I first arrived in the United States with around 10 grand in savings, a box of economics textbooks, and a baggage full of dreams. Unlike many PhD students, I did not initially receive any financial assistance. (1/n)
So the first few months were especially rough. I found the cheapest room I could, traveled by bike, and ate a lot of frozen dinners. But I bled through the savings quickly, mainly because of costly out-of-state tuition fees. (2/n)
But I was very lucky. The family I lived with was exceedingly generous. I ate two meals with them each day, for which I paid only a fraction of the cost. They would invite me to their family holidays. They were kind and wise and supportive. (3/n)
Perhaps the most memorable (but simple) gift I received from them was a cash booklet for McDonald’s, for Christmas. It cost all of 30 bucks. But with that $30, as my American Dad would like to say, he received a lifetime of gratitude and goodwill. (4/n)
For a rich country, Singapore is somewhat unique in that we do not have any foreign aid agency, nor do we grant any form of official development assistance. We do send teams to provide technical support, but we’ve generally eschewed sending financial aid. (5/n)
But our unwillingness to expand our international footprint has a cost. When our neighbors develop, they spend more on goods and services, including on imports. Their imports are our exports. And richer countries buy higher-value goods, which we are more likely to produce. (6/n)
So we do well when they do well. But spending more on global institutions also increases our soft power. Countries like the Netherlands and Sweden and the UAE understand this, as they leverage their aid dollars and UN staff to exercise a disproportionately large footprint. (7/n)
For a rich country, giving is a moral imperative. As citizens of a global village, reciprocity & altruism should be part of our moral fiber. We are taught from a young age to share, and this should extend to foreign relations, because there is value in being good neighbors. (8/n)
Of course, charity begins at home. Many of our workers are still hurting, especially in crisis times. We should help others, only after taking care of ourselves. But we should never forget that generosity has its own reward, even if it only pays off over time. (9/n)
I hope that, as an advanced economy, we can institutionalize our foreign aid efforts. Set up a high-quality aid agency. Send more Singaporeans to stints in international bodies, to observe globalism in action & make it work better for us. Form an intl volunteer corps. (10/n)
I’m in a better financial position these days, and so when we visit the States, I usually pay for our dinners. Nobody’s really counting, but that $30 has probably paid for itself many times over. That’s the power of generosity. (n/n)

This pandemic recession has been brutal for many Singaporeans, especially those that have been displaced from long-held jobs. But such displacements predated #COVID-19; technological advances and trade globalization mean this trend is set to continue. (1/n)
This means that what is needed is an end-to-end jobs safety net. At the back end, the Professional Conversion Program and SkillsFuture help workers reskill, while cofinancing via the Jobs Growth Incentive makes it more palatable for employers to take on retrained rookies. (2/n)
But there is more limited support at the front end. Immediately after losing their jobs, there usually isn’t any immediate relief for retrenched workers. While such insurance payouts aren’t huge, they are often very welcome help at a difficult time. (3/n)

I first experienced financial markets as a young boy, going to the stockbroking firm my mother worked at in the evenings and on Saturday morning (Mom often worked late, and we didn’t have a helper until my sister was born, so this was early-80s-style childcare). (1/n)
My first few temporary jobs were also in the back offices of different financial firms. That’s what got me interested in international finance to begin with, a field I would write several theses about and go on to get a PhD. It is my (intelectual) first love. (2/n)
Although I now ply my trade at a university, most of my career has actually been outside of academia; in a think tank, an international financial institution, and a sovereign wealth fund. Each offered a different perspective on financial markets, which I value deeply. (3/n)

Working in a research-focused
institution, one becomes keenly aware of the importance of innovation as a driver of technology and productivity, which in turn is a source of growth and development. (1/n) Image
Indeed, economists widely acknowledge that sustained, long-run growth is only possible with technological improvements. This is the case with old-school (Solow-style) growth models, as well as newer (Romer-type) “endogenous” growth models. (2/n)
But by the same token, economists know remarkably little about what gives rise to innovation. Ideas, of course, but the field is largely silent about the generation of new ideas (other than assuming that they may arrive via some random process). (3/n)

A free rider, as defined in economics, is an individual (or group) that reaps the benefits of the actions of others, without paying the cost (or underpaying for it). It is a form of market failure, and characterizes nonexcludable goods (those whose use cannot be restricted).
In his opening address to the 14th Parliament, PM Lee spoke of a number of issues. Many points he made were thoughtful, and drew on his deep experience in government, and as Prime Minister. I appreciated his insight and candor.
PM Lee also suggested (and I paraphrase) that the argument that voting for the opposition because others will still return the PAP to power is what the economist will associate with being a free rider.

I spent the largest part of my professional career thus far at the @WorldBank. During that time, I was involved in formulating policy for a wide variety of nations, both democratic, and less so. So FWIW, here are some thoughts on the policymaking process in a democratic society.
For good or ill, decisions made by the majority (or representatives of that majority) apply to all citizens in the country. One may individually disagree. If so, the time to debate a policy’s merits is prior to enactment. But once policy becomes law, all are compelled to follow.
It would thus be profoundly undemocratic (and discriminatory) to apply a given policy selectively to a segment of the population, unless of course the segment were the explicit target of the policy (think maternity leave for mothers only, or min wages for the low-income only).

There has been some pushback against the claim, from our #workersparty manifesto, that min wages is sound policy. Let me begin by emphasizing a position I've held from the start: min wages is not unabashedly good policy. But it is a good start that is also evidence-based.
In social sciences, there is seldom unambiguous evidence. Studies can yield different results, which is why continued research is important & policies should be based on the overall literature. That's why I mentioned that many papers since Card-Krueger corroborate its findings.
The best way to aggregate and evalute the totality of results is to rely on meta-analyses, which are studies of studies. Meta-analyses take the existing results out there, and ask if there are systematic conclusions we can draw from the literature. So let's look at these.
