Asset prices and the equity premium might reflect doubts and pessimism. Introducing these features in an otherwise standard New-Keynesian model changes in a quite substantial way its normative conclusions. First, following productivity shocks, optimal policy should be very accommodative even to...

This paper provides first and second-order approximation methods for the solution of non-linear dynamic stochastic models in which the exogenous state variables follow conditionally-linear stochastic processes displaying time-varying risk. The first-order approximation is consistent with a...

Entering a currency union without any political union European countries have taken a gamble: will the needs of the currency union force a political integration (as anticipated by Monnet) or will the tensions create a backlash, as suggested by Kaldor, Friedman and many others? We try to answer...

We present a model where firms compete for scarce managerial talent ("alpha") and managers are risk-averse. When managers cannot move across firms after being hired, employers learn about their talent, allocate them efficiently to projects and provide insurance to low-quality managers. When...

We use quasi-random variation in the fraction of time served in the Italian “open-cell prison” of Bollate to estimate the effect of rehabilitation efforts on recidivism. We deal with the endogeneity of rehabilitation assignments by focussing on those sources of variability in the length of...

It has long been recognized that variations in expected future cash flows are not enough to account for variations in asset prices. Variation in willingness to bear risk is also needed. Asset pricing theories have accordingly focused on models characterized by preferences that allow for time...

While both cultural and legal norms (institutions) help foster cooperation, culture is the more primitive of the two and itself sustains formal institutions. Cultural changes are rarer and slower than changes in legal institutions, which makes it difficult to identify the role played by culture....

We present a model that characterizes the relationship between optimal dynamic cash management and the choice of the means of payment. The novel feature of the model is the sequential nature of the payments choice. In each instant the agent can choose to pay with either cash or credit. This...

We illustrate an intuitive channel through which price stickiness limits the ability of a central bank to improve welfare through stabilization policy. If the central bank uses infl ation to obtain information about nominal spending, sticky prices impair the learning ability of the central bank...

This paper reports on experimental tests of an instantiation of the Lucas asset pricing model with heterogeneous agents and time-varying private income streams. Central features of the model (infinite horizon, perishability of consumption, stationarity) present difficult challenges and require a...
