THE EURO AND THE GEOGRAPHY OF INTERNATIONAL DEBT FLOWS

Greater financial integration between core and peripheral European Monetary Union (EMU) members not only had an effect on both sets of countries but also spilled over beyond the euro area. Lower interest rates allowed peripheral countries to run bigger deficits, which inflated their economies by allowing credit booms. Core EMU countries took on extra foreign leverage to expose themselves to the peripherals. We present a stylized model that illustrates possible mechanisms for these developments. We then analyze the geography of international debt flows using multiple data sources and provide evidence that after the euro's introduction, core EMU countries increased their borrowing from outside of the EMU and their lending to the EMU periphery. Moreover, we present evidence that large core EMU banks' lending to periphery borrowers was linked to their borrowing from outside of the euro area.     

THE INTERNATIONAL DIMENSION OF PRODUCTIVITY AND DEMAND SHOCKS IN THE US ECONOMY

This paper analyzes the cross‐country effects of productivity and demand disturbances in the United States identified with sign restrictions based on standard theory. Productivity gains in US manufacturing increase US consumption and investment vis‐à‐vis foreign countries, resulting in a trade deficit and higher international prices of US goods, despite the rise in their supply. Financial adjustment works via a higher global value of US equities, real dollar appreciation, and an expansion of US gross foreign liabilities as well as assets. Positive demand shocks to US manufacturing also increase investment and cause a real dollar appreciation, but have limited effects on the trade balance and net foreign assets. Our findings emphasize the importance for macroeconomic interdependence of endogenous fluctuations in aggregate demand across countries in response to business cycle shocks.     

THE DEMAND FOR LIQUID ASSETS,CORPORATE SAVING,AND INTERNATIONAL CAPITAL FLOWS

The recent period of capital outflows from emerging economies has coincided with an increase in their corporate saving. In this paper, we model corporate saving as a demand for liquid assets by credit‐constrained firms in a dynamic open‐economy macroeconomic model. We find that the implications of this model are very different from standard models, because the demand for foreign bonds is a complement to domestic investment rather than a substitute. We show that this complementarity is at work when an emerging economy is on its convergence path or when it has a higher TFP growth rate. This framework is consistent with a number of stylized facts found in high‐growth, high‐investment emerging economies.     

CREDIT CONSTRAINTS AND THE CYCLICALITY OF R&D INVESTMENT: EVIDENCE FROM FRANCE

We use a French firm‐level data set containing 13,000 firms over the period 1994–2004 to analyze the relationship between credit constraints and firms’ R&D behavior over the business cycle. Our main results can be summarized as follows: (i) R&D investment is countercyclical without credit constraints, but it becomes procyclical as firms face tighter credit constraints; (ii) this result is only observed for firms in sectors that depend more heavily upon external finance, or that are characterized by a low degree of asset tangibility; (iii) in more credit‐constrained firms, R&D investment plummets during recessions but does not increase proportionally during upturns.     

DEEP FINANCIAL INTEGRATION AND VOLATILITY

We investigate the relationship between foreign direct ownership of firms and firm‐ and region‐level output volatility using a novel panel data set for European countries. We document a positive, highly robust, relationship between firm‐level foreign ownership and volatility of value added. This relationship holds cross‐sectionally and in panels with firm fixed effects where the relationship captures within‐firm variation over time. Considering domestic firms with assets in foreign countries, we document that it is international diversification, rather than the nationality of the owner, that explains this positive correlation. Our results can also be found at the aggregate level, where we show that region‐level volatility is correlated positively with foreign investment in the region. We show that this positive relation between aggregate volatility and foreign investment can be explained by the granularity of the firm size distribution and the fact that foreign ownership is concentrated among the largest firms.     

PRICE‐LEVEL CHANGES AND THE REDISTRIBUTION OF NOMINAL WEALTH ACROSS THE EURO AREA

We show that unexpected price‐level movements generate sizable wealth redistribution in the Euro Area (EA), using sectoral accounts and newly available data from the Household Finance and Consumption Survey. The EA as a whole is a net loser of unexpected price‐level decreases, with Italy, Greece, Portugal, and Spain losing most in per capita terms, and Belgium and Malta being net winners. Governments are net losers of deflation, while the household (HH) sector is a net winner in the EA as a whole. HHs in Belgium, Ireland, Malta, and Germany experience the biggest per capita gains, while HHs in Finland and Spain turn out to be net losers. Considerable heterogeneity exists also within the HH sector: relatively young middle class HHs are net losers of deflation, while older and richer HHs are winners. As a result, wealth inequality in the EA increases with unexpected deflation, although in some countries (Austria, Germany, and Malta) inequality decreases due to the presence of relatively few young borrowing HHs. We document that HHs' inflation exposure varies systematically across countries, with HHs in high‐inflation EA countries holding systematically lower nominal exposures.     

