Equilibrium Dynamics in an Endogenous Growth Model of Money and Banking

We construct an analytically tractable endogenous growth model of money and banking where money provides "liquidity services" to facilitate transactions and banks convert non-reserve deposits into productive capital. We examine both the long- and short-run effects of changes in the money growth rate or the reserve requirement ratio. In response to a change in the required reserve ratio, the inflation rate and the growth rates of capital, real balances, and consumption need not adjust monotonically along the transition path. While the balanced growth equilibrium may be either a saddle or a source locally, the global dynamical system exhibits flip bifurcation.     

The integration of the offshore and domestic banking system

The thesis of this article is that offshore banks are branches of the major U.S., British, Swiss, German, Japanese, etc., banks situated in ‘monetary havens’ jurisdictions in which they are subject to minimal regulation, especially to requirements that they must hold non-interest bearing reserves against their deposits. Each bank determines the maximum interest rate to pay on offshore deposits as a function of the maximum interest rate on domestic deposits and the implicit tax on reserve requirements. The more rapid growth of offshore deposits than of domestic deposits during the last several decades reflects two factors — the implicit tax on domestic deposits has increased with the upward movement in interest rates and investor assessment of the risk associated with external deposits has decreased. The effective reserve requirement applicable to each bank is the weighted average of requirements applied to its domestic deposits and to its offshore deposits. Because offshore deposits have grown more rapidly than domestic deposits, the effective reserve requirement has decreased: the fractional reserve multiplier has increased. Because the growth of offshore deposits to domestic deposits appears highly variable, the effectiveness of monetary control has declined.     

Corporate Taxes and Securitization

Most banks pay corporate income taxes, but securitization vehicles do not. Our model shows that, when a bank faces strong loan demand but limited deposit market power, this tax asymmetry creates an incentive to sell loans despite less‐efficient screening and monitoring of sold loans. Moreover, loan‐selling increases as a bank's corporate income tax rate and capital requirement rise. Our empirical tests show that U.S. commercial banks sell more of their mortgages when they operate in states that impose higher corporate income taxes. A policy implication is that tax‐induced loan‐selling will rise if banks’ required equity capital increases.     

Incentives and financial crises: Microfounded macroprudential regulation

We provide a micro-based rationale for macroprudential capital regulation of financial intermediaries (banks) by developing a model in which bankers can privately undertake a costly effort and reduce the probability of adverse shocks to their asset holdings that force liquidation (deterioration risk). A decline in the fundamental risk of assets ameliorates funding conditions, boosting the banks’ ability to expand their balance sheets. In principle, a higher continuation value would improve incentives to put effort. However, the rise in asset demand and prices also increases the payoff in liquidation, eventually reducing the equilibrium optimal effort. Poor incentives impose socially inefficient liquidation and can be corrected through a regulatory capital requirement. We show that the requirement should be high when fundamental risk is low. Therefore, the model suggests a theoretical foundation for macroprudential regulation and the countercyclical capital buffer of Basel III.     

Taxation of Financial Assets in Developing Countries

In developing countries most of the financial assets are depositsat commercial banks. This article focuses on the implicit taxationof financial assets through seigniorage, reserve requirements,lending targets, and interest ceilings combined with inflation.The impact of taxation on financial deepening increases significantlywith the tax rate, as shown by cross-sectional and time seriesdata for selected countries in Sub-Saharan Africa and SoutheastAsia. The problem of measuring revenue is examined, and theefficiency cost of taxation is analyzed in a Harberger framework.Although taxes on financial assets have a low administrativecost, the excess burden caused by the misallocation of resourcesis probably a much higher fraction of revenues than that ofother taxes.     

Rediscounting private dollar debt and capital flight in Ecuador

This paper presents an analysis of the impact of structural change on capital flight when the structural change constrains the monetary authorities' ability to impose an inflation tax. Implications for the conduct of economic policy in open economies are drawn from the experience of Ecuador.     

