In this paper, we assume that investors have the same information, but trade due to the evolution of their non-market wealth. Investors rebalance their portfolios in response to changes in their expected non-market wealth, and hence trade. Risky nonmarket wealth is non-hedgeable and independent of market risk, and thus represents an additive background risk. Investors who experience positive sh...

Why do asset price bubbles continue to appear in various markets? This paper provides an overview of recent literature on bubbles, with significant attention given to behavioral models and rational models with frictions. Unlike the standard rational models, the new literature is able to model the common characteristics of historical bubble episodes and offer insights for how bubbles are initiat...

I demonstrate that non-financial corporations act as cross-market arbitrageurs in their own securities. Firms use one type of security to replace another in response to shifts in relative valuations, inducing negatively-correlated financing flows in different markets. Net equity repurchases and net debt issuance both increase when the expected returns on debt are particularly low, or when the e...

This paper investigates whether the degree of predictability can be explained by existing asset pricing models, and provides two theoretical upper bounds on the R-square of the regression of stock returns on predictors for given classes of models of interest. Empirically, we find that the predictive R-square is significantly larger than the upper bounds permitted by well known asset pricing mod...

This paper analyzes the relationship between currency price changes and their expectations. Currency price change expectations are derived with the help of different order flow measures, from the trading behavior of investors on OANDA FXTrade, which is an internet trading platform in the foreign exchange market. We investigate whether forecasts of intra-day price changes on different sampling f...

The paper deals with Alternative Risk Transfer (ART) through securitization of longevity and mortality risks in pension plans and commercial life insurance. Various types of such mortality-linked securities are described including methods of their pricing and real examples (e.g. CATM bonds, longevity bonds, mortality forwards and futures, mortality swaps, and others). Hypothetical calculations ...

This paper attempts to examine the securitization, negotiability and profitability aspects of three types of muèŒrabah instruments; namely, asset-enfaced muèŒrabah instruments, currency-enfaced muèŒrabah instruments representing monetary contributions and currency-enfaced muèŒrabah instruments representing real assets. This paper begins with a distinction between ribŒ (usury) and profit and con...

The present study has made an attempt to discuss the effects of exchange rate volatility and price expectation on maize imports in Iran from 1980 to 2013. In doing so, using the EGARCH technique for time series econometrics, price volatility variables for both exchange rate and final price have been calculated, and the time series for these variables have been extracted. Additionally, in regard...

This paper investigates the role of scheduled news announcements in explaining the transmission of volatility, both within European markets and across U.S. and European ones. To this end, a novel approach is taken by employing a set of widely followed implied volatility indices. Aggregate, regional, and individual event dummies and surprise measures for U.S. and European news announcements are ...
