Cooperative fiscal policy at the zero lower bound

This paper investigates the use of fiscal policy in response to a large negative aggregate demand shock which may push the global economy into a liquidity trap. Fiscal policy may be an effective tool to respond to a liquidity trap, but its international spillover effects may operate quite differently from its domestic effects. We derive the optimal cooperative fiscal response to a global liquidity trap in a two country world economy. Surprisingly, we find that the optimal fiscal spending response for a partner country to a negative aggregate demand shock in a source country may be negative. If fiscal policy can be chosen under policy commitment, the optimal response involves current fiscal expansion combined with future fiscal contraction, after the liquidity trap has ended.     

Fiscal sustainability in Japan

This paper investigates fiscal sustainability of Japan by providing a dynamic stochastic general equilibrium (DSGE) model that features the low interest rate of the government bond relative to the economic growth rate to mimic the actual data. We evaluate fiscal sustainability by investigating whether the expected path of the debt-to-GDP ratio stabilizes or increases without bound. The debt-to-GDP ratio depends crucially on the projected growth rate and the fiscal policy rule. If the government does not react to the current fiscal crisis, the debt-to-GDP ratio will increase without bound, and then the fiscal policy is not sustainable. If the fiscal rule uses Bohn’s (1998) idea that involves the response of the primary surplus to the debt, sustainability improves. This rule provides a useful and realistic reform plan in the short and long runs.     

Monetary vs. fiscal policy: Some evidence from vector autoregression for India

This paper investigates the relative importance of monetary and fiscal policy for India. Unlike previous studies, a more general approach of multivariate vector autoregression has been employed. Analysis of the causality results based on the joint F-tests and the dynamic multipliers based on the variance decompositions and the impulse response functions unambiguously support the Keynesian stance on the importance of fiscal policy. There is very little evidence of exogeneity of money supply, undermining the validity of the monetarist proposition. On the contrary, Indian monetary policy appears to have accommodated changes in government expenditure, prices and output, lending support to the structuralist-Mundellian views.     

Fiscal policy switching in Japan, the US, and the UK

This paper estimates fiscal policy feedback rules in Japan, the United States, and the United Kingdom for more than a century, allowing for stochastic regime changes. Estimating a Markov-switching model by the Bayesian method, we find the following: First, the Japanese data clearly reject the view that the fiscal policy regime is fixed, i.e., that the Japanese government adopted a Ricardian or a non-Ricardian regime throughout the entire period. Instead, our results indicate a stochastic switch of the debt-GDP ratio between stationary and nonstationary processes, and thus a stochastic switch between Ricardian and non-Ricardian regimes. Second, our simulation exercises using the estimated parameters and transition probabilities do not necessarily reject the possibility that the debt-GDP ratio may be nonstationary even in the long run (i.e., globally nonstationary). Third, the Japanese result is in sharp contrast with the results for the US and the UK which indicate that in these countries the government’s fiscal behavior is consistently characterized by Ricardian policy.     

Bayesian analysis of time-varying parameter vector autoregressive model for the Japanese economy and monetary policy

This paper analyzes the time-varying parameter vector autoregressive (TVP–VAR) model for the Japanese economy and monetary policy. The parameters are allowed to follow a random walk process and estimated using the Markov chain Monte Carlo method. The empirical result reveals the time-varying structure of the Japanese economy and monetary policy during the period from 1981 to 2008. The marginal likelihoods of the TVP–VAR model and other fixed parameter VAR models are estimated for model comparison. The estimated marginal likelihoods indicate that the TVP–VAR model best fits the Japanese economic data.     

Learning the fiscal theory of the price level: Some consequences of debt-management policy

This paper examines the consequences of the scale and composition of the public debt in policy regimes in which monetary policy is ‘passive’ and fiscal policy ‘active’. This configuration of policy is argued to be of both historical and contemporary interest, in economies such as the US and Japan. It is shown that higher average levels and moderate average maturities of debt can induce macroeconomic instability for a range of policies specified as simple rules. However, interest-rate pegs combined with active fiscal policies almost always ensure macroeconomic stability. This suggests that in periods where the zero lower bound on nominal interest rates is a relevant constraint on policy design, a switch in fiscal regime is desirable.     

