Based on the APARCH model and two outlier detection methods, we computereliable time series of volatility asymmetry for 49 countries with relatively few ob-servations. Results show a steady increase in the asymmetry over the years for mostcountries. We nd that economic development and market...

The empirical literature on the asset allocation and medical expenditures ofU.S. households consistently shows that risky portfolio shares are increasing inboth wealth and health whereas health investment shares are decreasing in thesesame variables. Despite this evidence, most of the existing...

We propose a mathematical model for one pattern of charts studied in technicalanalysis: in a phase of consolidation, the price of a risky asset goes down times after hitting aresistance level.[....] []

In this paper, we discuss the solvability of backward stochastic differential equations(BSDEs) with superquadratic generators. We first prove that given a superquadraticgenerator, there exists a bounded terminal value, such that the associated BSDEdoes not admit any bounded solution. On the...

Between 1999 and 2007, WR Hambrecht has completed 19 IPOs in the U.S. usingan auction mechanism. We analyze investor behavior and mechanism performance inthese auctioned IPOs using detailed bidding data. The existence of some bids posted athigh prices suggests that some investors (mostly retail)...

We solve for the equilibrium dynamics of information sharing in a large pop-ulation. Each agent is endowed with signals regarding the likely outcome of arandom variable of common concern. Individuals choose the effort with whichthey search for others from whom they can gather additional...

In this article, we study the effect of liquidity risk on the performanceof various hedge fund portfolio strategies. The portfolio strategies in eachhedge fund style are formed by incorporating predictability in: (i) managerialskills, (ii) fund risk loadings, and (iii) benchmark returns. As...

Our paper examines the impact of heterogeneous trading technologies for households onasset prices and the distribution of wealth. We distinguish between passive traders whohold fixed portfolios of stocks and bonds, and active traders who adjust their portfolios tochanges in the investment...

We present a model for the equilibrium movement of capital between markets.Two markets with symmetrically distributed risks are distinguished only by the levelsof capital invested in the two markets. That market with the greater amount of capitalearns lower conditional mean returns....

This paper investigates some common determinants of default probability changes ofindividual firms using Standard & Poor's ratings database. We analyze and quantify the re-sponses of hazard rates to changes in various economic variables, namely financial markets,business cycle and credit...
