Warren Mosler to Robin Brooks on Japan's Fiscal Situation
Early this morning, I took a break from working on my book to trade text messages with Warren Mosler , the canonical “father” of MMT.
今天一早，我在写书的过程中休息了一下，与现代货币理论“之父”沃伦·莫斯勒（Warren Mosler）交换了短信。
I had been asking for Warren’s thoughts on Japan.
我一直在询问沃伦对日本的看法。
In particular, I wanted to know what he would say to Robin Brooks, a macro analyst who has been arguing that Japan’s rapidly depreciating currency along with sharply higher interest rates on Japanese government bonds (JGBs) tells us that Japan is getting close to a “full-blown debt crisis.”
我特别想知道他会对宏观分析师罗宾·布鲁克斯(Robin Brooks)说些什么。罗宾·布鲁克斯一直认为，日本货币的快速贬值以及日本政府债券(JGB)利率的大幅上升告诉我们，日本正在接近“全面的债务危机”。
Since we were corresponding by text, Warren’s thoughts were brief and incomplete.
由于我们是通过短信通信，沃伦的想法简短且不完整。
So, just for fun, I decided to prompt ChatGPT.
因此，只是为了好玩，我决定提示 ChatGPT。
I asked it to draft a respond to Brooks from the perspective of Warren Mosler.
我要求它从沃伦·莫斯勒的角度起草一份对布鲁克斯的回应。
I could tell right away that it included various statements that Warren would never make.
我立刻就看出其中包括沃伦永远不会发表的各种言论。
In a few places, ChatGPT got things exactly backwards.
在一些地方，ChatGPT 的做法完全相反。
I sent it over to Warren, and he responded, “Lots of errors on my position.
我把它发给沃伦，他回答说：“我的立场有很多错误。
Should I edit/correct?”
我应该编辑/更正吗？”
With his permission, I’m sharing the edited text.
经他许可，我将分享编辑后的文本。
I removed the passages that Warren cut and indicated in bold the new content he added.
我删除了沃伦删减的段落，并用粗体标出了他添加的新内容。
I guess you could say ChatGPT got it about half right (or half wrong).
我想你可能会说 ChatGPT 大约一半正确（或一半错误）。
Anyway, thanks to Warren and I hope this is useful to those of you following the ever-intensifying commentary about a global debt crisis.
不管怎样，感谢沃伦，我希望这对那些关注全球债务危机不断加剧的评论的人有用。
From Warren Mosler’s perspective, Robin Brooks’s diagnosis of Japan rests on a fundamental misunderstanding of how interest rates, currency values, and government debt interact in a monetary system where the state is the issuer of its own currency.
从沃伦·莫斯勒的角度来看，罗宾·布鲁克斯对日本的诊断是基于对利率、货币价值和政府债务如何在国家发行本国货币的货币体系中相互作用的根本性误解。
Start with the core error: Brooks treats higher interest rates as a necessary defense of the currency and as a signal of fiscal stress.
从核心错误开始：布鲁克斯将更高的利率视为货币的必要防御和财政压力的信号。
Mosler has long argued that this logic has the causality exactly backwards.
莫斯勒长期以来一直认为，这种逻辑的因果关系完全是倒退的。
For a currency issuer like Japan, raising policy rates does not ‘tighten’ in the conventional sense.
对于日本这样的货币发行国来说，提高政策利率并不是传统意义上的“紧缩”。
It increases government interest payments to the private sector.
它增加了政府向私营部门支付的利息。
Those payments are an addition to deficit spending, new yen income, credited to bank accounts, which expands net financial assets.
这些付款是对赤字支出和新日元收入的补充，记入银行账户，从而扩大了净金融资产。
Through this interest-income channel, rate hikes are more plausibly inflationary than disinflationary, especially in an economy already operating at or near full capacity.
通过这种利息收入渠道，加息更有可能引发通货膨胀，而不是通货紧缩，尤其是在已经满负荷或接近满负荷运转的经济体中。
In Japan’s case, higher rates raise the yen income of JGB holders, boosting domestic spending power.
就日本而言，较高的利率提高了日本国债持有者的日元收入，从而增强了国内消费能力。
That additional yen spending can weaken the exchange rate, not strengthen it.
额外的日元支出可能会削弱而不是强化汇率。
Brooks interprets yen depreciation alongside rising long-term yields as evidence of a debt crisis.
