This paper investigates which properties money-demand functions must satisfy so that they are consistent with Lucasís [Lucas, R.E., Jr., 2000. Inflation and welfare. Econometrica 68, 247-274] versions of the Sidrauski and the shopping-time models. We conclude that shopping-time-integrable...

This paper investigates which properties money-demand functions have to satisfy to be consistent with multidimensional extensions of Lucas (2000) versions of the Sidrauski (1967) and the shopping-time models. We also investigate how such classes of models relate to each other regarding the...

This paper shows that in economies with several monies the Bailey–Divisia multidimensional consumers’ surplus formula may emerge as an exact general-equilibrium measure of the welfare costs of inflation, provided that preferences are quasilinear.

This paper uses 1992:1-2004:2 quarterly data and two diferent methods (approximation under lognormality and calibration) to evaluate the existence of an equity- premium puzzle in Brazil. In contrast with some previous works in the Brazilian literature, I conclude that the model used by Mehra and...

The literature on the welfare costs of inflation universally assumes that the many-person household can be treated as a single economic agent. This paper explores what the heterogeneity of the agents in a household might imply for such welfare analyses. First, we show that allowing for a...

We suggest the use of a particular Divisia index for measuring welfare losses due to interest rate wedges and inflation. Compared to the existing options in the literature: i) when the demands for the monetary assets are known, closed-form solutions for the welfare measures can be obtained at a...

Our work is based on a simplified heterogenous-agent shopping time economy in which economic agents present distinct productivities in the production of the consumption good, and differentiated access to transacting assets. The purpose of the model is to investigate whether, by focusing the...

Several works in the shopping-time and in the human-capital literature, due to the nonconcavity of the underlying Hamiltonian, use first-order conditions in dynamic optimization to characterize necessity, but not sufficiency, in intertemporal problems. In this work I choose one paper in each one...

In this work I analyze the model proposed by Goldfajn (2000) to study the choice of the denomination of the public debt. The main purpose of the analysis is pointing out possible reasons why new em pirical evidence provided by Bevilaqua, Garcia and Nechio (2004), regarding a more recent time...

I start presenting an explicit solution to Taylorís (2001) model, in order to illustrate the link between the target interest rate and the overnight interest rate prevailing in the economy. Next, I use Vector Auto Regressions to shed some light on the evolution of key macroeconomic variables...
