Bootstrap Methods and Applications in Econometrics - A Brief Survey

This paper provides a brief survey of the bootstrap and its use in econometrics. As an introduction, the paper gives a description of the basics of the method, with a special emphasis on boostrap testing. A fairly large amount of space is devoted to discuss why bootstrap tests provide refinements compared to equivalent asymptotic tests. A series of recent different applications in the econometrics literature is then surveyed, in order to give a picture of this rapidly evolving research field.Bootstrap; Sample Reuse Methods; Simulation Methods

Firms' Financial Policy and Labour Demand: Theory and Evidence

We investigate the influence of financial leverage on firms' hiring decisions in the context of a hierarchy of finance model. The analysis is based on the Euler equation of employment in the presence of convex adjustment costs. We show the empirical implications of firms facing a hierarchy of financial costs, and estimate a linearised version of the model on a large panel of Swedish manufacturing firms. Bootstrap methods are utilised to alleviate some of the estimation problems involved. The empirical findings indicate that the influence of financial leverage on firms' hiring decisions differs significantly between firms in different financial regimes.Employment Determination; Financial Policy; Panel Data

Municipal Labour Demand - Sweden 1988 - 1995

In this paper we investigate the determinants of municipal labour demand in Sweden 1988-1995. Utilising a major grant reform in 1993, through which a switch from mainly targeted to mainly general central government grants occurred, we are able to identify which type of grants that have the largest effects on municipal employment. We find a larger municipal employment elasticity with respect to grants before the reform, implying that the more freedom given to the municipalities, the less they seem inclined to spend on municipal employment. We further find (i) a short run wage elasticity of approximately -0.5 and a long run ditto of approximately -0.9, (ii) a quite sluggish adjustment process: only 60% of the desired change in municipal employment is implemented in the first year, (iii) that the demographic structure is an important determinant of municipal employment, and (iv) that the behavioural pattern is different in "socialist" municipalities.Municipal labour demand; Panel data; Median voter model; Sluggishness

Mixed Logit Estimation of the Value of Travel Time

In this paper we use mixed logit specifications to allow parameters to vary in the population when estimating the value of time for long-distance car travel. Our main conclusion is that the estimated value of time is very sensitive to how the model is specified: we find that it is significantly lower when the coefficients are assumed to be normally distributed in the population, as compared to the traditional case when they are treated as fixed. In our most richly parameterised model, we find a median value of time of 57 SEK per hour, with the major part of the mass of the value of time distribution closely centred around the median value. The corresponding figure when the parameters are treated as fixed is 89 SEK per hour. Furthermore, our finding that the ratio of coefficients in a mixed logit specification differ significantly from the ones in a traditional logit specification is contrary to the results obtained by Brownstone & Train (1996) and Train (1997). Whether the ratios will differ or not depends on the model and the data generating process at hand.Mixed Logit; Simulation Estimation; Value of Time

2004), “The effect of grants and wages on municipal labour demand

Abstract In this paper we investigate the determinants of municipal labour demand in Sweden 1988 -1995. Utilising a major grant reform in 1993, through which a switch from mainly targeted to mainly general central government grants occurred, we are able to identify which type of grants that have the largest effects on municipal employment. We find a larger municipal employment elasticity with respect to grants before the reform, which we interpret as evidence that general grants have less employment effects than specific ones. We further find a short run wage elasticity of approximately À 0.5 and a long run ditto of approximately À 0.9, and a quite sluggish adjustment process: only 60% of the desired change in municipal employment is implemented in the first year.
