The estimation of the PIN model and its extensions has posed significant challenges due to various computational problems. To address these issues, we propose a novel estimation method called the Expectation-Conditional Maximization (ECM) algorithm, which can serve as an alternative to existing...

It is well documented that computational problems may lead to large biases in the estimation of probability of informed trading (PIN) models. While effective remedial solutions have been suggested for the case of original PIN model (Easley et al., 1996), computational problems for its most...

Using earthquake exposure during pregnancy as a proxy for in utero insult, we examine the impact of prenatal stress on investment decisions during adulthood. We find that investors exposed to major earthquakes in utero participate less in the stock market and hold less diversified portfolios,...

The market reaction speeds to the news flow are currently measured at the millisecond level in developed markets. We investigate, using a unique setting from Turkey, whether the market reaction speeds in less sophisticated markets are on par with those of developed markets. We find that market...

This paper examines the impact of vaccination programs on the stock market volatility of the travel and leisure sector. Using daily data from 56 countries over the period from January 2020 to March 2021, we find that vaccination leads to a decrease in the investment risk of travel and leisure...

This paper examines the impact of international soccer matches on the Turkish stock market using firm level and sorted portfolio data, i.e. microeconomic evidence. Applying the Edmans et al. (2007) estimation method, we find a significant negative loss effect. However, once using panel data...

Bansal and Yaron (2004) demonstrate, by calibration, that the Consumption-Based Capital Asset Pricing Model (CCAPM) can be rescued by assuming that consumption growth rate follows a stochastic volatility model. They show that the conditional equity premium is a linear function of conditional...

The COVID-19 pandemic has elevated both the risk and volatility of energy companies. Can mass vaccinations restore stability within this sector? To answer this question, we investigate stock market data from fifty-eight countries from January 2020 to April 2021. We document that vaccination...

This paper examines the impact of international soccer matches on the Turkish stock market using firm level and sorted portfolio data, i.e. microeconomic evidence. Applying the Edmans et al. (2007) estimation method, we find a significant negative loss effect. However, once using panel data...

Behavioral finance literature shows that a variety of mood variables affect the stock prices. Aviation accidents are uncommon that generally cause a high number of casualties. Therefore, they have a strong social repercussion in the country. This negative sentiment driven by bad mood might...
