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...

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 equity...

We empirically investigate the existence of periodically collapsing bubbles in seven Middle East and North African (MENA) financial markets for the period ending in May 2009. We use the Taylor and Peel (1998) residual augmented least square Dickey and Fuller test (RALS DF) to detect the bubbles....

This study examines the long-run interest rate pass through of the federal funds rate to the prime rate and whether there is asymmetric adjustment in the prime rate using the Enders-Siklos (2001) momentum threshold autoregressive model over the period February 1987 to October 2005. Once...

This paper studies a class of interest rate rules, introduced by Evans and Honkapohja (2001a, 2004), that respond to public expectations and to lagged variables. The policymaker commits to the extent that the interest rate responds to lagged output in an effort to influence public expectations....
