The Composition of Government Spending and the Real Exchange Rate

We show that the composition of government spending influences the long-run behavior of the real exchange rate. We develop a two-sector small open-economy model in which an increase in government consumption is associated with real appreciation, while an increase in government investment may generate real depreciation. Our empirical work confirms that government consumption and government investment have differential effects on the real exchange rate and the relative price of nontradables.     

收入不平等、政府支出与实际汇率——基于跨国面板数据的研究

已有较多研究讨论了实际汇率的决定因素,而从收入不平等角度出发的研究并不多。本文搜集和整理了172个国家和地区1970年到2016年的跨国面板数据,分析了收入不平等对一国实际汇率的影响,并引入政府支出探究了收入分配对非贸易品部门和实际汇率的影响机制。实证检验结果表明,对于非OECD国家,收入不平等和实际汇率显著负相关,即收入越不平等,实际汇率高估越严重,而在OECD国家中这一现象并不存在。进一步的影响机制分析发现,对于非OECD国家,一国收入不平等加剧会导致该国政府支出增多,从而扩大了非贸易品部门规模,导致非贸易品的相对价格上升,使得实际汇率高估。     

The macroeconomic effects of monetary and fiscal policy in a small open economy: Does the exchange rate regime matter?

This paper develops a small open economy model in the spirit of Obstfeld and Rogoff (1995). The introduction of endogenous traded sector output unlocks current account and real exchange rate effects. Within this framework where specific consideration is given to the case with fixed but adjustable parities, exchange rate devaluation generates similar qualitative effects as a money supply expansion under floating rates. Output and external effects of government spending shocks are broadly consistent with the adjusted basic non-micro founded Mundell and Fleming (MF) framework, but differ in significant ways from the baseline MF model. Contrary to the textbook MF model a government expenditure shock depreciates the nominal exchange rate and generates real effects under the fixed rate system.     

Consumption,government spending,and the real exchange rate

Using panel structural VAR analysis and quarterly data from four industrialized countries, we document that an increase in government purchases raises output and private consumption, deteriorates the trade balance, and depreciates the real exchange rate. This pattern of comovement poses a puzzle for both neoclassical and Keynesian models. An explanation based on the deep-habit mechanism is proposed. An estimated two-country model with deep-habits is shown to replicate well the observed responses of output, consumption, and the trade balance, and the initial response of the real exchange rate to an estimated government spending shock.     

Dynamic effects of government policies in an open economy

The effects of three government policies, an increase in the provision of government services, an open market operation, and an increase in the rate of growth of government liabilities, are studied in a long-run model of a small open economy with flexible exchange rates. The government budget constraint, the degree to which government bonds are net wealth to the public, and the degree of substitutability of government services for private market purchases are all considered. The determination of the exchange rate and the adjustment of the accounts of the balance of payments to changes in government policy are explored.     

Does Consumption Respond More to Housing Wealth Than to Financial Market Wealth? If So,Why?

This paper uses long-run equilibrium relationship between consumption and different components of wealth to estimate the effect of changes in housing wealth and financial wealth on consumption. By exploiting this long-run property, it has been shown that a dollar increase in housing wealth increases consumption by seven cents, whereas, a corresponding dollar increase in financial wealth increases consumption by only three cents. This difference in the wealth effect arises because transitory shocks dominate variation in financial wealth, whereas permanent shocks account for most of the variation in housing wealth. This paper also shows that the relative importance of permanent component for housing wealth has witnessed an increase over the last thirty years. Therefore, housing wealth effect has also increased over time.     

