Assessing the effect of a compulsory sickness insurance on worker absenteeism

Johansson, Per; Palme, Mårten - Economics Institute for Research (SIR), … - 1998

The effect of economic incentives on worker absenteeism is analyzed using panel data on work absence behavior for each day during 1990 and 1991 (i.e. 730 observations in the time dimension) for a representative sample of 1,396 Swedish blue collar workers. During the observed time period, a major...

Recreational Benefits from Improved Water Quality: A Random Utility Model of Swedish Seaside Recreation

Sandström, Mikael - Economics Institute for Research (SIR), … - 1996

In this paper, a random utility maximization (RUM) model of Swedish seaside recreation is used to estimate the benefits from reduced eutrophication of the seas around Sweden. Sight depth data from around the Swedish coast are used as a quality index related to eutrophication. The model is...

Maximum-likelihood based inference in the two-way random effects model with serially correlated time effects

Karlsson, Sune; Skoglund, Jimmy - Economics Institute for Research (SIR), … - 2000

This paper considers maximum likelihood estimation and inference in the two-way random effects model with serial correlation. We derive a straightforward maximum likelihood estimator when the time-specific component follow an AR(1) or MA(1) process. The estimator is easily generalized to...

How Fast Do Banks Adjust? A Dynamic Model of Labor-Use with an Application to Swedish Banks

Kumbhakar, Subal C.; Heshmati, Almas; Hjalmarsson, Lennart - Economics Institute for Research (SIR), … - 2000

This paper deals with a dynamic adjustment process in which adjustment of a key variable input (labor) towards its desired level is modeled in a panel data context. The partial adjustment type model is extended to incorporate firm- and time-specific adjustment parameter. A flexible (translog)...

Patterns of Productivity Growth in the Norwegian Salmon Farming Industry

Tveterås, Ragnar; Heshmati, Almas - Economics Institute for Research (SIR), … - 1999

This paper is concerned with empirical measurement of patterns of productivity growth by means of competing panel data models of technical change. We argue that short term analysis must rely on models of technical change which are more flexible than the standard time trend model, because...

An Econometric Model of Employment in Zimbabwe's Manufacturing Industries

Heshmati, Almas; Ncube, Mkhululi - Economics Institute for Research (SIR), … - 1998

This paper is concerned with the estimation of an employment relationship and employment efficiency under production risk using a panel of Zimbabwe's manufacturing industries. A flexible labour demand functions are used and consist of two parts: the traditional labour demand function and labour...

The Dynamics of Capital Structure: Evidence from Swedish Micro and Small Firms

Heshmati, Almas - Economics Institute for Research (SIR), … - 2001

Capital structure studies have generally been aimed at studying the determinants of optimal leverage. Empirically, the focus is, however, on studying the association between observed leverage and a set of explanatory variables. This approach has a number of shortcomings. First, the observed...

The Dynamics of Capital Structure

Banerjee, Saugata; Heshmati, Almas; Wihlborg, Clas - Economics Institute for Research (SIR), … - 1999

The common approach in empirical capital structure research has been to study the determinants of optimal leverage by studying the association between observed leverage and a set of explanatory variables. This approach has two major shortcomings. First, the observed leverage need not necessarily...

A long memory panel unit root test: PPP revisited

Andersson, Jonas; Lyhagen, Johan - Economics Institute for Research (SIR), … - 1999

In this paper two techniques, long memory and panel data models, are combined in order to increase the power of unit root tests. The power is shown to be always better against fractional alternatives and usually against autoregressive alternatives. The test is then used to reanalyze data sets...