REPATRIATION OF DEBT IN THE EURO CRISIS

With the beginning of the Euro Crisis, the long‐standing trend of European financial integration reversed. Investors unwound cross‐border positions of debt obligations and increased holdings of locally issued debt. In other words, debt obligations were repatriated. We use data on bank portfolios to document three new empirical regularities of the financial disintegration: (i) repatriation affected mainly debt of crisis countries; (ii) repatriation affected mainly public debt; (iii) the public debt of crisis countries that was not repatriated was reallocated to large and politically influential countries within the Euro area. We read these results in light of standard theories of cross‐border portfolio allocation and argue that the sum of these patterns constitutes evidence for the secondary market theory of public debt.     

THE INTERNATIONAL TRANSMISSION OF VOLATILITY SHOCKS: AN EMPIRICAL ANALYSIS

This paper proposes an empirical model which can be used to estimate the international transmission of volatility shocks. Using this model we estimate that a one standard deviation increase in the volatility of the shock to US real GDP leads to a decline in UK GDP of 1% relative to trend and a 0.7% increase in UK CPI relative to trend at the two‐year horizon. Using a nonlinear open‐economy DSGE model, we find that these empirical estimates are consistent with the response to a perturbation to the volatility of foreign “supply” type shocks, while an increase in the volatility of demand shocks has a negligible impact.     

OIL AND THE MACROECONOMY: A QUANTITATIVE STRUCTURAL ANALYSIS

We model an open economy where macroeconomic variables fluctuate in response to oil supply shocks, as well as aggregate demand and supply shocks generated domestically and abroad. We use several robust predictions of the model to identify five fundamental shocks underlying the fluctuations of the (real) oil price, the US activity and the global business cycle. The estimates show that supply shocks generated in the global economy explain the largest fraction of the oil price fluctuations, about four times more than canonical oil supply shocks. The correlation between oil prices and the US activity varies with the type of shock.     

WHY DO EMERGING ECONOMIES BORROW SHORT TERM?

We argue that one reason why emerging economies borrow short term is that it is cheaper than borrowing long term. This is especially the case during crises, as during these episodes the relative cost of long‐term borrowing increases. We construct a unique database of sovereign bond prices, returns, and issuances at different maturities for 11 emerging economies from 1990 to 2009 and present a set of new stylized facts. On average, these countries pay a higher risk premium on long‐term than on short‐term bonds. During crises, the difference between the two risk premia increases and issuance shifts towards shorter maturities. To illustrate our argument, we present a simple model in which the maturity structure is the outcome of a risk‐sharing problem between an emerging economy subject to rollover crises and risk‐averse international investors.     

SOVEREIGNS,UPSTREAM CAPITAL FLOWS,AND GLOBAL IMBALANCES

We construct measures of net private and public capital flows for a large cross‐section of developing countries considering both creditor and debtor side of the international debt transactions. Using these measures, we demonstrate that sovereign‐to‐sovereign transactions account for upstream capital flows and global imbalances. Specifically, we find that (i) international net private capital flows (inflows minus outflows of private capital) are positively correlated with countries' productivity growth, (ii) net sovereign debt flows (government borrowing minus reserves) are negatively correlated with growth only if net public debt is financed by another sovereign, (iii) net public debt financed by private creditors is positively correlated with growth, (iv) public savings are strongly positively correlated with growth, whereas correlation between private savings and growth is flat and statistically insignificant. These empirical facts contradict the conventional wisdom and constitute a challenge for the existing theories on upstream capital flows and global imbalances.     

QUALITY LADDERS IN A RICARDIAN MODEL OF TRADE WITH NONHOMOTHETIC PREFERENCES

The North–South trade literature has traditionally explored conditions under which international trade might further magnify income disparities between the advanced North and the backward South. We show that even when no single country is initially more advanced than any other one and productivity changes are uniform and identical in all countries, trade may still be a source of income divergence when nonhomothetic preferences and quality ladders are jointly taken into account. Income divergence will be experienced when comparative advantages induce patterns of specialization that, although initially optimal for all countries, do not offer the same scope for quality upgrading of final products.     

RAILROADS AND GROWTH IN PRUSSIA

We study the effect of railroad access on urban population growth. Using GIS techniques, we match triennial population data for roughly 1,000 cities in 19th‐century Prussia to georeferenced maps of the German railroad network. We find positive short‐ and long‐term effects of having a station on urban growth for different periods during 1840–1871. Causal effects of (potentially endogenous) railroad access on city growth are identified using propensity score matching, instrumental variables, and fixed‐effects estimation techniques. Our instrument identifies exogenous variation in railroad access by constructing straight‐line corridors between nodes. Counterfactual models using pre‐railroad growth yield no evidence to support the hypothesis that railroads appeared as a consequence of a previous growth spurt.     

