Welfare costs of sticky wages when effort can respond (original) (raw)

Cyclical Movements in Hours and Effort Under Sticky Wages

International Economic Journal, 2001

We examine the response of a sticky-wage economy to various real and nominal shocks. In addition to variations in hours, we allow for an endogenous response in worker effort per hour. Despite wages being predetermined, the labor market clears through the effort margin. We find that the ability of a sticky-wage model to mimic U.S. business cycles is much improved by allowing for reasonable effort movements. The model also provides a ready explanation for the finding that TFP is negatively affected by nominal shocks. * We thank Jang-Ok Cho, Youngsik Kim, Pete Klenow, and Kwanho Shin for helpful comments.

Patterns of nominal and real wage rigidity

Research in Labor Economics, 2010

We study the distortions that downward nominal and real wage rigidity would induce to a flexible form of a notional, rigidity-free, distribution of wage change using the histogram-location approach. We examine alternative methods of generating the histograms that support the econometric search for rigidity distortions and implement our approach to inflation sub-periods that should be characterised by different patterns of nominal and real rigidities. We establish the general applicability of the approach to these sub-periods and find results consistent with expectations.

Downward Nominal Wage Rigidity: The Implications from a New-Keynesian Model

2006

We study the determinants of Downward Nominal Wage Rigidity (DNWR) in the context of a new-Keynesian heterogeneous-agent model. Labor productivity of agents is subject to perfectly insurable idiosyncratic shocks. Wage contracts are signed one period ahead and specify the minimum wage that the firm should pay to each worker conditional on her future expected marginal product. The model predicts a simple structural equation: the degrees of DNWR are entirely determined by unexpected shocks to technology and money supply. We test this model's implication with data on the U.S. economy, and we find that the above two shocks can account for about 60% of variation in the aggregate measures of DNWR.

Can Competitive Forces Reinforce Nominal Wage Rigidities?

While rigidities in nominal factor costs imply a finite slope in the aggregate supply curve, this paper asks, " Do rigidities increase if there is a more competitive economy? " Several authors claim that real rigidities of monopoly power reinforce nominal rigidities due to price adjustment costs. This paper argues almost the opposite: that " real rigidities " due to competition (i.e., lack of monopoly power) reinforce nominal rigidities when firms are reluctant to raise prices due to competitive pressure. In the model, nominal factor costs are stickier than output prices. Thus risk-averse firms are slower to raise output prices than to lower them. JEL Classification: E12

Interacting nominal and real labour market rigidities

Economics Letters, 2011

This note investigates the interaction between nominal and real labour market rigidities. It shows nominal wage rigidity to have little effect on the welfare loss from labour adjustment costs under a labour supply shock. This implies that the second best effect of nominal price stickiness under real wage persistence studied in Duval and Vogel (2007) does not apply to the propagation of supply shocks under nominal wage rigidity and labour adjustment costs.

How strong is the macroeconomic case for downward real wage rigidity

Journal of Monetary Economics, 2009

We explore the existence of drwr at the industry level, based on data from 19 oecd countries for the period 1973-99. We find that drwr compresses the distributions of industry wage changes overall, as well as for specific geographical regions and time periods, but there are not many real wage cuts that are prevented. More important, however, drwr attenuates larger real wage cuts, thus leading to higher real wages. We find stronger evidence for downward nominal wage rigidity than for drwr. There is evidence that real wage cuts are less prevalent in countries with strict employment protection legislation and high union density.

Wage setting actors and sticky wages: Implications for the business cycle and optimal monetary policy

Economic Modelling, 2009

Two sticky-wage models are introduced in this paper to examine the implications of having either households or firms as wage setting actors. The rate of wage inflation depends positively on the output gap if households set wages whereas such a relationship is of negative sign when firms set wages. Moreover, impulse-response functions and the statistical comparison with US data show different business cycle properties depending upon wage setting actors. Finally, optimal monetary policy is derived for each case, and compared with a Taylor-type monetary policy rule.
