BETWEEN SCYLLA AND CHARYBDIS: INCOME DISTRIBUTION,CONSUMER CREDIT,AND BUSINESS CYCLES

We introduce a macroeconomic model with heterogeneous households and an aggregate banking sector in order to analyze the impact of rising income inequality under different credit scenarios. Growing inequality produces debt‐led consumption boom dynamics when the banking sector is characterized by a lower capital requirement and a higher willingness to lend. Instead, when inequality rises but the banking sector is highly regulated, aggregate demand and output fall. Our results also yield new insights on the appropriate fiscal policy reaction to stabilize the economy: acting on the progressivity of the tax system seems more effective than a proactive countercyclical fiscal policy.

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)     

ASSET PRICE BUBBLES AND TECHNOLOGICAL INNOVATION

We introduce borrowing constraints into a two‐sector Schumpeterian growth model and examine the impact of asset price bubbles on innovation. In this environment, rational bubbles arise when the intermediate good producing R&D sector is faced with adverse productivity shocks. Importantly, these bubbles help alleviate credit constraints and facilitate innovation in the stagnant economy. On the policy front, we make a case for debt financed credit to the R&D sector. Further, we establish that a constant credit growth rule (akin to the Friedman rule) outperforms the often prescribed counter‐cyclical “lean against the wind” credit policy. (JEL E32, E44, O40)     

PRODUCT DIVERSITY,DEMAND STRUCTURES,AND OPTIMAL TAXATION

This article studies optimal taxation in a general equilibrium macroeconomic model with endogenous entry. We compare the constant elasticity of substitution (CES) model to three alternative demand structures: oligopolistic competition in prices, oligopolistic competition in quantities, and translog preferences. Our economy is characterized by two distortions: a labor distortion due to the misalignment of markups on goods and leisure, and an entry distortion due to the misalignment of the consumer surplus effect and the profit destruction effect of entry. The two distortions interact in determining the wedge between the market‐driven and optimal level of product diversity. We show how optimal labor and entry taxes depend on the prevailing demand structure, the nature and size of entry costs, and the degree of substitutability between goods. (JEL E22, E61, E62)     

RISK ASSESSMENT UNDER A NONLINEAR FISCAL POLICY RULE

In the aftermath of the recent debt crisis, many countries are implementing nonlinear fiscal policy rules, whereby the government's responsiveness to debt strengthens at higher levels of debt. This paper examines how a nonlinear fiscal policy rule affects the possibility of future insolvency in a small open economy. We find that (1) the criteria for a nonlinear fiscal rule to eliminate explosive behavior should be tighter than the ones proposed by Bohn (1998); (2) a country that adopts a nonlinear fiscal rule could substantially reduce the probability of a solvency crisis; and (3) a nonlinear fiscal rule allows a country to reduce the possibility of insolvency without large initial responsiveness.

POLITICAL BUSINESS CYCLES IN THE NEW KEYNESIAN MODEL

This paper tests various political business cycle theories in a New Keynesian model with a monetary and fiscal policy mix. All the policy coefficients, the target levels of inflation and the budget deficit, the firms' frequency of price setting, and the standard deviations of the structural shocks are allowed to depend on “political” regimes: a preelection versus postelection regime, a regime that depends on whether the president (or the Fed chairman) is a Democrat or a Republican, and a regime under which the president and the Fed chairman share party affiliation in preelection quarters or not. The results provide evidence that several coefficients are influenced by political variables. The best‐fitting specification, in fact, is one that allows coefficients to vary according to a regime that depends on whether the economy is in the few quarters before a presidential election or not. Monetary policy becomes considerably more inertial before elections and fiscal policy deviations from a simple rule are more common. There is some evidence that policies become more expansionary before elections, but this evidence disappears for monetary policy in the post‐1985 sample. (JEL C11, D72, E32, E52, E58, E63)     

THE EFFECTS OF ASSET PURCHASES AND NORMALIZATION OF U.S. MONETARY POLICY

This paper examines changes in the effects of unconventional monetary policies in the United States. To this end, we estimate a Markov-switching VAR model with absorbing regimes to capture possible structural changes. Our results detect regime changes around the beginning of 2011 and the middle of 2013. Before 2011, the U.S. large-scale asset purchases (LSAPs) had relatively large impacts on the real economy and prices, but after the middle of 2013, their effects were weaker and less-persistent. In addition, after the middle of 2013, which includes the monetary policy normalization period, the asset purchase (or balance sheet) shocks had slightly weaker effects than during the early stage of the LSAPs but stronger effects than during the late stage of the LSAPs, while interest rate shocks had insignificant effects on the real economy and prices. Finally, our results suggest that the positive responses of durables and capital goods expenditures to interest rate shocks weakened the negative impacts of interest rate hikes after the middle of 2013 including the period of monetary policy normalization.

