In this paper, we develop a dynamic political-economic theory of social security. We analytically characterize a Markov perfect equilibrium and find that the interaction between Markovian tax policy and tax distortion on private investment in human capital shapes an intertemporal policy rule,...

This paper provides a theory of financial frictions as a transmission mechanism for news shocks to drive aggregate TFP fluctuations. We show that in an economy calibrated to U.S. data, variations in financial frictions on capital allocation in response to news about future technology can...

We develop a theory of corporate liquidity demand, capturing the fact that a firm's borrowing capacity depends on news on future investment profitability. In our model, bad news on future investment profitability reduces a firm's borrowing capacity and therefore increases the need for internal...

This paper provides a theory of financial frictions as a transmission mechanism for primitive shocks to translate into aggregate TFP fluctuations. In our model, financial frictions distort existing capital allocation across different production units, rather than investment in new capital. News...

In this paper, we show that news on future technological improvement can trigger an immediate economic expansion in a model with financial friction on capital allocation. The arrivial of good news on future technology reduces such frictions and generates significant increase in current Total...
