This paper analyses the risk and return of loans portfolios in a joint setting. I develop a model to obtain the distribution of loans returns. I use this model to describe the investment opportunity set of lenders using mean-variance analysis with a Value at Risk constraint. I also obtain closed...

Excessive levels of firing costs have been consistently blamed for the relatively weak employment in Europe, yet the concusions to be drawn from the literature are somewhat ambiguous. The paper re-examines the impact of adjustment costs under uncertainty.

This paper analyzes the effects of monetary shocks in a DSGE model that allows for a general form of smoothly state-dependent pricing by firms. As in Dotsey, King, and Wolman (1999) and Caballero and Engel (2007), our setup is based on one fundamental property: firms are more likely to adjust...

This paper proposes two models in which price stickiness arises endogenously even though fi rms are free to change their prices at zero physical cost. Firms are subject to idiosyncratic and aggregate shocks, and they also face a risk of making errors when they set their prices. In our fi rst...

The potential negative consequences of high financial volatility have been an important concern recently. Although its empirical relevance has not been proved conclusively, clear theoretic and intuitive arguments justify this concern. Many efforts have been conducted, therefore, to determine...

In this paper, we show that a simple model of smoothly state-dependent pricing generates a distribution of price adjustments similar to that observed in microeconomic data, both for low and high inflation. Our setup is based on one fundamental assumption: price adjustment is more likely when it...

We propose a near-rational model of retail price adjustment consistent with microeconomic and macroeconomic evidence on price dynamics. Our framework is based on the idea that avoiding errors in decision making is costly. Given our assumed cost function for error avoidance, the timing of...

Modern DSGE models are microfounded and have deep parameters that should be invariant to changes in economic policy, so in principle they are not subject to the Lucas critique. But the literature has already established that misspecification issues also cause parameter instability after policy...

We examine the finite-sample performance of small versus large scale dynamic factor models. Our Monte Carlo analysis reveals that small scale factor models out-perform large scale models in factor estimation and forecasting for high levels of cross-correlation across the idiosyncratic errors of...
