The growth of shiftwork in the British food,drink and tobacco industries

The authors develop and estimate an econometric model of shiftworking for male, manual employees in the food, drink and tobacco industries. In the demand equations TSLS techniques are used to take account of simultaneity in the determination of shiftworking, capital intensity and plant size. Market demand variables are also incorporated in the model to allow for the distinction between ex ante and ex post decisions to work shifts. A demand variable is also incorporated in the supply equations. The results confirm the diverse economic characteristics of these industries, suggesting that inter-industry studies may conceal a considerable degree of variation at MLH level.

Two–step sequential sampling

Choosing the sample size in advance is a familiar problem: often, additional observations appear to be desirable. The final sample size then becomes a random variable, which has rather serious consequences.
Two such sample extension situations will be considered here. In the first situation, the observed sample variance determines whether or not to double the original sample size. In the second situation, the variances observed in two independent samples are compared; their ratio determines the number of additional observations.     

Corporate mergers and union wage premiums

Corporate mergers possibly enhance the labor negotiation advantage of employers. This study investigates the association between wage levels and merger activity to test the employer bargaining strength hypothesis. The results indicate significantly lower union wages as a consequence of merging. Merger activity, however, does not influence wage levels of non-union workers. These findings are supportive of the employer bargaining strength hypothesis.

Productivity,earnings, and profit sharing — An econometric analysis of alternative models

The theoretical status of the relationship between productivity, wages, and profit sharing (PS) is poor. Only some alternative hypotheses can be formulated. From these explanations six different econometric models are derived. Using data of the German Socio-Economic Panel the models are estimated and tests and indicators are employed to choose the best model. Our investigation speaks in favour of hybrid simultaneous Tobit models where the level of profit sharing is positively correlated with productivity which induces positive wage effects on the one hand. But on the other hand the level of wages is also relevant to the question whether a firm introduces or decides to continuePS and which amount ofPS should be paid.What is obvious is not always true and introspection is a notoriously unreliable guide to empirical magnitudes.

Regulatory incentive policies and abuse

We examine the incentives for abuse under rate-of-return (ROR) and incremental surplus subsidy (ISS) regulation. Abuse consists of expenditures by the regulated firm that provide private benefits, but do not reduce production costs. We show that ISS regulation provides efficient incentives for owners of the regulated firm to limit abuse by subordinates. We also prove that abuse by owners of the firm will generally be greater (smaller) under ROR regulation than under ISS regulation when consumer demand for the regulated product is inelastic (elastic). Furthermore, we show that to limit abuse and improve welfare under ROR regulation, it can be advantageous to ignore available information about consumer demand.     

Labour Market Structure and Inequality: A Comparison of Italy and the U.S.

Markets with rigid labour regulations and centralized wage setting are often thought to be inefficient but egalitarian. Using a model of off-and on-the-job search and event-history, individual-level data for Italy and the U.S., we show that while the cross-sectional wage distributions of young Italian males are much more compressed than are the comparable distributions for young white U.S. males, the estimated search model implies that the distribution of lifetime welfare is no more disperse in the U.S. than it is in Italy. Our model implies that the high frequency of movements between labour market states leads to both a relatively equitable distribution of "long run" welfare in the U.S. and a high level of cross-sectional inequality.     

The Practice Boundaries of Advanced Practice Nurses: An Economic and Legal Analysis

The purpose of this study is to examine the effects of State regulation that determines the extent of professional independence of advanced practice nurses (APNs). We find that in States where APNs have acquired a substantial amount of professional independence, the earnings of APNs are substantially lower, and those of physicians assistants (PAs) are substantially higher, than in other States. These results are striking since PAs are in direct competition with APNs; the only real operational difference between these groups is that PAs are salaried employees who must work under the supervision of a physician. The implication is that physicians have responded to an increase in professional independence of APNs by hiring fewer APNs and more PAs. The finding that earnings of APNs decline when they attain more professional autonomy vis-à-vis physicians reinforces work by Sass and Nichols on physical therapists.The content is the responsibility of the authors and does not represent official positions of the Federal Reserve Bank of St. Louis or the Federal Reserve SystemJEL classification: I11, I18, J31, J44, L51
