However, the question of how inflation uncertainty should be quantified is an open issue. We assess the informative content of alternative ex ante quantifications of inflation uncertainty by predicting ex post squared inflation forecast errors in an out-of-sample forecasting contest. We find that the average across distinct models' levels of ex ante uncertainty offers a greater predictive content than other uncertainty measures based on the cross-sectional variance of point forecasts, GARCH or stochastic volatility models.

The set of 13 potential predictors is classified in measures of macroeconomic or monetary performance, stock market characteristics and descriptors of capital valuation.

However, the trilemma is silent about a functional description of respective trade-offs for intermediate 'middle ground' policies. Accounting for the entire space of such policies, we study monetary autonomy in an unrestricted and continuous manner for 20 (mostly) developed economies. Evidence suggests that interest rate dependence almost linearly increases with the FX stability indicator under financial openness. Thereby, full independence would require an intensity of FX volatility which policymakers might hardly accept. However, this strong trade-off can be relaxed efficiently by a moderate reduction of financial openness. Hence, such a policy might offer some protection against the global financial cycle and leaves a considerable scope to combine a domestic monetary policy with a reduced FX rate variability.

Using a nationally representative firm survey that covers more than 41,000 firms for the period 2009 − 2013, we estimate the impact of provincial financial development on the growth rates of firms by accounting for sectoral differences in growth opportunities. We find that province-level financial development promotes the growth rates of sales, investment and sales per worker of small firms, and reduces the growth rate of the wage-to-sales ratio. Our results imply that firms grow faster in provinces with a higher level of financial development. Moreover, the effect of financial development on growth rates is larger when firms operate in sectors with better growth opportunities."],["dc.description.sponsorship"," German Research Foundation 10.13039/501100001659"],["dc.identifier.doi","10.1080/13547860.2022.2109379"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/113703"],["dc.language.iso","en"],["dc.notes.intern","DOI-Import GROB-597"],["dc.relation.eissn","1469-9648"],["dc.relation.issn","1354-7860"],["dc.relation.orgunit","Wirtschaftswissenschaftliche Fakultät"],["dc.title","Local financial development and the growth of small firms in Vietnam"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
