Starting from a linear error correction model the stability and linearity of a German M1 moneyt demand function are investigated, applying smooth transition regression techniques. Using seasonally unadjusted data from 1961 (1) to 1990 (2) it is found that the money demand equation is both linear...

Payments in kind pose an enduring and empirically important puzzle. The paper provides a formalization of the popular view that payment in kind are due to financial constraints. The key assumption is that buyers' liquidity is private information. Buyers who are financially constrained may prove...

Indonesia has been severely hurt by the recent economic crisis, which has been accompanied by social tensions. Still, there are reasons to be optimistic about Indonesia's future. The economic crisis may have bottomed out and the difficult transition to democracy has started. For a sustainable...

A purchaser/provider split together with output- based reimbursement were recently introduced by several Swedish county councils. These changes have been motivated by arguments of efficiency and consumer choice. This paper tests the null hypothesis that hospital services are provided as...

We find that contrary to common perception, cooperation as equilibrium of the infinitely repeated discounted prisoner's dilemma is in many relevant cases not very plausible, or at least questionable: for a significant subset of the payoff-discount factor parameter space cooperation equilibria...

Why do money and markets crowd out cooperative relations? This paper characterizes the effects of intertemporal preferences, money, and markets on players' ability to cooperate in material-payoff supergames. Players' aversion to intertemporal substitution facilitates cooperation by decreasing...

This report presents a computer model for evaluating the cost-effectiveness (CE) of Hormone Replacement Therapy (HRT). The model is an extension of a previous model and includes also the risk of spine and wrist fracture. New Swedish data on risk of coronary heart disease and related mortality...

The impact of compulsory schooling laws as well as the abolition of early selection by ability remain important issues in the educational debate. These issues were the focus of a major education reform in Sweden which was implemented in the 60s. The reform was preceded by a ``social experiment''...

Bivariate VAR models are Monte Carlo simulated and OLS estimated, The resulting biases are used to compare two alternative approximations to the bias. They are found to be equivalent for first-order models, whereas for second-order models Nicholls and Pope's approximation outperforms Tjostheim...

We investigate the welfare implications of changing a proportional capital income tax for a model economy in which heterogeneous households face labor income risk and trade only one asset. Labor taxes are adjusted at the time of the reform to maintain long run budget balance. Our stochastic...
