It has been widely debated how much nonsynchronous trading drives asymmetric portfolio cross-autocorrelations: lagged returns on a portfolio of larger-capitalization stocks are far more heavily correlated with current returns on a portfolio of smallercapitalization stocks than the converse. This paper proposes a new method to generate precise estimates of the extent to which nonsynchronous trad...

This paper examines the conditions required to guarantee positive prices in the CAPM. Positive prices imply an upper bound on the equity premium. This upper bound depends on the degree of diversity of firms’ fundamentals, and it is independent of investors’ preferences. In economies with realistically diverse assets the only positive-price CAPM equilibrium theoretically possible is a degenerate...

We analyze a game of persuasion which combines information acquisition and adverse selection. The sender can credibly transmit any information she gathers but cannot directly reveal her type to the receiver. Her payoff depends both on the news content and her perceived ability. We show that a sanitization equilibrium in which the sender reveals good news and conceals bad news prevails for mild ...

In this paper, we develop an agency-theoretic extension of the Lucas asset pricing model and examine the resulting asset price dynamics. In the model, an agent of the firm can expand or contract the firm’s output and dividend payments in response to exogenous shocks, although expansions become increasingly costly for the agent to maintain. Analysis of numerical simulations shows that the time-s...

Recent asset-pricing models incorporate jump risk through Lévy processes in addition to diffusive risk. This paper studies how to detect stochastic arrivals of small and big Lévy jumps with new nonparametric tests. The tests allow for robust analysis of their separate characteristics and facilitate better estimation of return dynamics. Empirical evidence of both small and big jumps based on the...

This paper provides a comprehensive analysis of the short-term interest-rate dynamics based on three different data sets and two flexible parametric specifications. The significance of nonlinearity in the short-rate drift declines with increasing maturity for the interest-rate series used in the study. Using a flexible diffusion specification and incorporating GARCH volatility and non-normal in...

We show how a high degree of commonality in investor liquidity shocks can diminish incentives for intermediaries to keep markets open and lead to market collapse, even without information asymmetry or news affecting fundamentals. We motivate our model using the perpetual floating-rate note market where two years of explosive growth – in which issues by high quality borrowers were placed with in...

This study analyses the information diffusion between Chinese A shares (restricted to domestic investors) and B shares (restricted to foreign investors). The results show that there is an important long-run information diffusion between A and B shares. In the Shanghai stock market, information flows from foreign to domestic investors. However, in the smaller and less liquid Shenzhen stock marke...

Evidence suggests that predictabilities in asset class returns exist but transactions costs prevent exploiting them using individual securities. Extant research also shows that these relationships may by exploitable through the trading of mutual funds but fails to examine whether this relationship exists within an individual fund family. This paper finds that TIAA/CREF retirement annuities exhi...

We model sovereign debt in the absence of a bankruptcy code. Threat of trade sanctions and seizure of exports by the lenders are the drivers of enforcement of sovereign debt contracts.The borrower takes these potential actions into account when choosing optimal voluntary default and debt capacity. We obtain a closedform solution for the sovereign yield spreads that depend on the costs of sancti...
