We study a model of tax evasion, where a flat-rate tax only finances the provision of public goods. Deciding on reported income, each individual takes into account that the less he reports, the higher is his private consumption but the lower is his moral satisfaction. The latter depends on his...

We propose a nonparametric approach to multiple calibration of numerical general equilibrium models, where counterfactual equilibria are solutions to the Walrasian inequalities. We present efficient approximation schemes for deciding the solvability of Walrasian inequalities

We study an optimal robust monetary policy for a small open economy. The robust control approach assumes that economic agents cannot assign probabilities to a set of plausible models and rather focuses on the worst possible misspecification from a benchmark model. Our findings suggest that,...

This paper investigates the learnability of an equilibrium where agents formulate their forecasts under adaptive learning with heterogeneously misspecified econometric models; the equilibrium is called a Heterogeneous Misspecification Equilibrium (HME). The paper finds that the learnability...

This paper studies the relation between the credit-to-GDP ratio and macroeconomic trends. We estimate a long run equation on a sample of EU countries; our findings suggest that the macroeconomic factors with which the credit ratio associates most strongly are economic development, the investment...

This paper provides a general procedure to estimate structural vector autoregressions. The algorithm can be used in constant or time-varying coefficient models, and in the latter case, the law of motion of the coefficients can be linear or non-linear. It can deal in a unified way with...

We apply recently developed early warning indicators systems to a cross-section of emerging markets. We find that, with little or no modification, models designed to predict asset price booms/busts in advanced countries may be useful for emerging markets. The concept of monitoring a set of asset...

This paper tests the ability of popular New Keynesian models, which are traditionally used to study monetary policy and business cycles, to match the data regarding a key channel for monetary transmission: the dynamic interactions between macroeconomic variables and their corresponding...
