住房供应的市场逻辑与政治悖论:为何我们明明知道答案却无法执行
当一名投资者在社交媒体上以教科书般的逻辑解释住房供应短缺的解法时,他触及了一个尴尬的事实:我们早就知道该怎么做,只是我们不愿意为此付出政治代价。
核心观点:住房可负担性危机的核心并非缺少解决方案,而是政治系统无法承受将正确方案转化为政策所需付出的代价:放弃对市场的微观干预,接受短期阵痛以换取长期供应弹性。
住房危机是一个奇怪的公共政策难题。一方面,它的经济学原理异常清晰:租金反映的是供应与需求的平衡,要降低租金,要么增加供应,要么降低需求。降低需求的途径通常是不受欢迎的——经济衰退会减少就业和人口流入,从而降低住房需求,但这显然不是目标。那么剩下的选择就只有增加供应。这个逻辑如此直白,以至于任何一个经济学入门的学生都能推导出来。然而,当这一逻辑触及政治现实时,它就像撞上了一堵看不见的墙。
一位在社交媒体上分析住房政策的投资者,用一系列简单明了的论点撕开了这层窗户纸。他指出的核心困境是:政府没有能力直接大规模建设住房,因为每套公寓的建设成本在25万到100万美元之间,即使是财力雄厚的城市也无力承担所需的数十万套供应。唯一有能力提供如此规模资本的,是包括养老基金、捐赠基金、保险公司在内的私人投资者网络。但要让这些投资者把钱投进来,必须满足两个条件:一是大幅缩短获得开发许可的时间和复杂性,二是为公寓运营的监管环境提供可预测性。
这两个条件听起来简单,但在政治现实中几乎无法实现。缩短开发许可时间意味着要改革或绕过大量重叠的法规,包括区划法、建筑规范、停车要求、无障碍标准等。这不仅仅是技术性的法规审查,更是对社区自治权力的直接挑战。每一个社区都有一套既得利益结构,通过复杂的审批流程来保护自己的生活方式和房产价值。那些有能力参与审批听证会、有能力发起诉讼来阻止开发的力量,其政治动员能力远超过那些被高昂租金压得喘不过气的普通租房者。
第二个条件——为公寓运营提供可预测的监管环境——更是一个政治雷区。租户筛选限制、驱逐保护、租金控制,这些政策在选民中具有极高的支持率。原因不难理解:没有人希望看到有人因为没有支付租金而被驱逐,也没有人希望自己的租金每年大幅上涨。但投资者看到的是:当这些政策使得运营成本的增长速度超过租金收入的增长速度时,现金流就会萎缩,投资回报率就会下降,资本就会流向其他行业。这并非贪婪,而是基本的财务常识。
反对者会指出,将住房视为纯粹的投资工具本身就是问题的一部分。住房首先是一个栖身之所,是基本人权,不应该被简化为投资回报率计算。这种反对意见有其道德力量,但它忽视了经济学中的一个基本事实:即使我们将住房视为社会权利,它的生产仍然需要调动真实的资源——土地、建材、劳动力、资本——而这些资源在稀缺经济中必然面临着竞争性用途。如果住房投资无法获得与其他投资相当的回报,资本就会流向办公楼、商业地产,或者干脆流向其他国家的房地产市场。那些道德上正确的政策,如果不考虑资本流动的现实,最终只会让住房供应更加短缺。
当前全球住房危机的悖论正在于此:我们拥有解决危机的所有知识,却缺乏实施这些知识的政治意愿。每一个具体的改革措施——取消最低停车位要求、允许在火车站附近建设高密度住宅、简化环境审查流程——在抽象层面都能得到支持,但一旦落实到具体社区,就会遭遇强力的政治抵抗。那些抵抗者并非邪恶,他们只是关心自己的社区品质、房产价值和生活质量,而这些关切在政治上远比供给弹性的概念更容易被理解和动员。
一些城市尝试通过公共住房项目绕过这个矛盾。但政府建设的效率通常低于私人部门,成本控制能力和项目管理能力也相对有限。更重要的是,公共住房通常只能覆盖最迫切的低收入群体,而无法解决中产阶级和年轻专业人士面临的住房可负担性危机。这些人群的收入水平既不符合公共住房的资格标准,又不足以应对市场租金的持续上涨。
一个被低估的因素是文化层面的障碍。在许多城市,高层公寓被视为社区品质的威胁,而不是解决住房短缺的手段。单户住宅区的居民往往将高密度开发与犯罪率上升、学校拥挤、交通堵塞联系在一起,即使研究数据并不支持这些关联。这种文化抵触情绪使得任何增加密度的提案都面临巨大的舆论阻力,政客们自然倾向于搁置争议而不是冒险推动改革。
然而,不改革的代价正在累积。年轻人被迫与父母同住的时间越来越长,中等收入家庭被迫将收入的40%以上用于住房,企业和机构因房屋成本过高而难以吸引人才。这些代价同样具有政治后果,它们以缓慢但持续的方式侵蚀着社会凝聚力和代际公平感。当前的住房危机本质上是一场延迟的代价显化:过去几十年,我们选择用政治便利来替代经济理性,现在账单到期了。
最终,解决住房危机的路径是清晰的,但也是痛苦的。它要求地方、州和联邦层面的政治领袖拥有足够的勇气,去面对那些最激烈反对变革的利益集团,同时教育公众接受一个简单的事实:要让大家住得起,就要让大家接受新的住房被建在自己附近。这从来不是一个经济问题,而是一个关于集体行动与个人利益如何调和的政治问题。而在这个问题上,大多数社会目前仍然在逃避答案。

- RT by @paulg: What every voter and apparently, the NY Times Editorial Board, should know about housing policy:
- 1. Rents reflect the balance of supply of apartments and demand for those apartments in a given area. That’s it; there’s no magic. If you want lower rents, you can hope for a recession that destroys jobs and, therefore, demand. Or you can add supply.
- 2. There is no amount of money that any big city government could feasibly spend that would add materially to supply. This is because, depending on the location, new apartments cost $250,000-1,000,000 to develop… building even a few hundred of those starts to stress any city budget, and many big cities need tens or hundreds of thousands.
