Are those countries comparable to Singapore?
Comparable, yes, if they're small, developed, and have relatively low or lower corruption.
Perfectly comparable, no, but that's never true in compensation benchmarking. A board of compensation experts can figure that out.
I don't know what you are trying to say man. If you agree that ceos are not all receiving huge compensation for their work then this must mean the system is working and most are being paid accordingly.
No, there's no logic in that. I pointed out that there are at least outliers in terms of top executive compensation: managers who are merely well compensated (not ridiculously compensated) who generate excellent results. So "always" is not correct. But we could still be talking about outliers in today's world, and that could be a big problem.
Why is there a need for the government to get involved?
Government is already involved, a lot. Corporations are legal constructions, not at all natural.
I don't agree that shareholders have no say when it comes to ceo pay, most shareholders only have no say because they are the minority, the big shareholders are usually institutions and they are mostly fine with the pay unless the ceo is underperforming, nowadays top management pay is paid in the form of options anyway so the share price must perform for them to get paid, a higher sp benefits shareholders so nobody is going to complain.
I disagree. Institutional shareholders routinely complain about their relative lack of oversight power, too. For example, in many jurisdictions it's legal for managers to ignore the expressed wishes of shareholders (big and small) unless they muster a majority of votable shares, not just voted shares. And even then government often allows managers to ignore shareholder votes.
I don't see how benchmarking to other countries is going to help, every country is different, nobody is perfect.
There are lots of reasons why service in the public sector is different than working in the private sector, including the important fact that government isn't supposed to be maximizing profits. Government is supposed to be in the business of maximizing other outcomes, and one would certainly think that the talents required to maximize other outcomes, such as social welfare, are quite different. Yet the Singapore government benchmarks the compensation of ministers against the private sector. I'm arguing that it would be much better to benchmark the compensation of ministers against their peers in small, developed, low corruption countries. Possibly in addition to benchmarking against the private sector, but the private sector is an obviously imperfect comparison given that the KPIs are quite different.
There is no perfect comparison available, no clone of Singapore to benchmark against. All comparisons are imperfect. But, if you're going to benchmark, benchmarking against other small, developed, low corruption countries is a most reasonable choice.
