摘要:

AbstractWe develop and estimate a simple regenerative optimal stopping model of aircraft engine maintenance that attempts to describe the behaviour of airline maintenance personnel. The model assumes that the decision to send an engine to the shop for overhaul is the solution to a stochastic dynamic programming problem that trades off the expected cost of continuing operation with the attendant risk of engine failure with the cost of performing the overhaul. We estimate the model using 42 engine histories from Pratt&Whitney, Inc. Estimation results indicate that such a model does not explain observed engine histories before deregulation, but does fit the data in the era since deregulation. The model also provides insight into the perceived relative costs of engine maintenance, in‐flight shutdown, and ordinary operatio

摘要:

AbstractThis study provides a Bayesian investigation of rank‐ordered multinominal logit models employing conjugate priors for standard multinomial logit models as well as other priors. Also considered is a specification test of the independence of irrelevant alternatives assumption. The proposed techniques are demonstrated in an empirical investigation of Ontario voter preferences before the 1988 Canadian Federal Electio

摘要:

AbstractThe implications of matching function models for the relationship between labour market tightness and the transition probability into employment are summarized. These implications are then tested using monthly data for three Canadian provinces: British Columbia, Ontario, and Quebec. Testing methods use flexible regression techniques so as to reduce the effect of any extraneous restrictions. The results show rough concordance between theoretical assumptions and empirical facts. Evidence of non‐linearity in the estimated relationships favours a search‐theoretic model of labour markets over one based on queues and some quantitative results offer guidance to those using ‘calibrated’ search models in theoretical a

摘要:

AbstractIn the empirical analysis of unemployment durations and job durations, it is generally assumed that the stochastic processes underlying labour market behaviour and the behaviour concerning participation in a panel survey are independent. However, there are reasons to believe that the probability of dropping out of the panel is related to the rate at which a (different) job is found. If there is such a relation, and if it is ignored, then the estimator of the rate at which individuals become employed or change jobs will generally be inconsistent. In this paper we analyse the relation between the duration spent in a particular labour market state and the duration of panel survey participation, by explicitly modelling and estimating the joint distribution of both durations. The emphasis will be on models allowing for stochastically related unobserved determinants of both types of duration. We estimate models both for unemployment durations and for job durations.

摘要:

AbstractWe augment an ordered response model for the job level at which individuals desire to work with allowance for individual reporting of a discrepancy between actual and desired job level, and we also investigate possible biases from restricting the observations to the employed, and omitting the unemployed. We find that the latter bias can be ignored and interpret this as evidence that the unemployed are not choosier than the employed. People claiming inadequate capability utilization are not markedly differently allocated than those claiming a proper match. Women's lower job levels cannot be explained from rationing by capability utilization.

摘要:

AbstractThis paper investigates the determinants of trade union membership in Australia using the Engle and Granger (1987) theory of co‐integrated economic variables. Applying the theory of co‐integration yields a model of union membership which can be interpreted as distinguishing between long‐run and ‘business cycle’ determinants of union membership. The principal long‐run determinant of union membership is found to be the level of employment disaggregated by industry classification. Business cycle variables—the real wage and the change in unemployment—are also shown to influence movements in union density. These findings are consistent with recent studies which have attributed the decline in union membership in Australia since the early 1980s to the changing composition of employment and movements in the rate

摘要:

AbstractStata 3.1 is a program for data management, graphics, and statistical analysis. Since Version 2.1 was reviewed by Pederson (1991), Stata has added several platforms, third‐party products, supporting services, and many features of interest to econometricians. The result is that Stata 3.1 integrates fast and reliable manipulation of data with high‐powered statistical analysis. For users who do no more than run regressions, the new features do not detract from the feel of ease and control Stata gives the researcher working with any data set, large or small. A unique system to disseminate user‐written programs lets Stata grow continuously without becoming unwieldy, ensuring that Stata will become a standard package in several branches of applied statistics. This review summarizes the hardware requirements of Stata, demonstrates a short but typical Stata session, and discusses some of the unique elements of