- 3. On the other hand, investors (including pension funds and endowments, insurance companies, rich families, etc.) can collectively **easily** provide enough capital to build as much housing as we need **so long as they are confident they can get a reasonable return**.
- To get those investors to fund the creation of the housing our society needs, we must do two things:
- 1. Dramatically reduce the time & complexity associated with securing governmental permission to develop housing. This means reviewing and simplifying the overlapping regulations that constrain housing production: zoning codes, building codes, parking, ADA, etc. But it also means changing the cultures within the relevant governmental agencies from “default no” to “how can we help you?”.
- 2. Provide certainty around on-going regulation of apartment operations.
- The way investors get a return from building rentals is as follows: They hire managers to lease the apartments, collect the rents, pay operating expenses and any mortgage payments, and then send the investors the cashflow that remains.
- But governments all over the country have been restricting the manner in which apartment buildings can be operated in all kinds of ways.
- For example: Cities have been making it harder to screen tenants, while also making it much harder to evict tenants who don’t pay. You can see why both of those measures are politically popular. After all, who doesn’t want people to get second chances? And who wants anyone to get evicted? But, as a manager, the combination of those two regulations makes it much harder to predict, with any certainty, that the rent will get paid… and that makes it very difficult to get investors to provide capital to create more housing.
- Another example: Rent control. Again, I understand why renters love rent control and why politicians want to give it to them. But, if, as has been the case in NY, LA and San Francisco, city governments hold annual rent increases below the rate of growth in the operating expenses of the buildings, the cashflow payable to the investors shrinks… making them much less likely to invest capital in building more apartments.
- In conclusion: For ~every other good or service in the economy, we allow the market to function, and the result is that we have a surplus of choice at all price points (think of food or clothes or cars), which is spectacular for the consumer. If we want a surplus of choice at all price points in housing, we need to get comfortable with the idea of allowing the market to provide it.
- And that means allowing investors to build rental apartments *and* allowing them to operate those apartments in a manner consistent with making a reasonable profit.
- Remember: Every developer of rentals is either a landlord-in-waiting or hoping to sell to one. - https://nitter.net/moseskagan/status/2056394505566466181#m
