Employment,labor supply and real wages in market disequilibrium

The purpose of this paper is to provide estimates of a disequilibrium labor market model which has been fitted to the US private non-farm sector and to the manufacturing sector. After examining the rationale of the ‘minimum’-type disequilibrium model, we reject it in favor of a formulation suggested by Chow. The latter provides not only a wage adjustment mechanism, but also a quantity adjustment mechanism and treats wages and quantities symmetrically. The empirical findings for both sectors support the disequilibrium formulation employed and reject the equilibrium hypothesis for the labor market.     

CREDIBILITY, MACROECONOMIC FUNDAMENTALS AND MARKOV REGIME SWITCHES IN THE EMS

The main objective of this paper is to use the Markov regime‐switching modelling framework to describe and analyse the credibility of a number of countries participating in the European Monetary System during 1980–1998. Our credibility indicator, based on Hughes Hallet et al.'s (1997) methodology, is subject to discrete regime shifts and is made dependent on macroeconomic fundamentals. We carry out extensive testing to assess the specification of the Markov regime‐switching model and the potential existence of permanent breaks. A contribution of our paper is the specification of a multivariate Markov switching model that allows us to examine whether macroeconomic variables have asymmetric effects on credibility. Another contribution is the specification of a regime‐switching model with time‐varying transition probabilities, which enables us to determine whether changes in macroeconomic variables can trigger switches between the low and high credibility regimes. We find strong evidence of regime switching behaviour in all countries. Both the level of credibility and the transition probabilities display an asymmetric response to changes in macroeconomic variables, with the stance of fiscal policy exerting the most systematic influence in all countries.     

Another look at the linear q model: an empirical analysis of aggregate business capital spending with maintenance expenditures

Abstract .  The paper revisits the empirical investment literature, which has established that aggregate business fixed investment is not found to be related linearly to marginal or average Tobin's q . The theoretical background is extended here by developing a supply-side model where the depreciation rate of private capital is determined endogenously. The firm can either invest in 'new' capital, which adds directly to the existing capital stock at the presence of convex adjustment costs, or extend the durability of installed capital through maintenance expenditure, which affects its depreciation rate. The model shows that Tobin's q is then a positively related sufficient statistic for both components of aggregate capital expenditures. This central implication is tested empirically using aggregate time-series survey data from Canada on 'new' investment and maintenance expenditures covering the period 1956–93. The estimated relationships produce significant and plausible parameter estimates for the structural parameters of the q model.     

The monetary exchange rate model in the long run: An empirical investigation

The Monetary Exchange Rate Model in the Long Run: An Empirical Investigation. — This paper uses the Johansen multivariate cointegration method to examine three variants of the monetary approach to the long-run exchange rate model: flexible price, forward-looking and sticky price monetary models. Evidence is provided for four bilateral sterling exchange rates. The sensitivity of the results to the measurement of monetary aggregates is also examined. The cointegration results provide dismal evidence for the flexible price and forward-looking models irrespective of the measurement of money. The findings are more mixed for the sticky price model, particularly when broad money is used.     

The ERM Effect,Conflict and Inflation in the European Union

This paper investigates price inflation expectations and wage determination in the ERM member countries with the aim of assessing the importance of the ERM effect and distributional conflict. We have found strong evidence of an ERM effect in the inflationary process of participating countries, but this effect manifests itself primarily through structural changes in labour markets rather than through importing Bundesbank's reputation. This evidence questions the tendency to model the ERM as a credibility-reputation game. Inflation expectations for all ERM countries are strongly influenced by movements in unit labour costs and demand, and secondarily by world commodity and oil prices. The empirical results provide strong support for the conflict approach to wage inflation.     

Public Investment Rules and Endogenous Growth with Empirical Evidence From Canada

This paper examines theoretically and empirically the effects of public investmentrules on output growth in an economy with private and public capital. It is shownthat the decisions on public capital formation are closely associated with the growthrate of output and generate endogenous growth. A permanent change in the policyrule implies a new long-run growth rate of output, but the economy will onlygradually approach the new steady-state due to adjustment costs in private capitalaccumulation. The model predictions are tested using data from Canada for theperiod 1955-1999. The data support the endogenous growth hypothesis and thetwo central assumptions of the model: (i) the growth rate of output follows closelythe rate of infrastructure formation and (ii) private capital formation also followsthe rate of infrastructure formation but adjusts with a delay.