Banking in a Matching Model of Money and Capital

We introduce banks in a model of money and capital with trading frictions. Banks offer demand deposit contracts and hold primary assets to maximize depositors’ utility. If banks’ operating costs are small, banks reallocate liquidity eliminating idle balances and improving the allocation. At moderate costs, idle balances are reduced but not eliminated. At larger costs, banks are redundant. A central bank policy of paying interest on bank reserves can reverse inflation's distortionary effects, and increase welfare, but only when costs are small. The threshold levels of banks’ costs increase with inflation, suggesting inflation and banks’ utilization are positively associated.     

Controlling capital? Legal restrictions and the asset composition of international financial flows

How effective are capital account restrictions? We provide new answers based on a novel panel data set of capital controls, disaggregated by asset class and by inflows/outflows, covering 74 countries during 1995–2005. We find the estimated effects of capital controls to vary markedly across the types of capital controls, both by asset categories, by the direction of flows, and across countries' income levels. In particular, both debt and equity controls can substantially reduce outflows, with little effect on capital inflows, but only high-income countries appear able to effectively impose debt (outflow) controls. The results imply that capital controls can affect both the volume and the composition of capital flows.

Monetary policy, taxes, and the business cycle

This paper analyzes the interaction of inflation with the tax code and its contribution to aggregate fluctuations. We find significant effects operating through the tax on realized nominal capital gains. A tax on nominal bond income magnifies these effects. Our innovation is to combine monetary policy shocks with non-indexed taxes in a model where the central bank implements policy using an interest rate rule. Monetary policy had important effects on the behavior of the business cycle before 1980 because policymakers did not exert effective control over inflation. Monetary policy reform around 1980 led to better control, and with more stable inflation, the effect of the interaction between monetary policy and the nominal capital gains tax has become negligible.     

Central Bank Digital Currency,Credit Supply,and Financial Stability

We examine the implications of central bank digital currency (CBDC) for credit supply and financial stability using a monetary general equilibrium model. The introduction of deposits in CBDC account decreases credit supply by banks, raising the nominal interest rate and lowering a bank's reserve-deposit ratio. This increases the likelihood of bank panic in which banks exhaust cash reserves. However, once the central bank can lend all the deposits in CBDC account to banks, an increase in the quantity of CBDC which does not require reserve holdings can enhance financial stability by increasing credit supply and lowering nominal interest rate.     

Profit taxes and financing constraints

Without financing frictions, profit taxes reduce investment by their effect on the user cost of capital. With financing constraints, investment becomes sensitive to cash-flow. In this situation, even small taxes impose first order welfare losses, and ACE and cash-flow tax systems are no longer neutral. When banks become active and provide monitoring services in addition to finance, an ACE tax yields larger investment and welfare than an equal yield cash-flow tax.     

Revenue maximizing inflation

A classic monetary policy result is that revenue maximization entails setting the inflation tax rate equal to the inverse of the interest semi-elasticity of the demand for money. The standard approach underlying “Cagan's rule” is partial equilibrium in nature, treating money demand as being given from outside the model and abstracting from the real effects of inflation. This paper reconsiders the question of the revenue maximizing inflation rate in a general equilibrium framework with a labor-leisure choice, where money is held because it reduces transactions costs. In this framework, the revenue maximizing inflation tax rate is lower than that implied by Cagan's rule.     

Does Germany Collect Revenue from Taxing the Normal Return to Capital?*

A widespread objection to the introduction of consumption tax systems claims that this would lead to high tax revenue losses. This paper investigates the revenue effects of a consumption tax reform in Germany. Our results suggest that the revenue losses would be surprisingly low. We find a maximum revenue loss of 1.6 per cent of annual GDP. In some years, we even find tax revenue gains. This implies that the current tax system collects little revenue from taxing the normal return to capital. Based on these results, we calculate a macroeconomic measure of the effective tax rate on capital income.     

