The article adds to the micro-foundations of the PTI, framing more rigorously the role of global investors as international allocators of capital resources, and providing richer analysis of their interaction with macroeconomic policies at country level. The article explores how country credibility enters the capital allocation choice process of global investors and how global investor choices shape the space available to country policy making, determining the extent to which the effect of macro-policies dissipates into exchange rate depreciation and higher inflation. |\n|  |  |\n\nURL: [http://mc.manuscriptcentral.com/reme](http://mc.manuscriptcentral.com/reme) [Email: mfeme@igidr.ac.in](Email: mfeme@igidr.ac.in)  \nPage 1 of 38 Macroeconomics and Finance in Emerging Market Economies  \n1 2  \n3 4  \n5 6  \n7 8  \n9  \n10  \n11  \n12  \n13  \n14  \n15  \n16  \n17  \n18  \n19  \n20  \n21  \n22  \n23  \n24  \n25  \n26  \n27  \n28  \n29  \n30  \n31  \n32  \n33  \n34  \n35  \n36  \n37  \n38  \n39  \n40  \n41  \n42  \n43  \n44  \n45  \n46  \n47  \n48  \n49  \n50  \n51  \n52  \n53  \n54  \n55  \n56  \n57  \n58  \n59  \n60  \nTHE PORTFOLIO THEORY OF INFLATION AND POLICY (IN)EFFECTIVENESS: A  \nREVISITATION  \n1. INTRODUCTION1  \nThe forces of globalization demand that each country considers realistically how effective its macropolicies can be, given its own characteristics and circumstances. In my recent work on the Portfolio Theory of Inflation (PTI),2 I have analyzed how financial globalization affects the policy space available to authorities at country level – in many cases constraining it to the point of rendering expansionary macro-policies ineffective or even ~~outright~~ destabilizing.3  \nThe issue – one that is especially (though not exclusively) important~~)~~ for developing and emerging market economies – is that despite financial globalization, current macroeconomic policy modelling continues to rely on domestic representative agents and fails to recognize the role~~ global~~  \n1 I am hugely ~~wis~~grateful ~~h~~~~to~~~~thank~~to the anonymous referee of this journal for the very helpful comments and suggestions provided to me across the various draft revisions.
