房价波动、调控政策立场估计及其影响效应研究--基于1998-2014年数据的实证分析

调控政策对房价的反应、立场和影响效应是政府政策设计的重要依据,2007年底金融危机爆发后,调控政策和房价波动都发生了显著变化。文章以2008年为界,构建了三个房价和政策变量的月度时间序列样本：1998-2007年、2008-2014年和1998-2014年,在此基础上,对2008年前后调控政策的反应、立场和影响效应进行了实证分析。结果表明：(1)实际贷款利率和货币供应量在2008年前后对目标变量的反应是交错变化的,货币供应量对房价的反应与假定相反,货币政策并未对房价做出充分反应,而财政和土地政策表现出了较好的反应结果。(2)货币供应量对房价波动的影响最大,是房价持续上涨的重要原因,2008年以来,固定资产投资的影响非常显著,脉冲响应分析发现利率只能在短期内对房价产生负向影响,除土地政策外,货币和财政政策皆会在长期内对房价产生稳定影响。文章的研究为推进房价政策调控和房地产市场健康稳定发展提供了可靠的经验支持。     

FISCAL POLICY AND ASSET PRICES

We analyse the impact of fiscal policy on asset prices using a panel vector auto‐regressive (PVAR) approach and quarterly data for ten industrialized countries. We find that positive fiscal shocks lead to a temporary fall in stock prices and a gradual and persistent decrease in housing prices. The empirical findings also point to: (i) a contractionary effect of fiscal policy on output in line with the existence of crowding‐out effects and the deterioration of credit conditions; (ii) a weakening of the effectiveness of fiscal policy in recent times; (iii) a more persistent response of asset prices for countries with a lower degree of openness; (iv) a larger impact of fiscal policy on asset prices for small countries; (v) a close link between the responsiveness of asset prices to fiscal policy and the government’s size; (vi) an increase of the sensitivity of asset prices to fiscal policy shocks following the process of financial deregulation and mortgage liberalization; and (vii) significant fiscal multiplier effects in the context of severe housing busts. Finally, the evidence suggests that changes in equity prices may help governments towards consolidation of public finances.     

Should monetary policy respond to asset price misalignments?

This paper analyses the relationship between monetary policy and asset prices using a structural rational expectations open economy model that allows for the effect of asset prices and exchange rates on aggregate demand. We assume that asset prices and exchange rates follow a partial adjustment mechanism whereas they are positively affected by past changes, thus allowing for ‘momentum trading’, while at the same time we allow for reversion towards fundamentals. We then conduct stochastic simulations using two alternative monetary policy rules, inflation-forecast targeting and the standard Taylor rule. The results indicate that, under both rules, interest rate setting that takes into account asset price misalignments leads to lower overall macroeconomic volatility, as measured by the postulated loss function of the central bank.     

Monetary policy and asset prices

The purpose of this paper is study the effect of monetary policy on asset prices. We study the properties of a monetary model in which a real asset is valued for its rate of return and for its liquidity. We show that money is essential if and only if real assets are scarce, in the precise sense that their supply is not sufficient to satisfy the demand for liquidity. Our model generates a clear connection between asset prices and monetary policy. When money grows at a higher rate, inflation is higher and the return on money decreases. In equilibrium, no arbitrage amounts to equating the real return of both objects. Therefore, the price of the asset increases in order to lower its real return. This negative relationship between inflation and asset returns is in the spirit of research in finance initiated in the early 1980s.     

我国资产价格波动与货币政策关系研究

随着金融自由化的逐步推进,资本市场存量日益增大.这既体现了金融深化程度的提高,又意味着货币供应与国民经济主要指标之间稳定性的弱化.资产价格对货币政策的制订和执行会产生深刻的影响.其中股价、房价等资产价格在货币政策传导机制中扮演的角色越来越重要.本文从实证角度出发,通过构建VAR模型检验我国资产价格对货币政策的反应以及资产价格对货币政策目标的影响,发现资产价格、货币政策及货币政策目标间存在长期协整关系,资产价格对产出有正向冲击作用,股市显著影响通货膨胀,但房地产市场对通货膨胀推动作用不明显,资产价格受货币政策的冲击影响显著,其中股市对货币政策冲击的反应明显大于房地产市场.     

