International business cycles with domestic and foreign lenders

We examine the international transmission of business cycles in a two-country model where credit contracts are imperfectly enforceable. In our economy, foreign lenders differ from domestic lenders in their ability to recover value from borrowers’ assets and, therefore, to protect themselves against contractual non-enforceability. The relative importance of domestic and foreign credit frictions changes over the cycle. This induces entrepreneurs to adjust their debt exposure and allocation of collateral between domestic and foreign lenders in response to exogenous productivity shocks. We show that such a model can explain the comovement of output across countries.     

A comprehensive approach to measuring the relation between systemic risk exposure and sovereign debt

Using an integrated model to control for simultaneity, as well as new risk measurement techniques such as Adapted Exposure CoVaR and Marginal Expected Shortfall (MES), we show that the aggregate systemic risk exposure of financial institutions is positively related to sovereign debt yields in European countries in an episodic manner, varying positively with the intensity of the financial crisis facing a particular nation. We find evidence of a simultaneous relation between systemic risk exposure and sovereign debt yields. This suggests that models of sovereign debt yields should also include the systemic risk of a country's financial system in order to avoid potentially important mis-specification errors. We find evidence that systemic risk of a country's financial institutions and the risk of sovereign governments are inter-related and shocks to these domestic linkages are stronger and longer lasting than international risk spillovers. Thus, the channel in which domestic sovereign debt yields can be affected by another nation's sovereign debt is mostly an indirect one in that shocks to a foreign country's government finances are transmitted to that country's financial system which, in turn, can spill over to the domestic financial system and, ultimately, have a destabilizing effect on the domestic sovereign debt market.     

Financial friction in an emerging economy

The objective of this study is to evaluate the role of the frictional domestic credit market in an emerging country by using a small-open-economy DSGE model with a banking sector. The calibration results show that the financial friction does not significantly influence the macroeconomic effects of the shocks to the domestic productivity, foreign interest rate and export demand. We also evaluate whether and how the trade and financial openness can influence the effects of the domestic financial shocks that in turn affect the supply of loans in the credit market. We show that greater trade and financial openness can reduce the macroeconomic impacts of the domestic financial distress. Under a more open international capital market, the capital outflow caused by the domestic financial shock does not lead to drastic exchange rate variation. This helps dampen the adverse effects of the financial distress on the economy.     

Capital structure and international debt shifting

This paper presents a model of a multinational firm's optimal debt policy that incorporates international taxation factors. The model yields the prediction that a multinational firm's indebtedness in a country depends on a weighted average of national tax rates and differences between national and foreign tax rates. These differences matter as multinationals have an incentive to shift debt to high-tax countries. The predictions of the model are tested using a novel firm-level dataset for European multinationals and their subsidiaries, combined with newly collected data on the international tax treatment of dividend and interest streams. Our empirical results show that a foreign subsidiary's capital structure reflects local corporate tax rates as well as tax rate differences vis-à-vis the parent firm and other foreign subsidiaries, although the overall economic effect of taxes on leverage appears to be small. Ignoring the international debt shifting arising from differences in national tax rates would understate the impact of national taxes on debt policies by about 25%.     

Capital flows,investment, and exchange rates

This paper incorporates international capital flows into a two-country, monetary-general-equilibrium model of asset prices with investment and production. We calculate theoretical covariances between investment, the current account, the exchange rate, and the terms of trade. These covariances depend upon the coefficient of relative risk aversion, the magnitude and sign of a country's net international indebtedness, other properties of tastes and technologies, and the stochastic processes on disturbances to productivity and monetary growth rates. International capital flows arise from changes in world wealth and its relative composition in foreign and domestic assets.     

贸易摩擦、宏观经济波动与经济开放程度的选择

本文构建一个包含关税冲击以及外汇风险溢价的两国开放经济DSGE模型,创新地揭示了关税冲击造成实际汇率波动的“直接效应”与“间接效应”,刻画了关税变动、贸易条件与实际汇率之间的动态关系与作用机制。我们深入分析了不同经济开放程度下贸易摩擦造成的宏观经济波动以及经济福利损失。模拟结果表明,在一定贸易开放程度下,外国加收关税一方面会导致本国贸易条件恶化,引发出口及产出下降;另一方面会导致本国汇率贬值,引发出口及产出增长。关税冲击发生后短期中汇率贬值效应占优,本国产出会出现小幅上升,随后贸易条件恶化效应逐步显现,产出持续下降。福利分析结果表明,本国适度提升贸易开放度,虽然经济福利损失会小幅上升,但福利损失增加幅度小于外国,会在贸易摩擦竞争中形成相对优势;如果本国过度提高贸易开放度,则会导致本国福利损失大幅增加,并且大于外国福利损失增幅,会在贸易摩擦竞争中形成相对劣势。因此,应适度逐步有序地提升贸易开放度。此外,本国适度推进资本账户开放的政策能够改善贸易条件,促进本国经济增长。

