Optimal Labor-Market Policy in Recessions

We examine the optimal labor market-policy mix over the business cycle. In a search and matching model with risk-averse workers, endogenous hiring and separation, and unobservable search effort we first show how to decentralize the constrained-efficient allocation. This can be achieved by a combination of a production tax and three labor-market policy instruments, namely, a vacancy subsidy, a layoff tax and unemployment benefits. We derive analytical expressions for the optimal setting of each of these for the steady state and for the business cycle. Our propositions suggest that hiring subsidies, layoff taxes and the replacement rate of unemployment insurance should all rise in recessions. We find this confirmed in a calibration targeted to the U.S. economy.unemployment , search and matching , endogenous separations

Resuscitating the wage channel in models with unemployment fluctuations

All else equal, higher wages translate into higher inflation. More rigid wages imply a weaker response of inflation to shocks. This view of the wage channel is deeply entrenched in central banks’ views and models of their economies. In this paper, we present a model with equilibrium unemployment which has three distinctive properties. First, using a search and matching model with right-to-manage wage bargaining, a proper wage channel obtains. Second, accounting for fixed costs associated with maintaining an existing job greatly magnifies profit fluctuations for any given degree of wage fluctuations, which allows the model to reproduce the fluctuations of unemployment over the business cycle. And third, the model implies a reasonable elasticity of steady state unemployment with respect to changes in benefits. The calibration of the model implies low profits, but does not require a small gap between the value of working and the value of unemployment for the worker.

The (un)importance of unemployment fluctuations for welfare

This paper develops a real business cycle model with labor market search and matching frictions, which endogenously links both the cyclical fluctuations and the mean level of unemployment to the aggregate business cycle risk. The key result of the paper is that business cycles are costly for all consumers, regardless of their wealth, yet that unemployment fluctuations themselves are not the source of these costs. Rather fluctuations over the cycle induce higher average unemployment rates as employment is non-linear in job-finding rates and past unemployment. The authors first show this result analytically in special cases. They then calibrate a general equilibrium model with risk-averse asset-holding and liquidity-constrained workers to US data. Also under these more general circumstances, business cycles mean higher unemployment for all workers. The ensuing costs of cycles rise further for liquidity-constrained agents when replacement rates are lower or when workers' skills depend on the length of (un)employment spells.Unemployment ; Welfare ; Business cycles

Identifying the Role of Labor Markets for Monetary Policy in an Estimated DSGE Model

We focus on a quantitative assessment of rigid labor markets in an environment of stable monetary policy. We ask how wages and labor market shocks feed into the inflation process and derive monetary policy implications. Towards that aim, we structurally model matching frictions and rigid wages in line with an optimizing rationale in a New Keynesian closed economy DSGE model. We estimate the model using Bayesian techniques for German data from the late 1970s to present. Given the pre-euro heterogeneity in wage bargaining we take this as the first-best approximation at hand for modelling monetary policy in the presence of labor market frictions in the current European regime. In our framework, we find that labor market structure is of prime importance for the evolution of the business cycle, and for monetary policy in particular. Yet shocks originating in the labor market itself may contain only limited information for the conduct of stabilization policy.Labor Market, Wage Rigidity, Bargaining, Bayesian Estimation

The role of labor markets for Euro area monetary policy

In this paper, we explore the role of labor markets for monetary policy in the euro area in a New Keynesian model in which labor markets are characterized by search and matching frictions.> We first investigate to which extent a more flexible labor market would alter the business cycle behavior and the transmission of monetary policy. We find that while a lower degree of wage rigidity makes monetary policy more effective, i.e. a monetary policy shock transmits faster onto inflation, the importance of other labor market rigidities for the transmission of shocks is rather limited. Second, having estimated the model by Bayesian techniques we analyze to which extent labor market shocks, such as disturbances in the vacancy posting process, shocks to the separation rate and variations in bargaining power are important determinants of business cycle fluctuations. Our results point primarily towards disturbances in the bargaining process as a significant contributor to inflation and output fluctuations. In sum, the paper supports current central bank practice which appears to put considerable effort into monitoring euro area wage dynamics and which appears to treat some of the other labor market information as less important for monetary policy.Labor market - Europe ; European Union countries ; Monetary policy - Europe

Optimal monetary policy rules for the euro area: an analysis using the area wide model

In this paper, we analyze optimal monetary policy rules in a model of the euro area, namely the ECB’s Area Wide Model, which embodies a high degree of intrinsic persistence and a limited role for forward-looking expectations. These features allow us, in large measure, to differentiate our results from many of those prevailing in New Keynesian paradigm models. Speci?cally, our exercises involve analyzing the performance of various generalized Taylor rules both from the literature and optimized to the reference model. Given the features of our modelling framework, we ?nd that optimal policy smoothing need only be relatively mild. Furthermore, there is substantial gain from implementing forecast-based as opposed to outcome-based policies with the optimal forecast horizon for in?ation ranging between two and three years. Benchmarking against fully optimal policies, we further highlight that the gain of additional states in the rule may compensate for a reduction of communicability. Thus, the paper contributes to the debate on optimal monetary policy in the euro area, as well as to the conduct of monetary policy in face of substantial persistence in the transmission mechanism.

Real price and wage rigidities in a model with matching frictions

This paper incorporates search and matching frictions in the labor market into a New Keynesian model. In contrast to the literature, the labor market activity takes place in the (Calvo-staggered) price-setting sector. Matching frictions lead price-setting firms to negotiate wage rates with their employees. The negotiation of wages substantially increases strategic complementarity in price-setting among suppliers of differentiated goods. This leads to an increase in real rigidities as in Woodford (2003), which reduces the size of price changes optimally chosen by re-optimizing firms. The same factors which induce smooth inflation also dampen the adjustment of wages in response to shocks. In the search and matching framework this is key for explaining the highly responsive nature of vacancies in the data. Another interesting finding for the Phillips curve is that inflation is not only driven by an output gap but also by an employment gap – a feature usually neglected in empirical research. The modified model matches impulse responses of an SVAR for post Volcker-disinflation US data very well.