What are the effects of fiscal policy on asset markets?

We investigate the link between fiscal policy shocks and asset markets. Our results show that spending shocks have: a positive and persistent effect on GDP in the U.S. and in the U.K., while for Germany and Italy, such impact is temporary; a positive and persistent effect on housing prices; a negative effect on stock prices; and mixed effects on the price level. A VAR counter-factual exercise suggests that fiscal shocks play a minor role in the asset markets of the U.S. and Germany, and substantially increase the variability of housing and stock prices in the U.K., while government revenue shocks have increased volatility in Italy.     

Structural VAR models for Malaysian monetary policy analysis during the pre- and post-1997 Asian crisis periods

This article conducts an in-depth investigation into building a Structural Vector Autoregression (SVAR) model and analysing the Malaysian monetary policy. Considerable attention is paid to: (i) the selection of foreign, policy and target variables; (ii) establish identifying restrictions and improve the estimates of impulse response functions; (iii) assess the importance of intermediate channels in transmitting monetary policy mechanism; and (iv) the way in which the 1997 Asian financial crisis affected the working of monetary policy. Malaysia is an interesting small open economy to study because, following this crisis, the government imposed capital and exchange rate control measures. The overall results suggest that the crisis and the subsequent major shift in the exchange rate regime have significantly affected the Malaysian ‘Black Box’. In the pre-crisis period, domestic variables appear to be more vulnerable to foreign monetary shocks. Further, the exchange rate played a significant role in transmitting the interest rate shocks, whereas credit and asset prices helped to propagate the money shock. In the post-crisis period however, asset prices play a more domineering role in intensifying the effects of both interest rate and money shocks on output, and the economy was insulated from foreign shocks.     

Money Quantity and Optimal Monetary and Fiscal Policy: A Quantitative Analysis

This paper quantitatively analyzes the impact of money stock on optimal monetary and fiscal policy in a stochastic production economy with sticky prices. The numerical results indicate that a sufficient large quantity of money makes a noticeable difference in many aspects of optimal monetary and fiscal policy. They suggest that the volatile inflation in China may not be as bad as the existing theory would have implied if its large amount of money is taken into consideration.     

Global financial crisis as a phenomenon of stock market overshooting

Inspired by Dornbusch’s model of exchange rate overshooting we develop a theory of stock market behaviour and its impact on the real economy. The idea is that stock market prices overshoot and undershoot their long-run equilibrium values which are determined by the development in the real economy. The overshooting is triggered primarily by a loose monetary policy. With our model we explain the genesis of the global financial crisis (GFC) 2008/2009 primarily as the result of a loose monetary policy in the USA. Following the overshooting and crash in the stock market the real economy dropped into a recession. After modelling the interaction of three markets with different speed of adjustment—money, stocks and goods—for a closed economy we expand it to an open economy and lastly study the spillovers of a financial market crisis between countries (from a large to a small country) by introducing the transmission channels of external trade or cross-border financial transactions. A long-lasting monetary easing as exhibiting by the Fed and the ECB since 2007 and 2008, respectively could—according to our model—generate another boom-bust cycle.

Stock prices and long-run demand for money: evidence from Malaysia

This paper investigates the money demand function for Malaysia in the 1971-1996 period using the multivariate cointegration and error correction model methodology. The results suggest that a stable long-run relationship exist between real M2, the interest rate differential, income and stock prices. Stock prices have a significant negative substitute effect on long-run as well as short-run broad-money demand (M2) and its omission can lead to serious misspecification in the money demand function. The analysis from the vector error correction model (VECM) and the Toda & Yamamoto (1995) causality tests find that money is endogenous and that there is at least a unidirectional relationship between stock prices and real M2. Stock prices Granger cause real M2 indirectly through income between interest rates and stock prices and stock prices and money stock. This paper comes to the conclusion that due to the endogeneity of money, M2 cannot be completely controlled by Malaysia's central bank. Therefore, in formulating future monetary policy, the response of money demand to stock prices should be considered.     

