Agricultural reform in a rural economy, comprising two separable landholding classes is analyzed in an over-lapping generations framework. "The poor" work the land and have children to provide for family labor and old age support. "Landlords" only use hired labor and maximize profits. It is...

In an overlapping generations framework, the effects of exogenous changes in child mortality on fertility and parental welfare in the short run and on fertility, population density and parental welfare in the long run is analyzed in a primitive, land-constrained economy. In a first step a...

A short review of different types of motives in fertility decisions is given, followed by a discussion on the characteristics of societies where the insurance and producer goods motives are important. Three models investigating the effects of different types of policy interventions in such...

In this paper we test for existence of cointegration between health expenditure and GDP using data from 19 OECD countries for the period 1960-1995. Country-by-country and panel results based on the Johansen multivariate likelihood-based inference and a new panel test for cointegration rank are...

The size-wage effect is well documented in the empirical literature, and typical attempts of explanation center on the supply side, using variations of the human capital approach, perhaps combined with institutional theories. With conclusive evidence of its source yet to emerge, an alternative...

Nonnegativety constraints on the parameters of the GARCH (p, Q) model may be relaxed without giving up the requirement of the conditional variance remaining non- negative with probability one. This paper looks into the consequences of adopting these less severe constraints in the GARCH (2,2)...

In this paper, a necessary and sufficient condition for the existence of the unconditional fourth moment of the GARCH (p, q) process is given as well as an expression for the moment itself. Furthermore, the autocorrelation function of the centred and squared observations of this process is...

The paper investigates the redistributive effects of the Swedish health care financing system in 1980 and 1990 for four different financial sources: County council taxes, payroll taxes, direct payments oand state grants. The redistributive effects are decomposed into vertical, horizontal and...

Using a microbased superpopulation approach (see Cassel and Lundquist (1991), (1990))the question of optimal predictors of a population total of AR(1) series is analysed. Only a sample of the individual timeseries in the population is observed. From the sample the population total is predicted....

In this paper we discuss the efficiency properties of insurance markets where supplementary private insurance is allowed to exist together with a compulsory government insurance plan. Our main conclusion, which is contrary to both those of Besley (1989) and Selden (1993), is that in a simple...
