The purpose of this paper is to empirically determine the causes of worldwide diversity of inflation volatility. We show that higher degrees of political instability, ideological polarization, and political fragmentation are associated with higher inflation volatility.

Ramsey models of fiscal and monetary policy featuring time-separable preferences and a fixed supply of capital predict highly volatile inflation with no serial correlation. In this paper, we show that an otherwise-standard Ramsey model that incorporates capital accumulation and habit persistence predicts highly persistent inflation. The result depends on increases in either the ability to smooth consumption or the preference for doing so. The effect operates through the Fisher relationship: a smoother profile of consumption implies a more persistent real interest rate, which in turn implies persistent optimal inflation. Our work complements a recent strand of the Ramsey literature based on models with nominal rigidities. In these latter models, inflation volatility is lower than in the baseline model but continues to exhibit little persistence. We quantify the effects of habit and capital on inflation persistence and also relate our findings to recent work on optimal fiscal policy with incomplete markets.

In the article I discuss some possible explanations for two features of financial globalization over recent years; first, the fact that expected returns have fallen significantly in advanced countries, even though economic growth has accelerated; and second, the fact that capital is flowing from poor to rich countries rather than the other way round, a phenomenon known in the literature as the “Lucas Paradox”. The “incomplete” nature of globalization, notably the persistent differences in institutional quality between North and South, might explain both puzzles as well as the emergence of global imbalances. Alternative explanations based on a fall in risk premia and accommodative monetary policy conditions fit the facts less well. I then discuss the implications for monetary policy.

It is argued that government credibility is an important resource and that it can be improved by delegating decision-making competence beyond the nation-state. It is hypothesized that such delegation should result in higher income and growth. Some former British colonies retained the Judicial Committee of the Privy Council as their final court of appeals even after independence. This court is thus taken as a natural experiment to test our hypothesis. It turns out that retaining the jurisdiction is indeed significant for explaining economic growth.

What does the saving-investment (SI) relation really measure and how should the (SI) relation be measured? These are two of the most discussed issues triggered by the so called Feldstein-Horioka puzzle. Based on panel data we introduce a new variant of functional coefficient models that allow to separate long and short to medium run parameter dependence. We apply the latter to uncover the determinants of the SI relation. Macroeconomic state variables such as openness, the age dependency ratio, government current and consumption expenditures are found to affect the SI relation significantly in the long run.

We study how constrained fiscal policy can affect macroeconomic stability and welfare in a two-region model of a monetary union with sticky prices and distortionary taxation. Both government spending and taxes can be used to stabilize regional variables; however, the best welfare outcome is obtained under some tax variability and constant regional inflations. We use a variety of rules to characterize constrained fiscal policy and find that strict fiscal rules coupled with a monetary policy that targets union-wide inflation result in regional inflation stability and the welfare costs of such rules are not as unbearable as one would expect. Fiscal authorities can enhance welfare by targeting the regional output gap, while targeting regional inflation is less successful since inflation stability is guaranteed by the central bank.

We assume that, while the central bank has an information advantage in respect of aggregate productivity shocks, the private sector has superior knowledge of local disturbances. It is shown that there is no policy trade-off between inflation and employment stability: moreover macroeconomic outcomes are independent of the weight assigned to inflation by the central bank.

Although the case for trade liberalization is now well established, the case for financial liberalization is not, because the latter is associated with lending booms and crises. Some critics invoke as evidence the recent weak growth of Mexico, a prominent liberalizer. We argue that liberalization is beneficial despite the occurrence of crises. First, we show that financial liberalization has typically followed trade liberalization, and that both have led to faster growth, despite more frequent booms and busts. Second, we present a model that shows why, in countries with severe credit market imperfections, liberalization leads to faster growth and, as a by-product, to financial fragility. Third, comparing Mexico with this international norm, we show that liberalization and NAFTA have induced faster growth and investment but have not been enough: lack of structural reform and a protracted credit crunch generated bottlenecks that blocked further growth and led to a slowdown in exports.

