DO CAPITAL ADEQUACY REQUIREMENTS MATTER FOR MONETARY POLICY?

Central bankers and financial supervisors can have conflicting goals. While monetary policymakers work to ensure sufficient lending activities as a foundation for high and stable economic growth, supervisors may limit banks’ lending capacities in order to prevent excessive risk taking. We show that, in theory, central bankers can avoid this potential conflict by adopting an interest rate strategy that takes accounts of capital adequacy requirements. Empirical evidence suggests that while policymakers at the Federal Reserve have adjusted their interest rate to neutralizing the procyclical impact of bank capital requirements, those in Germany and Japan have not.

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.

GROWTH OPPORTUNITIES,STRATEGIC SAVINGS,AND THE DOT‐COM BOOM AND BUST

Data from the dot‐com boom‐bust episode suggest that growth opportunities played an important role in explaining firms' financing strategy during this understudied episode. The low leverage of this sector was mainly driven by high growth firms which increased their leverage following the crash despite suffering a much larger fall in their market value. We present a parsimonious dynamic firm financing model where growth opportunities alone can generate the heterogeneous patterns in the financing and performance between high and low growth information technology firms prior to and following the market crash. The calibrated model also sheds light on the role played by monetary policy during that episode. (JEL G32, E22, E5)     

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.

MONETARY POLICY AND ANTI‐CYCLICAL BANK CAPITAL REGULATION

The financial crisis of 2008–2009 revived attention given to booms and busts in bank credit, and their effects on real activity. This interest sparked two different strands of research in macro. The first one focuses on monetary policy in the context of financial frictions. The second studies capital regulation in banking. To the best of our knowledge, so far these two topics have mostly been studied in isolation from each other. Thus, we still lack an understanding of how monetary policy and bank capital regulation interact in the presence of financial fragility. This paper aims to contribute to furthering this understanding. Specifically, we ask how the monetary policy rule should look like in the presence of cyclical capital requirements. We extend the dynamic stochastic general equilibrium model with bank capital in Aliaga‐Díaz and Olivero by introducing price rigidities in the spirit of the New‐Keynesian literature. We find that: First, anti‐cyclical requirements have important stabilization properties relative to the case of constant requirements. This is true for all types of fluctuations that we study, which include those caused by productivity, preference, fiscal, monetary, and financial shocks. Second, output and consumption volatilities present in the no regulation economy can be recovered with anti‐cyclical requirements as long as the policy rate responds only slightly to credit spreads. Third, monetary policy rules that respond to credit conditions also perform better in terms of welfare. (JEL E32, E44)     

OPTIMAL MONETARY POLICY AND IMPERFECT FINANCIAL MARKETS: A CASE FOR NEGATIVE NOMINAL INTEREST RATES?

This article studies optimal monetary policy in a model with credit frictions and money demand. We show that augmenting a standard New Keynesian model with money demand and financial frictions generates a mechanism that, in equilibrium, gives rise to optimal negative nominal interest rates. In addition, we find that the tighter credit markets are, the lower the optimal nominal policy interest rate and the more likely it is to be negative. Quantitatively, when credit constraints are binding, a standard calibration of the model generates an optimal nominal policy interest rate that is roughly ?4% annually.

ELASTIC CAPITAL SUPPLY AND THE EFFECTS OF FISCAL POLICY

Existing analyses of the effects of fiscal policy in general equilibrium models have typically been conducted under the assumption that the long-run supply of capital is perfectly elastic at a fixed rate of time preference. These analyses have shown that the long-run response of the capital stock to changes in fiscal policy is crucial to generating the potential for “multiplier” effects in these models. In this paper we ask, what are the implications of relaxing the assumption of perfectly elastic capital supply for the analysis of fiscal policy? We show that with less than perfectly elastic capital supply, the potential for multipliers is actually enhanced. (JEL E62, D90)     

Financial Leverage and Shareholder’s Required Returns: Evidence from South Africa Corporate Sector

