The Impact of Turnout on Turning Up: The Complementarity of Attendance among Co-Workers

This paper studies the effects of complementarities in work attendance on absenteeism. It investigates the case where workers, who turn up for work, cover the workload of absent colleagues. Thus, externalities arise from workers being absent from work. The effort workers exert in the workplace is negatively related to worker turnout. Attendance levels of workers are strategic complements, as workers are more likely to turn up when turnout is high. Firms increase wages and improve working conditions in response. In contrast to the more standard shirking literature, the firm sets employment levels higher. Workers may benefit from draconian firing rules.     

Testing poolability in a system of dynamic regressions with nonspherical disturbances

This study analyzes the testing of cross-equation restrictions within a set of regression equations. Through Monte Carlo experiments we examine the actual size of various asymptotic procedures for testing the poolability hypothesis, i.e., equal slope vectors across individual equations. Regression models with both lagged dependent variable regressors and nonspherical disturbances are considered. In these models we find that the performance in finite samples of classical asymptotic test procedures using critical values from either juaw2/xxlarge8497.gif" alt="Fscr" align="MIDDLE" BORDER="0"> or juaw2/xxlarge967.gif" alt="chi" align="MIDDLE" BORDER="0">² approximations is often rather poor. However, employing the original test statistics with bootstrapped critical values leads to much more accurate inference in finite samples. In an empirical analysis of panel data on GDP growth and unemployment rates in OECD countries it is shown that classical asymptotic tests and bootstrap procedures may lead to conflicting test outcomes. I am indebted to Peter Boswijk, Jan Kiviet, Peter Vlaar, the associate editor and 2 anonymous referees for their constructive comments. I want to thank Geoffrey Garrett for kindly making available his data.     

An annual index of Irish industrial production, 1800–1913

We assemble the Irish industrial data currently available for the years 1800–1921, the period during which the entire island was in a political union with Great Britain, and construct an annual index of Irish industrial output for 1800–1913. We also construct a new industrial price index. Irish industrial output grew by an average of 1.3 per cent per annum between 1800 and the outbreak of the First World War. Industrial growth was slightly slower than previously thought, especially during the two decades immediately preceding the Great Famine. While Ireland did not experience absolute deindustrialisation either before the Famine or afterwards, its industrial growth was disappointing when considered in a comparative perspective.
