This paper proposes a moment-matching method for approximating vector autoregressions by finite-state Markov chains. The Markov chain is constructed by targeting the conditional moments of the underlying continuous process. The proposed method is more robust to the number of discrete values and...

This paper develops a new theoretical framework, introducing into the traditional real business cycle model a second sector, which we interpret as representing the underground economy. We find that a model with an underground sector is quite successful in matching the stylized facts of the...

This paper investigates the response of the shadow economy to banking crises. Our empirical analysis, based on a large sample of countries, suggests that the informal sector is a powerful buffer, which expands at times of banking crises and absorbs a large proportion of the fall in official...

The non-accelerating inflation rate of unemployment (NAIRU) is not directly observable and the presence of informal workers imposes an additional challenge in its estimation. Countries with large informal sectors, traditional measures might not depict labor slack properly, as it has the wage...

Standard real business cycle models must rely on total factor productivity (TFP) shocks to explain the observed comovement of consumption, investment, and hours worked. This paper shows that a neoclassical model consistent with observed heterogeneity in labor supply and consumption can generate...

We propose a tractable framework that incorporates endogenous default in a continuous time setting and assesses the interaction of default and leverage. In our heterogeneous agent model, productive experts face leverage constraints and aggregate risk, borrow from less productive households and...

This paper proposes to exploit data on expectations to identify news shocks in business cycles. News shocks work through changes in expectations, so data on expectations contain important information for identification. We demonstrate this by estimating a DSGE model augmented with news shocks...

We develop a general-equilibrium model of inventories with explicit micro-foundations by embedding the production-cost-smoothing motive (e.g., Eichenbaum, AER 1989) into an otherwise standard DSGE model. We show that firms facing idiosyncratic cost shocks have incentives to bunch production and...

We develop a N-sector business cycle network model a la Long and Plosser (1983), featuring heterogenous money demand a la Bewley (1980) and Lucas (1980). Despite incomplete markets and a well-defined distribution of real money balances across heterogeneous households, the enriched N-sector...
