Bank Asset Quality in Emerging Markets: Determinants and Spillovers

This paper assesses the vulnerability of emerging markets and their banks to aggregate shocks. We find significant links between banks’ asset quality, credit and macroeconomic aggregates. Lower economic growth, an exchange rate depreciation, weaker terms of trade and a fall in debt-creating capital inflows reduce credit growth while loan quality deteriorates. Particularly noteworthy is the sharp deterioration of balance sheets following a reversal of portfolio inflows. We also find evidence of feedback effects from the financial sector on the wider economy. GDP growth falls after shocks that drive non-performing loans higher or generate a contraction in credit. This analysis was used in chapter 1 of the Global Financial Stability Report (September 2011) to help evaluate the sensitivity of banks’ capital adequacy ratios to macroeconomic and funding cost shocks.

Investment-Specific Technology Shocks and Labor Market Frictions

This paper studies the implications of technical progress through investment-specific technical change in a business cycle model with search and matching frictions and endogenous job destruction. The interaction between the capital formation needed to reap the benefits of an investment-specific technology shock and gradual labor-market matching, generates hump-shaped, persistent responses in output, vacancies, and unemployment. The endogenous job destruction decision also leads to small but persistent endogenous fluctuations in total factor productivity. Simulations suggest a limited role for investment-specific technology shocks as a source of business cycle fluctuations compared to a standard real business cycle model.

Aggregate shocks and labor market fluctuations

This paper evaluates the dynamic response of worker flows, job flows, and vacancies to aggregate shocks in a structural vector autoregression. We identify demand, monetary, and technology shocks by imposing sign restrictions on the responses of output, inflation, the interest rate, and the relative price of investment. No restrictions are placed on the responses of job and worker flows variables. We find that both investment-specific and neutral technology shocks generate responses to job and worker flows variables that are qualitatively similar to those induced by monetary and demand shocks. However, technology shocks have more persistent effects. The job finding rate largely drives the response of unemployment, though the separation rate explains up to one third. For job flows, the destruction margin is more important than the creation margin in driving employment growth. Measuring reallocation from job flows, we find that monetary and demand shocks do not have significant effects on cumulative job reallocation, whereas expansionary technology shocks have mildly negative effects. We also estimate shock-specific matching functions. Allowing for a break in 1984:Q1 shows considerable subsample differences in matching elasticities and relative shock-specific efficiency.

Supply Shocks, Demand Shocks, and Labor Market Fluctuations

We use structural vector autoregressions to analyze the responses of worker flows, job flows, vacancies, and hours to shocks. We identify demand and supply shocks by restricting the short-run responses of output and the price level. On the demand side we disentangle a monetary and non-monetary shock by restricting the response of the interest rate. The responses of labor market variables are similar across shocks: expansionary shocks increase job creation, the hiring rate, vacancies, and hours. They decrease job destruction and the separation rate. Supply shocks have more persistent effects than demand shocks. Demand and supply shocks are equally important in driving business cycle fluctuations of labor market variables. Our findings for demand shocks are robust to alternative identification schemes involving the response of labor productivity at different horizons and an alternative specification of the VAR. However, supply shocks identified by restricting productivity generate a higher fraction of responses inconsistent with standard search and matching models.

Will Natural Gas Prices Decouple from Oil Prices Across the Pond

We show that US natural gas prices have decoupled from oil prices following substantial institutional and technological changes. We then examine how this interrelationship has evolved in Europe using data for Algeria, one of Europe’s key gas suppliers. Taking into account total gas exports and cyclical conditions in partner countries, we find that gas prices remain linked to oil prices, though the nexus has loosened. Both high oil prices and a modest industrial recovery in partner countries have kept gas exports at low levels in recent years, suggesting changing market forces. The paper then shows how such shifts can have important macroeconomic implications for a big gas exporter such as Algeria.

The Composition and Cyclical Behavior of Trade Flows in Emerging Economies

The composition and cyclical properties of imports are similar in developed economies and emerging economies (EM) but this is not the case for exports. Unlike developed economies, (i) EM export few or only a selective set of capital goods and (ii) capital good and overall exports tend to be acyclical. The lack of procyclicality in exports helps to explain the strong countercyclicality of EM trade balances observed in previous studies. A quantitative exercise demonstrates how the standard small open economy business cycle model could be improved upon by incorporating some of these features.

Spillovers From Europe Into Morocco and Tunisia

This paper examines the economic and financial linkages between Morocco and Tunisia and their European partners. Using structural vector autoregressions, we find that growth shocks in European partner countries generate significant responses on growth in Morocco and Tunisia. For Tunisia, exports and, to a much lesser extent, tourism appear to be the major transmission channels. In Morocco, exports, remittances and tourism play relatively equal roles. An analysis with sectoral data supports these results.

The Cost of Volatile Investment in an Emerging Economy

I measure the welfare gains from eliminating fluctuations in investment in an emerging economy such as Argentina. The estimated welfare effects are an order of magnitude higher than those for the US and arise with moderate degrees of diminishing returns to investment.

What Happens in Emerging Markets If Recent Bank and Portfolio Inflows Reverse

A substantial amount of foreign portfolio and bank-related capital has been flowing into a number of emerging market economies since 2009. A reversal of these flows as a consequence of financial deleveraging or waning risk appetite could place the financial sectors of many of those economies under substantial pressure. Research indicates that if these flows were to reverse, growth prospects would deteriorate and currencies would weaken vis-à-vis the U.S. dollar. Bank lending to the private sector would contract significantly, and the asset quality of banks’ balance sheets would deteriorate.
