This paper tests “Bad Policy” Hypothesis which refers to the Great Moderation in the US. We examine this hypothesis by simulating model based impulse response functions for the both pre-Volcker period and post 1982 period. Deriving and simulating standard New Keynesian DSGE Model explicitly,...

We examine the expectational stability (E-stability) of rational expectations equilibrium under optimal interest rate rules in the context of the standard, "New Keynesian" model of the monetary transmission mechanism. We focus on the case where the monetary authority adds interest rate...

The first chapter of this thesis analyzes how the gossip process can be manipulated by malicious people and the impact of such manipulation on information transmission. In this model, a single piece of information is transmitted via a chain of agents with privately known types. Each agent may be...

I find that the total asset (TA) growth anomaly (Cooper et al. 2008) is a noisy manifestation of the net operating asset (NOA) growth anomaly documented earlier in the accounting literature. To better understand the underlying causes of the growth anomalies, I decompose TA growth into NOA growth...

In this work, I develop a new volatility measure; the volatility implied by price changes in option contracts and their underlyings. I refer to this as implied price change volatility. First, I examine the time series behavior of implied price change volatility and investigate possible moneyness...

This dissertation studies whether stock price reactions to quarterly earnings announcements depend on stock liquidity. Baker and Stein (2004) and Scheinkman and Xiong (2003) develop models showing that liquidity can be affected by investor sentiment or speculative trading. With short-sale...
