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.

THE CYCLICAL BEHAVIOR OF PRICES AND RELATIVE PRICES

Price and output shock correlations provide information concerning macroeconomic shocks. Previous research generally finds small or negative correlations between real gross domestic product (GDP) and GDP deflator shocks but positive correlations between industrial production (IP) and consumer price index (CPI) shocks at short forecast horizons. We show that mismatched price and output correlations may have different magnitudes or signs than matched pairs. Matched and mismatched correlations between disaggregated prices and output from the GDP accounts indicate the procyclical price of nondurables to durables makes correlations between mismatches misleading. Thus, there is reason to be skeptical of results based on IP and the CPI. (JEL E31, E32)     

LIMITED ASSET MARKET PARTICIPATION AND THE EURO AREA CRISIS: AN EMPIRICAL DSGE MODEL

We estimate a medium‐scale dynamic stochastic general equilibrium model for the Euro area with limited asset market participation (LAMP). Our results suggest that in the recent European Monetary Union years LAMP is particularly sizable (39% during 1993–2012) and important to understand business cycle features. The Bayes factor and the forecasting performance show that the LAMP model is preferred to its representative household counterpart. In the representative agent model the risk premium shock is the main driver of output volatility in order to match consumption correlation with output. In the LAMP model this role is played by the investment‐specific shock, because non‐Ricardian households introduce a Keynesian multiplier effect and raise the correlation between consumption and investments. We also detect the contractionary role of monetary policy shocks during the post‐2007 years. In this period consumption of non‐Ricardian households fell dramatically, but this outcome might have been avoided by a more aggressive policy stance. (JEL C11, C13, C32, E21, E32, E37)     

CONSUMPTION EXTERNALITIES AND MONETARY POLICY WITH LIMITED ASSET MARKET PARTICIPATION

This article explores the interaction between consumption externalities and limited asset market participation (LAMP) in the standard New‐Keynesian model. We assess the performance of simple Taylor‐type interest rate rules with respect to (a) equilibrium determinacy, (b) the model's ability to simultaneously generate output and inflation volatility similar to the pre‐Volcker era, and (c) the model's response to a technology shock. We find that when individual preferences are affected by average household consumption (Aggregate Consumption Externality), stronger externalities increase the range of LAMP for which multiple equilibria arise even if the policy rule satisfies the Taylor principle. The interaction of LAMP and externalities can generate vast inflation/output relative volatility in line with the one observed in the data in the 1970s. According to our analysis, consumption externalities also affect the responses of endogenous variables to total factor productivity shocks. (JEL E4, E5)     

ACCOUNTING FOR THE CYCLICAL DYNAMICS OF INCOME SHARES

Over the business cycle, labor's share of output is negatively but weakly correlated with output, and it lags output by about four quarters. Profits' share is strongly pro‐cyclical. It neither leads nor lags output, and its volatility is about five times that of output. Those assumptions relate to the structure of aggregate technology and the degree of competition in factor markets. Despite much evidence in favor of time‐varying income shares, macroeconomics still lacks models that can account for their time series facts. This article constructs a model that can replicate those facts. We introduce costly entry of firms in a model with frictional labor markets and find a link between the ability of the model to replicate income shares' dynamics and the ability of the model to amplify and propagate shocks. That link is a weak correlation between the real interest rate and output, a fact in U.S. data but a feature that models of aggregate fluctuations have had difficulty achieving. (JEL E3, E25, J3, E24)     

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.

MEASURING THE WORLD NATURAL RATE OF INTEREST

This article makes the first attempt to estimate the time‐varying natural rate jointly with the output gap and trend potential output growth for the world as a whole using a simple unobserved components model broadly following the methodology developed by Laubach, T., and J. Williams (“Measuring the Natural Rate of Interest.” Review of Economics and Statistics, 85(4), 2003, 1063–1070). We find that the world natural rate has been trending down for the past few decades. Over a quarter of the variation in the natural rate is accounted for by the trend potential output growth rate. However, the relationship between the world natural interest rate and the world trend growth is modest and not statistically significant. (JEL E4, E52, E32, C32)     

HAS PRODUCTION MANAGEMENT IMPROVED SINCE 1984?