Financial Exposure and the International Transmission of Financial Shocks

This paper analyzes the transmission mechanism of banking sector shocks in an international real business cycle model with heterogeneous bank sizes. We examine to what extent the financial exposure of the banking sector affects the transmission of foreign banking sector shocks. In our model, the more exposed domestic banks are to the foreign economy via lending to foreign firms, the greater are the spillovers from foreign financial shocks to the home economy. The model highlights the role of openness to trade and the dynamics of the terms of trade in the international transmission mechanism of banking sector shocks: spillovers from foreign banking sector shocks are greater the more open the home economy is to trade and the less the terms of trade respond to foreign shocks.     

Sovereign debt and reserves with liquidity and productivity crises

During the recent financial crisis, emerging economies have kept accumulating both sovereign reserves and debt. To account for this empirical fact, we model the optimal portfolio choice of a sovereign that is subject to liquidity and productivity shocks. We determine the equilibrium level of debt and its cost by solving a contracting game between sovereign and international lenders. Although raising debt increases the sovereign exposure to liquidity and productivity crises, the simultaneous accumulation of reserves can mitigate the negative effects of such crises. This mechanism rationalizes the complementarity between debt and reserves.     

International spillovers from Euro area and US credit and demand shocks: A focus on emerging Europe

In this paper, we examine the international effects of contractions in loan supply, loan demand and aggregate demand in the euro area and the USA. All three shocks have been at the forefront in spreading stress during the period of the global financial crisis and in particular so to countries that are strongly integrated with the euro area. We find that these shocks decrease international output and total credit to a varying degree. Loan demand and aggregate demand shocks in the euro area trigger significant negative spillovers on output in most other regions. Evidence for global negative output effects of euro area loan supply shocks is fraught with considerable estimation uncertainty. When these three types of shocks emanate from the USA, we find significant negative spillovers on output also for loan supply shocks. In general, international effects on total credit are an order of magnitude larger than those on output, with again more evidence that is significant for US than euro area shocks. Last, and taking a regional stance, our results indicate that economies from emerging Europe are most vulnerable to all shocks considered. Through their strong economic integration with the euro area, these economies are likewise exposed to euro area and US shocks, and spillover effects are often larger than the domestic response in the country of shock-origin.     

International income risk-sharing and the global financial crisis of 2008–2009

We examine the impact of the global financial crisis on the degree of international income and consumption risk-sharing among industrial economies using returns on cross-border portfolio holdings (e.g., debt, equity, FDI). We split the returns from the net foreign holdings as receipts (inflows) and payments (outflows) to investigate which of the two sides exhibited the greater resilience for income risk-sharing during the recent crisis. First, we find that debt delivered better risk-sharing than equity, mainly reflecting the deficit deterioration in EMU countries during the post-crisis period. FDI, by contrast, did not correspond to noticeable risk diversification. Second, separating output shocks into positive and negative components reveals that debt holding receipts (equity liability payments) performed better under negative (positive) realizations of the shock variable. Third, the unwinding of capital flows resulted in a sharp fall in income dis-smoothing via the debt liability channel in the new EU countries.     

The shortage of safe assets in the US investment portfolio: Some international evidence

This paper develops a Bayesian Global VAR (GVAR) model to track the international transmission dynamics of two stylized shocks, namely a supply and demand shock to US-based safe assets. Our main findings can be summarized as follows. First, we find that (positive) supply-sided shocks lead to pronounced increases in economic activity which spills over to foreign countries. The impact of supply-sided shocks can also be seen for other quantities of interest, most notably equity prices and exchange rates in Europe. Second, a demand-sided shock leads to an appreciation of the US dollar and generally lower yields on US securities, forcing investors to shift their portfolios towards foreign fixed income securities. This yields sizable positive effects on US output, equity prices and a general decrease in financial market volatility.     

Household Debt Overhang and Transmission of Monetary Policy

We investigate how the level of household indebtedness affects the monetary transmission mechanism in the U.S. economy. Using state‐dependent local projection methods, we find that the effects of monetary policy are less powerful during periods of high household debt. In particular, the impact of monetary policy shocks is smaller on GDP, consumption, residential investment, house prices, and household debt during a high‐debt state. We then build a partial equilibrium model of borrower households with financial constraints to rationalize these facts. The model points to the weakening of the home equity loan channel as a possible reason for the decline in monetary policy effectiveness when initial debt levels are high.     

