6月1日,加拿大央行预计将再次加息,从1.0%升至1.5%。 进步经济学家认为,这无法解决当前通胀压力背后的根本原因,并可能损害我们的经济。 政府还可以采取更多措施来更好地应对价格上涨并避免利率上升的痛苦。
是什么导致了通货膨胀?
20世纪70年代,经济学家认为通货膨胀是由于经济中流动的货币过多造成的。 他们认为降低通货膨胀的唯一方法是保持经济中的货币数量相对稳定。 这种方法称为货币主义。 尽管货币主义在对抗通货膨胀方面基本上没有成功,但它仍然作为一种不肯消亡的僵尸思想而存在。
保守民粹主义者仍然表示,加拿大央行印制过多的钞票导致了通货膨胀。 但事实是,大多数货币是在私人银行向个人和企业放贷时创造的。 不管怎样,货币创造本身并不会引发通货膨胀。 实体经济中的其他因素发挥着更大的作用。
只要供给能够跟上需求,经济中更多的资金就不是问题。 例如,如果有足够的工人和材料来生产某种产品,那么通过在现有设施中增加另一个班次来扩大生产将是很简单的。 但如果工人或扩大生产所需的供应短缺,我们可能会看到长期短缺,从而导致该产品的价格上涨。
虽然大多数通胀分析都集中在需求上,但当前的通胀是由供应短缺和暴利驱动的。 让我们看几个例子。
当商品需求超过商品供应时,就会发生通货膨胀。 有时,这可能是由不可预见的因素造成的,这些因素突然降低了我们经济供应商品的能力。 这种情况发生在大流行期间,当时封锁导致整个全球供应链出现短缺。 同样,俄罗斯入侵乌克兰也影响了粮食、化肥和化石燃料的供应和价格。
需求增长和供应挑战的共同作用也可能刺激通货膨胀。 例如,需求增加和供应链问题导致半导体芯片持续短缺。 这产生了连锁反应,减少了新车的生产数量。 随着新车产量的减少,人们愿意为二手车支付的价格急剧上涨。 不幸的是,半导体短缺及其造成的通胀压力不会很快得到解决。 半导体生产商很少。 事实上,只有两家公司生产了全球供应量的 70%。 建立新的生产成本昂贵,需要高技能的工人,并且需要数月或数年才能完成。
今天的通货膨胀也是由暴利造成的。 Canadians for Tax Fairness研究了加拿大上市公司的财务信息[1],发现2019年至2021年间,它们的平均年销售收入增加了1.745亿美元——但它们的成本仅增加了1690万美元。 这意味着2021年90%的收入增长来自更高的利润率。 缺乏监管、竞争和低企业税率使得企业值得牟取暴利。
尽管当前的通胀是由供应问题和暴利造成的,但各国央行仍在试图通过减少需求来解决通胀问题。 换句话说,央行希望通过减少人们口袋里的钱来解决通货膨胀。 由于央行无法直接从人们手中夺走资金,因此它们通过提高借贷成本来做到这一点。 当利率提高时,借款人就会减少。 结果,私人银行创造的资金减少了。 该理论认为,当流通的货币减少时,经济投资就会减少,失业率就会增加。 理想情况下,这会降低人们的购买力并减缓价格上涨的速度。
问题在于,通过改变利率来改变价格有点像用独木舟桨驾驶游轮。 加拿大央行预计需要两年时间才能充分看到其行动对经济的影响。 过去,央行以更高更快的速度加息,以证明他们致力于降低价格。 这是因为他们的行为唯一直接的影响是对人们的期望。 因此,央行往往会做得太过分,给工人带来很大的困难。
政府如何应对通货膨胀?
目前的经济共识认为,只有央行才能解决通胀问题,政府不应插手干预。 正是由于这种认识,政府常常通过紧缩政策来应对通货膨胀和利率上升。 当加拿大央行提高利率时,各国政府通常不愿花更多钱,因为当加拿大央行试图减少货币供应量时,向经济增加更多资金会适得其反。
与此同时,在通货膨胀时期,政府收入往往会大幅增加。 他们的收入占经济活动的一部分。 随着物价上涨,政府收入也随之增加。 尽管各省政府的收入在 2021 年有所增加,并且在 2022 年也会再次增加,但许多省政府对公共服务的投资仍然不足,并将工资涨幅限制在 1% 至 2% 之间。
政府可以做什么?
面对通货膨胀,财政政策可以发挥很大作用。 从短期来看,重要的是要了解通货膨胀背后的原因,并尝试了解什么可以解决,什么不能解决。 例如,政府应该在短期内帮助修复供应链和运输网络,并思考如何使我们的产业政策能够长期适应未来的挑战。
在通货膨胀时期,政府可以考虑如何为高价物品提供公共替代品。 例如,如果天然气价格长期居高不下,各级政府就应该考虑如何在不需要化石燃料的情况下让出行变得更容易、更便宜。 与央行减少货币供应量的模式相比,这是一种更有针对性、更公平的减少高价商品需求的方式。
政府还可以调节价格。 租金管制就是一个很好的例子。 只要有可能,政策制定者就应该考虑如何维持价格受控商品的供应。 在租金管制的情况下,对非市场和合作住房的公共投资的可靠计划将有助于确保经济适用房的充足供应。
公共服务在让每个人都能负担得起生活方面也发挥着重要作用。 政府在从儿童保育和医疗保健到公共交通和娱乐等各个方面的支出使人们的生活更加负担得起,并使我们所有人都不易受到通货膨胀或经济衰退时期的影响。
这项支出不必通过借贷来资助。 如果政策制定者担心刺激支出会导致利率上升,他们可以用高通胀时期不可避免的收入增加来为这些支出提供资金。 此外,过去 30 年来,加拿大各地政府都为企业和富人减税。 这意味着增加这些税收的空间很大。 央行不会将非借贷资金的支出视为通胀,因此不会促使他们进一步提高利率。 提高企业税率和财富税也将抵消财富集中度和不平等加剧的负面影响。
Raising interest rates won't solve inflation. Here's why.
