Land prices and unemployment

We integrate the housing market and the labor market in a dynamic general equilibrium model with credit and search frictions. We argue that the labor channel, combined with the standard credit channel, provides a strong transmission mechanism that can deliver a potential solution to the Shimer (2005) puzzle. The model is confronted with U.S. macroeconomic time series. The estimation results account for two prominent facts observed in the data. First, land prices and unemployment move in opposite directions over the business cycle. Second, a shock that moves land prices also generates the observed large volatility of unemployment.     

Downward Nominal Wage Rigidity and Determinacy of Equilibrium

It is well known in the literature that there is a tension between the frequency and duration of the zero lower bound (ZLB) on the nominal interest rate and the determinacy of equilibrium. In this short paper, I show that the presence of downward nominal wage rigidity (DNWR) resolves the tension by preventing a vicious cycle of price declines and output contractions under the ZLB. Consequently, the model with DNWR can replicate the long-lived ZLB episodes observed in the data. It also implies a plausible size of output and inflation declines at the ZLB.     

Downward Nominal Wage Rigidity and Inflation Dynamics during and after the Great Recession

In this paper, I develop a New Keynesian model that embeds heterogeneous workers with asymmetric wage adjustment costs to address two inflation puzzles: missing deflation during the Great Recession and the subsequent missing inflation. When the wage adjustment costs are estimated according to U.S. microwage data, downward nominal wage rigidity emerges, which flattens the observed price Phillips curve during and after recessions. Endogenous evolution of the cross-sectional wage distribution generates nonlinear dynamics including the sign, size, and state dependence. These nonlinearities enable the model to address the inflation puzzles as well as matching microevidence on wage adjustments.     

Inflation and labor market dynamics revisited

We demonstrate that the presence of an empirically plausible labor adjustment decision at the firm level rationalizes strategic complementarities in price-setting which help explain inflation dynamics. Those strategic complementarities are typically assumed away in the related existing literature. This motivates our revisiting of inflation and labor market dynamics.     

Macroeconomic dynamics in a model of goods,labor, and credit market frictions

Goods market frictions drastically change the dynamics of the labor market, both in terms of persistence and volatility. In a model with three imperfect markets – goods, labor, and credit – we find that credit and goods market imperfections are substitutable in raising volatility. Goods market frictions are unique in generating persistence. Two key mechanisms in the goods market generate large hump-shaped responses to productivity shocks: countercyclical goods market tightness and prices alter future profit flows and raise persistence; procyclical search effort of consumers and firms raises amplification. Goods market frictions are thus key in understanding labor market dynamics.     

Employment protection, firm selection, and growth

How do firing costs affect aggregate productivity growth? To address this question, a model of endogenous growth through selection and imitation is developed. It is consistent with recent evidence on firm dynamics and on the importance of reallocation for productivity growth. In the model, growth is driven by selection among heterogeneous incumbent firms and is sustained as entrants imitate the best incumbents. In this framework, firing costs not only induce misallocation of labor, but also affect growth by affecting firms’ exit decisions. Importantly, charging firing costs only to continuing firms raises growth by promoting selection. Also charging them to exiting firms is akin to an exit tax, hampers selection, and reduces growth—by 0.1 percentage points in a calibrated version of the model. With job turnover very similar in the two settings, this implies that the treatment of exiting firms matters for growth. In addition, the impact on growth rates is larger in sectors where firms face larger idiosyncratic shocks, as in services. This fits evidence that recent EU-U.S. growth rate differences are largest in these sectors and implies that firing costs can play a role here.     

Labour market conditions and the corporate financing decision: A European analysis

This study examines the influence of labour market conditions on corporate capital structure in a sample of 2892 firms from France, Germany, Italy, Spain, and the UK. After considering the effect of unemployment and inflation, we analyse the impact of two market imperfections: employees’ rights and downward wage rigidity. Results indicate that financial leverage responds to changes in unemployment and inflation. We also find that the influence of employees’ rights is non-linear, whereas the negative effect of downward wage rigidity is moderated by firms’ market power. Taken together, our results show that corporate financial decisions are conditioned not only by firm-level issues but also by a country’s labour market.     

