US inflation dynamics on long-range data

In this article, we evaluate inflation persistence in the United States using long-range monthly and annual data. The importance of inflation persistence is crucial to policy authorities and market participants, since the level of inflation persistence provides an indication on the susceptibility of the economy to exogenous shocks. Departing from classic econometric approaches found in the relevant literature, we evaluate inflation persistence through the nonparametric Hurst exponent within both a global and a rolling window framework. Moreover, we expand our analysis to detect the potential existence of chaos in the data generating process, in order to enhance the robustness of our conclusions. Overall, we find that inflation persistence is high from 1775 to 2013 for the annual data-set and from February 1876 to May 2014 in monthly frequency, respectively. Especially from the monthly data-set, the rolling window approach allows us to derive that inflation persistence has reached to historically high levels in the post–Bretton Woods period and remained there ever since.

Working capital requirement and the unemployment volatility puzzle

Shimer (2005) argues that a search and matching model of the labor market in which wage is determined by Nash bargaining cannot generate the observed volatility in unemployment and vacancy in response to reasonable labor productivity shocks. This paper examines how incorporating monopolistically competitive firms with a working capital requirement (in which firms borrow funds to pay their wage bills) improves the ability of the search models to match the empirical fluctuations in unemployment and vacancy without resorting to an alternative wage setting mechanism. The monetary authority follows an interest rate rule in the model. A positive labor productivity shock lowers the real marginal cost of production and lowers inflation. In response to the fall in price level, the monetary authority reduces the nominal interest rate. A lower interest rate reduces the cost of financing and partially offsets the increase in labor cost from a higher productivity. A reduced labor cost implies the firms retain a greater portion of the gain from a productivity shock, which gives them a greater incentive to create vacancies. Simulations show that a working capital requirement does indeed improve the ability of the search models to generate fluctuations in key labor market variables to better match the U.S. data.     

SECTORAL PRODUCTIVITY GROWTH AND PRICE-MARGINAL COST MARGINS IN THE INTERMEDIATE GOODS MARKET

Models of aggregate productivity growth linked to sectoral models of production typically assume that all intermediate goods markets are perfectly competitive. An econometric analysis reveals that many intermediate goods markets exhibit transactions at prices quite different than marginal cost. Measures of productivity growth that ignore these market imperfections are biased. A measure of the actual magnitude of the bias that emerges under the assumption of equating price to marginal cost is constructed.     

INFLATION AND THE DISPERSION OF REAL WAGES*

The article studies the effects of inflation on real wage dispersion in a search‐monetary framework. The economy is characterized by frictions in both the goods and the labor markets. In the goods market, buyers and sellers bargain over prices, whereas in the labor market firms post wage offers. In equilibrium, a lower inflation rate increases the dispersion of real wages. This result is consistent with both the observed trends in wage dispersion and the inflation rate witnessed in the 1980s and the 1990s in the United States and the empirical literature linking reduced inflation to greater wage dispersion.     

ARE WAGE INCREASES IN CHINESE STATE INDUSTRY EFFICIENT? PRODUCTIVITY IN NANJING'S MACHINE-BUILDING INDUSTRY

Since China's economic reform began, wages in state enterprises have increased at rates much faster than the rate of price inflation. This paper investigates the source of this rapid wage increase for a sample of Chinese state-owned machine-building enterprises to determine whether increased wages can be best explained by changes in productivity, changes in the output market, or changes in input markets. CES production function estimates find the marginal product of labor was stagnant between 1980 and 1992 but initially higher than wages. Rising wages were therefore consistent with other evidence that the reform process cost the state sector its labor monopsony. ( JEL P31)     

A model of relative national price levels under pricing to market

This paper proposes an alternative to the Balassa-Samuelson theory of how relative price levels between countries are determined. The theory is a general equilibrium formulation of a model where pricing to market arises endogenously from firm decisions. It differs from Balassa-Samuelson in that it centers on the distinction between segmented national goods markets rather than the distinction between traded and nontraded goods. The paper also explores how Balassa-Samuelson might be updated by combining it together with pricing to market elements. Applied to the case of a monetary union, the theory offers an alternative explanation for the inflation differentials observed in EMU. It implies that such differentials may be a natural and enduring feature of a monetary union in which markets for goods and labor are less than fully integrated.     

