Using detailed housing data for Japanese cities, we investigate the relationship between the intensity of public housing provision and the housing vacancy rate. Our empirical evidence suggests that they are positively correlated. This pattern is magnified across Japan's major cities, for which public housing construction is given higher priority. A preliminary mechanism analysis implies that this is partly caused by the rigidity of Japan's housing market, which makes the private-sector housing supply less responsive to demand changes.

日本的公共住房供应和住房空缺

使用日本城市的详细住房数据，我们调查了公共住房供应强度与住房空置率之间的关系。我们的经验证据表明它们是正相关的。在日本的主要城市中，这种模式得到了放大，在这些城市中，公共住房建设被放在首位。初步的机制分析表明，这部分是由于日本住房市场的僵化所致，这使得私营部门的住房供应对需求变化的反应较弱。
