The Australian government implemented several new policy initiatives during 1997--2000, with the stated aim of raising the take-up rate of private health insurance. Taken together, these policy initiatives were quite effective, the proportion of the population with private health insurance cover...

We examine the question of which household members should consume medical services, and in what quantities, by using Japanese household-level data. We employ two key concepts, health risk and income risk, and investigate whether family heads or dependents bear these risks. Health risk is the...

In health economics and health care planning, the observation that age cohorts are generally positively correlated with per capita health expenditures is often cited as evidence that population ageing is the main driver of health care costs. Several recent studies, however, challenge this view....

This paper proposes a test for the existence of placebo effects, as described by the so-called expectancy theory. This theory, which is the dominant medical theory of how placebo effects operate, posits that health outcomes rise in individuals' beliefs about the probability that they are getting...

To understand the consequences of the presence of international safety nets on governments' incentives to undertake reforms, we model IFIs´ interventions as country insurance policies. We find that country insurance (especially when made contingent on negative external shocks) is more likely...

In principal-agent settings with moral hazard, the fact that agents are altruistic vis-a-vis third parties (e.g. their family) modifies incentive costs. We derive sufficient conditions for the principal to benefit from altruism. They bear on how altruism affects the agent's marginal rate of...

This paper examines whether recent international policy initiatives to facilitate financial rescues in emerging market countries have influenced debtors' incentives to access official sector resources. The paper highlights a country's systemic importance as a key characteristic that drives...

This paper extends the principal-agent model to determine the size of the firm as measured by the number of agent hired. Hiring more agents results in benefits and costs to the principal. The benefits are gains from specialization: higher productivity can be achieved if, as the number of agents...

Many people are fired from their jobs for poor performance. However, it is difficult to distinguish whether they are fired because they are not well suited for their job (sorting explanation) or because the firms are trying to provide incentives for effort (incentive explanation). This paper...

In this paper we investigate the principal-multi agent relationship with moral hazard where a risk neutral principal contracts with multiple risk averse agents whose actions are unobservable to the principal. We show that the well--known trade--off between incentive and risk sharing can be...
