Liquidity risk, economic development, and the effects of monetary policy

Empirical evidence indicates that monetary policy is not super-neutral in many countries. In particular, in high inflation economies, inflation is negatively related to economic activity. By comparison, inflation may be positively correlated with output in low inflation countries. We present a neoclassical growth model with money in which the incidence of liquidity risk is inversely related to aggregate capital formation. Interestingly, there may be multiple monetary steady-states where the effects of monetary policy vary. In poor economies, the financial system is highly distorted and higher rates of money growth are associated with less capital formation. In contrast, in advanced economies, a Tobin effect is observed. Since inflation exacerbates distortions from a coordination failure in the low-capital steady-state, individuals become much more exposed to liquidity risk. Consequently, optimal monetary policy depends on the level of development.     

International capital flows,liquidity risk,and monetary policy

In recent years, there has been a large amount of lending coming from the public sector of many developing countries. At the same time, the financial sectors in many advanced countries have issued a large share of portfolio debt to other countries. What are the implications of these events for the global financial system and overall economic activity? Do they have an impact on the transmission channels of monetary policy across countries at different stages of economic development? We investigate these important issues using a micro-founded model of money and banking so that the effects of monetary policy across countries can be meaningfully studied. Notably, the increase in capital outflows to the advanced economy renders monetary policy in developing countries to be less effective, while the effects of monetary policy in advanced economies are more pronounced. Yet, our results indicate that it can indeed be optimal for lower income countries to lend to the advanced world. Importantly, we find that the optimal amount of lending to advanced countries critically depends on the degree of liquidity risk — if it is sufficiently high, then public sector lending to advanced economies is not warranted. Consequently, our results indicate that governments in developing countries should carefully consider how much capital they send abroad to foreign countries.     

Liquidity risk and financial competition: Implications for asset prices and monetary policy

This paper studies the implications of banking competition for capital markets and monetary policy. In particular, I develop a two-sector monetary growth model in which a group of agents is exposed to liquidity shocks and money is essential. Banks insure depositors against such risk and invest in the economy's assets. In this setting, I compare an economy with a perfectly competitive banking sector to an economy with a fully concentrated financial sector. Unlike previous work, banks can have market power in both deposits and capital markets. Compared to a perfectly competitive financial sector, I demonstrate that a monopolistic banking system can have substantial adverse consequences on capital formation, assets prices, and the degree of risk sharing. Furthermore, multiple steady-states can emerge and the economy becomes subject to poverty traps. More importantly, market power in financial markets may overturn the Tobin effect present under a perfectly competitive financial sector. This necessarily happens in economies with high degrees of liquidity risk and low levels of capital formation.     

The role of financial sector competition for monetary policy

Abstract In this paper, we examine the impact of competition in the banking industry on financial market activity. In particular, we explore this issue in a setting where banks simultaneously insure individuals against liquidity risk and offer loans to promote intertemporal consumption smoothing. In addition, spatial separation and private information generate a transactions role for money. Interestingly, we demonstrate that the industrial organization of the financial system bears significant implications for the effects of monetary policy. Under perfect competition, higher rates of money growth lead to lower interest rates and a higher volume of lending activity. In contrast, in a monopoly banking sector, money growth restricts the availability of funds and raises the cost of borrowing.     

Social status, human capital formation and super-neutrality in a two-sector monetary economy

In this paper, we study how social status affects the impact of monetary policy on the long-run growth rate in a two-sector monetary economy with human capital accumulation, and find that the super-neutrality of money, with regard to the growth rate of the economy depends on the formation of human capital. In an economy with Lucas-type human capital formation, money is super-neutral; however, for an economy in which both physical and human capital are used as inputs for human capital accumulation, the money growth rate will have a positive effect on the long-run economic growth rate. The existence, uniqueness and saddle-path stability of balanced-growth equilibrium are also examined.     

