We study competitive search in goods markets in a heterogeneous-agent monetary model. The model accounts for three stylized facts connecting inflation to consumption inequality, to price dispersion, and to the speed of monetary payments. With competitive search, individuals’ endogenous...

Since the foundational work of Keynes (1936) macroeconomists have emphasized the importance of agents' expectations in determining macroeconomic outcomes Yet in recent decades macroeconomists have devoted almost no effort to modeling actual empirical expectations data instead assuming all...

The study applies a BEKK GARCH-M model to examine the effect of uncertainty on the levels of inflation and output growth in Nigeria. The results suggest a significant positive effect of inflation uncertainty on the level of inflation, supporting the Cukierman and Meltzer (1986) hypothesis. In...

In the late 90's, after severe financial and economic crisis, accompanied by inflation and exchange rate instability, Eastern Europe emerged into two groups of countries with radically contrasting monetary regimes (Currency Boards and Inflation targeting). The task of our study is to compare...

Estimating potential output and the output gap - the difference between actual output and its potential - is important for the proper conduct of monetary policy. However, the measurement and interpretation of potential output, and hence the output gap, is fraught with uncertainty, since it is...

Australia's inflation rate and inflation uncertainty during the post-float era 1983Q3–2006Q4 have acted as important barometers of Australia's macroeconomic performance. The conceptualization and measurement of the nexus between inflation and inflation uncertainty is subject to complex...

In the late 90's, after severe financial and economic crisis, accompanied by inflation and exchange rate instability, Eastern Europe emerged into two groups of countries with radically contrasting monetary regimes (Currency Boards and Inflation targeting). The task of our study is to compare...

This work adds to Lucas (2000) by providing analytical solutions to two problems that are solved only numerically by the author. The first part uses a theorem in control theory (Arrow's sufficiency theorem) to provide sufficiency conditions to characterize the optimum in a shopping-time problem...

This work presents closed-form solutions to Lucas's (2000) general equilibrium expression for the welfare costs of inflation, as well as to the difference between the general-equilibrium measure and Bailey's (1956) partial-equilibrium measure. In Lucas's original work only numerical solutions...

We compute average mark-ups as a measure of market power throughout time and study their interaction with fiscal policy and macroeconomic variables in a VAR framework. From impulse-response functions the results, with annual data for a set of 14 OECD countries covering the period 1970-2007, show...
