Future improvements in mortality are difficult to forecast. In this paper, we incorporate uncertainty about future mortality, or aggregate mortality risk, into an otherwise standard life cycle model with an intertemporal consumption-savings decision. The aggregate mortality process is calibrated...

Traditional power indices are not suited to take account of explicit preferences, strategic interaction, and particular decision procedures. This paper studies a new way to measure decision power, based on fully specified spatial preferences and strategic interaction in an explicit voting game...

This paper studies the links between current accounts and relative price levels, finding that current account changes are associated with sizable future relative price levels effects. This is done in panel regressions of the Penn effect, adding a lagged current account/GDP and other explanatory...

This paper presents a rational expectations model of asset prices with rationally inattentive investors that, unlike previous papers, explains both the substantial amount of equity wealth invested domestically and the puzzling time series behavior of the home bias - an initial plateau before...

This paper evaluates optimal public investment and fiscal policy for countries characterized by limited tax and debt capacities. We study a non stochastic CRS endogenous growth model where public expenditure is an input in the production process, in countries where distortions and limited...

This paper studies how capital market imperfections affect the welfare effects of forming a currency union. The analysis considers a bank-only world where intermediaries compete in Cournot fashion and monitoring and state verification are costly. The first part determines the credit market...

We develop a general equilibrium model of an emerging market economy where productivity growth differentials between tradable and non-tradable sectors result in an equilibrium appreciation of the real exchange ratethe so-called Balassa-Samuelson effect. The paper explores the dynamic properties...

We develop a financial market model focused on fund managers who continuously adjust their exposure to risk in response to the payoff gradient. The base model has a stable equilibrium with classic properties. However, bubbles and crashes occur in extended models incorporating an endogenous...