A PANIC analysis on regional and sectoral inflation: the Spanish case

This article studies the stochastic properties of several inflation rates for the Spanish economy using the consumer price index (CPI) for the 17 regions and 12 groups of goods and services, and the producer price index (PPI) for 26 industrial sectors. To this end, we employ the panel analysis of nonstationarity in idiosyncratic and common components (PANIC) approach proposed by Bai and Ng (2004, 2010). This methodology enables us to decompose the observed inflation rate series into a common and an idiosyncratic component, thus allowing us to identify the exact source of nonstationarity. Our analysis provides strong evidence of the presence of a common stochastic trend driving the observed series forming the panel of CPI-based inflation rates for the regions. This, coupled with the presence of a jointly stationary idiosyncratic component, implies the existence of pairwise cointegration across the regional CPI-based inflation rates, which show a clear pattern of convergence over time. This gives an indication of increased geographical homogeneity in consumption patterns. The evidence for the panels of CPI-based inflation of groups of goods and services and PPI-based inflation of industrial sectors indicates the existence of four independent common stochastic trends. This, combined with jointly stationary idiosyncratic series, provides much weaker evidence of cross-cointegration for these two panels.     

Sticky prices and moderate inflation

Recent evidence shows that there is great heterogeneity in the price setting frequency across sectors, and that those changing prices frequently do so even under low inflation. What happens to price setting strategies of sticky price goods under moderate inflation? We built a dataset of monthly newspaper and magazine prices for Colombia, for the period 1960–2005, an exceptional example of prolonged moderate inflation. Within this macroeconomic scenario, and the novel database, we study the frequency of price adjustment, the relative importance of time- and state-dependent theories, and their evolution as inflation declined from moderate rates to single digits.     

Productivity Trends and the Sterling Real Exchange Rates*

This paper provides favorable econometric evidence for a productivity‐based model of the pound/euro real exchange rate. We find that a 1% increase in UK productivity is consistent with a 3.5% real depreciation of sterling. Likewise, a 1% increase in euro area productivity is compatible with a 5.16% real appreciation of sterling. The asymmetric response of UK and foreign productivity shocks corresponds well with our model if UK labor supply is more elastic than euro area labor supply. Estimates of equilibrium exchange rates suggest that sterling was not overvalued at its 2004Q3 level vis‐à‐vis the euro.     

Optimal long-run inflation with occasionally binding financial constraints

This paper studies the optimal long-run inflation rate in a simple New Keynesian model with occasionally binding collateral constraints that intermediate-good firms face on hiring labor. The paper finds that the optimal long-run annual inflation rate is around 1.5% if the economy is hit by a total factor productivity (TFP) shock and nearly 2.5% if the economy is subject to a markup shock. The shadow value of the collateral constraint is akin to an endogenous cost-push shock. Differently from usual cost-push shocks, however, this shock is asymmetric as it takes non-negative values only. Since the mean of this asymmetric endogenous cost-push shock is positive, inflation is also positive on average. In addition, a binding collateral constraint resembles a time-varying tax on labor, which the monetary authority can smooth by setting a positive inflation rate. More generally, the basic result is related to standard Ramsey theory in that optimal policy smoothes distortions over time.     

Nonlinear Adjustment in Law of One Price Deviations and Physical Characteristics of Goods

At a level of individual goods, heterogeneity of marginal transaction costs, proxied by price-to-weight ratios and stowage factors, explains a large part of the variation in thresholds of no-adjustment and conditional half-lives of law of one price deviations. Prices of heavier (more voluminous) goods deviate further before becoming mean-reverting. Moreover, after becoming mean-reverting, prices of heavier goods converge more slowly. Together with measures of pricing power, market size, distance, and exchange rate volatility, these factors explain up to 43% of variation in no-adjustment threshold estimates across 52 goods in US–Canada post-Bretton Woods monthly CPI data and are robust in a broader five-country dataset. They open two avenues for the importance of marginal transaction costs in accounting for real exchange rate persistence: through (a) generating persistence in individual real exchange rate components, and (b) accentuating it by the aggregation of heterogeneous components ("aggregation bias" of Imbs et al., 2005a ).     

What Determines Real Exchange Rates? The Nordic Countries

The model derived in this paper yields testable implications concerning the long‐run co‐movements of real exchange rates, relative labor productivity, the trade balance and terms of trade. Countries with relatively higher output growth, trade deficits or improved terms of trade are found to have more appreciated real exchange rates, with the main channel of transmission working through the relative price of nontraded goods. Exogenous terms‐of‐trade shocks are found to be the most important determinant of long‐run movements in the real exchange rate for Denmark and Norway, while demand shocks account for most of the long‐run variance in the real exchange rate for Finland and Sweden.     

