Market work per person is roughly 10 percent higher in the U.S. than in Sweden. However, if we include the work carried out in home production, the total amount of work differs by only 1%. I set up a model with home production and show that differences in policy - mainly taxes - can account for...

This paper shows that social security may be an important factor in explaining the equity premium puzzle. In the absence of shortselling constraints, the young shortsell bonds to the middle-aged and buy equity. Social security reduces the bond demand of the middle-aged, thereby restricting the...

This paper shows that improved intergenerational risk sharing in social security may imply very large welfare gains, amounting to up to 15 percent of the per-period consumption relative to the current U.S. consumption. Improved risk sharing raises welfare through a direct effect, i.e., by...

Market work per person is roughly 10 percent higher in the U.S. than in Sweden. However, if we include the work carried out in home production, the total amount of work only differs by 1 percent. I set up a model with home production, and show that differences in policy - mainly taxes – can...

We study voting over education subsidies where poor individuals may be excluded and the rich may chose private alternatives. With plausible changes of the standard game we show that this problem typically has multiple equilibria; one with low taxes, many excluded, and many in private schooling;...

Recent research has been able to measure two forms of technical change---one (fossil) energy-saving and one saving on capital/labor. The results first show strong evidence for "directed technical change" in the sense that the total resources devoted to saving on the inputs responds endogenously...

We estimate an aggregate production function with constant elasticity of substitution between energy and a capital/labor composite using U.S. data. The implied measure of energy-saving technical change appears to respond strongly to the oil-price shocks in the 1970s and has a negative medium-run...

Market work per person is roughly 10% higher in the United States than in Sweden. However, if we include the work carried out in home production, the total amount of work only differs by 1%. I set up a model and show that differences in policy-mainly taxes-can account for the discrepancy in both...
