Asset price inflation and monetary policy

It is crucial that central banks and regulatory authorities be aware of effects of asset price inflation on the stability of the financial system. Lending activity based on asset collateral during the boom is hazardous to the health of lenders when the boom collapses. One way that authorities can curb the distortion of lenders' portfolios during asset price booms is to have in place capital requirements that increase with the growth of credit extensions collateralized by assets whose prices have escalated. If financial institutions avoid this pitfall, their soundness will not be impaired when assets backing loans fall in value. Rather than trying to gauge the effects of asset prices on core inflation, central banks may be better advised to be alert to the weakening of financial balance sheets in the aftermath of a fall in value of asset collateral backing loans.William S.

Deep habits and the dynamic effects of monetary policy shocks

We introduce deep habits into a sticky-price sticky-wage economy and examine the resulting models ability to account for the impact of monetary policy shocks. The deep habits mechanism gives rise to countercyclical markup movements even when prices are flexible and interacts with nominal rigidities in interesting ways. Key parameters are estimated using a limited information approach. The deep habits model can account very precisely for the persistent impact of monetary policy shocks on aggregate consumption and for both the price puzzle and inflation persistence. A key insight is that the deep habits mechanism and nominal rigidities are complementary: the deep habits model can account for the dynamic effects of monetary policy shock at low to moderate levels of nominal rigidities. The results are shown to be stable over time and not caused by monetary policy changes.     

China's monetary policy surprises and corporate real investment

We evaluate the effect of China's monetary policy shocks on corporate real investment. We propose a new approach to identify China's monetary policy shocks using high-frequency surprises based on treasury futures around monetary policy announcements as external instruments. We then estimate the dynamic effect of monetary policy shocks on corporate real investment using a rich firm-level data of all listed non-financial firms in China. We find that an unexpected monetary policy easing boosts firms' investment expenditures with heterogeneous dynamic responses across firms: small-sized firms have quicker responses than large-sized firms, especially for non-state-owned enterprises (non-SOEs). We show that sales revenue response could be the channel through which monetary policy shock transmits to non-SOEs' investment expenditures in China.     

Macroeconomic impact of monetary policy shocks: Evidence from recent experience in Thailand

This paper investigates the monetary transmission mechanism in Thailand, employing a VAR approach. It is found that the Bank of Thailand has leverage over the real interest rate in the short run due to inflation inertia. It is also found that the Thai monetary transmission mechanism has important international dimensions. More specifically, monetary contraction has stronger negative effects on import demand in the short run even though import prices fall.     

The role of oil price shocks on China's real exchange rate

This paper investigates to what extent the oil price shock and three other types of underlying macroeconomic shocks impact the trend movements of China's real exchange rate. By constructing a four-dimensional structural VAR model, the results suggest that real oil price shocks would lead to a minor appreciation of the long-term real exchange rate due to China's lesser dependence on imported oil than its trading partners included in the RMB basket peg regime and rigorous government energy regulations. The real shocks, as opposed to nominal shocks, are found to be dominant in the variations of the real exchange rate.     

Effects of foreign and domestic economic policy uncertainty shocks on South Korea

This paper investigates the effects of foreign and domestic economic policy uncertainty shocks on South Korea via structural VARs. The results show that both foreign and domestic policy uncertainty shocks exert negative and significant impacts on South Korea. Foreign economic policy uncertainty shocks are found to be more dominant than domestic economic policy uncertainty shocks in influencing the Korean output. The results also indicate that economic policy uncertainty that originates from foreign countries is a significant source of disturbance to the Korean economy, but domestic policy uncertainty plays a rather limited role in explaining Korean business fluctuations.     

News shocks and Japanese macroeconomic fluctuations

Are the changes in the future technology process, the so-called “news shocks,” the main contributors to the macroeconomic fluctuations in Japan over the past forty years? In this paper, we take two structural vector-auto-regression (SVAR) approaches to answer this question. First, we quantitatively evaluate the relative importance of news shocks among candidate shocks, estimating a structural vector-error–correction model (SVECM). Our estimated results suggest that the contribution of the TFP news shocks is nonnegligible, which is in line with the findings of previous works. Furthermore, we disentangle the source of news shocks by adopting several kinds of restrictions and find that news shocks on investment-specific technology (IST) also have an important effect. Second, to minimize the gap between the SVAR approach and the Bayesian estimation of a dynamic stochastic general equilibrium model, we adopt an alternative approach: SVAR with sign restrictions. The SVAR with sign restrictions reconfirms the results that the news shocks are important in explaining the Japanese macroeconomic fluctuations.     

