これは、何十年もの間、中道の政策論議や主流の経済分析から追放されていたもの、すなわち階級闘争とその経済的帰結が戻ってきたことを意味している。正確には、「経済階級の相対的な力がマクロ経済の結果を変える」、「マクロ経済政策がその相対的な力を傾ける」という、時代遅れの2つの考え方が現れているのかもしれない。

それは、バイデン氏の言葉を借りれば、「従業員のバーゲニングチップ」を強化することで、需要の伸びが期待できる場合には、雇用者が労働生産性と生産量の両方を向上させることができるというものです。

従来の経済学の考え方では、このような可能性を考慮する余地はほとんどありません。標準的なモデルでは、労働者の需要と供給が一致するのは、労働者が生産に対する限界的な貢献度に応じて賃金を支払われる場合です。労働者がより多くの、より良いものを要求したり、政府が労働者に代わって要求したりすると、企業が生産を抑制したがるため、結果として失業や非効率が生じます。

完全雇用型の経済は、こうしたモデルとは逆に、企業オーナーと従業員の間の相対的な力に応じて、あらゆる種類の給与交渉に対応できるのだろうか。企業の生産性は、高い需要圧力に対応できるのか?もしそうであれば、政府の「大きな後押し」によって、インフレ率の上昇を抑えつつ、賃金、雇用、生産性の成長を同時に高めることができるだろうか。バイデノミクスという偉大な実験は、これらの疑問に対する答えを与えてくれるかもしれない。

もし答えが「イエス」であれば、経済的な前提だけでなく、政治的な前提も次々と覆されることになるでしょう。その答えは深く議論されるだろう。

景気が悪くなるたびに、ジョン・メイナード・ケインズへの関心が再燃する。今回は、ケインズと同時代のミハエル・カレツキに注目したい。ポーランドの経済学者であるカレツキは、1943年に発表した論文「完全雇用の政治的側面」の中で、財政出動を簡潔に論じただけでなく、高い需要成長の体制の中で逆説的に大きな利益を得ようとする企業家を含め、企業の利害関係者が完全雇用政策に反対する理由を論じている。

カレッキは3つの理由を挙げている。企業経営者は、政府の活動を嫌う可能性がある。なぜなら、「政府が自らの購入によって雇用を増加させるというトリックを覚えてしまえば、この強力な支配装置(雇用を景況感に依存させる)はその効果を失う」からである。彼らは公共投資を嫌うかもしれないが、それは民間の利潤追求の余地が少なくなることを恐れているからである。下降局面を打開する必要性を認めたとしても、最大限の雇用を維持するための政策には、職場のパワーバランスを変えることになるので反対するかもしれません。

マルクス経済学の専門家でなくても、政治的に動機づけられた推論のリスクを理解することはできます。ビデノミクスが成功すれば、労働者の交渉力を向上させるための財政活動は、好調な時期にも維持されるという強い支持を得るだろう。カレツキは警告した。「このような状況では、大企業と連銀の間に強力な同盟が形成される可能性が高く、彼らはおそらく、この状況が明らかに不健全であると宣言する経済学者を複数見つけるだろう」。これは聞き覚えがありますね。

より良い願望は、カレツキが「完全雇用資本主義」と呼んだものである。階級闘争はゼロサムゲームではなく、労働者の力を高めることで生産性を向上させ、利益を高めることができるのです。

Class conflict is back at the core of economics

Workers' unexpected bargaining power could also help boost the profits of business

"Pay them more". With these three words, President Joe Biden summed up the most surprising outcome of the pandemic: workers seem to have the upper hand against employers thanks to widespread labour shortages. While this sense is strongest in the US, reports of businesses struggling to find staff are heard across much of Europe as well.

We should not get ahead of ourselves. Millions of people are still unemployed or on government-funded furlough schemes. Anecdotes of pay pressures do not amount to systematic and sustained high rates of wage growth. Sectoral spikes in prices are related to supply chain bottlenecks, not salary costs.

So the current perception of labour shortages may be just that. But if evidence builds up that workers are systematically making greater demands of their employers than before, the importance of the shift will be profound.

The fact that nobody predicted it is itself significant. We are still scrambling to understand what is going on. Reports of labour shortages coincide with reports of hardship, especially among low-paid workers. Even within single sectors — such as some UK hospitality sectors — many employers have kept employees on furlough when others are desperate for more hands.

It is possible these mismatches are the transition pains of a great restructuring of the economy, with remote working settling in to stay. Yet workers seem to be less victims than agents of this transition. This contrasts with the past 40 years of labour market restructuring, which has largely been inflicted on workers, not pushed by them.

During the pandemic, stories have abounded of workers determined to say no to work they would previously have resigned themselves to and to hold out for something better. It is not just anecdotal, either. A new study finds that more than one-fifth of US workers — and 30 per cent of under-40s — have seriously considered a career change since the pandemic began.

What this looks like is the return of something that was exiled from centrist policy debate and mainstream economic analysis for decades: class conflict and its economic consequences. To be precise, we may be witnessing the manifestation of two outmoded ideas: that the relative power of economic classes alters macroeconomic outcomes; and that macroeconomic policy tilts that relative power.

A third and novel idea is also being put to the test: that strengthening "employees' bargaining chip[s]", as Biden put it, can encourage employers to increase both labour productivity and output if they expect demand growth to be strong.

Conventional economic thinking has little room for these possibilities. In standard models, the supply and demand for labour match when workers are paid exactly their marginal contribution to production. If they demand more and better — or governments do so on their behalf — the result will be unemployment and inefficiency as businesses prefer to curtail production.

Can a fully employed economy, contrary to those models, be compatible with a whole range of salary bargains between business owners and employees, depending on their relative power? Can companies' productivity respond to high demand pressure? If so, can a "big push" from government increase wages, employment and productivity growth at the same time, with higher but contained inflation? The great experiment of Bidenomics may give us answers to these questions.

If the answers are Yes, they will overturn a series of not just economic assumptions but political ones. They will be deeply contested.

Every downturn rekindles interest in John Maynard Keynes. This one should call attention to Michal Kalecki, Keynes's contemporary. In his 1943 article "Political aspects of full employment", the Polish economist not only set out a succinct argument for fiscal stimulus but also discussed why business interests may oppose full-employment policy, including entrepreneurs who paradoxically stand to make greater profits in a regime of high demand growth.

Kalecki offered three reasons. Business owners may dislike government activism as such, because "once the government learns the trick of increasing employment by its own purchases, this powerful controlling device [of making employment depend on business confidence] loses its effectiveness". They may dislike public investment for fear it leaves less space for private profitmaking. Even if they accept the need to end a downturn, they may oppose policy to maintain maximum employment because it would change the balance of power in the workplace.

One does not have to be a Marxian economist to see the risk of politically motivated reasoning. If Bidenomics succeeds, fiscal activism to improve workers' bargaining power will enjoy strong support to be kept in place through good times too. Kalecki warned: "In this situation a powerful alliance is likely to be formed between big business and rentier interests, and they would probably find more than one economist to declare that the situation was manifestly unsound." That should sound familiar.

A better aspiration is what Kalecki called "full employment capitalism". This will depend on promoting an enlightened view of capital owners' self-interest: far from class conflict being a zero-sum game, productivity incentives from greater worker power can boost profits as well.
