We compare two ways of modeling Calvo-type wage stickiness. One in which each household is the monopolistic supplier of a differentiated type of labor input (as in Erceg, et al., 2000) and one in which households supply a homogenous labor input that is transformed by monopolistically competitive labor unions into a differentiated labor input (as in Schmitt-Grohé and Uribe, 2006a,b). We show tha...

This study examines the convergence patterns of Euro Area (EA) 17 countries’ sovereign bond yield spreads (relative to German bund) over the period of March 2002 to December 2015, by employing the convergence algorithm developed by Phillips and Sul (2007). The empirical findings suggest rejection of full convergence across the EA17 countries’ bond yields spreads, and the presence of a certain n...

the major challenge facing iranian economy is its overwhelming dependence on the oil exports. however, the world oil price has been subject to a lot of shocks, which have destabilized the iranian terms of trade. hence, this paper empirically examines the effect of terms of trade volatility on iran’s economic growth over 1967-2006. for this purpose, based on a garch model, a proxy for the terms ...

The tendency of countries to accumulate public debt has been rationalized in models of political disagreement and lack of commitment. We analyze in a benchmark model how the evolution of public debt is affected by lack of commitment per se. While commitment introduces indeterminacy in the level of debt, lack of commitment creates incentives for debt to converge to specific levels. One of the le...

This paper develops a model of the circumstances under which it is beneficial to participate in a currency area. The proposed two-country monetary model of trade with nominal rigidities encompasses the real and monetary arguments suggested by the optimum currency area literature: correlation of real and monetary shocks, international factor mobility, fiscal adjustment, openness, difference in n...

The paper shows that common fiscal rules, such as a limit to the deficit-output ratio, induce an ‘‘escape clause’’–type fiscal policy, similar to that studied for monetary policy by Flood and Isard (1988 and 1989) and Lohmann (1992): The government resorts to an active stabilization (for example, countercyclical) policy only during ‘‘exceptional times’’ by running deficits in recession phases a...

This paper explains a currency crisis as an outcome of a switch in how monetary policy and fiscal policy are coordinated. The paper develops a model of an open economy in which monetary policy starts active, fiscal policy starts passive and, in a particular state of nature, monetary policy switches to passive and fiscal policy switches to active. The probability of the regime switch is endogeno...

Many governments around the world are considering measures of happiness or subjective wellbeing as alternatives to gross domestic product (GDP) for the purpose of guiding economic policymaking. Compared to GDP, happiness measures promise to better capture the quality of life of a nation’s citizens and lead to policies that are more effective and equitable. However, there are a number of problem...