We investigate identification issues in estimated Taylor rules. Embedding two alternative views about monetary policy, inertia versus serially correlated shocks, in a single equation, we show that using euro data, it is impossible to discriminate between these two competing representations.

We propose a general equilibrium model that explains the empirical evidence of the hump-shaped response of inflation to a monetary policy shock. The model replaces backward-looking indexation à la Christiano et al. [2005. Nominal rigidities and the dynamic effect of a shock to monetary policy. Journal of Political Economy 113(1), 1–45] with a dynamic externality into the production function of firms. The model, armed with sticky wages and variable capital utilization, has two offsetting effects on real marginal cost over the business cycle. First, increasing factor prices raise real marginal cost in response to an expansionary monetary policy shock in the intermediate run. Second, a dynamic externality reduces real marginal cost in the short run because it raises productivity in response to an increase in output following the shock. Overall, the resulting short-run decrease and intermediate-run increase in marginal cost replicate the hump-shaped behavior of inflation under purely forward-looking price and wage Phillips curves.

Focusing on policymaking under uncertainty, we analyze the monetary policy of the Bank of Japan (BOJ) in the early 1990s, when the bubble economy collapsed. Conducting stochastic simulations with a large- scale macroeconomic model of the Japanese economy, we find that the BOJf s monetary policy at that time was essentially optimal under uncertainty about the policy multiplier. On the other hand, we also find that the BOJ's policy was not optimal under uncertainty about inflation dynamics, and that a more aggressive policy response than actually implemented would have been needed. Thus, optimal monetary policy differs greatly depending upon which type of uncertainty is emphasized. Taking into account the fact that overcoming deflation became an important issue from the latter 1990s, it is possible to argue that during the early 1990s the BOJ should have placed greater emphasis on uncertainty about inflation dynamics and implemented a more aggressive monetary policy. The result from a counterfactual simulation indicates that the inflation rate and the real growth rate would have been higher to some extent if the BOJ had implemented a more accommodative policy during the early 1990s. However, the simulation result also suggests that the effects would have been limited, and that an accommodative monetary policy itself would not have changed the overall image of the prolonged stagnation of the Japanese economy during the 1990s.

Inflation differentials within European Monetary Union (EMU) are increasingly seen as exerting adverse effects on the price competitiveness of member countries’ firms and – given the common monetary policy within EMU – as being detrimental to euro-area economies, in particular to those with relatively high inflation rates. Using three simple measures of international price competitiveness for EMU countries, the paper analyses whether these indicators have displayed distinctive trends since the start of EMU and whether they converge with or diverge from their respective fundamental value. It is found that all three indicators suggest a gain in competitiveness for the German economy and a corresponding loss for Italy, Portugal and Spain. Two of the indicators, however, suggest that these trends reduce former disparities and, thus, contribute to a convergence of competitiveness within EMU while the third would imply the opposite.

Wolfgang Lemke Discussion Paper Series 1: Economic Studies. 2007.  No. 13/2007.
A joint model of macroeconomic and term structure dynamics is specified and estimated for the euro area. The model comprises a backward-looking Phillips curve, a dynamic IS equation, a monetary policy rule as well as a specification of the dynamics of trend growth and the natural real interest rate. Under the condition of no arbitrage, yields of all maturities are affine functions of the macroeconomic driving forces. With the exception of a shock to potential output growth, the response of short-term yields to macroeconomic shocks is generally stronger than that of long-term yields. Impulse responses of all bond yields are fairly persistent, which reflects the persistence of their macroeconomic driving forces. Across the whole maturity spectrum, about ninety percent of the variation in yields is explained jointly by monetary policy shocks and shocks to the natural real rate of interest; the relative contribution of the latter shock increases with time to maturity. Cost-push shocks explain at most eight percent, while shocks to the output gap play an even less important role.

