Targeting Nominal GDP growth by monetary policymakers is equivalent to a restriction on policymaker preferences for an optimality condition derived under rational expectations. This paper reports the results of simulations of a calibrated model comparing Nominal GDP growth targeting with the...

This paper presents a linear-city model where firms compete on price and levels of advertising, which affects the perceived utility of products. More cost efficient firms extend their advantage with more advertising, which leads to higher profits, if advertising is sufficiently effective. We...

Quantity rationing of credit, when some firms are denied loans, has macroeconomics effects not fully captured by measures of borrowing costs. This paper develops a monetary DSGE model with quantity rationing and derives a Phillips Curve relation where inflation dynamics depend on excess...

The new learning dynamic of Brown, von Neuman and Nash (1950) is introduced to macroeconomic dynamics via the cobweb model with rational and naive forecasting strategies. This dynamic has appealing properties such as positive correlation and inventiveness. There is persistent heterogeneity in...

This paper examines a class of interest rate rules, studied in Evans and Honkapohja (2003, 2006), that respond to public expectations and to lagged variables. Their work is extended by considering varying levels of commitment that correspond to varying degrees of response to lagged output. Under...

While ARCH/GARCH equations have been widely used to model financial market data, formal explanations for the sources of conditional volatility are scarce. This paper presents a model with the property that standard econometric tests detect ARCH/GARCH effects similar to those found in asset...

Evolutionary game theory provides a fresh perspective on the prospects that agents with heterogeneous expectations might eventually come to agree on a single expectation corresponding to the efficient markets hypothesis. We establish conditions where agreement on a unique forecast is stable, but...

This paper presents a linear-city model where firms compete on price and levels of advertising, which affects the perceived utility of products. More cost efficient firms extend their advantage with more advertising, which leads to higher profits, if advertising is sufficiently effective. We...

Quantity rationing of credit, when firms are denied loans, has greater potential to explain macroeconomic fluctuations than borrowing costs. This paper develops a DSGE model with both types of financial frictions. A deterioration in credit market confidence leads to a temporary change in the...

This paper uses the momentum threshold autoregressive (MTAR) model and the residuals-augmented Dickey–Fuller (RADF) test to examine the possibility of Evans’ (1991) periodically collapsing bubbles in the equity REIT market. The results are mixed. The MTAR model indicates that overall real...