Uncertainty and monetary policy

The experience of monetary policy making in an uncertain environmenthas encouraged increased attention to the concept of model uncertainty,that is, uncertainty as to which is the best model. A particulardifficulty has been the need to operationalise the concept inorder to yield definitive policy recommendations. If this typeof uncertainty is unquantifiable, then a policy rule determinedby a single model may not in fact be the best approach; pluralismof method and the exercise of judgement offer a potential solution.A rigorous foundation for such an approach is available in Keynes'sphilosophical analysis of decision making under uncertainty.It is concluded that more analytical attention needs to be devotedto agents’ own model uncertainty, and to judgement. Butultimately the scope for synthesis between the model uncertaintyand Keynes uncertainty approaches rests on whether or not thesubject matter is such that knowledge of it is best representedby one formal model.

Market discipline and monetary policy

The effects of forward looking expectations of future inflationon equilibrium inflation and interest rates are examined withinan imperfect information framework. Expectations of future inflationaffect equilibrium in a manner similar to an increase in thecentral bank's weight on future social welfare, making it morelikely an opportunistic central bank will actually deliver onits announced inflation targets, and output expansions can ariseeven if the central banker is revealed to be a low inflationtype. The model also illustrates the channels through whichinflation scares raise current real interest rates.     

Bank competition and monetary policy

There is an apparent theoretical discrepancy between the effects of monetary policy shocks on economies with differently competitive banking sectors. We employ cross-country data to investigate this hypothesis with two different approaches. First, using aggregate data we analyze the correlation between two indices: (i) a cumulative impulse response function providing an index of the effect of monetary policy shocks; and (ii) Panzar and Rosse's H-statistic as an index of the state of bank competition. Second, using disaggregated data we regress bank lending on the interaction of bank competition and monetary policy shocks. The first approach does not provide any evidence of a relationship between monetary policy shocks and bank competition. However, the second approach suggests that competition in the banking industry leads to smaller monetary policy effects on bank lending.     

Oil price shocks and Japanese macroeconomic developments

Using quarterly data for Japan over the period 1976:I–2008:II within a modelling strategy incorporating information about structural breaks in the variables included to represent the macroeconomic transmission channels, this paper shows that oil price shocks led to a fall in industrial production and higher inflation. However, these effects are only evident in the late 1970s and early 1980s. In more recent episodes of sharp oil price increases, inflationary effects are barely visible, and there is very limited evidence of oil‐induced industrial slowdowns.     

Rules,discretion, and international monetary and fiscal policy coordination

This paper considers the implications of international policy coordination when both monetary and fiscal policy choices are endogenous. We show that a movement from insular monetary commitment to international monetary policy coordination will, if fiscal policies are not coordinated, produce higher output and public expenditure levels at the expense of higher inflation rates. We also show that the concurrent coordination of monetary and fiscal policies raises output and inflation while lowering public expenditure relative to a regime of monetary coordination alone. We conclude that the arguments for concurrent monetary and fiscal policy coordination fail to have a clear-cut theoretical basis.     

The relationship between monetary policy and economic development in modern Europe: Problems and possible solutions

The author analyzes the risks of dismantling of the European Union posed by the current monetary policy, under which the single currency of the European Union not only retarded economic growth, but also led to economic contraction and high unemployment. Analyzing the widely debated idea of federalization as a way to tackle the challenge of Euroscepticism in major European countries and estimating the net transfers that are necessary for the proper functioning of the recipient country, the author concludes that federalization can only be considered a real action provided the current policy pursued by Germany as the hegemon of the European Union is to change. In the conclusion, the article reviews the problem of monetary independence as a necessary condition for the implementation of a national industrial policy based on the experience of France.     