Optimal monetary policy in a small open economy with staggered wage and price contracts

We study optimal monetary policy for a small open economy in a model where both domestic prices and wages are sticky due to staggered contracts. The simultaneous presence of the two forms of nominal rigidities introduces an additional trade-off between domestic inflation and the output gap. We derive a second-order approximation to the average welfare losses that can be expressed in terms of the unconditional variances of the output gap, domestic price inflation, and wage inflation. As a consequence, the optimal policy seeks to minimize a weighted average of these variances. We analyze welfare implications of several alternative simple policy rules, and find that domestic price inflation targeting generates relatively large welfare losses, whereas CPI inflation targeting performs nearly as well as the optimal rule.     

Consumption heterogeneity,employment dynamics and macroeconomic co-movement

Real-business-cycle models rely on total factor productivity (TFP) shocks to explain the observed co-movement among consumption, investment and hours. However an emerging body of evidence identifies “investment shocks” as important drivers of business cycles. This paper shows that a neoclassical model consistent with observed heterogeneity in labor supply and consumption across employed and non-employed can generate co-movement in response non-TFP shocks. Estimation reveals fluctuations in the marginal efficiency of investment that explain the bulk of business-cycle variance in consumption, investment and hours. A corollary of the model׳s empirical success is the labor wedge that is not important at business-cycle frequencies.     

Stock market volatility and business cycle: Evidence from linear and nonlinear causality tests

This paper investigates the relationship between stock market volatility and the business cycle in four major economies, namely the US, Canada, Japan and the UK. We employ both linear and nonlinear bivariate causality tests and we further conduct a multivariate analysis to explore possible spillover effects across countries. Our results suggest that there is a bidirectional causal relationship between stock market volatility and the business cycle within each country and additionally reveal that the recent financial crisis plays an important role in this context. Finally, we identify a significant impact of the US on the remaining markets.     

Market Imperfections,Macroeconomic Conditions,and Capital Structure Dynamics: A Cross-Country Study

This article investigates how “systematic” adjustment costs proxied by market imperfections, and macroeconomic conditions affect capital structure dynamics in a cross-country setting. We document substantial variations in firms’ capital structure adjustments across countries and, particularly, over time. Consistent with adjustment costs impeding firms from rebalancing their capital structures, worse market imperfections are associated with slower speeds of adjustment (SOA) and larger leverage deviations. Intertemporally, capital structure adjustment is procyclical, with SOA increasing by 0.9 percentage point for a one-percentage-point increase in GDP growth rate. The procyclicality is attributable to good macroeconomic conditions mitigating market imperfections through channels of 1) facilitating free-ride restructuring and 2) uncertainty alleviation. Our investigation features a bootstrapping-based estimation method that addresses the mechanical mean reversion of leverage ratio.     

The Role of Real Wage Rigidity and Labor Market Frictions for Inflation Persistence

We analyze the transmission mechanism of wages to inflation within a New Keynesian business cycle model with wage rigidities and labor market frictions. Our main focus is on the channel of real wage rigidities on inflation persistence for which we find the specification of the wage bargaining process to be of crucial importance. Under the standard efficient Nash bargaining, the feedback of wage rigidities on inflation is ambiguous and depends on other labor market variables. However, under the alternative right‐to‐manage bargaining we find that more rigid wages translate directly into more persistent movements of aggregate inflation.     

Unionization,product market competition,and strategic disclosure

We examine the disclosure policies of non-unionized firms operating in unionized industries. We test the hypothesis that non-unionized firms have an incentive to disclose more information when their unionized rivals are engaged in labor renegotiations; that is, to weaken them. We find that non-unionized firms disclose more information and more good news when renegotiations are ongoing. This behavior is stronger for larger firms, firms with fewer peers in the industry, and firms more similar to their renegotiating rivals. We also find some evidence that unionized firms are harmed by this behavior and that non-unionized firms benefit from their increased disclosures.     

The impact of (global) business cycle risk on the German and British stock markets: Evidence from the first age of globalization

In the period from 1880 to 1913, time-varying German and British stock market returns are related to business cycle variables such as the deviation of industrial production from trend. Common British and German business cycle dynamics Granger cause stock returns and explain more than 20% of time variation in one-year ahead stock market returns. The link between business cycle variables and stock returns is less pronounced in the modern era of financial globalization. A potential explanation for this finding is the fact that during the first globalization period stock indices were dominated by industrial companies and stock prices varied in line with dividends. In the modern era of globalization stock price dynamics predominantly reflect time-varying risk premia.
