This paper proposes asymmetric GARCH-Jump models that synthesize autoregressive jump intensities and volatility feedback in the jump component. Our results indicate that these models provide a better fit for the dynamics of the equity returns in the US and emerging Asian markets, irrespective...

This study examines the relationship between inflation and inflation uncertainty for both developed and emerging countries using the asymmetric power GARCH model. We find new evidence that suggests that positive inflationary shocks have stronger impacts on inflation uncertainty for mainly Latin...

We examine the stability of equilibrium in sunspot-driven real business cycle (RBC) models under adaptive learning. We show that the general reduced form of this class of models can admit rational expectations equilibria that are both indeterminate and stable under adaptive learning....

This paper examines whether favorable information conveyed by stock split announcements transfers to non-splitting firms within the same industry. We find that there exists intra-industry reaction; shareholders of non-splitting firms experience significant positive abnormal returns during the...

Many empirical studies document the value effect. One explanation is that investors overreact to growth aspects for growth stocks. We apply Stein's (1989) method to investigate whether the degree of overreaction differs between value and growth stocks using the implied volatility from option...

We analyze the welfare impact of entrepreneur mobility in a two-country model. Increasing returns in production yield multiple equilibria that are stable under adaptive learning. Governments compete for the mobile resource by setting income taxes. We show that large welfare gains can arise from...

This study provides evidence of a direct relationship between inside spreads and insider trading activity that is stronger when there are fewer market makers or more concentrated market maker market share. No evidence is found of a relationship between quote size at the inside and insider...

We introduce increasing returns to scale into an otherwise standard New Keynesian model with capital, and study the determinacy and E-stability of Taylor-type interest rate rules. With very mild increasing returns supported by empirical research, the conventional wisdom regarding the design of...

We find a positive relation between returns and Book-to Market ratio (BE/ME) and a negative relation between returns and Market Value (MVE) in all the countries we study. The BE/ME and MVE "effects" are international in character and remain strong under a general stochastic pricing function that...

We analyze whether fluctuation in economy-wide factors cause time-series variation in the contracting costs of moral hazard, adverse selection, and financial distress, and so create windows of opportunity for firms to issue debt. Using the announcement period abnormal returns as one measure of...
