Several methods have recently been proposed in the ultra high frequency financial literature to remove the effects of microstructure noise and to obtain consistent estimates of the integrated volatility (IV) as a measure of ex-post daily volatility. Even bias-corrected and consistent realized...

This paper proposes a new method for estimating continuous-time stochastic volatility (SV) models for the S&P 500 stock index process using intraday high-frequency observations of both the S&P 500 index and the Chicago Board of Exchange (CBOE) implied (or expected) volatility index (VIX)....

We carry out a revealed preference analysis of monotone comparative statics. We ask what restrictions on an agent's observed choice behavior are necessary and sufficient to rationalize the data with a preference guaranteeing that choices are always monotone with re- spect to a parameter. We...

This paper explores the incidence and determinants of education‐job vertical mismatch in four non-EU transition economies, namely Armenia, Georgia, Macedonia and Ukraine. It uses cross‐section data from the recent World Bank’s Skills toward Employment and Productivity (STEP) surveys of...

The objective of this study is to design a laboratory experiment to explore the effect of ambiguity on a subject’s search behavior in a finite-horizon sequential search model. In so doing, we employ a strategy to observe the potential trend of reservation points that is usually unobserved. We...

We offer an evolutionary explanation for the favorite-longshot bias in pari-mutuel betting, in a simple evolutionary market model. Because of a positive track take, the expected returns of any strategy stay negative and so any agent must vanish in the long run. Those who bet on favorites lose...

This paper constructs a simple model of endogenous growth with ?financial frictions and ?firm heterogeneity. In the presence of fi?nancial constraints and heterogeneity in pro- duction efficiency of fi?rms, the fi?rms whose efficiency exceeds the cutoff level produce and the entrepreneurs who...

This paper develops a nonparametric analysis for the sharp regression discontinuity (RD) design in which the continuous forcing variable may contain measurement error. We show that if the observable forcing variable contains measurement error, this error causes severe identification bias for the...

We consider a dynamic voluntary advertising model with a duopoly. Firms can use advertising and price as competitive tools where product quality is a given and the market is not fully covered by consumers. Advertising also plays a role as a public good. In this situation, we investigate how...

We study the optimal portfolio choice problem of an investor who is averse to both risk and ambiguity. Using the class of utility functions proposed by Klibano, Marinacci, and Mukerji (2005), we establish a generalized mutual fund theorem, which shows that there are a xed number of mutual funds...
