In his seminal paper of 1928, Ramsey conjectured that if agents discounted the future differently, in the long run all agents except the most patient would live at the subsistence level. The validity of this conjecture was investigated in different environments. In particular, it has been...

We study the impact of a fully-funded social security system in an economy with heterogeneous consumers. The unobservability of individual health conditions leads to adverse selection in the private annuity market. Introducing social security — which is immune to adverse selection — affects...

This paper decomposes price into its 2 major constituents, namely markup (Mkp) and marginal cost (MC) with which a Markov-switching VAR with fixed transition probabilities is estimated. Since the proposed pair of variables has not been extensively analysed, a theoretical model that derives...

I model a benevolent planner who motivates a time-inconsistent agent by only committing to provide feedback. The optimal feedback mechanism always takes the simple form of recommending an action. I also provide conditions for when the optimal feedback mechanism takes the simple form of a cutoff....

This paper develops a model showing how the environmental liability regime and the precision of the disclosed environmental performance indicator (EPI) affect managers' incentives (1) to reduce actual pollution and (2) to manipulate the EPI. I assume a company with a separation of ownership and...

We develop a growth model that features the endogenous two-tier innovations of information carrier technology and production technology. Information carrier technology promotes production technology innovation and thus economic growth through improving the preservation and dissemination of...
