Using regret variables, we demonstrate that regret aversion significantly impacts asset pricing. Our empirical results show that investors demand a higher regret premium when holding high-regret assets, and this relationship persists even after controlling for various firm characteristics. By analyzing market states and dynamics, we find that regret aversion is particularly strong in down markets, though its influence weakens in up markets. Market dynamics analysis reveals that regret premiums are most pronounced during simultaneous upward market trends. Robustness tests using cumulative returns and industry-adjusted short-term return reversals further confirm the significant influence of regret on stock returns. Additionally, our analysis of irrational investor behavior, including the disposition effect and psychological price barriers, shows that regret aversion is more pronounced in the context of unrealized capital losses and when asset prices deviate significantly from psychological price barriers. This study provides comprehensive insights into the impact of regret aversion and market dynamics on investor behavior and asset pricing, challenging traditional finance theories grounded in the assumption of rational decision-making.</div></div>","PeriodicalId":46744,"journal":{"name":"Japan and the World Economy","volume":"74 ","pages":"Article 101311"},"PeriodicalIF":1.3,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144069862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Small businesses typically have weaker bargaining power than their customers because they are likely to depend on certain customers. Accordingly, many small businesses face severe constraints in the adjustment of their trade receivables. The Subcontract Act prohibits customer firms from receiving trade credit from small businesses over the long term, and this was enforced more strictly after 2016 following a regulatory revision. This made it easier for small businesses to adjust their trade receivables if their level was considered excessive, serving to enhance the speed of adjustment. We find that trade receivables decreased by an average of 2.1 days following the policy change for the main target firms of the Subcontract Act. Our results also show that small businesses could more rapidly adjust their trade receivables than large firms, both before and after the revision. On this basis, we conclude that while the policy effects on the level of trade receivables are significant, those on the adjustment are not.</div></div>","PeriodicalId":46744,"journal":{"name":"Japan and the World Economy","volume":"74 ","pages":"Article 101310"},"PeriodicalIF":1.3,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143894921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is consistent with the prediction of the buffer stock (Carroll, 1997) that given the nominal interest rate (as has been observed in Japan), higher inflation expectations raise the target ratio when households expect higher inflation to translate into their nominal income in a limited way.

This contrast between Japan and the U.S. is consistent with many studies that attribute the differences in the inflation dynamics between Japan and the U.S. to the monetary policy stance in Japan during the 1970s and early 1980s. Long-term inflation expectations fell to around 2 percent in the late 1980s and remained anchored until the mid-1990s. They fell below 2 percent in the late 1990s, resulting in a low degree of anchoring until the early 2010s.