TAX RATES,GOVERNANCE, AND THE INFORMAL ECONOMY IN HIGH‐INCOME COUNTRIES

Approximately 16.7% of output in high‐income OECD (Organisation for Economic Cooperation and Development) countries is produced informally. I present a model economy where entrepreneurs decide how much of their production to keep informal. Informality carries a risk of getting caught, taxed, and fined. Results from a model with differences in tax rates alone only agree to approximately 23% with data on informality. Taking into account both governance quality and tax rates, agreement between the model's results and data increases to 72%. A policy experiment raising governance quality in Greece, Italy, Spain, and Portugal to Finnish standards reduces informality by 13 percentage points. (JEL E26, H26, J24)     

AN OPEN‐ECONOMY MODEL WITH MONEY,ENDOGENOUS SEARCH,AND HETEROGENEOUS FIRMS

This paper describes a new monetary open‐economy model where firms have market power due to search frictions in the goods market, and endogenous search effort by consumers mitigates this market power. The optimal inflation rate generally depends positively on the cost of search effort, the cost of firm entry, and the cost of trade. Higher inflation always improves a country's terms‐of‐trade against its trading partners. I also characterize a general class of matching processes which offer a novel approach to modeling firm sales. (JEL D43, E40, F12)     

MONETARY POLICY AND ENDOWMENT RISK IN A LIMITED PARTICIPATION MODEL

A limited participation model is constructed to study the risk‐sharing role of monetary policy. A fraction of households exchange money for interest‐bearing government nominal bonds in the asset market and the government injects money through open market operations. In equilibrium, money is nonneutral and monetary policy redistributes consumption across households. Without idiosyncratic endowment risk, monetary policy becomes a perfect risk‐sharing tool, but with idiosyncratic endowment risk, it is not. The Friedman rule is not optimal in general. (JEL E4, E5)     

FINANCIAL CRISES,OUTPUT LOSSES,AND THE ROLE OF STRUCTURAL REFORMS

Financial crises take a heavy toll on output growth. We assess the role of structural reforms in reducing the output losses resulting from financial crises across advanced economies, emerging and developing economies, and low‐income developing economies. We also revisit the role of macroeconomic policies in this context. The impact of crises on output growth differs between types of crises and economies, thus warranting sample splits along these lines. Some but not all reforms and policies help to reduce the output losses of crises in the medium term, highlighting the need not to overgeneralize the effectiveness of reforms and policies. Further research is warranted to further explore the heterogeneity in the impact of financial crises on output growth and to better understand when and how specific structural reforms and macroeconomic policies can mitigate the output costs of financial crises.

ON ENDOGENOUS BUSINESS CYCLES UNDER INCREASING RETURNS TO VARIETY AND SECTOR‐SPECIFIC EXTERNALITY

We examine the theoretical as well as quantitative interrelations between endogenous business cycles, increasing returns to product variety and sector‐specific productive externalities within a two‐sector real business cycle model. In a calibrated version of our benchmark closed‐economy setting, the threshold level of investment externalities needed for equilibrium indeterminacy is found to be monotonically increasing in the degree of market competitiveness. We also study the model's local stability properties (i) when the parameters that govern the level of intermediate‐good producers' market power and the strength of variety effects are disentangled; and (ii) in the context of a small open economy. (JEL E30, E32, O41)     

CAPITAL CONTROLS,MONETARY POLICY,AND BALANCE SHEETS IN A SMALL OPEN ECONOMY

We develop a small open economy, New Keynesian model that incorporates a financial accelerator in combination with liability dollarization. Applying a Ramsey‐type analysis, we compare the welfare implications of an optimal monetary policy under flexible exchange rates and an optimal capital control policy under fixed exchange rates. In an economy without the financial accelerator, an optimal monetary policy under flexible exchange rates is superior to an optimal capital control policy under fixed exchange rates. In contrast, in an economy with the financial accelerator, an optimal capital control under fixed exchange rates yields higher welfare than an optimal monetary policy under flexible exchange rates.(JEL E44, E52, F32, F38, F41)     

