenous binary indicator variables in the empirical model.
