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.     

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.     

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.     

Chinese exchange rate and price effects on G3 import prices

This paper explores the degree of price and exchange rate interdependence between China and the G3 (US, Japan and the Euro-zone) by undertaking a VAR based shock analysis. A GARCH framework is also employed to derive the conditional variances to uncover the extent of volatility transmission. We address two key issues. First as there have been concerns about low value-added cheap Chinese goods flooding G3 markets, we attempt to measure the impact of Chinese prices on G3 import prices. Second, we focus on the transmission of exchange rate shocks – a subject which we approach by examining shocks in China's bilateral exchange rate with each of these major trading partners (the US, Japan and the Euro Area). Our results indicate that reduced import prices from China are the channel through which aggregate domestic prices in the G3 remain depressed, while the impact of the RMB exchange rate with G3 currencies appears less powerful. This finding implies that the Chinese authorities’ RMB exchange rate policy is relatively unimportant and, in particular, that a revaluation of the RMB would not do much to reduce the US trade deficit. In terms of volatility spillover, the relatively flexible RMB exchange rate against the Euro results in RMB-EUR volatility having a stronger influence than the more tightly controlled RMB-USD rate on the volatility of Chinese export prices.     

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.     

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.     

Exchange rate movements and foreign direct investment (FDI): Japanese investment in Asia, 1987–2008

The paper estimates the impact of exchange rate movements on foreign direct investment (FDI). By using the panel data of Japanese FDI flows to nine dynamic Asian economies during 1987–2008, the paper finds that (i) FDI declined with a depreciation of the yen against host country currencies; (ii) it increased with exchange rate volatility; and (iii) it was little affected by the Asian financial crisis, especially when disguised financial flows were removed from the data. A novel result concerns the negative response of FDI to the third moment of monthly exchange rate changes: the volume of FDI was smaller when the distribution was positively skewed (i.e., when the yen was biased towards relatively large depreciation shocks). If skewness proxies for expected mean-reverting changes, this supports the idea that source country investors care about the future stream of revenues and returns denominated in their own currency. These results are robust, with other standard control variables having statistically significant coefficients with expected signs.     

The Japanese trade balance: Recent history and future prospects

The rise in the yen in the early 1990s was held out as a `solution' to the persistent Japanese trade surplus. I argued, instead, that the sharp rise in the yen through mid-1993 would lead at most to a modest decline in net exports. This forecast, made in late 1993, was remarkably accurate, despite a subsequent fall in the dollar to 80 yen. It reflects a resilient feature of trade data known to most empirical researchers: that relative price movements account for only a fraction of observed movements in the balance of trade or current account.     

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.     

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.     

Revisiting long-run purchasing power parity with asymmetric adjustment for G-7 countries

In this study, we applied a threshold cointegration test advanced by Enders and Siklos (2001) to investigate the properties of asymmetric adjustment on long-run purchasing power parity (PPP) in G-7 countries between January 1994 and April 2010. Although there was strong evidence of long-run PPP for these G-7 countries, with the exception of Canada, the adjustment mechanism was asymmetric. These results have important policy implications for G-7 countries.     

A decomposition analysis of income inequality of Chinese rural households

This paper reports an application of household survey data collected from grain producing areas in five provinces of China to issues of the determinants of rural inequality. Previous studies suggest that non-agricultural activities have been the major cause of rural income inequality, which has important implications for policy formulation. However, our results show that inequality within the grain producing areas was also very high, with differences in crop income as the major source of inequality. The policy implications are also different from those of previous studies. While some suggest that an increase in agricultural income can reduce inequality, our results indicate that this is not universally true. In some cases, whether the increase in crop income has come from state procurement also matters. These results call for a more cautious and area-specific approach to policy formulation as far as inequality is concerned.     

The role of production fragmentation in international business cycle synchronization in East Asia

This paper analyzes factors contributing to the observed increase in international business cycle synchronization between eight East Asian developing countries and the major developed economies of Japan and the United States. To this end, a two-country dynamic general equilibrium (DGE) model is proposed which focuses on the role of production fragmentation among these countries. A key feature of the model is that it includes the trade in differentiated capital goods, which are added to the capital stock for production, and the technology embodied in these capital goods. The parameters of the model are calibrated using actual data of the countries included. Model simulations are conducted for two periods (1993–1997 and 1999–2005), before and after the Asian financial crisis, showing that the increase in business cycle synchronization can be attributed mainly to the growing fragmentation of production activities.     

Asian holding of US Treasury securities: Trade integration as a threshold

This paper empirically investigates if there have been any shifts in regimes with Asian holding of US long-term Treasury securities with particular attention paid to the role of growing regional integration in trade. A panel regression estimation of eight Asian countries for 1998–2004 confirms the striking persistency of the portfolio weight of US Treasury securities. It also reveals, without a surprise, that the traditionally strong trade link with US as well as exchange rate regime and volatility of local currency bond index explain observed overinvestment in US Treasury securities deviating from what can be warranted by the market share of the US Treasury securities. What is interesting, however, is the estimated regime switches as found when examined with a threshold estimation (Hansen, 1999). We find three thresholds which divide the sample into four regimes—a decreasing persistency as intraregional trade link becomes tighter.     

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.     

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.     

Restructuring of financial institutions and the corporate sector in Korea

This paper explores causes of the Korean currency crisis which started in November 1997. This paper also presents restructuring proposals and introduces the progress made so far. The urgency for quick restructuring and the necessity of the injection of money from both the government and foreign investors are emphasized. Restructuring of financial and corporate sectors should be pursued simultaneously. In the financial sector, the restructuring of banks should take precedence over other financial institutions. The key task in terms of bank restructuring involves the resolution of bad loans, recapitalization and the expedited reorganization of nonviable banks. Corporate reform is also important. Banks should play a central role in corporate workouts, especially in lowering excessive corporate debt and triggering corporate restructuring based on core competence. Transparency of corporate management, internationally accepted accounting practices, fuller disclosure requirements and stronger monitoring by minority shareholders are prerequisites for effective market discipline. Reform of ownership and governance structure are also important in enhancing managerial accountability of corporates as well as financial institutions.