Recent financial crisis which saw an increase in risk premium and shareholder’s required return around the world has been in part attributed to firms excessive debt leverage. This paper tests the impact of debt leverage on shareholder’s required return in South Africa. The paper specifies dynamic panel models and uses difference generalized method of moment (GMM) estimation technique. The results show that long term debt is positively related to shareholder’s required return. Similarly, total debt is positively related to shareholder’s required return. The results are robust to alternative model specification namely system GMM. Based on the findings, the study suggests that debt leverage is an important risk factor to be priced in equity valuation. The findings also suggest that the dynamic nature of firms’ capital structure decision should not be neglected. The paper contributes to capital structure research by testing Modigliani and Miller proposition two on listed firms in South Africa. Besides, it uses better estimation technique that controls for unobservable firm-specific effects and endogenous problem. In addition, two measures of leverage are used as independent variable compared to a single measure commonly found in the literature.     

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.

EXCHANGE RATE REGIMES AND FISCAL DISCIPLINE: THE ROLE OF CAPITAL CONTROLS

How do exchange rate regimes influence fiscal discipline? This important question has typically been addressed exploiting the classic dichotomy of fixed versus flexible exchange rate regimes assuming perfect capital mobility. However, the role of capital controls cannot be neglected, particularly in developing countries. This paper analyzes the effects of capital controls on fiscal performance by focusing on dual exchange rate regimes. In a model in which the fiscal policy is endogenously determined by a nonbenevolent fiscal authority, dual regimes induce politicians to have higher fiscal deficits than under fixed and flexible regimes operating under perfect capital mobility. The model also shows this effect increases as fiscal authorities become more impatient. Dynamic panel regressions confirm that dual regimes lead to higher fiscal deficits than fixed and flexible regimes operating under unified rates. Using a dummy for pre‐electoral year as an indicator of fiscal authorities' shortsightedness, we also confirm that dual exchange rate has a more adverse effect on fiscal deficits as the authorities become more impatient.

THE COLLAPSE AND RECOVERY OF THE CAPITAL SHARE IN EAST GERMANY AFTER 1989

After the 1990 unification, East Germany's capital income share plunged to 15.2% in 1991, then increased to 37.4% by 2015. To account for these large changes in the capital share, I model an economy that gains access to a higher productivity technology embodied in new plants. As existing low productivity plants decrease production, the capital share varies due to the nonconvex production technology: plants require a minimum amount of labor to produce output. Two policies—transfers and government‐mandated wage increases—have opposite effects on output growth, but contribute to lowering the capital share early in the transition. (JEL E20, E25, O11)     

REGIONAL HOUSE PRICE DYNAMICS AND VOTING BEHAVIOR IN THE FOMC

This paper examines the impact of house price gaps in Federal Reserve districts on the voting behavior in the Federal Open Market Committee (FOMC) from 1978 to 2010. Applying a random effects ordered probit model, we find that a higher regional house price gap significantly increases (decreases) the probability that this district's representative in the FOMC casts interest rate votes in favor of tighter (easier) monetary policy. In addition, our results suggest that Bank presidents react more sensitively to regional house price developments than Board members do. (JEL E31, E58, R31)     

A FINANCE APPROACH TO ESTIMATING CONSUMPTION PARAMETERS

This paper relates consumption economics more closely to an aggregate financial variable than in any previous research. We compile the net real rate of return on a synthetic mutual fund (SMF) encompassing all major classes of financial assets and residential real estate. Return on the SMF better represents the market return of financial portfolio theory than any measure in use today and we demonstrate its merit in an expected utility model to estimate consumption parameters, the coefficient of relative risk aversion (CRRA), and intertemporal elasticity of substitution (IES). The estimates are stable across varying time periods and alternative measures of consumption. (JEL E21, D91, G11, C13)     

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)     

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)     

