We theoretically and empirically examine how firms’ choices of wage-setting protocols respond to labor market conditions.

We theoretically and empirically examine how firms’ choices of wage-setting protocols respond to labor market conditions. We develop a simple model in which workers may be able to send multiple job applications and firms choose between posting wages and Nash bargaining. Posting a wage allows the firm to commit to lower wages than would be negotiated ex post, but eliminates the ability to respond to a competing offer, should the worker have one. We show that higher productivity lowers both the application-vacancy ratio and the fraction of firms posting a wage. On the other hand, an increase in the number of applications per worker raises the application-vacancy ratio while lowering the fraction of firms posting a wage. As a result, the equilibrium fraction of firms posting a wage may be positively or negatively correlated with the application-vacancy ratio, depending on the source of shocks. The model also implies that an increase in the number of applications per worker may lead to a decrease in the number of posting firms rather than a change in the wages posted by those firms. Empirically, we demonstrate that the model’s predictions are confirmed in a novel dataset from an online job board.

Multinational affiliates are more productive than domestic firms, so how do they affect a host country through the labor market?

Multinational affiliates are more productive than domestic firms, so how do they affect a host country through the labor market? We use data for Norway to show that the labor market is characterized by a job ladder, with multinationals on the upper rungs. We calibrate a general equilibrium job ladder model with endogenous multinational entry to the Norwegian data. In a counterfactual where multinationals face an infinite entry cost, payments to labor fall and profits of domestic firms rise, but the impact is heterogeneous. Competition for workers increases low down on the job ladder, while it decreases high up.

Black workers experience a higher unemployment rate, as well as more volatile employment dynamics, than white workers.

Black workers experience a higher unemployment rate, as well as more volatile employment dynamics, than white workers, and the racial unemployment rate gap is largely unexplained by observable characteristics. We develop a New Keynesian model with search and matching frictions in the labor market, endogenous separations, and employer discrimination against Black workers to explain these outcomes. The model is consistent with key features of the aggregate economy and is able to explain key labor market disparities across racial groups. We then use this model to assess the effects of the Federal Reserve's new monetary policy framework—interest rates respond to shortfalls of employment from its maximum level rather than deviations—on racial inequality in the labor market. We find that shifting from a Deviations interest rate rule to a Shortfalls rule reduces the racial unemployment rate gap and the model-based measures of labor market discrimination but increases the average inflation rate. From a welfare perspective, we find that the Shortfalls approach does not do much to reduce racial inequality in our model economy.

The recent surge in inflation led many unions and firms to alter their bargaining and wage-setting policies.

The recent surge in inflation led many unions and firms to alter their bargaining and wage-setting policies. Using novel German firm-level survey data, we document the extent of state dependency of wage-setting behavior across firms and workers given high vs. low inflation environments. The granularity of our micro-level data also allows us to study heterogeneous patterns across sectors, firms, and workers. Embedding the empirical findings in a New Keynesian model with heterogeneous firms, we then analyze the implications of state-dependent wage-setting behavior for the transmission and propagation of shocks. Lastly, we discuss the interaction of state-dependent wage setting with firms' monopsony power and how these features impact monetary policy and the slope of the Phillips curve.

We build a large new Keynesian OLG model with a realistic age structure, labor market frictions, sticky prices, and aggregate shocks.

We study the link between the evolving age structure of the working population and unemployment. We build a large new Keynesian OLG model with a realistic age structure, labor market frictions, sticky prices, and aggregate shocks. Once calibrated to the European economy, we quantify the considerable extent to which demographic changes over the last 30 years contribute to the decline of unemployment rate. Our findings have important policy implications given the expected aging of the working population in Europe. Furthermore, lowering inflation volatility is less costly in terms of higher unemployment volatility. It suggests that optimal monetary policy is more hawkish in the older society. Our results hint also at a partial reversal of the European-US unemployment puzzle due to the fact that in the US the share of young workers is expected to remain robust.

This paper analyzes the open-economy spillover effects of labor market reforms under incomplete insurance. Using microeconomic data, we document a boost in the tradable sector in the aftermath of the German Hartz IV reform. In our model, this phenomenon can be explained by an increase in household savings due to higher precautionary savings in response to the reduction in the generosity of unemployment insurance (Hartz IV). Besides reducing unemployment in the reforming country, lower unemployment benefits generate long-run negative consumption spillovers in a monetary union, which we call the dark shadow of labor market reforms. Our model can match various German trends post Hartz IV reform, such as: i) a lasting increase in net foreign asset position, ii) short-term expansion of the tradable sector relative to the non-tradable sector, and iii) continued depreciation of the real exchange rate. By contrast, simulations of German wage moderation result in qualitatively different open-economy effects that are not in line with the empirical patterns for Germany.

We study the role of labor market beliefs in the gender pay gap. We find that, on average, women expect to receive lower salaries than men and also expect to receive fewer offers when employed. 

We study the role of labor market beliefs in the gender pay gap. We find that, on average, women expect to receive lower salaries than men and also expect to receive fewer offers when employed. Gender differences in expectations explain a sizable fraction of the residual gap in reservation wages. We estimate a partial equilibrium job search model that incorporates worker heterogeneity in beliefs about the wage offer distribution, arrival rates, and separation rate. Counterfactual exercises show that labor market beliefs play an important role in the gender wage gap, but matter little for the gender differences in welfare. Eliminating gender differences in the actual offer distribution, by contrast, decreases the gender gap in pay and welfare.

Numerous governments provide income-contingent childcare subsidies.

Numerous governments provide income-contingent childcare subsidies. In this paper, we estimate the dynamic marginal efficiency cost of redistribution (MECR) associated with a large-scale program of this kind in Germany, and compare them with the MECR associated with the benchmark redistributive tool, the income tax. To do so, we integrate methods from public finance theory into a dynamic structural heterogeneous-household model of childcare demand and maternal labor supply. We also incorporate social mobility concerns into the MECR and find the MECR of the childcare subsidies to be significantly lower at the margin, suggesting that childcare subsidies are the more efficient redistributive tool.

EU Eastern Enlargement elicited a rise in (temporary) labour market oriented immigration to Germany starting in May 2011. Taking into account that not all immigrants stay permanently and that outmigration flows are selective, this paper classifies recent EU immigrants into “new arrivals” and “stayers” drawing on administrative social security data (2005-2017). This novel strategy allows us to separately identify their potentially opposing short- and medium-run effects on labour market outcomes in Germany. We find a transitory negative wage effect among German nationals, particularly at the bottom of the wage distribution; and a permanent positive effect on full-time employment.

We combine novel micro data with quasi-random timing of patent decisions over the business cycle to estimate the effects of the Great Recession on innovative startups. After purging ubiquitous selection biases and sorting effects, we find that recession startups experience better long-term outcomes in terms of employment and sales growth (both driven by lower mortality) and future inventiveness. While funding conditions cannot explain differences in outcomes, a labor market channel can: recession startups are better able to retain their founding inventors and build productive R&D teams around them.