The London Business School econometric model of the UK

This paper describes the London Business School econometric model — the first fully computerized model of the UK — which has been used for regular public forecasting since 1966. The model, estimated on quarterly data, is organized around the income expenditure accounts with a fully integrated flow of funds sector which ensures consistency between portfolio decisions and income, savings and investment decisions. Aggregate demand is built up from its individual components so that demand influences are important for the short- and medium-term behaviour of the model. But there are important supply-side effects which work through the real exchange rate and real wages. Monetary conditions have a powerfull effect on the model through the exchange rate, personal sector wealth and interest rates. Wages and employment are determined in a labour market in which employment decisions depend on the level of demand and real wages while real wages depend on the level of unemployment, real benefits and direct and indirect taxes as well as underlying trends in productivity. Asset prices move in any period to clear both the spot and the future market in assets so that current asset prices in the equity, gilt-edged and foreign exchange markets reflect all current information about the expected state of the economy. In contrast, goods prices adjust sluggishly. The combination of continuously clearing asset markets and sluggish wages and prices gives the model many of the theoretical characteristics associated with the open-economy models of Dornbusch and Buiter and Miller.     

The importance of composition of fiscal policy: evidence from different exchange rate regimes

We study the macroeconomic effects of fiscal policies in an open economy. We emphasize two transmission mechanisms: the cost channel, by which wage government spending and labor taxes raise the real wage firms must pay, and the exchange rate channel, by which the nominal exchange rate shifts induced by fiscal policy have real effects if (some) prices and wages are sticky. The latter channel implies that changes in wage government spending or in labor taxation should have different effects under flexible than under fixed exchange rates. In a 1964–93 panel of OECD countries we find significant evidence for both channels. Moreover, we find that the real product wage and profitability are more responsive than quantities (employment and output) to fiscal policy innovations.     

Central bank instruments, fiscal policy regimes, and the requirements for equilibrium determinacy

This paper examines the role of the monetary instrument choice for local equilibrium determinacy under sticky prices and different fiscal policy regimes. Corresponding to Benhabib et al.'s results for interest rate feedback rules [Benhabib, J., Schmitt-Grohé, S., Uribe, M., 2001. Monetary policy and multiple equilibria. American Economic Review 91, 167–185], the money growth rate should not rise by more than one for one with inflation when the primary surplus is raised with public debt. Under an exogenous primary surplus, money supply should be accommodating—such that real balances grow with inflation—to ensure local equilibrium determinacy. When the central bank links the supply of money to government bonds by controlling the bond-to-money ratio, an inflation stabilizing policy can be implemented for both fiscal policy regimes. Local determinacy is then ensured when the bond-to-money ratio is not extremely sensitive to inflation, or when interest payments on public debt are entirely tax financed, i.e., the budget is balanced.     

Trade prices and supply in the UK economy

Current account imbalances are a major source of instability in the world monetary and trading system. Measures to correct these imbalances have largely involved adjustments to exchange rates. In the international trade literature, when the current account is in deficit, the Marshall-Lerner condition is sufficient for a successful devaluation. However, this partial equilibrium condition — apart from being based on the assumption that supply elasticities are infinite — abstracts from how the domestic economy responds to the change in relative prices. In this paper we develop a model of price and output determination in an open economy with imperpectly competitive markets, and draw a distinction between goods which are exported and those which are supplied to the domestic market. This means that we have to determine jointly both export prices and the domestic price of house sales. We show that as long as there is no money illusion in the labour market a fall in the nominal exchange rate raises domestic and export prices proportionally and leaves trade volumes unaffected. However, shifts in domestic absorption relative to overseas demand — by changing relative prices — cause shifts in the relative supply of exports and domestically sold goods and affect the trade balance. Thus fiscal and monetary measures directed towards reducing domestic absorption are more likely to be successful in correcting current account imbalances than exchange rate depreciation.     

