We consider a tractable affine stochastic volatility model that generalizes the seminal Heston (1993) model by augmenting it with jumps in the instantaneous variance process. In this framework, we consider options written on the realized variance, and we examine the impact of the distribution of...

This paper discusses issues related to GPU for economic problems. It highlights new methodologies and resources that are available for solving and estimating economic models and emphasizes situations when they are useful and others where they are impractical. Two examples illustrate the...

We discover that letting agents pairwise sequentially exchange at "wrong" prices has a robust effect on prices at convergence. If the initial relative price for a good is cheaper than the equilibrium walrasian price due to initial endowments, the initial excess demand effect pushes resource...

We evaluate the ability of different asset pricing models to explain the flows into VIX ETPs with long volatility exposure. We find no evidence supporting that investors consider systematic risk when they evaluate VIX ETP performance. Instead, investors appear to follow a simple mean reversion...

I construct a novel measure of differences of opinion based on investor holdings data which isolates the type of disagreement that is theoretically predicted to affect prices when assets are bundled or unbundled. Empirically, using the setting of corporate spin-offs, I show that differences of...

With formal theoretical conditions as premise, this study develops a formal empirical structure which facilitates, simultaneously inferences in respect of each of rationality and efficiency of pricing of idiosyncratic risk. Using exactly the same data, the new empirical structure revolves around...

We develop a sequential trade model of Iceberg order execution in a limit order book. The Iceberg-trader has the freedom to expose his trading intentions or (partially) shield the true order size against other market participants. Order exposure can cause drastic market reactions ("market...

We study individual coherent preferences underlying asset prices and propose a set of explicit models for nonlinear V-shaped price pressure utility in a new framework. Coherent preferences are consistent interactive choices between momentum trading and reversal trading in stock market where...

In this paper, we study individual trading behaviors by cumulative trading volume distribution over a price range. We select intraday volume distribution as individual revealed preferences over a price range and determine beliefs by the maximum volume price in stock market. We propose a coherent...

We explore effects of simultaneous price changes for the demand of a group of goods, which we refer to as a compound commodity. Specifically, we consider unit and proportional cost components (e. g., taxes, transportation costs, etc.) imposed on the compound commodity. We find that there is a...
