Current accounts and financial flows in the euro area

We construct a new database of bilateral financial flows among euro area countries and their major world partners and explore the role of financial links in the accumulation and then adjustment of current account imbalances in the euro area. The data show that the geography of financial flows can differ quite markedly from trade flow patterns and suggest that the nexus between surpluses in the 'core' with deficits in the periphery went along financial rather than trade interlinkages. In particular, the data document the dominant role of 'core' countries in financing the euro area periphery's current account deficits before the financial crisis, both directly and through intermediating financial flows from outside of the euro area. Most of this financing took the form of debt instruments. Following the withdrawal of private financing from 'core' countries during the crisis, the ECB-mediated funding and other official flows helped the periphery to refinance its liabilities and smoothen the external adjustment.     

Financial flows,financial crises,and global imbalances

In this lecture I document the proliferation of gross international asset and liability positions and discuss some consequences for individual countries’ external adjustment processes and for global financial stability. In light of the rapid growth of gross global financial flows and the serious risks associated with them, one might wonder about the continuing relevance of the net financial flow measured by the current account balance. I argue that global current account imbalances remain an essential target for policy scrutiny, for financial as well as macroeconomic reasons. Nonetheless, it is critically important for policymakers to monitor as well the rapidly evolving structure of global gross assets and liabilities.     

Securitized markets,international capital flows,and global welfare

We study the effect of collateralized lending and securitization on international capital flows and welfare in a two-country general equilibrium model with idiosyncratic investment risk. The low-margin country (Home) endogenously supplies more safe assets and enables more risk sharing. Upon financial integration, capital flows from Foreign (high-margin country) to Home, leading to lower interest rates and a larger global supply of safe assets. Unlike in standard models with partial equity issuance, in our model, Home can lose from financial integration due to the endogenous reduction in risk sharing and aggregate shocks can generate large gross capital flows.     

Current account balance and dollar standard: Exploring the linkages

This paper examines whether the international role of the dollar as main global reserve currency has contributed to persistent current account imbalances. To this end, we analyse how central banks' accumulation of reserve assets affects the current account balance of both reserve-accumulating and reserve-providing countries.Based on a simple portfolio balance model we show theoretically that the global demand for reserve assets by central banks may lower the current account balance of the reserve-issuing country. Our panel data analysis over the period 1970–2009 confirms this hypothesis: Any dollar of provided reserve assets decreases the US current account by more than one dollar. On average, the demand for dollar reserves has lowered the US current account by 1–2 percentage points relative to GDP. The flip side of this effect is a higher current account balance in reserve-accumulating countries. These novel findings show that the worldwide demand for international reserves has contributed to the buildup of global imbalances.     

IMF programs, financial and real sector performance, and the Asian crisis

This paper has three objectives. First, using a richer and more comprehensive set of IMF-related news than previous studies, we examine the impact of IMF-related news on both financial and real stock sector returns in Indonesia during the Asian crisis. Second, we draw lessons about financial and real sectoral patterns of adjustment in crisis countries, including whether and how IMF programs facilitate this adjustment. Third, we explore the interplay between IMF actions in crisis countries and the actions and responses of local authorities. To do so, not only do we account for the impact of news regarding IMF policy actions but also the government’s reaction to them and willingness to implement such policies, and the public sentiment about the implemented IMF programs and government policies. We discuss the policy implications of the findings.     

International portfolio flows and exchange rate volatility in emerging Asian markets

This paper investigates the effects of equity and bond portfolio inflows on exchange rate volatility using monthly bilateral data for the US vis-a-vis seven Asian developing and emerging countries (India, Indonesia, Pakistan, the Philippines, South Korea, Taiwan and Thailand) over the period 1993:01–2015:11. GARCH models and Markov switching specifications with time-varying transition probabilities are estimated in addition to a benchmark linear model. The evidence suggests that high (low) exchange rate volatility is associated with equity (bond) inflows from the Asian countries toward the US in all cases, with the exception of the Philippines. Therefore, capital controls could be an effective tool to stabilise the foreign exchange market in countries where flows affect exchange rate volatility.     

Valuation effects and long-run real exchange rate dynamics

This paper uses the Johansen test for cointegration to check the prediction of a portfolio balance model that predictable valuation effects are associated with a saddle-path dynamic relationship between the net foreign asset position and the real exchange rate. The analysis uses newly constructed quarterly series on the net foreign position as a percentage of the nominal gross domestic product, together with data on real effective exchange rate indices for a sample of developed countries which borrow in their own currency. The results indicate that the net foreign asset position and the real exchange rate are not cointegrated for all the countries in the sample. The rejection of saddle-path dynamics suggests that predictable valuation effects are quantitatively small in developed countries. The rejection of cointegration suggests that the net foreign asset position is not a determinant for long-run real exchange rates in developed countries.     

International spillovers of monetary policy: Lessons from Chile,Korea, and Poland

In this paper, we assess evidence on international monetary policy spillovers to domestic bank lending in Chile, Korea, and Poland, using confidential bank-level data and different measures of monetary policy shocks in relevant currency areas. These three emerging market economies are small and open, their banking systems do not have significant presence overseas, and they can be considered as price takers in the world economy. Such features allow for better identification of binding financial constraints and foreign monetary policy shocks. We find that the monetary policy shocks spill over into domestic bank lending, modifying the degree to which financial frictions tighten or relax, and this evidence is consistent with international bank lending and portfolio channels.     

Currency risk premia and uncovered interest parity in the International CAPM

Zero-investment uncovered interest parity (UIP) portfolio positions provide perfect factor-mimicking portfolios for currency risk in the International CAPM context. Their returns are the currency risk premia. Since the UIP positions on average provide low returns, the currency risk premia must be low so that currency risk appears not to be priced in an unconditional model. However, previous research has shown that UIP returns are predictable and may be quite substantial conditionally. We use this observation to generate a specific conditional version of the International CAPM. A GMM approach shows that the conditional model performs well, while the unconditional International CAPM is (marginally) rejected. The paper thus argues that previous rejections of the International CAPM stem from the fact that currency risk premia are by nature low over extended periods of time and do not provide evidence against the International CAPM.     

Product differentiation,market dynamics and the value relevance of trade payables: Evidence from UK listed firms

This paper provides a comprehensive evidence on how product and market dynamics affect the value relevance of trade payables. Using a sample of 2559 UK listed firms over the period 2005–2014, we find a positive relationship between trade payables and firm performance. Our evidence suggests that trade payables increase (decrease) performance in firms with differentiated products and demand uncertainty (larger market share). We demonstrate that the relative value relevance of bank credit versus suppliers’ credit is dependent on the nature of the product, the level of sales volatility, and market share. We use an innovative approach to assess the robustness of our results to omitted variable bias.