The growth rate of GDP stabilized around 1984, and improvements in production management have been cited as a possible cause. This article examines this rationale with two‐digit SIC manufacturing data. The empirical questions are whether there is evidence of structural change in industry output around 1984 and, if so, did output track demand more closely following the change? The results indicate that only two industries exhibited structural change in the 1982–86 period. There is evidence that output has tracked demand more closely in recent years, but this is because demand shocks have become less persistent. (JEL C15, D21, E22)     

A COMPETITIVE MODEL OF WORKER REPLACEMENT AND WAGE RIGIDITY

We adapt the models of Menzio and Moen (2010) and Snell and Thomas (2010) to consider a labor market in which firms can commit to wage contracts but cannot commit not to replace incumbent workers. Workers are risk averse, so that there exists an incentive for firms to smooth wages. Real wages respond in a highly nonlinear manner to shocks, exhibiting downward rigidity, and magnifying the response of unemployment to negative shocks. We also consider layoffs and show that for a range of shocks labor hoarding occurs while wages are cut. We argue these features are consistent with recent evidence. (JEL E32, J41)     

UNDERSTANDING THE MACROECONOMIC IMPACT OF ILLIQUIDITY SHOCKS IN THE UNITED STATES

In this paper, we empirically investigate the role of stock market illiquidity shocks, stemming from Amihud's illiquidity measure, in explaining U.S. macroeconomic fluctuations from 1973 to 2018. We find that the impact of illiquidity shocks on economic activity is substantial, and historical decomposition analysis shows that cumulative illiquidity shocks were an essential contributor to the prolonged economic slump of the Great Recession. Moreover, our identified illiquidity shocks represent a distinct source of macroeconomic instability. This suggests that illiquidity shocks, measured by the stock price impacts, may contain more information than other types of shocks in recent studies, such as financial shocks and uncertainty shocks.

THE SHIFTS IN LEAD-LAG PROPERTIES OF THE U.S. BUSINESS CYCLE

We document shifts in the lead-lag properties of the U.S. business cycle since the mid-1980s. Specifically, (1) the well-known inverted leading indicator property of real interest rates has completely vanished; (2) labor productivity switched from positively leading to negatively lagging output and labor inputs over the cycle; and (3) the unemployment rate shifted from lagging productivity negatively to leading positively. Many contemporary business cycle models produce counterfactual cross-correlations revealing that popular frictions and shocks provide an incomplete account of business cycle comovement. Determining the underlying sources of these shifts in the lead-lag properties and their consequences for macroeconomic forecasts is therefore a promising direction for future research.

CONSUMPTION,SENTIMENT, AND ECONOMIC NEWS

This paper investigates the influence of economic news on consumer sentiment, and examines whether “news shocks”—changes in coverage that would not be expected from incoming data on economic fundamentals—have aggregate effects. Using monthly U.S. data and a structural vector autoregression, I find that (1) sentiment is affected by news shocks; (2) after filtering out effects of news shocks, shocks to sentiment still have positive effects on consumer spending; and (3) news shocks influence both spending and unemployment in significant, though transitory ways. These results are consistent with other evidence of a role of nonfundamental factors in aggregate fluctuations. (JEL E21, E32, D12)     

IDENTIFYING THE ROLE OF RISK SHOCKS IN THE BUSINESS CYCLE USING STOCK PRICE DATA

I analyze the sources of U.S. business cycle fluctuations in an estimated Dynamic Stochastic General Equilibrium model with a rich set of nominal and real rigidities and various exogenous disturbances. The model includes a shock to the expected risk‐premium, which introduces a time‐varying wedge between the policy rate set by the central bank and the cost‐of‐capital of firms. In the aggregate data, most U.S. corporations finance their investment using internal funds, and stock prices reveal the opportunity cost of this type of financing. I therefore use corporate market value and dividend data in the Bayesian estimation of the model to identify risk shocks. Variance decomposition exercises show that these shocks account for a substantial part of the variation in the stock market, as well as the variation in output and investment, especially at short forecast horizons. The variation of these variables at longer forecast horizons are mainly captured by shocks to investment‐specific technological change. Historical decomposition points to the important role played by risk shocks in the run up of stock prices and output in the late 90s, and in the reversal of these variables in the early 2000s and during the recent recession.

