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.     

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.     

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。     

PRODUCTIVE GOVERNMENT EXPENDITURE IN MONETARY BUSINESS CYCLE MODELS

This paper assesses the transmission of fiscal policy shocks in a New Keynesian framework where government expenditures contribute to aggregate production. It is shown that even if the impact of government expenditures on production is small, this assumption helps to reconcile the models' predictions about fiscal policy effects with recent empirical evidence. In particular, it is shown that government expenditures can lead to a rise in private consumption, real wages, and employment if the government share is not too large and public finance does not solely rely on distortionary taxation. When government expenditures are partially financed by public debt, unit labor costs fall in response to a fiscal expansion, such that inflation tends to decline. Households are willing to raise consumption if monetary policy is active, i.e. ensures that the real interest rate rises with inflation. Otherwise, private consumption can also be crowded out, as in the conventional case where government expenditures are not productive.     

The macroeconomic effects of fiscal policy in Portugal: a Bayesian SVAR analysis

With a new quarterly dataset we estimate a Bayesian Structural Autoregression model and a Fully Simultaneous System approach to analyze the macroeconomic effects of fiscal policy. Results show that positive government spending shocks, in general, have a negative effect on real GDP; lead to “crowding-out” effects of private consumption and investment; have a persistent and positive effect on the price level and a mixed impact on the average financing cost of government debt. Explicitly considering the government debt dynamics in the model is also important. A VAR counter-factual exercise confirms that unexpected positive spending shocks create relevant “crowding-out” effects.     

Financial markets’ behavior around episodes of large changes in the fiscal stance

Using a panel of OECD countries from 1960 to 2002, this paper shows that interest rates, particularly those of long-term government bonds, decrease when countries’ fiscal position improves and increase around periods of budget deteriorations. Stock market prices surge around times of substantial fiscal tightening and plunge in periods of very loose fiscal policy. In addition, the paper shows that results depend on countries’ initial fiscal conditions and on the type of fiscal consolidations: Fiscal adjustments that occur in country-years with high levels of government deficit, that are implemented by cutting government spending, and that generate a permanent and substantial decrease in government debt are associated with larger reductions in interest rates and increases in stock market prices.     

Using time-varying transition probabilities in Markov switching processes to adjust US fiscal policy for asset prices

This paper tests for nonlinear effects of asset prices on the US fiscal policy. By modeling government spending and taxes as time-varying transition probability Markovian processes (TVPMS), we find that taxes significantly adjust in a nonlinear fashion to asset prices. In particular, taxes respond to housing and (to a smaller extent) to stock price changes during normal times. However, at periods characterized by high financial volatility, government taxation only counteracts stock market developments (and not the dynamics of the housing sector). As for government spending, it is neutral vis-a-vis the asset market cycles. We conclude that, correcting the fiscal balance and, notably, the revenue side for time-varying effects of asset prices provides a more accurate assessment of the fiscal stance and its sustainability.     

Variation in the fiscal multiplier with the method of financing: evidence across industrial countries

Government spending has often varied with the business cycle to stimulate the economy and to revive economic conditions. However, the state of public finances has often necessitated higher borrowing to finance widening fiscal deficits. Indeed, recent austerity packages around the globe have crystalized the importance of fiscal consolidation against the backdrop of rising public debt. To shed light on recent debates regarding fiscal multipliers, the article estimates variation in these multipliers with the method of financing, using annual data for a sample of industrial countries. There is a large variation in the effects of expansionary and contractinary government spending shocks on economic variables within and across countries. The significant effects of negative government spending shocks (fiscal contraction) appear more prevalent than those of expansionary shocks on real output growth, price inflation and nominal wage inflation. Consistent with theory’s predictions, the fiscal multiplier is more likely to be negative when government spending is financed by issuing debt and less likely in the case of monetization. The evidence confirms concerns about the negative effect of higher debt and more expensive financing on private activity, countering the effectiveness of fiscal policy.     

Optimal fiscal and monetary policies in the face of rare disasters

This paper studies optimal fiscal and monetary policies in an economy exposed to large adverse shocks (rare disasters). We contrast optimal policies under commitment and discretion and identify several striking differences between these institutional environments. A government that can commit to its policy plans relies heavily on debt to smooth the adverse effects of large shocks over time. Lack of commitment seriously limits the government's ability to use debt as a shock absorber. Under discretion, an increase in debt leads to an increase in inflation expectations and therefore higher nominal interest rate distortions. Hence, the discretionary government keeps debt in close vicinity of its steady-state level, and the response of taxes, inflation, and interest rates to shocks is much more pronounced under discretion than under commitment. This is particularly relevant for large shocks and when the initial stock of government debt is already high at the time the shock occurs. We also argue that the adverse welfare effects of disasters are larger under discretion than under commitment, but these welfare differentials can be significantly reduced by making the discretionary government inflation averse.     

