Index-linked bonds from an academic,market and policy-making standpoint

The view put forward in this paper is that the index-linking of long-term public debt today represents a financial instrument thatfostersa low average rate of inflation. In particular, bonds that are fully linked to the prices of a representative basket of goods and services permit a reduction in the inflation risk premium, which weighs significantly on the nominal cost of the public debt and,ex post, gives rise to substantial real costs that distort the mechanisms of allocation and distribution and, ultimately, could lead to the debt becoming unsustainable. After re-examining the reasons for the “orthodox ” aversion to index-linking —notably on the part of the monetary authorities of the more stable countries and especially the Bundesbank —the case is put for the leading industrial countries, and notably Italy, to issue index-linked government bonds. By issuing such bonds, the Treasuries of the various countries would send a strong stabilizing signal to the markets because recourse to the inflation tax in the future would no longer be advantageous, reduce the real cost of government borrowing by eliminating the inflation risk premium that currently has to be paid on issues with fixed nominal interest rates, benefit from the positive correlation between the quality of revenue and expenditure, and obtain valuable information on forward inflation rates and the real interest rates implicit in the prices of the bonds. The long-term real interest rate offered by index-linked bonds would act as a sort of “lighthouse ” set up by the monetary authorities to illuminate the path of economic growth and enable operators and markets to co-ordinate their actions more effectively.     

Expectations,capital formation,sales and capacity utilization

A model is developed and tested to relate capital formation, sales and capacity utilization in manufacturing to expected inflation and expected interest rates through anticipated real wealth effects. Expected future inflation causes purchases of storeable manufactured goods in advance and accumulations of physical capital. The former increases capacity utilization, while the latter decreases it. Expected increases in interest rates have an impact on sales and capital formation opposite to that of expected increases in prices. Finally, if expected inflation is accompanied by a propertionate increase in expected interest rates, sales decline more than capital formation, and hence capacity utilization contracts.     

INFLATION,OUTPUT, AND WELFARE*

We study the effects of anticipated inflation on aggregate output and welfare within a search‐theoretic framework. We consider two pricing mechanisms: ex post bargaining and a notion of competitive pricing. Under bargaining, the equilibrium is generically inefficient and an increase in inflation reduces buyers' search intensities, output, and welfare. If prices are posted and buyers can direct their search, search intensities are increasing with inflation for low inflation rates and decreasing for high inflation rates. The Friedman rule achieves the efficient allocation, and inflation always reduces welfare, although it can have a positive effect on output for low inflation rates.     

Inventory accumulation and expectations of real income,inflation and interest rates

A model is developed and tested to relate three categories of inventory accumulation to expectations of real income, inflation and interest rates through anticipated real corporate wealth effects. Expected future inflation leads firms to accumulate more inventories in advance financing them by means of ‘liquid’ assets to offset an anticipated loss of real wealth. Expected increases in interest rates have an impact on inventory accumulation opposite to that of expected future inflation. Past wealth effects are also allowed for by means of the accelerator principle. Finally, the growth rate of real income generally has a signifiant influence on inventory accumulation.     

Currency Exposure to Downside Risk: Which Fundamentals Matter?

I study whether or not countries' macroeconomic characteristics are systematically related to their currencies' exposure to the downside market risk. I find that the currency downside risk is strongly associated with the local inflation rate, real interest rate and net foreign asset position. Currencies of countries with high inflation and real interest rates and negative net foreign asset position (debtor countries) are more exposed to the downside risk whereas currencies of countries with low inflation and real interest rates and positive net foreign asset position (creditor countries) exhibit “safe haven” properties. The local real interest rate has the highest explanatory power in accounting for the cross‐section of currency exposure to the downside risk. This suggests that the high currency exposure to the downside risk is a consequence of investments in high‐yield risky countries and flight from them in “hard times”.     

What determines China's inflation?

We examine determinants of inflation in China. Analyses of both year-on-year and month-on-month growth data confirm that excess liquidity, output gap, housing prices, and stock prices positively affect inflation. Impulse response analyses indicate that most effects occur during the initial five months and disappear after ten months. Effects of real interest rates and exchange rates on inflation are relatively weak. Our results suggest that the output gap is as important as excess liquidity in explaining the inflation trajectory. The central bank should closely monitor asset prices given their spillovers to inflation. Currently liquidity measures are still central for controlling inflation, but further liberalization of interest rates and exchange rates are crucial.     

What drives the global official/policy interest rate?