国际储备积累、实物与资产价格通胀及货币政策独立性

本文理论模型显示,国际储备积累引起的货币增发会导致实物和资产价格上涨,降低货币政策独立性。首先,尽管货币政策工具短期内可以通过冲销和抑制信贷等方法控制通胀,但只要顺差积累足够大,长期无法阻止通胀。其次,如果人们预期央行未来会让物价上升,即使物价当前仍被较好地控制,资产价格也可能出现大幅上涨。最后,在"不可能三角"中,即使放弃资本自由流动,也并不意味着就能同时拥有汇率稳定和独立货币政策。

Fiscal policy,macroeconomic performance and industry structure in a small open economy

We analyse how fiscal policy affects both the macroeconomy and the industry structure, using a multi-sector macroeconomic model of the Norwegian economy with an inflation targeting monetary policy. Our simulations show that the magnitude of the government spending and labour tax cut multipliers, whether monetary policy is active or passive, is comparable to what is found in the literature. A novel finding from our simulations is that the industry structure is substantially affected by an expansionary fiscal policy, as value added in the non-traded goods sector increases at the expense of value added in the traded goods sector. Moreover, expansionary fiscal policy reduces the mark-ups in the traded goods sector, while the mark-ups are roughly unchanged in the non-traded goods sector. The contraction of activity in the traded goods sector increases when monetary tightening accompanies the fiscal stimulus. Hence, we find that such a policy mix is likely to produce significant de-industrialization in a small open economy with inflation targeting.     

Inflation Dynamics in India: Relative Role of Structural and Monetary Factors

This paper examines the relative role of structural and monetary factors in the variation of inflation in India over the period 1996–1997:Q1 to 2013–2014:Q4. The paper finds that both the monetary factors and the output gap has significant role. The role of the output gap in inflation is found more prominent than the monetary factors like broad money growth, interest rate and change in exchange rate. The depreciation of exchange rate and broad money growth stimulates inflation where as the interest rate is identified as an anti-inflationary monetary instrument. In view of a comprehensive policy for price stability, it is imperative to know the role of sectoral output gap in inflation. The paper, therefore, enquires the relative role of the primary, secondary and tertiary sector output gap in inflation. Output gap of each of these three sectors provokes inflation where the contribution of tertiary sector output gap is found to be the maximum followed by the primary sector and the secondary sector output gap. The prominent role of the output gap and comparatively passive role of monetary factors does not necessarily imply a non-effective monetary policy but suggests that controlling inflation only through the monetary management may not be effective.

     

Capital Trading,Stock Trading,and the Inflation Tax on Equity

A market for used capital goods, or financial instruments that represent the ownership of the used capital goods, induces inflation taxes on wealth and on the nominal income flows that they provide. This paper explicitly introduces trading in either used capital goods or financial instruments into the standard stochastic growth model with money and production. These two monetary economies are equivalent. The value of the firm is equal to the firm's capital stock divided by inflation. The resulting asset-pricing conditions indicate that the effect of inflation on asset returns differs from the effects found in the literature by the addition of a significant wealth tax.

A K% MONEY GROWTH LEADERSHIP RULE IN AN INTERNATIONAL MONETARY POLICY GAME

This paper examines a version of the Friedman k% money growth rule in an open economy monetary policy game. Using the two-country model proposed by Canzoneri and Henderson (1991), we show that, in response to asymmetric aggregate demand shocks, the Pareto-efficient outcome can be achieved by a policy that we call a k% money growth leadership rule. Following that rule, one country, the leader, sets her money supply growth rate, and the follower sets her money supply growth rate so as to keep the sum of nominal money supply growth at k%. We show that this policy yields the same outcome as does cooperative equilibrium. We also show that alternative policy rules, such as keeping exchange-rate adjusted money supply growth at k%, or forming a currency union, will not lead to the Pareto-efficient outcome in response to these demand shocks.

NOMINAL BONDS AND INTEREST RATES*

In this article, I integrate the microfoundation of monetary theory with the model of limited participation to analyze the competition between nominal bonds and money. The market for government nominal bonds is centralized and Walrasian, whereas the goods market is modeled as random matches. The government imposes a legal restriction that requires all government goods to be purchased with money but not with bonds. By contrast, private agents can exchange between themselves with both money and bonds. I show that an arbitrarily small legal restriction is sufficient to prevent matured bonds from being a medium of exchange. I also analyze the effects of monetary policy with and without the legal restriction. Some of those effects differ significantly from traditional monetary models.     

International Technology Diffusion and the Growth of TFP in the Manufacturing Sector of Developing Economies

This paper evaluates various channels through which foreign technology diffuses to the manufacturing sector of developing economies. These economies undertake virtually no own R&D, so they rely on foreign technology to a much larger extent than developed economies. We investigate the direct effect of foreign R&D, as well as technology embodied in imports of intermediate and capital goods and foreign direct investment, on the growth of total factor productivity and value added in the manufacturing sector of 32 economies during 1965–92. We find that foreign R&D typically has the biggest positive impact on domestic productivity and value‐added growth. Imports of capital goods and foreign direct investment also play a similar role, but their effect is of smaller magnitude and is not always significant.     

