We document a nominal stock price effect that is (like momentum) associated with (national) culture. Using the full spectrum of cultural dimensions proposed by Hofstede et al. and the cross-section of stock returns of 41 countries, we not only show a robust predictive and explanatory power of...

Do illegal insiders internalize legal risk? We address this question with hand-collected data from530 SEC investigations. Using two plausibly exogenous shocks to expected penalties, we showthat insiders trade less aggressively and earlier and concentrate on tips of greater value whenfacing...

While investors demand a premium to hold stocks with high illiquidity level and risk, they underreact to stock-level liquidity shocks and idiosyncratic liquidity. Built on Baker and Stein (2004) market liquidity model, this paper: (i) reports a significant relationship between market liquidity...

Investors' return expectations are pivotal in stock markets, but the reasoning behind these expectations remains a black box for economists. This paper sheds light on economic agents' mental models - their subjective understanding - of the stock market, drawing on surveys with the US general...

This paper is concerned with empirical and theoretical basis of the Efficient Market Hypothesis (EMH). The paper begins with an overview of the statistical properties of asset returns at different frequencies (daily, weekly and monthly), and considers the evidence on return predictability, risk...

We show in a simple framework that momentum trading can exist in equilibrium and momentum trading is profitable. Properties of the model fit the empirics well. First, the model captures in a parsimonious manner both short-term overreaction and long-term reversals. Second, it predicts that...

Many postulated relations in finance imply that expected asset returns strictly increase in an underlying characteristic. To examine the validity of such a claim, one needs to take the entire range of the characteristic into account, as is done in the recent proposal of Patton and Timmermann...
