Nominal Wage Flexibility and Economic Performance: Evidence and Implications Across Industrial Countries

By considering the theoretical connection between labour and product markets, the paper evaluates the economic relationship of these markets within the contractual wage rigidity New Keynesian explanation of business cycles. The empirical analysis focuses on the short‐run cyclical behaviour of real output, prices and wages for 19 industrial countries. Time‐series and cross‐sectional regressions are estimated. Cross‐sectional cyclical correlations in the labour and goods markets are also evaluated across countries. Consistent with the theoretical predictions, aggregate uncertainty is an important factor in increasing the flexibility of the nominal wage in response to aggregate demand shocks. Wage flexibility accelerates price inflation and moderates the response of real output growth to aggregate demand shocks. Wage flexibility does not appear to be an important factor in differentiating the real and inflationary effects of energy price shocks across countries. Finally, aggregate uncertainty increases the responsiveness of output and price to productivity shocks.     

Countercyclical or procyclical real wages? A disaggregate explanation of aggregate asymmetry

The time-series analysis of disaggregated data for a sample of 28 private industries verifies the prevalence and sources of asymmetry in aggregate data. The evidence indicates that asymmetry in the cyclical behavior of the real wage is widespread across the U.S. economy. The reduction in the real wage during recessions appears pronouncedly larger compared to the increase in the real wage during expansions in many industries. Across industries, price inflation increases faster compared to nominal wage inflation in the face of higher demand variability. Price flexibility moderates the increase in the real wage and output growth during expansions. In contrast, prices appear more downwardly rigid compared to the nominal wage in the face of demand variability. Price rigidity exacerbates the reduction in the real wage and output contraction during recessions. The combined evidence supports the implications of the sticky-price explanation of business cycles.First version received: June 2003/Final version received: June 2004The author thanks an anonymous referee for helpful comments on an earlier draft of the paper.

Nominal inertia and shock persistence in UK business cycles

A structural VAR methodology is used for UK data to identify and map out the effects of innovations in the money supply, employment, output, wages and prices. Moreover, bands of two standard errors are computed for the impulse response functions so that comment may be made on the significance of the dynamic responses of the variables to the simulated shocks. This allows conclusions to be drawn on the persistence of shocks. Results suggest that output variation is largely determined by aggregate demand shocks over the business cycle frequency. Importantly, evidence is also found of rigidities in the form of price inertia and nominal wage stickiness.     

Increased price flexibility and output stability

Simulation results of previous authors show an ambiguous effect of increased price flexibility on output stability in models incorporating a Mundell inflation effect on aggregate demand. This paper interprets their results in an analytically tractable model with imperfect, goods-market competition. To be destabilizing, increased flexibility must increase the “hump” of the price level's response to demand shocks. Output variability is always reduced by increasing the size of the flex-price sector and sometimes reduced by shortening contract lengths in the fix-price sector.     

Oil Prices, Terms of Trade Shocks, and Macroeconomic Fluctuations in Saudi Arabia

The article investigates the sources of macroeconomic fluctuations in Saudi Arabia using structural vector autoregression methods and pays particular attention to oil prices and changes in terms of trade. Using a macroeconomic model tailored to the Saudi Arabian economy, the authors identify terms of trade, supply, balance of payments, aggregate demand, and monetary shocks. The results show that the Saudi Arabian price level, real exchange rate, and to a lesser extent output is vulnerable to terms of trade shocks. Moreover, Saudi Arabian terms of trade are driven by output, trade balance, and aggregate demand shocks. To stabilize output and the real exchange rate, Saudi Arabia ought to continue diversifying its production base and aim for a stable nominal oil price. (JEL E32 , Q43 , C22 )     

Fractionalization and long-run economic growth: webs and direction of association between the economic and the social -- South Africa as a time series case study

In this paper it is considered that the relationship between nominal exchange rate and prices depends on the nature of the shocks impacting the economy. In order to identify the sources of nominal exchange rate and relative price fluctuations we impose long-run restrictions on the dynamics of these variables through a 2-variable and 3-variable SVAR, respectively. This methodology is applied to data on the Spanish economy and find that supply and real demand shocks move nominal exchange rates and relative prices in opposite directions. Nominal shocks, however, move both variables in the same direction. Thus, in this case, only under nominal shocks may exchange rate depreciations fuel inflation.

