AS US President-elect Donald Trump fills his cabinet, what have we learned about the likely direction and impact of his administration’s economic policy?

To be sure, enormous uncertainties remain. As in many other areas, Trump’s promises and statements on economic policy have been inconsistent.

Trump will take charge of an economy on a strongly upward trend, with third-quarter GDP growing at an impressive annual rate of 3.2 percent and unemployment at 4.6 percent in November.

By contrast, when President Barack Obama took over in 2009, he inherited from George W. Bush an economy sinking into a deep recession. And, like Bush, Trump is yet another Republican president who will assume office despite losing the popular vote, only to pretend that he has a mandate to undertake extremist policies.

The only way Trump will square his promises of higher infrastructure and defense spending with large tax cuts and deficit reduction is a heavy dose of what used to be called voodoo economics.

Decades of “cutting the fat” in government has left little to cut: federal government employment as a percentage of the population is lower today than it was in the era of small government under President Ronald Reagan some 30 years ago.

With so many former military officers serving in Trump’s cabinet or as advisers, it is likely that the US will spend more money on weapons that don’t work to use against enemies that don’t exist. If Trump’s health secretary succeeds in undoing the careful balancing act that underlies Obamacare, either costs will rise or services will deteriorate — most likely both.

During the campaign, Trump promised to get tough on executives who outsource American jobs. He is now holding up the news that the home heating and air conditioning manufacturer Carrier will keep some 800 jobs in my home state of Indiana as proof that his approach works.

Yet the deal will cost taxpayers US$7 million, and still allow Carrier to outsource 1,300 jobs to Mexico. This is not a sound industrial or economic policy, and it will do nothing to help raise wages or create good jobs across the country. It is an open invitation for a shakedown of the government by corporate executives seeking handouts.

Similarly, the increase in infrastructure spending is likely to be accomplished through tax credits, which will help hedge funds, but not America’s balance sheet: such programs’ long track record shows that they deliver little value for money.

The cost to the public will be especially high in an era when the government can borrow at near-zero interest rates.

If these private-public partnerships are like those elsewhere, the government will assume the risks, and the hedge funds will assume the profits.

The debate just eight years ago about “shovel-ready” infrastructure seems to be a distant memory. If Trump chooses shovel-ready projects, the long-term impact on productivity will be minimal; if he chooses real infrastructure, the short-term impact on economic growth will be minimal. And back-loaded stimulus has its own problems, unless it is managed extremely carefully.

If Trump’s pick for US Treasury Secretary, the Goldman Sachs and hedge-fund veteran Steven Mnuchin, is like others from his industry, the expertise he will bring to the job will be in tax avoidance, not constructing a well-designed tax system.

The “good” news is that tax reform was inevitable, and was likely to be undertaken by Speaker of the House Paul Ryan and his staff — giving the rich the less progressive, more capital-friendly tax system that Republicans have long sought. With the abolition of the estate tax, the Republicans would finally realize their long-held ambition of creating a dynastic plutocracy — a far cry from the “equality of opportunity” maxim the party once trumpeted.

Large tax cuts and large expenditure increases inevitably lead to large deficits. Reconciling this with Trump’s promise to reduce the deficit will probably entail a return to Reagan-era magical thinking: despite decades of proof to the contrary, this time the stimulus to the economy brought by tax cuts for the rich will be so large that tax revenues will actually increase.

This story doesn’t end well for Trump’s angry, displaced Rust Belt voters. Unhinged budgetary policies will induce the US Federal Reserve to normalize interest rates faster. Some see incipient inflation (given the low unemployment rate); some believe the long period of ultra-low interest rates has distorted capital markets; and some want to “replenish their ammunition,” so that the Fed can lower interest rates should the economy slow down again.

Trump has argued that the Fed should raise interest rates. The Fed, which took the first step toward normalization in early December, will almost certainly deliver — and Trump will soon regret what he wished for. There’s a good chance that the monetary contraction will outweigh the fiscal stimulus, curbing the Obama growth spurt currently underway.

Higher interest rates will undercut construction jobs and increase the value of the dollar, leading to larger trade deficits and fewer manufacturing jobs — just the opposite of what Trump promised. Meanwhile, his tax policies will be of limited benefit to middle-class and working families — and will be more than offset by cutbacks in health care, education, and social programs.

If Trump starts a trade war — by, say, following through on his vow to impose a 45 percent tariff on imports from China and to build a wall on the US border with Mexico — the economic impact will be even more severe. Trump’s cabinet of billionaires could continue to buy their Gucci handbags and US$10,000 Ivanka bracelets, but ordinary Americans’ cost of living would increase substantially; and without components from Mexico and elsewhere, manufacturing jobs would become even scarcer.

To be sure, a few new jobs will be created, mainly in the lobbying shops along K Street in Washington, DC, as Trump refills the swamp that he promised to drain.

Indeed, America’s bog of legal corruption is likely to reach a depth not seen since President Warren G. Harding’s administration in the 1920s.

There really is no silver lining to the cloud that now hangs over the US and the world.
