INDUSTRIAL OUTPUT VARIABILITY AND REAL WAGE FLUCTUATIONS: DETERMINANTS AND IMPLICATIONS

The cyclical behavior of the real wage differentiates between the empirical validity of major new Keynesian sticky-wage and sticky-price explanations of business cycles. Across industries of the United States, an increase in price flexibility relative to wage flexibility correlates with a reduction in output fluctuations in the face of demand shocks. Further, industrial real output variability does not vary significantly with nominal wage flexibility. In contrast, an increase in price flexibility moderates industrial real output variability. Consistently, an increase in the real wage response to demand shocks correlates with an increase in industrial output variability. ( JEL E32, E31)     

DETERMINING OUTPUT AND INFLATION VARIABILITY: ARE THE PHILLIPS CURVE AND THE MONETARY POLICY REACTION FUNCTION RESPONSIBLE?

This study analyzes the policy parameters in a Taylor monetary policy reaction function and a Phillips curve equation to determine the variability of inflation and output. The theoretical and empirical investigations yield two key results. First, countries with large parameters in the monetary policy reaction function have low and stable inflation. Second, countries with flatter Phillips curves (i.e., those with a higher degree of price stickiness) have larger output variability. This article also examines the determinants of inflation and output variability as well as determinants of the slope of the Phillips curve.(JEL E32 , E52 )     

INFLATION AND ASYMMETRIC OUTPUT ADJUSTMENTS BY FIRMS

Using ordered probit analyses of a unique micro data set, we find evidence of output asymmetry that is systematically related to inflation and to price asymmetry. As predicted by theory, firms are more likely at higher rates of inflation to raise prices in response to positive cost and demand shocks and less likely to lower prices in response to negative cost and demand shocks. The expected effects of higher inflation on output asymmetry, however, come primarily from cost and demand increases and to a lesser (and statistically insignificant) extent from cost and demand decreases. (JEL E3, D4)     

ISLANDS, INDEXATION AND MONETARY POLICY

This paper develops a synthesized macroeconomic model that incorporates the local-global informational asymmetries of an "islands" economy into a setting characterized by endogenous wage indexation. In such an economy, agents are unable both to filter out the separate influences of demand and supply shocks on observed output prices and to distinguish between the separate price effects of local and aggregate disturbances, so that optimal wage indexation depends upon both the variances of supply and demand disturbances and the information-conditioned forecasts of agents. As a result, optimal monetary policy generally depends upon the variances of local and aggregate supply and demand.     

UNION POWER,COLLECTIVE BARGAINING,AND OPTIMAL MONETARY POLICY

We study Ramsey policies and optimal monetary policy rules in a dynamic New Keynesian model with unionized labor markets. Collective wage bargaining and unions' monopoly power amplify inefficient employment fluctuations. The optimal monetary policy must trade off between stabilizing inflation and reducing inefficient unemployment fluctuations induced by unions' monopoly power. In this context the monetary authority uses inflation as a tax on union rents and as a mean for indirect redistribution. Results are robust to the introduction of imperfect insurance on income shocks. The optimal monetary policy rule targets unemployment alongside inflation. (JEL E0, E4, E5, E6)     

THE CHANGING RESPONSIVENESS OF WAGES TO PRICE-LEVEL SHOCKS: EXPLICIT AND IMPLICIT INDEXATION

The article provides evidence for the U.S over the period 1961-84 that the responsiveness of nonunion wages to price-level shocks changes through time much as the degree of indexation in union contracts does, suggesting that there exists implicit as well as explicit indexation. When coupled with the result from previous research that indexation responds positively to inflation uncertainty, the findings indicate that greater inflation uncertainty may lead to reduced overall wage rigidity. In the context of a rational expectations model with long-term wage contracts, a decline in the effectiveness of an activist monetary policy could result.     

AGGREGATE PRICE SHOCKS AND FINANCIAL INSTABILITY: A HISTORICAL ANALYSIS

This article presents evidence on the relationship between price and financial stability. We construct an annual index of financial conditions for the United States, 1790–1997, and estimate the effect of aggregate price shocks on the index using a dynamic ordered probit model. We find that price-level shocks contributed to financial instability during 1790–1933 and that inflation rate shocks contributed to financial instability during 1980–97. The size of the aggregate price shock needed to alter financial conditions depends on the institutional environment, but we conclude that a monetary policy focused on price stability would contribute to financial stability.     

