Do recessions affect potential output

A number of previous studies have looked at the effect of financial crises on actual output several years beyond the crisis. The purpose of this paper is to examine whether the growth of potential output also is affected by recessions, whether or not they include financial crises. Trend per capita output growth is calculated using HP filters, and average growth is compared for the two years preceding a recession, the two years immediately following a recession peak, and the two years after that. Panel regressions are run to determine whether characteristics of recessions, including depth, length, extent to which they are synchronized across countries, and whether or not they include a financial crisis, can explain the cumulative four-year loss in the level of potential output following an output peak preceding a recession. The main result is that the depth of a recession has a significant effect on the loss of potential for advanced countries, while the length is important for emerging markets. These results imply that the Great Recession might have resulted in declines in trend output growth averaging about 3 percent for the advanced economies, but appear to have had little effect on emerging market trend growth.

The Use Of Cyclical Indicators In Estimating The Output Gap In Japan

The paper uses capital and labor utilization rates to derive estimates of the Japanese output gap and potential output. Two techniques are used. The first uses the cyclical indicators to adjust potential output estimates derived from a Hodrick-Prescott filter over the most recent period when such estimates are generally considered to be unreliable. The second estimates equilibrium levels of the cyclical indicators and uses an Okuns Law-type relationship to derive output gaps and potential output. The second method is also applied to the components of potential output to derive a third estimate. These methods suggest that the current Japanese output gap is considerably larger than a simple Hodrick-Prescott filter would suggest.

Empirical Estimation of Trend and Cyclical Export Elasticities

This paper uses an adaptation of Vahid and Engles common trend/common cycle analysis to estimate trend and cyclical export elasticities for trading partner income and real exchange rates for 36 countries. For the countries for which both types of income elasticities can be identified, the cyclical elasticity is on average more than twice as large as the trend elasticity. The methodology is applied to forecasting exports during the recent cycle and it appears to improve on simpler models for about half of the countries. For an aggregate of all of the countries for which separate elasticities can be identified, the RMSE is about half as large for the trend/cycle model as for the simple model.

Have Global Value Chains Contributed to Global Imbalances

Global value chains (GVCs) have grown rapidly over the past several decades. Over the same period, the aggregate value of current account imbalances has risen substantially. This paper looks at whether these developments are related. While there is a sizable literature that has documented the rise of global production networks, there have been few attempts to assess the potential effect on global imbalances. The paper uses measures of GVCs developed in the literature in panel regressions to assess the effect on global imbalances over the period 1995-2011. It is argued that these variables should be entered as a product rather than individually and that they should be lagged, not contemporaneous with the change in current account balances. The results suggest that GVC position weighted by participation and trade share is negatively related to a countrys current account balance, i.e., moving upstream in the production process is negative for a countrys current account. However, the effects on global imbalances over the period studied appear to be small.

Cyclically Adjusted Current Account Balances

The Great Financial Crisis coincided with a sizable reduction in global external imbalances, defined as the absolute value of the sum of individual country current account surpluses and deficits relative to global GDP. Although current account balances should not respond to a downturn that is uniform across countries, one that hits countries with current account deficits harder than those with surpluses might result in a decline in the global balance. This paper quantifies the cyclical portion of the current account balance for 35 countries using estimates of the severity of the cycle in each country relative to that of its trading partners in conjunction with three estimates of the sensitivity of the current account balance to changes in the output gap. Two of the estimates are derived from equations linking trade to income and the third is derived from the relationship between changes in current account balances and changes in output gap differentials. The main result is that the bulk of the reduction in the global current account imbalance since 2006 appears to have been structural. Cyclical forces are estimated to account for between 10 and 30 percent of the decline. In the aggregate, the cyclical effect is estimated to be currently holding down the global current account balance by about 1/2 percentage point. However, the size of the cyclical effect is more substantial for some countries. Both surplus and deficit countries have contributed to the decline in the absolute value of the global current account imbalance, but the contribution of the deficit countries is about twice as large as that of the surplus countries. Changes in oil prices have had largely offsetting effects on the global current account balance, but changes in real exchange rates in recent years have contributed to the reduction.
