In particular, the standard solution can deliver misleading results if the deterministic steady state is far from where the model’s stochastic dynamics occur. This problem can be corrected by approximating around the stochastic steady state instead, a strategy that is now easy to implement with standard software thanks to two-parameter perturbation. Using the small open economy model by Fernández-Villaverde et al. (2011, AER) as a laboratory, I find that approximating their model around the stochastic steady state yields much more accurate dynamics, in which the real effect of uncertainty shocks loses quantitative relevance. The reason is that the debt level is much smaller at this point compared to the deterministic steady state, which greatly diminishes the precautionary incentive to reduce outstanding debt in response to riskier interest rates. The results are robust to the choice of emerging economy, the device used to close the model, slight recalibrations that significantly improve the model’s ability to match data, and alternative solution methods. Overall, the findings suggest that, from a theoretical perspective, uncertainty shocks play a significantly smaller role in driving aggregate fluctuations in small open economies than previously thought.</div></div>","PeriodicalId":48314,"journal":{"name":"Journal of Economic Dynamics & Control","volume":"184 ","pages":"Article 105273"},"PeriodicalIF":2.3,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146039642","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}

Specifically, the central bank can achieve at most two out of three policy objectives: attaining the socially efficient allocation, financial stability, and price stability. We show that the central bank can employ a natural policy to evade their concerns. In particular, the central bank can create debt, backed by assets, to provide to patient runners.

In the model, firms overborrow due to pecuniary externalities, where collective investments inflate factor prices, resulting in excessive debt and amplified financial fragility. With interest rate subsidies in sight, firms anticipate cheaper future borrowing and, constrained by collateral limits, reduce current long-term debt to preserve future capacity, curbing overborrowing.

Our model features a benevolent public authority that privately observes her information quality and strategically chooses whether to provide public information to private-sector agents in a beauty-contest game à la Morris and Shin (2002). We show that the authority’s equilibrium strategy hinges on her expected information advantage relative to private-sector agents. When the advantage is either small or large, the authority pools across qualities, and with risk-averse agents, the added uncertainty regarding quality lowers welfare relative to a benchmark without such uncertainty. When the information advantage is intermediate, a separating equilibrium emerges: the high-quality authority provides public information, while the low-quality authority withholds it. In this case, the strategic use of public information enhances welfare by channeling superior information into decisions while limiting overreaction to weak information. By delineating these regimes, we clarify when the social value of strategic public information is beneficial versus detrimental, offering guidance for public communication policies.</div></div>","PeriodicalId":48314,"journal":{"name":"Journal of Economic Dynamics & Control","volume":"183 ","pages":"Article 105250"},"PeriodicalIF":2.3,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145939702","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}

An equilibrium must be unique if the BBK condition holds, or if a Sunspot Admissibility (SSA) condition fails. When SSA holds and the BBK condition fails, multiplicity occurs. These conditions depend on the spectrum of the behavioral expectation operator. I describe how to check these conditions for an arbitrary behavioral expectation, and illustrate with a large variety of popular types of expectations, heuristics, and information frictions.
