The question of whether two drugs - namely alcohol and tobacco - are used as complements or substitutes is of crucial interest if side-effects of anti-smoking policies are considered. Numerous papers have empirically addressed this issue by estimating demand systems for alcohol and tobacco and...

We test whether financial incentives have an effect on weight reduction in a randomized controlled trial involving 700 obese persons assigned to three experimental groups. While two treatment groups obtain €150 and €300, respectively, for achieving an individually assigned target weight...

This paper introduces a novel approach for dealing with the curse of dimensionality in thecase of large linear dynamic systems. Restrictions on the coefficients of an unrestricted VARare proposed that are binding only in a limit as the number of endogenous variables tends toinfinity...

The Peter Principle states that, after a promotion, the observed output of promotedemployees tends to fall. Lazear (2004) models this principle as resulting from a regression tothe mean of the transitory component of ability...

This paper explores theoretically and empirically potentially important yet often-neglectedlinkage between task coordination within the organization and the structure of organizationand bundling of HRMPs (Human Resource Management Practices). In so doing, we alsoprovide fresh insights on the...

This paper considers the statistical analysis of large panel data sets where even afterconditioning on common observed effects the cross section units might remain dependentlydistributed. This could arise when the cross section units are subject to unobserved commoneffects and/or if there are...

Theory predicts that mandated employment protections may reduce productivity by distortingproduction choices. Firms facing (non-Coasean) worker dismissal costs will curtail hiringbelow efficient levels and retain unproductive workers, both of which should affectproductivity. These theoretical...

Based on a German representative sample of employees we explore the relevance anddevelopment of further training in private sector firms. We focus on formal training andexplore possible individual and job-based determinants of its incidence. We also showchanges over time during a 20 year...

Standard search models are unreliable for structural inference of the underlying sources ofwage inequality because they are inconsistent with observed residual wage dispersion. Weaddress this issue by modeling skill development and duration dependence in unemploymentbenefits in a random on the...

This paper analyzes data from a novel field experiment designed to test the impact of twodifferent insurance products and a secret saving device on solidarity in risk-sharing groupsamong rural villagers in the Philippines. Risk is simulated by a lottery. Risk-sharing ispossible in solidarity...