We construct a GFAVAR model with newly released global data from the Federal Reserve Bank of Dallas to investigate the drivers of global official/policy interest rate. We find that 66% of movement in global official/policy interest rates is attributed to changes in global monetary aggregates (23%), oil prices (19%), global output (16%) and global prices (8%). Global official/policy interest rates respond significantly to increases in global output, inflation and oil prices. Increases in global policy interest rates are associated with reductions in global prices and global output. The response in official/policy interest rate for the emerging countries is more to global inflation, for the advanced countries (excluding the U.S.) is more to global output, and for the U.S. is to both global output and inflation.     

Price bounds on bond options,swaptions, caps,and floors assuming only nonnegative interest rates

This paper derives bounds on the prices of European and American bond options, caps, floors, and European swaptions assuming only absence of arbitrage and nonnegative interest rates. The bounds are considerably tighter than Merton's bounds on stock option prices, especially for options on short-term bonds or swaps and short-term caps and floors. For American bond options, it is important to distinguish between options on the quoted (“clean”) bond price and options on the actual (“dirty”) bond price. For example, it is shown that it may be optimal to exercise an American call on the quoted bond price early even if the underlying bond makes no payments in the remaining life of the option.     

Money, expectations, and interest rates

This paper employs a model of nominal interest rate determination in a framework of rational expectations of inflation. Hypotheses are developed with respect to relative impacts of predictable and unpredictable changes in money supply. These hypotheses are tested using quarterly Italian data from 1966–1975. The nominal monetary base is the measure of money employed and one private and two government bond rates measure nominal interest rates. The results are insensitive to variations in estimation procedure and specification of adjustment processes (and even predictive functions for the monetary base). The rational expectations formulation is well supported in every case.     

THE TREATMENT OF “HOME OWNERSHIP” IN THE CPI*

This paper explores the imputed service price approach to the pricing of the services of consumer-owned-and-used durables in the construction of the consumer price index, using the services of owner-occupied housing as an illustration. A theoretical framework for analyzing this question is first developed. Certain practical problems are then discussed. The conceptual difficulty of constructing an appropriate rate of return on the basis of available data on interest rates and house prices, in the context of inflation, is explored. Two arguments are advanced that statistical agencies ought not to follow the imputed service price approach in pricing the services of owner-occupied dwellings and other consumer durables. On the one hand, nominal interest rates will, in any short period, reflect monetary policy and not any change in the money “rental” of owner-occupied houses. Second, movements in nominal interest rates will also reflect changes in the money price of pure consumption goods, as well as changes in the money price of houses. The argument is extended to other consumer durables and, in the limiting case, to monetary balances, and it is concluded that in all but trivial cases the application of the service price approach leads to price movements of little or no meaning.     

Inflation targeting and the need for a new central banking framework

This article critically analyzes inflation targeting (IT) both theoretically and empirically. IT came into prominence in the 1990s and 1 central bank after another adopted this regime in the 1990s and 2000s. Proponents of IT mainly argued that IT regime was successful on the grounds that it resulted in lower inflation rates and hence better economic performances. However, inflation rates in the world were in a downward trend from the 1980s well into the 2000s, and both IT and non-IT regimes managed to decrease their inflation rates. In addition, focusing too much on price stability through IT paved the way for permanently higher than necessary interest rates and disinflationary “tight” monetary policy periods when inflation rate was above an arbitrarily targeted level. Tight monetary policy can and do affect the real economy negatively and overemphasizing price stability may hurt the economy in terms of lower potential output, decreasing investment and more unequal income distribution. Post Keynesians offer valuable alternatives within the framework of parking-it approach to the existing monetary policy paradigm. Our main conclusion is that central banks should set the policy interest rate as low as possible and keep it there, in line with Keynesian “cheap money” policy.     

A graphical exposition of a more complete Keynesian system

This paper uses an expanded version of the widely cited Smith model to show the classical natural rate of interest and employment results as a special case of a more general Keynesian model. The model's equilibrium level of employment and real interest rate depend on the inflation rate. The classical results apply to changes in the price level while the Keynesian results apply to changes in the inflation rate. The model assumes inflation is anticipated in equilibrium. Violation of the classical results does not depend on market imperfections such as sticky prices or information costs.     

State of confidence,overborrowing and macroeconomic stabilization in out-of-equilibrium dynamics

We model macroeconomic instability as the outcome of the dynamic interaction between debt accumulation and the “state of confidence” in a small open economy with a super-fixed exchange-rate arrangement. We use a system dynamic approach and show that instability is a likely feature when macroeconomic behaviour is characterized by out-of-equilibrium dynamics with balance-sheet effects and deviation amplifying expectation formation rules that interact endogenously. We address the issue of the macroeconomic stabilization puzzle and carry out a quantitative evaluation based on sensitivity analysis with reference to Argentina, during the currency-board arrangement. We find that a tight fiscal policy is likely to be destabilizing inasmuch as it adds to the fall in expenditure, output and the “state of confidence”. On the other side, a traditional monetary policy can fail in switching off macroeconomic instability if the reduction in interest rates does not compensate for the fall in the “state of confidence”, whilst a direct stimulus to aggregate expenditure is required to avoid an economic collapse.     

