This paper assessed the quantitative impact of ambiguity on historically observed financial asset returns and growth rates. The single agent, in a dynamic exchange economy, treats the conditional uncertainty about the consumption and dividends next period as ambiguous. We calibrate the agent's...

We derive a model-free option-based formula to estimate the contribution of market frictions to expected returns (CFER) within an asset pricing setting. We estimate CFER for the U.S. optionable stocks. We document that CFER is sizable, it predicts stock returns and it subsumes the effect of...

This paper analyzes the implementation of Fiscal Rules (FR) in Argentina. Several clear attempts to establish a FR at the national level are identified. The analysis suggests that the environment matters. The only FR that was binding in the period was approved in 2004 during an economic boom,...

We show that some types of fiscal rules can mitigate the well-known procyclical bias in public capital expenditures. Past research has found that fiscal adjustment episodes coincide with large public investment cuts, a pattern we also document in a sample of 75 advanced and emerging economies...

Because of risk aversion, any sensible investment valuation system should value less Projects that contribute more to the aggregate risk, i.e., that have a larger income elasticity of net benefits. In theory, this is done by adjusting discount rates to consumption betas. But in reality, for...

We model investors that take into account the amount of public good that firms produce (e.g., by reducing carbon emissions) when making their portfolio allocation. In an equilibrium asset pricing model with production and public goods provision, we find that environmentally conscious investors...

This paper provides an analysis of the link between the global market for crude oil and oil futures risk premium at the aggregate level. It off ers empirical evidence on whether the compensation for risk required by the speculators depends on the type of the structural shock of interest....

What is the role of financial speculation in determining the real oil price? We find that while macroeconomic shocks have been the major upward driver of the real oil price since the mid 1980s, also financial shocks have sizably contributed since the early 2000s, and at a much larger extent...
