Integration or Independence? An Alternative Assessment of Real Interest Rate Linkages in the European Union

The relationship between national real interest rates provides a valuable insight into the extent of economic and financial integration between countries. This paper tests for long‐run parity in ex post real interest rates among the major European Union (EU) countries over the period 1979–2003. The empirical investigation, however, is based on an alternative approach. Strong parity is determined by whether or not the first largest principal component (LPC), based on real interest rate differentials with respect to a chosen base country, is stationary. The qualitative outcome of the test is invariant to the choice of base country, and compared with alternative multivariate tests for long‐run parity, this methodology places less demands on limited data sets. Strong evidence of onshore parity occurs during 1979–1990 and 1993–2003 with the half‐life of a deviation to parity that varies towards 6 months. There is no evidence of long‐run parity among EU members during 1990–1993 despite the easing of remaining capital controls in 1990. Parity is rejected for a sample of non‐EU countries throughout the study period.     

Macroeconomic Control in the Transforming Chinese Economy: An Analysis of the Long‐Run Effect

This paper analyzes the issue of macroeconomic control in the Chinese economy where there is a dual structure (consisting of a state sector and a non‐state sector) and the financial sector is still under tight control by the government. Given the dual structure and financial repression, when inflation is a severe problem, the authors investigate whether it is possible for the government to bring inflation under control without hampering long‐term economic growth performance. The investigation is conducted within the context of an endogenous growth model that incorporates the two major institutional features of the transforming Chinese economy. The paper evaluates the long‐run effects of changes in government monetary and fiscal policies on the major macroeconomic aggregates. The analysis suggests that increasing in the interest rate on government bonds will reduce inflation without affecting the growth rate of output; while increasing the nominal interest rate on bank deposits will exert a stagflationary effect on the economy: raising the inflation rate but reducing the growth rate of output.     

Are migrants more skilled than non‐migrants? Repeat,return, and same‐employer migrants

Abstract.  I examine the determinants of inter‐state migration of adults within western Germany, using the German Socio‐Economic Panel from 1984–2000. Migrants who do not change employers represent one‐fifth of all migrants and have higher education and pre‐move wages than non‐migrants. Skilled workers thus have a low‐cost migration avenue that has not been considered in the previous literature. Other migrants are heterogeneous and not unambiguously more skilled than non‐migrants. I confirm that long‐distance migrants are more skilled than short‐distance migrants, as predicted by theory, and I show that return migrants are a mix of successes and failures. Most repeat migration is return migration. JEL classification: J6     

Predicting UK Business Cycle Regimes

This paper uses logistic regression to construct a one‐quarter ahead prediction model for classical business cycle regimes in the UK. The binary dependent variable is obtained by applying simple mechanical rules to date turning points in quarterly real GDP data from 1963 to 1999. Using a range of real and financial leading indicators, several parsimonious one‐quarter‐ahead models are developed for the GDP regimes, with model selection based on the SIC criterion. A real M4 variable is consistently found to have predictive content. One model that performs well combines this with nominal UK and German short‐term interest rates. The role of the latter emphasises the open nature of the UK economy.     

Stock Market Fluctuations and Money Demand in Italy, 1913–2003

This paper examines the impact of stock market fluctuations on money demand in Italy from a long‐run perspective. The money demand function estimated by Muscatelli and Spinelli (2000) for a long time span is utilized as a benchmark, adding to the specification information on share prices from the Milan Stock Exchange Reform of 1913 to recent years. For a shorter time period (1938–2003), annual observations on stock market capitalization and turnover velocity are also considered. The empirical findings suggest that stock market fluctuations help to explain temporary movements in liquidity preference, rather than its secular patterns. Overall, a positive association emerges between an index of stock market prices that includes dividends and real money balances; however, the estimated long‐run relationship is unstable. In a dynamic, short‐term specification of money demand, the estimated coefficient of deflated stock prices is positive, and therefore compatible with a wealth effect, in the years 1913–1980, while in the last two decades a substitution effect has prevailed and the correlation between money and share prices has been negative. This is likely to reflect a change in financial structure and the increasing role of opportunity costs defined over a wider range of assets. These results are confirmed by data on stock market capitalization. Moreover, in the recent period, stock market turnover and money growth are positively correlated .     

