Every Economy is a Keynesian Model right now but not to increase the Aggregate Demand but to control the Pandemic. As the saying goes, the rule of war never changes, it's the weapons that change. So post corona as well the law of economic war will remain the same but the arms of price, product, strategies, etc.. will change.
7 Ts that can happen/ may happen post corona are
1 Transformation from traditional organisational structure to the new WFH model (the business models, especially for IT industry, will employ in this manner as understood concerning the recent directive by the Indian government)
2 Technological takeover in different sectors and industries (rise of ethical consumers, the new way of hygiene maintenance and a need for social distancing will lead to innovation, and new technological advancements will happen.
3 Thrifty Investments by both businesses and households (Businesses many of them are incurring huge losses and covering that up they will be very mindful of their investments, as well as households, will watch their expenses as job loss, income cuts and price rise will play a role)
4 Tenacity of employees as job market will transform (The employees will be motivated, efficient and dedicated due to lay off in organisations or tightened opening of vacancies in the market)
5 Tariffs and Taxes on (the exports/imports and community, more restrictions on imports and an expansionary fiscal policy/ expenditure switching policy will aim at increasing the aggregate demand and protecting the domestic producers, sunset industries etc.)
6 Tick size in the financial market (minimum price change in the financial sector). The investors' interest will be protected with new rules.
7 Third Way Political Economic Model (a hybrid of both the left-wing and right-wing politics, a model "beyond left and right", a model that takes in consideration the social justice, neoliberalism as well as capitalism or in simple words a "New Mixed Economy")
All these Ts will mainly relate to Tiger Economies/ Asian Economies. In the long run, the World will opt India for diversified supply chain and manufacturing channels.
