This paper uses stochastic simulations on calibrated models to assess the optimal degree of reliance on fun ded pensions and on a particular type of unfunded (PAYG) pension. Surprisingly little is known about the optimal split between funded and unfunded systems when there are sources of...

We present a two-good, two-country overlapping generations model where emissions arise from production and each country has a domestic emission permit system. When one country unilaterally reduces her cap on emissions, her output available for domestic and foreign consumption diminishes more...

This paper studies the design of a nonlinear social security scheme in a society where individuals differ in two respects: productivity and degree of myopia. Myopic individuals may not save “enough” for their retirement because their “myopic self” emerges when labor supply and savings...

This paper presents new evidence on how the annuitization decision is affected by changes in the annuity’s value. We take advantage of an unprecendented change in policy, which in 2004 moderated the super-mandatory Swiss occupational pension scheme: The 20 percent reduction in the rate at...

We incorporate Keeping-up-with-the-Joneses (KUJ) preferences into the Blanchard-Yaari(BY) framework and develop, using an AK technology, a model of balanced growth. In this context we investigate status preference, demographic, and pension policy shocks. We find that a higher degree of KUJ...

We analyse optimal saving of risk-averse households when labour income stochastically jumps between two states. The generalized Keynes-Ramsey rule includes a precautionary savings term. A phase diagram analysis illustrates consumption and wealth dynamics within and between states. There is an...

A healthy financial system encourages the efficient allocation of capital and risk. The collapse of the house price bubble led to the financial crisis that started in 2007. There is a large empirical literature concerning the relation between asset price bubbles and financial crises. I evaluate...

Whole life insurance plays an important role in household saving. However, empirical evidence on its determinants is scarce. This paper studies two natural experiments to identify the effects of tax incentives and bequest motives on life-insurance demand. An unanticipated tax reform in 2000...

An analytical framework is developed to study the repercussions between endogenous capital- and labor-saving technical change and population aging. Following an intuition often attributed to Hicks (1932), I ask whether and how population aging affects the relative scarcity of factors of...

Many economists and policy-makers argue that households do not save enough to maintain an adequate standard of living during retirement. However, there is no consensus on the answer to the underlying question about what this standard should be, despite the fact that it is crucial for the design...