What's causing inflation?
In the 1970s, economists believed that inflation was caused by too much money floating around in the economy. They thought the only way to lower inflation was to keep the amount of money in the economy relatively constant. This approach is called monetarism. Even though monetarism was largely unsuccessful in combatting inflation, it has stuck around as a zombie idea that refuses to die.
Conservative populists still say the Bank of Canada is causing inflation by printing too much money. But the truth is that most money is created when private banks lend money to individuals and businesses. Either way, money creation isn’t inflationary in and of itself. Other factors in the real economy play a bigger role.
More money in the economy isn’t a problem as long as supply can keep up with demand. For example, if there are enough workers and materials to make to a certain product, it will be straightforward to expand production by adding another shift in an existing facility. But if there is a shortage of workers or the supplies required to expand production, we might see longer term shortages that result in price increases for that product.
While most analyses of inflation concentrate on demand, current inflation is being driven by supply shortages and profiteering. Let’s look at a few examples.
Inflation happens when demand for goods surpasses the supply of goods. Sometimes, this can be caused by unforeseen factors that suddenly reduce our economy’s ability to supply goods. This happened during the pandemic, when lockdowns caused shortages throughout global supply chains. Similarly, the Russian invasion of Ukraine has affected the availability and price of grain, fertilizers, and fossil fuels.
Inflation can also be spurred by a combination of demand growth and supply challenges. For example, increasing demand and problems in the supply chain have resulted in an ongoing shortage of semiconductor chips. This has had a ripple effect by reducing the number of new vehicles that get made. With fewer new vehicles being produced, the price people are willing to pay for a second-hand vehicle has increased dramatically. Unfortunately, the semiconductor shortage, and the inflationary pressures it is creating, will not be solved quickly. There are very few semiconductor producers. In fact, only two companies produce 70% of the global supply. Setting up new production is expensive, requires highly skilled workers, and takes months or years to complete.
Today’s inflation is also being caused by profiteering. Canadians for Tax Fairness studied financial information from publicly traded companies in Canada[1], and found that between 2019 and 2021, their average annual sales revenue increased by $174.5 million – but their costs only increased by $16.9 million. That means that 90% of the increase in revenue in 2021 was from higher profit margins. Lack of regulation, competition, and low corporate tax rates make profiteering worthwhile for corporations.
Even though current inflation is being caused by supply issues and profiteering, central banks are still attempting to address inflation by reducing demand. In other words, central banks want to solve inflation by reducing the amount of money in people’s pockets. Because the central banks can’t take money away from people directly, they do it by making it more expensive to borrow money. When interest rates are raised, there are fewer borrowers. As a result, private banks create less money. The theory is that when less money is circulated, there is less investment in the economy and unemployment increases. Ideally, this reduces people’s purchasing power and slows the rate of price increases.
The problem is that changing prices by changing interest rates is a bit like steering a cruise ship with a canoe paddle. The Bank of Canada expects it to take two years before they fully see the impact of their actions on the economy. In the past, the Bank has increased interest rates higher and faster to prove that they were committed to reducing prices. This is because the only immediate impact of their actions is on people’s expectations. As such, central banks have had a tendency to go too far and cause a great deal of hardship for workers.
How do governments respond to inflation?
The current economic consensus assumes that only central banks can address inflation, and governments should stay out of their way. It is because of this understanding that governments often respond to inflation and interest rate increases with austerity. Governments are generally hesitant to spend more money when the Bank of Canada is increasing interest rates, because it is counterproductive to be adding more money to the economy when the Bank of Canada is trying to reduce the money supply.
At the same time, government revenues often improve significantly during periods of inflation. Their revenue is a proportion of economic activity. As prices rise, so does government revenue. While revenues increased for provincial governments in 2021, and will again in 2022, many are still underinvesting in public services and capping wage increases between 1 and 2 per cent.
What can governments do?
There is a great deal that fiscal policy can accomplish in the face of inflation. In the short term, it is important to understand the causes behind inflation, and try to understand what can and cannot be fixed. For example, governments should be helping to repair supply chains and transportation networks in the short term, and thinking about how to make our industrial policy resilient to future challenges in the long term.
In times of inflation, governments can think about how to provide public alternatives for high priced items. For example, if gas prices are going to be high in the long term, governments at all levels should think about how to make it easier and cheaper to get around without needing fossil fuels. This is a more targeted and equitable way of reducing demand for a high priced good than the central bank model of reducing the money supply.
Governments can also regulate prices. Rent control is a good example of this. Wherever possible, policy makers should think about how to maintain the supply of goods that are price controlled. In the case of rent control, a solid plan for public investment in non-market and co-op housing would help ensure there was sufficient supply of affordable rental housing.
Public services also play a big role in making life more affordable for everyone. Government spending on everything from childcare and healthcare to public transit and recreation makes life more affordable for people, and makes us all less vulnerable to periods of inflation or economic downturns.
This spending does not have to be funded with borrowing. If policy makers are worried about stimulus spending increasing interest rates, they can fund this spending with the revenue increases they inevitably receive during periods of high inflation. In addition, governments across Canada have cut taxes for corporations and the wealthy over the past 30 years. This means that there is significant room to increase these taxes. Spending that is not funded by borrowing will not be considered inflationary by the central banks, and so won’t prompt them to raise interest rates further. Increasing corporate tax rates and taxes on wealth will also counteract the negative impacts of increasing wealth concentration and inequality.
