@Oliver_Speaking “Same”

[Mphumzi Makeleni, PhD @Mphuramerciful]

@Oliver_Speaking I was having a conversation with someone, making the sandwich point.

[Mphumzi Makeleni, PhD @Mphuramerciful]

@MalcolmManqoba @penuelist_ In other words, if we are still talking about the same price hike, then no, the same R150 is not “at play” again in one or two weeks. By then, the higher price is simply the prevailing price, as you rightfully asserted.

[Mphumzi Makeleni, PhD @Mphuramerciful]

@MalcolmManqoba @penuelist_ I interpreted your comment as “would the same decision principle apply again later if a similar choice arose?” If you meant “would the same saving from this specific increase still be relevant later?” That would be a different economic scenario altogether.

[Mphumzi Makeleni, PhD @Mphuramerciful]

@Sentletse For others, especially if their opportunity cost of time is high, it is not. There is no contradiction here, only heterogeneous valuations of time, cash flow, and convenience.

[Mphumzi Makeleni, PhD @Mphuramerciful]

@Sentletse The logic is simple: people queue when the expected gain from filling their fuel now exceeds the cost of waiting. The fact that you would not queue only shows that your opportunity cost of time is higher. For some motorists, the saving on a full or near-full tank is worth it.

@Bennito4sure @penuelist_ We can tell someone who has done economics 101… 🤣

[Mphumzi Makeleni, PhD @Mphuramerciful]

@GiraffeDes @penuelist_ Yes, that increases your costs beyond the initial R150.

[Mphumzi Makeleni, PhD @Mphuramerciful]

@MalcolmManqoba @penuelist_ Same interpretation. The logic remains the same. What matters is whether, at that point, the benefit of saving R150 is greater than the cost of the wait. If circumstances differ, the rational choice can differ, even for the same person with the same wealth.

[Mphumzi Makeleni, PhD @Mphuramerciful]

@penuelist_ For example, the same person may decline to queue on a busy workday but join the queue on a quiet weekend. Wealth may be unchanged in both cases; what changes is the opportunity cost of time. Same wealth, different constraints, different valuation.

[Mphumzi Makeleni, PhD @Mphuramerciful]

@penuelist_ Put differently, you value your time more highly than the R150 cost of waiting, thus, skipping the queue is the rational choice. Economically, you are revealing that your willingness to pay to avoid the wait is greater than the saving.

[Mphumzi Makeleni, PhD @Mphuramerciful]

@penuelist_ Therefore, this is just a valuation of your time “given the circumstances”, not a statement about wealth. In a different set of circumstances your valuation can change even if your “wealth” is still the same.

When he is done with the theatrics, he should deal with affordability of electricity. This profit is coming at a back of a 190% increase in electricity since 2014. This increase is as a result of consistent above inflation tariff hikes by Eskom to cover costs. That’s not “profit”

[Department of Electricity and Energy @DOEE_ZA]

{WATCH} 🎥 Minister Kgosientsho Ramokgopa kick starts his ‘Eskom Thank You Tour’ at Lethabo and Grootvlei Power Stations following a commitment he made during the announcement of Eskom’s Financial Performance of a historic profit of R16 billion for the first time in eight years. The Minister is on tour to cascade a message of gratitude on behalf of Government for Eskom’s significant recovery in both operational and financial performance.

This is a point we stressed two years ago. His blame shifting game is incredible though 😅.

We’re waiting on a criminal to dismiss other criminals in the name of justice. It’s a contradiction — criminality cannot be cured by more of the same. Whatever he will do tomorrow will be “perfunctory” at best. Let’s take to the streets!

[Mphumzi Makeleni, PhD @Mphuramerciful]

Oh! Poor Demonic Alliance, like a dog without teeth, your protests lack real bite — both you and President Ramaphosa are muzzled by the interests of capital, leaving little room for genuine independent action.