Estimating exchange rate responsiveness to shocks

The goal of this paper is to examine the importance of permanent and transitory shocks using a more efficient trend-cycle decomposition of the real exchange rate series. Our main contribution is that in measuring the impact of shocks, we not only impose common trend restrictions but also common cycle restrictions. We later confirm, through a post sample forecasting exercise, the efficiency gains from imposing common cycle restrictions. Our results indicate that permanent shocks are responsible for the bulk of the real exchange rate variations for Japan, Italy, Germany, France, and the UK vis-à-vis the US dollar over short horizons. For Canada, however, transitory shocks are dominant over the short horizon. In sum, while for Japan, France, and Italy, around 15% of the variation in real exchange rate is due to transitory shocks, for Canada, Germany and the UK, over 25% of the variations over the short horizon are due to transitory shocks. Thus, we claim that the role of transitory shocks should not be ignored.     

Real asset returns,inflation and activity in a small,open, Cash-in-Advance economy

The effects of inflation are worked out for a small open economy with Cash-in-Advance (CIA) constraints on bond purchases. If all transactions are subject to CIA constraints, an increase in the inflation rate will reduce savings, bringing about a current account deficit, while the capital stock will be unaffected. If investment is not subject to CIA constraints, an increase in the inflation rate will encourage investment and reduce savings, bringing about a current account deficit. Numerical evaluation of the model gives rise to falls in real interest rates that are in line with recent empirical findings.     

The current account and the optimal government debt

In this paper we analyze the optimal response of the current account and the government debt to real disturbances, permanent and temporary. Lumpsum taxes are not feasible and the government income is raised according to the Ramsey rule for optimum taxation. We show that permanent disturbances have no effects on either the private or the government current account if initially there are no deficits. Starting off from the same initial situation both the private sector and the government develop a deficit on current account in response to a temporary disturbance.     

Fiscal Policy and the Terms of Trade in an Analytical Two-Country Dynamic Model

This paper presents a two-country dynamic perfect foresight Ricardian model with wealth effects to study the relationship between government spending financed by alternative taxation, the terms of trade and welfare. An increase in domestic government spending financed by a distortionary capital income tax leads the real exchange rate initially to appreciate (a pure demand effect). But along the transitional path an intertemporal terms of trade effect (a supply side effect) operates and the real exchange rate depreciates to a steady state value ultimately higher relative to the initial equilibrium. The welfare of the domestic resident increases due to a reversed immiserizing growth effect.     

Effects of budgetary policies in open economies: The role of intertemporal consumption substitution

An economy's optimal response to temporary and anticipated future changes in government spending is examined in the context of a two-country model which highlights the role of intertemporal consumption substitution (ICS). Special attention is devoted to the case in which the two countries coordinate their fiscal measures. The qualitative effects of such measures on an economy's current account, terms of trade (in a two-commodity world), and real exchange and interest rates (in a world with non-traded goods) are shown to depend on the relationship between the domestic and the foreign elasticities of ICS.     

Revisiting the supply side effects of government spending

We revisit the macroeconomic effects of government consumption in the neoclassical growth model when agents face uninsured idiosyncratic investment risk. Under complete markets, a permanent increase in government consumption has no long-run effect on interest rates and capital intensity, while it increases work hours due to the negative wealth effect. These results are upset once we allow for incomplete markets. The same negative wealth effect now causes a reduction in risk taking and the demand for investment. This leads to a lower risk-free rate and, under certain conditions, also to a lower capital-labor ratio and lower productivity.     

Real exchange rates under alternative nominal exchange-rate systems

The paper develops an equilibrium model of the determination of exchange rates, the relative price of nontraded goods, and the current account. The focus is on the effects of various real and nominal disturbances and the conditions under which the nominal exchange-rate system is neutral with respect to real variables in the economy. The model demonstrates an assymetry in the roles of trade and nontraded goods in affecting exchange rates. An econometric investigation of the raltion between the exchange-rate system and the variability of real exchange rates provides some evidence against the neutrality hypothesis.     

Taylor rules and the Canadian–US equilibrium exchange rate

This paper identifies the Canadian–US equilibrium exchange rate based on a simple structural model of the real exchange rate, in which monetary policy follows a Taylor-rule interest rate reaction function. The exchange rate is explained by relative output and inflation as observable variables, and by unobserved equilibrium rates as well as unobserved transitory components in output and the exchange rate. Using Canadian data over 1974–2009 we jointly estimate the unobserved components and the structural parameters using the Kalman filter and Bayesian technique. We find that Canada's equilibrium exchange rate evolves smoothly and follows a trend depreciation. The transitory component is found to be very persistent but much more volatile than the equilibrium rate, resulting in few but prolonged periods of currency misalignments.     

