Is welfare economics still possible, when preferences are endogenously determined? The answer is yes, if and only if the hypothesis of adaptive preferences is correct. If preferences satisfy the conditions of continuity, non-satiation and regularity, then adaptive preferences imply that...

Economic models of climate policy (or policies to combat other environmental problems) typically neglect psychological adaptation to changing life circumstances. People may adapt or become more sensitive, to different degrees, to a deteriorated environment. The present paper addresses these...

We examine the distributional and efficiency impacts of climate policy in the context of fiscal consolidation in a dynamic general-equilibrium overlapping generations model of the US economy. The model includes a disaggregated production structure, including energy sector detail and advanced...

On average, young people underestimate whereas old people overestimate their chances to survive into the future. We employ a subjective survival belief model proposed by Ludwig and Zimper (2013), which can replicate these patterns. The model is compared with hyperbolic discounting within a...

One important parameter in the decision process when buying a private annuity is individuals' subjective life expectancy, because it directly infuences the expected rate of return. We examine the market for private annuities in Germany and evaluate potential selection effects based on subjective...

This paper tests how subjects behave in an intertemporal consumption/saving experiment when borrowing is allowed and whether subjects treat debt differently than savings. Two treatments create environments where either saving or borrowing is required for optimal consumption. Since both...

This paper provides the exact analytical solution for the standard model of endogenous growth when consumers have present-biased preferences and make time-inconsistent savings plans, which they revise continuously. It is shown that long-run growth is not necessarily lower under present-biased...