Cost heterogeneity and the destination of Japanese foreign direct investment: A theoretical and empirical analysis

This paper first of all develops a Cournot oligopolistic model with heterogeneous firms to examine each firm's choice between export-oriented foreign direct investments (FDI) and FDI to serve the host-country market. It is shown that there exist a critical level of efficiency such that all firms below that level choose the former and those above it the latter. The hypothesis is tested using firm-level data on 118,300 Japanese firms covering the entire manufacturing sector. Multinomial logit estimates strongly support our theoretical findings.     

Monetary policy rules for a developing country: Evidence from Pakistan

This paper estimates forward-looking monetary policy rules to examine the interest rate setting behavior of the State Bank of Pakistan. Considering the external constraints on monetary policy, core inflation and a country-specific measure of the output gap, we demonstrate that the State Bank of Pakistan reacts to changes in inflation, the output gap and the federal funds rate.     

Is there any gain from social security privatization?

Increasing calls for a social security reform of switching from the pay-as-you-go (PAYG) system to a funded system has been seen in recent decades. This paper examines the effect of this reform on capital accumulation and the welfare of each generation. Three methods are used to finance the pension debt, government debt financing, tax financing, and government asset financing. With government debt or tax financing, the market equilibrium remains unchanged and all generations are as well off in the new system as in the PAYG system. Thus, switching from the PAYG system to a funded system is neutral. With government asset financing, the interest rate will decrease, private capital will increase, but the total output may either increase or decrease. The welfare effect is also ambiguous in general, depending on the rate of return of government assets. With plausible parameters, our simulation shows that the reform will lower the interest rate, increase private capital, and lower government capital in the short run, but raise government capital and increase output in the long run.     

Korea's liberalization policy directives and Korea's weakening competitiveness

Recently, Korea's export growth rate is decreasing and its trade level staggering. Since Korea has few natural resources and is highly dependent on trade, this recent trend signals a serious problem lying ahead. In this paper, we look at internal and external factors weakening Korea's competitiveness in the world market and suggest liberalization policy guidelines to improve its competitiveness.     

Can inflation targeting regimes be effective in developing countries? The Turkish experience

This paper examines the performance of Turkey's inflation targeting (IT) experience. We find the IT regime to be an effective framework. Our judgment is based on three broad conclusions supported by empirical analyses. First, fiscal stability is an effective tool for a successful monetary policy. Second, the overnight policy of the Central Bank of Turkey rate is a significant determinant of the changes in market lending rates, which is the preliminary step in the monetary transmission mechanism. Third, recent developments on the broader issue of the effectiveness of interest rate policy in controlling inflation through aggregate demand management and through other channels are encouraging. Based on our findings, we argue that the impact of policy rate changes on economic activity and inflation have become more predictable and changed in the direction in line with theory, improving the transmission capacity of monetary policy.     

Japanese foreign direct investment and regional trade

We examine the relationship between Japanese FDI outflows, domestic and foreign fixed investment, and the exchange rate. The results indicate that aggregate FDI outflows have been driven by investment in Japan and the exchange rate, while the geographic distribution of such investment has been influenced by foreign economic conditions. We also find that FDI outflows have a temporary impact on exports but a permanent effect on imports. We find no evidence that behavior with respect to East Asia differs from that with respect to North America or Europe.     

Does fiscal policy influence monetary policy? The case of Spain, 1874-1935

The Spanish peseta never formally belonged to the gold club, neither the classical nor the exchange-rate gold standards. It has been traditionally argued that the reason was the predominance of deficits in the Spanish budget from 1874 to 1935. The financing needs of the Treasury led to money creation and, consequently, to sacrificing the gold commitment and a fixed exchange rate. Applying a stationary VAR (Vector AutoRegressive) model, this paper estimates the dynamic link between budget and money and tests whether Spanish fiscal policy actually influenced monetary policy. The results confirm the dominance of fiscal policy for the period and, therefore, provide empirical support to the idea that the problems of the Treasury were behind Spain’s renouncement of gold.     