Productivity Trends in Europe: Implications for Real Exchange Rates, Real Interest Rates, and Inflation

The paper examines a long–run (neoclassical) framework in which differences in productivity growth across sectors and countries lead to inflation differentials. In a currency union, these inflation differentials imply cross–country differentials in real interest rates. The authors estimate the likely size of these differentials for European Union countries, discuss the potential costs of persistent inflation differentials, and comment on the conflicts they may cause within Economic and Monetary Union (EMU). The analytical framework is a variant of the Balassa–Samuelson "productivity hypotheisis," which relates sectoral productivity trends to trends in the relative price of home goods.     

Estimated annual and lifetime labor productivity in the United States, 2016: implications for economic evaluations

Abstract

Background: Human-capital based lifetime productivity estimates are frequently used in cost-of-illness (COI) analyses and, less commonly, in cost-effectiveness analyses (CEAs). Previous US estimates assumed that labor productivity and real earnings both grow by 1% per year.

Objectives: This study presents estimates of annual and lifetime productivity for 2016 using data from the American Community Survey, the American Time Use Survey, and the Current Population Survey, and with varying assumptions about real earnings growth.

Methods: The sum of market productivity (gross annual personal labor earnings adjusted for employer-paid benefits) and the imputed value of non-market time spent in household, caring, and volunteer services was estimated. The present value of lifetime productivity at various ages was calculated for synthetic cohorts using annual productivity estimates, life tables, discount rates, and assumptions about future earnings growth rates.

Results: Mean annual productivity was $57,324 for US adults in 2016, including $36,935 in market and $20,389 in non-market productivity. Lifetime productivity at birth, using a 3% discount rate, is roughly $1.5 million if earnings grow by 1% per year and $1.2 million if future earnings growth averages 0.5% per year.

Conclusions: Inclusion of avoidable productivity losses in societal-perspective CEAs of health interventions is recommended in new US cost-effectiveness guidelines. However, estimates vary depending on whether analysts choose to estimate total productivity or just market productivity, and on assumptions made about growth in future productivity and earnings.     

Wage forming mechanism in the market transitional process of China (1993–2005): Evidence from the provincial panel data

Using the panel data of 31 provinces during 1993–2005, this paper examines the factors that influence wage changes in China. During the process of the marketization, the linkage between wage and some factors such as inflation, productivity and unemployment rate has been strengthened. But there still exists large room for further development of labor market, as the relationship between the wage and productivity is not sufficiently strong, and the wage’s response to the unemployment is lagged. The wage forming mechanism in different regions also varies. The econometric results show that, contrary to some public perceptions, the eastern areas’ wage marketization is not satisfactory.      

Labor market search, sticky prices, and interest rate policies

What accounts for the significant real effects of monetary policy shocks? And what accounts for the persistent and hump shaped responses of output and inflation in response to such shocks? These questions are investigated in a model that incorporates labor market search, habit persistence, sticky prices, and policy inertia. While habit persistence and price stickiness are important for the hump shaped output response and the long, drawn out inflation response, respectively, labor market frictions increase the output response and reduce the inflation response relative to an otherwise similar model based on a Walrasian labor market. Significantly, policy inertia itself is found to be the most important factor in accounting for the magnitude of the output effects of policy shocks in the model.

COMPARATIVE ANALYSIS OF EXCHANGE RATE APPRECIATION AND AGGREGATE ECONOMIC ACTIVITY: THEORY AND EVIDENCE FROM MIDDLE EASTERN COUNTRIES

The paper examines the effects of exchange rate depreciation on real output and price in a sample of 11 developing countries in the Middle East. The theoretical model decomposes movements in the exchange rate into anticipated and unanticipated components. Unanticipated currency fluctuations determine aggregate demand through exports, imports, and the demand for domestic currency, and determine aggregate supply through the cost of imported intermediate goods. The evidence indicates that the supply channel attributed to anticipated exchange rate appreciation results in limited effects on output growth and price inflation. Consistent with theory's predictions, unanticipated appreciation of the exchange rate appears more significant with varying effects on output growth and price inflation across developing countries.     

Services,innovation and the new economy

Several distinctive stylized facts form the new economy, an information technology service sector organized in network forms of organization, an inflation rate below its fundamentals, an increase in stock market volatility, high rates of economic growth, but apart from a small information technology manufacturing sector low productivity rates. This paper presents a model where the innovation of new service varieties can explain all of these facts. First, productivity gains are no longer realized within but between firms, as the increase in variety increases value-added per employee. Whilst service innovators, such as the information technology manufacturers, get ever more productive, individual service firms will exhibit low productivity. It is this unmeasured sectoral productivity gain, which is the key element in understanding the intrinsic inertia in the price index. Finally, the paper shows that variety in the service sector enables service providers to realize rents, where fluctuations of these rents are the basis of more than proportional changes in the firms' stock market value.
