We study the effect of a declining labor force on the incentives to engage in labor-saving technical change and ask how this effect is influenced by institutional characteristics of the pension scheme. When labor is scarcer it becomes more expensive and innovation investments that increase labor...

We develop a method that allows one to compute incomplete-market equilibria routinely for Markovian equilibria (when they exist). The main difficulty to be overcome arises from the set of state variables. There are, of course, exogenous state variables driving the economy but, in an incomplete...

We analyse the economic impact of a simultaneous aging shock in two countries. The countries are identical in all respects except the financing scheme of their public pension system. While one relies on capitalization, the other one relies on a pay-as-you-go scheme. We show that the two...

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 which...

This paper shows that the combination of habit formation - present consumption creating additional consumption needs in the future - and myopia may explain why some retirees are forced to 'unretire', i.e., unexpectedly return to work. It also shows that when myopia about habit formation leads to...

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 decisions...

When entering retirement most people face the decision whether they would like their defined contribution account balance paid as a lump sum or to annuitize the amount. The fact that people tend to choose the lump sum even if economic reasons suggest not to is called the annuity puzzle. In a...

Traditionally, quantitative models that have studied households' portfolio choices have focused exclusively on the different risk properties of alternative financial assets. We introduce differences in liquidity across assets in the standard life-cycle model of portfolio choice. More precisely,...

This paper uses stochastic simulations on calibrated models to assess the optimal degree of reliance on funded 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 use a unique dataset on individual retirement decisions in Swiss pension funds to analyze the choice between an annuity and a lump sum at retirement. Our analysis suggests the existence of an 'acquiescence bias', meaning that a majority of retirees chooses the standard option offered by the...
