This paper proposes a model of economy with weakly non-separable preferences for both work effort and consumption. Households who derive utility from consumption of a single commodity and leisure take into account the habitual dependency of their utility on both labour supply and consumption in...

This paper uses a heterogeneous-agent overlapping-generations model to examine the fiscal and distributional consequences of introducing a means test in US Social Security. I find that a means test, that is, conditioning benefit payments on a household's earnings or assets, leads to a higher...

This paper proves that the income theories by Hicks and Fisher offer insufficient explanation, and that the existing measuring approaches greatly over-estimate income. Instead, it uses Keynes' definition to prove that income is actually profit. Part of the rental, wage and interest receipts is...

This study assesses the economic implications of China's changing population in the 21st century using a numerical general equilibrium model. The simulations show that lower fertility rates yield lower saving rates. Since lower fertility rates reduce the future supply of labor, capital will...

We provide a model with endogenous portfolios of secured and unsecured household debt. Secured debt is collateralized by owner-occupied housing whereas unsecured debt can be discharged according to bankruptcy regulations. We show that the calibrated model matches important quantitative...

We provide a model with endogenous portfolios of secured and unsecured household debt. Secured debt is collateralized by durables whereas unsecured debt can be discharged in bankruptcy procedures. We show that the model matches the main quantitative characteristics of observed wealth and debt...

We reassess the empirical effect of income and employment on self-reported well-being. Our analysis makes use of a novel two-step estimation procedure that allows applying instrumental variable regressions with ordinal observable data. As suggested by the theory of incomplete markets, we...

This paper empirically investigates the effects of changes in the interest rate as well as transitory income uncertainty on households' consumption-savings decision. Applying a structural demand model to German survey data, we estimate the uncompensated interest rate elasticity for savings, in...

Households can rely on private savings or on public unemployment insurance to hedge against the risk of becoming unemployed. These hedging mechanisms are used differently across countries. In this paper, we use a life cycle model to study the effects of unemployment on the portfolio choice of...

We use a life cycle model of consumption and portfolio choice to study the effects of social security on the investment decisions of households for the European case. Our model is mainly based on the one developed by Cocco, Gomes, and Maenhout (2005). We extend it by unemployment risk using...
