Owing to dissatisfaction with the IMF’s de jure classification of exchange-rate regimes, a substantial literature has emerged presenting de facto classifications of exchange-rate systems and using the latter classifications to compare performances of alternative regimes in terms of key...

We compare monetary union to flexible exchange rates in an asymmetric, three country model with active monetary policy. Unlike the traditional OCA literature, we find that countries with a high degree of nominal wage rigidity benefit from monetary union, specially when they join other, similarly...

We examine the implications of a regional, fixed exchange rate regime for global exchange rate volatility. The concept of the optimum currency area turns out to play an important role. The formation of a regional regime tends to decrease global volatility when countries are symmetric. The...

Macroeconomic models that omit the shadow economy systematically mis-forecast and mis-measure the effect of fiscal –in particular tax– policy on economic activity and tax revenue. We add an informal sector to the Bank of Greece DSGE model and use the actual package of fiscal consolidation...

Fiscal fragility can undermine a government’s ability to honor its bank deposit insurance pledge and induces a positive correlation between sovereign default risk and financial (bank) default risk. We show that this positive relation is reversed if bank capital requirements in fiscally weak...

We study the role of the loan-to-value (LTV) ratio instrument in a DSGE model with a rich set of financial frictions (Clerc et al., 2015). We find that a binding LTV ratio limit in the mortgage market leads to lower credit and default rates in that market as well as lower levels of investment...

We provide a new way of deriving a number of dynamic unobserved factors from a set of variables. We show how standard principal components may be expressed in state space form and estimated using the Kalman filter. To illustrate our procedure we perform two exercises. First, we use it to...

During the late-1940s and the early-1950s Milton Friedman favored a rule under which fiscal policy would be used to generate changes in the money supply with the aim of stabilizing output at full employment. He believed that the economy is inherently unstable because of endogenous movements in...

Trade is spatial in nature. However, when specifying trade regressions, spatial issues are typically not accounted for in a satisfactory way. We specify a trade model which relates to the effects that the introduction of the euro had on exports for the euro countries. Our model contains country...

A recent contribution to the literature argues that the present international monetary system in many ways operates like the Bretton-Woods system. Asia is the new periphery of the system and pursues an export-led development strategy based on undervalued exchange rates and accumulated foreign...