THE U.S. LABOR INCOME SHARE AND AUTOMATION SHOCKS

The causes and consequences of the 1964–2016 swings in the U.S. labor income share/labor share (LS) are parsed through the lens of a structural model estimated on aggregate and LS series jointly. Where conventional models fall short, the present model yields a counter-cyclical LS unconditionally and in response to demand and monetary policy shocks, as well as a small wage pro-cyclicality, via moderate wage indexation. Shifts in automation, workers' market power, investment efficiency, and the relative price of investment account for 54%, 24%, 6%, and 4% of LS fluctuations, respectively. Automation shocks explain the lion's share of the post-2007 cyclical LS tumble and 11% of output cycles, and generate a distinctive counter-cyclical labor response. (JEL E32, E25, E52)     

HEALTH CARE INFLATION AND ITS IMPLICATIONS FOR MONETARY POLICY

Motivated by recent findings on the cyclical movement of both health and health spending, we construct a general equilibrium model that distinguishes health care demand from the demand for other goods. Using this model, we are able to generate inflation dynamics and cyclicality of health that match the US data. When the model is subjected to an expansionary monetary policy shock, it yields different output and inflation responses compared with a two‐sector model with homogeneous demand. We show that the trade‐off between leisure and health spending plays an important role in model dynamics. The model further predicts different degrees of inflation stabilization across sectors when a shift in the monetary policy occurs. (JEL E52, E31, E32, I10)     

MONEY, CREDIT, and WAGES IN HYPERINFLATION: POST-WORLD WAR I GERMANY

An important feature of the German hyperinflation is the way in which accelerating monetization of both government and private debt by the Reichsbank fueled the inflation process. The stimulus to private credit demand arising from more rapid adjustment of money wages over this period is often ignored, however. The present empirical results strongly support the importance of wage pressures in augmenting fiscal influences on nominal money growth during 1920–1923. Our findings also suggest that wage claims provided the main conduit through which higher inflationary expectations were accommodated by faster rates of monetary expansion.     

An Examination of the Asymmetric Effects of Money Supply Shocks in the Pre–World War I and Interwar Periods

We test whether monetary shocks had asymmetric output effects before World War II. Ball and Mankiw (1994) show that expectations of persistent inflation under fiat money can explain why negative monetary shocks had larger effects than positive shocks after World War II. Consistent with this explanation, we find such asymmetry in the interwar period following the abandonment of the gold standard and before it, when agents arguably anticipated this development. We find no monetary asymmetry before World War I, which is consistent with Ball and Mankiw (1994), because under a credible gold standard, agents do not expect persistent inflation.     

THE SWINGS OF U.S. INFLATION AND THE GIBSON PARADOX

In recent business cycles, U.S. inflation has experienced a reduction of volatility and a severe weakening in the correlation to the nominal interest rate (Gibson paradox). We examine these facts in an estimated dynamic stochastic general equilibrium model with money. Our findings point at a flatter New Keynesian Phillips Curve (higher price stickiness) and a lower persistence of markup shocks as the main explanatory factors. In addition, a higher interest‐rate elasticity of money demand, an increasing role of demand‐side shocks, and a less systematic behavior of Fed's monetary policy also account for the recent patterns of U.S. inflation dynamics. (JEL E32, E47)     

CYCLICAL COMOVEMENTS IN INDUSTRIAL LABOR AND PRODUCT MARKETS: THEORY AND EVIDENCE

We establish the theoretical connection between industrial labor and product markets within the contractual wage-rigidity new Keynesian explanation of business cycles. We estimate time-series and cross-sectional regressions for 28 private two-digit (S.I.C.) industries and find: (i) greater uncertainty is associated with upward flexibility of the nominal wage and moderates the countercyclical response of the real wage to aggregate demand shocks; (ii) an upwardly rigid nominal wage response to energy price shocks reduces the real contractionary effects of these shocks; (Hi) downwardly inflexible nominal wages are associated with downwardly rigid prices in response to productivity shocks.     

ON INFLATION AND REAL PRICE VARIABILITY

This paper studies the consequences of costly price adjustments for the variability of real prices accompanying inflation. For constant-elasticity demand and cost of production it is shown that a higher demand, a lower cost of production, or a lower cost of price adjustment leads to less intertemporal variability of real prices. If the marginal cost of production does not increase "too" fast, then the average real price is less than the real price that would prevail in the absence of inflation; additionally, a higher demand, a lower cost of production, or a lower cost of price adjustment leads to a higher level of real prices.     