COUNTRY PORTFOLIOS IN OPEN ECONOMY MACRO‐MODELS

This paper develops a simple approximation method for computing equilibrium portfolios in dynamic general equilibrium open economy macro‐models. The method is widely applicable, simple to implement, and gives analytical solutions for equilibrium portfolio positions in any combination or types of asset. It can be used in models with any number of assets, whether markets are complete or incomplete, and can be applied to stochastic dynamic general equilibrium models of any dimension, so long as the model is amenable to a solution using standard approximation methods. We first illustrate the approach using a simple two‐asset endowment economy model, and then show how the results extend to the case of any number of assets and general economic structure.     

FRAGILE STATES AND DEVELOPMENT POLICY

It is widely recognized that fragile states are key symptoms of under‐development in many parts of the world. Such states are incapable of delivering basic services to their citizens and political violence is commonplace. As of yet, mainstream development economics has not dealt in any systematic way with such concerns and the implications for development assistance. This paper puts forward a framework for analyzing fragile states and applies it to a variety development policies in different types of states.     

INFLATION RISK PREMIA IN THE TERM STRUCTURE OF INTEREST RATES

This paper estimates the size and dynamics of inflation risk premia in the euro area, based on a joint model of macroeconomic and term structure dynamics. Information from both nominal and index‐linked yields is used in the empirical analysis. Our results indicate that the inflation risk premium on euro area 10‐year nominal yields was approximately equal to 20 basis points on average over the 1999–2007 period. The inflation premium has also been subject to moderate, but statistically significant fluctuations. For the post‐2003 period in which reliable index‐linked bond prices are available, our results suggest that increases in the raw break‐even inflation rate above 2%, the upper bound of the European Central Bank's definition for price stability, have mostly reflected variations in the inflation risk premium, while long‐term inflation expectations have remained well anchored.     

WHY AGNOSTIC SIGN RESTRICTIONS ARE NOT ENOUGH: UNDERSTANDING THE DYNAMICS OF OIL MARKET VAR MODELS

Sign restrictions on the responses generated by structural vector autoregressive models have been proposed as an alternative approach to the use of exclusion restrictions on the impact multiplier matrix. In recent years such models have been increasingly used to identify demand and supply shocks in the market for crude oil. We demonstrate that sign restrictions alone are insufficient to infer the responses of the real price of oil to such shocks. Moreover, the conventional assumption that all admissible models are equally likely is routinely violated in oil market models, calling into question the use of posterior median responses to characterize the responses to structural shocks. When combining sign restrictions with additional empirically plausible bounds on the magnitude of the short‐run oil supply elasticity and on the impact response of real activity, however, it is possible to reduce the set of admissible model solutions to a small number of qualitatively similar estimates. The resulting model estimates are broadly consistent with earlier results regarding the relative importance of demand and supply shocks for the real price of oil based on structural vector autoregressive (VAR) models identified by exclusion restrictions, but imply very different dynamics from the posterior median responses in VAR models based on sign restrictions only.     

POLITICAL SELECTION IN CHINA: THE COMPLEMENTARY ROLES OF CONNECTIONS AND PERFORMANCE

Who becomes a top politician in China? We focus on provincial leaders—a pool of candidates for top political office—and examine how their chances of promotion depend on their performance in office and connections with top politicians. Our empirical analysis, based on the curriculum vitae of Chinese politicians, shows that connections and performance are complements in the Chinese political selection process. This complementarity is stronger the younger provincial leaders are relative to their connected top leaders. To provide one plausible interpretation of these empirical findings, we propose a simple theory in which the complementarity arises because connections foster loyalty of junior officials to senior ones, thereby allowing incumbent top politicians to select competent provincial leaders without risking being ousted. Our findings shed some light on why a political system known for patronage can still select competent leaders.     

CROSS‐COUNTRY VARIATION IN THE IMPACT OF INTERNATIONAL MIGRATION: CANADA,MEXICO, AND THE UNITED STATES

Using data drawn from the Canadian, Mexican, and U.S. censuses, we find a numerically comparable and statistically significant inverse relation between immigrant‐induced shifts in labor supply and wages in each of the three countries: A 10% labor supply shift is associated with a 3%–4% opposite‐signed change in wages. Despite the similarity in the wage response, the impact of migration on the wage structure differs significantly across countries. International migration narrowed wage inequality in Canada; increased it in the United States; and reduced the relative wage of workers at the bottom of the skill distribution in Mexico.

UNEMPLOYMENT INSURANCE IN WELFARE STATES: THE IMPACTS OF SOFT DURATION CONSTRAINTS

Abstract Based on a major reform of Norwegian unemployment insurance (UI), we examine the behavioral impacts of soft and hard UI duration constraints. A constraint is interpreted as hard if a claimant cannot rely on any form of income support after exhaustion, and as soft if UI is replaced by follow‐on benefits or participation in active labor market programs (ALMP). We find that both hard and soft constraints raise the job hazard significantly, with surprisingly similar spikes at UI exhaustion. Participation in ALMP raises the probability of eventually finding a job, but at the cost of lengthening the overall job‐search period.
