Critics within and outside the National Institutes of Health say that NIH's central administration is hostile and defensive and needs to be shaken up. They hope a new director will do just that.     

Estimating Euler equations with noisy data: two exact GMM estimators

In this paper we exploit the specific structure of the Euler equation and develop two alternative GMM estimators that deal explicitly with measurement error. The first estimator assumes that the measurement error is log‐normally distributed. The second estimator drops the distributional assumption at the cost of less precision. Our Monte Carlo results suggest that both proposed estimators perform much better than conventional alternatives based on the exact Euler equation or its log‐linear approximation, especially with short panels. An empirical application to the PSID yields plausible and precise estimates of the coefficient of relative risk aversion and the discount rate. Copyright © 2008 John Wiley & Sons, Ltd.     

Class Size,Teacher Hours and Educational Attainment*

We employ a regression‐discontinuity design to identify effects on educational attainment after compulsory school of class size and the number of pupils per weekly teacher hour using administrative rules as instruments. We use Danish administrative panel data. Average class size is 20, about the same as in the US and most European countries. Restricting the sample to observations close to the enrolment discontinuity points where the administrative rules have greatest predictive power, instrumental variables estimates are consistently negative. Estimates from the preferred specification are marginally significant and indicate modest effects in line with earlier studies. Estimates for subgroups are less precise, but they indicate larger effects for pupils from less advantaged backgrounds.     

Habits and heterogeneity in demands: a panel data analysis

We examine demand behaviour for intertemporal dependencies, using Spanish panel data. We present evidence that there is both state dependence and correlated heterogeneity in demand behaviour. Our specific findings are that food outside the home, alcohol and tobacco are habit forming, whereas clothing and small durables exhibit durability. We conclude that demand analyses using cross‐section data that ignore these effects may be seriously biased. On the other hand, the degree of intertemporal dependence is not sufficiently strong to make composite ‘consumption’ significantly habit forming, as has been suggested in some recent analyses.

A working paper from April 1985: Which demand elasticities do we know and which do we need to know for policy analysis?

This paper presents some results on the theory and estimation of intertemporal allocation mechanisms. The results rely heavily on the distinction between anticipated changes and unanticipated changes.     

Cooperation in a fixed-membership labor-managed enterprise

Conditions are examined under which we can ensure efficiency in a fixed-membership labor-managed firm when the preferences of members over labor and income are unknown. The main result is the derivation of a necessary and sufficient condition on technology that ensures that we can find some reward scheme that gives efficient outcomes. Some commonly suggested reward schemes are examined and it is shown that assumptions that have been used to simplify previous analysis are, in fact, critical to many of the results that have been obtained.     

The long-run cost of job loss as measured by consumption changes

We consider the measurement of the cost of job displacement. With a Canadian panel survey we compare the consumption growth of households that experienced a permanent layoff to a control group of households that experienced a temporary layoff with known recall date. Because the firms employing the latter group are providing insurance, these workers approximate a benchmark of full insurance against job loss shocks. We estimate that permanent layoffs experience an average consumption loss of between 4% and 10%. Older workers and workers with high job tenure have losses closer to the top of this range.     

Realising competitive advantage through HRM in New Zealand service industries

An emerging source of competitive advantage for service industries is the knowledge, skills and attitudes of their employees. Indeed, achievement of a ‘service quality’ culture, considered imperative for competitive advantage in service organisations, supposedly results from the use of best practice human resource management (HRM), and from a strategic approach to their implementation. This paper empirically explores the use of these dimensions of HRM as a source of competitive advantage. It finds high-performing service organisations actively engage best practices across the areas of recruitment and selection, training and development, communication and team working. Evidence of a strategic approach to the implementation of these practices is also found.