A MONETARY BUSINESS CYCLE MODEL FOR INDIA

A New Keynesian monetary business cycle model is constructed to study why monetary transmission in India is weak. Our models feature banking and financial sector frictions as well as an informal sector. The predominant channel of monetary transmission is a credit channel. Our main finding is that base money shocks have a larger and more persistent effect on output than an interest rate shock, as in the data. The presence of an informal sector hinders monetary transmission. Contrary to the consensus view, financial repression in the form of a statutory liquidity ratio and administered interest rates, does not weaken monetary transmission.

SECTORAL COMPOSITION OF GOVERNMENT SPENDING AND MACROECONOMIC (IN)STABILITY

This article examines the quantitative interrelations between sectoral composition of public spending and equilibrium (in)determinacy in a two‐sector real business cycle model with positive productive externalities in investment. When government purchases of consumption and investment goods are set as constant fractions of their respective sectoral output, we show that the public‐consumption share plays no role in the model's local dynamics, and that a sufficiently high public‐investment share can stabilize the economy against endogenous belief‐driven cyclical fluctuations. When each type of government spending is postulated as a constant proportion of the economy's total output, we find that there exists a trade‐off between public consumption versus investment expenditures to yield saddle‐path stability and equilibrium uniqueness.

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)     

MONETARY NEUTRALITY UNDER EVOLUTIONARY DOMINANCE OF BOUNDED RATIONALITY

We provide evolutionary game‐theoretic microfoundations to a dynamic complete nominal adjustment in response to a monetary shock by introducing a novel analytical notion that we call boundedly rational inattentiveness. We investigate the behavior of the general price level in a context where a firm can either pay a cost (featuring a random component) to update its information set and establish the optimal price (Nash strategy) or freely use non‐updated information and establish a lagged optimal price (bounded rationality strategy). We devise evolutionary microdynamics (with and without mutation) that, by interacting with the dynamics of the aggregate variables, determines the coevolution of the frequency distribution of information‐updating strategies in the population of firms and the extent of the nominal adjustment of the general price level to a monetary shock. As it turns out, evolutionary learning dynamics take the information‐updating process to a long‐run equilibrium configuration in which, albeit either most or even all firms play the bounded rationality strategy, the general price level is the symmetric Nash equilibrium price and the monetary shocks have persistent, although not permanent, impacts on real output. (JEL E31, C73, D83)     

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)     

SIGNAL EXTRACTION AND RATIONAL INATTENTION

In this paper we examine the implications of two theories of informational frictions, signal extraction (SE) and rational inattention (RI), for optimal decisions and economic dynamics within the linear‐quadratic‐Gaussian (LQG) setting. We first show that if the variance of the noise and channel capacity (or marginal information cost) is fixed exogenously in the SE and RI problems, respectively, the two environments lead to different policy and equilibrium asset pricing implications. Second, we find that if the signal‐to‐noise ratio and capacity in the SE and RI problems are fixed, respectively, the two theories generate the same policy implications in the univariate case, but different policy implications in the multivariate case. We also show that our results do not depend on the presence of correlation between fundamental and noise shocks. We then discuss the applications to macroeconomic models of permanent income and price‐setting. (JEL C61, D81, E21)     

LEANING AGAINST WINDY BANK LENDING

Using an estimated dynamic stochastic general equilibrium model with banking, this paper first provides evidence that monetary policy reacted to bank loan growth in the United States during the Great Moderation. It then shows that the optimized simple interest‐rate rule features no response to the growth of bank credit. However, the welfare loss associated to the empirical responsiveness is small. The sources of business cycle fluctuations are crucial in determining whether a “leaning‐against‐the‐wind” policy is optimal or not. In fact, the predominant role of supply shocks in the model gives rise to a trade‐off between inflation and financial stabilization. (JEL E32, E44, E52)
