We examine stock return predictability of "Out-of-The-Money (OTM) put-to-OTM call trading volume ratio" (OTMPC). Our numerical analysis predicts that informed investors hardly write OTM options because the leverage effect is not sufficient to compensate for transaction costs. OTMPC, thus,...

We document the outcome of an options decimalization pilot on Canada's derivatives exchange. Decimalization improves measures of liquidity and price efficiency. The impact differs by the moneyness of an option and is greatest for out-of-the-money options. In contrast with equity studies,...

We empirically examine the impact of trading activities on the liquidity of individual equity options measured by the proportional bid-ask spread. There are three main findings. First, the option return volatility, defined as the option price elasticity times the stock return volatility, has a...

Bid-ask spreads using intraday data reveal significant sensitivity to European Central Bank (ECB) macro announcements. Effects are strongest for announcements that comprise unexpected information or a change in interest rates, and spreads rise sharply during the minutes surrounding interest rate...

We document widespread violations of stochastic dominance in the one-month S&P 500 index options market over the period 1986-2002. These violations imply that a trader can improve her expected utility by engaging in a zero-net-cost trade. We allow the market to be incomplete and also imperfect...

This study compares liquidity costs of electronic and open outcry hard red winter wheat futures contracts traded side-by-side on the Kansas City Board of Trade. Liquidity costs are considerably lower in the electronic market than in the open outcry market. A new approach is used to estimate...

We examine whether option prices correct for predictable bias in stock prices associated with accounting anomalies. Evidence from put-call parity violations suggests that they do not. Rather, option prices accurately track contemporaneous stock prices. Further analysis suggests that high costs...

We estimate effective spreads and round-trip transaction costs at the Berlin Stock Exchange for the period 1892-1913 using daily stock market returns for a sample of 27 stocks. Our results show that transaction costs at the main stock exchange in a bank-based financial system at the turn of the...

In this paper, we introduce a Transactionally Efficient Market Model, which evolves from the standard efficient market model, encompassing both transaction costs and bid-ask prices. Hence, we delve into how arbitrage makes its way within this complex setting. The main outgrowth of the analysis...