布鲁克斯将日元贬值和长期收益率上升视为债务危机的证据。
Mosler would respond that Japan cannot be forced into insolvency in yen.
莫斯勒会回应说，日本不能被迫以日元破产。
The Bank of Japan can always settle any yen-denominated obligation by crediting reserve accounts.
日本央行始终可以通过记入准备金账户来结算任何以日元计价的债务。
Rising term yields simply reflect market anticipation of a future policy choice to pay more interest, along with possible investor preference for duration issues, and not a market verdict that Japan is “running out of money.” Furthermore, Japan always has the option to issue only 3-month bills, and not to issue any longer term securities.
定期收益率上升只是反映了市场对未来支付更多利息的政策选择的预期，以及投资者可能对久期问题的偏好，而不是市场对日本“资金耗尽”的判断。此外，日本始终可以选择只发行3个月期票据，而不发行任何长期证券。
Brooks also frames the situation as a trap: raise rates to defend the yen and worsen debt dynamics or keep rates low and suffer currency collapse.
布鲁克斯还将这种情况视为一个陷阱：提高利率以捍卫日元并恶化债务动态，或者保持低利率并遭受货币崩溃。
From Mosler’s view, this trap is imaginary.
在莫斯勒看来，这个陷阱是想象出来的。
Brooks has it backwards.
布鲁克斯搞反了。
The yen, with its floating exchange rate policy, is not defended via higher rates, as it would be with a fixed exchange rate policy.
日元采用浮动汇率政策，不会像固定汇率政策那样通过更高的利率来保护。
Instead, it is depreciated by higher rates.
相反，它会因更高的利率而贬值。
Additionally , Japan’s imports are overwhelmingly real goods priced in global markets, and its export competitiveness improves with a weaker currency.
此外，日本的进口绝大多数是在全球市场定价的实物商品，其出口竞争力随着货币贬值而提高。
Without BOJ intervention, foreign exchange reserves remain constant while the level of the yen expresses indifference levels associated with optimal real terms of trade.
在没有日本央行干预的情况下，外汇储备保持不变，而日元水平则与最佳实际贸易条件无关。
Those reserves are the by-product of BOJ intervention not evidence of financial fragility.
这些储备是日本央行干预的副产品，而不是金融脆弱的证据。
Crucially, higher long-term JGB yields do not “burden” Japan in any operational sense.
至关重要的是，较高的长期日本国债收益率在任何操作意义上都不会给日本带来“负担”。
They represent higher interest income paid to the non-government sector—mostly domestic institutions.
它们代表着支付给非政府部门（主要是国内机构）的更高利息收入。
What Brooks calls a debt crisis is, in Mosler’s framework, a distributional issue at most, not a funding problem.
在莫斯勒的框架中，布鲁克斯所说的债务危机最多是一个分配问题，而不是融资问题。
There is no numerical constraint that can be imposed by bond vigilantes or currency traders.
债券义务警员或货币交易员不能施加任何数字限制。
If inflation becomes excessive, rate hikes only make it worse.
如果通胀过度，加息只会让情况变得更糟。
The appropriate tools vary with the underlying reasons for the increase in the price level.
适当的工具因价格水平上涨的根本原因而异。
In the case of excess demand, for example, which is very rare, fiscal adjustments may be appropriate, which can include interest rate reductions.
例如，在需求过剩的情况下（这种情况非常罕见），财政调整可能是适当的，其中可能包括降息。
Prices can also be the result of regulatory measures and instances of imperfect competition, domestic or foreign, often in the context of public and private indexation, none of which are related to interest rate policy.
价格也可能是国内或国外监管措施和不完全竞争情况的结果，通常是在公共和私人指数化的背景下，而这些都与利率政策无关。
In short, Brooks mistakes symptoms for causes.
简而言之，布鲁克斯错把症状当成原因。
Japan is not trapped by its debt; it is choosing an interest-rate policy that weakens the yen and adds income.
日本并未陷入债务困境；它正在选择一种削弱日元并增加收入的利率政策。
The problem is not that Japan cannot afford higher rates, but that raising them does exactly the opposite of what orthodox theory predicts.
问题不在于日本无法承受更高的利率，而在于提高利率的效果与正统理论的预测完全相反。
