新会计制度与现行税法的矛盾表现在资产、负债、所有者权益、收入、成本费用支出等各个方面.由于新会计制度与税法施行的目的不同,所以这些矛盾将始终存在.为此,一方面应该同时执行两种法规,另一方面要采取措施尽量缩小两者的矛盾.     

Whose opinion matters when insiders disagree with short sellers?

This study investigates the credibility of conflicting trading signals from two well-informed and sophisticated parties: corporate insiders and short sellers. Our results suggest that insiders’ information is dominant when short sellers trade in the opposite direction. We attribute the positive price reaction following a disagreement to insiders’ superior information that is not available to short sellers. Our results do not support the managerial short-termism argument. Two additional tests show that insider buying credibility enhances when information asymmetry is high and that short sellers reverse their shorting position after the disclosure of insider buying. Both findings support the idea that short sellers may experience a previously unacknowledged barrier in accessing private information.     

Risk premia,asset price bubbles,and monetary policy

We develop a dynamic general equilibrium asset pricing model with heterogeneous beliefs to study the effects of monetary policy on prices, risk premia, asset price bubbles, and financial stability. We propose a new framework for monetary policy with respect to bubbles. Because bubble risk premia arise from an interaction between disagreements among investors and dynamic trading constraints, under a non-accommodative monetary policy, liquidity adjusted risk and bubble risk premia increase. What matters for policy is the trading constrained fraction/mass of agents that disagree about fundamentals (i.e. optimists/pessimists). Accommodative policy can lead to a larger fraction of trading constrained agents that disagree, larger bubbles, and increased systemic risk. An implication of our results is that accommodative monetary policy in response to the Covid-19 crisis does not increase systemic risk due to asset price bubbles, as long as the policy keeps inflation under control.