Capital Mobility, Consumption Substitutability and the Effects of Monetary Policy in Open Economies

Abstract. I use a dynamic general equilibrium two‐country optimizing model to analyze the implications of international capital mobility for the short‐run effects of monetary policy in an open economy. The model implies that the substitutability of goods produced in different countries plays a central role for the impact of changes in the degree of international capital mobility on the effects of monetary policy. Paralleling the results of the traditional Mundell–Fleming model, a higher degree of international capital mobility magnifies the short‐run output effects of monetary policy only if the Marshall–Lerner condition, which is linked to the cross‐country substitutability of goods, holds.     

GOVERNMENT DEFICITS IN POST-KEYNESIAN THEORIES OF GROWTH AND DISTRIBUTION

This paper examines the role of the government sector in post-Keynesiantheories of growth and distribution. It shows the possibilityof reconciling two views on income distribution, present inthe post-Keynesian tradition, which the literature has consideredalternative. By following Kaldor's suggestions on the role thatmonetary and fiscal policy can play in maintaining steady growthconditions, we find that distributive variables depend bothon the rate of growth of the economy, as pointed out by Kaldorand Pasinetti, and on the money rate of interest, as suggestedby Sraffa and by the subsequent elaborations of a monetary theoryof distribution. The paper first verifies the validity of thePasinetti theorem and the dual theorem, and shows that thesetheorems do not always hold when the government sector is explicitlyconsidered. It extends the analysis to the case of the corporateeconomy and institutional distribution, clarifying limits tothe neo-Pasinetti theorem related to the assumption of an endogenousvaluation ratio in steady-growth equilibrium and to the factthat this theorem does not hold when real capital investmentis also financed through the issue of firms' bonds.     

Money, banks and endogenous volatility

Summary. In this paper I consider a monetary growth model in which banks provide liquidity, and the government fixes a constant rate of money creation. There are two underlying assets in the economy, money and capital. Money is dominated in rate of return. In contrast to other papers with a larger set of government liabilities, I find a unique equilibrium when agents' risk aversion is moderate. However, indeterminacies and endogenous volatility can be observed when agents are relatively risk averse. Received: March 11, 1999; revised version: March 30, 1999     

Optimal Monetary Policy, Taxes, and Public Debt in an Intertemporal Equilibrium

This article is devoted to a study of the optimal monetary and fiscal policies within the framework of an overlapping generations model with cash-in-advance constraints. We first characterize the intertemporal equilibrium. Then we show how to decentralize the optimal growth path using available policy instruments (i.e., labor income and capital taxes, public debt, money supply). Between the four instruments: wages and capital taxes, debt and monetary policy, one is redundant among the three last which implies that the Friedman Rule is only a special case.     

Competition,taxation and economic growth

The paper mainly examines the relationship between economic growth, tax policy and sectoral labor distribution in an endogenous growth model with expanding varieties. For analyzing these relationships, we consider an economy where three sectors of production are vertically integrated: final goods sector, intermediate goods sector and research sector. We show that the extent of imperfect competition in the intermediate products market affects both economic growth and the allocation of the available labor to all the sectors employing this input. The resources from capital taxation, which are used for financing research sector, have a U-shaped effect on growth and lead to a movement of the labor from research sector to final goods sector. Additionally, we show that if there exists a higher competitive structure in an economy, the probability of the positive effect of an increase in tax on growth gets higher.     

我国企业投资对财政货币政策冲击反应的实证分析

本文运用结构向量自回归（SVAR）模型方法研究了我国企业投资对财政货币政策冲击的反应。通过采用1998年1月～2009年4月的月度数据实证研究表明：在经济周期的不同阶段,央行控制货币供给量的能力存在差异,导致货币政策执行效果不同。在经济繁荣阶段,社会资金运用效率较高,不存在剩余流动性,央行可以较容易地通过调整基础货币和货币乘数控制货币供给总量。这时货币供给的外生性较强,货币政策作用效果比较显著;而在经济衰退阶段,可选择的投资机会较少,流动性相对过剩,货币供给内生性增强,这时央行采取扩张性货币政策不能有效提高货币供给量,货币政策作用效果减弱。短期内虽然财政支出对企业投资会产生正向影响,但是负向影响要大于正向影响,也就是说财政政策对企业投资具有明显的挤出效应。