Capital flows,exchange rate management and monetary policy

Capital inflows have brought substantial macro and financial benefits; at the same time, the size and nature of capital inflows have complicated macroeconomic management in recipient countries. Multiple concerns have produced multiple responses by countries to capital inflows. Countries have pursued a combination of policies – let the exchange rate appreciate, accumulate foreign exchange reserves, with or without sterilization, liberalize outflows, tighten monetary and fiscal policies and in a few cases impose capital controls on inflows either directly or through prudential regulation. Experience shows that there are no corner solutions and countries have to resort to a judicious mix of these policies depending on the prevailing circumstances.     

Political monetary cycles and a de facto ranking of central bank independence

Political monetary cycles are less likely to occur in countries with independent central banks. Independent central banks can withstand political pressure to stimulate the economy before elections or finance election-related increases in government spending. Based on this logic and supporting evidence, we construct a de facto ranking of central bank independence derived from the extent to which monetary policy varies with the electoral cycle. The ranking avoids well-known problems with existing measures of central bank independence and provides independent information about average inflation and inflation volatility differences across countries.     

A lost century in economics: Three theories of banking and the conclusive evidence

How do banks operate and where does the money supply come from? The financial crisis has heightened awareness that these questions have been unduly neglected by many researchers. During the past century, three different theories of banking were dominant at different times: (1) The currently prevalent financial intermediation theory of banking says that banks collect deposits and then lend these out, just like other non-bank financial intermediaries. (2) The older fractional reserve theory of banking says that each individual bank is a financial intermediary without the power to create money, but the banking system collectively is able to create money through the process of ‘multiple deposit expansion’ (the ‘money multiplier’). (3) The credit creation theory of banking, predominant a century ago, does not consider banks as financial intermediaries that gather deposits to lend out, but instead argues that each individual bank creates credit and money newly when granting a bank loan. The theories differ in their accounting treatment of bank lending as well as in their policy implications. Since according to the dominant financial intermediation theory banks are virtually identical with other non-bank financial intermediaries, they are not usually included in the economic models used in economics or by central bankers. Moreover, the theory of banks as intermediaries provides the rationale for capital adequacy-based bank regulation. Should this theory not be correct, currently prevailing economics modelling and policy-making would be without empirical foundation. Despite the importance of this question, so far only one empirical test of the three theories has been reported in learned journals. This paper presents a second empirical test, using an alternative methodology, which allows control for all other factors. The financial intermediation and the fractional reserve theories of banking are rejected by the evidence. This finding throws doubt on the rationale for regulating bank capital adequacy to avoid banking crises, as the case study of Credit Suisse during the crisis illustrates. The finding indicates that advice to encourage developing countries to borrow from abroad is misguided. The question is considered why the economics profession has failed over most of the past century to make any progress concerning knowledge of the monetary system, and why it instead moved ever further away from the truth as already recognised by the credit creation theory well over a century ago. The role of conflicts of interest and interested parties in shaping the current bank-free academic consensus is discussed. A number of avenues for needed further research are indicated.     

A Model of QE,Reserve Demand,and the Money Multiplier

Quantitative easing (QE) programs have driven unprecedented expansions in the supply of central bank reserves around the world over the past two decades, fundamentally changing the implementation of monetary policy. The collapse in money multipliers following QE episodes has often been interpreted as implying banks are happy to passively hold most of the reserves created by QE. This paper develops a simple microsimulation model of the banking sector that adapts the traditional money multiplier model and allows for bank reserve demand to be inferred from monetary aggregates. The model allows the use of unwanted reserves by banks to play out over time alongside QE purchases and incorporates both significantly higher reserve demand after 2008 and capital constraints. With these additions, the model explains the persistently lower money multipliers seen in the United States following QE, as well as the growth in commercial bank deposits. The model suggests the demand from banks for reserves has increased substantially since the introduction of QE but not to the point where banks are passively absorbing all newly created reserves.