Deflationary shocks and monetary rules: An open-economy scenario analysis

The paper considers the macroeconomic transmission of demand and supply shocks in an open economy under alternative assumptions on whether the zero interest floor (ZIF) is binding. It uses a two-country general-equilibrium simulation model calibrated to the Japanese economy vis-à-vis the rest of the world. Negative demand shocks have more prolonged and startling effects on the economy when the ZIF is binding than when it is not binding. Positive supply shocks can actually extend the period of time over which the ZIF may be expected to bind. More open economies hit the ZIF for a shorter period of time, and with less harmful effects. Deflationary supply shocks have different implications according to whether they are concentrated in the tradables rather than the nontradables sector. Price-level-path targeting rules are likely to provide better guidelines for monetary policy in a deflationary environment, and have desirable properties in normal times when the ZIF is not binding.

Deposit market deregulation,implicit deposit rates,and monetary policy

Conclusion Previous analyses of the economic effects of deposit market deregulation generally have treated the gradual elimination of deposit rate ceilings and the effective removal of barriers to bank competition for deposits as separate issues. The key implication of the analysis utilized in this paper is that there are important interactions between these two forms of deposit market deregulation and their ultimate effects on market behavior and outcomes. One aspect of this interaction concerns the payment of implicit interest on deposit balances. Although implicit interest payments usually are viewed as a response to the imposition of ceilings on explicit deposit rates, the amount of implicit interest paid by banks in fact depends crucially upon the amount of monopoly power available to banks as a result of entry restrictions. Competition in deposit markets drives the implicit interest rate to 0 even if the explicit deposit rate is regulated, and the existence of imperfect competition in deposit markets makes the payment of positive implicit deposit interest a theoretical possibility even if the explicit deposit rate ceiling is removed.At a macroeconomic level, increased bank competition enhances the monetary and interest rate impacts of gradual relaxations of a binding deposit rate ceiling. If a ceiling on the explicit deposit rate is present, increased bank rivalry for deposits resulting from deregulation reduces monetary control whether the Fed targets a market interest rate or a reserve aggregate. When there is no ceiling on the explicit deposit rate, increased bank competition has ambiguous implications for monetary policy.The present trend in regulatory policy is pushing the U.S. financial system toward an environment in which explicit deposit rates are flexible, market determined variables and interbank rivalry for deposit funds is much more competitive. The thoretical analysis of this paper indicates that the likely results of these simultaneous developments are the demise of implicit deposit interest (marginal cost pricing of transactions services) and potential complications for the c onduct of monetary policy under either a reserve-oriented operating procedure or a procedure in which the Fed targets a market interest rate. However, the directions and magnitudes of the net impacts of those forms of deregulation ultimately are empirical issues that cannot be fully resolved.via a theoretical analysis.An earlier version of this paper was circulated by the Federal Home Loan Bank Board's Office of Policy and Economic Research as Invited Research Working Paper No. 59.

Bank dependency on foreign funding and global liquidity shocks: The importance of US monetary policy for a developing country

We examine international spillover effects of US monetary policy on bank lending in Cambodia, using unique data about loan disbursements and the funding structures of Cambodian banks from 2013Q1 to 2019Q2. The banking sector in a developing country is likely dependent on foreign funding, while the dependency could be the source of vulnerability to international monetary and economic conditions. We empirically document that US monetary policy is likely to be transmitted to Cambodian bank lending through foreign funding. We also document that Cambodian banks change their risk-taking behavior in response to the spillover effects of US monetary policy. Furthermore, these results are robust for US monetary policy, but weak and not robust for the monetary policies of the Cambodian bank’s major shareholders’ home countries, suggesting that US monetary policy should be primarily taken into account in supervising banks that are reliant on foreign funding, in addition to domestic economic conditions.

Forward exchange,short term capital flows and monetary policy

Summary This paper re-examines the relationships between short term capital flows and monetary policy, in the light of a new theoretical approach of the forward exchange market. They contend that the traditional forward exchange market theory is a misleading one as it fails to give all the importance it deserves to the distinction between covered and uncovered exchange transactions and to the actual role of the arbitrageurs. As a consequence of this analysis, they demonstrate that the problem of monetary management in an open economy must be dealt with in a way different from what has been usual, and they conclude that monetary policy, central banks' intervention on the foreign exchange market and direct controls on capital movements can still have some efficiency in the struggle against inflation, either of the domestic or the imported type.
