Size and Development of the Shadow Economies in Israel and in 36 Highly Developed Countries: What do we (not) know?
The size and development of the shadow economy (and tax evasion) in Israel and in 36 highly developed countries is shown over the period 2004 to 2016. Whereas the size of the shadow economy has been decreasing in Israel and in most OECD countries, the extent of the shadow economies is still sizeable. A critical evaluation of the macro size of the shadow economy of Israel and two other countries is done showing various alternative measures of the shadow economy of these three countries. Incentive-oriented policy measures are needed to reduce the shadow economy and tax evasion: e.g. to exclude firms from public contracting if they are engaged in the shadow economy and/or evade taxes.

A Closer Look at Frequent Traders: Addicted, Angry, Sad, Impulsive and Feeling Isolated
Michal Strahilevitz, Joseph Harvey and Dan Ariely Frequent trading has been shown to have a strong negative effect on performance in the stock market (Odean & Barber 2000). Yet little has been done to investigate possible underlying causes for frequent trading. Our first study uses a survey to examine the relationship between trading frequency and a variety of psychological variables such as impulsivity, overconfidence and the tendency to experience intense positive and negative emotions, both related to trading and in one’s daily lives. While the first study includes a significant number of day traders, our second survey, which is conducted 10 years later, does not. Nevertheless, we replicate the prior findings. In our second study, we also examine a wider range of emotions as well as other factors including social isolation. Combined, the two studies illuminate potential causes and consequences of frequent stock trading. Our findings regarding the psychological issues correlated with frequent trading also suggest that helping investors stop this destructive habit may require more than simply informing them that frequent trading has been found to reduce profits.