Responding to the global financial crisis: Vietnamese exchange rate policy, 2008–2009

The paper presents an analysis of exchange rate policy in Vietnam during 2008–2009. In early 2008, the country faced a sudden reversal of capital flows as signs of developing domestic vulnerabilities became evident. The downward pressure on the dong then intensified with the onset of the global financial crisis in the fall. In these environments, the Vietnamese authorities responded with various exchange rate policy measures. The paper documents a shift in Vietnam's de facto exchange rate regime, from a basket peg to a simple US dollar peg, when the domestic vulnerabilities became compounded by the evolving global crisis. The authorities utilized additional measures to relieve pressure on the parallel exchange rate. An event study methodology finds little evidence of systematic effectiveness for these policy actions; any effectiveness was short-lived. A close examination of individual actions suggests that the impact of foreign exchange market intervention appeared more consistent than any other type of measure and most effective when combined with other measures.     

Political instability and inflation in Pakistan

This study investigates the effects of political instability on inflation in Pakistan. Applying the Generalized Method of Moments technique and using data from 1951 to 2007, we examine this link through two different models. The results of the ‘monetary’ model suggest that the effects of monetary determinants are rather marginal and that they depend upon the political environment of Pakistan. The ‘nonmonetary’ model's findings explicitly establish a positive association between political instability and inflation. This is further confirmed through analysis based on interactive dummies that reveal political instability significantly leading to high (above average) inflation.     

A politically feasible social security reform with a two-tier structure

This paper investigates the welfare implications and political feasibility of social security reforms with a two-tier structure in Japan. We evaluate social security reforms from two points of view: (i) the ex-ante expected value of future generations, and (ii) whether current generations prefer reform to the status-quo system, which we call political feasibility. To evaluate the reforms, we use a large-scale overlapping generations model with idiosyncratic income risk and a two-tier structure. The first tier guarantees a basic pension and the second tier consists of the earnings-related part. Calibrating the parameters of the model to the Japanese economy, we compute the transition path and the two welfare criteria. We find that, given the two-tier structure in Japan, an increase in the basic pension and the abolition of the earnings-related part of the social security system improve the welfare of future generations, and ensures political feasibility when a consumption tax is the source of revenue.     

What causes business cycles? Analysis of the Japanese industrial production data

We explore what causes business cycles by analyzing the Japanese industrial production data. The methods used are spectral analysis and factor analysis. Using the random matrix theory, we show that two largest eigenvalues are significant. Taking advantage of the information revealed by disaggregated data, we identify the first dominant factor as the aggregate demand, and the second factor as inventory adjustment. They cannot be reasonably interpreted as technological shocks. We also demonstrate that in terms of two dominant factors, shipments lead production by four months. Furthermore, out-of-sample test demonstrates that the model holds up even under the 2008–2009 recession. Because a fall of output during 2008–2009 was caused by an exogenous drop in exports, it provides another justification for identifying the first dominant factor as the aggregate demand. All the findings suggest that the major cause of business cycles is real demand shocks.     

Money demand in China and time-varying cointegration

Many studies analyze the money demand using a (fixed coefficient) cointegrating regression model, which may not be appropriate to deal with the money demand of a transition economy like China. This paper investigates this issue using a time-varying cointegration approach based on the quarterly data from 1996 to 2009. We find some interesting results: (i) the estimates of the income elasticities are between 0.60 and 0.75, which are comparable with the previous studies; (ii) the estimated interest rate elasticity supports the argument that the overall effect of the interest rate on the money holding is weak although there are some mild evidences that it has been strengthened in recent years; (iii) the substitution effect of equity asset dominates the wealth effect, especially, during the bullish market period. Our result is robust to the alternative choices of the scale or opportunity cost variables and shows that omission of the stock prices in the money demand function would possibly yield a misspecification problem.