Exchange rate mean reversion from real shocks within an intertemporal equilibrium model

The post Bretton Woods era has been characterized by real exchange rates that exhibit mean reversion, with mixed evidence as to whether this reversion is partial (PPP never holds) or essentially complete. This paper generates these stylized facts theoretically by synthesizing a simple intertemporal open economy model with the elasticities approach to the current account. A central feature of the model is the existence of non-traded goods. The model can generate partial or approximately complete mean reversion for the real exchange rate (depending on parameter values) if innovations in output are made up of permanent and temporary components. In addition, temporary output shocks generate a type of hysteresis wherein the short-run path for the exchange rate permanently alters its long-run equilibrium value.     

Expectations,the exchange rate,and the current account

A critical examination is undertaken of the relationship between the exchange rate and the current account in a small open economy. Theoretically, the correlation between the exchange rate and the current account seems to be ambiguous. In particular, the association between movements in the exchange rate and the current account is likely to depend in an essential manner on the nature of exogenous disturbances affecting the two variables simultaneously. Lastly, the question of the role of an optimal monetary policy and the choice of an exchange rate regime in an uncertain environment is raised.     

The U.S. evidence on optimal taxation over time

This paper considers a tax rule in which a uniform tax rate over time becomes optimal. Its implications are that (1) changes in the tax rate should arise only when there are changes in permanent government expenditures, and (2) no variable other than permanent government expenditures should be of any value in predicting the tax rate. These implications are tested, using U.S. data for 1937-82. Empirical results of the tests reveal that, in addition to responding to permanent government expenditures, the tax rate also responds to temporary defense purchases, the general price level, and a time trend.     

On the effectiveness of exchange rate interventions in emerging markets

We analyze the effectiveness of exchange rate interventions for a panel of 18 emerging market economies during the period 2003–2011. Using an error-correction model approach, we find that on average, intervention is effective in moving the real exchange rate in the desired direction, controlling for deviations from the equilibrium and short-term changes in fundamentals and global financial variables. Our results are robust to different samples and estimation methods. We find little evidence of asymmetries in the effect of sales and purchases, but some evidence of more effective interventions for large deviations from the equilibrium. We also explore differences across countries according to the possible transmission channels and nature of some global shocks.     

Output and employment in a macro model with discrete transaction costs

The paper develops a macro model for determining output and employment when discrete transaction costs exist for paying wages and for purchasing commodities. Household labor supply is a function of an effective real wage, which modifies the apparent real wage to take account of the length of the payment period and the costs associated with buying and holding commodities. Firm labor demand is derived in a model where there are lumpy payroll costs associated with making wage payments. The behavior of households and firms is brought together in a market-clearing framework to determine the values of the real wage, employment and output, as well as the time intervals between wage payments and purchases of commodities. The effects of changes in the transaction and holding cost parameters are then examined by comparative-static techniques. An increase in any of these cost parameters turns out to reduce output and the amount of labor employed in production, but also tends to raise the amount of labor absorbed by the process of transacting. The tendency of transaction labor to move in the opposite direction from production labor implies that the net effects on total work are ambiguous.     

Productivity shocks and real exchange rates

Previous studies have concluded that productivity shocks have negligible effects on real exchange rate fluctuations. This paper shows that when long-run equilibrium relationships between real exchange rate levels and fundamental variables are taken into account, relative productivity shocks account for most of the long-run movements in the real exchange rates. This can be interpreted as empirical support for the Balassa (1964. Journal of Political Economy 72, 584-596) and Samuelson (1964. Review of Economics and Statistics 46, 145-154) model where differences in relative productivity is the main source of long-run deviations for purchasing power parity.