政府债务会影响财政支出的乘数效应吗?—来自跨国面板数据的经验证据

文章在构建一个局部均衡模型的基础上,采用150个国家(地区)2000?2014年的面板数据,实证考察了政府债务对财政支出乘数效应的影响,得到了与理论预期一致的经验证据.结果表明:(1)政府债务会显著影响财政支出的乘数效应.随着政府债务水平的提高,财政支出的乘数效应趋于减弱.尤其是在克服内生性问题之后,这一结论仍然成立;(2)政府债务作用存在显著的非线性特征.当政府债务占GDP的比重突破88%的阈值后,财政支出的乘数效应会在低债务国家和高债务国家之间发生非常迅速的逆向转换;(3)对中国这样的低债务国家,顺周期的财政政策运用是非常有效的.而对美国、希腊等已经处于高债务水平的国家,采取逆周期的财政政策才能避免潜在的经济波动风险.     

Fiscal policy and national saving

This paper uses structural vector autoregressions along with structural measures of fiscal policy to measure the dynamic impact of fiscal policy shocks on the output gap and national saving. Positive shocks to government purchases and negative shocks to real net taxes are found to increase the output gap. Positive shocks to the government's structural surplus increases national saving although the effects are small. Positive shocks to government purchases are found to substantially reduce national saving. Negative shocks to real net tax revenues as a share of potential GDP have a small negative impact on national saving.     

Inflation and the Impact of Budgets

This article focuses on the adjustment of budget figures for the effect of inflation on the value of government debt. It asks whether such adjustment improves their performance as a measure of 'fiscal impact'. If inflation significantly influences the impact of budgets on the real economy, policy-makers may make inappropriate fiscal policy decisions if they are guided by unadjusted budget figures. The article argues that if agents perceive holdings of government debt as part of their wealth, changes in the real value of debt will have an effect on consumption behaviour. Therefore to assess the impact of fiscal policy on consumption it may be necessary to adjust budget figures so that they accurately indicate changes in the real value of debt held by the private sector. This article adjusts a series of structural public sector borrowing requirements (PSBR) for the effect of inflation on the real value of government debt held by the private sector. An empirical analysis concludes that the inflation-adjusted budget series provides a superior measure of fiscal impact on consumption, and hence the real economy.     

Compatibility between monetary and fiscal policy under EMU

The debate over the Stability and Growth Pact (SGP) as a part of European Monetary Union, has highlighted the need to assess the extent to which fiscal policies of union members should be constrained as a pre-requisite for price stability within the union. In this paper, we develop a two country open economy model, where each country has overlapping generations of finitely lived consumers who supply labour to imperfectly competitive firms which can only change their prices infrequently. We examine the case where the two countries have formed a monetary union, but where the fiscal authorities remain independent. We show that the fiscal response required to ensure stability of the real debt stock is greater when consumers are not infinitely lived. In principle, this allows for some compensating behaviour between governments, but we show that the scope for compensation is limited. The monetary authority can abandon its active targeting of inflation to stabilise the debt of at most one fiscal authority, and any other combination of policies will either result in price level indeterminacy and/or indefinite transfers of wealth between the two economies. Finally, in a series of simulations we show that fiscal shocks have limited impact on output and inflation provided the fiscal authorities meet the (weak) requirements of fiscal solvency. However, when monetary policy is forced to abandon its active targeting of inflation, then fiscal shocks have a much greater impact on both output and inflation.     

Global capital markets,housing prices,and partisan fiscal policies

In recent years, global imbalances have channeled the excess savings of surplus countries toward the real estate markets of deficit countries. By consequence, the deficit countries that attracted lots of foreign capital experienced large run‐ups in house prices, whereas most surplus countries that exported capital exhibited flat or slow house price growth. We first use new house price data and a novel instrumental variable design to show the causal relationship between housing prices and capital inflows, particularly through debt bonanzas. We then argue that international capital flows affect the fiscal policy preferences of both voters and political parties by way of their impact on housing prices. Where capital inflows are large and housing prices are rising, we expect voters to respond by demanding both lower taxes and less publicly‐provided social insurance because rising house prices allow homeowners to self‐insure against income loss. In contrast, declining house prices produce greater demands for social insurance, particularly among those most exposed to housing market risk. We present evidence from two cross‐national surveys that supports these claims, as well as a “before and after” analysis of the housing crash in Eastern Europe. We also show that the connection between house prices and social policy also manifests itself in government spending outcomes, mediated by partisan control.     

