- Food: it’s booming shortly before Ramadan & during and after Ramadan, celebrating Eid, performing “Zakat Al Fitr” (the equivalent of Thanksgiving in the US) and the end of fasting by buying all kinds of delicious foods and sweets enough to cater for collective social gatherings designed around “enjoyment of food” and often characterized by excess (thus excessive purchase) to convey generosity and avoid “shortcoming”.
- Cloths & apparel: Only towards the end of Ramadan: mostly the very last few days, because of a general “last-minute mentality” & to enjoy possible retail discounts.
- The advertisement industry: through a thriving TV industry tailored around advertisement, with all kinds of religious & entertaining programs including hosted shows by big brands and more frequent commercial-break interruptions.
- Transportation and airways: Ramadan & Eid are social events encouraging social togetherness by nature. You could also argue that people during day-time in Ramadan reduce their transportation time as a result of preferring to stay home and avoid heat and compensate for this greatly by having a longer (transportation-heavy) social night life.
- Electronics: especially smart-phones and smartphone gadgets. Sales of smart-phone may show rise only towards the end of Ramadan, as a way of “changing old with new”, following the very (religiously taught) tradition of Eid that underlies the habit of the massive buying of new cloths. Or as a result of traditional buying gifts to dear ones.
- Electrical appliances: these are said to be booming too shortly before & during Ramadan, especially refrigerators to provide cooling for saved-up-for-later food, by those who need a new better one and air conditioners to provide comfort in times of abstain from eating food and drinking water (cooling effect) in mostly warm regions.