DISINFLATION,INEQUALITY, AND WELFARE IN A TANK MODEL

We investigate the redistributive and welfare effects of disinflation in a two-agent New Keynesian model characterized by limited asset market participation and wealth inequality. We highlight two key mechanisms driving our long-run results: (1) the cash in advance constraint on firms working capital; (2) dividends endogeneity. These two channels point in opposite directions. Lower inflation softens the cash in advance constraint and, by raising labor demand, lowers inequality. But disinflation also raises dividends and this increases inequality. The disinflation is always welfare-improving for asset holders. We obtain ambiguous results for non-asset holders, who suffer substantial consumption losses during the transition.

CIVIL ASSET FORFEITURE,CRIME, AND POLICE INCENTIVES: EVIDENCE FROM THE COMPREHENSIVE CRIME CONTROL ACT OF 1984

The 1984 federal Comprehensive Crime Control Act (CCCA) included a provision that permitted local law enforcement agencies to acquire up to 80% of the proceeds derived from civil asset forfeitures obtained in joint operations with federal authorities. We investigate how this rule governing forfeited assets influenced crime and police incentives by taking advantage of pre‐existing differences in state‐level civil asset forfeiture law and the timing of the CCCA. We find that after the CCCA was enacted crime fell about 17% in places where the federal law allowed police to retain more of their seized assets than state law previously allowed.

REAL EXCHANGE RATE,MONETARY POLICY,AND THE U.S. ECONOMY: EVIDENCE FROM A FAVAR MODEL

This paper examines the effects of exchange rate depreciation to the U.S. economy in a factor‐augmented vector autoregression model using monthly data of 148 variables for the post–Bretton Woods period of 1973–2017. Exchange rate shock is identified to reflect exogenous disturbances to the foreign exchange market, and movements in exchange rate that are not accounted for by changes in the U.S. monetary policy. We find that depreciation is expansionary and inflationary to the broad U.S. economy, the current account improves over time conforming to the J‐curve theory, and monetary policy is leaning against the wind. (JEL E3, E5, F31, F32, F41)     

FORWARD GUIDANCE AND THE STATE OF THE ECONOMY

This paper analyzes forward guidance in a nonlinear model with a zero lower bound (ZLB) on the nominal interest rate. Forward guidance is modeled with news shocks to the monetary policy rule, which capture innovations in expectations from central bank communication about future policy rates. Whereas most studies use quasi‐linear models that disregard the expectational effects of hitting the ZLB, we show how the effectiveness of forward guidance nonlinearly depends on the state of the economy, the speed of the recovery, the degree of uncertainty, the policy shock size, and the forward guidance horizon when households account for the ZLB.

MINIMUM WAGES,IMPORT STATUS,AND FIRMS' INNOVATION: THEORY AND EVIDENCE FROM CHINA

This study explores the heterogeneous effects of minimum wage on innovation of different types of firms. We develop an open‐economy R&D‐based growth model and obtain the following result: raising the minimum wage reduces innovation of firms that use domestic inputs but increases innovation of firms that import foreign inputs. We test this result using city‐level data on minimum wages and firm‐level patent data in China. In accordance with our theory, we find that raising the minimum wage is associated with more innovation by importing firms and less by non‐importing firms. This result survives a battery of robustness checks. (JEL E24, F43, O31)     

STOCK RETURNS, ASYMMETRIC VOLATILITY, RISK AVERSION, AND BUSINESS CYCLE: SOME NEW EVIDENCE

We study how three interrelated phenomena—excess stock returns and risk relation, risk aversion, and asymmetric volatility movement—change over business cycles. Using an asymmetric generalized autoregressive conditional heteroskedasticity in mean model and a Markov switching model, we find that excess stock return increases and asymmetric volatility movement is weakened during boom periods. This suggests that investors become more risk-averse during boom periods (i.e., procyclical risk aversion), which we confirm using a calibration of a simple equilibrium model .

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)