THE CREDIT‐CHANNEL TRANSMISSION MECHANISM AND THE NONLINEAR GROWTH AND WELFARE EFFECTS OF INFLATION AND TAXES

With the credit‐channel effect driven by the central bank's open market operations, this paper's model easily gives rise to the nonlinear inflation‐growth nexus, which is evidenced by a number of cross‐country empirical studies. The threshold level of the inflation rate is found to be lower when tax rates are higher. The presence of the credit‐channel effect also provides the rationale for setting positive (and smaller than 1) tax rates on consumption, labor income, and capital income. The optimal tax rates rise as the inflation target declines. Under a fiscal policy rule where labor and capital income taxes move proportionally to each other, the optimal capital income tax rate could be higher than the optimal labor income tax rate. Under a sufficiently large central bank balance sheet, the credit‐channel effect will be so weak that inflation and all kinds of taxes are growth and welfare repressing. This provides a rationale for central banks that have implemented quantitative easing policies to shrink their balance sheets. (JEL E58, E62, O42)     

MONETARY POLICY SHOCKS,EXPECTATIONS, AND INFORMATION RIGIDITIES

This paper contributes to the literature by assessing expectation effects from monetary policy for G7 economies. We rely on expectation data from Consensus Economics and a panel vector autoregression framework, which accounts for international spillovers and time‐variation. We analyze whether monetary policy has changed the degree of information rigidity after the emergence of the subprime crisis and estimate effects of interest rate changes on expectations, disagreements, and forecast errors. We find strong evidence for information rigidities and identify higher forecast errors by professionals after monetary policy shocks. Our results suggest that the international transmission of monetary policy shocks introduces noisy information and partly increases disagreement among forecasters. (JEL E31, E52)     

Corporate Transformation to the Multilayered Subsidiary Form: Changing Economic Conditions and State Business Policy

Despite the prevalence of corporate change in the last decade, researchers have not examined whether a change occurred in the corporate form. The analysis here presents a historical case study of a large U.S. corporation and quantitative data on the largest 100 U.S. industrial corporations. The case study examines the effects of changing economic conditions and state business policy on the corporate form. This study demonstrates that the corporation changed to a multilayered subsidiary form (MLSF): a corporation with a hierarchy of two or more levels of subsidiary corporations with a parent company at the top of the hierarchy operating as a management company. Whereas rising debt and increasing competition in the 1970s and 1980s undermined corporations' capacity to accumulate capital, changes in state business policy in the mid-1980s provided the political-legal structure for corporations to restructure their assets as subsidiary corporations tax free. Changes in state business policy also provided a means for corporations to merge, acquire, and spin-off subsidiary corporations tax free. Quantitative data on the 100 largest U.S. industrial corporations show that while the multidivisional form decreased, the MLSF increased between 1981 and 1993. Findings support a capital dependence framework. The MLSF constructs liability firewalls among corporate entities and creates internal capital markets, reducing dependence on external capital markets.     

CAN MONETARY POLICY INFLUENCE LONG‐TERM INTEREST RATES? IT DEPENDS

Can monetary policy influence long‐term interest rates? Studies that have tackled this question using vector autoregressions (VARs) generally find that monetary policy's influence on long‐term interest rates is small and often statistically insignificant. Other studies, however, using a single‐equation approach, have found a robust relationship. Our study sheds new light on this question by estimating the effect of monetary policy shocks on long‐term interest rates in a VAR with long‐run monetary neutrality restrictions. We find that U.S. monetary policy can strongly influence long‐term interest rates, but only when the Federal Reserve has inflation‐fighting credibility and is able to firmly anchor inflationary expectations.

THE CYCLICALITY OF PRICE‐COST MARGINS IN BANKING: AN EMPIRICAL ANALYSIS OF ITS DETERMINANTS

We study the determinants of the cyclical behavior of banks' price‐cost margins in the United States banking sector, using time series quarterly data for the period 1979–2005. We contribute to the literature by building an empirical model of the countercyclical behavior of these margins first documented by Aliaga‐Díaz and Olivero (2010a) . Doing so we are able to explore potential explanations for this behavior, and to show that margins are consistently countercyclical, even after controlling for the effects of credit risk and monetary policy. As a mechanism for the propagation of aggregate shocks, the countercyclical nature of margins in banking can provide additional support to stabilization policy. (JEL E32, E44, G21)
