Most models of optimal income tax enforcement assume that income is either random or solely remunerates labor, neglecting that auditing strategies may depend on observable inputs. This paper outlines a model to optimally monitor self-employed entrepreneurs when, in addition to reported profits,...

This paper augments a relatively standard dynamic general equilibrium model with financial frictions in order to quantify the macroeconomic effects of the credit deepening process observed in many Latin American (LA) countries in the last decade, most notably in Brazil. In the model, a stylized...

In recent years a large fraction of economies overcame the fear of floating. We study a model that describes the policy of a Central Bank uncertain about whether currency depreciations cause output to expand (textbook model) or contract (balance-sheet model). We conclude that the movement away...

I investigate the optimal auditing scheme for a revenue-maximizing tax-collection agency that observes not only reported prots, but also the level of employment at each firm. Each firm is owned by a single entrepreneur whose managerial ability is random. The optimal auditing scheme is...

This paper introduces cash transfers targeting the poor in an incomplete markets model with heterogeneous agents facing idiosyncratic risk. These transfers change the degree of insurance in the economy and a ect precautionary motives asymmetrically, leading the poorest households to decrease...

We develop a new framework for studying the implementation of monetary policy through the banking sector. Banks are subject to a maturity mismatch problem leading to precautionary holdings of reserves. Through various instruments, monetary policy alters tradeos banks face between lending,...

We use data on immigrants who live in the United States to study the effects of exposure to hyperinflation on occupational choice. To do so, we calculate the number of years an individual had lived under hyperinflation before arriving to the US. We find that its marginal effect on the...

Neste artigo, introduz-se ao modelo de crescimento neoclássico a defasagem necessária para que o investimento público se consolide em capital público (processo time-to-build), assim como alíquotas tributárias distorcivas que se ajustam de acordo com a dívida acumulada pelo setor público....