The asymmetric effects of investor sentiment and monetary policy on stock prices

We examine the impact of investor sentiment and monetary policy on the stock prices under different market states based on the Markov-switching vector autoregression (MS-VAR) model. The results show that the sentiment shocks, more than monetary policy shocks, lead to not only much larger fluctuations of stock prices but also much longer duration in the stock market downturn than in the stock market expansion, which shows obvious asymmetric effect. Moreover, the responses of stock prices to the sentiment shocks present an immediate effect, while the responses of stock prices to the monetary policy shocks show one-period lag effect.     

Foreign Debt,Foreign Direct Investment and Volatility

We investigate how foreign debt and foreign direct investment (FDI) affect the growth and welfare of a stochastically growing small open economy. First, we find that foreign debt influences the growth of domestic wealth by lowering the cost of capital, while FDI affects the country's welfare by providing an additional source of permanent income. Second, a decline in domestic investment may improve domestic welfare as FDI replaces the gap. Even when the welfare deteriorates, its magnitude is mitigated, leaving more room for discretionary fiscal policy. Third, a fiscal policy aimed to stabilize domestic output fluctuations needs to be conducted not to crowd out the welfare benefit of FDI too much. Fourth, an economy with both types of foreign capital experiences wider welfare swings by external volatility shocks than the one with foreign debt alone, while the welfare effects from domestic volatility shocks are mitigated. The welfare effects of fiscal shocks are much smaller with both types of foreign capital. Lastly, the first-best labor income tax covers the government absorption by the labor's share of total output, and the capital income tax covers the rest. Investment is penalized or subsidized depending on the social marginal cost-gain differential.     

Housing prices and population dynamics in urban China

In this study, a dynamic stochastic general equilibrium (DSGE) model is used to investigate the influence of population on housing price dynamics in urban China. The contribution of population growth to the housing price trend and the contribution of population shocks to housing price fluctuations are quantitatively measured. The empirical results indicate that the ongoing policy to control the population size in large cities in China can decrease the growth rate of housing prices by 0.49% every year, which accounts for 1/10 of the total housing price trend. Furthermore, this policy cannot stabilize housing prices because population shocks have negligible effects on the housing price cycle. Housing technology shocks and housing preference shocks are responsible for most of the housing price fluctuations.     

The transmission of financial shocks in an estimated DSGE model with housing and banking

We develop a dynamic stochastic general equilibrium (DSGE) model with housing and banking to study the transmission of financial shocks between the financial and real sectors. A deterioration in the bank's balance sheet induced by financial shocks could have amplified and persistent impacts on real activities. The amplification of the shocks are originated from financial frictions tied to households and banks. We find that a disruption in bank net worth initiated by capital quality shocks generates a decline in household loans, house prices and output. Bank liquidity shocks also have negative effects on these variables. Housing preference shocks could generate a positive comovement between house prices and output. All these findings are qualitatively consistent with empirical evidence, suggesting that these financial shocks are critical to the dynamics of house prices and other macroeconomic variables.     

Government debt,inflation dynamics and the transmission of fiscal policy shocks

We analyze the influence of the fiscal position on the transmission of government spending shocks in a New Keynesian model. We find that once we allow for positive levels of government debt in the steady state, the size of the fiscal multiplier depends strongly on the horizon at which the multiplier is evaluated. While the long-run effect of a fiscal policy innovation is typically of a similar order of magnitude as in Galí et al. (2007), short-run multipliers differ substantially. The reason for this non-monotonic behavior is the interaction between the dynamics of the inflation rate and the debt level in real terms for sufficiently high levels of government debt in the steady state.     

Housing,consumption and monetary policy: how different are the first-, second- and third-tier cities in China?

This article presents an empirical analysis of the relationship between house prices and the real economy in China’s first-, second- and third-tier cities. A Structural Vector Autoregression model is applied to study the impacts of monetary policy shocks and housing demand shocks on various housing markets across China. We also investigate the role of house prices in the transmission mechanism of monetary policy. The results reveal that in first-tier cities, raising interest rates has a stronger negative effect on house prices. Also, as house prices decrease in first-tier cities, private consumption declines sharply. There is a stronger role of housing markets in the transmission of monetary policy shocks in these cities. Our findings indicate that interest rate adjustment could effectively curb spikes in housing prices in the first-tier cities, but the impact of such adjustments on household consumption must also be considered.