United States current account deficits: A stochastic optimal control analysis

The “Pessimists” and the “Optimists” disagree whether the US external deficits and the associated buildup of US net foreign liabilities are problems that require urgent attention. A warning signal should be that the debt ratio deviates significantly from the optimal ratio. The optimal debt ratio or debt burden should take into account the vulnerability of consumption to shocks from the productivity of capital, the interest rate and exchange rate. The optimal debt ratio is derived from inter-temporal optimization using Dynamic Programming, because the shocks are unpredictable, and it is essential to have a feedback control mechanism. The optimal ratio depends upon the risk adjusted net return and risk aversion both at home and abroad. On the basis of alternative estimates, we conclude that the Pessimists’ fears are justified on the basis of trends. The trend of the actual debt ratio is higher than that of the optimal ratio. The Optimists are correct that the current debt ratio is not a menace, because the current level of the debt ratio is not above the corresponding level of the optimum ratio.     

Sovereign Defaults,Credit to the Private Sector,and Domestic Credit Market Institutions

Sovereign defaults are associated with declines in foreign and domestic credit to the domestic private sector. This paper analyzes theoretically whether sovereign defaults can lead to this decline, even if domestic agents do not hold sovereign debt. It also studies whether the quality of domestic financial institutions affect the magnitude of this effect. In order to address these issues, the paper embeds the traditional sovereign borrower/foreign creditors relationship of the sovereign debt literature in a macromodel where widespread individual financial constraints limit a country's ability to reallocate resources. The paper finds that sovereign defaults can indeed generate a decline in foreign and domestic credit even if domestic agents do not hold sovereign debt, and that stronger domestic financial institutions can amplify this effect. These findings constitute a new step toward understanding the costs of sovereign defaults.     

中国货币政策目标制的选择——基于开放经济体的实证

本文使用开放经济下的新凯恩斯模型实证分析了开放经济体中不同的货币政策目标制。结果表明,面对国内利率政策、技术、国外通货膨胀、国外产出和国外实际利率冲击时,由灵活通货膨胀目标、资本自由流动和完全浮动的汇率构成的货币政策目标体系能够有效吸收冲击,减缓经济波动。相比而言,严格通胀目标制无法有效吸收国内外冲击,所以我国在开放经济下选择货币政策目标时,并不一定要选择严格通货膨胀目标,可以选择一些灵活通货膨胀目标的政策框架。此外,能够有效吸收各种冲击的灵活通胀目标、资本自由流动和完全浮动汇率制组成的目标体系也为我国货币政策和汇率制度改革提供了方向。     

Following the leader? The relevance of the Fed funds rate for inflation targeting countries

In a New-Keynesian model for a small open economy, we derive a CPI inflation-based Taylor rule that implements the flexible price allocation. We conclude that, in this rule, the natural rate of interest should be linked to the foreign interest rate and to domestic productivity shocks. This rule ensures that the CPI real rate moves in order to induce movements in consumption that are coherent with the flexible price allocation. The empirical evidence shows that inflation-targeting central banks respond to movements in the Fed funds rate, besides reacting to expected CPI inflation and to the domestic output gap. This is true for developed and emerging economies. Furthermore, we find that in emerging countries the response to foreign variables is not different from zero, as suggested by theory, when domestic inflation, rather than CPI inflation, is introduced in the policy rule.

Special Exchange Rates for Capital Account Transactions

The governments of developing countries are constrained in theeffective implementation of domestic policy by the interlinkagesof national and international financial markets. Domestic macroeconomicconditions are influenced by the interaction of national andworld interest rates and prices, and through the impact of realexchange rates on employment. The domestic responses to changesin these factors are often strong and rapid. In an attempt tosever these ties, governments have adopted dual exchange ratesystems in which capital account transactions are conductedat a depreciated exchange rate while an otherwise overvaluedrate is maintained for commercial trade. This article suggeststhat dual rates can indeed be used successfully as a strictlytransitory policy to offset sudden shocks in capital markets.The article develops models which indicate why these dual systemsare able to prevent inflationary or recessionary pressures causedby a misaligned exchange rate in the short term. While freecapital account rates can cut the flow of capital flight, however,a dual rate system cannot prevent a possibly equivalent lossof foreign reserves that will ultimately result because of theimpact of the overvaluation of the commercial rate on the tradebalance. In the longer term, a dual rate system with a misalignedcommercial rate exacerbates the government's deficit; ultimately,real wages must be cut and real interest rates raised to generatesufficient foreign exchange to finance the external debt. Thusa dual rate works well if the commercial rate is maintainedclose to the equilibrium level.     

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.
