Some Background

• For any open economy, net foreign asset position (NFA) is akey variable: It limits present value of future current accountdeficits.

• Net external asset position represents a country’s solvencyconstraint.

• Traditional view: ∆NFAt = CAt.

• But: Foreign assets and liabilities are measured at marketvalue.

• Market value variations occur due to changes in asset prices,asset returns, or exchange rate changes → ”Valuationeffects”.

Page 3: Marcel PhD Conference 2012

Background Research Question Theoretical considerations Empirical model and data Estimation and results Conclusion

• Valuation effects are an important driver of NFA (Lane andMilesi-Ferreti, 2007; Gourinchas, 2007; Obstfeld, 2004):

∆NFAt = CAt + V ALt. (1)

• However, capital transfers (CAP) and unrecorded capitalflows/trade flows are also important:

∆NFAt = CAt + V ALt + CAPt + EOMt. (2)

• Can compute V ALt indirectly using Eq. 2.

• Magnitude of VAL is proportional to gross asset positions.

• Proliferation in asset trade (financial globalization) has led toa significant increase in the size of valuation adjustments.

Research Question

• How does the rising importance of VEs affect economicperformance?

• Empirically, this remains an open question.

• The purpose of the study is to fill this gap.

• Here, focus on welfare through consumption volatility.

• Currently, other channels not well understood theoretically.

Page 8: Marcel PhD Conference 2012

Background Research Question Theoretical considerations Empirical model and data Estimation and results Conclusion

Theoretical considerations

• Theoretical link between VEs and consumption is notclear-cut.

• Interpretation 1: Higher valuation-effect volatility causesgreater volatility in wealth ⇒ consumption should becomemore volatile as well.

• For risk averse agents this means a welfare loss stemmingfrom deviations from a smooth consumption path.

• Interpretation 2: VEs reflect flow payments of internationalrisk sharing → wealth not more volatile → no welfare costs.

Page 9: Marcel PhD Conference 2012

Background Research Question Theoretical considerations Empirical model and data Estimation and results Conclusion

What to expect?

• The relationship between consumption and valuation-effectvariability is conditional on:

• The currency decomposition of a country’s balance sheet.• And/or its ability to share risk internationally.

• Since Eichengreen & Hausmann (1999) it is well known thatmost developing countries face problem of ”original sin”.

• Kose et al (2009): Developing economies still unable to sharerisk internationally despite financial globalization.

Empirical model

LV OLCit = β0+β1 LV OLV ALit+β2 LV OLGit+β3 LV OLINFLit+u†it.

• LV OLC: Volatility of real private consumption growth per capita.

• LV OLV AL: Volatility of valuation effects.

• LV OLG: Volatility of real GDP per capita growth.

• LV OLINFL: Volatility of inflation rate.

• Volatility defined as log of rolling standard deviation using 10yr windows.

• β1 insignificant: cannot reject that VEs reflect risk sharing.

• β1 positive significant: VE-volatility welfare decreasing, rejectrisk sharing interpretation.

Data

• Unbalanced panel, 82 countries. Period: 1980-2007.

• Data Sources:• LV OLC & LV OLG: PWT 7.1.• LV OLINFL: WDI.• LV OLV AL: Compiled from: EWN II (Lane and

Milesi-Ferretti, 2007) and IMF BOP statistics.

Estimation and resultsMethod

• Step 1: Investigate unit root properties of the variables.

• Step 2: Estimate long-run relationship between variables.

• Step 3: Test for cointegration.

Page 13: Marcel PhD Conference 2012

Background Research Question Theoretical considerations Empirical model and data Estimation and results Conclusion

Estimation: Dynamic OLS (Mark and Sul, 2003)

LV OLCit = αi + θt + λi t+ β′ xit + u†it,

u†it =

m∑−m

δ′i∆xi,t+m + uit.

• xit = [LV OLV ALit, LV OLGit, LV OLINFLit]′

• Assumptions:• Homogenous cointegrating vector, [1,−β′].

• u†it independent across countries.

• Group-specific heterogeneity accounted for by:

Fixed effects, time fixed effects, heterogeneous time trends,disparate short-run dynamics.

Background Research Question Theoretical considerations Empirical model and data Estimation and results Conclusion

• PBM predicts: Impact of VE-volatility on consumptionvolatility depends on currency decomposition of external debt.

• I construct subsamples based on the foreign currency exposureof countries’ external debt.

• I consider the following measure:• Weight of debt liabilities (portfolio debt and other debt)

denominated in foreign currency.

Conclusion

• The results are consistent with a priori theoretical predictions.

• They suggest that valuation-effect volatility imposes welfarecosts on countries with a high share of their liabilitiesdenominated in foreign currency.

• Implication of the findings is that financial globalizationdecreases welfare in emerging and developing economies thatface the problem of original sin (partial equilibrium).

• These types of countries should take a cautious approach toliberalizing their capital account transactions.