MONETARY INTEGRATION, INFLATION CONVERGENCE AND OUTPUT SHOCKS IN THE EUROPEAN MONETARY SYSTEM

Studies on monetary convergence in Europe have reached mixed conclusions, raising questions about whether the European Monetary System failed to expedite convergence, or whether convergence requires redefining. A definition of convergence is explored that conditions monetary policy on factors affecting real exchange rates. Inflation rates have converged, while unconditional monetary policies have not. Once conditioning factors are considered, much of the gap between inflation and monetary convergence is explained. Differences in output trends do not explain the gap, while velocity variability does. (JEL F33)     

SUPPLY SHOCKS AND THE INTEREST RATE

The classic example of a temporary supply shock is a failed agricultural harvest. Theoretically, adverse temporary supply shocks are predicted to raise the ex ante real interest rate; that is, a below-normal harvest raises the interest rate. Apparently, however, no one has tested this conclusion using agriculture as the supply shock. This paper examines nineteenth century French data and confirms the hypothesis that deviations from the "average" harvest have an inverse effect on the interest rate. It also finds that temporary fluctuations in government spending affect the interest rate: higher than normal government spending raises the interest rate.     

INTERNATIONAL PRICE BEHAVIOR AND THE DEMAND FOR MONEY

Oil prices, commodity prices and American monetary policy, the last operating through a variety of channels, have all figured prominently in explanations of the international inflation process in the late 1960s and early 70s. OUT major purpose in this paper is to test these various hypotheses. We do so in the context of a reduced-form rational-expectations price equation which we estimate for the United States and seven other industrial countries using quarterly data for the period 1955 through 1976.
The principal conclusion that emerges from this exercise is that movements in domestic money in these countries served as the key link in the inflation process. The factors that produced these monetary changes, however, differed among countries. Price shocks of various sorts were clearly of secondary importance.
The other important set of conclusions concerns the demand for money. In place of a traditional stock adjustment model, we used GLS with a second-order correction for autocorrelation. We believe this produced more plausible estimates of the parameters of the long-run demand function and of the adjustment process itself.     

LENDING RELATIONSHIPS AND MONETARY POLICY

Financial intermediation and bank spreads are the important elements in the analysis of business cycle transmission and monetary policy. We present a simple framework that introduces lending relationships, a relevant feature of financial intermediation that has been so far neglected in the monetary economics literature, into a dynamic stochastic general equilibrium model with staggered prices and cost channels. Our main findings are (a) banking spreads move countercyclically generating amplified output responses, (b) spread movements are important for monetary policymaking even when a standard Taylor Rule is employed, (c) modifying the policy rule to include a banking spread adjustment improves stabilization of shocks and increases welfare when compared to rules that only respond to output gap and inflation, and finally (d) the presence of strong lending relationships in the banking sector can lead to indeterminacy of equilibrium forcing the Central Bank to react to spread movements. (JEL E44, E52, G21)     

AN EQUILIBRIUM POLITICO-ECONOMIC MODEL

A politico-economic model is developed in which rationally formed forecasts are available to all traders. Systematic government policy is neutral, but a large majority of the electorate, those who adopt rationally formed forecasts but do not know the model, hold the government responsible for the economy's performance. Real and political shocks generate novel feedback effects due to anticipated regime changes. These feedback effects may amplify or dampen the initial shocks; this depends on whether the government follows a high or low monetary growth rate rule and whether inflation or unemployment is the main concern of the electorate.     

AN EMPIRICAL CHARACTERIZATION OF THE DYNAMIC EFFECTS OF POLICE SPENDING ON VIOLENT AND PROPERTY CRIME

The study estimates the dynamic effects of shocks to police expenditures on measures of violent and property crime rates using annual U.S. state-level data for the period 1960–2015. We employ a structural panel VAR model and achieve identification by imposing the restriction that police spending responds to structural shocks to crime with at least a lag of 1 year. Results indicate that a shock to police spending leads to (a) persistent and significant decreases in violent and property crime rates and (b) significant and persistent negative impacts on crime rates in periods of high crime but little impacts in periods of low crime. Variance decompositions show that shocks to police spending account for moderate to large proportions of the variability of U.S. state-level crime rates. Our findings are robust across separate measures of violent and property crime rates, as well as to the inclusion of additional variables to the baseline panel VAR model. (JEL K42)