Seasonality, Cointegration, and Forecasting UK Residential Energy Demand

Much of the short‐run movement in energy demand in the UK is seasonal, and the contribution of long‐run factors to short‐run forecasts is slight. Nevertheless, using a variety of techniques, including a recently developed estimation procedure that is applicable irrespective of the orders of integration of the data, we obtain a long‐run income elasticity of demand of about one third, and we are unable to reject a zero price elasticity. An econometric model is shown to provide superior short‐run forecasts to well‐known seasonal time series models ex post , but is inferior to Box‐Jenkins SARMA models when the determinants themselves have to be forecast. However, the relatively short data sample and small number of forecasts suggest caution in generalising these results.     

Monetary policy in a cash‐in‐advance economy: employment, capital accumulation, and the term structure of interest rates

Abstract.  In this paper we study the effects of monetary policies on employment, capital accumulation, consumption, and the term structure of interest rates in a cash‐in‐advance economy, where money is required for consumption expenditures. Monetary policy involves targeting the inflation rate. The detailed dynamics of the model are fully worked out. As no numerical analysis is involved, we are able to identify very clearly the different channels through which monetary policy will impinge on the important macroeconomic variables. The model is also used to discuss the 'Great Canadian Slump.' JEL Classification: E52 and E43     

What drives the cross‐country growth and inequality correlation?

Abstract.  We present a neo‐classical model that explores the determinants of growth‐inequality correlation and attempts to reconcile the seemingly conflicting evidence on the nature of the growth‐inequality relationship. The initial distribution of human capital determines the long‐run income distribution and the growth rate by influencing the occupational choice of the agents. The steady‐state proportion of adults that innovates and updates human capital is path dependent. The output elasticity of skilled‐labour, barriers to knowledge spillovers, and the degree of redistribution determine the range of steady‐state equilibria. From a calibration experiment we report that a skill‐intensive technology, low barriers to knowledge spillovers, and high degrees of redistribution characterize the industrial countries with a positive growth‐inequality correlation. A negative correlation between growth and inequality arises for the group of non‐industrial countries with the opposite characteristics. JEL classification: E1, O4     

UK Utility Regulation: Licences, Commitment and Judicial Review

Abstract ** :  This paper analyses critically the claim made by Levy and Spiller that, in the context of UK utility regulation, licences operate as a 'technology of commitment'. The functional logic of delegation which underpins much principal–agent analyses is discussed, together with the credibility problem emerging from a divergence between a principal's long‐term and short‐term policies. Levy and Spiller contend that the UK has a successful model of utility regulation in part because of the use of licences which restrict the regulator from deviating from the broad substantive principles settled at the time of vesting. This contention is examined through the detailed consideration of five judicial review cases which have cast light on how, and to what extent, the licences restrict regulatory discretion .     

Viewpoint: Towards a solution to the puzzles in exchange rate economics: where do we stand?

Abstract.  This paper provides a selective overview of puzzles in exchange rate economics. We begin with the forward bias puzzle: high interest rate currencies appreciate when one might guess that investors would demand higher interest rates on currencies expected to fall in value. We then analyse the purchasing power parity puzzle: the real exchange rate displays no (strong) reversion to a stable long‐run equilibrium level. Finally, we cover the exchange rate disconnect puzzle: the lack of a link between the nominal exchange rate and economic fundamentals. For each puzzle, we critically review the literature and speculate on potential solutions. JEL classification: F31     

Long‐term Performance of New Equity Issuers, Venture Capital and Reputation of Investment Bankers

This study investigates the potential effects of investment‐banking reputation and venture capital on the long‐term performance of initial public offerings (IPOs) simultaneously. Our findings do not support the view that IPOs perform differently compared with other firms, with the only exception of venture‐backed IPOs. We show that venture‐backed IPOs are associated with long‐term gains when we account for investment bankers' reputation, size and book‐to‐market effects. Zero investment portfolios, based on combinations of underwriter's reputation and venture capital involvement's in IPOs, provide additional evidence in support of the view that venture‐backed IPOs, regardless of the reputation of underwriters, are associated with significant post‐issue gains. Our results also indicate that the reputation of investment bankers matters only in the absence of venture capital .     

Decentralized Policymaking in a Long‐run Growth Model with Seigniorage and Taxes

The paper introduces decentralized policymaking into a game‐theoretic model with output growth through capital accumulation, and in which the determination of taxes, seigniorage and the long‐run growth rate of the economy reflects the strategic interactions between the government, the central bank and the private sector. The paper investigates, among other things, the impact on the long‐run growth rate of a higher degree of inflation aversion of the central bank and a higher degree of inefficiency in the tax system.     