Asset prices and expected monetary policy: evidence from daily data

This article explores the relationships among Libor, gold prices, the exchange rate, oil prices, fed funds futures prices and stock prices at a daily frequency. This article examines whether expected monetary policy, measured by changes in the prices of fed funds futures contracts, reacts to high frequency changes in asset prices and, in turn, whether asset prices respond to changes in expected monetary policy. The article reveals that there are statistically significant relationships between expected US monetary policy and shocks to Libor and exchange rates. It also reveals that there is no evidence of a systematic relationship between stock prices and expected monetary policy changes. Splitting the data into expansionary and recessionary periods using NBER dating, we find results for the expansionary periods that are very similar to the results for the entire period. For the periods of recession, we find little evidence of significant linkages between markets.     

Monetary policy and exchange rate dynamics in the Spanish economy

As the Spanish economy gets more integrated in international markets, the real exchange rate becomes a key determinant of the monetary transmission. In this paper we trace out the dynamic response of prices, output and the exchange rate following a monetary policy shock. We estimate a structural VAR model whose identification scheme is based on the long run properties common to a large class of models. The results suggest that a small model with efficient asset markets plus nominal inertia and long run monetary neutrality, captures the essential features of the monetary transmission mechanism in Spain. The interest rate shock is well identified and the exchange rate overshoots its long run value. There are no signs of liquidity puzzle nor of price puzzle or exchange rate puzzle either.     

影子银行规模变动的金融资产价格效应*

本文基于所构建的TVP VAR模型，检验了我国影子银行规模变动对金融资产价格的溢出效应。研究结果发现，影子银行规模的增加对商业银行同业拆放利率、房地产价格、股票市场价格指数和人民币实际有效汇率指数具有正向冲击。宏观经济政策调整使经济系统结构发生改变，从而导致金融资产价格对影子银行规模变动的冲击响应具有时变性。由于信息传导需要时间，因此影子银行规模变动的溢出效应具有时滞性。因此，应规范与引导影子银行的发展，在发挥其配置金融资源功能的同时提高资源配置效率，促进实体经济健康发展。     

Does money have a role in the inflation process? Evidence from Australia

Inflation, defined as a sustained increase in the price level, is considered a monetary phenomenon, as it can be explained within the framework of money‐demand and money‐supply relationships. In the extant literature, money growth is shown to remain causally related to inflation across countries and over time, irrespective of the exchange rate regime and stability of the money‐demand function. Nevertheless, emerging literature suggests a diminishing role of money in the conduct of monetary policy for price stability, especially under inflation targeting. Monetary policy in Australia under inflation targeting since 1993 is an example of policy that denies a relationship between money growth and inflation. The proposition that money does not matter insofar as inflation is concerned seems odd in both theory and the best‐practice monetary policy for price stability. This paper uses annual data for the period 1970–2017 and quarterly data for the period 1970Q1–2015Q1. It deploys both the Johansen cointegration approach and the autoregressive distributed lag (ARDL) cointegration approach to investigate for Australia whether money, real output, prices and the exchange rate (non‐stationary variables) maintain the long‐run price‐level relationship that the classical monetary theory suggests in the presence of such stationary variables as the domestic and foreign interest rates. As expected, the empirical findings for Australia are consistent with the classical long‐run price‐level relationship between money, real output, prices and the exchange rate. The error‐correction model of inflation confirms the presence of a cointegral relationship among these variables; it also provides strong evidence of a short‐run causal relationship between money supply growth and inflation. On the basis of a priori theoretical predictions and empirical findings, the paper draws the conclusion that the monetary aggregate and its growth rate matter insofar as inflation is concerned, irrespective of the strategy of monetary policy for price stability.     

Tobin's Q channel and monetary policy rules under incomplete exchange rate pass-through

This paper focuses on the role of the Tobin's Q channel in a two-country framework in which exporting firms set their prices on the basis of local currency pricing. Incomplete exchange rate pass-through significantly affects the Tobin's Q channel in each country compared with the case of complete exchange rate pass-through. We explore whether different specifications of monetary policy enhance social welfare. Regardless of the degree of home bias, a monetary policy rule that stabilizes domestic asset prices attains preferable outcomes to several alternative policy rules considered in our analysis. Notably, there are large gains from employing a domestic asset price rule when the home bias is large. A monetary policy rule that stabilizes the asset prices of both countries results in worse outcomes. Our simulation results suggest that stabilizing asset prices is important in an open economy with incomplete exchange rate pass-through.