Carolyn Sissoko Economics Discussion Papers. 2007.  No. 2007-16.
Using the monetary model developed in Sissoko (2007), where the general equilibrium assumption that every agent buys and sells simultaneously is relaxed, we observe that in this environment fiat money can implement a Pareto optimum only if taxes are type-specific. We then consider intermediated money by assuming that financial intermediaries whose liabilities circulate as money have an important identifying characteristic: they are widely viewed as default-free. The paper demonstrates that default-free intermediaries who issue credit lines to consumers can resolve the monetary problem and make it possible for the economy to reach a Pareto optimum. We argue that our idealized concept of financial intermediation is a starting point for studying the monetary use of credit.

This paper answers the question which developing countries have gained and which have lost in the international division of labor during the last thirty years. The indicators used are GDP per capita in constant purchasing power parity and relative distance to the United States. Nearly all developing countries have improved in absolute terms over the last thirty years; many, among them China and India with large populations, have also reduced their relative distance to the United States. The paper classifies developing countries and discusses impediments to economic development and core elements of a growth strategy.

Extending the IS-MP-IA model (Romer, 2000), we find that equilibrium output in Singapore is negatively affected by the expected inflation rate and the world interest rate and positively influenced by real appreciation, stock market performance, and world output. Equilibrium GDP would rise by 0.872% if the real effective exchange rate rises by 1%. The coefficient of real government deficit spending is found to be insignificant, suggesting that pursuing fiscal discipline and budget surpluses in the long run by the Singapore government is appropriate.

Emerging market financial crises are abrupt and dramatic, usually occurring after a period of high output growth, massive capital flows, and a boom in asset markets. This paper develops an equilibrium asset-pricing model with informational frictions in which vulnerability and the crisis itself are consequences of the investor optimism in the period preceding the crisis. The model features two sets of investors, domestic and foreign. Both sets of investors learn from noisy signals, which contain information relevant for asset returns and formulate expectations, or "beliefs," about the state of productivity. We show that, if preceded by a sequence of positive signals, a small, negative noise shock can trigger a sharp downward adjustment in investors' beliefs, asset prices, and consumption. The magnitude of this downward adjustment and sensitivity to negative signals increase with the level of optimism attained prior to the negative signal.

Ruy Lama, Juan Pablo Medina IMF, Working Paper. 2007. 
This paper studies optimal monetary policy in a two-sector small open economy model under segmented asset markets and sticky prices. We solve the Ramsey problem under full commitment, and characterize the optimal monetary policy in a calibrated version of the model. The findings of the paper are threefold. First, the Ramsey solution mimics the allocations under flexible prices. Second, under the optimal policy the volatility of non-tradable inflation is close to zero. Third, stabilizing nontradable inflation is optimal regardless of the financial structure of the small open economy. Even for a moderate degree of price stickiness, implementing a monetary policy that mitigates asset market segmentation is highly distortionary. This last result suggests that policymakers should resort to other policy instruments in order to correct financial imperfections.

In this paper, the IMF's new Global Economy Model (GEM) is used to estimate the relative importance of a number of factors argued to explain the differences in the trends in core inflation and relative prices in the United Kingdom, the Euro Area and the United States. The simulation results indicate that while the direct effect of globalization has had a larger effect in the United Kingdom than in either the United States or the Euro Area, it explains only a portion of the developments and U.K. specific factors played an important role.

Keiko Honjo IMF, Working Paper. 2007.  No. 07/199.
The present formulation of the golden rule in the United Kingdom allows fiscal performance to be tested explicitly on an ex-post basis. However, it requires precise dating of the economic cycle, which can lead to significant controversy. Also, the need to aim for current balance or better "over the cycle" may force fiscal policy to be procyclical toward the end of cycles. Using dynamic stochastic simulations, the paper suggests that making the formulation of the golden rule forward-looking and independent of the dating of the economic cycle would reduce the risk of procyclicality and enhance macroeconomic stability.