Excess comovements between the euro/US dollar and pound sterling/US dollar exchange rates

ABSTRACT

The aim of this article is to discuss excess comovements of the euro/US dollar and pound sterling/US dollar exchange rates, i.e. we look for comovements of exchange rates which are stronger than implied by the fundamentals. The results of the empirical analysis provide evidence that excess comovements exist for the two exchange rates. A long-run analysis of correlations can verify that a link exists between the correlation dynamics of exchange rates, relative inflation rates, long-term interest rates, economic sentiments and money supply. We find that common movements of money supply, prices and economic sentiments each play a major role in comovements of the exchange rates. From the investigation of the two exchange rates, we conclude that macroeconomic fundamentals can account for the comovement but that common non-fundamental factors also have major significance for the exchange rates.     

Anticipated Fiscal Policy Changes and Goods Market Adjustments

Abstract. Government policies are frequently known to be temporary and thus their termination is perfectly anticipated. These foreseen policy changes must be consistent with equilibrium in both the goods market and asset markets. Potential problems arise because prices often play dual roles, both as final goods prices, and as asset prices, as components of rates of return. We show how the economy accommodates an anticipated policy change depends upon its production flexibility and its structure. With flexible investment, an anticipated reduction in government expenditure is fully accommodated by capital accumulation. When investment involves adjustment costs, the marginal utility of wealth and the price of capital both jump so as to maintain equality among rates of return. Goods market clearance is maintained by a combination of increases in consumption and investment. Extensions of the model to include inventories and to a small open economy are also considered and contrasted.     

INTEREST RATE VOLATILITY AND EXCHANGE RISK: NEW RULES FOR A COMMON MONETARY STANDARD

How does the choice of an exchange rate regime influence the volatility of interest rates? Are floating exchange rates useful “shock absorbers” that dampen fluctuations in domestic interest rates and prices or do they create additional risk that increases interest rate volatility and segments the international capital market? The answers are best seen in historical perspective.     

Profit Differences and Corporate Power: Some Empirical Surprises

Inflation targeting is currently the policy of choice for central banks. This policy invariably targets consumer price inflation, which is only one of many available price level indices (such as prices of new investments and house prices). As there is no stable relationship between these price levels, and as differences in developments between the different price levels might induce destabilizing behavior, there is no reason why “low and stable” consumer price inflation should guarantee monetary and financial stability. Following John Maynard Keynes, a “low and stable” increase of average nominal wages might do a better job. As price levels are designed to estimate the purchasing power of spending power and as income, and spending power are used to not just consume or invest but also to pay down many kinds of (gross) debt, it is advisable to use a joint definition of monetary and financial stability, which combines stable purchasing power of monetary income with a stable ability of households and companies to pay off debts.     

Global Imbalances and the Financial Crisis: Reassessing the Role of International Finance

Global current account imbalances have recently been singled out by many as a key factor contributing to the global financial crisis. Current account surpluses in several emerging market economies are said to have put significant downward pressure on world interest rates, thereby fueling a credit boom and risk taking in major advanced economies with current account deficits (the “excess saving” view). We argue that this perspective on global imbalances bears reconsideration. We highlight two conceptual problems: (i) explaining market interest rates through the saving-investment framework; and (ii) drawing inferences about a country's cross-border financing activity based on observations of net capital flows. We trace the shortcomings of this perspective to a failure to consider the distinguishing characteristics of a monetary (credit) economy. We conjecture that the main macroeconomic cause of the financial crisis was not “excess saving” but the “excess elasticity” of the international monetary and financial system.     

Inflation, price dispersion, and market structure

In this paper, we use a novel data set containing prices from bazaars, convenience stores, and supermarkets in Istanbul to re-examine the relationship between price dispersion and inflation. Although existing evidence is mixed, we find positive and significant relationships between dispersion, on the one hand, and lagged dispersion and unexpected product-specific inflation on the other. We also find evidence that dispersion is initially decreasing in anticipated aggregate inflation but is eventually increasing. Finally, average price duration and dispersion are lowest in the bazaar. This is intuitive, since menu and search costs should be minimal in that market structure.