Interest Rates, Stock Returns and Credit Spreads: Evidence from German Eurobonds

We investigate daily variations in credit spreads on investment‐grade Deutschemark‐denominated Eurobonds during the challenging 1994–1998 period. Empirical results from a Longstaff and Schwartz (1995) two‐factor regression, extended for correlated spread changes and heteroskedasticity, indicate strong persistence in spread changes. Consistent with theory and previous findings, changes in spreads are significantly negatively related to the term‐structure level while, contrary to theory, the proxy for asset value does not yield a significant negative contribution. We even find a significant positive relation for Eurobonds with long maturity. Tentative interpretations are portfolio‐rebalancing activities or differing risk factor sensitivities on short‐ vs. long‐maturity bonds.     

The Co‐initial Swap Market Model

In this paper, we introduce a novel approach to the pricing and the risk management of generic European style interest‐rate derivatives. This new model has great flexibility and has the advantage of avoiding complex model calibration techniques typical of standard short‐rate models. Dynamics is assigned on a set of co‐initial forward swap rates, and arbitrage‐free restrictions are determined in a normal and lognormal setup. Model implementation and calibration are discussed, and details of two example applications are also presented.

Optimal Monetary Policy with Price and Wage Rigidities

In this paper, I search for an optimal configuration of parameters for variants of the Taylor rule by using an accurate second‐order welfare‐based method within a fully microfounded dynamic stochastic model, with price and wage rigidities, without capital accumulation. A version of the model with distortionary taxation is also explicitly tested. The model is solved up to second‐order solution. Optimal rules are obtained by maximizing a conditional welfare measure, differently from what has been done in the current literature. Optimal monetary policy functions turn out to be characterized by inflation targeting parameter lower than in empirical studies. In general, the optimal values for monetary policy parameters depend on the degree of nominal rigidities and on the role of fiscal policy. When nominal rigidities are higher, optimal monetary policy becomes more aggressive to inflation. With a tighter fiscal policy, optimal monetary policy turns out to be less aggressive to inflation. Impulse‐response functions based on second‐order model solution show a non‐affine pattern when the economy is hit by shocks of different magnitude .     

On model ambiguity and money neutrality

We solve for the equilibrium of a stochastic neo-classical continuous time model without and with money under model ambiguity. We show that: (i) the correction for ambiguity stemming from the money supply is nil at equilibrium; (ii) money is neutral with respect to the stock market equilibrium (the equity risk premium); (iii) money is not neutral with respect to consumption and capital accumulation, and its effect may be quantitatively substantial; (iv) the preference for model robustness affects all the real economic variables as well as the expected inflation rate and the nominal interest rate.     

Implications of Singapore's CPF Scheme on Consumption Choices and Retirement Incomes

Singapore has a unique policy of allowing the use of mandatory social security contributions to finance homeownership. An intertemporal model of housing demand is employed to demonstrate analytically that the CPF scheme can distort an individual's intertemporal and intratemporal consumption choices, and induce Singaporeans to demand more housing than they would otherwise. The withdrawals for housing have also affected the adequacy of CPF balances for financing retirement. Pegging the rate of return on CPF balances to a long‐term rate is the long‐term solution to curbing excessive withdrawals for housing, and ensuring the adequacy of CPF savings for financing retirement.     

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 nominal rate of interest, the rate of return on money, and inflationary expectations

This paper offers two modifications to the standard comparative-static analysis that help explain why nominal interest rates may either over- or under-adjust to a change in inflationary expectations, even in full general equilibrium: the inclusion of the real rate of return to money balances in commodity demand functions, and the presence of differing costs of obtaining information. In brief, the first factor may explain why nominal interest rates could over-adjust to a change in inflationary expectations, while the second may substitute for real balance effects in limiting the upward adjustment of nominal rates.     

Debt, liquidity and dynamics

Summary. Money, which provides liquidity, is distinct from debt. The introduction of a bank that issues money in exchange for debt and pays out its profit as dividend to shareholders modifies the model of overlapping generations. The set of equilibrium paths, their dynamic properties, as well as the scope and effectiveness of monetary policy are significantly altered: though low rates of interest are associated with superior steady state allocations, stability of the steady state may require a nominal rate of interest above a certain minimum: without production, a decrease in the nominal rate of interest may result in explosive behavior or convergence to an endogenous cycle, while in an economy with production, an increase in the nominal rate of interest may lead to indeterminacy and fluctuations.Received: 5 October 2004, Revised: 5 November 2004 JEL Classification Numbers: E30, E32, E50, E52.C.
