This paper analyses the political constraints of intergenerational risk sharing. The first result is that the political process generally does not lead to ex ante optimal insurance. The second result is that in a second best political setting PAYG still contributes to intergenerational risk...

This paper analyses the choice between risk-sharing and risk-pooling income-contingent loans for higher education of risk-averse individuals who differ in their ability to benefit from education and inherited wealth. The paper identifies the possible outcomes of a majority vote between the two...

To understand how the welfare state adjusts to economic shocks it is important to explain both the genesis of popular preferences and the institutional incentives of governments to respond to these preferences. This paper attempts to do both, using a general theoretical framework and detailed...

This paper analyses the political constraints of intergenerational risk sharing. The first result is that the political process generally does not lead to ex ante optimal insurance. The second result is that in a second best political setting PAYG still contributes to intergenerational risk...

This paper investigates the role that idiosyncratic uncertainty plays in shaping social preferences over the degree of labor market flexibility, in a general equilibrium model of dynamic labor demand where the productivity of firms evolves over time as a Geometric Brownian motion. A key result...

The availability of technology plays a major role in the feasibility and costs of climate policy. Nonetheless, technological change is highly uncertain and capital intensive, requiring risky efforts in research and development of clean energy technologies. In this paper, we introduce a two-track...

This paper investigates the effects of uncertainty emanating from technological improvements on the optimal lifetime of assets. In does so in a dynamic model in which: a) technological change increases continuously the productivity of producers' durables, b) potential competition induces firms...

Commercializing an emerging technology that employs an immature production process can be challenging, particularly when there are many different sources of uncertainty. In industries with stringent safety requirement, regulatory interventions that ensure safety while maintaining incentives for...

We determine the optimal timing for replacement of an emerging technology facing uncertainty in both the output price and the arrival of new versions. Via a sequential investment framework, we determine the value of the investment opportunity, the value of the project, and the optimal investment...

This paper studies technology adoption in a duopoly where the unbiased technological change improves production efficiency. Technological progress is exogenous and modeled as a jump process with a drift. There is always a Markov perfect equilibrium in which the firm with more efficient...
