We characterize welfare maximizing capital requirement policies in a quantitative macrobanking model with household, firm, and bank defaults calibrated to Euro Area data. We optimize on the level of the capital requirements applied to each loan class and their sensitivity to changes in default risk. We find that getting the level right (so that bank failure risk remains contained) is of foremost importance, while the optimal sensitivity to default risk is positive but typically smaller than under Basel internal ratings based (IRB) formulas. Starting from low levels, savers and borrowers benefit from higher capital requirements. At higher levels, only savers prefer tighter requirements. 相似文献

Existing studies on the fiscal multiplier under imperfect competition assume a symmetric market structure with identical firms. This paper examines the fiscal policy implications of introducing a multisectoral economy, where a composite commodity is offered in many varieties within a market of monopolistic competition and a homogeneous good is produced in a perfectly competitive environment. Within the context of this mixed industrial structure we show that the size of the short-run multiplier crucially depends on the composition of public expenditure chosen by the government. 相似文献

This article investigates fiscal convergence attained by EU countries in the period 1991–2008, by employing β‐ and σ‐convergence techniques complemented by a time series analysis. Overall our results highlight a distinctive convergence pattern in the European Union. Fiscal discipline leading to a fast convergence of deficit/GDP ratio over the 1990s markedly weakened in the following decade. Nonetheless, after the Euro debut a pronounced convergence in total revenue and total government spending emerges, with different patterns characterizing each expenditure component. Despite this evidence of fiscal harmonization, European treaties failed to attract countries toward a common share of government debt over GDP. (JEL E61, H11, C23) 相似文献

This paper discusses the logical foundation and the solutions of a microfounded aggregate demand … aggregate supply model under the disequilibrium hypothesis. We first show that a) the latter hypothesis is the only one ensuring model consistent expectations and that b) price predetermination, more than price flexibility, should be embodied in an AD-AS framework. Then we develop a full AD-AS scheme, both under excess supply and excess demand for labour. We prove that in the latter case no well defined equilibrium exists. Finally, we discuss stability and perform some comparative statics exercises. 相似文献