Wage bargaining and shock sensitivity of a small open economy

This paper analyzes the effects of centralized bargaining over a nominal wage (indexation) rule on a small open economy with fixed exchange rates. It is shown that the relative bargaining power of the confederation of employers and the union, respectively, affects not only the level of the endogenous variables but also their reaction to exogenous disturbances. If the union's power exceeds a critical value, positive aggregate demand shocks increase unemployment since the actual nominal wage rises more than the market clearing one. Moreover, if the union's power is sufficiently close to its upper bound, the overreaction of wages becomes so large that positive aggregate demand shocks even lead to a decrease in output and employment, i.e., the multipliers become negative.     

The Effect of Nominal Demand Shocks on Manufacturing Output: Evidence from Disaggregated Australian Data*

The menu costs model predicts that during times of rapid inflation firms are less likely to vary output in response to changes in nominal aggregate demand. This paper tests the proposition using a disaggregated sample of Australian three-digit ASIC manufacturing industries. The results show that a significant number of Australian industries exhibit behaviour that is consistent with this prediction. In addition, the results show that the variability of inflation and changes to the import penetration ratio also influence the response of output to nominal demand changes.     

The sectorial impact of commodity price shocks in Australia

This study reports that commodity price shocks predominantly affect the mining, construction and manufacturing industries in Australia. However, the financial and insurance sectors are found to be relatively unaffected. Mining industry profits and nominal output substantially increase in response to commodity price shocks. Construction output is also found to increase significantly, especially in response to a bulk commodity shock, as a result of increased demand for resource related construction. Increased demand for construction has a positive spillover effect to the parts of the manufacturing industry that supply the construction sector with intermediate inputs, such as the non-metallic mineral sub-industry. In contrast, other manufacturing sub-industries with only tenuous links to the resources sector such as textiles, clothing and other manufacturing, are relatively unresponsive to commodity price shocks.     

The impact of productivity and demand shocks on structural dynamics: Evidence from Austrian manufacturing

Based on Pasinetti's model of structural dynamics we develop an empirical identification strategy for aggregate and sectoral labor productivity and demand shocks in a structural vector autoregressive model with long-run restrictions. Impulse response analysis shows that we can distinguish four patterns of the effects of changes in demand and productivity growth on sectoral output growth. For some industries demand is indeed the factor driving sectoral growth. Labor productivity and demand shocks are closely associated with the growth rates of employment and output across industries. However, there is less correlation with entry and exit. This suggest that structural change within and between industries may have quite different determinants.     

Imperfect credibility,sticky wages,and welfare

This paper studies optimal monetary policy under imperfect credibility in a New Keynesian model with staggered price and wage setting. In our imperfect credibility framework, the central bank commits to a policy plan but occasionally reneges on past promises with a given common knowledge probability. We find that the welfare gains from increasing credibility are approximately linear on the initial credibility level. We also find that the output-inflation stabilisation trade-off is nonmonotonic as higher credibility does not always reduce output volatility. The variance decomposition shows that wage markup shocks are the main driver of economic fluctuations and that these shocks are better contained, even in relative terms, when credibility is high. We then show that the degree of credibility impacts the effect of wage flexibility on welfare. When credibility is low, monetary policy is less potent and the economy can experience a feedback loop between wage volatility and price volatility. We show, though, that once wage markup shocks are taken into account, wage flexibility is usually welfare improving.     

Shocking the eurozone

In this paper, the monetary transmission mechanism within the European Monetary Union is investigated. The impulse response functions and forecast error variance decompositions of a structural vector error correction model (SVECM) are compared with those of a New Keynesian theoretical model. The identifying restrictions of the SVECM are directly derived from the theoretical model. Two permanent shocks are identified, one having only nominal, and one having only real effects. The three transitory shocks comprise a short-term interest-rate shock, an aggregate demand shock and a money demand shock. The main conclusions are that permanently reducing the inflation objective depresses output in the first year, but has no real effects in the long run. Regarding output variability, the results indicate that aggregate demand shocks are most important during the first year, after which aggregate supply shocks dominate.     

