Using data from 116 emerging economies, we show that dollarization remains high even after disinflation, particularly in countries with histories of extreme inflation. We uncover three stylized facts: (i) high inflation episodes are frequent and severe; (ii) they coincide with sharp currency depreciations, triggering shifts to dollar deposits; and (iii) dollarization persists long after inflation stabilizes. Motivated by these facts, we develop a portfolio-choice model where agents allocate between domestic and dollar deposits. We show that although a hedge demand—associated with the observed correlation between inflation and depreciation in low-inflation economies—plays a role, it is not sufficient to generate a positive allocation to dollar deposits. By incorporating inflation disasters and fear of inflation—persistent pessimism shaped by past instability—we account for dollarization's resilience. Together, risk hedging, disaster risk, and belief heterogeneity explain why dollarization persists in low-inflation emerging economies.</div></div>","PeriodicalId":48314,"journal":{"name":"Journal of Economic Dynamics & Control","volume":"180 ","pages":"Article 105194"},"PeriodicalIF":2.3,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145268730","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We address this question in a simplified setting that allows for explicit computation of the learning process: a two-state economy with logarithmic utilities and no background risk. Our first result is that as long as the wealth of the uninformed agents is less than half the aggregate wealth of the economy, the learning process indeed converges to rational expectations. This convergence, however, is non-monotonic, and the market oscillates between phases of excess price volatility and phases of excess volume of trade. The learning process, in addition, is costly for the uninformed agents.

Our model’s computational simulations show that the addition of a dark pool reduces liquidity on the traditional lit exchange. This liquidity reduction is evidenced by longer order execution times and a wider effective spread in the traditional lit exchange, driven by the migration of trading activity to the dark pool. We also identify two opposing channels that influence traders’ performance: the execution delay channel and the price improvement channel. Regarding the execution delay channel, dark orders lead to longer execution times for impatient traders (who seek to trade quickly) and shorter execution times for speculators (who wait for favorable execution prices relative to the asset’s fundamental value). This is because dark orders generally have longer (shorter) execution times than market (limit) orders. Regarding the price improvement channel, dark orders offer more favorable prices for impatient traders than market orders, while dark orders can result in less advantageous pricing for speculators. This is because dark orders are typically executed at the midquote of the bid and ask prices from the limit order market. Ultimately, the effect on execution risk, price improvement, and welfare for both impatient traders and speculators depends on which of these two opposing channels prevails.</div></div>","PeriodicalId":48314,"journal":{"name":"Journal of Economic Dynamics & Control","volume":"179 ","pages":"Article 105163"},"PeriodicalIF":2.3,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144886056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