中国劳动力市场名义工资粘性程度的估算

本文完成了对中国劳动力市场名义工资粘性程度的首次估算,发现中国的名义工资粘性处于世界较低水平。这具有重要的宏观政策含义:一方面表明中国的劳动力市场具有很强的"自我调节"经济波动的特性,另一方面说明中央银行扩张性的货币政策将更多地带来物价水平上涨,而不是产出增加。在此基础上,本文还区分了劳动者的收入、工龄、户口、企业类型、行业等特征,对不同人群的工资粘性进行了细致测算。进一步,本文创新地区分并估算了名义工资的向上粘性与向下粘性,发现自2002年以来,中国劳动力市场的向下粘性不断增大,而向上粘性的变化趋势并不明显。     

USLNG FUTURES INSTRUMENT PRICES TO TARGET NOMINAL INCOME

Nominal GNP targeting offers the advantage of allowing monetary policymakers to offset velocity shocks and cushion the impact of autonomous price shocks. Instability associated with the recognition lag can be minimized by fixing a futures instrument price linked to nominal GNP. In fact, if financial markets arc efficient, then a policy of fixing futures instrument prices would seem preferable to a policy feedback mechanism for any economic aggregate target which involves a recognition lag. This conclusion is robust with respect to a wide range of macroeconomic models.     

Observed expectations,news shocks,and the business cycle

This paper exploits information from the term structure of survey expectations to identify news shocks in a DSGE model with rational expectations.We estimate a structural business-cycle model with price and wage stickiness. We allow for both unanticipated and anticipated components (“news”) in each structural disturbance: neutral and investment-specific technology shocks, government spending shocks, risk premium, price and wage markup shocks, and monetary policy shocks.We show that the estimation of a standard DSGE model with realized data obfuscates the identification of news shocks and yields weakly or non-identified parameters pertaining to such shocks. The identification of news shocks greatly improves when we re-estimate the model using data on observed expectations regarding future output, consumption, investment, government spending, inflation, and interest rates - at horizons ranging from one-period to five-periods ahead.The news series thus obtained largely differ from their counterparts that are estimated using only data on realized variables. Moreover, the results suggest that the identified news shocks explain a sizable portion of aggregate fluctuations. News about investment-specific technology and risk premium shocks play the largest role, followed by news about labor supply (wage markup) and monetary policy.

The business cycle with nominal contracts

Summary In this paper we study the quantitative implications of nominal wage contracts for business cycle fluctuations. We address this issue using a model economy based on the neoclassical growth model supplemented by the assumption that cash is needed to purchase goods. We consider a variation of the standard recursive competitive equilibrium concept that is intended to capture the important features of wage contracting. We use this equilibrium construct to address three issues. First, we consider whether monetary shocks, propagated by nominal contracts, constitute a viable alternative to technology shocks as a source of aggregate fluctuations. Our results suggest that, while monetary shocks and nominal rigidities succeed in causing output volatility of the required magnitude, the resulting data have properties that are inconsistent with several key features of U.S. data. Second, we consider how the behavior of the economy varies with contract length. We find that the volatility induced by both monetary and technology shocks increases sharply with contract length. Finally we consider how much rigidity would be necessary to match the volatility of U.S. output. We find that only a very small amount of rigidity would be necessary to cause output volatility of the magnitude observed.We have received helpful comments from David Chapman, Paul Gomme, Jeremy Greenwood, Gary Hansen, Michael Keane, Tim Kehoe, Lee Ohanian, Edward Prescott, and Warren Weber.

A Note on Inflation Targeting

The authors present a pedagogical graphical exposition to illustrate the stabilizing effect of price target zones. Based on a textbook AD-AS apparatus, they find that authorities' commitment to defend a price target zone will affect the public's inflation expectations and, in turn, reduce actual inflation. They also find that, when the economy experiences supply shocks, the announcement that the monetary authorities intend to defend a price target zone will reduce the variability of domestic prices but raise the variability of domestic output relative to a free-price regime. However, when the economy experiences demand shocks, a price target zone tends to lower the variability of both domestic prices and out-put relative to a free-price regime.
